Validation of inpatient experience questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: A validation survey was carried out in this study to assess the acceptability, validity and reliability of the Hong Kong Inpatient Experience Questionnaire (HKIEQ), which was newly developed to measure patient experiences of hospital care in Hong Kong (HK). DESIGN: Cross-sectional validation survey. MAIN OUTCOME MEASURES: Principal component exploratory factor analysis assessed the construct validity of the questionnaire. Cronbach's alpha coefficients and Spearman's rank correlation coefficient estimated the reliability of the instrument. Acceptability of the questionnaire regarding the percentage of missing value of individual items was also assessed. RESULTS: A total of 511 patients discharged from public hospitals in HK were interviewed. Low percentage of missing value (0.2 to 21.3%) showed high acceptability. Nine dimensions of hospital care explaining 75.4% of the variance were derived from factor analysis and content validity. These items showed satisfactory internal reliability consistency (0.49 to 0.97). Test-retest reliability ranged from 0.36 to 0.96. CONCLUSIONS: The HKIEQ performed well on several psychometric indicators and is a promising measure of patient experience with public hospital inpatient care in HK. The findings provided important insight on developing tools to measure patient experience in hospitals to improve the quality of care and to lay the foundation for further research on patient expectations and needs regarding hospitalization.

Análise da correlação entre limiares auditivos, questionários validados e medidas psicoacústicas em pacientes com zumbido/ Correlation analysis of hearing thresholds, validated questionnaires and psychoacoustic measurements in tinnitus patients  

Scientific Electronic Library Online (English)

Full Text Available Abstract in portuguese Uma das principais dificuldades nos estudos clínicos sobre zumbido reside na falta de consenso sobre os métodos de mensuração. OBJETIVO: Avaliar a correlação entre os limiares audiométricos, pitch matching (PM), minimum masking level (MML), Tinnitus Handicap Inventory (THI) e o Inventário de Depressão de Beck (BDI) em pacientes com zumbido. MODELO DE ESTUDO: Prospectivo, coorte transversal. MATERIAL E MÉTODO: 48 pacientes com zumbido como queixa principal foram (more) submetidos aos testes audiométricos e questionários acima descritos. Os dados foram comparados estatisticamente para as correlações entre os métodos. RESULTADOS: Não houve correlação estatisticamente significativa entre o THI e MML, tanto em pacientes com BDI acima e abaixo de 14 pontos, bem como entre a frequência de pior limiar auditivo e o Pitch matching e entre a frequência de "cut-off" e o PM nos pacientes com curvas descendentes em rampa. CONCLUSÕES: Não existe correlação estatisticamente significativa entre as medidas psicoacústicas do zumbido, os limiares audiométricos e os questionários de avaliação. O zumbido é um sintoma muito complexo e avaliações isoladas pelos métodos acima não são satisfatórias. Abstract in english One of the most criticized points in tinnitus clinical studies arise from the lack of consensus about measurement methods. AIM: To evaluate the correlation between audiometric thresholds, pitch matching (PM), minimum masking level (MML), Tinnitus Handicap Inventory (THI) and the Beck Depression Inventory (BDI) in tinnitus patients. STUDY DESIGN: Prospective, cross-sectional. MATERIALS AND METHODS: Subjects were submitted to tonal audiometry, PM and MML for tinnitus. They (more) also filled out the THI and BDI. Data was statistically compared for correlation purposes between audiometric thresholds, psycho-acoustic measures and questionnaires. RESULTS: There was no statistically significant correlation between THI and MML, both in patients with BDI scores under and over 14 points. There was no statistically significant correlation between the worst hearing frequency and PM, as well as between the cut-off frequency and the PM in patients with descending hearing curves in their audiograms. CONCLUSIONS: There is no statistically significant correlation between psycho-acoustic measures (PM and MML), audiometric thresholds, THI and BDI. Tinnitus is a very complex symptom and isolated measures by psycho-acoustic methods; tinnitus and depression questionnaires are not satisfactory.

Orthorexia nervosa: validation of a diagnosis questionnaire.  

UK PubMed Central (United Kingdom)

AIM: To validate a questionnaire for the diagnosis of orhorexia oervosa, an eating disorder defined as "maniacal obsession for healthy food". MATERIALS AND METHODS: 525 subjects were enrolled. Then they were randomized into two samples (sample of 404 subjects for the construction of the test for the diagnosis of orthorexia ORTO-15; sample of 121 subjects for the validation of the test). The ORTO-15 questionnaire, validated for the diagnosis of orthorexia, is made-up of 15 multiple-choice items. RESULTS AND CONCLUSION: The test we proposed for the diagnosis of orthorexia (ORTO 15) showed a good predictive capability at a threshold value of 40 (efficacy 73.8%, sensitivity 55.6% and specificity 75.8%) also on verification with a control sample. However, it has a limit in identifying the obsessive disorder. For this reason we maintain that further investigation is necessary and that new questions useful for the evaluation of the obsessive-compulsive behavior should be added to the ORTO-15 questionnaire.

Polish validation of Brace Questionnaire.  

UK PubMed Central (United Kingdom)

PURPOSE: The aim of the study was to undertake the process of cultural adaptation of the Brace Questionnaire (BrQ) into Polish. METHODS: The BrQ is an instrument for measuring the quality of life of scoliotic adolescents who are being treated conservatively with wearing a corrective brace. The BrQ consists of 34 Likert-scale items related to eight domains. The translation from the original Greek into Polish was performed. The process of cultural adaptation of the questionnaire was in accordance with the guidelines of the International Quality of Life Assessment Project. It involved 35 adolescents, aged between 10.0 and 16.0 years, all with adolescent idiopathic scoliosis with mean Cobb angle of 35.1 ± 10.6 degrees, and all wearing the same kind of brace (Chêneau orthosis) for more than 3 months. Statistical analysis calculated the reliability (internal consistency), floor and ceiling effects of the BrQ. RESULTS: The internal consistency was satisfactory; Cronbach's alpha coefficient was 0.94. There was no floor or ceiling effects. CONCLUSIONS: Polish version of the BrQ is reliable and can be used in adolescents with idiopathic scoliosis wearing the brace to assess their quality of life.

Construct validity of writing motivation Questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available The article reports results of two consecutive studies designed to understand construct validity of writing motivation and to examine its utility in the prediction of academic achievement. In first study, data were collected from 884 students of primary education through writing motivation questionnaire with seven domains (Dutta Roy, 2003). Correspondence analysis reveals two latent traits (intrinsic and extrinsic) of writing motivation. In the second study, writing motivation questionnaire was administered to 200 students and their academic performances in schools were collected. Results reveal inverse relation between latent traits. Composite scores of intrinsic writing motivation were positively and those of extrinsic writing motivation were negatively correlated with academic performance.

A PHYSICAL ACTIVITY QUESTIONNAIRE: REPRODUCIBILITY AND VALIDITY  

Directory of Open Access Journals (Sweden)

Full Text Available This study evaluates the Quantification de L'Activite Physique en Altitude chez les Enfants (QAPACE) supervised self-administered questionnaire reproducibility and validity on the estimation of the mean daily energy expenditure (DEE) on Bogotá's schoolchildren. The comprehension was assessed on 324 students, whereas the reproducibility was studied on a different random sample of 162 who were exposed twice to it. Reproducibility was assessed using both the Bland-Altman plot and the intra-class correlation coefficient (ICC). The validity was studied in a sample of 18 girls and 18 boys randomly selected, which completed the test - re-test study. The DEE derived from the questionnaire was compared with the laboratory measurement results of the peak oxygen uptake (Peak VO2) from ergo-spirometry and Leger Test. The reproducibility ICC was 0.96 (95% C.I. 0.95-0.97); by age categories 8-10, 0.94 (0.89-0. 97); 11-13, 0.98 (0.96- 0.99); 14-16, 0.95 (0.91-0.98). The ICC between mean TEE as estimated by the questionnaire and the direct and indirect Peak VO2 was 0.76 (0.66) (p<0.01); by age categories, 8-10, 11-13, and 14-16 were 0.89 (0.87), 0.76 (0.78) and 0.88 (0.80) respectively. The QAPACE questionnaire is reproducible and valid for estimating PA and showed a high correlation with the Peak VO2 uptake

Selective Mutism Questionnaire: measurement structure and validity.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To evaluate the factor structure, reliability, and validity of the 17-item Selective Mutism Questionnaire (SMQ). METHOD: Diagnostic interviews were administered via telephone to 102 parents of children identified with selective mutism (SM) and 43 parents of children without SM from varying U.S. geographic regions. Children were between the ages of 3 and 11 inclusive and comprised 58% girls and 42% boys. SM diagnoses were determined using the Anxiety Disorders Interview Schedule for Children-Parent Version; SM severity was assessed using the 17-item SMQ; and behavioral and affective symptoms were assessed using the Child Behavior Checklist. An exploratory factor analysis was conducted to investigate the dimensionality of the SMQ and a modified parallel analysis procedure was used to confirm exploratory factor analysis results. Internal consistency, construct validity, and incremental validity were also examined. RESULTS: The exploratory factor analysis yielded a 13-item solution consisting of three factors: social situations outside of school, school situations, and home and family situations. Internal consistency of SMQ factors and total scale ranged from moderate to high. Convergent and incremental validity was also well supported. CONCLUSIONS: Measure structure findings are consistent with the three-factor solution found in a previous psychometric evaluation of the SMQ. Results also suggest that the SMQ provides useful and unique information in the prediction of SM phenomena beyond other child anxiety measures.

Brazilian Portuguese validation of Mood Disorder Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Mood Disorder Questionnaire (MDQ) is a screening instrument for bipolar spectrum disorders already validated in many languages. METHODS: Patients from 2 psychiatric outpatient facilities were diagnosed with bipolar disorder (BD) type I and II and major depression according to the mood module of the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (SCID), Axis I Disorders--Clinician Version. In addition, a control group of healthy subjects was selected. The diagnostic interviews were used as the gold standard against which to investigate the performance of the MDQ. The MDQ was administered to 153 subjects, distributed among 4 groups. We analyzed the test reliability and discriminative capacity of the MDQ for the detection of patients with BD. RESULTS: Based on the SCID, Axis I Disorders--Clinician Version, 52 subjects (33.3%) presented a bipolar spectrum disorder (type I, II, or not otherwise specified), 48 (32.4%) were diagnosed as having unipolar depressive disorder, whereas 54 (35.3%) were unaffected by any type of psychiatric disorder (had no psychiatric disorder according to SCID results). The sensitivity for bipolar disorder was 0.72 (bipolar I disorder, 0.81; bipolar II disorder, 0.58; and bipolar disorder not otherwise specified, 0.69), with specificity of 0.95. The Brazilian Portuguese MDQ demonstrated adequate internal consistency (Cronbach ? = .87). LIMITATIONS: Recruiting patients attending tertiary services may inflate the performance of the MDQ. CONCLUSIONS: The performance of the Brazilian Portuguese MDQ is comparable with other language validations. In a psychiatric outpatient sample, the Brazilian Portuguese MDQ proves to be a feasible and reliable screening instrument.

Validation of the pain sensitivity questionnaire in chronic pain patients.  

UK PubMed Central (United Kingdom)

Recently, a self-rating measure for pain perception based on imagined painful daily life situations, the Pain Sensitivity Questionnaire (PSQ), has been developed and shown to correlate with experimentally obtained pain intensity ratings in healthy subjects. Here, we assessed the validity of the PSQ for investigation of general pain perception (ie, pain perception outside the site of clinical pain) in chronic pain patients. PSQ scores were obtained in 134 chronic pain patients and compared to those of 185 healthy control subjects. In a subgroup of 46 chronic pain patients, we performed experimental pain testing outside the clinical pain site, including different modalities (heat, cold, pressure, and pinprick) and different measures (pain thresholds, pain intensity ratings). Results show that PSQ scores were significantly correlated with both experimental pain intensity ratings (Pearson's r=0.71, P<.001) and experimental pain thresholds (r=-0.52, P<.001). In addition, chronic pain patients exhibited significantly elevated PSQ scores as compared to healthy controls, consistent with the generalized increase of experimentally determined pain perception that has repeatedly been reported in chronic pain patients. These results demonstrate that the PSQ constitutes a valid self-rating measure of pain perception outside the clinical pain site in chronic pain patients and might serve as an alternative to experimental assessment of pain perception outside the clinical pain site in situations where experimental pain testing is not feasible.

The Danish anal sphincter rupture questionnaire: Validity and reliability  

DEFF Research Database (Denmark)

Objective. To revise, validate and test for reliability an anal sphincter rupture questionnaire in relation to construct, content and face validity. Setting and background. Since 1996 women with anal sphincter rupture (ASR) at one of the public university hospitals in Copenhagen, Denmark have been offered pelvic floor muscle examination and instruction by a specialist physiotherapist. In relation to that, a non-validated questionnaire about anal and urinary incontinence was to be answered six months after childbirth. Method. The original questionnaire was revised and a pilot test was performed among health care personnel, followed by an expert panel discussion. Ten women were interviewed about their understanding and attitude toward answering the questionnaire and it was pre-tested on 52 women with ASR. The questionnaire was revised five times during the validation process. The final version was test-retested among 20 women with ASR. Results. The questionnaire revealed typical problems after ASR. The length, use of language, and the way the questionnaire was constructed, was deemed appropriate. The reliability test showed good to very good correlation (Kappa values from 0.733 to 0.923) in all main questions but one. Two questions needed further explanation. Seven women made minor errors. Conclusion. The validated Danish questionnaire has a good construct, content and face validity. It is a well accepted, reliable, simple and clinically relevant screening tool. It reveals physical problems including sexual problems, impact on quality of life and need for treatment among women 6-8 months after ASR.

Validation of new psychosocial factors questionnaires: a Colombian national study.  

UK PubMed Central (United Kingdom)

BACKGROUND: The study of workers' health problems possibly associated with stressful conditions requires valid and reliable tools for monitoring risk factors. The present study validates two questionnaires to assess psychosocial risk factors for stress-related illnesses within a sample of Colombian workers. METHODS: The validation process was based on a representative sample survey of 2,360 Colombian employees, aged 18-70 years. Worker response rate was 90%; 46% of the responders were women. Internal consistency was calculated, construct validity was tested with factor analysis and concurrent validity was tested with Spearman correlations. RESULTS: The questionnaires demonstrated adequate reliability (0.88-0.95). Factor analysis confirmed the dimensions proposed in the measurement model. Concurrent validity resulted in significant correlations with stress and health symptoms. CONCLUSIONS: "Work and Non-work Psychosocial Factors Questionnaires" were found to be valid and reliable for the assessment of workers' psychosocial factors, and they provide information for research and intervention.

Child abuse: validation of a questionnaire translated into Brazilian Portuguese  

Directory of Open Access Journals (Sweden)

Full Text Available This study sought to validate the Portuguese translation of a questionnaire on maltreatment of children and adolescents, developed by Russell et al. and to test its psychometric properties for use in Brazil. The original questionnaire was translated into Portuguese using a standardized forward-backward linguistic translation method. Both face and content validity were tested in a small pilot study (n = 8). In the main study, a convenience sample of 80 graduate dentistry students with different specialties, from Curitiba, PR, Brazil, were invited to complete the final Brazilian version of the questionnaire. Discriminant validity was assessed by comparing the results obtained from the questionnaire for different specialties (pediatric dentistry, for example). The respondents completed the questionnaire again after 4 weeks to evaluate test-retest reliability. The comparison of test versus retest questionnaire answers showed good agreement (kappa > 0.53, intraclass correlation > 0.84) for most questions. In regard to discriminant validity, a statistically significant difference was observed only in the experience and interest domains, in which pediatric dentists showed more experience with and interest in child abuse compared with dentists of other specialties (Mann-Whitney test, p < 0.05). The Brazilian version of the questionnaire was valid and reliable for assessing knowledge regarding child abuse by Portuguese-speaking dentists.

Translation and validation of the Greek chronic liver disease questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available AIM: To translate into Greek and validate the chronic liver disease questionnaire (CLDQ).METHODS: Two hundred and six consecutive adult patients with the diagnosis of a chronic liver disease from 2 general hospitals in Athens were enrolled in the study from May to September 2008. In order to assess their quality of life (QOL) the CLDQ was applied. The instrument was translated from English, back translated and reviewed in focus groups within the framework of a large multicenter study. The measurements that were performed included: 2 independent sample t tests, one-way analysis of variance, reliability coefficients, explanatory factor analysis using a varimax rotation and the principal components method.RESULTS: One hundred and twenty five (61%) patients were men, half were aged 40-59 years and > 33% were > 60 years old. Among the patients, 48 (23%) were hospitalized and 97 (47%) were cirrhotic according to the Child-Pugh score. The internal consistency of the Greek CLDQ version using Cronbach’s alpha coefficient was found to be 0.93. Exploratory factor analysis identified 7 domains accounting for 65% of the variance of CLDQ items and only partially overlapping with those found in the original version. The area under the receiver operating characteristics curve was calculated at 0.813 and the logistic estimate for the threshold score of 167.50 provided a sensitivity of 74.3% and a specificity of 71.6% for the model.CONCLUSION: Our data confirmed the validity of the Greek version of the CLDQ in identifying the QOL among patients with chronic liver disease.

The validity of the Nordic patient safety culture questionnaire (TUKU).  

UK PubMed Central (United Kingdom)

BACKGROUND: Patient safety culture (PSC) has been postulated to have a significant influence on the quality of health care. OBJECTIVE: This study aims to evaluate the psychometric properties of the TUKU PSC questionnaire. METHODS: The questionnaire development was based on the view that patient safety constitutes not only the absence of adverse events, but also the presence of certain organizational attributes that enable safety. The TUKU questionnaire has two parts: a measure of psychological dimensions, and a measure of employees' perceptions of organizational functions. The TUKU questionnaire was validated using a sample of 1162 health care professionals from seven Finnish health care organizations. Two studies were carried out, one focusing on construct validity and the other on criterion validity. RESULTS: Regarding construct validity, the empirical model matched the theory quite well. The results of Study 2 concerning criterion validity were more ambiguous. Four of the organizational dimensions and two of the psychological dimensions were related to patient safety incidents occurring 16 months after administering the questionnaire. CONCLUSIONS: The study provided evidence on the key organizational dimensions that comprise patient safety culture and affect patient safety. The study further contributed towards validation of an instrument for measuring these dimensions.

Abbreviated Psychologic Questionnaires Are Valid in Patients With Hand Conditions.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Pain Catastrophizing Scale (PCS) and Short Health Anxiety Inventory (SHAI) can help hand surgeons identify opportunities for psychologic support, but they are time consuming. If easier-to-use tools were available and valid, they might be widely adopted. QUESTIONS/PURPOSES: We tested the validity of shorter versions of the PCS and SHAI, the PCS-4 and the SHAI-5, by assessing: (1) the difference in mean scaled scores of the short and long questionnaires; (2) floor and ceiling effects between the short and long questionnaires; (3) correlation between the short questionnaires and the outcome measures (an indication of construct validity); and (4) variability in disability and pain, between the short and long questionnaires. METHODS: One hundred sixty-four new or followup adult patients in one hand surgery clinic completed the SHAI-18, SHAI-5, PCS-13, PCS-4, Patient Health Questionnaire (PHQ)-9, PHQ-2, DASH, and QuickDASH questionnaires, and an ordinal pain scale, as part of a prospective cross-sectional study. Mean scores for the short and long questionnaires were compared with paired t-tests. Floor and ceiling effects were calculated. Pearson's correlation was used to assess the correlation between the short and long questionnaires and with outcome measures. Regression analyses were performed to find predictors of pain and disability. RESULTS: There were small, but significant differences between the mean scores for the DASH and QuickDASH (QuickDASH higher), SHAI-18 and SHAI-5 (SHAI-18 higher), and PCS-13 and PCS-4 (PCS-4 higher), but not the PHQ-9 and PHQ-2. Floor effects ranged between 0% and 65% and ceiling effects between 0% and 3%. There were greater floor effects for the PHQ-2 than for the PHQ-9, but floor and ceiling effects were otherwise comparable for the other short and long questionnaires. All questionnaires showed convergent and divergent validity and criterion validity was shown in multivariable analyses. CONCLUSIONS: Content validity, construct convergent validity, and criterion validity were established for the short versions of the PCS and SHAI. Using shorter forms creates small differences in mean values that we believe are unlikely to affect study results and are more efficient and advantageous because of the decreased responder burden. LEVEL OF EVIDENCE: Level III, diagnostic study. See Instructions for Authors for a complete description of levels of evidence.

[Validation of a questionnaire of lycopene frequency intake].  

UK PubMed Central (United Kingdom)

INTRODUCTION: An inverse relationship between some chronic degenerative diseases and plasma lycopene levels has been demonstrated. Dietary intake questionnaires are one of the current methods most used to ascertain dietary patterns and explore their association with the disease risk. The main drawback of their use is the need for previous validation. The purpose of this study was to validate a frequency questionnaire in order to assess the intake of licopene, in the population of the Canary Islands. METHODS: A food intake frequency questionnaire was designed and administered to 70 patients of the Plastic Surgery Service of the Hospital Universitario Insular de Gran Canaria. Estimated lycopene intake from the food intake frequency questionnaire was examined in relation to plasma lycopene levels, measured by HPLC. RESULTS: The Spearman correlation coefficient between estimated lycopene intake and plasma levels was 0,421 and the validity of the questionnaire was demonstrated. Furthermore, an association between obesity and some pathologies with plasma lycopene levels was observed, although not statistically significant. CONCLUSIONS: The food intake frequency questionnaire is valid and it could be useful in epidemiological studies in the population of the Canary Islands.

Validation of a French version of the Oxford knee questionnaire.  

UK PubMed Central (United Kingdom)

INTRODUCTION: Self-administered quality-of-life questionnaires are a valuable evaluation tool in orthopedic surgery to determine patient satisfaction. The Oxford knee questionnaire has been validated for osteoarthritic patients. The aim of this study was to validate a French version of this English form. One hundred patients waiting for knee replacement were selected. The answers to the questionnaire were analysed and compared to the clinical and functional International Knee Society score (IKS). HYPOTHESIS: There is negative correlation between the results of the Oxford knee questionnaire and the IKS score. RESULTS: None of the patients had difficulty understanding the questions. The mean Oxford knee score was 43.7 (range 21-56, SD 6.9). The distribution was considered normal. There was no floor effect (0%); there was a limited ceiling effect (7%). The internal consistency of the questionnaire was excellent. There was a negative correlation between the Oxford knee score and the IKS knee score, functional score and global score. DISCUSSION: Our results are very similar to the results from the normative English version of the knee questionnaire and to the results from translated questionnaires in other foreign languages. Our French adaptation of the Oxford knee questionnaire can be used to measure the global function of a patient before knee replacement as accurately as the original English version. It is self-administered, easy to use and patients can send their responses by post, which makes it a useful tool for the routine evaluation of patients before knee replacement.

Development and Validation of Caregivers Perspectives Questionnaire in Comatose Patients  

Directory of Open Access Journals (Sweden)

Full Text Available The caregivers perspective about care in comatose patients is different among different caregivers, and thus the question is how it is perceived by caregivers. Among the health staff and family members, perspective of caring is obviously different. Thus, the current study was carried out to develop a valid and reliable instrument to assess of caregivers perspective in comatose patient care. For gathering the data used from the questionnaire consisted of items of Van Manens hermeneutic phenomenology, then these items combined and validated by content, face and construct validity and by split half and Cronbach a coefficient for reliability. The results showed that the four factors were labeled living with client, efforts for survival, professional conscience and responsibility and respect of human dignity.

[The assessment of reliability and validity of musculoskeletal questionnaire].  

UK PubMed Central (United Kingdom)

OBJECTIVE: To evaluate the reliability and validity of musculoskeletal questionnaire. METHODS: A self-administered modified musculoskeletal questionnaire was used to investigate 12 098 workers from eight occupations, i.e. coal mining, petroleum, metallurgical, mechanical manufacturing, chemical, garment and railroad transportation industries and education. The Cronbach's ? coefficient, analysis of covariance and multiple logistic regression were used to assess the reliability and validity of musculoskeletal questionnaire. RESULTS: The consistent test between total items of Musculoskeletal Questionnaire and each factor showed that the range of Cronbach's ? was 0.52 ? 0.92, except from vibration factor, other Cronbach's ? was more than 0.7. All 55 items of Musculoskeletal Questionnaire were subjected to factor analysis, and ten latent factors were identified, which explained 55.17% of the total variance. The potentially hazardous working conditions could be categorized into seven dimensions (force, dynamic load, static load, repetitive load, climate factors, vibration exposure and environmental ergonomic factor), which consisted with the theory model. The results of covariance analysis indicated that there were significant difference among 7 dimension indices in different jobs (P < 0.01). CONCLUSION: The modified Musculoskeletal Questionnaire is a valid and reliable tool for measuring musculoskeletal workload.

UK PubMed Central (United Kingdom)

The purpose of this study was to validate the Caregiver Mealtime and Dysphagia Questionnaire (CMDQ). The validation procedures included the following: (a) assessment of internal consistency reliability, (b) testing of approximations to normality, and (c) assessments of convergent and discriminant validity. Study participants were 85 noncompliant and 50 compliant caregivers. Factor analytical techniques revealed three interpretable scales: Quality of Life (QOL), Disagreement with the SLP (DSLP), and Avoidance (AV). All scales were internally consistent. The QOL and DSLP scales showed evidence of convergent and discriminant validity. The AV scale evidenced a floor effect, limiting its discriminating power.

Validity of the Danish Prostate Symptom Score questionnaire in stroke  

DEFF Research Database (Denmark)

Objective – To determine the content and face validity of the Danish Prostate Symptom Score (DAN-PSS-1) questionnaire in stroke patients. Materials and methods – Content validity was judged among an expert panel in neuro-urology. The judgement was measured by the content validity index (CVI). Face validity was indicated in a clinical sample of 482 stroke patients in a hospital-based, cross-sectional survey. Results – I-CVI was rated >0.78 (range 0.94–1.00) for 75% of symptom and bother items corresponding to adequate content validity. The expert panel rated the entire DAN-PSS-1 questionnaire highly relevant (S-CVI = 1.00). No experts suggested items omitted or improved. The response rate was 84% and face validity had an acceptable level of completed response for each symptom items (96–98%) and bother items (93–96%) indicating that all items were well interpreted. Conclusion – The DAN-PSS-1 questionnaire appears to be content and face valid for measuring lower urinary tract symptoms after stroke.

Validation of a questionnaire of knowledge about asthma  

International Nuclear Information System (INIS)

An educative intervention destined to increase the knowledge in asthma allows the children and/or its parents to acquire abilities that allow to prevent and/or to handle the asthmatic attacks, decreasing the morbidity produced by the disease, nevertheless we do not account with a validated instrument that allows us to quantify the level of asthma knowledge. The objective is to develop and to validate a questionnaire of knowledge about asthma to be filled out by the parents and/or people in charge of the care of the asthmatic pediatric patients. The 17 items that conform the questionnaire were obtained alter literature review, realization of focal groups the professional experience of the investigators and the realization of pilot studies. The face content and concurrent validity of the instrument was evaluated; we also determined the factor structure, test-retest reproducibility, and sensitivity to change of the questionnaire. We included 120 patients with average age of 4.5 %3.7 years the factor analysis demonstrated a probable structure of three factors that altogether explain 85% of the total variance of the results the face and content validity was based on the concept of a multi-disciplinary group of experts in the field the concurrent validity was demonstrated by the ability of the questionnaire to distinguish low from high knowledge parents. Test-retest reproducibility and sensitivity to change were demonstrated comparing scores of the questionnaire filled out in two different occasions. The questionnaire of knowledge of asthma developed in the study is a useful and reliable tool to quantify the basal level of asthma knowledge in parents of asthmatic children and to determine the effectiveness of an educative intervention destined to increase the knowledge and understanding of the disease.

The Spanish Linguistic Validation of the Ureteral Stent Symptom Questionnaire.  

UK PubMed Central (United Kingdom)

Purpose: Ureteric Stent Symptoms Questionnaire (USSQ) is an intervention specific Health related Quality of Life (HrQoL) measure. We describe development and validation of the Spanish version. Materials and Methods: We followed established methods to develop Spanish version of the original USSQ. After pilot testing we conducted formal validation studies; 70 patients, undergoing placement of ureteric stents, successfully completed the Spanish USSQ as well as EuroQOL- 5D (male and female), the ICIQ male and female LUTS questionnaires at weeks 1 and 4 after stent insertions, and at week 4 after their removal. In addition, 40 healthy people acted as control group and completed the same questionnaires twice at 3 weeks of interval. Statistical analyses were performed to evaluate reliability, validity and sensitivity to change of the Spanish USSQ. Results: After revision of the initial two drafts following translation, back translation and pilot testing, a final draft was developed that underwent field testing. Psychometric analyses revealed satisfactory internal consistencies (Cronbach alpha coefficients: 0.73-0. 85) and test-retest reliability (Spearman correlation coefficient: > 0.6) for the domains of urinary symptom, body pain, and general health. It demonstrated satisfactory discriminant validity (Sensitivity to change, p<0.01), convergent validity (good correlations between the domains of the USSQ and existing validated questionnaires) and test-retest reliability (p<0.001). Analysis of the domains of the sexual matter (21.4%) and work performance (35.7%), were limited due to small proportion of the study population in whom it was applicable. Conclusions: Results of our development and validation study demonstrate that the new Spanish version of the USSQ is a psychometrically valid intervention specific measurer for use in the second commonest language in the world. It is a reliable outcome measure that could be used for both clinical and research purposes.

Construction and Validation of Attitudes Toward Plagiarism Questionnaire  

Science.gov (United States)

Aim To develop and test the psychometric characteristics of a questionnaire measuring attitudes toward plagiarism. Methods Participants were 227 undergraduates and graduate students from three Croatian universities, with a median age of 21 years (range 18 to 48). Research was conducted from March to June 2009. For the purpose of construction of the first version of the questionnaire, 67 statements (items) were developed. The statements were based on the relevant literature and were developed following rules and recommendations for questionnaire writing, and 36 items were chosen for final validation. Factor analysis was used to find out the factor structure of the questionnaire and to measure construct validity. Results The final version of the questionnaire consisted of 29 items divided into a three-factor structure: factor I – positive attitude toward plagiarism (12 items); factor II – negative attitude toward plagiarism (7 items); and factor III – subjective norms toward plagiarism (10 items). Cronbach ? was calculated to confirm the reliability of the scale: factor I – ??=?0.83; factor II – ??=?0.79; and factor III – ??=?0.85. Correlations between factors were: -0.37 between I and II, -0.41 between I and III, and +0.31 between II and III. Conclusion Attitudes Toward Plagiarism questionnaire was developed, with good psychometric characteristics. It will be used in future research as a standardized tool for measuring attitudes toward plagiarism.

Development and validation of a salt knowledge questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: Initiatives promoting the reduction of high-salt food consumption by consumers need to be partly based on current levels of salt knowledge in the population. However, to date there is no validated salt knowledge questionnaire that could be used to assess population knowledge about dietary salt (i.e. salt knowledge). Therefore, the aim of the present study was to develop and validate a salt knowledge questionnaire. DESIGN: A cross-sectional study was conducted on an online web survey platform using convenience, snowball sampling. The survey questionnaire was evaluated for content and face validity before being administered to the respondents. SETTING: Online survey. SUBJECTS: A total of forty-one nutrition experts, thirty-two nutrition students and thirty-six lay people participated in the study. RESULTS: Item analyses were performed to evaluate the psychometric properties of the test items. Twenty-five items were retained to form the final set of questions. The total scores of the experts were higher than those of the students and lay people (P < 0·05). The total salt knowledge score showed significant correlations with use of salt at the table (? = -0·197, P < 0·05) and inspection of the salt content in food products when shopping (? = 0·400; P < 0·01). CONCLUSIONS: The questionnaire demonstrated sufficient evidence of construct validity and internal consistencies between the items. It is likely to be a useful tool for the evaluation and measurement of levels of salt knowledge in the general population.

The Groningen Radiotherapy-Induced Xerostomia questionnaire: Development and validation of a new questionnaire  

International Nuclear Information System (INIS)

Purpose: The purpose of this study was to develop and validate a questionnaire (Groningen Radiotherapy-Induced Xerostomia (GRIX) questionnaire) that has the ability to distinguish between patient-rated xerostomia during day and night and can be used to evaluate the impact of emerging radiation delivery techniques aiming at prevention of xerostomia in more detail. Materials and methods: All questions in the GRIX were generated from an exhaustive list of relevant questions according to xerostomia as reported in the literature and reported by patients and health care providers. Finally the GRIX was reduced from 56 questions to a 14-item questionnaire, with four subscales; xerostomia during day and night and sticky saliva during day and night. 315 patients filled out 2936 questionnaires and the GRIX was evaluated by calculating Crohnbach's ? for all subscales. Criterion validity was evaluated to compare the GRIX with patient-rated xerostomia scored with the EORTC QLQ-HN35 and physician-rated xerostomia, test-retest analysis and responsiveness were also tested. Results: Crohnbach's ? varied for all subscales between 0.88 and 0.94. The GRIX scored well for criterion-related validity on all subscales with high correlations with the EORTC QLQ-HN35 xerostomia and sticky saliva scale as well with physician-rated toxicity scoring. No significant differences were found between test and retest score and the GRIX showed good responsiveness with different time points for all subscales. Conclusion: The GRIX is a validated questionnaire which can be used in future research focusing on patient-rated xerostomia and sticky saliva during day and night in relation with the impact of emerging radiation delivery techniques aiming at reduction of xerostomia.

Validation of the Korean Integrative Medicine Attitude Questionnaire (IMAQ).  

UK PubMed Central (United Kingdom)

BACKGROUND: To develop a Korean version of the Integrative Medicine Attitude Questionnaire (IMAQ) in order to evaluate physician attitudes toward integrative medicine/complementary and alternative medicine (CAM). METHODS: We developed a Korean IMAQ through careful translation of the 28-item questionnaire developed by Schmidt et al. A web-based survey was sent via email to 118 primary care physicians in Korea. The complete respose rate wasa 52.5%. The questionnaire's reliability and validity were verified using Cronbach's ?, factor analysis, and discriminant analysis. RESULTS: Although the Korean IMAQ exhibited excellent internal consistency, its validity was insufficient. Our results suggest that Western and Korean physicians may have different understandings of CAM and the concept of holism, as factor analysis showed that incorrectly classified items were mainly part of the holism conceptual domain. Furthermore, the sum of the items within the holism conceptual domain was not significantly different for physicians who had previously received CAM education. CONCLUSION: This study developed and tested the first Korean IMAQ. We found that this version of the questionnaire lacks sufficient validity and requires further modification.

Examining the ecological validity of the Talent Development Environment Questionnaire.  

UK PubMed Central (United Kingdom)

It is clear that high class expertise and effective practice exists within many talent development environments across the world. However, there is also a general consensus that widespread evidence-based policy and practice is lacking. As such, it is crucial to develop solutions which can facilitate effective dissemination of knowledge and promotion of evidence-based talent development systems. While the Talent Development Environment Questionnaire (Martindale et al., 2010 ) provides a method through which this could be facilitated, its ecological validity has remained untested. As such, this study aimed to investigate the real world applicability of the questionnaire through discriminant function analysis. Athletes across ten distinct regional squads and academies were identified and separated into two broad levels, 'higher quality' (n = 48) and 'lower quality' (n = 51) environments, based on their process quality and productivity. Results revealed that the Talent Development Environment Questionnaire was able to discriminate with 77.8% accuracy. Furthermore, in addition to the questionnaire as a whole, two individual features, 'quality preparation' (P < 0.01) and 'understanding the athlete' (P < 0.01), were found to be significant discriminators. In conclusion, the results indicate robust structural properties and sound ecological validity, allowing the questionnaire to be used with more confidence in applied and research settings.

Validation of a persian version of motorcycle rider behavior questionnaire.  

UK PubMed Central (United Kingdom)

In Iran, road traffic injuries are the first cause of burden of disease and motorcyclists are the most vulnerable road users. Elliot and colleagues developed the "Motorcycle Rider Behavior Questionnaire" (MRBQ), on the basis of Reason's "Driver Behavior Questionnaire" (DBQ) in 2007. The purpose of this study was to assess the validity and reliability of a Persian version of MRBQ. The 43-item MRBQ was adapted to Persian according to translation-back translation method. The questionnaire was significantly revised after assessment of content validity. In the revised version, 10 items of original MRBQ were deleted and 15 new items were added. The revised MRBQ was used in a survey of 518 motorcyclists. To assess the construct validity of MRBQ, we used Buss-Perry Aggression questionnaire concurrently on all of the subjects. After three weeks, we carried out the retest study on 119 out of 518 subjects. The mean age of the subjects was 32.5 years (SD=8.8). All of the participants were male with mean of 9.3 years of motorcycle riding experience (SD=7.3). Principal Components Analysis (PCA) showed six subscales: "Speed Violations", "Traffic Errors", "Safety Violations", "Traffic Violations", "Stunts" and "Control Errors", which accounted for 36.44% of total variance together. For each of these subscales, Cronbach's Alpha was between 0.79 to 0.91. Intraclass Correlation Coefficient for six subscales and total questionnaire were from 0.73 to 0.91. There were significant correlations between MRBQ subscales and subscales of Buss-Perry aggression questionnaire. The results indicated that the 48-item Persian version of MRBQ is a suitable measure for studying motorcyclists' behavior.

Validation of a questionnaire measuring the regulation of autonomic function  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background To broaden the range of outcomes that we can measure for patients undergoing treatment for oncological and other chronic conditions, we aimed to validate a questionnaire measuring self-reported autonomic regulation (aR), i.e. to characterise a subject's autonomic functioning by questions on sleeping and waking, vertigo, morningness-eveningness, thermoregulation, perspiration, bowel movements and digestion. Methods We administered the questionnaire to 440 participants (?: N = 316, ?: N = 124): 95 patients with breast cancer, 49 with colorectal cancer, 60 with diabetes mellitus, 39 with coronary heart disease, 28 with rheumatological conditions, 32 with Hashimoto's disease, 22 with multiple morbidities and 115 healthy people. We administered the questionnaire a second time to 50.2% of the participants. External convergence criteria included the German version of the Hospital Anxiety and Depression Scale (HADS-D), a short questionnaire on morningness-eveningness, the Herdecke Quality of Life Questionnaire (HLQ) and a short version questionnaire on self-regulation. Results A principal component analysis yielded a three dimensional 18-item inventory of aR. The subscales orthostatic-circulatory, rest/activity and digestive regulation had internal consistency (Cronbach-?: r? = 0.65 – 0.75) and test-retest reliability (rrt = 0.70 – 85). AR was negatively associated with anxiety, depression, and dysmenorrhoea but positively correlated to HLQ, self-regulation and in part to morningness (except digestive aR) (0.49 – 0.13, all p Conclusion An internal validation of the long-version scale of aR yielded consistent relationships with health versus illness, quality of life and personality. Further studies are required to clarify the issues of external validity, clinical and physiological relevance.

Validation of a chronotype questionnaire including an amplitude dimension.  

Science.gov (United States)

The aim of this paper was to validate a French version of the Chronotype Questionnaire (Ogi?ska, 2011, Pers. Individ. Dif. 50:1039-1043), which represents an interesting novelty in the psychometric assessment of chronotype, because it comprises not only an assessment of the morningness-eveningness (ME) dimension, but also a distinctness (DI) dimension (i.e., amplitude), which represents the range of diurnal variation. In study 1, we aimed to confirm the structure of the Chronotype Questionnaire, with two different samples, young adults (n = 338, mean ± SD = 18.70 ± 1.12 yrs, 244 men and 94 women) and old adults (n = 477, mean ± SD = 55.92 ± 11.9 yrs, 168 men and 310 women). The confirmatory factor analysis (CFA) indicated a poor fit in both samples as well as in the whole sample, which could be due to some inconsistencies in the original instrument, above all in the distinctness dimension. We therefore decided to revise the Chronotype Questionnaire, keeping the ME dimension, but refining the DI dimension. In study 2, with a new sample of 197 participants (mean ± SD = 22.71 ± 2.23 yrs, 105 men and 92 women), we examined the factor structure of the revised scale containing 18 items. The resulting questionnaire contained 16 items (i.e., 8 items on each scale), with item factor loadings higher than .45. In study 3, we aimed to confirm the factor structure of the instrument developed in study 2 as well as to examine its convergent validity, with a new sample of 158 participants (mean ± SD = 55.92 ± 11.9 yrs, 97 men and 61 women). Results of the CFA showed that a good fit of the model could be obtained with 16 items in the questionnaire. The new questionnaire derived from the original Chronotype Questionnaire was from now on called the Caen Chronotype Questionnaire (CCQ). Convergence validity was obtained with the Horne and Östberg questionnaire and the ME scale of the CCQ, showing a negative significant relationship (r = -.82). The CCQ showed promising psychometric qualities, and further research should aim to combine it with physiological variables. PMID:23510464

Validation of the folate food frequency questionnaire in vegetarians.  

UK PubMed Central (United Kingdom)

Adequate folate status has an important role in the prevention of chronic and developmental diseases and is considered a potential public health issue. Therefore, valid tools for measuring the vitamin intake are needed. In our previous study a folate food frequency questionnaire (FFQ) designed to measure dietary folate equivalents was developed and validated among adult women against serum and erythrocyte (red blood cell) folate and plasma homocysteine. The aim of the present study was to validate the FFQ in vegetarians (n=75). The Pearson correlation for folate intake and biomarkers was 0.41, 0.36 and -0.15 for serum and red blood cell folate and plasma homocysteine, respectively. The quadratic weighted kappa value for biomarkers was above 0.2 and the gross misclassification of subjects into quartiles was less than 10%. The FFQ is a valid tool for measuring dietary folate equivalent intake in Croatian vegetarians.

Development and Validation of the Social Emotional Competence Questionnaire (SECQ)  

Directory of Open Access Journals (Sweden)

Full Text Available Reliable and valid measures of children's and adolescents' social emotional competence (SEC) are necessary to develop in order to assess their social emotional development and provide appropriate intervention in child and adolescent development. A pool of 25 items was created for the Social Emotional Competence Questionnaire (SECQ) that represented five dimensions of SEC: self-awareness, social awareness, self-management, relationship management and responsible decision-making. A series of four studies are reported relating to the development and validation of the measure. Confirmatory factor analyses of the responses of 444 fourth-graders showed an acceptable fit of the model. The model was replicated with another 356 secondary school students. Additional studies revealed good internal consistency. The significant correlations among the five SEC components and academic performance provided evidence for the predictive validity of the instrument. With multiple samples, these results showed that the scale holds promise as a reliable, valid measure of SEC.

The WHO Quality of Life (WHOQOL) Questionnaire: Danish validation study.  

UK PubMed Central (United Kingdom)

The objective of this pilot study was to evaluate the Danish translation of the WHO Quality of Life Questionnaire, the WHOQOL, by means of the psychometric properties of the Danish version. The translation method followed the WHO standard procedures, including forward and backward translation, focus group discussions, and assessment of response choice weighting through visual analogue scales. In the study we evaluated the applicability of the WHOQOL in patients with physical and mental disorders compared with a sample of healthy controls. The WHOQOL was compared with health-related quality of life questionnaire SF36 (Short Form 36). The internal consistency or homogeneity of the Danish WHOQOL was found adequate, and its applicability and its performance in distinguishing between population groups were satisfactory. The abbreviated version of WHOQOL-100, the WHOQOL-BREF, was analysed separately and was also found psychometrically valid. The WHOQOL is a questionnaire that is easy to administer, and it seems applicable for use.

Validation of the Adolescent Meta-cognition Questionnaire Version  

Directory of Open Access Journals (Sweden)

Full Text Available Background: The role and importance of meta-cognitive beliefs in creating and retaining of anxiety disorders were explained initially in meta-cognitive theory. The purpose of this study was to validate the Meta-cognitions Questionnaire-Adolescent version (MCQ-A) in normal Iranian people and compare of meta-cognitive beliefs between adolescents with anxiety disorders and normal individuals.Materials and Method: This was a standardized study. First of all, the original version was translated into Persian then administered to 204 (101 boys and 103 girls) adolescent aged 13 through 17 years. Theyhave been clustered randomly. They were selected from the schools of Isfahan, together with mood and feelings questionnaire and revised children's manifest anxiety scale. In order to assess reliability, method of internal consistency (Chronbach’s alpha and split-half coefficient) was used, and also in order to assess validity, convergent validity, criterion validity and confirmatory factor analysis were used. Results: The results of correlation coefficient of convergent validity showed a relation between total score of (MCQ-A) and its components with anxiety and depression except cognitive self-consciousness. Data were indicative of appropriate level of Coranbach’s alpha and split-half reliability coefficients of the MCQ-A and extracted factors. The results of factor analysis by principle components analysis and using varimax rotation showed 5 factors that account for 0.45% of the variance. Conclusion: MCQ-A has satisfactory psychometric properties in Iranian people

Validation of Italian version of Brace Questionnaire (BrQ).  

UK PubMed Central (United Kingdom)

BACKGROUND: Brace questionnaire (BrQ) is a tool used to evaluate Health Quality of Life (HRQoL) in patients with Adolescent Idiopathic Scoliosis (AIS) that undergo bracing treatment. The BrQ has not been translated and validated for Italian-speaking patients with AIS. The aim of the study was to perform a trans-cultural validation of BrQ to be used in an Italian speaking population. METHODS: Translation into Italian (I-BrQ) and back translation to the original Greek (G-BrQ) was performed. The final I-BrQ was then analyzed for Italian cultural characteristics and no inconsistencies were found. After that, construct validity was measured analyzing the I-BrQ relationship with 1) Scoliosis Research Society-22 patient Questionnaire (SRS-22), in order to evaluate the relationship with another patient-oriented questionnaire not focused on brace therapy; 2) Cobb degree scale, in order to evaluate the relationship with the magnitude of the curve. Reproducibility was also tested. RESULTS: Translation of the G-BrQ into Italian was successful and back-translation to Greek corresponded well with the original Greek version.Global I-BrQ correlated strongly with SRS-22 (r = 0.826; p < 0.001). Almost all sub scores from each I-BrQ domain strongly correlated with the single domain scores of SRS-22. Only two I-BrQ sub scores weakly inversely correlated with Cobb degree value.Reproducibility was good (Spearman-Brown coefficient value was 0.943; p < 0.05). CONCLUSIONS: Trans-cultural validation in Italian language showed the validity and reliability of the I-BrQ.

The Selective Mutism Questionnaire: Measurement Structure and Validity  

Science.gov (United States)

Objective To evaluate the factor structure, reliability, and validity of the 17-item Selective Mutism Questionnaire. Method Diagnostic interviews were administered via telephone to 102 parents of children identified with selective mutism (SM) and 43 parents of children without SM from varying U.S. geographic regions. Children were between the ages of 3 and 11 inclusive and comprised 58% girls and 42% boys. SM diagnoses were determined using the Anxiety Disorders Interview Schedule for Children - Parent Version (ADIS-C/P); SM severity was assessed using the 17-item Selective Mutism Questionnaire (SMQ); and behavioral and affective symptoms were assessed using the Child Behavior Checklist (CBCL). An exploratory factor analysis (EFA) was conducted to investigate the dimensionality of the SMQ and a modified parallel analysis procedure was used to confirm EFA results. Internal consistency, construct validity, and incremental validity were also examined. Results The EFA yielded a 13-item solution consisting of three factors: a) Social Situations Outside of School, b) School Situations, and c) Home and Family Situations. Internal consistency of SMQ factors and total scale ranged from moderate to high. Convergent and incremental validity were also well supported. Conclusions Measure structure findings are consistent with the 3-factor solution found in a previous psychometric evaluation of the SMQ. Results also suggest that the SMQ provides useful and unique information in the prediction of SM phenomenon beyond other child anxiety measures.

Environmental education curriculum evaluation questionnaire: A reliability and validity study  

Science.gov (United States)

The intention of this research project was to bridge the gap between social science research and application to the environmental domain through the development of a theoretically derived instrument designed to give educators a template by which to evaluate environmental education curricula. The theoretical base for instrument development was provided by several developmental theories such as Piaget's theory of cognitive development, Developmental Systems Theory, Life-span Perspective, as well as curriculum research within the area of environmental education. This theoretical base fueled the generation of a list of components which were then translated into a questionnaire with specific questions relevant to the environmental education domain. The specific research question for this project is: Can a valid assessment instrument based largely on human development and education theory be developed that reliably discriminates high, moderate, and low quality in environmental education curricula? The types of analyses conducted to answer this question were interrater reliability (percent agreement, Cohen's Kappa coefficient, Pearson's Product-Moment correlation coefficient), test-retest reliability (percent agreement, correlation), and criterion-related validity (correlation). Face validity and content validity were also assessed through thorough reviews. Overall results indicate that 29% of the questions on the questionnaire demonstrated a high level of interrater reliability and 43% of the questions demonstrated a moderate level of interrater reliability. Seventy-one percent of the questions demonstrated a high test-retest reliability and 5% a moderate level. Fifty-five percent of the questions on the questionnaire were reliable (high or moderate) both across time and raters. Only eight questions (8%) did not show either interrater or test-retest reliability. The global overall rating of high, medium, or low quality was reliable across both coders and time, indicating that the questionnaire can discriminate differences in quality of environmental education curricula. Of the 35 curricula evaluated, 6 were high quality, 14 were medium quality and 15 were low quality. The criterion-related validity of the instrument is at current time unable to be established due to the lack of comparable measures or a concretely usable set of multidisciplinary standards. Face and content validity were sufficiently demonstrated.

Cognitive processing and acrophobia: validating the Heights Interpretation Questionnaire.  

Science.gov (United States)

Three studies were conducted to examine the psychometric properties of a new scale: the Heights Interpretation Questionnaire (HIQ). This scale was designed to measure height fear-relevant interpretation bias to help assess the relationship between biased interpretations and acrophobia symptoms. Studies 1 (N=553) and 2 (N=308) established the scale's factor structure and convergent and discriminant validity among two large undergraduate samples. Study 3 (N=48) evaluated the predictive validity of the HIQ by examining how well the scale predicted subjective distress and avoidance on actual heights. Factor analysis resulted in four distinct factors, and results suggest that each of the factors, along with the full HIQ, have good reliability and validity. Additionally, the scale predicts subjective distress and avoidance on heights beyond self-reported acrophobia symptoms. Overall, the HIQ shows promise as a new tool to investigate cognitive processing biases in acrophobia. PMID:21641766

Reliability and validity of the neurorehabilitation experience questionnaire for inpatients.  

UK PubMed Central (United Kingdom)

BACKGROUND: Patient-centered measures of the inpatient neurorehabilitation experience are needed to assess services. OBJECTIVE: The objective of this study was to develop a valid and reliable Neurorehabilitation Experience Questionnaire (NREQ) to assess whether neurorehabilitation inpatients experience service elements important to them. METHODS: Based on the themes established in prior qualitative research, adopting questions from established inventories and using a literature review, a draft version of the NREQ was generated. Focus groups and interviews were conducted with 9 patients and 26 staff from neurological rehabilitation units to establish face validity. Then, 70 patients were recruited to complete the NREQ to ascertain reliability (internal and test-retest) and concurrent validity. RESULTS: On the basis of the face validity testing, several modifications were made to the draft version of the NREQ. Subsequently, internal reliability (time 1 ? = .76, time 2 ? = .80), test retest reliability (r = 0.70), and concurrent validity (r = 0.32 and r = 0.56) were established for the revised version. Whereas responses were associated with positive mood (r = 0.30), they appeared not to be influenced by negative mood, age, education, length of stay, sex, functional independence, or whether a participant had been a patient on a unit previously. CONCLUSIONS: Preliminary validation of the NREQ suggests promise for use with its target population.

Validity of the occupational sitting and physical activity questionnaire.  

UK PubMed Central (United Kingdom)

PURPOSE: Sitting at work is an emerging occupational health risk. Few instruments designed for use in population-based research measure occupational sitting and standing as distinct behaviors. This study aimed to develop and validate brief measure of occupational sitting and physical activity. METHODS: A convenience sample (n = 99, 61% female) was recruited from two medium-sized workplaces and by word-of-mouth in Sydney, Australia. Participants completed the newly developed Occupational Sitting and Physical Activity Questionnaire (OSPAQ) and a modified version of the MONICA Optional Study on Physical Activity Questionnaire (modified MOSPA-Q) twice, 1 wk apart. Participants also wore an ActiGraph accelerometer for the 7 d in between the test and retest. Analyses determined test-retest reliability with intraclass correlation coefficients and assessed criterion validity against accelerometers using the Spearman ?. RESULTS: The test-retest intraclass correlation coefficients for occupational sitting, standing, and walking for OSPAQ ranged from 0.73 to 0.90, while that for the modified MOSPA-Q ranged from 0.54 to 0.89. Comparison of sitting measures with accelerometers showed higher Spearman correlations for the OSPAQ (r = 0.65) than for the modified MOSPA-Q (r = 0.52). Criterion validity correlations for occupational standing and walking measures were comparable for both instruments with accelerometers (standing: r = 0.49; walking: r = 0.27-0.29). CONCLUSIONS: The OSPAQ has excellent test-retest reliability and moderate validity for estimating time spent sitting and standing at work and is comparable to existing occupational physical activity measures for assessing time spent walking at work. The OSPAQ brief instrument measures sitting and standing at work as distinct behaviors and would be especially suitable in national health surveys, prospective cohort studies, and other studies that are limited by space constraints for questionnaire items.

Polish adaptation and validation of the Agoraphobic Cognitions Questionnaire and the Body Sensations Questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Aim. The present study aimed at the adaptation and validation of two questionnaires assessing fear of bodily sensations (BSQ; suggested Polish name: Kwestionariusz Dozna? Cielesnych [KDC]) and concerns specific to agoraphobics (ACQ; suggested Polish name: Kwestionariusz My?li Towarzysz?cych Agorafobii [KMTA]).Method. The study included a total of 82 patients diagnosed with agoraphobia or panic disorder with agoraphobia according to the diagnostic criteria of the DSM-IV as well as 100 control subjects who did not show the presence of mental disorders.Results. The results showed that both adapted questionnaires meet basic psychometric criteria. The Polish-language versions of the ACQ and BSQ are characterized by a high content validity, internal consistency and showed to be stable over a period of 28 days. Moreover, the factor structure of the Polish version of the ACQ showed to be highly similar to the original version.Conclusions Polish-language versions of the ACQ and BSQ have been found to be reliable and valid research and diagnostic instruments for the assessment of fear for bodily sensations and agoraphobic cognitions. Due to their high efficiency and adequate psychometric characteristics these measures might be very useful in research as well as in the diagnosis and evaluation of therapeutic effects.

Development and validation of the smoking abstinence expectancies questionnaire.  

UK PubMed Central (United Kingdom)

INTRODUCTION: Despite evidence that expectancies influence the use and effects of drugs, there are no questionnaires that assess abstinence expectancies among smokers. Such a questionnaire may assist prediction models of successful quitting, enable clinicians to target specific expectancies, and give researchers a broader understanding of cognitive processes that influence smoking. METHODS: We aimed to develop a questionnaire that assesses, among daily smokers, expected short-term psychological and physiological consequences to (hypothetically) abstaining from smoking. Initial scale items, completed by 326 smokers, were constructed on the basis of theory, empirical evidence, and expert review. RESULTS: The final Smoking Abstinence Expectancies Questionnaire (SAEQ) has 28 items and 4 internally consistent subscales: Negative Mood (e.g., "I would feel grouchy"), Somatic Symptoms (e.g., "My throat would feel dry"), Harmful Consequences (e.g., "I would feel like I'm dying"), and Positive Consequences (e.g., "I would feel calm"). The full scale showed good internal consistency (? = .86), test-retest reliability over a 2-week span (r = .82), as well as convergent and discriminant validity. CONCLUSIONS: The present study provides preliminary support for the SAEQ as a tool in smoking cessation research and treatment planning.

Development and validation of the French ASQoL questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVES: Ankylosing spondylitis (AS) is a chronic condition with significant impact on quality of life. The objective was to cross-culturally adapt into French and validate the ASQoL, an 18-item disease-specific self-report questionnaire. METHODS: Cross-cultural adaptation according to published guidelines used forward and backward translations, with an emphasis on expert committee informed decision making. A sample of active AS French patients answered the questionnaire twice, two weeks apart. A transition question helped identify those with no or some change over time. RESULTS: Cross-cultural adaptation resulted in rewording outcome categories from yes/no into true/false to better suit the French context. In 139 patients (mean age 40.9 years, 54.6% males) with active disease (mean BASDAI 4.8), the mean ASQoL score was 10.0. A 2-parameter Rasch model confirmed unidimensionality (chi-square fit p=0.86) with good item discrimination. Internal consistency was high (Cronbach's alpha 0.9). Convergent validity was ascertained by high correlation of ASQoL score with disease activity measures (r=0.57 to 0.79). Test-retest reproducibility was satisfactory (ICC 0.89). Responsiveness was moderate (SRM 0.44) in patients improving and good (SRM 0.68) in patients worsening over the period. CONCLUSIONS: These results show equivalence in content and validity of the cross-culturally adapted ASQoL for French speaking settings.

Dysphagia in Duchenne muscular dystrophy assessed by validated questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: Duchenne muscular dystrophy (DMD) leads to progressive muscular weakness and death, most typically from respiratory complications. Dysphagia is common in DMD; however, the most appropriate swallowing assessments have not been universally agreed and the symptoms of dysphagia remain under-reported. AIMS: To investigate symptoms of dysphagia in DMD and to determine the potential of the validated Sydney Swallow Questionnaire (SSQ) to diagnose dysphagia in this patient group. METHODS & PROCEDURES: Three participant groups completed the SSQ and the results were compared: nine DMD participants with dysphagia, six DMD participants without dysphagia and 12 healthy controls. OUTCOMES & RESULTS: The questionnaire scores for dysphagic DMD participants were significantly higher than for non-dysphagic DMD participants (p = 0.039) and for healthy controls (p ? 0.001). The diagnostic ability of the questionnaire was good for detecting dysphagia in participants with DMD (receiver operating characteristic (ROC) area under the curve = 0.89, p = 0.013), with a cut-off score of 224.5 (13.2%) giving a sensitivity of 0.78 and a specificity of 0.83 for determining dysphagia. Dysphagic participants rated time to eat a meal, swallowing hard food, swallowing thick liquids and needing to cough up or spit during meals with the highest severity of all questionnaire items. Results of the questionnaire by item are presented to inform the clinician of the symptoms of dysphagia in DMD. CONCLUSIONS & IMPLICATIONS: DMD leads to pervasive symptoms of dysphagia. The simple SSQ is a clinically informative assessment tool for patients with DMD.

Validation and psychometric properties of the Asthma Control Questionnaire among children.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Asthma Control Questionnaire (ACQ) is a patient-centered tool for evaluating asthma control. It has been validated in adults, but not well-validated among children. OBJECTIVE: We evaluated the reliability, validity, and responsiveness to change of the ACQ for assessing asthma control in children ages 6 to 17 years. A threshold value for poor disease control and a minimally important difference were also determined. METHODS: Data from 305 asthmatic children enrolled in a clinical trial were examined. The ACQ was administered at 8 visits. We analyzed results for the combined age group and for the 6- to 11-year-old and 12- to 17-year-old age groups separately. RESULTS: Overall, the Cronbach ? value (internal consistency) for the ACQ was 0.74 at baseline, and the intraclass correlation coefficient (test-retest reliability) for repeated questionnaires among stable patients was 0.53. The Pearson correlations between the ACQ and other asthma questionnaires were moderate to strong (-0.64 to -0.73). Mean ACQ scores were higher (worse) in patients whose peak flow decreased, who used more rescue medications, or who sought medical care for asthma than in patients who were stable (P < .0001 for all measures). Changes in ACQ scores were significantly different among patients with deteriorating, improving, or stable asthma symptoms (P ? .01). The optimal threshold indicating poor asthma control was 1.25 or greater. The minimally important difference was established to be 0.40. Results for the separate age groups were similar. CONCLUSION: The ACQ is a moderately reliable, valid, and responsive tool with adequate psychometric properties for assessing recent asthma control among children.

Validation of the chronic liver disease questionnaire in Serbian patients  

Science.gov (United States)

AIM: To translate into Serbian and to investigate the validity of the cross-culturally adapted the chronic liver disease questionnaire (CLDQ). METHODS: The questionnaire was validated in 103 consecutive CLD patients treated between October 2009 and October 2010 at the Clinic for Gastroenterology, Clinical Centre of Serbia, Belgrade (Serbia). Exclusion criteria were: age 2) ??and liver transplantation. Evaluation of the CLDQ was done based on the following parameters: (1) acceptance is shown by the proportion of missing items; (2) internal reliabilities were assessed for multiple item scales by using Cronbach alpha coefficient; and (3) in order to assess whether the allocation of items in the domain corresponds to their distribution in the original questionnaire (construction validity), an exploratory factor analysis was conducted. Discriminatory validity was determined by comparing the corresponding CLDQ score/sub-score in patients with different severity of the diseases. RESULTS: The Serbian version of CLDQ questionnaire completed 98% patients. Proportion of missing items was 0.06%. The total time needed to fill the questionnaire was ranged from 8 to 15 min. Assistance in completing the questionnaire required 4.8% patients, while 2.9% needed help in reading, and 1.9% involved writing assistance. The mean age of the selected patients was 53.8 ± 12.9 years and 54.4% were men. Average CLDQ score was 4.62 ± 1.11. Cronbach’s alpha for the whole scale was 0.93. Reliability for all domains was above 0.70, except for the domain “Activity” (0.49). The exploratory factor analysis model revealed 6 factors with eigenvalue of greater than 1, explaining 69.7% of cumulative variance. The majority of the items (66%) in the Serbian version of the CLDQ presented the highest loading weight in the domain assigned by the CLDQ developers: “Fatigue” (5/5), “Emotional function” (6/8), “Worry” (5/5), “Abdominal symptoms” (0/3), “Activity” (0/3), “Systemic symptoms” (3/5). The scales “Fatigue” and “Worry” fully corresponded to the original. The factor analysis also revealed that the factors “Activity” and “Abdominal symptoms” could not be replicated, and two new domains “Sleep” and “Nutrition” were established. Analysis of the CLDQ score/sub-score distribution according to disease severity demonstrated that patients without cirrhosis had lower total CLDQ score (4.86 ± 1.05) than those with cirrhosis Child’s C (4.31 ± 0.97). Statistically significant difference was detected for the domains “Abdominal symptoms” [F (3) = 5.818, P = 0.001] and “Fatigue” [F (3) = 3.39, P = 0.021]. Post hoc analysis revealed that patients with liver cirrhosis Child’s C had significantly lower sub-score “Abdominal symptoms” than patients without cirrhosis or liver cirrhosis Child’s A or B. For domain “Fatigue”, patients with cirrhosis Child’s C had significantly lower score, than non-cirrhotic patients. CONCLUSION: The Serbian version of CLDQ is well accepted and represents a valid and reliable instrument in Serbian sample of CLD patients.

Development of a questionnaire to assess medical competencies: Reliability and validity of the Questionnaire.  

UK PubMed Central (United Kingdom)

Introduction: While preparing a graduate survey for medical education in 2008 we realized that no instrument existed that would be suitable to evaluate whether the learning outcomes outlined in the Medical Licensure Act (ÄAppO) would be met. Therefore we developed the Freiburg Questionnaire to Assess Competencies in Medicine (Freiburger Fragebogen zur Erfassung von Kompetenzen in der Medizin, FKM)(1) which has been revised and extended several times since then.Currently the FKM includes 45 items which are assigned to nine domains that correspond to the CanMEDS roles: medical expertise, communication, team-work, health and prevention, management, professionalism, learning, scholarship, and personal competencies.Methods: In order to test the reliability and validity of the questionnaire we have repeatedly surveyed medical students and residents since May 2008. In this article we report on the results of a cross-sectional study with 698 medical students from the preclinical and clinical years. In addition, we report the results of a survey of 514 residents who were up to two years into their residency.Results and conclusions: In summary, results show that the scales of the FKM are reliable (Cronbach's ? between .68 and .97). Significant differences in means between selected groups of students support the measure's construct validity. Furthermore, there is evidence that the FKM might be used as a screening tool e.g. in graduate surveys to identify weaknesses in the medical education curriculum.

Reliability and validity of the Paediatric Volitional Questionnaire - Chinese version.  

UK PubMed Central (United Kingdom)

OBJECTIVE: The purpose of this study is to examine the psychometric properties of the Chinese version of the Paediatric Volitional Questionnaire (PVQ-C) for use amongst preschoolers in Taiwan. METHODS: Forty preschoolers with developmental delays were randomly selected from northern Taiwan, along with another 40 typically developing preschoolers. The data was analysed using Rasch measurement model for construct validity and classical test theory for item reliability, intra- and inter-rater reliability, and convergent validity. RESULTS: The results indicated the PVQ items of PVQ-C fit into a unidimensional continuum of volition (logit -6.63~3.05) with 2 items representing differential item functioning for diagnostic group. The person-fit statistics showed that 83% participants' response could be appropriately estimated and stratified (separation index?=?1.86). Using a modified 3-point rating scale resulted in acceptable item reliability (0.97), intra-rater reliability (0.412-1.0), 86% PVQ items in test-retest reliability >?0.4, and convergent validity (r?=?0.562-0.656). CONCLUSIONS: The PVQ-C is regarded as a reliable and valid instrument for assessing the volitional status of children, as a reference for subsequent clinical judgement, and for client-centred intervention programmes and treatment effects.

Reliability and validity study of parental feeding style questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Aim: We aimed to confirm the validity and internal reliability of Parental Feeding Style Questionnaire (PFSQ) which was a parent-report measure and was designed to assess variations in parent’s feeding styles.Material and Method: For this cross sectional study, PFSQ was translated to Turkish and conducted among parents of both preschool students and patients who applied to the pediatric outpatient clinic. 468 of 650 responded questionnaires were examined for factor structure. The data were analyzed by PASW ver.18 and SPSS program.Results: The questionnaire was conducted among parents of 243 boys and 225 girls, the mean age was 5.84±1.28 Reliability coefficients (Cronbach Alphas) of subscales ranged from 0.54 to 0.83 Factor structure, internal reliability and subscale correlations were similar to original PFSQ.Conclusions: Evidence for associations between parental feeding style and subsequent weight trajectory of children needs to be established through longitudinal follow-up studies.Given the dramatic increase in obesity that has been observed in recent years, and particularly the increase in childhood obesity, investment in research in the development of obesity in childhood should be given a high priority.

[Validation of the Japanese version of the Parkinson's Disease Questionnaire].  

UK PubMed Central (United Kingdom)

UNLABELLED: The PDQ-39 (Parkinson's Disease Questionnaire-39) is a specific quality-of-life (QOL) scale for patients with Parkinson's disease (PD). It evaluates the dysfunction of daily living and quality of life. We developed the Japanese-translated version of PDQ-39 and examined the validity of the PDQ-39 in Japanese PD patients. SUBJECTS: A total of 156 patients with PD were studied (age 35-86 years, Hoehn-Yahr stage 1 to 4). None of the patients had dementia. METHODS: Semi-structured interviews were conducted by one trained interviewer. The PDQ-39, SF-36 (36-item short form of the Medical Outcome Study questionnaire), EQ5D (Euro Qol), and NAS-J (Nottingham Adjustment Scale Japanese version) were used for evaluation. The attending physician of each patient rated the patient's condition by using the UPDRS (Unified Parkinson's Disease Rating Scale). RESULTS: Exploratory factor analysis, Cronbach alpha, and construct validity were fair, and there were significant correlations between the results of the PDQ-39 and the corresponding parts of the UPDRS and SF-36, and the Hoehn-Yahr stage, respectively. CONCLUSION: The Japanese version of the PDQ-39 is valuable for evaluating the QOL of Japanese patients with PD. Results of comparison of PDQ-39 with other scales of the QOL such as NAS-J suggest the possibility that acceptance of the disease and feelings of self-achievement improve the QOL of patients with Parkinson's disease.

Validation of Assessment for Learning Questionnaires for teachers and students.  

UK PubMed Central (United Kingdom)

BACKGROUND: Assessment can be a powerful force in promoting student learning. Still, few measures exist to gauge Assessment for Learning (AFL) in the classroom. Literature on AFL suggests that it encompasses both a monitor to track student progress as well as a scaffold to show or help students recognize in what areas they need to improve. AIMS: Based on a review of recent attempts to measure the AFL, we constructed Assessment for Learning Questionnaires for Teachers (TAFL-Q) and for students (SAFL-Q) for evaluating perceptions regarding AFL practices in classrooms using matching items. SAMPLE: The total sample included 1,422 students (49% girls, 51% boys) and 237 teachers (43% females, 57% males) in lower vocational secondary education. METHODS: The 28-item questionnaires were examined by means of confirmatory factor analysis (CFA) using EQS on one random half of the sample. The CFA was cross-validated on the second half. Measurement invariance tests were conducted to compare the students and teacher versions of the questionnaires. RESULTS: CFA revealed a stable second-order two-factor structure that was cross-validated: perceived monitoring, and perceived scaffolding subsumed under a common factor: AFL. Tests for measurement invariance showed that the parallel constructs were measured similarly for both students and teachers. CONCLUSION: The TAFL-Q and SAFL-Q capture the construct AFL in two subscales: Monitoring and Scaffolding, and allows for comparisons between teacher and student perceptions. The instruments can be useful tools for teachers and students alike to identify and scrutinize assessment practices in classroom.

Validity of the international physical activity questionnaire in the arctic.  

UK PubMed Central (United Kingdom)

PURPOSE: Information about physical activity (PA) in Greenland is limited, partly because of a lack of validated instruments in countries with non-Western living conditions. We modified the long form of the International Physical Activity Questionnaire (IPAQ-L) to arctic living conditions. The aim of the study was to compare IPAQ-L estimates with combined accelerometry and heart rate monitoring (ACC + HR) in a population-based study of adult Inuit in Greenland. METHODS: Cross-sectional data were collected by face-to-face interview and ACC + HR monitoring among Inuit (18 yr and above) in Greenland during 2005-2010 (n = 1508). PA energy expenditure (PAEE) and time spent sedentary and on PA at moderate and vigorous intensity were derived from IPAQ-L and ACC + HR. Estimates were compared using Bland-Altman agreement analysis and Spearman correlations stratified by sex, place of residence (capital, towns, and villages), and age groups. RESULTS: Questionnaire-based PAEE was moderately correlated with objectively measured PAEE (r = 0.20-0.35, P < 0.01). Self-reported time spent at moderate- and vigorous-intensity PA and time spent sedentary were weakly correlated with the objective measure (r = 0.11-0.31). Agreement analyses showed relatively small median differences for all measures of PA; however, time spent at moderate-intensity PA was substantially overreported by IPAQ-L when including walking (>1.5 h·d, P < 0.001) but not when excluding walking. CONCLUSIONS: The IPAQ-L adapted to arctic living conditions in Greenland had a moderate level of agreement with combined accelerometry and heart rate monitoring for total PAEE at population level, but it was less valid to measure different intensities of PA and sedentary activity. Validity did not differ markedly between rural and urban communities.

Reliability and Internal Validity of the Michigan Hand Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Michigan Hand Outcomes Questionnaire (MHQ) remains one of very few to be based on validated and systematic methods in its creation. However, test-retest reliability and internal validity have not been appropriately investigated in any other English-speaking population outside the original development sample. The objective of this study is to examine the reliability and internal validity of the MHQ in a Canadian population. METHODS: All patients with a clinical hand problem but no hand immobilization who attended our Plastic Surgery Clinic were invited to participate in this study. Patients were asked to complete the MHQ, and then contacted to arrange for completion of the MHQ a second time. Internal validity was estimated using Cronbach alpha. Reliability was estimated using the method of Bland and Altman, and intraclass correlation coefficients. Correlation analysis between score differences and time between tests was performed. RESULTS: Full versions of the MHQ were completed by 116 participants on their initial visit, while only 77 participants completed a second MHQ. Cronbach alpha ranged from 0.84 to 0.95 for the MHQ subscales. Intraclass-correlation coefficients ranged from 0.71 to 0.84 for the subscales. The magnitude of the limits of agreement for the subscales ranged from 13.8 to 26.2. The difference in scores between the first and second tests was not related to the time between tests. CONCLUSION: The high values of Cronbach alpha indicate high internal validity, but that there may be redundancy between items in the MHQ, which could be eliminated without losing information. Reliability of the MHQ is considered moderate. The limits of agreement are considered wide, indicating potential issues with respect to interpretation of a change in score between 2 administrations of the MHQ.

Development and validation of the Infant Feeding Style Questionnaire.  

UK PubMed Central (United Kingdom)

This study describes and validates the Infant Feeding Style Questionnaire (IFSQ), a self-report instrument designed to measure feeding beliefs and behaviors among mothers of infants and young children. Categorical confirmatory factor analysis was used to estimate latent factors for five feeding styles, laissez-faire, restrictive, pressuring, responsive and indulgent, and to validate that items hypothesized a priori as measures of each style yielded well-fitting models. Models were tested and iteratively modified to determine the best fitting model for each of 13 feeding style sub-constructs, using a sample of 154 low-income African-American mothers of infants aged 3-20 months in North Carolina. With minor changes, models were confirmed in an independent sample of 150 African-American first-time mothers, yielding a final instrument with 39 questions on maternal beliefs, 24 questions on behaviors and an additional 20 behavioral items pertaining to solid feeding for infants over 6 months of age. Internal reliability measures for the sub-constructs ranged from 0.75 to 0.95. Several sub-constructs, responsive to satiety cues, pressuring with cereal, indulgent pampering and indulgent soothing, were inversely related to infant weight-for-length z-score, providing initial support for the validity of this instrument for assessing maternal feeding beliefs and behaviors that may influence infant weight outcomes.

Validation of Italian multiple sclerosis quality of life 54 questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVES: Health related quality of life (HRQOL) inventories are multi-dimensional measures of patient-centred health status developed for clinical research. The MS quality of life 54 (MSQOL-54) is an MS-specific HRQOL inventory originally devised for English speaking patients. It consists of a core measure, the 36-item short form health survey (SF-36) previously adapted into Italian, and 18 additional items exploring domains relevant to patients with MS (MS-18 module). The authors translated and culturally adapted into Italian the MS-18 module of the MSQOL-54 questionnaire, and clinically validated the whole questionnaire. METHODS: The MS-18 module was translated following the methodology of the International Quality of Life Assessment (IQOLA) project. The MSQOL-54 was validated in 204 consecutive patients with MS seen between April and September 1997 at three participating centres. The questionnaire was explained by the physician who also administered the expanded disability status scale (EDSS) and mini mental status scale examination, and the patient filled in the MSQOL-54 and Beck depression inventory questionnaires (BDI), with assistance if required. The contribution of impairments and disabilities to MSQOL-54 scores were assessed, and mean scores were compared with normative data for the general Italian population, and with the original sample of United States MS patients. RESULTS: The mean age of the 204 patients was 42 years; mean EDSS score was 4.5 (range 0-8. 5). Patients' participation in the assessment was satisfactory, and all scales satisfied the usual psychometric standards. The characteristics of the United States sample matched those of our patients in all but gender (72% United States patients v 52% Italian patients were women), and education (90% United States patients and 44% Italian patients completed high school); MSQOL-54 profiles were also similar. The EDSS was significantly associated with the physical health composite but not with the mental health composite score. Multiple linear regression modelling showed that age and BDI independently predicted physical health composite (p < 0.001), and mental health composite (p < 0.001). Clinical worsening in the previous year had an independent effect on the physical health composite (p < 0.001). CONCLUSIONS: The Italian version of MSQOL-54 is easy to administer and is well accepted by patients. Neurological impairment has a limited influence on perceived quality of life, while age and depressive symptoms has a major influence.

Validation of the Spanish version of the Asthma Control Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Asthma Control Questionnaire (ACQ) has not been validated in the Spanish population, and the fact that it requires spirometry poses an important limitation on its widespread use in the primary care setting in Spain. OBJECTIVE: The aim of this study was to evaluate the psychometric properties of the Spanish version of the ACQ. METHODS: In this multicenter, prospective study, consecutive adult patients with persistent asthma were recruited at 62 respiratory and allergy units across Spain. Patients were assessed at baseline and at weeks 2 and 6. The following clinical variables were recorded: lung function (forced expiratory volume in 1 second [FEV(1)]), symptoms, exacerbations, concomitant diseases, asthma severity according to the Global Initiative for Asthma international guideline, and asthma control as perceived by patients and physicians through direct ad hoc questions. The latter measures were derived specifically for this study. Patients self-completed the ACQ at all visits before the rest of the study variables were recorded. The ACQ's feasibility, validity, reliability, and sensitivity to change were assessed. Cross-sectional and longitudinal validity was assessed using the relationship between ACQ score and clinical parameters. Sensitivity to change was assessed by estimating the global effect size and the minimal important difference (MID). Reliability was assessed using estimation of the Cronbach alpha coefficient (CCalpha) and intraclass correlation coefficient (ICC). RESULTS: A total of 607 patients were included. The mean (SD) age was 45.6 (17.1) years and 61.4% of the patients were women. Of these 607, 235 (39%) had mild asthma; 246 (41%), moderate; and 126 (21%), severe. Mean (SD) time to complete the ACQ was 3.9 (4.4) minutes. The Pearson correlation coefficient in the relationship between ACQ and FEV(1) (% predicted value) was -0.23. ACQ was found to be significantly related to asthma severity and intensity and frequency of symptoms (coughing, wheezing, and dyspnea) (both, P < 0.001). Change in ACQ was significantly related to changes in FEV(1), intensity and frequency of symptoms, and number of exacerbations (all, P < 0.001). The global effect size of ACQ was 0.46 and the MID was 0.47 point of a maximum of 6. CCalpha was 0.90 and ICC was 0.86. CONCLUSION: In these adults with asthma in Spain, the Spanish version of the ACQ was found to be a reliable and valid questionnaire, suggesting that it can be used in this population as a discriminative and evaluative instrument.

[Validation of the Argentine version of the Mood Disorder Questionnaire].  

Science.gov (United States)

Bipolar Disorder (BD) is a severe and recurrent medical illness with relevant impact on quality of life and functioning for patients. However, we still have significant deficits on its detection. One of the ways to improve the accurate recognition of the disease consists on the administration of screening tools such as the Mood Disorder Questionnaire (MDQ). The main aim of this investigation was to validate the Argentine version of the MDQ and determine the optimal cut off for outpatients who suffer from mood disorders in our country. The total sample consisted of 354 adult outpatients with diagnosis of BD type I, II and NOS, and Unipolar - Major Mood Disorders (MDD), enrolled between 2007 and 2008, from 11 sites of Argentina. The MDQ positively detected 53.6% of BD patients and 96.6% of MDD patients. The best cut off for our sample was established in 5 points for item 1 of the MDQ. By deleting the item 3 of the questionnaire, the performance was significantly improved. In conclusion, the Argentine version of the MDQ has demonstrated the same ability for detecting patients with BD of the English original version on a psychiatric population. PMID:22091450

The Patient Experiences Questionnaire: development, validity and reliability.  

UK PubMed Central (United Kingdom)

OBJECTIVE: . To describe the development of the Patient Experiences Questionnaire (PEQ) and to evaluate reliability and validity of constructed summed rating scales. DESIGN: Literature review, focus groups and pilot surveys. Two national cross-sectional studies performed in 1996 and 1998. SETTING: Two postal surveys in a national sample of 14 hospitals stratified by geographical region and hospital size. Subjects. Patients consecutively discharged from surgical wards and wards of internal medicine. The surveys included 36 845 patients and 19 578 responded (53%). RESULTS: We constructed 10 summed rating scales based on factor analysis and theoretical considerations: Information on future complaints, Nursing services, Communication, Information examinations, Contact with next-of-kin, Doctor services, Hospital and equipment, Information medication, Organization and General satisfaction. Eight scales had a Cronbach alpha coefficient of >0.70, the remaining two were >0.60. Repeatability was >0.70 for five scales and >0.60 for the remaining scales. CONCLUSIONS: The PEQ is a self-report instrument covering the most important subjects of interest to hospital patients. Results are presented as 10 scales with good validity and reliability. It emphasizes practicability and comprehensibility while at the same time providing sufficient information about domains applicable to most patients admitted to medical and surgical wards.

Validation of the Netherlands physical activity questionnaire in Brazilian children  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Physical activity instruments can be subjective or objective. There is a need to assess the reliability of these instruments, especially for researches in children. The aim of this study was to determine the validity of the Netherlands Physical Activity Questionnaire (NPAQ). Methods Population under study were Brazilian children aged 4 to 11 years old, enrolled in a population-based study. Data collection took place in two distinct moments: 1) application of the NPAQ by face-to-face interviews with mothers' children and 2) utilization of accelerometers by children as the reference method. GT1M Actigraph accelerometer was worn for five consecutive days. Validity analyses were performed by sensitivity and specificity and ROC (Receiver Operator Characteristic) curve. Results Two hundred and thirty nine children participated in both phases of the study. A total of 73.2% children achieved the recommendation of 60 min/day of moderate to vigorous physical activity. The mean and median of the NPAQ score were 25.5 and 26, respectively. The score ranged from 7 to 35 points. The correlation coefficient between the NPAQ and the time spent in moderate to vigorous physical activities was 0.27. Based on the area under the ROC curve, the median value presented the best indicators of sensitivity (59.4%) and specificity (60.9%), and the area under curve was 0.63. The predictive capacity of the NPAQ to identify active children was high regardless the cut-off point chosen. This capacity was even higher if the score was higher than 30. Conclusions Based on sensitivity and specificity values, the NPAQ did not show satisfactory validity. The comparison of the reliability of the NPAQ with other instruments is limited, but correlation coefficients found in this study are similar to others. Physical activity level of children estimated from the NPAQ must be interpreted cautiously, and objective measures such as accelerometers should be encouraged.

The water balance questionnaire: design, reliability and validity of a questionnaire to evaluate water balance in the general population.  

UK PubMed Central (United Kingdom)

There is a need to develop a questionnaire as a research tool for the evaluation of water balance in the general population. The water balance questionnaire (WBQ) was designed to evaluate water intake from fluid and solid foods and drinking water, and water loss from urine, faeces and sweat at sedentary conditions and physical activity. For validation purposes, the WBQ was administrated in 40 apparently healthy participants aged 22-57 years (37.5% males). Hydration indices in urine (24 h volume, osmolality, specific gravity, pH, colour) were measured through established procedures. Furthermore, the questionnaire was administered twice to 175 subjects to evaluate its reliability. Kendall's ?-b and the Bland and Altman method were used to assess the questionnaire's validity and reliability. The proposed WBQ to assess water balance in healthy individuals was found to be valid and reliable, and it could thus be a useful tool in future projects that aim to evaluate water balance.

Validity and reproducibility of the NORBAGREEN food frequency questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To measure the validity and reproducibility of the NORBAGREEN food frequency questionnaire (FFQ). SUBJECTS/METHODS: In Finland, 125 subjects aged 25-64 years sampled from the five main regions of the FINDIET 2002 Study and in Lithuania, 99 citizens of Kaunas aged 19-75 years participated in the study. Reference methods for the FFQ were two 3-day FFQs in Finland and four 24-h recalls in Lithuania. The FFQ was repeated after 6-8 months in both countries. The outcome of the FFQ1 was correlated with the outcome of the reference methods and with the outcome of repeated FFQ2. Cross-classification of food intakes by FFQ1 and the reference methods was examined in tertiles. RESULTS: Validity correlations (FFQ vs the reference method, Spearman's correlation) were for vegetables, fruit and bread 0.50 (P<0.01), 0.53 (P<0.01) and 0.54 (P<0.01) in Finland; and 0.55 (P<0.01), 0.31 (P<0.01) and 0.51 (P<0.01) in Lithuania, respectively. Correlations were smaller for potatoes and fish. The overall proportion categorized in the same or adjacent intake tertiles with the two instruments was over 83% in both countries. Reproducibility correlations varied between 0.51 and 0.75 in the Finnish study, and between 0.51 and 0.83 in the Lithuanian study. CONCLUSIONS: The NORBAGREEN FFQ can be used to rank subjects according to vegetable, fruit and bread consumption. Questions on fish and potato consumption need to be developed further.

Validation of the Drinking Motives Questionnaire (DMQ) in older adults.  

UK PubMed Central (United Kingdom)

Drinking motives have been established as an important construct in the prediction of alcohol use and drinking problems among younger adults, but there is little understanding about the drinking motivations of older adults. Although emerging evidence shows the importance of studying older adults' own reasoning for their alcohol consumption, measures that have been used to assess such reasons lack psychometric assessment. This study aims to validate the three-dimensional structure of the Drinking Motives Questionnaire (DMQ) in older adults and to investigate the relationships between drinking motives and alcohol use. A sample of community dwelling older adults (N=370) completed self-report measures assessing drinking behavior and motives for drinking. Using confirmatory factor analysis, the results supported a three-factor model of drinking motives. Multi-group analysis of invariance showed support for configural and metric invariance, and partial support was met for scalar invariance. Social motivations for drinking were the most frequently endorsed, followed by enhancement, and coping motives. Males reported more frequent drinking for each of the three motives. Social motives were consistently related to drinking behaviors and coping had a direct relationship to drinking problems. Overall, the study shows that the DMQ has promise as a measure for use with older adults.

Acceptance of tinnitus: validation of the tinnitus acceptance questionnaire.  

UK PubMed Central (United Kingdom)

The concept of acceptance has recently received growing attention within tinnitus research due to the fact that tinnitus acceptance is one of the major targets of psychotherapeutic treatments. Accordingly, acceptance-based treatments will most likely be increasingly offered to tinnitus patients and assessments of acceptance-related behaviours will thus be needed. The current study investigated the factorial structure of the Tinnitus Acceptance Questionnaire (TAQ) and the role of tinnitus acceptance as mediating link between sound perception (i.e. subjective loudness of tinnitus) and tinnitus distress. In total, 424 patients with chronic tinnitus completed the TAQ and validated measures of tinnitus distress, anxiety, and depression online. Confirmatory factor analysis provided support to a good fit of the data to the hypothesised bifactor model (root-mean-square-error of approximation = .065; Comparative Fit Index = .974; Tucker-Lewis Index = .958; standardised root mean square residual = .032). In addition, mediation analysis, using a non-parametric joint coefficient approach, revealed that tinnitus-specific acceptance partially mediated the relation between subjective tinnitus loudness and tinnitus distress (path ab = 5.96; 95% CI: 4.49, 7.69). In a multiple mediator model, tinnitus acceptance had a significantly stronger indirect effect than anxiety. The results confirm the factorial structure of the TAQ and suggest the importance of a general acceptance factor that contributes important unique variance beyond that of the first-order factors activity engagement and tinnitus suppression. Tinnitus acceptance as measured with the TAQ is proposed to be a key construct in tinnitus research and should be further implemented into treatment concepts to reduce tinnitus distress.

Spinal appearance questionnaire: factor analysis, scoring, reliability, and validity testing.  

UK PubMed Central (United Kingdom)

STUDY DESIGN: Cross sectional. OBJECTIVE: This study presents the factor analysis of the Spinal Appearance Questionnaire (SAQ) and its psychometric properties. SUMMARY OF BACKGROUND DATA: Although the SAQ has been administered to a large sample of patients with adolescent idiopathic scoliosis (AIS) treated surgically, its psychometric properties have not been fully evaluated. This study presents the factor analysis and scoring of the SAQ and evaluates its psychometric properties. METHODS: The SAQ and the Scoliosis Research Society-22 (SRS-22) were administered to AIS patients who were being observed, braced or scheduled for surgery. Standard demographic data and radiographic measures including Lenke type and curve magnitude were also collected. RESULTS: Of the 1802 patients, 83% were female; with a mean age of 14.8 years and mean initial Cobb angle of 55.8° (range, 0°-123°). From the 32 items of the SAQ, 15 loaded on two factors with consistent and significant correlations across all Lenke types. There is an Appearance (items 1-10) and an Expectations factor (items 12-15). Responses are summed giving a range of 5 to 50 for the Appearance domain and 5 to 20 for the Expectations domain. The Cronbach's ? was 0.88 for both domains and Total score with a test-retest reliability of 0.81 for Appearance and 0.91 for Expectations. Correlations with major curve magnitude were higher for the SAQ Appearance and SAQ Total scores compared to correlations between the SRS Appearance and SRS Total scores. The SAQ and SRS-22 Scores were statistically significantly different in patients who were scheduled for surgery compared to those who were observed or braced. CONCLUSION: The SAQ is a valid measure of self-image in patients with AIS with greater correlation to curve magnitude than SRS Appearance and Total score. It also discriminates between patients who require surgery from those who do not.

Word reading threshold and mild cognitive impairment: a validation study  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background It was previously found, in a pilot study, that Word Reading Threshold (WRT) test is abnormally prolonged in individuals with Alzheimer’s disease (AD) and Mild Cognitive Impairment (MCI), with high sensitivity and specificity. This validation study examines the WRT test as a prognostic tool in MCI individuals. We wish to confirm in a larger group the sensitivity and specificity of the WRT test and determine whether it is influenced by deterioration on other cognitive domains. Methods We measured WRT in 60 MCI individuals, 29 AD patients, and 33 normal elderly control (NE). We followed the MCI individuals over 8 years to monitor who progressed to dementia. Results We found a statistically significant difference in WRT scores between the three groups. However, using the same cutoff of 85 milliseconds suggested by Massoud and his colleagues, we found lower diagnostic sensitivity (72%) and specificity (76%) when comparing NC and AD. Furthermore, the test did not clearly differentiate MCI individuals who progressed to dementia from those who did not. WRT was found to correlate to some degree with other cognitive domains, especially attention. Conclusions We conclude that the WRT is insufficient alone as a diagnostic tool for prodromal AD.

Establishing the validity and reliability of a pediatric pain knowledge and attitudes questionnaire.  

Science.gov (United States)

Children continue to experience unrelieved pain during hospitalization, despite the evidence to guide nurses' pain management practices being readily available. Nurses' knowledge and attitudes have been identified as a possible reason for suboptimal pain management. This study examines the validity and reliability of an existing questionnaire to validate it for use in the population of interest. Initial testing demonstrated low reliability and validity. Modifications to the questionnaire were made on the basis of these results and the feedback provided by experts in pediatric pain management. Subsequent testing demonstrated good validity and reliability, suggesting that the questionnaire is appropriate for measuring nurses' knowledge and attitudes in relation to pediatric pain management.

Back pain management in primary care: development and validity of the Patients' and Doctors' Expectations Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: Back pain is a common disorder, with the doctor being the first point of contact for help. Biopsychosocial management of back pain has been shown to be problematic. Meeting patients' expectations is alleged to play a vital role in concordance, adherence and satisfaction. A more potent aspect, however, could be a state of matched patient- doctor expectations with regard to the consultation process and outcome, but this aspect has not been fully investigated and there is currently no valid and specific measure of this dimension. AIM: To report on the development of a newly designed patient and doctor expectations questionnaire that measures the matching of their expectations with regard to the back pain consultation in primary care, and to establish the validity and internal consistency of the new tool. METHODS: A literature review was carried out and a draft 36-item questionnaire was developed. Thirty-eight subjects (7 researchers, 20 patients and 11 doctors) tested the questionnaire. Each subject gave feedback on the questionnaire design and was also asked to fill in a previously validated tool, the Patients' Intentions Questionnaire (PIQ), to establish the concurrent validity of the newly designed expectations questionnaire. Construct validity was established by calculating the Spearman correlation coefficient, and Cronbach's alpha was computed to reflect the internal consistency of the instrument. FINDINGS: The results of the validity questionnaire showed that the questionnaire was perceived as simple, clear and easy to understand and appropriate to the intended aim. Spearman correlation coefficients between the Patients' Expectations Questionnaire and PIQ showed significant correlation ( r = 0.65), reflecting good concurrent validity, while Cronbach's alpha was 0.831, reflecting good internal consistency. CONCLUSION: The newly designed questionnaire showed good face, content and construct validity as well as good internal consistency, and thus can be used as a valid and reliable measure for back pain-specific expectations of the process and outcome of the consultation in primary care settings.

Toddler autism screening questionnaire: development and potential clinical validity.  

UK PubMed Central (United Kingdom)

No feasible screening instrument is available for early detection of children with autism in Taiwan. The existing instruments may not be appropriate for use in Taiwan due to different health care systems and child-rearing cultures. The purpose of this study was to develop and test a screening questionnaire for generic autism. The initial 18-item screening questionnaire was developed by a child psychiatrist using face-to-face interviews with 10 families of children with autism and then tested on a sample of families of 18 children with autism and of 59 typically developing children. Of these 18 items, 15 had fair or better item discrimination (kappa >0.20) and were selected for the revised screening questionnaire. In the revised questionnaire, cutoff scores of 5 and 6 offered 100% sensitivity and 96.5% specificity, with the area under the receiver operating characteristic curve of 0.983. The revised screening instrument has high sensitivity and specificity, making it potentially useful for screening Taiwanese children at risk for autism. This instrument should be further tested in a population-based study.

Development and validation of a lifetime exposure questionnaire for use among Chinese populations.  

UK PubMed Central (United Kingdom)

The sunlight exposure questionnaire for use in the Chinese population was constructed based on extensive literature review and item suitability for measuring life-time exposure. The content validity index (CVI) was derived from ratings by, an expert panel to assess the item content and relevance. 650 population-based Chinese women completed the sunlight exposure questionnaire through telephone interview. To assess the questionnaire reliability, 94 women were re-interviewed after 2 weeks. 98.4% of the sunlight exposure questionnaire items were found to have valid CVI (>0.83). The Scree plot and the Principal Components Factor Analysis showed a two-factor construct was appropriate and no questionnaire item needed to be excluded. The questionnaire also had a good test-retest reliability (ICC: 0.59-0.93; k: 0.51-100). This sunlight exposure questionnaire was found to be adequate for measurement of life-time sunlight exposure among Hong Kong Chinese women.

Young Schema Questionnaire-Short Form: Colombian validation [Young Schema Questionnaire – Short Form, Validación en Colombia  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this study was to assess the factor structure of the Young Schema Questionnaire-Short Form ([YSQ-SF], Young, 1999) and the gender differences in early maladaptive schemas. The study took place in Colombia, where 1392 university students (541 male y 851 female) completed the YSQ-SF. The results confirmed the existence of the original 15 first-order factors, in consistency with the 15 theoretical schemas. However, the results for the second-order structure were less conclusive, as both a three second order factor and a five second order factor structures showed similar fit indices. Alpha coefficients for the schemas rated between 0.74 and 0.89. Men scored higher than women on several schemas.

[Cross-cultural adaptation and health questionnaires validation: revision and methodological recommendations].  

UK PubMed Central (United Kingdom)

The simple translation of a questionnaire may lead to misinterpretation due to language and cultural differences. When using questionnaires developed in other countries and languages in scientific studies it is necessary, besides the translation, to carry out a cross-cultural adaptation and validation. Our objective was to review the literature on cross-cultural adaptation and validation (CCAV) of health questionnaires, and to synthesize and propose recommendations based on the scientific literature to facilitate this process. The CCAV should follow a systematic process. Two steps are recommended: 1) cross-cultural adaptation: direct translation, synthesis, back translation, expert committee consolidation and pre-testing, and 2) validation (with up to seven steps): assessment of internal consistency, reliability, intra- and inter-observer reliability, face, content, criterion and construct validity. Lack of equivalence between questionnaires limits the comparability of results among populations with different cultures and languages and the exchange of information in the scientific community.

The development and validation of a low back pain knowledge questionnaire - LKQ  

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVE: The objective of this study was to develop and validate a questionnaire on specific knowledge about low back pain entitled "The Low Back Pain Knowledge Questionnaire". INTRODUCTION: There is a need for instruments to assess patient knowledge regarding chronic illness. Such methods can contribute to the education of patients. METHODS: The Low Back Pain Knowledge Questionnaire was developed through five focus groups. The questionnaire was distributed to 50 patients to assess their comprehension of the terms. To assess the reproducibility, 20 patients were surveyed by two different interviewers on the same day and twice by a single interviewer with a one-to-two week interval. For the construct validation, the Low Back Pain Knowledge Questionnaire was given to 20 healthcare professionals with knowledge on low back pain and 20 patients to determine whether the questionnaire would discriminate between the two different populations. To assess the sensitivity of the questionnaire to changes in the knowledge level of the patients, it was given to 60 patients who were randomly assigned to the Intervention Group and the Control Group. The Intervention Group answered the questionnaire both before and after attending a chronic back pain educational program (back school), whereas the Control Group answered the questionnaire twice with an interval of one month and no educational intervention. RESULTS: The focus groups generated a questionnaire with 16 items. The Spearman's correlation coefficient and the intra-class correlation coefficients ranged from 0.61 to 0.95 in the assessments of the intra-observer and inter-observer reproducibility (p< 0.01). In the construct validation, the healthcare professionals and patients showed statistically different scores (p< 0.001). In the phase regarding the sensitivity to change, the Intervention Group exhibited a significant increase in their specific knowledge over the Control Group (p< 0.001). CONCLUSION: The Low Back Pain Knowledge Questionnaire was validated and proved to be reproducible, valid and sensitive to changes in patient knowledge.

Validation of a Spanish translation of the Gamblers' Beliefs Questionnaire.  

UK PubMed Central (United Kingdom)

The U.S. Spanish-speaking population has rapidly increased in recent decades and there is a need for psychometrically supported assessment measures for researchers and clinicians who work with this population. A Spanish version of a self-report measure of gamblers' cognitive distortions [Gamblers' Beliefs Questionnaire (GBQ); Steenbergh, Meyers, Whelan, & May, 2002] was translated and psychometrically evaluated in a sample of 219 Spanish-speaking Hispanics residing in the southeast United States. The GBQ-S showed high internal consistency (? = .95). Factor analytic data supported a factor structure similar to the initial psychometric evaluation of the English version. Probable pathological gamblers reported significantly more cognitive distortions on the GBQ-S than nongamblers and nonpathological gamblers.

This study addressed the need for a multidimensional scale, the Role Conflict Questionnaire (RCQ) to address some of the limitations of a unitary measure. Opsomming Ten spyte van die feit dat rolkonflik oorspronklik as n multidimensionele konstruk ontwikkel is sowel as verskeie aanbevelings dat die meting van verskillende dimensies meer bruikbaar is in beide navorsings- en diagnostiese verband, word dit steeds tipies eendimensioneel gemeet.

[Cross-cultural adaptation and validation of Lithuanian questionnaires for the spondyloarthropathies].  

UK PubMed Central (United Kingdom)

UNLABELLED: Original English questionnaires--Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Patient Global Score, and Bath Ankylosing Spondylitis Disease Activity Index--are designed to evaluate health, physical and psychical state of patients with spondyloarthropathies and to assess efficiency of the treatment. OBJECTIVE: The objective of the study was to adapt Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Patient Global Score, Bath Ankylosing Spondylitis Disease Activity Index questionnaires to the Lithuanian context and examine their psychometric aspects: reliability and validity. PATIENTS AND METHODS: Validation and linguistic and cultural adaptation of Lithuanian questionnaires were performed according to the requirements for adaptation of the international questionnaires. Psychometric features of Lithuanian questionnaires were examined in 139 patients with spondyloarthropathies. The validity of questionnaires was tested by comparing these questionnaires with Health Assessment Questionnaire Modified for Spondyloarthropathies, metrology indices (tragus-to-wall distance, lateral flexion, modified Schober's distance, intermalleolar distance), pain intensity, patient's well-being, physician's assessment of the disease activity, and total enthesis count. The reliability of questionnaires was assessed by determining internal consistency of scales and scale stability and by calculating the intraclass correlation coefficient. RESULTS: The linguistic and cultural adaptation of these questionnaires was made during the study. Internal consistency was high for functional and disease activity index (Cronbach alpha>/=0.80) and moderate for the Bath Ankylosing Spondylitis Patient Global Score (Cronbach alpha=0.58). High stability in regard to time was characteristic of all three questionnaires (intraclass correlation coefficient >0.95). A significant association between the separate questions of examined instruments, their joint results and other factors reflecting patient's health was established. CONCLUSIONS: Bath Ankylosing Spondylitis Functional Index, Bath Ankylosing Spondylitis Patient Global Score, and Bath Ankylosing Spondylitis Disease Activity Index questionnaires in Lithuanian fully correspond to psychometric requirements. They are appropriate and relevant in assessing the influence of spondyloarthropathies on a patient's health.

Relative validity of a food frequency questionnaire to assess nutrient intake in pregnant women.  

UK PubMed Central (United Kingdom)

BACKGROUND: To date, there are no food frequency questionnaires that have been validated to assess nutrient intakes in pregnant women in Ireland. The present study aimed to assess the relative validity of a self-administered food frequency questionnaire during pregnancy. METHODS: The food frequency questionnaire was administered once during pregnancy between 12 and 34 weeks. Participants also completed a 3-day food diary during each trimester of pregnancy (reference method) and intakes from both the food frequency questionnaire and the mean of the 3-day food diaries were compared in a sample of 130 participants from the control arm of an intervention study. RESULTS: Energy-adjusted Pearson's correlation coefficients ranged from 0.24 (riboflavin) to 0.59 (magnesium) and were all statistically significant (P < 0.05). The food frequency questionnaire tended to report higher energy and nutrient intakes compared to the food diaries. On average, 74% of participants were classified into the same ± 1 quartile and 7% into opposing quartiles by the two methods. CONCLUSIONS: Overall, our food frequency questionnaire showed good relative validity. We conclude that a single administration of a food frequency questionnaire is a valid tool for ranking women in accordance with their nutrient intakes during pregnancy.

[Development and validation of a new questionnaire to assess health care satisfaction and the device in stomized patients: espejo questionnaire].  

UK PubMed Central (United Kingdom)

OBJECTIVES: To develop a questionnaire to measure the satisfaction of stomatised patients with healthcare professionals and with the stomal device. METHODS: An initial review of the literature was performed and in meetings with experts, the most relevant items were selected. In a pilot study with patients that had been recently stomatised (three months from intervention), the comprehensibility and discriminatory ability of each item was tested. Items were eliminated on the grounds of frequent "no response" or low correlation with others on the provisional scale (determined by means of Cronbach's alpha). RESULTS: Following meetings with experts, 12 items were eliminated by reason of irrelevance or low frequency of use. Subsequently by means of administration of the questionnaire to a sample of 72 patients, five more items were selected for elimination. An analysis of the 13 items that remained confirmed an acceptable level of reliability (Cronbach's alpha of 0.917) and also the significant differences in the global scores between the patients who have had stoma for more than three months (higher satisfaction) and patients who had been recently stomatised. The items in the questionnaire referred to aspects of easy and comfort of use of the stoma, as well as satisfaction with information received and interaction with healthcare professionals from the point of view of the patient. CONCLUSIONS: This is the first questionnaire to measure satisfaction with healthcare professionals and the stomal device from the perspective of the stomatised patient. In a subsequent study the other properties of the measurement tool (validity responsiveness and longitudinal validation) will be evaluated.

International Physical Activity Questionnaire (IPAQ) and New Zealand Physical Activity Questionnaire (NZPAQ): A doubly labelled water validation  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Accurate measurement of physical activity is a pre-requisite for monitoring population health and for evaluating effective interventions. The International Physical Activity Questionnaire (IPAQ) is used as a comparable and standardised self-report measure of habitual physical activity of populations from different countries and socio-cultural contexts. The IPAQ has been modified to produce a New Zealand physical activity questionnaire (NZPAQ). The aim of this study was to validate the IPAQ and NZPAQ against doubly labelled water (DLW). Method: Total energy expenditure (TEE) was measured over a 15-day period using DLW. Activity-related energy expenditure (AEE) was estimated by subtracting the energy expenditure from resting metabolic rate and thermic effect of feeding from TEE. The IPAQ (long form) and NZPAQ (short form) were completed at the end of each 7-day period. Activity-related energy expenditure (IPAQAEE and NZPAQAEE) was calculated from each questionnaire and compared to DLWAEE. Results Thirty six adults aged 18 to 56 years (56% female) completed all measurements. Compared to DLWAEE, IPAQAEE and NZPAQAEE on average underestimated energy expenditure by 27% and 59%, respectively. There was good agreement between DLWAEE and both IPAQAEE and NZPAQAEE at lower levels of physical activity. However there was marked underestimation of questionnaire-derived energy expenditure at higher levels of activity. Conclusion Both the IPAQ and NZPAQ instruments have a demonstrated systematic bias toward underestimation of physical activity-related energy expenditure at higher levels of physical activity compared to DLW. Appropriate calibration factors could be used to correct for measurement error in physical activity questionnaires and hence improve estimation of AEE.

Validation issues in questionnaires for diagnosis and monitoring of gastroesophageal reflux disease in children.  

Science.gov (United States)

Pediatric gastroesophageal reflux disease (GERD) is common in infants and children; diagnosis is often based on symptom presentation. This paper reviews psychometric characteristics and approaches to validation of currently available pediatric GERD questionnaires. Patient-reported outcomes allow disease and treatment to be characterized in meaningful ways to patients and clinicians. Outcome measures must demonstrate reliability and validity for use in practice and in clinical trials. Reliability assesses the consistency of measures, whereas validity examines whether the instrument measures what it is purported to measure. Development of questionnaires for use with children also requires consideration regarding the respondent. Measures of pediatric GERD symptoms include the GERQ, GERQ-R, and GSQ. These measures have advantages and disadvantages with regard to feasibility, reliability, and validity. Questionnaires are lacking for children older than 4 years. PMID:16764789

Validation of the Finnish version of the SCOFF questionnaire among young adults aged 20 to 35 years  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background We tested the validity of the SCOFF, a five-question screening instrument for eating disorders, in a general population sample. Methods A random sample of 1863 Finnish young adults was approached with a questionnaire that contained several screens for mental health interview, including the SCOFF. The questionnaire was returned by 1316 persons. All screen positives and a random sample of screen negatives were invited to SCID interview. Altogether 541 subjects participated in the SCID interview and had filled in the SCOFF questionnaire. We investigated the validity of the SCOFF in detecting current eating disorders by calculating sensitivity, specificity, and positive and negative predictive values (PPV and NPV) for different cut-off scores. We also performed a ROC analysis based on these 541 persons, of whom nine had current eating disorder. Results The threshold of two positive answers presented the best ability to detect eating disorders, with a sensitivity of 77.8%, a specificity of 87.6%, a PPV of 9.7%, and a NPV of 99.6%. None of the subjects with current eating disorder scored zero points in the SCOFF. Conclusion Due to its low PPV, there are limitations in using the SCOFF as a screening instrument in unselected population samples. However, it might be used for ruling out the possibility of eating disorders.

Agreement, reliability and validity in 3 shoulder questionnaires in patients with rotator cuff disease  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Self-report questionnaires play an important role as outcome measures in shoulder research. Having an estimate of the measurement error of these questionnaires is of importance when assessing follow-up results after treatment and when planning intervention studies. The aim of this study was to cross-culturally adapt the Norwegian version of the OSS and WORC questionnaire and examine and compare agreement, reliability and construct validity of the disease-specific shoulder questionnaire WORC with two commonly used shoulder questionnaires, SPADI and OSS, in patients with rotator cuff disease. Methods 74 patients with rotator cuff disease were recruited from the outpatient clinic of the Physical Medicine and Rehabilitation Department at Ullevaal University Hospital in Oslo, Norway. A test-retest design was used, and the questionnaires were filled out by the patients at the clinic, with a one week interval between test administrations. Agreement (repeatability coefficient), reliability (ICC) and construct validity were examined and compared for WORC, SPADI and OSS. Results Reliability analysis was restricted to the 55 patients (51 ± 10 yrs) who reported no change between test administrations according to scoring on a global scale. The agreement, reliability and construct validity was moderate for all three questionnaires with ICC ranging from 0.83 to 0.85, repeatability coefficient from 16.1 to 19.7 and Spearman rank correlations between total scores from r = 0.57 to 0.69. There was a lower degree of floor and ceiling effects in SPADI compared to WORC and OSS. Conclusion We conclude that the agreement and reliability of the three shoulder questionnaires examined, WORC index, SPADI and OSS are acceptable and that differences between scores were small. The Norwegian version of the questionnaires is acceptable for assessing Norwegian-speaking patients with rotator cuff disease. The moderate agreement and construct validity should be taken into consideration when assessing follow-up results after treatment and in the planning of prospective studies.

Reliability and validity of the Korean standard pattern identification for stroke (K-SPI-Stroke) questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The present study was conducted to examine the reliability and validity of the ‘Korean Standard Pattern Identification for Stroke (K-SPI-Stroke)’, which was developed and evaluated within the context of traditional Korean medicine (TKM). Methods Between September 2006 and December 2010, 2,905 patients from 11 Korean medical hospitals were asked to complete the K-SPI-Stroke questionnaire as a part of project ' Fundamental study for the standardization and objectification of pattern identification in traditional Korean medicine for stroke (SOPI-Stroke). Each patient was independently diagnosed by two TKM physicians from the same site according to one of four patterns, as suggested by the Korea Institute of Oriental Medicine: 1) a Qi deficiency pattern, 2) a Dampness-phlegm pattern, 3) a Yin deficiency pattern, or 4) a Fire-heat pattern. We estimated the internal consistency using Cronbach’s ? coefficient, the discriminant validity using the means score of patterns, and the predictive validity using the classification accuracy of the K-SPI-Stroke questionnaire. Results The K-SPI-Stroke questionnaire had satisfactory internal consistency (??=?0.700) and validity, with significant differences in the mean of scores among the four patterns. The overall classification accuracy of this questionnaire was 65.2 %. Conclusion These results suggest that the K-SPI-Stroke questionnaire is a reliable and valid instrument for estimating the severity of the four patterns.

[Validation of a Spanish Short Version of the Minnesota Leisure Time Physical Activity Questionnaire (VREM)].  

UK PubMed Central (United Kingdom)

BACKGROUND: The aim of this study is to develop and validate a shorter version (VREM) of the Spanish version of the Minnesota leisure time Physical Activity Questionnaire (CAFM), in order to have a shorter physical activity questionnaire to be used in Primary Care. METHODS: Descriptive study of validation of a new physical activity measurement questionnaire. 200 patients older than 50, who visited one of 5 primary care centers in Barcelona for any reason were selected, with age-sex Catalonia's distribution. Two phases: first, VREM construction through items reduction. Second, validity of VREM against CAFM (gold standard) and test-retest reliability of VREM were analyzed, using kappa index and the intraclass correlation coefficient (ICC). RESULTS: 6 items were included in the VREM: Walking, Gardening, Sport/dancing, Climbing stairs, Shopping walking and Cleaning house. The interview using VREM lasted 5 minutes (standard deviation 2). Agreement between both questionnaires, using 4 levels of physical activity, was 95.5% (kappa=0.93). Test-retest reliability of the questionnaire was 92.5% (kappa=0.88). Using a continuous outcome in metabolic energy turnover (MET), VREM also proved to be valid and reliable (ICC=0.95 and ICC=0.96 respectively). CONCLUSION: This short version of CAFM has shown good validity and reliability in people ?50 years.

[Development and validation of a questionnaire to measure hospitals' social reputation].  

UK PubMed Central (United Kingdom)

OBJECTIVE: To design and validate a questionnaire (MeFio) to measure the social reputation of a hospital from patients' and citizens' perspective. MATERIAL AND METHODS: We performed a literature review to define the concept of a hospital's social reputation. Four nominal groups were conducted to set up the a priori factors of the MeFio questionnaire. These groups consisted of 47 managers and health professionals and 32 potential customers. Reactive items were identified and a pilot test was conducted to examine comprehension. A random sample of 385 subjects was selected. Ceiling and floor effects, internal consistency, reliability, and construct and criteria validity were analyzed. RESULTS: A total of 343 validated questionnaires (response rate 89%) were collected. The MeFio questionnaire has 21 items grouped into five factors. All items had an item-total correlation higher than 0.30. All factor loads were higher than 0.5; between 66.2% and 80.4% of the variance was explained and Cronbach's alpha was 0.7- 0.88. The construct-composite-reliability scores were higher than 0.7. Standardized scores in the convergent discriminant validity test were higher than 0.6. The factors explained 50% of the variability in satisfaction with the health care received (F = 66.5; p <0.001). CONCLUSION: The MeFio questionnaire is a valid and reliable tool to measure the five dimensions that define the reputation of a hospital in Spain.

Reliability and validity of two frequently used self-administered physical activity questionnaires in adolescents  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background To create and find accurate and reliable instruments for the measurement of physical activity has been a challenge in epidemiological studies. We investigated the reliability and validity of two different physical activity questionnaires in 71 adolescents aged 13–18 years; the WHO, Health Behaviour in Schoolchildren (HBSC) questionnaire, and the International Physical Activity Questionnaire (IPAQ, short version). Methods The questionnaires were administered twice (8–12 days apart) to measure reliability. Validity was assessed by comparing answers from the questionnaires with a cardiorespiratory fitness test (VO2peak) and seven days activity monitoring with the ActiReg, an instrument measuring physical activity level (PAL) and total energy expenditure (TEE). Results Intraclass correlation coefficients for reliability for the WHO HBSC questionnaire were 0.71 for frequency and 0.73 for duration. For the frequency question, there was a significant difference between genders; 0.87 for girls and 0.59 for boys (p 2peak were fair, ranging between 0.29 – 0.39. The WHO HBSC questionnaire measured against VO2peak for girls were acceptable, ranging between 0.30 – 0.55. Both questionnaires, except the walking question in IPAQ, showed a low correlation with PAL and TEE, ranging between 0.01 and 0.29. Conclusion These data indicate that the WHO HBSC questionnaire had substantial reliability and were acceptable instrument for measuring cardiorespiratory fitness, especially among girls. None of the questionnaires however seemed to be a valid instrument for measuring physical activity compared to TEE and PAL in adolescents.

End-of-life practices in Danish ICUs: development and validation of a questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Practices for withholding or withdrawing therapy vary according to professional, cultural and religious differences. No Danish-validated questionnaire examining withholding and withdrawing practices exists, thus the aim of this study was to develop and validate a questionnaire for surveying the views of intensive care nurses, intensivists, and primary physicians regarding collaboration and other aspects of withholding and withdrawing therapy in the ICU. Methods A questionnaire was developed on the basis of literature, focus group interviews with intensive care nurses and intensivists, and individual interviews with primary physicians. The questionnaire was validated in the following 3 phases: a qualitative test with 17 participants; a quantitative pilot test with 60 participants; and a survey with 776 participants. The validation process included tests for face and content validity (by interviewing participants in the qualitative part of the pilot study), reliability (by assessing the distribution of responses within the individual response categories), agreement (by conducting a test-retest, evaluated by paired analyses), known groups’ validity (as a surrogate test for responsiveness, by comparing two ICUs with a known difference in end-of-life practices), floor and ceiling effect, and missing data. Results Face and content validity were assessed as good by the participants in the qualitative pilot test; all considered the questions relevant and none of the participants found areas lacking. Almost all response categories were used by the participants, thus demonstrating the questionnaires ability to distinguish between different respondents, agreement was fair (the average test-retest agreement for the Likert scale responses was 0.54 (weighted kappa; range, 0.25-0.73), and known groups’ validity was proved by finding significant differences in level of satisfaction with interdisciplinary collaboration and in experiences of withdrawal decisions being unnecessarily postponed. Floor and ceiling effect was in accordance with other questionnaires, and missing data was limited to a range of 0-7% for all questions. Conclusions The validation showed good and fair areas of validity of the questionnaire. The questionnaire is considered a useful tool to assess the perceptions of collaboration and other aspects of withholding and withdrawing therapy practices in Danish ICUs amongst nurses, intensivists, and primary physicians.

Validation of the UFS-QOL-hysterectomy questionnaire: modifying an existing measure for comparative effectiveness research.  

UK PubMed Central (United Kingdom)

OBJECTIVE: The Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire, a validated patient-reported outcome measure of fibroid symptoms and health-related quality of life, was modified for use posthysterectomy. This study was conducted to psychometrically validate the UFS-QOL-Hysterectomy questionnaire for potential use in comparative effectiveness research to evaluate uterine fibroid treatments. METHODS: This multicenter prospective study enrolled premenopausal women aged 30 to 50 years with uterine fibroids who were scheduled for hysterectomy, myomectomy, or uterine fibroid embolization. All participants completed the UFS-QOL questionnaire and short form 36 health survey at baseline prior to treatment and 6 and 12 months postprocedure. Women with hysterectomy completed the UFS-QOL-Hysterectomy questionnaire during follow-up visits. Internal consistency reliability, discriminant and concurrent validity, and responsiveness were assessed. RESULTS: A total of 274 women were enrolled (107 uterine fibroid embolization, 61 myomectomy, and 106 hysterectomy) and 89 (83%), 55 (90%), and 91 (86%), respectively, completed the 12-month follow-up. The mean age was 43.2 (uterine fibroid embolization), 40.6 (myomectomy), and 44.5 (hysterectomy) years; 53%, 43%, and 37%, respectively, were black. Cronbach's alphas for the UFS-QOL-Hysterectomy questionnaire at 6 months ranged from 0.70 to 0.96 and from 0.66 to 0.95 at 12 months. Effect sizes ranged from 1.23 to 2.55, indicating that the UFS-QOL-Hysterectomy questionnaire was highly responsive. CONCLUSIONS: The UFS-QOL-Hysterectomy questionnaire is a valid and reliable patient-reported outcome measure of uterine fibroid treatment with hysterectomy and can be used in conjunction with the UFS-QOL questionnaire to compare patient-reported outcomes across treatments.

Validation of the Persian Version of the 40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Background: As a disease of motor nervous system (motor neuron disease), amyotrophic lateral sclerosis (ALS) has a great impact on several aspects of quality of life (QoL). Generic questionnaires of QoL do not address all the especial features of ALS and therefore translation and validation of disease specific questionnaires such as Amyotrophic Lateral Sclerosis Assessment Questionnaire 40-item (ALSAQ-40) is necessary for assessment of patients with different languages. The aim of this study was to review the validation of the Persian version of the ALSAQ-40.Methods: Meticulously translated ALSAQ-40 was completed by 21 ALS patients. Internal reliability was evaluated using Cronbach’s alpha coefficient and item-total correlation was also used to evaluate the correlation of each question with total score. Validity was evaluated through comparison with Amyotrophic Lateral Sclerosis Functional Rating Scale-revised (ALSFRS-r) and the36-Item Short Form Health Survey (SF-36).Results: Cronbach’s alpha coefficient was 0.91-0.96 for different scales of the ALSAQ-40. All the 40 questions of the questionnaire had correlation greater than 0.5. Correlation coefficient of all the related scales of the Persian version of ALSAQ-40, SF-36 and ALSFRS-r was greater than 0.59 with P value < 0.001.Conclusion: Measures of the Cronbach’s alpha coefficient and item-total correlation demonstrated reliability and consistency of the questionnaire, and correlation coefficients confirmed the validity of different items in the questionnaire. This study showed that the Persian version of the ALSAQ-40 is a reliable and valid questionnaire for the evaluation of QoL in ALS patients with Persian language.

The Comparative Validity of Interactive Multimedia Questionnaires to Paper-Administered Questionnaires for Beverage Intake and Physical Activity: Pilot Study  

Science.gov (United States)

Background Brief, valid, and reliable dietary and physical activity assessment tools are needed, and interactive computerized assessments (ie, those with visual cues, pictures, sounds, and voiceovers) can reduce administration and scoring burdens commonly encountered with paper-based assessments. Objective The purpose of this pilot investigation was to evaluate the comparative validity and reliability of interactive multimedia (IMM) versions (ie, IMM-1 and IMM-2) compared to validated paper-administered (PP) versions of the beverage intake questionnaire (BEVQ-15) and Stanford Leisure-Time Activity Categorical Item (L-Cat); a secondary purpose was to evaluate results across two education attainment levels. Methods Adults 21 years or older (n=60) were recruited to complete three laboratory sessions, separated by three to seven days in a randomly assigned sequence, with the following assessments–demographic information, two IMM and one paper-based (PP) version of the BEVQ-15 and L-Cat, health literacy, and an IMM usability survey. Results Responses across beverage categories from the IMM-1 and PP versions (validity; r=.34-.98) and the IMM-1 and IMM-2 administrations (reliability; r=.61-.94) (all Pquestionnaires were easy to complete, and relevant to participants' typical beverage choices and physical activity habits. Conclusions In general, less educated participants consumed more total beverage and SSB energy, and reported less engagement in physical activity. The IMM BEVQ-15 appears to be a valid and reliable measure to assess habitual beverage intake, although software familiarization may increase response accuracy. The IMM-L-Cat can be considered reliable and may have permitted respondents to more freely disclose actual physical activity levels versus the paper-administered tool. Future larger-scale investigations are warranted to confirm these possibilities.

Linguistic validation of translation of the Self-Assessment Goal Achievement (SAGA) questionnaire from English.  

UK PubMed Central (United Kingdom)

BACKGROUND: A linguistic validation of the Self-Assessment Goal Achievement (SAGA) questionnaire was conducted for 12 European languages, documenting that each translation adequately captures the concepts of the original English-language version of the questionnaire and is readily understood by subjects in the target population. METHODS: Native-speaking residents of the target countries who reported urinary problems/lower urinary tract problems were asked to review a translation of the SAGA questionnaire, which was harmonized among 12 languages: Danish, Dutch, English (UK), Finnish, French, German, Greek, Icelandic, Italian, Norwegian, Spanish, and Swedish. During a cognitive debriefing interview, participants were asked to identify any words that were difficult to understand and explain in their own words the meaning of each sentence in the questionnaire. The qualitative analysis was conducted by local linguistic validation teams (original translators, back translator, project manager, interviewer, and survey research expert). RESULTS: Translations of the SAGA questionnaire from English to 12 European languages were well understood by the participants with an overall comprehension rate across language of 98.9%. In addition, the translations retained the original meaning of the SAGA items and instructions. Comprehension difficulties were identified, and after review by the translation team, minor changes were made to 7 of the 12 translations to improve clarity and comprehension. CONCLUSIONS: Conceptual, semantic, and cultural equivalence of each translation of the SAGA questionnaire was achieved thus confirming linguistic validation.

Validation of activity questionnaires in patients with cystic fibrosis by accelerometry and cycle ergometry  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The objective of this study was to validate physical activity questionnaires for cystic fibrosis (CF) against accelerometry and cycle ergometry. Methods 41 patients with CF (12-42 years) completed the Habitual Activity Estimation Scale (HAES), the 7-Day Physical Activity Recall questionnaire (7D-PAR) and the Lipid Research Clinics questionnaire (LRC) and performed an incremental exercise test according to the Godfrey protocol up to volitional fatigue. Time spent in moderate and vigorous physical activity (MVPA) assessed objectively by accelerometry was related to the time spent in the respective activity categories by correlation analyses and calculating intraclass correlation coefficients (ICC). Furthermore, the results of the exercise test were correlated with the results of the questionnaires. Results Time spent in the categories 'hard','very hard' and 'hard & very hard' of the 7D-PAR (0.41 p = 0.002; VO2peak: r = 0.32, p = 0.041). Conclusions In conclusion, the activity categories 'hard' and 'very hard' of the 7D-PAR best reflected objectively measured MVPA. Since the association was at most moderate, the 7D-PAR may be selected to describe physical activity within a population. None of the evaluated questionnaires was able to generate valid physical activity data exercise performance data at the individual level. Neither did any of the questionnaires provide a valid assessment of aerobic fitness on an invidual level.

Structure Standardization, Validity and Reliability of Subjective Well-being Questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available AbstractObjectives: To design a short questionnaire on subjective well-being and the assessment of its validity and reliability. Method: Using references, a set of questions was gathered and constructed, and was assessed in two phases. In the first phase, it was randomly administered to 70 Mobarake Steel Complex personnel in Isfahan, Iran, and in the second phase it was administered to 40 personnel who had referred to a counseling center subsequent to a diagnosis of depressive disorder and anxiety via interview-as well as 166 non-referred personnel in a random manner. Internal consistency, content validity, diagnostic validity, reliability, cut-off points, sensitivity and specificity of the questionnaire and its measurement error were calculated using correlation, analysis of variance, independent t, discriminate analysis and factor analysis. Results: The results of factor analysis showed four sub-scales: vitality, life determination, neuroses, and stress-depression. Cronbach’s alpha for these four subscales was higher than 0.8. The difference between the normal and the patient group (p<0.0001) indicated the validity of the questionnaire. Cut-off point, sensitivity and specificity of this questionnaire were 1.9%, 67.5%, and 78% respectively. Conclusion: Considering its favorable psychometric features, this questionnaire could be used for research, diagnostic and treatment purposes.

Development and validation of a cancer awareness questionnaire for Malaysian undergraduate students of Chinese ethnicity.  

UK PubMed Central (United Kingdom)

OBJECTIVES: To describe the development and validation of a cancer awareness questionnaire (CAQ) based on a literature review of previous studies, focusing on cancer awareness and prevention. MATERIALS AND METHODS: A total of 388 Chinese undergraduate students in a private university in Kuala Lumpur, Malaysia, were recruited to evaluate the developed self-administered questionnaire. The CAQ consisted of four sections: awareness of cancer warning signs and screening tests; knowledge of cancer risk factors; barriers in seeking medical advice; and attitudes towards cancer and cancer prevention. The questionnaire was evaluated for construct validity using principal component analysis and internal consistency using Cronbach's alpha (?) coefficient. Test-retest reliability was assessed with a 10-14 days interval and measured using Pearson product-moment correlation. RESULTS: The initial 77-item CAQ was reduced to 63 items, with satisfactory construct validity, and a high total internal consistency (Cronbach's ?=0.77). A total of 143 students completed the questionnaire for the test-retest reliability obtaining a correlation of 0.72 (p<0.001) overall. CONCLUSIONS: The CAQ could provide a reliable and valid measure that can be used to assess cancer awareness among local Chinese undergraduate students. However, further studies among students from different backgrounds (e.g. ethnicity) are required in order to facilitate the use of the cancer awareness questionnaire among all university students.

Full Text Available AbstractObjectives: The aim of this study was to measure the reliability and validity of the Buss and Perry's Aggression Questionnaire. This ques-tionnaire includes 29 questions which was used by psychologists after being translated to Farsi.Method: In a cross-sectional study 492 18-22 years old students (248 male, 244 female) from Shiraz University, who were selected using the random-cluster sampling method, were evaluated using the Buss and Perry's Aggression Questionnaire. Data were analyzed using correlation coefficient, factor analysis and t-test.Results: Using factor analysis, the four factors of anger, physical and verbal aggression, resentment and suspicion were extracted. The test-retest reliability of this questionnaire was 0.78. Also, the comparison of these factors between males and females revealed that males scored significantly higher at anger (p<0.001), aggression (p<0.001) and suspicion (p<0.01). In addition, the high correlation of the factors with the total score of the questionnaire, the weak correlation of factors with each other and alpha coefficient scores is an indication of the adequacy and the practicality of this questionnaire for being used by researchers, professionals and psychologists in Iran. Conclusion: Buss and Perry’s Aggression Questionnaire has appropriate validity and reliability for being used by researchers and professionals.

The development and validation of the King's Sarcoidosis Questionnaire for the assessment of health status.  

UK PubMed Central (United Kingdom)

RATIONALE: Health status is impaired in patients with sarcoidosis. There is a paucity of tools that assess health status in sarcoidosis. The objective of this study was to develop and validate the King's Sarcoidosis Questionnaire (KSQ), a new modular health status measure. METHODS: Patients with sarcoidosis were recruited from outpatient clinics. The development of the questionnaire consisted of three phases: item generation; item reduction, Rasch analysis to create unidimensional scales and validation; repeatability testing. RESULTS: 207 patients with sarcoidosis (organ involvement: 184 lung, 54 skin, 45 eye disease) completed a 65-item preliminary questionnaire. 36 items were removed due to redundancy or poor fit to the Rasch model. The final version of the KSQ consisted of five modules (General health status, Lung, Skin, Eye, Medications). Internal consistency assessed with Cronbach's ? coefficient was 0.70-0.93 for KSQ modules. Concurrent validity of the Lung module was high compared with St George's Respiratory Questionnaire (r=-0.83) and moderate when compared to forced vital capacity (r=0.49). Concurrent validity with skin-specific and eye-specific measures ranged from r=-0.4 to 0.8. The KSQ was repeatable over 2 weeks (n=39), intraclass correlation coefficients for modules were 0.90-0.96. CONCLUSIONS: The KSQ is a brief, valid, self-completed health status measure for sarcoidosis. It can be used in the clinic to assess sarcoidosis from the patients' perspective.

Reliability and validity of a brief method to assess nociceptive flexion reflex (NFR) threshold.  

UK PubMed Central (United Kingdom)

UNLABELLED: The nociceptive flexion reflex (NFR) is a physiological tool to study spinal nociception. However, NFR assessment can take several minutes and expose participants to repeated suprathreshold stimulations. The 4 studies reported here assessed the reliability and validity of a brief method to assess NFR threshold that uses a single ascending series of stimulations (Peak 1 NFR), by comparing it to a well-validated method that uses 3 ascending/descending staircases of stimulations (Staircase NFR). Correlations between the NFR definitions were high, were on par with test-retest correlations of Staircase NFR, and were not affected by participant sex or chronic pain status. Results also indicated the test-retest reliabilities for the 2 definitions were similar. Using larger stimulus increments (4 mAs) to assess Peak 1 NFR tended to result in higher NFR threshold estimates than using the Staircase NFR definition, whereas smaller stimulus increments (2 mAs) tended to result in lower NFR threshold estimates than the Staircase NFR definition. Neither NFR definition was correlated with anxiety, pain catastrophizing, or anxiety sensitivity. In sum, a single ascending series of electrical stimulations results in a reliable and valid estimate of NFR threshold. However, caution may be warranted when comparing NFR thresholds across studies that differ in the ascending stimulus increments. PERSPECTIVE: This brief method to assess NFR threshold is reliable and valid; therefore, it should be useful to clinical pain researchers interested in quickly assessing inter- and intra-individual differences in spinal nociceptive processes.

Validity and reliability of the Brief TeamSTEPPS Teamwork Perceptions Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND AND PURPOSE: Teamwork is an essential component of hospital nursing quality and safety. The purpose of this study is to test the validity and reliability of the Brief TeamSTEPPS Teamwork Perception Questionnaire (Brief T-TPQ). METHODS: The 20-item questionnaire was completed electronically by a sample (N = 456) of hospital bedside nurses and tested for reliability and validity. RESULTS: The survey demonstrated internal consistency reliability of .83-.94 with a total survey reliability of .93. A hierarchical relationship three factor subscale structure was confirmed, explaining 64% of the variance and acceptable factor loadings. A secondary five-factor structure revealed statistically and conceptually coherent skills and behaviors sub-subscales. Discriminant validity was demonstrated with self-esteem and control over practice. CONCLUSIONS: The 20-item Brief T-TPQ is a valid and reliable survey to measure hierarchical teamwork relationships as well as teamwork skills and behaviors.

Reliability and validity of the adapted Greek version of scoliosis research society – 22 (SRS-22) questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The SRS-22 is a valid instrument for the assessment of the health related quality of life of patients with Idiopathic scoliosis. The SRS-22 questionnaire was developed in USA and has been widely used in the English speaking countries. Recently it has been translated and validated in many other languages. The purpose of this study is to evaluate the reliability and validity of the adapted Greek version of the refined Scoliosis Research Society-22 Questionnaire. Methods Following the steps of cross – cultural adaptation the adapted Greek version of the SRS-22 questionnaire and a validated Greek version of the SF-36 questionnaire were mailed to 68 patients treated surgically for Idiopathic Scoliosis. 51 out of the 68 patients returned the 1st set of questionnaires, while a second set was emailed to 30 randomly selected patients of the first time responders. 20 out of the 30 patients returned the 2nd set. The mean age at the time of operation was16,2 years and the mean age at the time of evaluation was 21,2 years. Descriptive statistics for content analysis were calculated. Reliability assessment was determined by estimating Cronbach's ? and intraclass correlation coefficient (ICC) respectively. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36 questionnaire using Pearson's Correlation Coefficient (r). Results The calculated Cronbach's ? of internal consistency for three of the corresponding domains (pain 0.85; mental health 0.87; self image 0.83) were very satisfactory and for two domains (function/activity 0.72 and satisfaction 0.67) were good. The ICC of all domains of SRS-22 questionnaire was high (ICC>0.70), demonstrating very satisfactory or excellent test/retest reproducibility. Considering concurrent validity all correlations were found to be statistically significant at the 0.01 level among related domains and generally demonstrated high correlation coefficient. Conclusion The adapted Greek version of the SRS-22 questionnaire is valid and reliable and can be used for the assessment of the outcome of the treatment of the Greek speaking patients with idiopathic scoliosis.

Reliability and validity of a school-based physical activity questionnaire.  

UK PubMed Central (United Kingdom)

PURPOSE: To determine the reliability and validity of the School Health Action, Planning and Evaluation System (SHAPES) physical activity questionnaire, a machine-readable questionnaire designed to collect data from all students in a school from grades 6 to 12 and to provide feedback to the school for planning and evaluation. METHODS: Study 1 assessed test-retest reliability by administering the questionnaire twice, 1 wk apart to 2812 students in grades 9-12. Study 2 assessed criterion validity using MTI accelerometers worn consecutively for 7 d, and measured height and weight (N = 67, grades 6-12). RESULTS: The overall kappa/weighted kappa coefficient for the 1-wk test-retest reliability of the questionnaire items indicated moderate agreement (mean 0.57 +/- 0.24). Self-reported and accelerometer-measured average daily time spent performing moderate to vigorous physical activity were significantly correlated (Spearman r = 0.44, P < 0.01); however, students tended to overreport physical activity. Height and weight were not consistently over- or underreported. Self-reported and measured body mass index were significantly correlated (Spearman r = 0.90, P < 0.001). Classification of weight status by body mass index was similar using self-reported values compared with measured values. CONCLUSION: The findings of these studies suggest that the SHAPES physical activity questionnaire has acceptable reliability and validity and is suitable for use in large-scale school-based data collections for child and adolescent populations.

Validation of an adapted arabic version of fibromyalgia syndrome impact questionnaire.  

UK PubMed Central (United Kingdom)

Fibromyalgia (FM) is the most common chronic pain syndrome encountered in medical practice, affecting females more than males, and the estimated prevalence of FM in Egypt is 1.3 %. The aim was to translate and adapt the Fibromyalgia Impact Questionnaire (FIQ) into Arabic and assess reliability and validity. The Arabic version of Fibromyalgia Impact Questionnaire (FIQ-A) was adapted following the forward/backward translation approach. Fifty-one female patients with FM were studied to assess psychometric properties of the FIQ-A. Reliability was analyzed by the correlation coefficient between test and retest. Internal consistency was checked by the Cronbach's alpha coefficient. Construct validity was assessed comparing FIQ-A with Health Assessment Questionnaire (HAQ), Health Assessment Questionnaire of Fibromyalgia (FHAQ), The Medical Outcome Survey Short-Form-36 (SF-36), and the Total Visual Analog Scale (TVAS) for FM symptom, and feasibility was assessed by the time taken in completing the FIQ-A and the proportion of patients completed the questionnaire. Patients studied were 33.2 ± 9.8 years old. Translation was concordant. Adaptation affected 4 sub-items of physical function. Test-retest correlation coefficient was 0.89 for total FIQ-A and Cronbach's alpha was 0.76. Excellent to good statistically significant correlations (p < 0.05) were found between the FIQ-A items and HAQ, FHAQ, and SF-36. The FIQ-A is a reliable, valid for measuring health status and physical function in Arabic-speaking FM patients.

Clinical validation of a quality of life questionnaire in angina pectoris patients.  

Science.gov (United States)

Angina pectoris impairs patients' quality of life. In order to assess its impact on quality of life, a questionnaire was developed using a literature review and interviews with patients and clinicians. It consisted of a general profile (SF-36) which measured functional status, well-being, perceived health, and a specific index, the Angina Pectoris Quality of Life Questionnaire, supplemented by new items. The acceptability, internal consistency reliability and clinical validity of this 70-item questionnaire were analysed in a cross-sectional study. Of 197 coronary patients approached, 93% (n = 184) agreed to participate and 86% (n = 170) returned the mailed questionnaire. Mean age of patients was 67 years (+/- 10); 79% were male and 70% were retired. Sixty patients were asymptomatic and 110 reported anginal crises (Canadian Cardiovascular Society Classification: class I: 48; II: 37; III: 13; IV: 0; V: 12). Globally, angina pectoris was found to affect each quality of life concept measured: physical functioning, well-being, and perceived health. Quality of life profiles worsened in accordance with increasing severity of the condition, as stratified by angina pectoris class. Asymptomatic patients reported better general and specific profiles. These results support the feasibility and usefulness of evaluating quality of life using the questionnaire. The validation of the data is very encouraging and enables the questionnaire to be used in clinical trials. PMID:8881847

Development and validation of an illustrated questionnaire to evaluate disabilities of the upper limb.  

Science.gov (United States)

We have developed an illustrated questionnaire, the Hand20, comprising 20 short and easy-to-understand questions to assess disorders of the upper limb. We have examined the usefulness of this questionnaire by comparing reliability, validity, responsiveness and the level of missing data with those of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. A series of 431 patients with disorders of the upper limb completed the Hand20 and the Japanese version of the DASH (DASH-JSSH) questionnaire. The norms for Hand20 scores were determined in another cross-sectional study. Most patients had no difficulty in completing the Hand20 questionnaire, whereas the DASH-JSSH had a significantly higher rate of missing data. The standard score for the Hand20 was smaller than the reported norms for the DASH. Our study showed that the Hand20 questionnaire provided validation comparable with that of the DASH-JSSH. Explanatory illustrations and short questions which were easy-to-understand led to better rates of response and fewer missing data, even in elderly individuals with cognitive deterioration.

Standard values and relationship-specific validity of the Bielefeld Relationship Expectations Questionnaire (BFPE)  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The Bielefeld Partnership Expectations Questionnaire (BFPE) is a tool to assess attachment in the romantic relationships of adults. The attachment styles are operationalized as configuration patterns of scale scores. While convergent validity has already been investigated, discriminant validity is still lacking confirmation. Methods The present sample (n = 1509) is representative for the German population aged 18 to 50. The mean age was 34.6 years. Most of the participants lived in a relationship (77.3 %). Discriminant validity was analyzed using a marital quality questionnaire (PFB), a social support questionnaire (F-Soz-U K-14), and a life satisfaction questionnaire (FLZ). Results All the BFPE scales have a satisfying internal consistency between r = .79 and .86. Those individuals who showed a secure pattern, i.e. increased "Readiness for Self-Disclosure" and "Conscious Need for Care" as well as reduced "Fear of Rejection" experienced their partner as socially supportive, reported higher marital quality in all of its facets, and were more satisfied within the life-domains "family/children" and "relationship/sexuality". Standard values for each scale are presented. Conclusions The BFPE has repeatedly been verified as a short, reliable, and valid instrument applicable to research practice with healthy individuals as well as within clinical contexts.

[Validation of the SCOFF questionnaire for screening the eating behaviour disorders of adolescents in school].  

UK PubMed Central (United Kingdom)

OBJECTIVE: To determine the internal consistency and criteria validity of the SCOFF questionnaire for screening adolescent eating behaviour disorders. DESIGN: Validation study with stochastic sampling. SETTING: Three schools at Bucaramanga, Colombia. PARTICIPANTS: 241 students selected at random from 1595 possible ones. MAIN INTERVENTIONS: SCOFF questionnaire and semi-structured CIDI interview, administered independently. MAIN MEASUREMENTS: Social and personal details, Cronbach's alpha, sensitivity analysis, specificity, forecast values, Cohen mean kappa test, and ROC curve. RESULTS: Sensitivity found was 81.9% (95% CI, 70.7-89.7) and specificity, 78.7% (95% CI, 71.7-84.6). The area under the ROC curve was 0.8596 (95% CI, 0.8108-0.9084); the Cronbach's alpha test, 0.436, and the Cohen mean kappa, 0.554 (95% CI, 0.425-0.683). CONCLUSIONS: The SCOFF questionnaire is an acceptable alternative for screening groups of adolescents because of its simplicity and speed of administration.

CVTresh: R Package for Level-Dependent Cross-Validation Thresholding  

Directory of Open Access Journals (Sweden)

Full Text Available The core of the wavelet approach to nonparametric regression is thresholding of wavelet coefficients. This paper reviews a cross-validation method for the selection of the thresholding value in wavelet shrinkage of Oh, Kim, and Lee (2006), and introduces the R package CVThresh implementing details of the calculations for the procedures.This procedure is implemented by coupling a conventional cross-validation with a fast imputation method, so that it overcomes a limitation of data length, a power of 2. It can be easily applied to the classical leave-one-out cross-validation and K-fold cross-validation. Since the procedure is computationally fast, a level-dependent cross-validation can be developed for wavelet shrinkage of data with various sparseness according to levels.

Development and validation of a questionnaire to assess delay in treatment for breast cancer  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background This study reports the reliability and validity of a questionnaire designed to measure the time from detection of a breast cancer to arrival at a cancer hospital, as well as the factors that are associated with delay. Methods The proposed questionnaire measures dates for estimation of the patient, provider and total intervals from detection to treatment, as well as factors that could be related to delays: means of problem identification (self-discovery or screening), the patients’ initial interpretations of symptoms, patients’ perceptions of delay, reasons for delay in initial seeking of medical care, barriers perceived to have caused provider delay, prior utilisation of health services, use of alternative medicine, cancer-screening knowledge and practices, and aspects of the social network of support for medical attention. The questionnaire was assembled with consideration for previous research results from a review of the literature and qualitative interviews of patients with breast cancer symptoms. It was tested for face validity, content validity, reliability, internal consistency, convergent and divergent validity, sensitivity and specificity in a series of 4 tests with 602 patients. Results The instrument showed good face and content validity. It allowed discrimination of patients with different types and degrees of delay, had quite good reliability for the time intervals (with no significant mean differences between the two measurements), and fairly good internal consistency of the item dimensions (with Cronbach’s alpha values for each dimension between 0.42 and 0.85). Finally, sensitivity and specificity were 74.68% and 48.81%, respectively. Conclusions To the best of our knowledge, this is the first published report of the development and validation of a questionnaire for estimation of breast cancer delay and its correlated factors. It is a valid, reliable and sensitive instrument.

Foi originalmente desenvol (more) vido no contexto croata, de acordo com a perspectiva teórica de Mayer e Salovey (1997), tendo sido traduzido para inglês e apresentado, em 2001, no 7th European Congress of Psychology, em Londres. São apresentadas as qualidades psicométricas e as relações do ESCQ com outros constructos relevantes, nos contextos Croata, Português, Finlandês, Sueco, Eslove­no, Espanhol e Japonês, utilizando amostras­?alvo de estudantes do ensino secun­dário e universitário, bem como de sujeitos mais velhos (trabalhadores e supervi­sores de empresas), tendo evidenciado bons valores de validade de constructo, convergente, divergente e concorrente. Contudo, o valor de alpha de Cronbach da subescala CLE exige melhoria, enfatizando a necessidade de prosseguir os estudos de validade do ESCQ. Abstract in english This article discusses the cross-cultural validation of the Emotional Skills and Competence Questionnaire (ESCQ), which consists of 45 items divided into three subscales - (i) perceiving and understanding emotion (PU), (ii) expressing and labelling emotion (EL), and (iii) managing and regulating emotion (MR) - and is classified as a ?trait emotional intelligence? or ?perceived emotional intelligence? measure. Originally, it was developed in Croatian settings using a t (more) heoretical framework from the emotional intelligence model (Mayer & Salovey, 1997), but it has already been translated into English and presented in 2001 at the 7th European Congress of Psychology in London. The psychometric qualities and the relations of ESCQ with several relevant constructs in Croatian, Portuguese, Finnish, Swedish, Slovene, Spanish, and Japanese contexts are here presented, using target samples of mainly high school and university students, as well as older subjects (workers and supervisors), highlighting construct, convergent, divergent and concurrent validity. However, the Cronbach alpha of the MRscale needs improvement, stressing the need to further pursue the validity studies of the ESCQ.

Development and validation of diabetes empowerment questionnaire in Iranian people with type 2 diabetes.  

UK PubMed Central (United Kingdom)

BACKGROUND: Diabetes self-management education programmes which have been reported to improve the self-efficacy of diabetic people can lead to their empowerment. Specialized diabetes nurses also play a fundamental role in empowering patients with diabetes through improving their knowledge and self-care. AIM: The purpose of this study was to develop a valid and reliable questionnaire to measure empowerment in Iranian people with type 2 diabetes. METHODS: Important subscales of patient empowerment were identified by an expert panel. The subscales included active self-care, coping with personal and social concerns, basic knowledge related to diabetes management and patient-physician communication. Questions related to each subscale were generated and the expert panel renewed the questionnaire to ensure relevance and clarity of the items. Patient focus groups were conducted to establish the face validity of the questionnaire. The final questionnaire consisted of 15 items organized in three subscales. In a population-based study, a sample of 378 people with type 2 diabetes was recruited. Reliability coefficient (Cronbach's ?) was calculated for all of the subscales. Convergent validity was assessed by Pearson's product moment correlation. The scree test was used to select significant subscales. FINDINGS: Two hundred forty-seven female and 131 male subjects with type 2 diabetes filled out the questionnaire. Three subscales were derived from factor analysis considering item-component loading of 0.4 as significant: 'active self-care' (Cronbach's ?: 0.78), 'basic knowledge related to diabetes management' (Cronbach's ?: 0.72) and 'coping with personal and social concerns' (Cronbach's ?: 0.51). The scree plot of the eigenvalues of 15 items proposed three subscale solutions. Internal consistency reliabilities for the three subscales were acceptable (?: 0.51-0.78). CONCLUSIONS: The Diabetes Empowerment Questionnaire is a reliable and valid tool to assess patient empowerment in Iranian people with type 2 diabetes.

Family physicians’ diagnostic gut feelings are measurable: construct validation of a questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Family physicians perceive that gut feelings, i.e. a ‘sense of reassurance’ or a ‘sense of alarm’, play a substantial role in diagnostic reasoning. A measuring instrument is desirable for further research. Our objective is to validate a questionnaire measuring the presence of gut feelings in diagnostic reasoning. Methods We constructed 16 case vignettes from real practice situations and used the accompanying ‘sense of reassurance’ or the ‘sense of alarm’ as reference labels. Based on the results of an initial study (26 family physicians), we divided the case vignettes into a group involving a clear role for the sense of reassurance or the sense of alarm and a group involving an ambiguous role. 49 experienced family physicians evaluated each 10 vignettes using the questionnaire. Construct validity was assessed by testing hypotheses and an internal consistency procedure was performed. Results As hypothesized we found that the correlations between the reference labels and corresponding items were high for the clear-case vignettes (0.59 – 0.72) and low for the ambiguous-case vignettes (0.08 – 0.23). The agreement between the classification in clear sense of reassurance, clear sense of alarm and ambiguous case vignettes as derived from the initial study and the study population’s judgments was substantial (Kappa = 0.62). Factor analysis showed one factor with opposites for sense of reassurance and sense of alarm items. The questionnaire’s internal consistency was high (0.91). We provided a linguistic validated English-language text of the questionnaire. Conclusions The questionnaire appears to be valid. It enables quantitative research into the role of gut feelings and their diagnostic value in family physicians’ diagnostic reasoning.

Validating an alternate version of the chewing function questionnaire in partially dentate patients  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The aim of this study was to investigate the dimensionality, reliability, and validity of an alternate version of the chewing function questionnaire in partially dentate patients in Japan. Methods Subjects were partially dentate patients who attended the prosthodontic clinic at Tokyo Medical and Dental University (N = 491, 71% women, mean age (± SD): 63.0 ± 11.5 years). The questionnaire asked each subject to rate his or her ability to chew 20 common Japanese foods. For each individual, responses were combined to yield a chewing function summary score, with higher scores indicating better self-reported chewing ability. We used exploratory factor analysis to investigate the scores' dimensionality. For validity assessment, we computed the correlations between the chewing function score and oral health-related quality of life (OHRQoL, as measured by the Japanese 14-item Oral Health Impact Profile (OHIP-14)) Internal consistency of scores and test-retest reliability were investigated by asking a subset of subjects (N = 62) to complete the questionnaire twice, 2 weeks apart. Results Exploratory factor analysis provided some evidence that self-reported chewing ability can be characterized by a summary score as the original authors suggest. Support for the validity of chewing function scores using the alternate version of the questionnaire was derived from correlations with OHIP-14 scores (r = -0.46, 95% confidence interval (CI): -0.53 to -0.39); thus, better chewing ability was associated with less impaired OHRQoL. Internal consistency was 'satisfactory,' with a Cronbach's alpha of 0.90 (lower limit of 95% CI: 0.89). The test-retest reliability was 'good,' with an intraclass correlation coefficient of 0.69 (95% CI: 0.56 to 0.82). Conclusion The alternate version of the chewing function questionnaire can be used as a stand-alone instrument because of the demonstrated reliability and validity of scores obtained using the questionnaire in partially dentate patients.

Development and initial validation of the Perceptions of Parental Illness Questionnaire (PPIQ).  

UK PubMed Central (United Kingdom)

The Perceptions of Parental Illness Questionnaire was developed based on interviews with 15 adolescents with a parent with multiple sclerosis and refined using cognitive interviews. In total, 104 adolescents with a parent with multiple sclerosis then completed the Perceptions of Parental Illness Questionnaire and adjustment measures at two time points 6 months apart. Principal component analysis resulted in 11 Perceptions of Parental Illness Questionnaire sub-scales. Mixed-effect models showed that adolescents' perceptions of parental multiple sclerosis at baseline rather than disease severity were associated with their psychosocial well-being 6 months later. The results indicate that Perceptions of Parental Illness Questionnaire may be a reliable and valid measure of adolescents' representations of parents' multiple sclerosis. Further studies are needed to replicate these findings with other illness groups.

Validation of edible taste strips for identifying PROP taste recognition thresholds.  

UK PubMed Central (United Kingdom)

OBJECTIVES/HYPOTHESIS: The purpose of this study was to validate the use of edible taste strips for measuring taste recognition thresholds for the bitter-tasting compound 6-n-propylthiouracil (PROP). STUDY DESIGN: Taste recognition thresholds for PROP were obtained by two separate methods. Thresholds were also identified in subjects whose airflow through the nose was blocked. Threshold values were then compared to genotype analysis of the TAS2R38 taste receptor, which is the major determinant for the detection of PROP. METHODS: Edible taste strips were used to examine taste recognition thresholds for PROP. Thresholds were determined by the method of ascending limits and by the method of reversals. Single nucleotide polymorphism analysis of the TAS2R38 gene was used to identify PROP taster status. RESULTS: Taste recognition thresholds for PROP formed two distributions. Thresholds for one group varied from 4 to 219 nmol and represented PROP tasters. The second group could not detect the bitter taste of PROP at ?800 nmol and represented PROP nontasters. The method of ascending limits and the method of reversals yielded similar threshold results. The expression of a PAV allele permitted detection of PROP, but AVI homozygotes could not detect the bitter taste of PROP. CONCLUSIONS: Edible taste strips were successfully used to detect PROP thresholds at values equal to or lower than those obtained in previous studies using PROP solutions or PROP-impregnated filter papers. This study provides validity evidence for the use of edible taste strips for identifying PROP in the human population.

Validation of the spanish version of the multiple sclerosis international quality of life (musiqol) questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The Multiple Sclerosis International Quality Of Life (MusiQoL) questionnaire, a 31-item, multidimensional, self-administrated questionnaire that is available in 14 languages including Spanish, has been validated using a large international sample. We investigated the validity and reliability of the Spanish version of MusiQoL in Spain. Methods Consecutive patients with different types and severities of multiple sclerosis (MS) were recruited from 22 centres across Spain. All patients completed the MusiQoL questionnaire, the 36-Item Short Form (SF-36) health survey, and a symptoms checklist at baseline and 21 days later. External validity, internal consistency, reliability and reproducibility were tested. Results A total of 224 Spanish patients were evaluated. Dimensions of MusiQoL generally demonstrated a high internal consistency (Cronbach's alpha: 0.70-0.92 for all but two MusiQoL domain scores). External validity testing revealed that the MusiQoL index score correlated significantly with all SF-36 dimension scores (Pearson's correlation: 0.46-0.76), reproducibility was satisfactory (intraclass correlation coefficient: 0.60-0.91), acceptability was high, and the time taken to complete the 31-item questionnaire was reasonable (mean [standard deviation]: 9.8 [11.8] minutes). Conclusions The Spanish version of the MusiQoL questionnaire appears to be a valid and reliable instrument for measuring quality of life in patients with MS in Spain and constitutes a useful instrument to measure health-related quality of life in the clinical setting.

Translation and validation of the Danish version of the Patient Rated Wrist Evaluation questionnaire.  

UK PubMed Central (United Kingdom)

Abstract The need for validated outcome measures is increasing. The purpose is to translate and validate the Patient Rated Wrist Evaluation (PRWE) in Danish. Translation was done by an expert panel followed by evaluation of a lay panel and a field test on 10 patients. Sixty patients with wrist fractures were included. Both lay panel comments and field test revealed issues not dealt with by the expert panel, and a final version of the Danish PRWE was made. The validation process then continued and reliability results. were presented as Cronbach's alpha = 0.94, describing the homogeneity and the intraclass correlation coefficient = 0.88 and difference of mean = 5.7 (CI = 1.12-10.37, p = 0.017), describing the concordance of the results. Convergent validity at first and last control was for pain, 0.51 and 0.46, and physical mobility, 0.56 and 0.64, respectively, describing the correlation with a gold standard questionnaire. A minor floor effect was noticed, but not enough to indicate a lack of sensitivity of the PRWE. Effect size, the ability to measure sensitivity to change, was 0.62, also described as responsiveness. The translation resulted in a questionnaire that represents correct easy-understandable Danish. It is concluded that the modified Danish version is a valid questionnaire for patients with wrist fractures.

Spanish validation of Bad Sobernheim Stress Questionnaire (BSSQ (brace).es) for adolescents with braces.  

UK PubMed Central (United Kingdom)

BACKGROUND: As a result of scientific and medical professionals gaining interest in Stress and Health Related Quality of Life (HRQL), the aim of our research is, thus, to validate into Spanish the German questionnaire Bad Sobernheim Stress Questionnaire (BSSQ) (mit Korsett), for adolescents wearing braces. METHODS: The methodology used adheres to literature on trans-cultural adaptation by doing a translation and a back translation; it involved 35 adolescents, ages ranging between 10 and 16, with Adolescent Idiopathic Scoliosis (AIS) and wearing the same kind of brace (Rigo System Chêneau Brace). The materials used were a socio-demographics data questionnaire, the SRS-22 and the Spanish version of BSSQ(brace).es. The statistical analysis calculated the reliability (test-retest reliability and internal consistency) and the validity (convergent and construct validity) of the BSSQ (brace).es. RESULTS: BSSQ(brace).es is reliable because of its satisfactory internal consistency (Cronbach's alpha coefficient was 0.809, p < 0.001) and temporal stability (test-retest method with a Pearson correlation coefficient of 0.902 (p < 0.01)).It demonstrated convergent validity with SRS-22 since the Pearson correlation coefficient was 0.656 (p < 0.01). By undertaking an Exploratory Principal Components Analysis, a latent structure was found based on two Components which explicate the variance at 60.8%. CONCLUSIONS: BSSQ (brace).es is reliable and valid and can be used with Spanish adolescents to assess the stress level caused by the brace.

[Validity and realibility of the Culture of Quality Health Services questionnaire in Mexico.  

UK PubMed Central (United Kingdom)

INTRODUCTION: Patient Safety is a major public health problem worldwide and is responsibility of all those involved in health care. Establishing a Safety Culture has proved to be a factor that favors the integration of work teams, communication and construction of clear procedures in various organizations. Promote a culture of safety depends on several factors, such as organization, work unit and staff. Objective assessment of these factors will help to identify areas for improvement and establish strategic lines of action. OBJETIVE: To adapt, validate and calibrate the questionnaire Culture of Quality in Health Services (CQHS) in Mexican population. MATERIAL AND METHODS: A cross with a stratified representative sample of 522 health workers. The questionnaire was translated and adapted from Singer's. Content was validated by experts, internal consistency, confirmatory factorial validity and item calibration with Samejima's Graded Response Model. RESULTS: Convergent and divergent construct validity was confirmed from the CQHS, item calibration showed that the questionnaire is able to discriminate between patients and represent different levels of the hypothesized dimensions with greater accuracy and lower standard error. CONCLUSIONS: The CQHS is a valid and reliable instrument to assess patient safety culture in hospitals in Mexico.

Development and initial validation of the Influences on Patient Safety Behaviours Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: Understanding the factors that make it more or less likely that healthcare practitioners (HCPs) will perform certain patient safety behaviors is important in developing effective intervention strategies. A questionnaire to identify determinants of HCP patient safety behaviors does not currently exist. This study reports the development and initial validation of the Influences on Patient Safety Behaviors Questionnaire (IPSBQ) based on the Theoretical Domains Framework. METHODS: Two hundred and thirty-three HCPs from three acute National Health Service Hospital Trusts in the United Kingdom completed the 34-item measure focusing on one specific patient safety behavior (using pH as the first line method for checking the position of a nasogastric tube). Confirmatory factor analysis (CFA) was undertaken to generate the model of best fit. RESULTS: The final questionnaire consisted of 11 factors and 23 items, and CFA produced a reasonable fit: chi2 (175) = 345.7, p < 0.001; CMIN/DF = 1.98; GFI = 0.90 and RMSEA = 0.06, as well as adequate levels of discriminant validity, and internal consistency (r = 0.21 to 0.64). CONCLUSIONS: A reliable and valid theoretically underpinned measure of determinants of HCP patient safety behavior has been developed. The criterion validity of the measure is still unknown and further work is necessary to confirm the reliability and validity of this measure for other patient safety behaviors.

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVE: The aim of the study was to validate the multimedia version of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis II Questionnaire in Portuguese language. MATERIAL AND METHODS: The sample comprised 30 patients with signs and symptoms of temporomandibular disorders (TMD), evaluated at the Orofacial Pain Control Center of the Dental School of the University of Pernambuco, Brazil, between April and June 2006. Data collection was performed using the following instruments: Simplifed Anamnestic Index (SAI) and RDC/TMD Axis II written version and multimedia version. The validation process consisted of analyzing the internal consistency of the scales. Concurrent and convergent validity were evaluated by the Spearman's rank correlation. In addition, test and analysis of reproducibility by the Kappa weighted statistical test and Spearman's rank correlation test were performed. RESULTS: The multimedia version of the RDC/TMD Axis II questionnaire in Portuguese was considered consistent (Crombrach alpha = 0.94), reproducible (Spearman 0.670 to 0.913, p<0.01) and valid (p<0.01). CONCLUSION: The questionnaire showed valid and reproducible results, and represents an instrument of practical application in epidemiological studies of TMD in the Brazilian population.

Systematic Development and Validation of a Theory-Based Questionnaire to Assess Toddler Feeding.  

UK PubMed Central (United Kingdom)

This paper describes the development and validation of a 27-item caregiver-reported questionnaire on toddler feeding. The development of the Toddler Feeding Behavior Questionnaire was based on a theory of interactive feeding that incorporates caregivers' responses to concerns about their children's dietary intake, appetite, size, and behaviors rather than relying exclusively on caregiver actions. Content validity included review by an expert panel (n = 7) and testing in a pilot sample (n = 105) of low-income mothers of toddlers. Construct validity and reliability were assessed among a second sample of low-income mothers of predominately African-American (70%) toddlers aged 12-32 mo (n = 297) participating in the baseline evaluation of a toddler overweight prevention study. Internal consistency (Cronbach's ?: 0.64-0.87) and test-retest (0.57-0.88) reliability were acceptable for most constructs. Exploratory and confirmatory factor analyses revealed 5 theoretically derived constructs of feeding: responsive, forceful/pressuring, restrictive, indulgent, and uninvolved (root mean square error of approximation = 0.047, comparative fit index = 0.90, standardized root mean square residual = 0.06). Statistically significant (P < 0.05) convergent validity results further validated the scale, confirming established relations between feeding behaviors, toddler overweight status, perceived toddler fussiness, and maternal mental health. The Toddler Feeding Behavior Questionnaire adds to the field by providing a brief instrument that can be administered in 5 min to examine how caregiver-reported feeding behaviors relate to toddler health and behavior.

Validation of the Body Dysmorphic Disorder Questionnaire in a community sample of Swedish women.  

UK PubMed Central (United Kingdom)

Body Dysmorphic Disorder (BDD) is characterized by a distressing and impairing preoccupation with a nonexistent or slight defect in appearance. Patients with the disorder present to both psychiatric and non-psychiatric physicians. A few studies have assessed BDD prevalence in the general population and have shown that the disorder is relatively common. To date, no BDD assessment instruments have been validated in the general population. Our aim was to validate a brief self-screening instrument, the Body Dysmorphic Disorder Questionnaire (BDDQ), in a female community sample. The BDDQ was translated into Swedish and filled out by 2891 women from a randomly selected community sample. The questionnaire was validated in a subsample of 88 women, using the Structured Clinical Interview for DSM-IV (SCID) together with clinical assessment as the gold standard. In the validation subsample, the BDDQ showed good concurrent validity, with a sensitivity of 94%, a specificity of 90% and a likelihood ratio of 9.4. The questionnaire can therefore be of value when screening for BDD in female populations.

[Validation in Spain of the quality of life questionnaire PROSQOLI in patients with advanced prostate cancer].  

UK PubMed Central (United Kingdom)

OBJECTIVES: Validation of the PROSQOLI questionnaire adapted to Spanish, pursing an instrument to evaluate, in the common clinical practice, the quality of life in patients with locally advanced or disseminated prostate cancer in our country. MATERIAL AND METHODS: A cross-sectional prospective study was designed in 750 patients (150 centers) with disseminated or locally advanced prostate cancer (TNM criterion) who came to the scheduled check-up. Socio-demographic and clinical data of the participants were collected. The subjects filled out the PROSQOLI and EQ-5D questionnaires. The analysis included 561 cases that met the selection criteria. The psychometric characteristics (feasibility, validity and reliability) of the adapted PROSQOLI questionnaire were studied. RESULTS: Mean age was 73.63 (7.59) years. A total of 72.01% of the participants had locally advanced disease. In 28.16%, the primary treatment was radiotherapy, in 12.30% it was prostatectomy. A total of 83.48% received hormone treatment. The mean for each scale of the PROSQOLI questionnaire varied from 68.86 to 74.51. The percentage of no response was less than 3% for each scale. The percentage of subjects with minimum score in any scale was negligible, and the maximum score did not surpass 5%. Mean time to fill out the questionnaire was 109.42 (101.00) seconds. Cronbach's ? coefficient was 0.937 and the total item correlation was superior to 0.7 for all the items. Correlations with the EQ-5D questionnaire were moderate. Scores on the questionnaire were associated to all the parameters studied related to the disease. CONCLUSIONS: The adapted questionnaire has adequate psychometric properties for its use in research and in the clinical practice.

Validation of the WHOQOL-BREF quality of life questionnaire for use with medical students.  

UK PubMed Central (United Kingdom)

PURPOSE: The purpose of the present study was to validate the use of the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire with medical students. METHODS: A sample of 274 medical students in their fourth and fifth years of study (80% response rate) completed the WHOQOL-BREF instrument. The four-domain factor structure of the questionnaire was tested using confirmatory factor analysis. A variety of other tests of reliability and validity were conducted. RESULTS: Goodness-of-fit indices from the confirmatory factor analysis were acceptable, and the factor structure of the WHOQOL-BREF was confirmed in this sample. Reliability was good, but three of the items showed strong ceiling effects. CONCLUSION: The WHOQOL-BREF is valid to use with medical students to assess health-related quality of life. Some items, such as those inquiring about pain and medication, may not be suitable for medical students or young people in general.

[Perceptions of dental fluorosis and evaluation of agreement between parents and children: validation of a questionnaire].  

UK PubMed Central (United Kingdom)

This study aimed to validate the Child's and Parent's Questionnaire about Teeth Appearance and to evaluate concerns relative to fluorosis among 213 pairs of parents and 12-year-old children from two regions of Brazil. Reliability was assessed by Cronbach's alpha and intraclass correlation coefficient, and construct and criterion validity by Spearman's correlations. Student t-test was used to compare the two regions and to assess parent/child agreement. Internal consistency was acceptable, and test-retest reliability was moderate to excellent. Perception of moderate to severe fluorosis and clinical data were significantly correlated, as were perception of fluorosis and subjects' concerns. Although parents from Rafael Arruda, Ceará State, showed a higher perception of fluorosis, parental concern was greater in Piracicaba, São Paulo State. Parents were more worried and dissatisfied with their children's dental appearance than the children themselves. This version of the questionnaire proved to be valid and reliable for assessing children's and parents' perceptions of dental fluorosis.

The Effects of Faking on the Construct Validity of Personality Questionnaires: A Direct Faking Measure Approach  

Directory of Open Access Journals (Sweden)

Full Text Available Some authors clearly showed that faking reduces the construct validity of personality questionnaires, whilst many others found no such effect. A possible explanation for mixed results could be searched for in a variety of methodological strategies in forming comparison groups supposed to differ in the level of faking: candidates vs. non-candidates; groups of individuals with "high" vs. "low" social desirability score; and groups given instructions to respond honestly vs. instructions to "fake good". All three strategies may be criticized for addressing the faking problem indirectly – assuming that comparison groups really differ in the level of response distortion, which might not be true. Therefore, in a within-subject design study we examined how faking affects the construct validity of personality inventories using a direct measure of faking. The results suggest that faking reduces the construct validity of personality questionnaires gradually – the effect was stronger in the subsample of participants who distorted their responses to a greater extent.

Doubtful outcome of the validation of the Rome II questionnaire: validation of a symptom based diagnostic tool  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Questionnaires are used in research and clinical practice. For gastrointestinal complaints the Rome II questionnaire is internationally known but not validated. The aim of this study was to validate a printed and a computerized version of Rome II, translated into Swedish. Results from various analyses are reported. Methods Volunteers from a population based colonoscopy study were included (n = 1011), together with patients seeking general practice (n = 45) and patients visiting a gastrointestinal specialists' clinic (n = 67). The questionnaire consists of 38 questions concerning gastrointestinal symptoms and complaints. Diagnoses are made after a special code. Our validation included analyses of the translation, feasibility, predictability, reproducibility and reliability. Kappa values and overall agreement were measured. The factor structures were confirmed using a principal component analysis and Cronbach's alpha was used to test the internal consistency. Results and Discussion Translation and back translation showed good agreement. The questionnaire was easy to understand and use. The reproducibility test showed kappa values of 0.60 for GERS, 0.52 for FD, and 0.47 for IBS. Kappa values and overall agreement for the predictability when the diagnoses by the questionnaire were compared to the diagnoses by the clinician were 0.26 and 90% for GERS, 0.18 and 85% for FD, and 0.49 and 86% for IBS. Corresponding figures for the agreement between the printed and the digital version were 0.50 and 92% for GERS, 0.64 and 95% for FD, and 0.76 and 95% for IBS. Cronbach's alpha coefficient for GERS was 0.75 with a span per item of 0.71 to 0.76. For FD the figures were 0.68 and 0.54 to 0.70 and for IBS 0.61 and 0.56 to 0.66. The Rome II questionnaire has never been thoroughly validated before even if diagnoses made by the Rome criteria have been compared to diagnoses made in clinical practice. Conclusion The accuracy of the Swedish version of the Rome II is of doubtful value for clinical practice and research. The results for reproducibility and reliability were acceptable but the outcome of the predictability test was poor with IBS as an exception. The agreement between the digital and the paper questionnaire was good.

Validação da versão brasileira do Fibromyalgia Impact Questionnaire (FIQ) Validation of the brazilian version of the Fibromyalgia Impact Questionnaire (FIQ)  

Directory of Open Access Journals (Sweden)

Full Text Available OBJETIVO: Desenvolver uma versão transcultural do Fibromyalgia Impact Questionnaire (FIQ) para a população brasileira e analisar sua validade e eficácia quando aplicado em pacientes com fibromialgia. PACIENTES E MÉTODOS: Participaram do estudo 44 pacientes com fibromialgia (FM), diagnosticados segundo os critérios do American College of Rheumatology (ACR), 1990. Baseados nas orientações de Guillemin et al(22), foram convidados quatro professores de língua inglesa, um reumatologista e dois fisioterapeutas. O procedimento seguiu as etapas: tradução inicial por dois professores de inglês, avaliação das duas traduções para uma versão única, versão para a língua inglesa por dois professores de inglês nativos, reunião de consenso com dois professores de inglês, reumatologista e fisioterapeutas para versão teste, avaliação da equivalência cultural, versão final, avaliação da confiabilidade e reprodutibilidade. A versão teste foi aplicada em 20 pacientes com FM, tendo em todas as questões o item "não-aplicável". Substituição de possíveis questões com mais de 15% de respostas "não-aplicável" por outras de mesmo conceito, resultando na versão final. Aplicação dessa versão em 24 pacientes com FM por dois avaliadores que fizeram a entrevista no mesmo dia com intervalo de uma hora e, após um período de sete dias da primeira avaliação, o questionário foi reaplicado pelo primeiro avaliador. RESULTADOS: Na aplicação da versão teste não houve questões com mais de 15% de respostas "não-aplicável". Sendo assim, não foi mudado o texto para a versão final. Porém, houve dificuldade de compreensão das escalas visuais analógicas (questões 4 a 10). Com isso, foram acrescidas "carinhas" nos dois extremos: à esquerda uma "carinha" feliz e à direita, uma infeliz. Esse processo deu origem à versão final. Na avaliação da confiabilidade, os resultados do avaliador 1 (primeira e segunda aplicação) e do avaliador 2 foram comparados, bem como as duas aplicações do avaliador 1. Ambas demonstraram que não houve diferença entre os dois avaliadores no que diz respeito a aplicação do questionário. A comparação entre os avaliadores foi feita com base nas médias globais. Os valores de p foram todos superiores a 10%, indicando que não houve evidência de diferenças significantes entre aplicações dos questionários nos mesmos pacientes.

PATIENTS AND METHODS: Forty-four fibromyalgia patients classified following the 1990 American College Rheumatology (ACR) criteria. According to the 1993 Guillemin et al(22) guidelines, four English teachers, one rheumatologist and two physical therapist were invited to participate. The procedure was established according to the following steps: initial translation by two English teachers, evaluation of these two translations to a unique version, back translation to English by two native teachers, a consensus meeting where there were two English teachers, one rheumatologist and physiotherapists for the test-translation, evaluation of cultural equivalency, final version, reliability and reproducibility. The test-translation has been applied to 20 fibromyalgia patients, having in all questions the item "not applicable". Questions answered as "not applicable" by 15% or more patients were reformulated, resulting in the final version. Application of the final version to 24 fibromyalgia patients by two different interviewers who applied the final questionnaire in the same day, with one hour interval and seven days after the first interview, the questionnaire was re-applied by the first interviewer. RESULTS: During the application of the test-version none

Validity and Reliability of the Malay Version of WHO Women's Health and Life Experiences Questionnaire.  

Science.gov (United States)

The Women's Health and Life Experiences questionnaire measures the prevalence, health implications, and risk factors for domestic violence. This cross-sectional study was conducted to determine the validity and reliability of the Malay version of World Health Organization (WHO) Women's Health and Life Experiences Questionnaire. Construct validity and reliability assessment of the Malay version of the questionnaire was done on 20 specific items that measure four types of intimate partner violence (IPV) act; controlling behaviors (CB), emotional violence (EV), physical violence (PV), and sexual violence (SV), which were considered as the domains of interest. Face-to-face interviewing method was used for data collection. A total of 922 women completed the interviews. The results showed that exploratory factor analysis of four factors with eigenvalues above 1 accounted for 63.83% of the variance. Exploratory factor analysis revealed that all items loaded above 0.40 and the majority of items loaded on factors that were generally consistent with the proposed construct. The internal consistency reliability was good. The Cronbach's ? values ranged from 0.767 to 0.858 across domains. The Malay version of WHO Women's Health and Life Experiences Questionnaire is a valid and reliable measure of women's health and experiences of IPV in Malaysia. PMID:23508088

The validation of a food label literacy questionnaire for elementary school children.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To determine the reliability and validity of a 10-item questionnaire, the Food Label Literacy for Applied Nutrition Knowledge questionnaire. METHODS: Participants were elementary school children exposed to a 90-minute school-based nutrition program. Reliability was assessed via Cronbach ? and intraclass correlation coefficient (ICC). Validity was assessed comparing the questionnaire's food choices using an objective metric of nutrition quality, the Overall Nutritional Quality Index (ONQI), via t test. Statistical significance was set at .05. RESULTS: Four hundred ninety-nine children participated, 51% were female, and the average age was 8.6 (± 0.9) years. Cronbach ? = .77 and ICC = 0.68 (between administrations) were observed. ONQI scores of correct responses were significantly higher when compared to the ONQI scores of incorrect responses (27.4 ± 9.4 vs 16.2 ± 9.4; P = .01). CONCLUSIONS AND IMPLICATIONS: The Food Label Literacy for Applied Nutrition Knowledge questionnaire was found to be both reliable and a valid measure of food label literacy in children taught the Nutrition Detectives program.

Validation of the historical adulthood physical activity questionnaire (HAPAQ) against objective measurements of physical activity  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Lifetime physical activity energy expenditure (PAEE) is an important determinant of risk for many chronic diseases but remains challenging to measure. Previously reported historical physical activity (PA) questionnaires appear to be reliable, but their validity is less well established. Methods We sought to design and validate an historical adulthood PA questionnaire (HAPAQ) against objective PA measurements from the same individuals. We recruited from a population-based cohort in Cambridgeshire, UK, (Medical Research Council Ely Study) in whom PA measurements, using individually calibrated heart rate monitoring, had been obtained in the past, once between 1994 and 1996 and once between 2000 and 2002. 100 individuals from this cohort attended for interview. Historical PA within the domains of home, work, transport, sport and exercise was recalled using the questionnaire by asking closed questions repeated for several discrete time periods from the age of 20 years old to their current age. The average PAEE from the 2 periods of objective measurements was compared to the self-reported data from the corresponding time periods in the questionnaire. Results Significant correlations were observed between HAPAQ-derived and objectively measured total PAEE for both time periods (Spearman r = 0.44; P Conclusions HAPAQ demonstrates convergent validity for total PAEE and vigorous PA. This instrument will be useful for ranking individuals according to their past PA in studies of chronic disease aetiology, where activity may be an important underlying factor contributing to disease pathogenesis.

[Validation of a questionnaire on improving work satisfaction (CMSL) in primary care professionals].  

UK PubMed Central (United Kingdom)

BACKGROUND: Job satisfaction of health professionals is considered to be a quality indicator, as it is related to the efficacy of the services. The aim of the study is to validate a questionnaire for evaluating job satisfaction improvement in a population of health professionals in primary care in Navarre. METHODOLOGY: Descriptive study with self-completed questionnaires; the target population was all health care professionals (family doctors, pediatricians and nurses) of primary health centers of Navarre. A Lickert scale was used for measuring the items. Other variables measured were: sex, years in the profession, job satisfaction, professional status, health center, and 47 items on improving job satisfaction. Cronbach's alpha coefficient was used to evaluate reliability, and to evaluate construct validity factor analysis with varimax rotation, grouping the items in 9 dimensions was used. RESULTS: A total of 414 questionnaires were collected. Cronbach's alpha coefficient was 0.933. Forty-one point two eight seven percent (41.287%) of total variance was explained by five dimensions. The dimension "relations with patients" presented the highest average (4.087) of improvement in job satisfaction, and the item "If it were possible to eliminate unjustified demand" showed an average of 4.21. CONCLUSIONS: The questionnaire designed is a valid instrument for a comprehensive evaluation of the improvement in the job satisfaction of primary care professionals. The results obtained can indicate which areas of improvement should be implemented in order to improve the satisfaction of the professionals.

Development and validation of an asthma knowledge questionnaire for use in Brazil.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To develop and validate an asthma knowledge questionnaire for use in adult asthma patients in Brazil. METHODS: A 34-item self-report questionnaire was constructed and administered to adult asthma patients and adult controls. The maximum total score was 34. RESULTS: The questionnaire was shown to be discriminatory, with good reliability and reproducibility. The mean score for asthma patients and controls was, respectively, 21.47 +/- 4.11 (range: 9-31) and 17.27 +/- 5.11 (range: 7-28; p < 0.001). The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.53, and the Bartlett's test of sphericity demonstrated a satisfactory suitability of the data to factor analysis (p < 0.001). There was no significant difference between the total scores obtained in the first and in the second application of the questionnaire within a two-week interval (p = 0.43). The internal consistency reliability (KR-20 coefficient) was 0.69. CONCLUSIONS: This study has validated an asthma knowledge questionnaire for use in Brazil.

The validity of a questionnaire-based epidemiological study of occupational dermatosis.  

UK PubMed Central (United Kingdom)

The aim of this study was to evaluate the validity of a questionnaire and medical anamnesis to identify persons with dermatitis in an occupational setting. The design was a clinical epidemiological cross-sectional study. The study was performed between the second and fourth week of January 2001. A questionnaire was followed a week later by a medical occupational interview and a clinical dermatological examination, including a comprehensive patch test with potential workplace chemicals. The anamnesis and the clinical examination were made independently by occupational and dermatological physicians, and the skin examination was performed blinded to anamnestic data. The setting was the mother plants of a Danish-based international company producing wind turbine systems. The study population was a workplace cohort, highly exposed to epoxy resin systems and other chemicals, and totalled 724 production workers at 4 facilities. The rate of participation was 84.7%. Using enquete questions of current skin rash against the clinical presence of dermatitis, we found a sensitivity of 22% and a specificity of 89%, compared to 45% and 87%, respectively, when the anamnestic work history, taken by an occupational physician, was the screening parameter. Using 'workplace periodic prevalence' of dermatitis, we found sensitivities in the range of 63-76% by a questionnaire and 70-83% by medical anamnesis. Questionnaire screening by skin symptoms gave the highest values for redness, a sensitivity of 33% and a specificity of 76%, and decreasing validity parameters as more symptoms were added to the list of screening questions. We found that the use of a questionnaire and medical anamnesis were problematic, when the purpose was screening for contact dermatitis and allergy, in this industrial cohort manufacturing reinforced plastic products. But these instruments might be useful for epidemiological surveillance, when the questionnaire has been validated in the given occupational setting.

UK PubMed Central (United Kingdom)

BACKGROUND: ConQoL questionnaire assesses health related quality of life among children with congenital heart diseases. It has a version for children aged 8 to 11 years and another for children aged 12 to 16 years. AIM: To validate ConQol questionnaire for Chilean children with a congenital heart disease. MATERIAL AND METHODS: Using a multicentric cross sectional design, 334 children from four hospitals (54% males), were surveyed. Among them 45% were aged 8 to 11 years and 55%, 12 to 16 years. The study involved three stages: cross cultural adjustment of the original questionnaire, pre-test study, and estimation of its psychometric properties. Content, construct and criterion validity and internal consistency with Cronbach's alpha, were assessed. RESULTS: The version for children aged 8 to 11 years and comprised by three domains (symptoms, activity and relationships), obtained and ? ? 0.60. In the questionnaire for children aged 12 to 16 years, there is one more domain called coping, which obtained an ? of 0.53, that was different to the other three domains that obtained an ? > 0.70. The correlation between Health Quality of Life and Perception of Health Quality of Life was statistically significant for both groups. The association between Health Quality of Life and health capability was only significant among children aged 12 to 16 years (p < 0.01). CONCLUSIONS: The adapted ConQol questionnaire matched properly with the original one. The adapted questionnaire is valid and reliable to assess Health Quality of Life among Chilean children with congenital heart diseases.

Spanish translation and validation of four short pelvic floor disorders questionnaires.  

UK PubMed Central (United Kingdom)

INTRODUCTION AND HYPOTHESIS: Globally, Spanish is the primary language for 329 million people; however, most urogynecologic questionnaires are available in English. We set out to develop valid Spanish translations of the Questionnaire for Urinary Incontinence Diagnosis (QUID), the Three Incontinence Questions (3IQ), and the short Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7). METHODS: The TRAPD method (translation, review, adjudication, pretesting, and documentation) was used for translation. Eight native Spanish-speaking translators developed Spanish versions collaboratively. These were pretested with cognitive interviews and revised until optimal. For validation, bilingual patients at seven clinics completed Spanish and English questionnaire versions in randomized order. Participants completed a second set of questionnaires later. The Spanish versions' internal consistency and reliability and Spanish-English agreement were measured using Cronbach's alpha, weighted kappa, and intraclass correlation coefficients. RESULTS: A total of 78 subjects were included; 94.9 % self-identified as Hispanic and 73.1 % spoke Spanish as their primary language. The proportion of per-item missing responses was similar in both languages (median 1.3 %). Internal consistency for Spanish PFDI-20 subscales was acceptable to good and for PFIQ-7 and QUID excellent. Test-retest reliability per item was moderate to near perfect for PFDI-20, substantial to near perfect for PFIQ-7 and 3IQ, and substantial for QUID. Spanish-English agreement for individual items was substantial to near perfect for all questionnaires (kappa range 0.64-0.95) and agreement for PFDI-20, PFIQ-7, and QUID subscales scores was high [intraclass correlation coefficient (ICC) range 0.92-0.99]. CONCLUSIONS: We obtained valid Spanish translations of the PFDI-20, PFIQ-7, QUID, and 3IQ. These results support their use as clinical and research assessment tools in Spanish-speaking populations.

AB 7. Validation of the greek version of the severe respiratory insufficiency questionnaire  

Science.gov (United States)

Background The Severe Respiratory Insufficiency (SRI) questionnaire is a multidimensional tool, which has been validated for the assessment of health-related quality of life (HRQL) in patients with severe chronic respiratory failure resulting from a variety of underlying disorders. Aim of this study was the validation of the SRI questionnaire in a sample of Greek patients with severe chronic respiratory failure. Patients and methods The SRI questionnaire contains seven subscales related to respiratory complaints (RC), physical functioning (PF), attendant symptoms and sleep (AS), social relationships (SR), anxiety (AX), psychological well-being (WB), social functioning (SF) and a summary scale (SS). We studied 136 consecutive patients with severe respiratory failure of miscellaneous origin. Sixty-three patients (46.3%) were on Long-Term Oxygen Therapy (LTOT) while 73 (53.7%) received Home Mechanical Ventilation (HMV) in addition to LTOT. All patients underwent lung function testing and completed the SRI questionnaire. Results The Cronbach’s A was high for the summary scale with a value 0.856 showing high internal consistency. The results of the principal component analysis (PCA) on the SRI-SS produce a one factor construct with a variance of 54%, which validates the preexisting one factor SS. HMV group patients had higher SRI-SS score than LTOT group (61.5 vs. 60.5, P=NS). The highest and the lowest score were detected in SRI-RC and SRI-PF subscales in both groups. COPD patients had lower SRI-SS score than non-COPD. Regarding COPD subgroups, the SRI-SS score was 52.9 in COPD-HMV patients and 60.3 in COPD-LTOT (P=NS). Conclusions The Greek version of the SRI questionnaire is equivalent to the original one and well-reproducible in patients with severe chronic respiratory failure. This questionnaire could be used in Greek-speaking people in the same way as in other languages to assess HRQL.

Family physicians' diagnostic gut feelings are measurable: construct validation of a questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: Family physicians perceive that gut feelings, i.e. a 'sense of reassurance' or a 'sense of alarm', play a substantial role in diagnostic reasoning. A measuring instrument is desirable for further research. Our objective is to validate a questionnaire measuring the presence of gut feelings in diagnostic reasoning. METHODS: We constructed 16 case vignettes from real practice situations and used the accompanying 'sense of reassurance' or the 'sense of alarm' as reference labels. Based on the results of an initial study (26 family physicians), we divided the case vignettes into a group involving a clear role for the sense of reassurance or the sense of alarm and a group involving an ambiguous role. 49 experienced family physicians evaluated each 10 vignettes using the questionnaire. Construct validity was assessed by testing hypotheses and an internal consistency procedure was performed. RESULTS: As hypothesized we found that the correlations between the reference labels and corresponding items were high for the clear-case vignettes (0.59 - 0.72) and low for the ambiguous-case vignettes (0.08 - 0.23). The agreement between the classification in clear sense of reassurance, clear sense of alarm and ambiguous case vignettes as derived from the initial study and the study population's judgments was substantial (Kappa = 0.62). Factor analysis showed one factor with opposites for sense of reassurance and sense of alarm items. The questionnaire's internal consistency was high (0.91). We provided a linguistic validated English-language text of the questionnaire. CONCLUSIONS: The questionnaire appears to be valid. It enables quantitative research into the role of gut feelings and their diagnostic value in family physicians' diagnostic reasoning.

Validation of the Spanish version of the "Questionnaire on the treatment of approximal and occlusal caries".  

UK PubMed Central (United Kingdom)

OBJECTIVES: To translate and validate a Spanish version of the "Questionnaire on the treatment of approximal and occlusal caries" as a method of collecting information about treatment decisions on caries management in Chilean primary health care services. MATERIALS AND METHODS: The original questionnaire proposed by Espelid et al. was translated into Spanish using the forward-backward translation technique. Subsequently, validation of the Spanish version was undertaken. Data were collected from two separate samples; first, from 132 Spanish-speaking dentists recruited from primary health care services and second, from 21 individuals characterised as cariologists. Internal consistency was evaluated by the generation of Cronbach's alpha, test-retest reliability was evaluated by Cohen's kappa, convergent validity was evaluated by comparing the total scale scores to a global evaluation of treatment trends and discriminant validity was evaluated by investigating the differences in total scale scores between the Spanish-speaking dentist and cariologist samples. RESULTS: Cronbach's alpha indicated an internal consistency of 0.63 for the entire scale. Cohen's kappa correlation coefficient expressed a test-retest reliability of 0.83. Convergent validity determined a Pearson's correlation coefficient of 0.24 (p?validity was statistically significant (p?Questionnaire on the treatment of approximal and occlusal caries" is a valid and reliable instrument for collecting information regarding treatment decisions in cariology. CLINICAL RELEVANCE: The clinical relevance of this study is to acquire a reliable instrument that allows for the determination of treatment decisions in Spanish-speaking dentists.

Validation of a migraine screening questionnaire in a Colombian university population.  

UK PubMed Central (United Kingdom)

In studies of migraine prevalence, it is important to be aware of the discriminative capacity of the test used. We set out to validate a Spanish translation of Michel's Standardized Migraine Diagnosis Questionnaire. The questionnaire was applied on all active students of the School of Psychology of the Universidad Autónoma de Bucaramanga, Colombia. A neurologist interviewed a random sample to substantiate the diagnosis of migraine. Cronbach's alpha was calculated and factors analysis was made in order to estimate internal consistency, test-retest to find reproducibility, and ROC curve and diagnostic indicators were calculated to estimate the criteria validity. Of 357 students that answered the questionnaire, 188 (52.7%) were selected at random to attend an appointment with a neurologist, but only 170 had this interview. Cronbach's alpha on these 357 questionnaires is 0.7497. All the questions on the questionnaire represented two main factors. This test had sensitivity in 37.9% [95% confidence interval (CI) 25.8, 51.7], specificity in 99.1% (95% CI 94.4, 100), positive predictive value in 95.7% (95% CI 76.0, 99.8), and negative predictive value in 75.5% (95% CI 67.6, 82.1) for 17 or more points. The area below ROC curve is 0.8529 (95% CI 0.8035, 0.9217). Among 84 students who took the questionnaire a second time, the average score on the first survey was 12.33 +/- 7.46 points, while the average score on the second take was 11.26 +/- 7.85 (P = 0.069). Agreement for migraine is 83.3% (95% CI 73.6, 90.6; Cohen's kappa = 0.6650 +/- 0.1061). The Spanish translation of Michel's Questionnaire is easy to answer and has good internal consistency, but its reproducibility and sensibility are modest; however, the ROC curve is acceptable to discriminate migraine patients from normal subjects.

Validation of the LittlEARS((R)) Auditory Questionnaire in children with normal hearing.  

UK PubMed Central (United Kingdom)

OBJECTIVES: With more children receiving cochlear implants during infancy, there is a need for validated assessments of pre-verbal and early verbal auditory skills. The LittlEARS Auditory Questionnaire is presented here as the first module of the LittlEARS test battery. The LittlEARS Auditory Questionnaire was developed and piloted to assess the auditory behaviour of normal hearing children and hearing impaired children who receive a cochlear implant or hearing aid prior to 24 months of age. This paper presents results from two studies: one validating the LittlEARS Auditory Questionnaire on children with normal hearing who are German speaking and a second validating the norm curves found after adaptation and administration of the questionnaire to children with normal hearing in 15 different languages. METHODS: Scores from a group of 218 German and Austrian children with normal hearing between 5 days and 24 months of age were used to create a norm curve. The questionnaire was adapted from the German original into English and then 15 other languages to date. Regression curves were found based on parental responses from 3309 normal hearing infants and toddlers. Curves for each language were compared to the original German validation curve. RESULTS: The results of the first study were a norm curve which reflects the age-dependence of auditory behaviour, reliability and homogeneity as a measure of auditory behaviour, and calculations of expected and critical values as a function of age. Results of the second study show that the regression curves found for all the adapted languages are essentially equal to the German norm curve, as no statistically significant differences were found. CONCLUSIONS: The LittlEARS Auditory Questionnaire is a valid, language-independent tool for assessing the early auditory behaviour of infants and toddlers with normal hearing. The results of this study suggest that the LittlEARS Auditory Questionnaire could also be very useful for documenting children's progress with their current amplification, providing evidence of the need for implantation, or highlighting the need for follow-up in other developmental areas.

Validation of a maternal questionnaire on correlates of physical activity in preschool children  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Valid measures of physical activity correlates in preschool children are lacking. This study aimed to assess the validity, factor structure and internal consistency of a maternal questionnaire on potential correlates of four-year-old children's physical activity. Methods The questionnaire was designed to measure the following constructs: child personal factors; parental support and self-efficacy for providing support; parental rules and restrictions; maternal attitudes and perceptions; maternal behaviour; barriers to physical activity; and the home and local environments. Two separate studies were conducted. Study I included 24 mothers of four-year-old children who completed the questionnaire then participated in a telephone interview covering similar items to the questionnaire. To assess validity, the agreement between interview and questionnaire responses was assessed using Cohen's kappa and percentage agreement. Study II involved 398 mothers of four-year-old children participating in the Southampton Women's Survey. In this study, principal components analysis was used to explore the factor structure of the questionnaire to aid future analyses with these data. The internal consistency of the factors identified was assessed using Cronbach's alpha. Results Kappa scores showed 30% of items to have moderate agreement or above, 23% to have fair agreement and 47% to have slight or poor agreement. However, 89% of items had fair agreement as assessed by percentage agreement (? 66%). Limited variation in responses to variables is likely to have contributed to some of the low kappa values. Six questions had a low kappa and low percentage agreement (defined as poor validity); these included questions from the child personal factors, maternal self-efficacy, rules and restrictions, and local environment domains. The principal components analysis identified eleven factors and found several variables to stand alone. Eight of the composite factors identified had acceptable internal consistency (? ? 0.60) and three fell just short of achieving this (0.60 > ? > 0.50). Conclusion Overall, this maternal questionnaire had reasonable validity and internal consistency for assessing potential correlates of physical activity in young children. With minor revision, this could be a useful tool for future research in this area. This, in turn, will aid the development of interventions to promote physical activity in this age group.

Validation of Noise Induced Hearing Loss Questionnaire Among Malay Sawmill Workers in Kelantan Malaysia  

Directory of Open Access Journals (Sweden)

Full Text Available Exposure to excessive noise is the major avoidable cause of permanent hearing impairment. Sawmill is one of the workplaces where workers are exposed to hazardous noise level. This study was conducted to determine the reliability and validity of noise-induced hearing loss questionnaire among sawmill workers. Materials and Methods: This cross sectional study was conducted in March 2007 among 35 consented sawmill workers. A total of 40 items; 10 items for knowledge (8 areas), 20 items for attitude (7 areas) and 10 items for practice (2 areas) were assessed. Statistical analysis for reliability analysis was test by internal consistency and construct validity by exploratory factor analysis using principal components and Varimaxrotation method. Results: Cronbach’s alpha coefficients were acceptable for attitude (0.90) and practice (0.75). However, it was low for knowledge (0.67). Exploratory factor analysis showed three meaningful exploratory factors that could explain the three dimensions in the questionnaire. Conclusion: The results of the validation study suggested that the noise-induced hearing loss questionnaire is reliable and valid tool for assessing knowledge, attitude and practice among sawmill workers.

Content validity of the Dutch version of the Neck Bournemouth Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: Mechanical neck pain is a common human phenomenon. In most cases, no patho-anatomical lesion can be identified with the limitations of current radiological imaging. Therefore it is preferable to assess patients with neck pain with a focus on functioning and health, within a biopsychosocial model. The Neck Bournemouth Questionnaire aims to assess biopsychosocial aspects of neck pain. However, the content validity of the Neck Bournemouth Questionnaire Dutch language version (NBQ-NL) in relation to the International Classification of Functioning, Disability and Health (ICF) is unknown. The purpose of the study was to examine the content validity of the NBQ-NL in relation to the health components of the ICF. METHOD: Content validity was assessed in relation to the ICF, by means of Discriminant Content Validity (DCV). RESULTS: The results indicate that the NBQ-NL measures four components of the five ICF (impairment, activity, participation and personal factors). CONCLUSION: The NBQ is a multidimensional questionnaire, representing four of the five components of the ICF.

[Validation of the MALT-S questionnaire for the diagnosis of alcoholism among the adult population].  

UK PubMed Central (United Kingdom)

OBJECTIVE: To validate the subjective part of the MALT questionnaire (MALT-S) for the detection of alcoholism among the adult population. DESIGN: A descriptive study on the validation of a diagnostic tool. SETTING: Two primary health care centres, a centre for drug addicts and a centre for alcoholics in Cordoba (Spain). PARTICIPANTS: 614 patients, between 18 and 80 years. MEASUREMENTS: Through personal interviews the MALT, AUDIT and SCAN questionnaires were given. The internal reliability, stability and both the criterion and convergent validity were analysed. RESULTS: The mean age of the population' was 43+/-1.43 (SD) years and 17.4% of them showed Alcohol Dependence Syndrome. The Kappa coefficients of the test items ranged from 0.568 to 0.969. The Cronbach alpha of the complete MALT was 0.919, of the MALT-S, 0.939 and of the MALT-O, 0.737. The area under the ROC curve of the MALT-S was 0.946 and that of the complete MALT was 0.953. For a cut-off point of four, the sensitivity of the MALT-S is 92.7% while its specificity was 90.9%. The correlation coefficient of the MALT-S and AUDIT was 0.86 (P<0.001). CONCLUSIONS: The MALT-S questionnaire is as valid and reliable as the complete MALT; therefore, it can be used on its own for the diagnosis of alcoholism.

Development and validation of the Burdens in Oral Surgery Questionnaire (BiOS-Q).  

Science.gov (United States)

Patients' perspective is increasingly re-cognised as an important outcome measure in oral surgery. However, how patients perceive the surgical treatment cannot be assessed currently. This would be an important indicator for process-related quality of care. It was the aim to develop and to validate an instrument for the assessment of patient-based measures of process-related quality of care in oral surgery. The new Burdens in Oral Surgery Questionnaire (BiOS-Q) was developed in two steps in patients undergoing oral surgery. First, an item pool was created using semi-structured interviews in 90 patients. Second, a preliminary version was applied in 297 consecutively recruited patients to assess redundancy, completion rates, face validity, difficulty and distribution. Psychometric properties of the final version of the questionnaire were evaluated. The BiOS-Q consists of 16 items and showed satisfactory internal consistency (Cronbach's alpha = 0·84) and excellent test-retest reliability (ICC = 0·90). The questionnaire's mean score was significantly correlated with dentists' burdens (r = 0·44) and patients' overall satisfaction (r = 0·39) indicating sufficient validity. The BiOS-Q is a reliable and valid instrument for the assessment of patient-based process-related quality of care in oral surgery. PMID:24033878

A Brazilian Portuguese version of the Revised Fibromyalgia Impact Questionnaire (FIQR): a validation study.  

Science.gov (United States)

The Fibromyalgia Impact Questionnaire (FIQ) was specifically developed to assess disease severity and functional ability in fibromyalgia patients. In 2009, a revised version of the FIQ was published, the FIQR; this version achieved a better balance among different domains (function, overall impact, symptoms). Here, we present the validity and reliability of the Brazilian version of the Revised Fibromyalgia Impact Questionnaire (FIQR). Female fibromyalgia patients (n?=?106) completed an online survey consisting of the Short Form 36 (SF-36) questionnaire, the original FIQ, and the Brazilian Portuguese FIQR, which was translated by a standard method. Validity was established with correlational analyses between the FIQR, FIQ, and SF-36 items. Three domains were established for the FIQR (function, overall impact, symptoms), and their contribution for the SF-36 subscales was also scrutinized. The Brazilian FIQR validation process showed that the questions performed in a very similar way to the original English FIQR. The new questions in the FIQR symptoms domain (memory, balance, tenderness, and environmental sensitivity) revealed a significant impact in fibromyalgia (FM) patients. The Brazilian Portuguese FIQR demonstrated excellent reliability, with a Cronbach's alpha of 0.96. There was a gain on weight of the function domain and a decrease of the symptom domain, leading to a better balance among domains. The FIQR predicted a great number of SF-36 subscales, showing good convergent validity. The Brazilian Portuguese version of the FIQR was validated and found to be a reliable, easy-to-use, and score FM-specific questionnaire that should prove useful in routine clinical practice and FM-related research.

Validity and reliability of the Persian version of the multiple sclerosis quality of life questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Aims: To translate and test the reliability and validity of the Multiple Sclerosis Quality of Life Questionnaire (MSQoL-54) in Iranian MS patients. Setting and Design: Using a standard "forward-backward" translation, cognitive debriefing and cultural adaptation procedure, the English version of the MSQoL-54 was translated to Persian which is the Iranian official language. Materials and Methods: The subjects were multiple sclerosis (MS) patients referred to Motaharri clinic, Shiraz, South of Iran. Demographic data were recorded. Epidemiological data concerning MS type, duration of the disease, Functional System Score (FSS) and Expanded Disability Status Scale (EDSS) of patients were also provided by a qualified neurologist. Statistical Analysis: The reliability of the questionnaire was assessed by Cronbach?s alpha coefficient. Construct validity was assessed through factor analysis. Factor analysis was performed to determine that the Persian version is a two-dimensional measure including physical and mental parameters. Results: Multiple sclerosis patients (female:106 (75.2%), male:35 (24.8%)), with a mean±SD age of 32.2±9.8 years were enrolled in the study. Cronbach?s ? was 0.962. There were no significant differences between each item and the mean of physical and mental scores of MSQoL-54, regarding sex, marital status and education. There was a negative significant correlation between EDSS and physical health, role limitation due to physical problems, pain, energy, health perception, social function, cognitive function, health distress, overall Quality of Life. The scaling success rates were 100%, demonstrating convergent validity of each scale. Factor analysis confirmed the construct validity of the questionnaire. Conclusions: The Persian version of the MSQoL-54 questionnaire has a good structural characteristic, it is a reliable and valid instrument and can be used for measuring the effect of MS on the Quality of Life.

The validity and precision of the Leicester Cough Questionnaire in COPD patients with chronic cough.  

UK PubMed Central (United Kingdom)

BACKGROUND: A validated instrument to assess the effects of chronic cough on health status in patients with chronic obstructive pulmonary disease (COPD) is currently not available. The Leicester Cough Questionnaire (LCQ) is a cough-specific health status questionnaire which is originally validated for a population of general patients presenting with chronic cough. We examined the psychometric performance of the LCQ in patients with COPD and chronic productive cough. METHODS: Concurrent validity, internal consistency, reproducibility and responsiveness were determined. The St. George's Respiratory Questionnaire (SGRQ) and the Short Form-36 (SF-36) were used as external criteria. Questionnaires were completed at the start of the study. After 2 and 12 weeks the LCQ was repeated, together with a global rating of change. RESULTS: In total 54 patients were included. Concurrent validity analysis showed significant correlations between corresponding domains of the LCQ and the SGRQ (r(s) -0.31 to -0.60). Corresponding domains of the LCQ and the SF-36 showed weaker correlations (r(s) 0.04 to 0.41). Internal consistency was adequate for two of the three domains (Cronbach's ? 0.74 - 0.86). Test-retest reliability in stable patients was high (intraclass correlation coefficients 0.79 - 0.93). The mean difference after two weeks was 0.73 (± 1.75). Responsiveness analysis indicated that the LCQ was able to detect changes after 12 weeks. CONCLUSION: The LCQ is a valid, reliable, responsive instrument to measure health status in COPD patients with chronic productive cough. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01071161.

The effort-reward imbalance questionnaire in Greek: translation, validation and psychometric properties in health professionals.  

UK PubMed Central (United Kingdom)

OBJECTIVES: The aim of the present study was to translate, adapt and validate the Effort-reward imbalance (ERI) questionnaire in a sample of Greek healthcare professionals. METHODS: An internationally recommended methodology was followed to perform translation of the ERI instrument into the Greek language. The questionnaire was then randomly administered to 600 Greek physicians, nurses, physiotherapists and laboratory staff, and 456 questionnaires with no missing data on the ERI items were returned (76% response rate). Tool validation included assessment of internal consistency, factorial structure, discriminant validity and presence of floor or ceiling effects. Criterion validity was demonstrated by investigating the association of theoretically relevant ERI summary measurements with respondents' self-rated health. RESULTS: The Greek version of the ERI questionnaire showed good psychometric properties. Cronbach's alpha values were 0.79, 0.72 and 0.75 for the three ERI scales of effort, reward and overcommitment respectively. Exploratory factor analysis yielded a 5-factor solution that closely reflected the original theoretical ERI model. Significant associations were found between respondents' age, gender and specific occupation with ERI scores. ERI ratio and "overcommitment" scores in the highest tertiles were associated with elevated odds ratios (OR) of below-average self-rated health (OR=5.38, 95% confidence intervals 1.77 to 16.38, p=0.003, and OR=3.41, 95% confidence intervals 1.39 to 8.38, p=0.007, respectively). CONCLUSIONS: The translated and adapted Greek version is comparable with the original ERI instrument in terms of validity and factorial structure and is suitable for assessment of the psychosocial work environment of Greek healthcare professionals.

Validity and reliability of a physical activity questionnaire for Vietnamese adolescents  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Accurate assessment of physical activity in adolescents at population level is necessary. In Vietnam, the International Physical Activity Questionnaire (IPAQ) and Physical Activity Questionnaire for Adolescents (PAQA) have been validated against accelerometers for use in adolescents. However, these questionnaires were originally designed for adults and showed poor validity. This study aims to assess the reliability and validity of the Vietnamese Adolescent Physical Activity Recall Questionnaire (V-APARQ). Methods One hundred and sixty five students were recruited from four junior high schools in Ho Chi Minh City Vietnam in 2004. V-APARQ asked students to report their usual organised and non-organised physical activity during a normal week and moderate- (MPA), vigorous- (VPA and moderate-to-vigorous- (MVPA) physical activity were calculated. Reliability was assessed by test-retest (2?weeks apart). Construct validity was assess by 7-day accelerometry, following the completion of the first V-APARQ. Results The construct validity of the V-APARQ showed Spearman correlation of 0.25 and 0.22 for the assessment of the questionnaire when compared to the accelerometer. Test-retest reliability showed a weighted Kappa of 0.75 and the intra-class correlation coefficient for MVPA was 0.57 for the whole group (MPA =0.37 and VPA?=?0.62), and were higher in boys than girls. The Bland-Altman plots for reliability show a mean difference of 0.4 minutes (95?% CI?=??3.2, 4.0) for daily MVPA (n?=?146) and the limits of agreement were ?42.6 to 43.4 mins/day. In boys MVPA was lower on the first, compared with second administration of V-APARQ while the reverse was observed among girls. Conclusion The reliability and validity of the V-APARQ were low to fair, but are comparable to other self-report physical activity questionnaires used among adolescents. V-APARQ will be useful for population monitoring of change in physical activity among urban Vietnamese adolescents.

Validity and reliability of an occupational exposure questionnaire for parkinsonism in welders.  

Science.gov (United States)

This study assessed the validity and test-retest reliability of a medical and occupational history questionnaire for workers performing welding in the shipyard industry. This self-report questionnaire was developed for an epidemiologic study of the risk of parkinsonism in welders. Validity participants recruited from three similar shipyards were asked to give consent for access to personnel files and complete the questionnaire. Responses on the questionnaire were compared with information extracted from personnel records. Reliability participants were recruited from the same shipyards and were asked to complete the questionnaire at two different times approximately 4 weeks apart. Percent agreement, kappa, intraclass correlation coefficient (ICC), and sensitivity and specificity were used as measures of validity and/or reliability. Personnel files were obtained for 101 of 143 participants (70%) in the validity study, and 56 of the 95 (58.9%) participants in the reliability study completed the retest of the questionnaire. Validity scores for items extracted from personnel files were high. Percent agreement for employment dates and job titles ranged from 83-100%, while ICC for start and stop dates ranged from 0.93-0.99. Sensitivity and specificity for current job title ranged from 0.5-1.0. Reliability scores for demographic, medical and health behavior items were mainly moderate or high, but ranged from 0.19 to 1.0. Most recent job/title items such as title, types of welding performed, and material used showed substantial to perfect agreement. Certain determinants of exposure such as days and hours per week exposed to welding fumes demonstrated mainly moderate agreement (kappa= 0.42-0.47, percent agreement 63-77%); however, mean days and hours reported did not differ between test and retest. The results of this study suggest that participants' self-report for job title and dates employed are valid compared with employer records. While kappa scores were low for some medical conditions and for caffeine consumption, high kappa scores for job title, dates worked, types of welding, and materials welded suggest participants generated reproducible answers important for occupational exposure assessment.

A Questionnaire for Motivation towards Science Learning: A Validity and Reliability Study  

Directory of Open Access Journals (Sweden)

Full Text Available Motivation is one of the main factors in education. It is a dimension that should not be neglected in classes, hard to be comprehended by students, like Science and Mathematics. Thus, the purpose of this study was to develop a Likert-type questionnaire to measure students’ motivation towards Science learning. In order to develop this questionnaire, a pretest form was developed through a literature survey, and presented to experts for their evaluation. After the alterations based on their suggestions, a pilot study with 183 middle school students was held to revise the questionnaire. After the revision, a total of 39 items in the questionnaire was administered to the sample group of 421 elementary school students. By this way, a questionnaire consisting of 23 items were developed. In order to obtain validity, exploratory factor analysis was performed. The results of factor analysis indicated that there are five factors explaining 47% of the total variance in the questionnaire. Moreover, the reliability coefficient (Cronbach Alpha) was found to be .80.

[Validity of a questionnaire for the assessment of work-related musculoskeletal symptoms and physical demands].  

UK PubMed Central (United Kingdom)

BACKGROUND: Participatory ergonomics interventions are frequently based on the use of self-answered questionnaires intended to gathering information on work-related musculoskeletal symptoms and physical demands reported by workers. The aim of this study is to assess the validity of a questionnaire designed to be applied in these programs. METHODS: Thirty five volunteer workers from ten different companies located in Valencia and Alicante (Spain) agreed to participate. Field work was developed in 2009. Three complementary approaches were applied: reproducibility in two administrations of the questionnaire; comparing data in the questionnaire with data from direct observation of workplaces; and comparing data in the questionnaire with data from routine reports of health surveillance and risk assessment in participating companies. RESULTS: Agreement indices (weighted kappa, wK) in reproducibility analyses for musculoskeletal symptoms in the different parts of the body (thighs being the only exception) were between 0.32 (95%CI 0.05-0.59) and 0.70 (95%CI 0.41-0.99). In general, the same analyses for exposure to the different ergonomic risks yielded lower agreement indices; e.g., wK for neck positions between 0.36 (backwards, 95%CI 0.11-0.61) and 0.55 (forwards, 95%CI 0.30-0.80). In the analyses comparing with data from workplace observation, agreement indices were lower. Most items in the questionnaire show acceptable levels of agreement in reproducibility analyses, but lower indices when comparing with observation. CONCLUSIONS: Most of musculoskeletal symptoms and physical demands self-reported by the workers in the questionnaire were not included in the companies' routine health surveillance and risk assessment reports. The questionnaire is a more sensitive tool than routine health surveillance and risk assessments practices in order to identify perceived problems by workers.

Measuring recovery: Validity of the "Recovery Process Inventory" and the "Recovery Attitudes Questionnaire"  

UK PubMed Central (United Kingdom)

Considerable lack of publications and inconsistent results on construct validity make it difficult to choose an appropriate instrument to measure recovery. The aim of the present study was to evaluate additional psychometric aspects of two established measures of personal recovery with differing focusses. Bivariate associations of the recovery measures with personal, clinical and subjective factors were conducted as indicators of concurrent (convergent and divergent) validity. The scales were also tested concerning internal consistency. The sample comprised of 81 inpatients on an acute psychiatric ward (main diagnoses: 27% substance-related disorders, 27% schizophrenic disorders, 25% affective disorders, 10% neurotic or stress-related disorders, and 11% personality disorders). The "Recovery Attitudes Questionnaire (RAQ)" has to be reevaluated before further administration due to serious psychometric shortcomings concerning internal consistency and concurrent validity. The "Recovery Process Inventory (RPI)" total scale showed acceptable concurrent and within-scale validity and can be recommended in order to measure the personal recovery process for clinical and scientific purposes.

Validity of two common asthma-specific quality of life questionnaires: Juniper mini asthma quality of life questionnaire and Sydney asthma quality of life questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background This study explored the psychometric properties (internal consistency, construct validity, discriminative ability) of the Juniper Mini Asthma Quality of Life Questionnaire (Mini AQLQ-J) and the Sydney Asthma Quality of Life Questionnaire (AQLQ-S). Methods One hundred fourty-six adults (18–45?years) with asthma requiring regular inhaled corticosteroids were recruited to a trial of written emotional disclosure. Correlational analyses were performed to understand the relationship of the two measures with each other, with symptoms, lung function, asthma control, asthma bother and generic quality of life. Median quality of life scores were compared according to gender, health care usage and levels of asthma severity. Results AQLQ-J and AQLQ-S total scores correlated strongly with each other (rho?=??0.80) and moderately with the EuroQol Current Health Status Scale (AQLQ-J: rho?=?0.35; AQLQ-S: rho?=??0.40). Domain score correlations between AQLQ-J and AQLQ-S were mostly moderate (0.50?rho? Both QoL measures were significantly correlated with symptom score. Correlations with the symptom score asthma module (AQLQ-J: rho?=??0.69; AQLQ-S: rho?=?0.50) were stronger compared with the total symptom score and the symptom score rhinitis module (AQLQ-J: rho?=??0.41; AQLQ-S: rho =0.31). Neither QoL measure was significantly correlated with FEV1, % predicted at the total or the domain level. Total scores of both measures were significantly correlated with subjective asthma control (AQLQ-J: rho?=?0.68; AQLQ-S: rho?=??0.61) and asthma bother (AQLQ-J: rho?=??0.73; AQLQ-M: rho?=?0.73). Total AQLQ-J score and total AQLQ-S score were significantly associated with perceived asthma severity (AQLQ-J: p=0.004, AQLQ-S: p=0.002) and having visited a GP in the past four months (AQLQ-J: p=0.003, AQLQ-S: p=0.002). Conclusions This study provides further evidence for the validity of the AQLQ-J and the AQLQ-S in a British population of adult patients with asthma managed in primary care. Correlations with lung function parameters were weak or absent. Correlations with generic quality of life were moderate, those with asthma symptoms, asthma control and asthma bother were strong. Both measures are able to discriminate between levels of asthma severity and health care usage.

Concurrent validity of the modified International Physical Activity Questionnaire for French obese adolescents.  

Science.gov (United States)

Physical activity is an important component of a healthy lifestyle. Evaluating and promoting this activity warrants careful attention, particularly in the context of preventing obesity associated with low physical activity. The aim of the present study was to assess the concurrent validity of a modified, long, self-administered version of the International Physical Activity Questionnaire (IPAQ) using triaxial accelerometry in 56 youth with obesity. The participants' physical activity was measured with an RT3 accelerometer (objective measure) and with the International Physical Activity Questionnaire for Adolescents (IPAQ-A; subjective measure). Although the two methods were correlated strongly (r = .84), there was a significant difference between the two methods. The participants' subjective ratings on the IPAQ-A overestimated the objective measure. Although activity questionnaires are simple and widely used in assessing physical activity, alternative methods should be used when measuring physical activity in youth with obesity. PMID:23829140

Validation of an adapted arabic version of fibromyalgia syndrome impact questionnaire.  

Science.gov (United States)

Fibromyalgia (FM) is the most common chronic pain syndrome encountered in medical practice, affecting females more than males, and the estimated prevalence of FM in Egypt is 1.3 %. The aim was to translate and adapt the Fibromyalgia Impact Questionnaire (FIQ) into Arabic and assess reliability and validity. The Arabic version of Fibromyalgia Impact Questionnaire (FIQ-A) was adapted following the forward/backward translation approach. Fifty-one female patients with FM were studied to assess psychometric properties of the FIQ-A. Reliability was analyzed by the correlation coefficient between test and retest. Internal consistency was checked by the Cronbach's alpha coefficient. Construct validity was assessed comparing FIQ-A with Health Assessment Questionnaire (HAQ), Health Assessment Questionnaire of Fibromyalgia (FHAQ), The Medical Outcome Survey Short-Form-36 (SF-36), and the Total Visual Analog Scale (TVAS) for FM symptom, and feasibility was assessed by the time taken in completing the FIQ-A and the proportion of patients completed the questionnaire. Patients studied were 33.2 ± 9.8 years old. Translation was concordant. Adaptation affected 4 sub-items of physical function. Test-retest correlation coefficient was 0.89 for total FIQ-A and Cronbach's alpha was 0.76. Excellent to good statistically significant correlations (p < 0.05) were found between the FIQ-A items and HAQ, FHAQ, and SF-36. The FIQ-A is a reliable, valid for measuring health status and physical function in Arabic-speaking FM patients. PMID:23681020

Translation, adaptation and validation of the Roland-Morris questionnaire - Brazil Roland-Morris  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of the present study was to translate the Roland-Morris (RM) questionnaire into Brazilian-Portuguese and adapt and validate it. First 3 English teachers independently translated the original questionnaire into Brazilian-Portuguese and a consensus version was generated. Later, 3 other translators, blind to the original questionnaire, performed a back translation. This version was then compared with the original English questionnaire. Discrepancies were discussed and solved by a panel of 3 rheumatologists and the final Brazilian version was established (Brazil-RM). This version was then pretested on 30 chronic low back pain patients consecutively selected from the spine disorders outpatient clinic. In addition to the traditional clinical outcome measures, the Brazil-RM, a 6-point pain scale (from no pain to unbearable pain), and its numerical pain rating scale (PS) (0 to 5) and a visual analog scale (VAS) (0 to 10) were administered twice by one interviewer (1 week apart) and once by one independent interviewer. Spearman's correlation coefficient (SCC) and intraclass correlation coefficient (ICC) were computed to assess test-retest and interobserver reliability. Cross-sectional construct validity was evaluated using the SCC. In the pretesting session, all questions were well understood by the patients. The mean time of questionnaire administration was 4 min and 53 s. The SCC and ICC were 0.88 (P<0.01) and 0.94, respectively, for the test-retest reliability and 0.86 (P<0.01) and 0.95, respectively, for interobserver reliability. The correlation coefficient was 0.80 (P<0.01) between the PS and Brazil-RM score and 0.79 (P<0.01) between the VAS and Brazil-RM score. We conclude that the Brazil-RM was successfully translated and adapted for application to Brazilian patients, with satisfactory reliability and cross-sectional construct validity.

Validity of building characteristics and dorm dampness obtained in a self-administrated questionnaire  

DEFF Research Database (Denmark)

A self-administrated questionnaire used in a cross-sectional study on associations between environmental factors and allergies was validated by building inspections and physical measurements. The agreement was good between the reports from occupants and inspectors regarding technical characteristics, such as type of surface materials etc., but a poor to slight agreement (kappa<0.2) regarding on assessments of moisture damages, such as mould or damp spots, and a mouldy smell, between occupants and inspectors. Dampness problems reported by occupants were associated with health effects (case status), while such problems observed by inspectors were not. The air relative humidity was slightly higher, during winter time, in rooms with condensation on windowpanes. The results indicate that questionnaire surveys give valid data regarding most technical characteristics. With regard to moisture damages, occupants reports seem more relevant than inspector reports, in a study of health.

Validation of a Questionnaire for Heat Strain Evaluation in Women Workers  

Science.gov (United States)

Introduction: Physiological, anthropometrical and thermal perceptual are the most important factors affecting thermoregulation of men and women in workplaces. The purpose of this study was determining the validity of a questionnaire method for assessing women's heat strain in workplaces. Methods: This cross-sectional study was carried out on 96 healthy women. Data were continuously collected over a period of 3 months (July-September) in 2012. Mean ± (SD) of age was found to be 31.5 ± 7.48 years, of height 1.61 ± 0.05 m, of weight 61.55 ± 10.35 kg, and of body mass index 23.52 ± 3.75 kg/m2 in different workplaces. Heart rate and oral temperature were measured by heart rate monitoring and a medical digital thermometer, respectively. Subjects completed a draft questionnaire about the effective factors in the onset of heat strain. After collecting the questionnaires, the data were analyzed by applying Cronbach’sa calculation, factor analysis method, Pearson correlation and receiver operator characteristic curves using the SPSS 18 software. Results: The value for Cronbach's ? was found to be 0.68. The factor analysis method on items of draft questionnaire extracted three subscale (16 variables) which they explained 63.6% of the variance. According to the results of receiver operator characteristic curve analysis, the cut-off questionnaire score for separating people with heat strain from people with no heat strain was obtained to be 17. Conclusions: The results of this research indicated that this quantitative questionnaire has an acceptable reliability and validity, and a cut-off point. Therefore it could be used in the preliminary screening of heat strain in women in warm workplaces, when other heat stress evaluation methods are not available.

Validation of a self-report comorbidity questionnaire for multiple sclerosis.  

UK PubMed Central (United Kingdom)

BACKGROUND/AIMS: Researchers increasingly recognize the high frequency of comorbidity in multiple sclerosis (MS) and the negative impact on quality of life and disability, but little work has evaluated methods of comorbidity measurement in MS. We aimed to validate a self-report questionnaire for assessing comorbidity in MS. METHODS: Patients with MS were recruited from the MS Clinic in Winnipeg, Canada and the Mellen Center (Cleveland Clinic, Cleveland, Ohio, USA) from October 2008 to 2009. Using a questionnaire, participants reported the presence or absence of 36 comorbidities, sociodemographic characteristics, and disability status. Abstractors blinded to questionnaire results collected data regarding the comorbidities of interest and their treatments. Using the medical record as the gold standard, we determined the sensitivity, specificity, positive and negative predictive values of the questionnaire data. To measure agreement we calculated kappa (kappa) statistics. RESULTS: We enrolled 404 participants. Agreement between self-report and medical records was high (kappa >0.82) for diabetes and hypertension; substantial (kappa = 0.62-0.80) for hyperlipidemia, thyroid disease, glaucoma, and lung disease; moderate (kappa = 0.43-0.56) for osteoporosis, irritable bowel syndrome, migraine, depression, heart disease, and anxiety disorders. Agreement was slight to fair for the remaining comorbidities. CONCLUSIONS: Self-report is a valid way to capture comorbidities affecting MS patients.

The Construct Validation of a Questionnaire of Social and Cultural Capital  

Directory of Open Access Journals (Sweden)

Full Text Available The present study was conducted to construct and validate a questionnaire of social and cultural capital in the foreign language context of Iran. To this end, a questionnaire was designed by picking up the most frequently-used indicators of social and cultural capital. The Factorability of the intercorrelation matrix was measured by two tests: Kaiser-Meyer-Olkin test of Sampling Adequacy (KMO) and Bartlett’s Test of Sphericity. The results obtained from the two tests revealed that the factor model was appropriate. To validate the questionnaire, Exploratory Factor Analysis (EFA) was performed. The application of the Principle Component Analysis to the participants’ responses resulted in 14 extracted factors accounting for 69% of the variance. The results obtained from the Scree Test indicated that a five-factor solution might provide a more parsimonious grouping of the items in the questionnaire. The rotated component matrix indicated the variables loaded on each factor so that the researchers came up with the new factors, i.e., social competence, social solidarity, literacy, cultural competence, and extraversion. Finally, statistical results were discussed and suggestions were made for future research.

International Physical Activity Questionnaire: validation and assessment in an Italian sample  

Directory of Open Access Journals (Sweden)

Full Text Available Background: A standardized method for the assessment of physical activity, the International Physical Activity Questionnaire (IPAQ), was developed in the late 1990s as instrument for cross-national assessment. This study aims to evaluate the reliability and validity of the IPAQ short and long version questionnaire in a Italian sample.Methods: The long and short versions of IPAQ questionnaires were administered twice, with an interval of one day between each administration, to 2 different random samples. Cronbach’s alpha was used as a measure of the internal consistency of the two versions.Results: The long version was administered to 60 subjects and the short version to 58. The Cronbach’s alpha on items about physical activity in the long version was 0.73, and 0.60 for the short version. The referred comments on short and long version were not very different both in number and content though they suggest a better understanding of the short version compared to the long one.Discussion: IPAQ short and long versions show acceptable reliability properties in the Italian adult setting. The utilization of a questionnaire seems be more influenced by time of administration and number of requested information. In terms of internal consistency and validity they appear to have similar performance.

The reliability and validity of the Chinese version of nurses' self-concept questionnaire.  

UK PubMed Central (United Kingdom)

AIM: To examine the reliability and validity of the Chinese version of nurses' self-concept questionnaire. BACKGROUND: Nurses' self-concept is important to alleviate the current shortage of nurses. Nurses' self-concept questionnaire is an effective instrument to measure nurses' self-perception of professional competencies. However, the psychometric properties of the Chinese version have not been tested. METHODS: A two-stage research design was used in this study. At Stage 1347 registered nurses were recruited to establish the psychometric properties of the Chinese version. At Stage 2, a confirmatory factor analysis was used to examine the extracted factor structure from Stage 1 with 1017 respondents as a sample. RESULTS: The internal consistency of the Chinese version was 0.95 and the test-retest reliability was 0.83. The exploratory factor analysis extracted six dimensions. The findings at Stage 2 showed an acceptable model fit and discriminant validity. The Chinese version was a significant predictor of Maslach Burnout Inventory (? = -0.58; P = 0.00). CONCLUSIONS: This study verified the psychometric properties of the Chinese version of nurses' self-concept questionnaire. IMPLICATION FOR NURSING MANAGEMENT: The Chinese version of nurses' self-concept questionnaire will facilitate the evaluation of professional self-concept among nurses and help to develop the individualized self-concept strategies.

The Prostate Care Questionnaire for Patients (PCQ-P): Reliability, validity and acceptability  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background In England, prostate cancer patients report worse experience of care than patients with other cancers. However, no standard measure of patient experience of prostate cancer care is currently available. This paper describes an evaluation of the reliability, validity and acceptability of the PCQ-P, a newly developed instrument designed to measure patient experience of prostate cancer care. Methods The reliability, acceptability and validity of the PCQ-P were tested through a postal survey and interviews with patients. The PCQ-P was posted to 1087 prostate cancer patients varying in age, occupation, and overall health status, sampled from five hospitals in England. Nonresponders received one reminder. To assess criterion validity, 935 patients were also sent sections of the National Centre for Social Research Shortened Questionnaire; and to assess test-retest reliability, 296 patients who responded to the questionnaire were resent it a second time three weeks later. A subsample of 20 prostate cancer patients from one hospital took part in qualitative interviews to assess validity and acceptability of the PCQ-P. Acceptability to service providers was evaluated based on four hospitals' experiences of running a survey using the PCQ-P. Results Questionnaires were returned by 865 patients (69.2%). Missing data was low across the sections, with the proportion of patients completing less than 50% of each section ranging from 4.5% to 6.9%. Across the sections of the questionnaire, internal consistency was moderate to high (Cronbach's alpha ranging from 0.63 to 0.80), and test-retest stability was acceptable (intraclass correlation coefficients ranging from 0.57 to 0.73). Findings on criterion validity were significant. Patient interviews indicated that the PCQ-P had high face validity and acceptability. Feedback from hospitals indicated that they found the questionnaire useful, and highlighted important considerations for its future use as part of quality improvement initiatives. Conclusion The PCQ-P has been found to be acceptable to patients and service providers, and is ready for use for the measurement of patient experience in routine practice, service improvement programmes, and research.

Validity and reliability testing of the Swedish version of Melbourne Decision Making Questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Melbourne Decision-Making Questionnaire (MDMQ) is an attempt to capture and measure coping strategies that people use. The instrument had not previously been translated into Swedish. The aim of this study was to evaluate validity and reliability of the Swedish version of the MDMQ. METHOD: A Swedish translation was performed and back-translated. A group of five pilot readers evaluated content validity. The translated questionnaire was tested among 735 patients, healthcare workers, healthcare students and teachers. A parallel analysis (PA), exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed. RESULT: An initial EFA with a four-factor solution showed a low concordance with the original 22-item four-factor model with a very low Cronbach's alpha in one of the dimensions. However, a second EFA with a three-factor solution showed a good model fit for the Swedish translation of the Melbourne Decision-Making Questionnaire (MDMQ-S) with a satisfactory Cronbach's alpha. A CFA showed a goodness of fit after deleting six items. CONCLUSION: After testing the MDMQ-S, we found support for validity and reliability of the instrument. We found the 16-item version of MDMQ-S to be satisfactory concerning the subscales vigilance, procrastination and buck-passing. However, we found no support that the hypervigilance dimension could be measured by the MDMQ-S.

Reliability and validity of the Activity Questionnaire for Adults and Adolescents (AQuAA)  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Accurate measures of physical activity are highly needed. We evaluated the test-retest reliability and construct validity of the self-report Activity Questionnaire for Adults and Adolescents (AQuAA). The AQuAA is a commonly used questionnaire in Dutch youth. Methods In the test-retest reliability study, 53 adolescents and 58 adults completed the AQuAA twice, with an interval of two weeks. In the validity study, 33 adolescents and 47 adults wore an accelerometer (Actigraph) during two weeks, and subsequently completed the AQuAA. Results In adolescents the test-retest reliability was fair to moderate (intraclass correlations (ICCs) ranging from 0.30 to 0.59). In adults the test-retest reliability was fair to moderate for the time spent on sedentary, light and moderate intensity activities (ICCs ranging from 0.49 to 0.60), but poor for time spent on vigorous activities (ICC = -0.005). The correlations between the AQuAA and Actigraph were low and nonsignificant. Compared with the Actigraph, time spent on all physical activities was significantly higher according to the questionnaire (except for light intensity activities in adolescents), while time spent on sedentary behaviours was significantly lower. Conclusion Reliability of the AQuAA is fair to moderate. The validity of the AQuAA compared to an accelerometer is poor. Both adolescents and adults underestimate the time spent on sedentary behaviours and overestimate the time spent on physical activities.

UK PubMed Central (United Kingdom)

OBJETIVE: To validate a tool to measure patient safety culture in Spanish primary care professionals. METHODS: Medical Office Survey on Patient Safety Culture (MOSPSC), from the Agency for Healthcare and Research in Quality (AHRQ). The process has been performed in five steps: original version traslation, conceptual equivalence evaluation, acceptability and viability assessment, content validity and questionnaire test and response analysis and psichometric properties assessment. SETTING: Primary care. SUBJECTS: 185 Primary care professionals from different Spanish regions represented the sample test. MAIN OUTCOME MEASURES: Frecuency, response pattern and discrimination power of each item. Cronbach's alpha coefficient and dimensions obtained through factor analysis. RESULTS: 17, 8% of respondents answered all the items and 28, 7% of them did not answer, or answered the option "Don't know/Does not apply", to one to four items. All the sentences, with only one exception, present discrimination capacity. Cronbach's alpha coefficient results 0,96 and information is sumarized in 15 factors obtaining the same items in 7 of the total 12 factors in the original questionnaire. CONCLUSIONS: Traslated, adapted, extended and validated AHRQ questionnaire is, in this setting, a reliable and useful instrument and it must be used for international comparisons.

Climacteric symptoms and quality of life: validity of women's health questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To evaluate the reliability and validity of the Portuguese version of the Women's Health Questionnaire. METHODS: In order to evaluate the Women's Health Questionnaire (WHQ), an analytical cross-sectional study was carried out at the women's menopause outpatient clinic of a university hospital in São Paulo, Brazil. There were studied 87 women in perimenopause or menopause, defined as experiencing at least one year's absence of menstrual flow. The following variables were collected: demographic data, clinical variables (Kupperman index and correlate numeric scale) and quality of life indexes (SF-36 and utility). RESULTS: The WHQ proved to be a questionnaire easily translated into Portuguese and well-adjusted to Brazilian women. The internal consistency of the overall WHQ was excellent (Cronbach alpha =0.83; 95% CI: 0.71-0.91). Test-retest reliability was also excellent (intraclass correlation coefficient [ICC]=0.92; 95% IC: 0.86-0.96) and had good absolute agreement (0.84; 95% CI: 0.71-0.92). A satisfactory clinical validity was observed. The construct validity was corroborated by clear associations with others scales. A good index of responsiveness after the intervention was reached. CONCLUSIONS: The Portuguese version of the WHQ is of easy and fast administration and understanding. Its measuring properties were related, allowing its use in the evaluation of Brazilian climacteric women's quality of life for various purposes.

Validation of the WHOQOL-BREF quality of life questionnaire for general use in New Zealand: confirmatory factor analysis and Rasch analysis.  

UK PubMed Central (United Kingdom)

PURPOSE: The present study validated the abbreviated version of the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire for general use in New Zealand. METHODS: A random postal sample from the national electoral roll was used, and 808 questionnaires were returned. Psychometric properties of the instrument were assessed, including tests of the four-domain factor structure using confirmatory factor analysis and Rasch analysis. RESULTS: Goodness-of-fit from the confirmatory factor analysis were good, and the overall conclusion of the Rasch analysis supported the confirmatory factor analysis (CFA) findings after dealing with problems of threshold ordering, local dependency, and differential item functioning (DIF). CONCLUSIONS: The WHOQOL-BREF is valid for general use in New Zealand. In the future work, the WHOQOL-BREF domain scores should either be analyzed using non-parametric statistics or data should be fitted to the Rasch model to derive interval person estimates.

[Validation of the SCOFF questionnaire for screening of eating disorders in university women].  

UK PubMed Central (United Kingdom)

BACKGROUND: The prevalence of eating disorders has been steadily increasing in recent years. This has led to a growing sense that instruments are necessary for early detection in high risk populations. OBJECTIVE: Herein the SCOFF (sick, control, one, fat, food) questionnaire was examined for its internal consistency, reliability, and criterion validity in screening eating disorders among university women. MATERIALS AND METHODS: A sample of 385 students was selected at random from six schools in the Universidad Autonóma de Bucaramanga, Colombia, and were evaluated independently with the SCOFF questionnaire and a CIDI (Composite International Diagnostic Interview). RESULTS: A total of 149 (38.7%) students were positive for eating disorder syndromes according to the SCOFF questionnaire, whereas 82 (21.2%) students met eating disorder using the CIDI. SCOFF questionnaire sensitivity was 78.4% (95%CI 64-88%), specificity 75.8% (95%CI 69-82%), ROC curve area 0.823 (95%CI 0.76-0.89), Cronbach's alpha 0.480, Cohen's kappa 0.433 (95%CI 0.32-0.55), and test-retest concordance 91.6% (95%CI 86-96). CONCLUSION: These data indicate the SCOFF questionnaire to be a good scale in screening for eating disorders among university women. Its added advantages are that the test is simple and brief.

[Linguistic adaptation into Spanish and validation of the Arthritis Treatment Satisfaction Questionnaire].  

UK PubMed Central (United Kingdom)

BACKGROUND AND OBJECTIVE: Linguistic adaptation and validation into Spanish of the ARTS questionnaire, a self reported instrument designed to measure four osteoarthritis treatment satisfaction dimensions: treatment advantages, treatment convenience, apprehension about treatment and satisfaction with medical care. MATERIAL AND METHOD: Adaptation was performed using conceptual equivalence, supervised by a panel of 6 experts and 4 independent translators, who were in charge of performing translation and back-translation of the items. A sample of patients suffering from knee, hip or column osteoarthritis was used to estimate the psychometric properties of feasibility, reliability, validity and sensitivity to change. Three groups were identified: adequate analgesic effect and tolerability, treatment-switch because of a weak analgesic effect, and treatment- switch due to poor tolerability. The ARTS was administered at baseline, 1 week later for retest, and after 4 weeks of treatment with NSAIDs or Cox II-inhibitors. RESULTS: A sample of 163 patients was formed (67.7 [9.2] years old). No floor or ceiling effects were found, items were well understood and non- response rates were below 1%. Cronbach's alpha for the total scales was 0.85, and the intraclass correlation coefficient was 0.81. Exploratory factor analysis yielded 4 dimensions which were coherent with those proposed by the original authors. Concurrent validity was measured with SF-36, a pain VAS instrument, a treatment compliance VAS, and the Morisky-Green compliance questionnaire. The adapted instrument showed a good discriminatory validity, and it was able to distinguish between patients needing a change in treatment and those who did not need it. It was also sensitive to changes in patients' treatment effectiveness after a 30 days follow up. CONCLUSIONS: A psychometrically valid and conceptually equivalent ARTS questionnaire has been produced to explore satisfaction with treatment in patients with osteoarthritis in Spanish speaking countries.

Psychometric validation of the overactive bladder satisfaction with treatment questionnaire (OAB-SAT-q).  

UK PubMed Central (United Kingdom)

AIMS: Valid and reliable questionnaires must be used to accurately assess patients' satisfaction with overactive bladder (OAB) treatment. This study evaluated the reliability and validity of the OAB Satisfaction with Treatment Questionnaire (OAB-SAT-q). METHODS: This was a secondary analysis of clinical study data of patients randomized to darifenacin or darifenacin plus Behavioral Modification Program. Patients completed the Overactive Bladder Questionnaire (OAB-q) and a 3-day bladder diary at Baseline and Week 12 and the OAB-SAT-q at Week 12. Internal consistency reliability was assessed by Cronbach's alpha. Concurrent validity was assessed through correlations with OAB-q change scores and adverse events (AEs). Discriminant validity was assessed among subgroups using general linear models. RESULTS: Analyses utilized a per-protocol population (completion of OAB-q at Baseline and OAB-q and OAB-SAT-q at Week 12) (n = 375). Exploratory factor analysis of the OAB-SAT-q revealed three 3-item subscales (Satisfaction, Side Effects, Endorsement) and two single items (Convenience, Preference). Cronbach's alphas = 0.84-0.95. Subscale-to-subscale correlations = 0.10-0.67 (all P < 0.01 except Side Effects and Convenience). The Side Effects subscale significantly correlated with number of treatment-related AEs (r = 0.27; P < 0.01) and discriminated between patients with/without dry mouth and patients with/without constipation. The Satisfaction and Endorsement subscales discriminated between patients who worsened or had no change in micturition frequency and urinary urgency and patients who had a reduction of >3 episodes (all P < 0.001). The OAB-SAT-q does not appear to discriminate by incontinence episodes. CONCLUSION: The OAB-SAT-q demonstrated good psychometric properties in this initial evaluation-including internal consistency reliability and concurrent and discriminant validity-and appears to be a useful assessment of OAB treatment satisfaction.

Validation of the Mandarin version of the LittlEARS® Auditory Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVES: To evaluate the psychometric properties of the Mandarin version of the LittlEARS(®)Auditory Questionnaire and to compare the parameters with those of the original German version of the questionnaire. The results would indicate whether the Mandarin version of the questionnaire can be applied in Mandarin speaking children or not. METHODS: A "back-translation" method was used to translate and adapt the LittlEARS(®) Auditory Questionnaire into Mandarin. A group of 157 Mandarin speaking parents of children below 24 months of age with normal hearing completed the LittlEARS(®) Auditory Questionnaire. Various psychometric analyses (scale analysis and item analysis) were conducted and compared with the original German version. RESULTS: The following scale characteristics were found with the above sample: internal consistency: Cronbach's alpha = 0.945; reliability: split-half r = 0.914; predictive accuracy: Guttman's lambda = 0.882; correlation between overall score and age of the children: r = 0.841. Several parameters (correlation between age and item score, index of difficulty, discrimination coefficient) of each item were also calculated. The regression curve, which reflects the age-dependence of auditory behavior, was produced. All parameters above had no significant differences with the corresponding ones of the original German version. Standardized values (expected and minimum values) of the Mandarin LittlEARS(®) Auditory Questionnaire were provided. CONCLUSION: The Mandarin version of the LittlEARS(®) Auditory Questionnaire is reliable and valid as a sensitive tool to assess the development of auditory behavior in Mandarin speaking children up to 24 months of age. The Mandarin standardized values are helpful for clinicians to reach a preliminary judgment in children's hearing screening or for parents to monitor the auditory development of their hearing-impaired children.

The EORTC information questionnaire, EORTC QLQ-INFO25. Validation study for Spanish patients.  

UK PubMed Central (United Kingdom)

INTRODUCTION: The EORTC QLQ-INFO25 evaluates the information received by cancer patients. This study assesses the psychometric properties of the QLQ-INFO25 when applied to a sample of Spanish patients. MATERIALS AND METHODS: A total of 169 patients with different cancers and stages of disease completed the EORTC QLQINFO25, the EORTC QLQ-C30 and the information scales of the inpatient satisfaction module EORTC IN-PATSAT32 on two occasions during the patients' treatment and follow- up period. Psychometric evaluation of the structure, reliability, validity and responsiveness to changes was conducted. Patient acceptability was assessed with a debriefing questionnaire. RESULTS: Multi-trait scaling confirmed the 4 multi-item scales (information about disease, medical tests, treatment and other services) and eight single items. All items met the standards for convergent validity and all except one met the standards of item discriminant validity. Internal consistency for all scales (?>0.70) and the whole questionnaire (?>0.90) was adequate in the three measurements, except information about the disease (0.67) and other services (0.68) in the first measurement, as was test-retest reliability (intraclass correlations >0.70). Correlations with related areas of IN-PATSAT32 (r>0.40) supported convergent validity. Divergent validity was confirmed through low correlations with EORTC QLQ-C30 scales (r<0.30). The EORTC QLQ-INFO-25 discriminated among groups based on gender, age, education, levels of anxiety and depression, treatment line, wish for information and satisfaction. One scale and an item showed changes over time. CONCLUSIONS: The EORTC QLQ-INFO 25 is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the EORTC validation study.

Validation of a patient satisfaction questionnaire for services provided in Spanish community pharmacies.  

UK PubMed Central (United Kingdom)

BACKGROUND: The concept of Pharmaceutical Care (PC) is being gradually developed, and it's impact in health care should be measured using a quality tool. OBJECTIVE: The aim of this study was to describe and assess the psychometric properties of a patient satisfaction questionnaire (PSQ) for PC services in community pharmacies in Seville, Spain. It was based on a previous questionnaire in Spanish. METHODS: The face and content validity were assessed using the items of a validated questionnaire developed by Traverso et al. and adapted to the Seville pharmacy patient population. The PSQ was designed for use in the community pharmacy setting by a panel of seven pharmacists with expertise in both PC and questionnaire design. The result, was a 'draft PSQ' which comprised of 27 multidimensional items, with responses recorded on a five-point 'Likert-type scale'. The validity and reliability of the 'final PSQ' was carried out using a cross-sectional and analytical study. Eighteen community pharmacies agreed to participate in the study. The draft PSQ was a self completion questionnaire distributed to patients by pharmacists following selection criteria. The survey response rate was assessed. The validity was determined by establishing the distribution of the PSQ's items and dimensions of the PSQ through factor analysis, and the reliability was evaluated with Cronbach's alpha coefficient (?). RESULTS: Two-hundred and twenty-three patients took part in the study.The factor analysis with varimax rotation established a 'final PSQ' with 24 items over two dimensions: Medication Therapy Management (MTM) and General satisfaction with the pharmacy/staff and services (GSP/SS) which extracted 63.5% of the variance. The internal consistency by ? was 0.964 for the PSQ and 0.959 and 0.916 for the two dimensions, respectively. The median (mode) score for GSP/SS was 5.0 (5.0) and 4.0 (5.0) for MTM. The Wilcoxon-test indicated that the difference between these scores was statistically significant (P < 0.001). CONCLUSION: Our results suggest that the PSQ is a two dimensional instrument with psychometric properties able to assess patient satisfaction in community pharmacies. However, its validity and reliability need to be further confirmed in different PC settings and its sensitivity to measure changes in satisfaction over time also needs to be established.

Validity and reliability of the Food-Life Questionnaire. Short form.  

Science.gov (United States)

Measures of beliefs and attitudes towards food need to be valid, and easy to use and interpret. The present study aimed to establish the validity and reliability of a short-form of the Food-Life Questionnaire (FLQ). Participants (247 females; 118 males), recruited in South Australia, completed a questionnaire in 2012 incorporating the original FLQ, a revised short form (FLQ-SF), and measures of food choice and consumption. Validity (construct, criterion-related, and incremental) and reliability (internal consistency and short-form) were assessed. Factor analysis established that short-form items loaded onto five factors consistent with the original FLQ and explained 60% of variance. Moderate correlations were observed between the FLQ-SF and a measure of food choices (r=.32-.64), and the FLQ-SF predicted unhealthy food consumption over and above the full FLQ demonstrating criterion-related and incremental validity respectively. The final FLQ-SF included 21 items and had a Cronbach's alpha of .75. Short-form reliability was established with correlations between corresponding subscales of the FLQ and FLQ-SF ranging from r=.64-.84. Overall, the FLQ-SF is brief, psychometrically robust, and easy to administer. It should be considered an important tool in research informing public policies and programs that aim to improve food choices. PMID:23856433

[Validation of a questionnaire to evaluate the female sexual function in postmenopausal women].  

UK PubMed Central (United Kingdom)

PURPOSE: to generate and validate a proper questionnaire to evaluate the sexual function in post-menopause women. METHODS: 251 women, within 2 to 15 years postmenopause, were included in the study. Questionnaire's reproductibility/reliability was evaluated by Pearson, intraclass and Lin's correlation coefficients. The internal consistance was examined by the Cronbach's alpha coefficient. Classical item theory guidelines were used for face, content and construct validation. RESULTS: an instrument with 57 items and nine domains was generated. Fourteen questions (24.5%) were eliminated by either poor correlation with the scale or low discriminative power. The final version with 43 items has shown good reproductibility (r=0.719, 95%CI=0.690-0.750; pc=0.887; 95%CI=0.850-0.930; p<0.001). Internal consistance was also adequate (alpha=0.951). About 60% of the reviewers have confirmed face and content validation. The construct validation was assessed by the Cronbach alpha 0.951. CONCLUSIONS: it was concluded that the new instrument is appropriate for evaluating the sexual function in post-menopause women.

Further development of the Norbeck Social Support Questionnaire: normative data and validity testing.  

UK PubMed Central (United Kingdom)

This article describes the second phase of testing the Norbeck Social Support Questionnaire (NSSQ), an instrument designed to measure multiple dimensions of social support. Three studies were conducted to provide a normative data base and to further test validity. In the first study, data from 136 employed adults were obtained. The amount and type of support available for a functioning group of male and female respondents and sources of support for this sample are described. In the second and third studies, the instrument was found to be very stable over a seven-month interval and sensitive to changes within the social support networks of a group of graduate students during their first year of study. Construct validity of the instrument was established by comparing convergent and discriminant constructs to the NSSQ. Concurrent validity with another social support questionnaire was demonstrated. Predictive validity was tested in a sample of 53 graduate students through assessing the buffering effect of social support on measures of negative mood following life stress. Two NSSQ subscales, aid and duration of relationships, had significant interaction effects with life stress on the outcome of negative mood. Duration of relationships also had a significant main effect. After subtracting the main effect for life stress from the overall R2 in the multiple regression analysis, the NSSQ functional support subscales and their interactions with life stress accounted for 19 percent of the variance on negative mood, and the NSSQ network property subscales and their interactions accounted for 20 percent of the variance.

Patient satisfaction with hospital rehabilitation: validation of the SAT-16 questionnaire through Rasch analysis.  

UK PubMed Central (United Kingdom)

AIM: The SAT-16 is a 16-item self-administered questionnaire measuring patient satisfaction with the quality of care during stay in a rehabilitation unit. A comprehensive psychometric analysis of SAT-16 was performed using both classical test theory and Rasch analysis (RA) to examine its validity and metric properties, and provide further insights for its clinical use in rehabilitation settings. METHODS: A sample of 9458 patients, consecutively admitted to two Rehabilitation Centres, was examined with SAT-16. Factor (both explorative and confirmatory) analysis and RA were used to process the data in order to examine validity and metric properties of SAT-16. Dimensionality, item fit to the model, response category performance and internal construct validity were assessed. RESULTS: Two subscales were identified by factor analysis and expert review, respectively related to satisfaction with clinical care (items 1-9), and satisfaction with hospital organization and facilities ("hotel" aspects of care, items 10-16). Each subscale underwent a separate RA. Response categories were revised in both subscales of SAT-16, obtaining a new 3-level rating scale. Both subscales showed high internal consistency and internal validity. CONCLUSION: RA confirmed the appropriateness of SAT-16 and its usefulness in identifying areas for quality improvement. Overall, the questionnaire allows to assess patient satisfaction with the services through: 1) two sub-scores respectively specific for satisfaction with "clinical care" and "hotel aspects of care"; 2) additional information gathered in the optional open-ended questions.

Design and validity of a questionnaire to assess sexuality in pregnant women  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background A review of validated methods for assessing female sexual dysfunction and a review of male and female sexual dysfunction did not refer to any specific questionnaire for evaluating sexuality during pregnancy. A study was performed at the Obstetrics and Gynecology Department of Botucatu Medical School, São Paulo State University, Brazil to design and validate a pregnancy sexuality questionnaire, the Pregnancy Sexual Response Inventory (PSRI). Methods Women with a singleton pregnancy between 10 and 35 weeks of gestation were randomly recruited. There were five phases in the development of the PSRI: (1) item selection; (2) item development; (3) determination of internal consistency, reliability and convergence; (4) content validity; and (5) determination of inter-interviewer reliability. Internal consistency and reliability were evaluated using Cronbach's alpha. Inter-interviewer reliability was assessed by evaluating the responses of 18 academics at various institutions, using Kappa Index and Student t test. Results Good internal consistency and reliability were obtained (Cronbach's alpha coefficient = 0.79). Among the 18 academics, 13 totally agreed (K = 1.0), three partially agreed (K = 0.67) and two disagreed (K = 0.33) with the proposed questions. Comparisons of the mean PSRI domain scores made between the primary investigators and the other interviewers showed no significant differences in all domains (p > 0.05). Conclusion PSRI is a new validated instrument for evaluating sexuality and sexual activity and related health concerns during pregnancy.

VALIDITY OF THE MODIFIED CONCONI TEST FOR DETERMINING VENTILATORY THRESHOLD DURING ON-WATER ROWING  

Directory of Open Access Journals (Sweden)

Full Text Available The objectives of this study were to design a field test based on the Conconi protocol to determine the ventilatory threshold of rowers and to test its reliability and validity. A group of sixteen oarsmen completed a modified Conconi test for on-water rowing. The reliability of the detection of the heart rate threshold was evaluated using heart rate breaking point in the Conconi test and retest. Heart rate threshold was detected in 88.8% of cases in the test-retest. The validity of the modified Conconi test was evaluated by comparing the heart rate threshold data acquired with that obtained in a ventilatory threshold test (VT2). No significant differences were found for the values of different intensity parameters i.e. heart rate (HR), oxygen consumption (VO2), stroke rate (SR) and speed (S) between the heart rate threshold and the ventilatory threshold, (170.9 ± 6.8 vs. 169.3 ± 6.4 beats·min-1; 42.0 ± 8.6 vs. 43.5 ± 8.3 ml·kg-1·min-1; 25.8 ± 3.3 vs. 27.0 ± 3.2 strokes·min-1 and 14.4 ± 0.8 vs. 14.6 ± 0.8 km·h-1). The differences in averages obtained in the Conconi test-retest were small with a low standard error of the mean. The reliability data between the Conconi test-retest showed low coefficients of variations (CV) and high intraclass correlation coefficients (ICC). The total errors for the Conconi test-retest are low for the measured variables (1.31 HR, 0.87 VO2, 0.65 SR, and 0.1 S). The Bland- Altman's method for analysis validity showed a strong concordance according to the analyzed variables. We conclude that the modified Conconi test for on-water rowing is a valid and reliable method for the determination of the second ventilatory threshold (VT2).

Validity and reliability of short form-12 questionnaire in Iranian hemodialysis patients  

DEFF Research Database (Denmark)

INTRODUCTION: The aim of the study was to assess the validity and reliability of the SF-12 questionnaire in a sample of Iranian patients undergoing hemodialysis. MATERIALS AND METHODS: One hundred and forty-four hemodialysis patients were included from dialysis centers in Zanjan, Iran, and were asked to complete the SF-12 and SF-36 questionnaires. An initial test-retest reliability evaluation was performed on a sample of 70 patients from the total group, with a retest interval of 14 days. Reliability was estimated by internal consistency and validity was assessed using known-group comparisons and construct validity on the patient group as a whole. A linear regression analysis was used to assess any variation in the physical component summary and mental component summary scores of the SF-36 with the respective component summary scores of the SF-12. In addition, the factor structure of the questionnaire was extracted by performing a confirmatory factor analysis. RESULTS: Cronbach alpha for physicaland mental component summaries were 0.89 and 0.90, respectively. The SF-12 showed a good discriminatory ability between subgroups of patients based on demographic and clinical variables. The confirmatory factor analysis for the original two-factor structure showed a good fit index (chi2 = 23.30, degrees of freedom = 13), goodness-of-fit index = 0.96, and root mean squared error of approximation = 0.079). CONCLUSIONS: In general, the SF-12 has good psychometric properties and can be used as a shorter version of the SF-36 questionnaire in future studies involving Iranian patients undergoing hemodialysis.

[Polish adaptation and validation of the Visual Function Questionnaire (VFQ-25) in multiple sclerosis patients].  

UK PubMed Central (United Kingdom)

INTRODUCTION: Visual disturbances very often accompany of multiple sclerosis (MS) and affect patients' quality of life (QoL). There have been no tools for investigation of the effect of visual disturbances on QoL in MS patients available in Poland. The aim of this study was validation analysis of Polish adaptation of Visual Function Questionnaire VFQ-25. MATERIAL AND METHODS: VFQ-25 published by Mangione in 2001, consists of 25 questions concerning general well-being, assessment of vision, social functioning, mental health, and self-sufficiency. According to the applicable translation principles, the original English version was adapted into Polish, and validation analysis of the convergent validity as well internal reliability was carried out. 108 randomly selected patients, diagnosed with MS according to McDonald's criteria were included in this study: 63 women and 45 men aged on the average 37.8 +/- 9.2 years, with mean disease duration of 11.2 +/- 5.6 years. All patients underwent assessment of disability based on Expanded Disability Status Scale (EDSS). Besides the analyzed VFQ-25 questionnaire, the patients completed also the Functional Assessment of Multiple Sclerosis (FAMS) questionnaire and SF-36 Health Survey. RESULTS: The internal consistency of the questionnaire was satisfactory (Cronbach's alpha reached 0.95). The accuracy of the scale was confirmed by positive correlations of the results between VFQ-25 and EDSS, FAMS and SF-36. CONCLUSIONS: Statistical analysis has demonstrated that the Polish version of VFQ-25 is a valuable tool for investigation of the effect of visual disturbances on QoL in MS patients.

Prospective evaluation of sacral nerve modulation in children with validated questionnaires.  

UK PubMed Central (United Kingdom)

PURPOSE: Sacral neuromodulation for refractory urinary dysfunction in pediatrics shows promising results. We prospectively evaluated patients undergoing sacral neuromodulation using validated quality of life and bladder dysfunction questionnaires. MATERIALS AND METHODS: All patients were prospectively enrolled in the study. Two validated questionnaires were completed preoperatively, after lead placement and at all followups. The PedsQL™ 4.0 Generic Core Scale, which assesses quality of life and bladder dysfunction, was quantified using the Vancouver Nonneurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome (NLUTD/DES) questionnaire. The Wilcoxon matched pairs test was used for statistical analysis with p <0.05 considered significant. RESULTS: A total of 14 patients with a median age of 10 years were enrolled in the study. Median followup was 6 months. All patients underwent generator placement. No significant difference was seen in physical quality of life. Before and after lead placement mean ± SD psychosocial quality of life scores were 70.6 ± 17.4 and 81.43 ± 14.8 (p = 0.02), mean total quality of life scores were 75 ± 15.3 and 84.04 ± 13.2 (p = 0.006) and median NLUTD/DES scores were 23 ± 7.8 and 10.5 ± 7.0 (p <0.001), respectively. One month postoperatively a significant difference was seen in total quality of life and NLUTD/DES scores. Two patients required replacement of the temporary lead or generator. There were no infections. CONCLUSIONS: Patients undergoing sacral neuromodulation had significant improvement in NLUTD/DES scores, and psychosocial and overall total quality of life. Results were durable at 1 month. Continuing to follow these patients in a prospective manner with validated questionnaires will strengthen the current evidence supporting sacral neuromodulation in the pediatric population.

Validation and practical implementation of a multidisciplinary cancer distress screening questionnaire  

Energy Technology Data Exchange (ETDEWEB)

Background: In order to identify cancer patients with psychosocial needs during radiotherapy, a routine screening questionnaire is widely recommended in the literature. Several tools focusing mainly on psychological issues have been developed during the past decade. However, problems with their implementation into clinical routine have been repeatedly reported, due to a lack of practicability for clinicians and nurses. This study reports the compilation of a multidisciplinary screening questionnaire and an analysis of the effectiveness of its implementation into clinical routine at the Department of Radiotherapy, Medical University of Vienna. Materials and methods: The screening questionnaire is based on a compilation of several subscales from established and validated assessment tools. It focuses on comprehensive information with high a clinical relevance for all professions. In a pilot study, patients' acceptance was assessed qualitatively. Analysis of missing screening data in consecutively admitted patients reflects the effectiveness of implementation and representativity of the data. A validation analysis of the psychological subscales was performed using external criteria and its internal consistency was tested with Cronbachs' {alpha}. Results: Qualitative patient acceptance of the screening questionnaire is good. The overall response rate in the screening procedure was 75 %. Missing patient screening data sets arose randomly - mainly due to organizational problems - and did not result in systematic errors. The psychological subscales identify highly distressed patients with a sensitivity of 89 and 78 %, and an internal consistency of 0.843 and 0.617. Conclusion: The multidisciplinary screening questionnaire compiled in this study has a high patient acceptance, provides reliable and representative data and identifies highly distressed patients with excellent sensitivity. Although requiring additional personnel resources, it can be implemented successfully in clinical routine with benefits for both the patient and the professional team. (orig.)

Cross-cultural adaptation and validation of Behçet's disease quality of life questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Currently, there is one Behçet's disease (BD) specific self reporting questionnaire developed and published in the literature, The Leeds BD-quality of life (QoL). We conducted a cross-cultural adaptation and validation of the Arabic version of the Leeds BD-QoL Methods A cross-sectional study was conducted among 41 consecutive patients attending rheumatology clinics at the American University of Beirut Medical Center between June and December 2007. The BD-QoL questionnaire, the Katz Index of Activities of Daily Living (ADL) and the Lawton Instrumental Activities of Daily Living (IADL) questionnaires were co-administered during the same visit, and severity scores were calculated. Cross-cultural adaptation of BD-QoL was performed using forward and backward translations of the original questionnaire. Internal consistency and test-retest reliability of the final version were determined. Exploratory Factor Analysis (EFA) was used to assess the dimensionality of the scale items. External construct validity was examined by correlating Arabic BD-QoL with the severity score, ADL and IADL. Results The 30 items of the adapted Arabic BD-QoL showed a high internal consistency (KR-20 coefficient 0.89) and test-retest reliability (Spearman's test 0.91). The convergence of all 30 items suggests that the 30-item adapted Arabic BD-QoL scale is unidimensional. BD-QoL did not correlate with any of the patients' demographics. Still, it was positively correlated with patient severity score (r 0.4, p 0.02), and IADL (but not ADL). Conclusions This cross-cultural adaptation has produced an Arabic BD-QoL questionnaire that is now available for use in clinical settings and in research studies, among Arabic speaking patients.

Validity and repeatability of the EPIC physical activity questionnaire: a validation study using accelerometers as an objective measure  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background A primary aim of the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort study is to examine the association between total physical activity levels (comprising occupational, household and recreational activity) and the incidence of cancer. We examined the validity and long-term repeatability of total physical activity measurements estimated from the past-year recall EPIC questionnaire, using accelerometers as an objective reference measure. Methods Participants included 100 men and 82 women aged 50–65 years. Criterion validity was assessed by comparing the physical activity estimates from the EPIC questionnaire with total activity estimated from the average of three separate 7-day accelerometer periods during the same (past-year) period. Long-term repeatability of the EPIC questionnaire was assessed by comparing the responses from the baseline and 10-month administrations. Past-year EPIC estimates were also compared with the Friedenreich Lifetime Total Physical Activity Questionnaire to examine whether recent activity reflected lifetime activity. Results Accelerometer total metabolic equivalent (MET)-hours/week were positively associated with a total physical activity index (Spearman rank correlation ? = 0.29, 95% confidence interval (CI) 0.15, 0.42) and with non-occupational activity estimated in MET-hours/week (? = 0.21, 95% CI 0.07, 0.35). Stratified analyses suggested stronger correlations for non-occupational activity for participants who were male, had a lower BMI, were younger, or were not full-time workers, although the differences in correlations between groups were not statistically significant. The weighted kappa coefficient for repeatability of the total physical activity index was 0.62 (95% CI 0.53, 0.71). Spearman correlations for repeatability of components of activity were 0.65 (95% CI 0.55, 0.72) for total non-occupational, 0.58 (95% CI 0.48, 0.67) for recreational and 0.73 (95% CI 0.66, 0.79) for household activity. When past-year activity was compared to lifetime estimates of activity, there was fair agreement for non-occupational (? = 0.26) activity, which was greater for household activity (? = 0.46) than for recreational activity (? = 0.21). Conclusion Our findings suggest that the EPIC questionnaire has acceptable measurement characteristics for ranking participants according to their level of total physical activity. The questionnaire should be able to identify the presence or absence of reasonably strong aetiological associations when either recent or long-term activity is the responsible factor.

Nondisclosure during psychotherapy supervision: Validation of the German version of the Supervisory Questionnaire (SQ).  

UK PubMed Central (United Kingdom)

Abstract Nondisclosure is considered to be a central obstacle to effective psychotherapy supervision. The aim of the current study was the validation of the German version of the Supervisory Questionnaire (SQ; Yourman & Farber, 1996), a short measure for the assessment of supervisee nondisclosure. The investigation was based on a sample of 589 supervisees. Confirmatory factor analyses suggested a two-factor model of the SQ which included one factor describing nondisclosure regarding the patient (?=.74) and another describing nondisclosure regarding the supervisor (?=.71). The SQ demonstrated satisfactory convergent and discriminant validity. Additionally assessed supervisee characteristics accounted for 16% of the variance in nondisclosure. These results provide general support for the reliability and validity of the SQ in a large sample of supervisees.

Validation of the Spanish version of the questionnaire Practice Environment Scale of the Nursing Work Index.  

UK PubMed Central (United Kingdom)

BACKGROUND: The importance of the practice environment in the provision of care and its relation with patient outcomes and nurse-reported outcomes, support the need to have an instrument to measure such practice environment. OBJECTIVE: To evaluate the validity and reliability of the Spanish version of the Practice Environment Scale of the Nursing Work Index (PES-NWI), determining the content validity, test-retest reliability, internal consistency and construct validity. DESIGN: A cross-sectional survey of bedside care nurses undertaken in 2009 in medical, surgical and critical care wards of 33 Spanish National Health Service hospitals with more than 150 beds. METHODS: The validation process followed the internationally recognized guidelines about psychometric properties of instruments: translation and back-translation, content validity, test-retest reliability, internal consistency and construct validity. Other study variables included, like nurses' intention to leave and job satisfaction. RESULTS: The Intraclass Correlation Coefficient (ICC) for an overall score on the 31 item questionnaire was 0.87 (CI 95%: 0.85-0.89). Cronbach's alpha was 0.90 (CI 95%: 0.87-0.93). The weighted Kappa Index obtained for each of the items ranges from 0.24 (CI 95%: 0.22-0.26) to 0.51 (CI 95%: 0.49-0.53). The Content Validity Index score ranges from 0.5 for the item "Opportunities for advancement" to 1. Five of the terms attain this maximum level of agreement: "Active staff development or continuing education programs for nurses", "Enough registered nurses on staff to provide quality patient care", "Enough staff to get the work done", "Management that listens and responds to employee concerns" and "Collaboration between nurses and physicians". CONCLUSIONS: The validation process indicates that the Spanish version of the PES-NWI is valid and reliable in its current version and it can be used to measure the practice environment of Spanish nurses working in clinical practice in hospitals of the Spanish NHS.

Development and validation of a questionnaire assessing fears and beliefs of patients with knee osteoarthritis: the Knee Osteoarthritis Fears and Beliefs Questionnaire (KOFBeQ).  

UK PubMed Central (United Kingdom)

OBJECTIVE: We aimed to develop a questionnaire assessing fears and beliefs of patients with knee OA. DESIGN: We sent a detailed document reporting on a qualitative analysis of interviews of patients with knee OA to experts, and a Delphi procedure was adopted for item generation. Then, 80 physicians recruited 566 patients with knee OA to test the provisional questionnaire. Items were reduced according to their metric properties and exploratory factor analysis. Reliability was tested by the Cronbach ? coefficient. Construct validity was tested by divergent validity and confirmatory factor analysis. Test-retest reliability was assessed by the intra-class correlation coefficient (ICC) and the Bland and Altman technique. RESULTS: 137 items were extracted from analysis of the interview data. Three Delphi rounds were needed to obtain consensus on a 25-item provisional questionnaire. The item-reduction process resulted in an 11-item questionnaire. Selected items represented fears and beliefs about daily living activities (3 items), fears and beliefs about physicians (4 items), fears and beliefs about the disease (2 items), and fears and beliefs about sports and leisure activities (2 items). The Cronbach ? coefficient of global score was 0.85. We observed expected divergent validity. Confirmation factor analyses confirmed higher intra-factor than inter-factor correlations. Test-retest reliability was good, with an ICC of 0.81, and Bland and Altman analysis did not reveal a systematic trend. CONCLUSIONS: We propose an 11-item questionnaire assessing patients' fears and beliefs concerning knee OA with good content and construct validity.

Validation on the simplified medication adherence questionnaire (SMAQ) in renal transplant patients on tacrolimus.  

UK PubMed Central (United Kingdom)

BACKGROUND: Non-adherence to immunosuppressive medication is associated with graft loss and death. The simplified medication adherence questionnaire (SMAQ) is a short and reliable instrument for assessing adherence to medication. OBJECTIVE: Validation of a version of the SMAQ instrument adapted for use in transplant patients in a sample of kidney graft recipients. METHODS: Observational, longitudinal prospective study in 150 renal transplant patients on tacrolimus, over 18 years old, who had received a graft at least one year before. Basic sociodemographic and clinical data were recorded; patients completed the SMAQ twice (administered by doctor/nurse) and self-administered the Morisky-Green scale. The analysis database included 144 patients that met selection criteria and that provided the required data. Descriptive characteristics for all recorded parameters and psychometric characteristics of the questionnaire (reliability and validity) were studied. RESULTS: Mean age in the sample was 50.63 (12.44) years, 60.42% were men. Some 20.14% of patients had sub-target tacrolimus levels (<5 ng/ml), and unjustified variations in immunosuppressive drug levels were reported for 13.48%. Regarding SMAQ results, 39.01%/41.84% of patients were non-adherent (doctor/nurse administration); 22.38% according to the Morisky-Green scale. Interobserver agreement (kappa) was 0.821 (P<.001). The Cramer’s-V statistic for convergent validity was 0.516 (P<.001). SMAQ scores were associated with unjustified variations in tacrolimus levels. In the prediction of tacrolimus levels (target vs subtarget), SMAQ compared to Morisky-Green provided a better classification of patients, with greater sensitivity and lower specificity. CONCLUSION: The questionnaire provides good levels of validity and interobserver agreement. An enhanced sensitivity is advantageous to better detect non-adherent patients for a better follow-up.

Cross-cultural adaptation and validation of the Brazilian version of the Wisconsin Brief Pain Questionnaire.  

UK PubMed Central (United Kingdom)

CONTEXT: Chronic pain is a common complaint among patients with muscular disease. The Wisconsin Brief Pain Questionnaire (WBPQ) has been used to quantify pain severity and pain interference with daily functions. OBJECTIVES: To translate the WBPQ for use with Brazilian patients and to evaluate the psychometric properties of the adaptation. METHODS: We conducted a cross-cultural adaptation of the original English version of the WBPQ for use in Brazil (WBPQ-B) and evaluated the psychometric properties of the adapted version. The original questionnaire was translated, evaluated by an expert panel, pilot tested in 40 patients, and back-translated. Subsequently, the tool was administered, in a cross-sectional study, to 100 adult patients who had muscular disease and were being attended to at our university hospital. RESULTS: We performed a confirmatory factor analysis and assessed the reliability and validity of the questionnaire (Appendix). The two-factor structure (pain intensity and pain interference) was confirmed satisfactorily. Internal consistency for both scales was adequate (Cronbach's alpha = 0.74 and 0.79, respectively), as was the interrater stability (intraclass correlation coefficients = 0.88 and 0.92, respectively). Convergent validity with the 36-Item Short Form Health Survey was supported by confirmation of a priori hypotheses of negative and satisfactory correlations between the WBPQ-B and some of the 36-Item Short Form Health Survey domains. The pain interference scale correlated higher with the mental summary component. Known-group validity analysis showed that the pain intensity items and scale of the WBPQ-B were higher in the groups where patients with exercise intolerance were concentrated. CONCLUSION: We found the WBPQ-B to be a reliable and valid instrument for pain assessment of Brazilians who have muscular disease. The survey presents similar psychometric properties to the original version.

Validation of the Global Health Professions Students Survey questionnaire in Italy  

Directory of Open Access Journals (Sweden)

Full Text Available Background: The World Health Organization, the U.S. Centers for Disease Control and Prevention (CDC), and the Canadian Public Health Association have developed the Global Health Professions Student Survey (GHPSS) questionnaire in order to collect data on tobacco use and cessation counselling among health- profession students. The aims of the study were to evaluate the reliability and validity of the GHPSS questionnaire in Italy among health-profession students and to examine the prevalence of tobacco use, knowledge and attitudes to it and tobacco cessation training among students attending Italian medical schools using the standardised GHPSS approach.Methods: Before testing tobacco use prevalence, knowledge and attitudes, and tobacco cessation training, we calculated the Cronbach’s alpha to assess the internal validity with the intention of avoiding misleading results. The questionnaire was administered to 100 health-profession students and data were collected in March 2009, during regular class sessions among students of two Italian Schools of Medicine. The original GHPSS instrument was translated into the Italian language and modified by adding three specific questions regarding I) the knowledge about the use of antidepressants, ii) Acetylcholine Receptor Partial Agonists, and iii) counselling techniques used in tobacco cessation programs. Statistical analysis was performed using SPSS 13.0, statistical software for windows.Results: Cronbach’s alpha was higher on 17 items (alpha= 0.872), belonging to section I and IV (respectively: “Tobacco Use Prevalenceú and “Behaviour/Cessationú). The addition, also, of only one more of the others items (section)made the alpha value worse. Cronbach’s alpha for section VI for all items together (n. 44 items) was 0.815, which implies that the questionnaire had a very satisfactory internal validity. The prevalence of current smokers was 33%, while only 12% of students declared to be tobacco users. Interestingly, students who were tobacco users were 80% less likely to consider that health professionals needed training on smoking cessation techniques in comparison to non tobacco users.Conclusions: The questionnaire showed excellent reliability properties in the sample studied. In terms of internal consistency and validity, it appears to have an acceptable performance. Given the high prevalence of smokers among medical students, teaching them about the damages related to tobacco use, and how to help them quit smoking or tobacco use, emerged as important issues. Further studies to investigate these important issues, using a standardized method like GHPSS, are needed.

Reliability and validity of the persian version of the scoliosis research society-22r questionnaire.  

UK PubMed Central (United Kingdom)

STUDY DESIGN: Cross-sectional validation study to investigate psychometric properties of adapted Persian version of the Scoliosis Research Society-22r (SRS-22r) questionnaire. OBJECTIVES.: To translate the SRS-22r into Persian and to evaluate the internal consistency, reliability, and validity of the Persian SRS-22r. SUMMARY OF BACKGROUND DATA: The SRS-22r has not been translated and validated for Persian-speaking patients with idiopathic scoliosis. This was to provide a validated instrument to measure health-related quality of life in patients with idiopathic scoliosis in Iran. METHODS: The translation and cultural adaptation of the original questionnaire were carried out in accordance with the published guidelines. About 84 patients with adolescent idiopathic scoliosis were participated in the study. The Short Form Health Survey (SF-36) was used to test convergent validity of the Persian SRS-22r. RESULTS: Moderate to high correlations were found between the SRS-22r domains and SF-36 subscales. The correlations ranged from 0.54 to 0.67 (function/activity domain), 0.48 to 0.74 (pain domain), 0.45 to 0.55 (self image domain), 0.66 to 0.85 (mental health domain), and 0.35 to 0.55 (satisfaction domain) (P < 0.01). One-way analysis of variance showed that the Persian questionnaire successfully discriminated between patients undergoing observation, brace, and surgical treatments (P < 0.05). Cronbach alpha coefficient for the Persian SRS-22r domains ranged from 0.68 to 0.78. The Persian SRS-22rdomains showed satisfactory test-retest reliability with Intraclass Correlation Coefficient ranged from 0.79 to 0.87 (P < 0.01). CONCLUSION: The Persian version of the SRS-22r has satisfactory reliability, convergent validity, and discriminant validity to measure health-related quality of life in adolescent patients with scoliosis in Iran. It is simple and easy to use and now can be applied in clinical settings and future outcome studies in Iran.

[Practical aspects for minimizing errors in the cross-cultural adaptation and validation of quality of life questionnaires].  

UK PubMed Central (United Kingdom)

BACKGROUND: The development and validation of questionnaires for evaluating quality of life (QoL) has become an important area of research. However, there is a proliferation of non-validated measuring instruments in the health setting that do not contribute to advances in scientific knowledge. AIMS: To present, through the analysis of available validated questionnaires, a checklist of the practical aspects of how to carry out the cross-cultural adaptation of QoL questionnaires (generic, or disease-specific) so that no step is overlooked in the evaluation process, and thus help prevent the elaboration of insufficient or incomplete validations. METHODS: We have consulted basic textbooks and Pubmed databases using the following keywords quality of life, questionnaires, and gastroenterology, confined to «validation studies» in English, Spanish, and Portuguese, and with no time limit, for the purpose of analyzing the translation and validation of the questionnaires available through the Mapi Institute and PROQOLID websites. RESULTS: A checklist is presented to aid in the planning and carrying out of the cross-cultural adaptation of QoL questionnaires, in conjunction with a glossary of key terms in the area of knowledge. The acronym DSTAC was used, which refers to each of the 5 stages involved in the recommended procedure. In addition, we provide a table of the QoL instruments that have been validated into Spanish. CONCLUSIONS: This article provides information on how to adapt QoL questionnaires from a cross-cultural perspective, as well as to minimize common errors.

Identification of adults with symptoms suggestive of obstructive airways disease: Validation of a postal respiratory questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Two simples scoring systems for a self-completed postal respiratory questionnaire were developed to identify adults who may have obstructive airways disease. The objective of this study was to validate these scoring systems. Method A two-stage design was used. All adults in two practice populations were sent the questionnaire and a stratified random sample of respondents was selected to undergo full clinical evaluation. Three respiratory physicians reviewed the results of each evaluation. A majority decision was reached as to whether the subject merited a trial of obstructive airways disease medication. This clinical decision was compared with two scoring systems based on the questionnaire in order to determine their positive predictive value, sensitivity and specificity. Results The PPV (positive predictive value) of the first scoring system was 75.1% (95% CI 68.6–82.3), whilst that of the second system was 82.3% (95% CI 75.9–89.2). The more stringent second system had the greater specificity, 97.1% (95% CI 96.0–98.2) versus 95.3% (95% CI 94.0–96.7), but poorer sensitivity 46.9% (95% CI 33.0–66.8) versus 50.3% (95% CI 35.3–71.6). Conclusion This scoring system based on the number of symptoms/risk factors reported via a postal questionnaire could be used to identify adults who would benefit from a trial of treatment for obstructive airways disease.

Validation of the Intestinal Part of the Prostate Cancer Questionnaire 'QUFW94': Psychometric Properties, Responsiveness, and Content Validity  

International Nuclear Information System (INIS)

Purpose: Several treatment options are available for patients with prostate cancer. Applicable and valid self-assessment instruments for assessing health-related quality of life (HRQOL) are of paramount importance. The aim of this study was to explore the validity and responsiveness of the intestinal part of the prostate cancer-specific questionnaire QUFW94. Methods and Materials: The content of the intestinal part of QUFW94 was examined by evaluation of experienced clinicians and reviewing the literature. The psychometric properties and responsiveness were assessed by analyzing HRQOL data from the randomized study Scandinavian Prostate Cancer Group 7 (SPCG)/Swedish Association for Urological Oncology 3 (SFUO). Subscales were constructed by means of exploratory factor analyses. Internal consistency was assessed by Cronbach's alpha. Responsiveness was investigated by comparing baseline scores with the 4-year posttreatment follow-up. Results: The content validity was found acceptable, but some amendments were proposed. The factor analyses revealed two symptom scales. The first scale comprised five items regarding general stool problems, frequency, incontinence, need to plan toilet visits, and daily activity. Cronbach's alpha at 0.83 indicated acceptable homogeneity. The second scale was less consistent with a Cronbach's alpha at 0.55. The overall responsiveness was found to be very satisfactory. Conclusion: Two scales were identified in the bowel dimension of the QUFW94; the first one had good internal consistency. The responsiveness was excellent, and some modifications are suggested to strengthen the content validity.

Elaboration and validation of a questionnaire assessing patient expectations about management of knee osteoarthritis by their physicians: the Knee Osteoarthritis Expectations Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVES: To develop a questionnaire assessing the expectations of patients regarding management of osteoarthritis (OA of the knee. METHODS: A detailed document reporting on a qualitative analysis of interviews of patients with knee OA was sent to experts and a Delphi procedure was adopted for item generation. Eighty physicians (64 general practitioners, 16 rheumatologists) recruited 566 patients with knee OA to test the provisional questionnaire. Items were reduced according to their metric properties and exploratory factor analysis. The reliability of the questionnaire was tested by the Cronbach ? coefficient. Construct validity was tested by divergent validity and confirmatory factor analysis. Test-retest reliability was assessed by the intraclass correlation coefficient (ICC) and the Bland-Altman technique. RESULTS: Sixty items were extracted from analysis of the interview data. The experts needed three Delphi rounds to obtain consensus on a 33-item provisional questionnaire. The item reduction process resulted in an 18-item questionnaire. Exploratory factor analysis extracted three main factors: factor 1 represented expectations for education, factor 2 expectations for information on technical and human support, and factor 3 expectations for physician empathy. The Cronbach ? coefficient was 0.91 (95% CI 0.89 to 0.92). Expected divergent validity was observed. Confirmation factor analyses confirmed higher intra-factor than inter-factor correlations. Test-retest reliability was good with an ICC of 0.79, and Bland-Altman analysis did not reveal a systematic trend. CONCLUSIONS: A new 18-item questionnaire assessing patient expectations of management of knee OA by their physicians is proposed. The questionnaire has good content and construct validity.

Peanut Allergen Threshold Study (PATS): validation of eliciting doses using a novel single-dose challenge protocol.  

UK PubMed Central (United Kingdom)

BACKGROUND: The eliciting dose (ED) for a peanut allergic reaction in 5% of the peanut allergic population, the ED05, is 1.5 mg of peanut protein. This ED05 was derived from oral food challenges (OFC) that use graded, incremental doses administered at fixed time intervals. Individual patients' threshold doses were used to generate population dose-distribution curves using probability distributions from which the ED05 was then determined. It is important to clinically validate that this dose is predictive of the allergenic response in a further unselected group of peanut-allergic individuals.Methods/Aims: This is a multi-centre study involving three national level referral and teaching centres. (Cork University Hospital, Ireland, Royal Children's Hospital Melbourne, Australia and Massachusetts General Hospital, Boston, U.S.A.) The study is now in process and will continue to run until all centres have recruited 125 participates in each respective centre.A total of 375 participants, aged 1--18 years will be recruited during routine Allergy appointments in the centres. The aim is to assess the precision of the predicted ED05 using a single dose (6 mg peanut = 1.5 mg of peanut protein) in the form of a cookie. Validated Food Allergy related Quality of Life Questionnaires-(FAQLQ) will be self-administered prior to OFC and 1 month after challenge to assess the impact of a single dose OFC on FAQL. Serological and cell based in vitro studies will be performed. CONCLUSION: The validation of the ED05 threshold for allergic reactions in peanut allergic subjects has potential value for public health measures. The single dose OFC, based upon the statistical dose-distribution analysis of past challenge trials, promises an efficient approach to identify the most highly sensitive patients within any given food-allergic population.

[Validation of the new German translation version of the "Short Inflammatory Bowel Disease Questionnaire" (SIBDQ)  

UK PubMed Central (United Kingdom)

In the face of a hardly predictable course of illness--potentially effecting a severe diminution of daily activities--the quality of life (QOL) represents a chief outcome measure in the treatment of inflammatory bowel diseases (IBD). For the German-speaking area an economical disease-specific instrument measuring QOL has been missing, so far. Therefore, we translated and adapted the recently validated "Short Inflammatory Bowel Disease Questionnaire" SIBDQ (11). Bowel symptoms, systemic symptoms, moods, and social activities are represented by a total of 10 items. Along with this questionnaire 7 accepted instruments assessing QOL-components were administered to 125 outpatients (54 ulcerative colitis, 71 Crohn's disease) and 51 healthy controls. The psychometric properties are good. Consistency is alpha = .84, thereby slightly surpassing the Anglo-American SIBDQ (alpha = .78). Retest-reliability after 26 weeks is r = .60. Systematic covariations with accepted QOL-instruments give evidence for its convergent and discriminatory validity. Differences between groups (high vs. low inflammatory activity vs. healthy controls) substantiate its sensitivity. Thus, the German adaptation of the accepted SIBDQ supplies an economic, reliable, and valid instrument that proved able to assess clinically relevant differences in QOL in patients with IBD. We suggest that it should be used by its overall score rather than its subscales. The instrument is appropriate to be used in therapy outcome and evaluation studies. It allows international comparison.

The Orthostatic Hypotension Questionnaire (OHQ): validation of a novel symptom assessment scale.  

UK PubMed Central (United Kingdom)

BACKGROUND: There is no widely accepted validated scale to assess the comprehensive symptom burden and severity of neurogenic orthostatic hypotension (NOH). The Orthostatic Hypotension Questionnaire (OHQ) was developed, with two components: the six-item symptoms assessment scale and a four-item daily activity scale to assess the burden of symptoms. Validation analyses were then performed on the two scales and a composite score of the OHQ. METHODS: The validation analyses of the OHQ were performed using data from patients with NOH participating in a phase IV, double blind, randomized, cross over, placebo-controlled trial of the alpha agonist midodrine. Convergent validity was assessed by correlating OHQ scores with clinician global impression scores of severity as well as with generic health questionnaire scores. Test-retest reliability was evaluated using intraclass correlation coefficients at baseline and crossover in a subgroup of patients who reported no change in symptoms across visits on a patient global impression scores of change. Responsiveness was examined by determining whether worsening or improvement in the patients' underlying disease status produced an appropriate change in OHQ scores. RESULTS: Baseline data were collected in 137 enrolled patients, follow-up data were collected in 104 patients randomized to treatment arm. Analyses were conducted using all available data. The floor and ceiling effects were minimal. OHQ scores were highly correlated with other patient reported outcome measures, indicating excellent convergent validity. Test-retest reliability was good. OHQ scores could distinguish between patients with severe and patients with less severe symptoms and responded appropriately to midodrine, a pressor agent commonly used to treat NOH. CONCLUSION: These findings provide empirical evidence that the OHQ can accurately evaluate the severity of symptoms and the functional impact of NOH as well as assess the efficacy of treatment.

[Face validity of a French questionnaire to screen binge eating disorder in adolescents.  

UK PubMed Central (United Kingdom)

Binge eating disorder is often associated with obesity. It has many psychosocial and somatic consequences and affects obesity treatment outcome. Binge eating has been observed in very young populations. Studies have shown that complications associated with binge eating disorder can appear in children, even when all the criteria included in the definition of the disorder for adults are not met. Therefore, provisional criteria have been proposed to investigate binge eating disorder among children and adolescents. There is an urgent need to enhance the screening of binge eating disorder in the young population, first in order to document the disorder and second to allow for tailored treatment of these populations. Currently, there is no scale in French to detect this type of disorder among children or adolescents. The aim of this study was to develop a self-administered questionnaire in French, which could be used as a screening tool for binge eating disorder among adolescents. We have developed a self-administered questionnaire, based on a previous questionnaire and provisional criteria proposed in the English-speaking world. In the present study, we assessed how the target population understood the expressions used in the questionnaire and refined terminology according to the results. Nineteen adolescents aged 11-18 years (normal weight or with obesity) were interviewed about their understanding of the questionnaire, using a structured individual interview. After completing the questions on their own, because the goal was to end up with a self-administered tool, they were asked to explain their own understanding of each question and to reformulate the terms used. The results highlighted that some words or sentences were misunderstood by adolescents, and we developed more adequate formulations as a consequence. Some terms used in their figurative sense had to be modified. Respondents found it difficult to assess duration and frequency of their behavior and suggested changing the open-ended answers to categories. Over the course of answering the questionnaire, they tended to forget the context and related their answers to their general eating behavior. Therefore, the context (binging) was repeated in each question of the modified version. A self-administered questionnaire can be effective in detecting problematic eating behaviors among adolescents and is a good first step before a diagnosis clarification by a professional. Our results show the importance of development and evaluation with the target population. The discriminant validity of the questionnaire will be evaluated by comparison with an assessment by a professional in a further study.

Validation of the ABILHAND questionnaire as a measure of manual ability in patients with rheumatoid arthritis  

Science.gov (United States)

Objective: Hand and upper limb involvement is common in patients with rheumatoid arthritis (RA). However, its impact on manual activities of daily life has not been fully evaluated. A measure of manual ability was developed, through the Rasch measurement model, by adapting and validating the ABILHAND questionnaire, which measures the patient's perceived difficulty in performing everyday manual activities. Methods 112 patients with RA were evaluated. The following tests were performed: the ABILHAND questionnaire, the Health Assessment Questionnaire (HAQ), the Jamar grip and key pinch strength tests, the Box and Block dexterity test and the Purdue pegboard dexterity test. In total, 35 patients were reassessed to determine the test–retest reliability of the ABILHAND, and 6 patients were studied before and after therapy with tumour necrosis factor (TNF) blockers to address sensitivity to change. Results The Rasch refinement of the ABILHAND led to a selection of 27 items rated on a 3?point scale. The resulting ability scale was targeted to the ability of the patients. The item?difficulty hierarchy was stable across demographic and clinical subgroups and over time. Grip and key pinch strength and manual and digital dexterity on both hands were significantly, though moderately, correlated with the ABILHAND measures. Manual ability was also significantly related to the number of affected hands, disease duration, tender and swollen joint counts on upper limbs, disease activity and the HAQ. Sensitivity to change was demonstrated in patients treated with TNF blockers, commensurate with their clinical improvement. Conclusion The ABILHAND questionnaire is a clinically valid person?centred measure of manual ability that could be useful in longitudinal RA studies.

Validity and reliability testing: Urdu translated modified Response to Symptoms Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To determine validity and reliability of the Urdu translated, modified "Response to symptoms questionnaire" (RSQ) among acute coronary syndrome (ACS) patients in Karachi. STUDY DESIGN: A qualitative, tool validation study. PLACE AND DURATION OF STUDY: Two tertiary care hospitals in Karachi, the Aga Khan University Hospital, Karachi and the Karachi Institute of Heart Diseases, from December 2010 to April 2011. METHODOLOGY: After making certain modifications, the original tool in English was translated into Urdu. Next, five cardiology experts evaluated the tool for its content and face validity. Test retest and inter rater reliabilities were computed for the RSQ using 5% of the total sample size of the parent study. RESULTS: Sufficient conceptual and semantic equivalence was found between the Urdu and English versions of the modified RSQ. Content validity index was calculated to be 1 for both relevance and linguistic clarity. Test retest and inter rater reliabilities were calculated to be 95.9% and K = 0.97, respectively. CONCLUSION: The Urdu translated modified RSQ has sufficiently acceptable content validity, test retest and inter rater reliability; hence, it should be used by the researchers for the evaluation of factors associated with pre-hospital delay among Urdu speaking ACS patient populations.

Cross-Cultural Adaptation Validation and Standardization of Ages and Stages Questionnaire (ASQ) in Iranian Children  

Directory of Open Access Journals (Sweden)

Full Text Available Background: To provide the validated and standardized form of the Persian version of the Ages and Stages Questionnaires as an appropriate developmental screening tool for evaluation of Iranian children’s development.Methods: This was a cross- sectional study. Translation and back-translation, content validity determination, cultural and lingual modifications, pilot study on 100 parents and inter-rater reliability determinations were performed, respectively. The national and final stage was carried out 11000, 4-60 month- old children in selected cities throughout the country in order to determine the validity, standard deviation, reliability, sensitivity, specificity, and mean scores points of the test.Results: The reliability, determined by cronbach’s alpha ranged from 0.76 to 0.86 and the inter-rater reliability was 0.93. The validity determined by factor analysis was satisfactory. The mean scores of Iranian children were identified and compared with those of the normative sample as well as with three other populations of children. The developmental status of Iranian children was higher in the communication, problem-solving and personal-social domains, especially under the age of 24 months, after which their developmental status seems to deteriorate, especially in the motor domains.Conclusion: The Persian version of the ASQ has appropriate validity and reliability for screening developmental disorders in Iran.

Short form of the Changes in Outlook Questionnaire: Translation and validation of the Chinese version  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The Changes in Outlook Questionnaire (CiOQ) is a self-report instrument designed to measure both positive and negative changes following the experience of severely stressful events. Previous research has focused on the Western context. The aim of this study is to translate the short form of the measure (CiOQ-S) into simplified Chinese and examine its validity and reliability in a sample of Chinese earthquake survivors. Method The English language version of the 10-item CiOQ was translated into simplified Chinese and completed along with other measures in a sample of earthquake survivors (n?=?120). Statistical analyses were performed to explore the structure of the simplified Chinese version of CiOQ-S (CiOQ-SCS), its reliability and validity. Results Principal components analysis (PCA) was conducted to test the structure of the CiOQ-SCS. The reliability and convergent validity were also assessed. The CiOQ-SCS demonstrated a similar factor structure to the English version, high internal consistency and convergent validity with measures of posttraumatic stress symptoms, anxiety and depression, coping and social support. Conclusion The data are comparable to those reported for the original version of the instrument indicating that the CiOQ-SCS is a reliable and valid measure assessing positive and negative changes in the aftermath of adversity. However, the sampling method cannot permit us to know how representative our samples were of the earthquake survivor population.

Validation of the Comprehensive Feeding Practices Questionnaire with parents of 10-to-12-year-olds  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background There is a lack of validated instruments for quantifying feeding behavior among parents of older children and adolescents. The Comprehensive Feeding Practices Questionnaire (CFPQ) is a self-report measure to assess multiple parental feeding practices. The CFPQ is originally designed for use with parents of children ranging in age from about 2 to 8 years. It is previously validated with American and French parents of children within this age range. The aim of the present study was to adapt and test the validity of this measure with parents of older children (10-to-12-year-olds) in a Norwegian setting. Methods A sample of 963 parents of 10-to-12-year-olds completed a Norwegian, slightly adapted version of the CFPQ. Scale analyses were performed to test the validity of the instrument in our sample. Results Although a few problematic items and scales were revealed, scale analyses showed that the psychometric properties of the slightly adapted, Norwegian version of the CFPQ were surprisingly similar to those of the original CFPQ. Conclusions Our results indicated that the CFPQ, with some small modifications, is a valid tool for measuring multiple parental feeding practices with parents of 10-to12-year-olds.

The coping flexibility questionnaire: development and initial validation in patients with chronic rheumatic diseases.  

Science.gov (United States)

Coping flexibility may be beneficial for the adjustment in the context of a progressive and unpredictable course of chronic rheumatic diseases. The aim of this study was to develop and initially validate a self-report measure that assesses coping flexibility. Study participants were 147 outpatients with chronic rheumatic diseases (73% women, mean age 59 (range 20-79) years). Principal axis factoring analysis with oblique rotation was applied and internal consistency was determined. To investigate the initial validity of the coping flexibility questionnaire (COFLEX), hypothesised correlations with psychological and physical adjustment outcomes, pain, and coping strategies were examined. Factor analysis yielded a two-factor model of coping flexibility with acceptable internal consistency: versatility, the capability of switching between assimilative and accommodative coping strategies according to personal goals and situational demands (? = .88) and reflective coping, the capability of generating and considering coping options, and appraising the suitability of a coping strategy in a given situation (? = .70). Versatility was correlated with adaptive ways of coping and psychological adjustment, but not with physical adjustment and pain. Reflective coping was correlated with both adaptive and maladaptive ways of coping, but it was not correlated with adjustment outcomes. In conclusion, the current study suggests acceptable internal consistency of the COFLEX. Preliminary evidence of the validity of the versatility dimension is indicated, while the validity of reflective coping could not be firmly established. The associations of versatility with favourable adjustment to the disease warrant future confirmatory and validity research in larger samples of patients with chronic rheumatic diseases.

Assessment of sexuality following traumatic brain injury: validation of the brain injury questionnaire of sexuality.  

UK PubMed Central (United Kingdom)

BACKGROUND: The importance of effectively identifying and managing sexuality issues following acquired brain injury is being increasingly recognized within clinical and research domains. However, a tool specifically developed to measure sexuality following brain injury is yet to be validated. OBJECTIVES: In this study, the reliability and validity of the Brain Injury Questionnaire of Sexuality (BIQS) was evaluated. METHOD: Eight hundred and sixty-five people who had sustained traumatic brain injury participated in this study. All participants completed the BIQS, and a subsample also completed the Derogatis Interview for Sexual Functioning-Self-Report version (DISF-SR). RESULTS: Exploratory factor analysis supported a 3-subscale structure of the BIQS, which aligns with contemporary conceptual models of sexuality in chronic disease. All subscales of the BIQS demonstrated very good internal consistency. Convergent and divergent validity of all BIQS subscales was also demonstrated. CONCLUSIONS: Results from the study support the reliability and validity of the BIQS, which shows promise as a measurement tool for future traumatic brain injury sexuality research. Further validation work including evaluation for potential clinical applications is encouraged.

Reliability and validity of a Dutch version of the Leicester Cough Questionnaire  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Chronic cough is a common condition with a significant impact on quality of life. Currently, no health status measure specific for chronic cough exists in the Netherlands. Thus we developed a Dutch version of the Leicester Cough Questionnaire (LCQ) and tested its scaling and clinical properties. Methods The LCQ was adapted for Dutch conditions following a forward-backward translation procedure. All patients referred to our cough clinic between May 2004 and February 2005 completed five questionnaires, the LCQ, the modified Borg score for cough, the Short-Form 36 (SF-36), the Hospital Anxiety and Depression Scale (HADS) and the Global Rating of Change (GRC) upon presentation, after two weeks and after 6 months. Concurrent validation, internal consistency, repeatability and responsiveness were determined. Results For the concurrent validation the correlation coefficients (n = 152 patients) between the LCQ and the other outcome measures varied between 0.22 and 0.61. The internal consistency of the LCQ (n = 58) was high for each of the domains with a Crohnbach's alpha coefficient between 0.77 and 0.91. The two week repeatability of the LCQ in patients with no change in cough (n = 48) was high with intraclass correlation coefficients varying between 0.86 and 0.93. Patients who reported an improvement in cough (n = 140) after 6 months demonstrated significant improvement on each of the domains of the LCQ. Conclusion The Dutch version of the LCQ is a valid and reliable questionnaire to measure (changes of) health status in patients with chronic cough.

The validity and reliability of the Moroccan version of the Revised Fibromyalgia Impact Questionnaire.  

UK PubMed Central (United Kingdom)

The Revised Fibromyalgia Impact Questionnaire (FIQ-R) is an updated version of the FIQ attempts to address the limitations of the Fibromyalgia Impact Questionnaire (FIQ). As there is no Moroccan version of the FIQ-R available, we aimed to investigate the validity and reliability of a Moroccan translation of the FIQR in Moroccan fibromyalgia (FM) patients. After translating the FIQR into Moroccan, it was administered to 80 patients with FM. All of the patients filled out the questionnaire together with Arabic version of short form-36 (SF-36). The tender-point count was calculated from tender points identified by thumb palpation. Three days later, FM patients filled out the Moroccan FIQR at their second visit. The test-retest reliability of the Moroccan FIQR questions ranged from 0.72 to 0.87. The test and retest reliability of total FIQR score was 0.84. Cronbach's alpha was 0.91 for FIQR visit 1 (the first assessment) and 0.92 for FIQR visit 2 (the second assessment), indicating acceptable levels of internal consistency for both assessments. Significant correlations for construct validity were obtained between the Moroccan FIQ-R total and domain scores and the subscales of the SF-36 (FIQR total versus SF-36 physical component score and mental component score were r = -0.69, P < 0.01 and r = -0.56, P < 0.01, respectively). The Moroccan FIQ-R showed adequate reliability and validity. This instrument can be used in the clinical evaluation of Moroccan and Arabic-speaking patients with FM.

The reliability, validity, and preliminary responsiveness of the Eye Allergy Patient Impact Questionnaire (EAPIQ)  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The Eye Allergy Patient Impact Questionnaire (EAPIQ) was developed based on a pilot study conducted in the US and focus groups with eye allergy sufferers in Europe. The purpose of this study was to present the results of the psychometric validation of the EAPIQ. Methods One hundred forty six patients from two allergy clinics completed the EAPIQ twice over a two-week period during the fall and winter allergy seasons, along with concurrent measures of health status, work productivity, and utility. Construct validity, reliability (internal consistency and test-retest), concurrent, known-group, and clinical validities, and responsiveness of the EAPIQ were assessed. Known-group validity was assessed by comparing EAPIQ scale scores between patients grouped according to their self-rating of ocular allergy severity (no symptoms, very mild, mild, moderate, severe, very severe). Clinical validity was assessed by assessing differences in EAPIQ scores between groups of patients rated by their clinician as non-symptomatic, mild, moderate, and severe. Results and Discussion Results from the validation study suggested the deletion of 14 of 43 items (including embedded questions) that required patients to complete the percentage of time they were troubled by something (daily activity limitations/emotional troubles). These items yielded a significant amount of missing or inconsistent data (50%). The resulting factor analysis suggested four domains: symptoms, daily life impact, psychosocial impact, and treatment satisfaction. When included as separate scales, the symptom-bother and symptom-frequency scales were highly correlated (> 0.9). As a consequence, and due to superior discriminative validity, the symptom bother and frequency items were summed. All items met the tests for item convergent validity (item-scale correlation = 0.4). The success rate for item discriminant validity testing was 97% (item-scale correlation greater with own scale than with any other). The criterion for internal consistency reliability (alpha coefficient ? 0.70) was met for all EAPIQ scales (range 0.89–0.93), as was the criterion for test-retest reliability (intraclass correlation [ICC] ? 0.70). Largely moderate correlations between the scales of the EAPIQ and the mini Rhinoconjunctivitis Quality of Life Questionnaire (miniRQLQ) and low correlations with the Health Utilities Index 2/3 (HUI2/3) were indicative of satisfactory concurrent validity. The EAPIQ symptoms, Daily Life Impact, and Psychosocial Impact scales were able to distinguish between patients differing in eye allergy symptom severity, as rated by patients and clinicians, providing evidence of satisfactory known-group and clinical validities, respectively. Preliminary analyses indicated the EAPIQ Symptoms, Daily Life Impact, and Psychosocial Impact scales to be responsive to changes in eye allergies. Conclusion Following item reduction, construct validity, reliability, concurrent validity, known-group validity, and preliminary responsiveness were satisfactory for the EAPIQ in this population of ocular allergy patients.

The comprehensive alcohol expectancy questionnaire: confirmatory factor analysis, scale refinement, and further validation.  

UK PubMed Central (United Kingdom)

The Comprehensive Alcohol Expectancy Questionnaire (CAEQ; Demmel & Hagen, 2003a, 2003b) is a self-report measure designed to assess an individual's alcohol expectancies. In this study, we examined the CAEQ in a student sample (N= 932) and in a clinical sample of alcohol-dependent inpatients (N= 744). The Five-factor structure was confirmed by means of confirmatory factor analysis. Convergent validity of the revised CAEQ was supported by showing significant relationships to quantity and frequency of drinking. The results of this study suggest that the revised CAEQ appears to be a psychometrically sound tool for the assessment of alcohol expectancies among both students and alcohol-dependent inpatients.

A reanalysis of the self-appraisal questionnaire: psychometric properties and predictive validity.  

UK PubMed Central (United Kingdom)

This research reassessed the psychometric properties and predictive validity of the Self-Appraisal Questionnaire (SAQ) in response to published criticism of the authors' earlier work. The current research used a much longer recidivism tracking-period, a different measure of recidivism, a larger sample, and more advanced analytic techniques than the original. Examination of the SAQ's psychometric properties continued to indicate that three of the six recidivism prediction subscales exhibited substandard levels of reliability and four of these subscales were not unidimensional. Yet, in contrast to the author's earlier results, the current analyses found that SAQ total score modestly predicted reconviction.

[Factorial validation of the alcohol expectancy questionnaire (AEQ-III), in adults living in Bucaramanga, Colombia].  

UK PubMed Central (United Kingdom)

BACKGROUND: Alcohol consumption is associated to expectancies of global positive behavioral changes, improvement in sexual performance and a higher level assertiveness. These issues are evaluated by the Alcohol Expectancy Questionnaire (AEQ-III). AIM: To perform a factorial validation of the Alcohol Expectancy Questionnaire (AEQ-III). MATERIALS AND METHODS: The questionnaire was applied to a representative sample of 601 subjects aged 18 to 60 years (334 males). These subjects also answered a socioeconomic questionnaire. The significant variables of the questionnaire were selected using an exploratory factorial analysis. Based on the selected variables, the verification was performed using multiple models of structural equations. Four factors, namely decrease in physical tension, decrease in psychological tension, increase in expressivity and sexuality and inhibition and feelings of power, were identified as significant. RESULTS: The factorial solution explains 59% of the variance. All the factors are conceptually and statistically consistent, with a Cronbach alpha ranging between 0.75 and 0.83. The global internal consistency was of 0.85. Pearson correlation coefficient among factors ranged between 0.45 and 0.74. There was a significant difference among socioeconomic levels for the factors lack of inhibition and feelings of power and decrease of psychological tension. Goodness of fit statistics and parsimony were high, ranging from 0.80 to 0.93. CONCLUSIONS: The expectancy decrease of physical tension and decrease of psychological tension are a part of individual behavior and could predict problem drinking. The factors increase of expressiveness and sexuality and lack of inhibition and feelings of power, are more associated to group behaviors.

A systematic review of reliability and objective criterion-related validity of physical activity questionnaires  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Physical inactivity is one of the four leading risk factors for global mortality. Accurate measurement of physical activity (PA) and in particular by physical activity questionnaires (PAQs) remains a challenge. The aim of this paper is to provide an updated systematic review of the reliability and validity characteristics of existing and more recently developed PAQs and to quantitatively compare the performance between existing and newly developed PAQs. A literature search of electronic databases was performed for studies assessing reliability and validity data of PAQs using an objective criterion measurement of PA between January 1997 and December 2011. Articles meeting the inclusion criteria were screened and data were extracted to provide a systematic overview of measurement properties. Due to differences in reported outcomes and criterion methods a quantitative meta-analysis was not possible. In total, 31 studies testing 34 newly developed PAQs, and 65 studies examining 96 existing PAQs were included. Very few PAQs showed good results on both reliability and validity. Median reliability correlation coefficients were 0.62–0.71 for existing, and 0.74–0.76 for new PAQs. Median validity coefficients ranged from 0.30–0.39 for existing, and from 0.25–0.41 for new PAQs. Although the majority of PAQs appear to have acceptable reliability, the validity is moderate at best. Newly developed PAQs do not appear to perform substantially better than existing PAQs in terms of reliability and validity. Future PAQ studies should include measures of absolute validity and the error structure of the instrument.

Validity of the international physical activity questionnaire and the Singapore prospective study program physical activity questionnaire in a multiethnic urban Asian population  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Physical activity patterns of a population remain mostly assessed by the questionnaires. However, few physical activity questionnaires have been validated in Asian populations. We previously utilized a combination of different questionnaires to assess leisure time, transportation, occupational and household physical activity in the Singapore Prospective Study Program (SP2). The International Physical Activity Questionnaire (IPAQ) has been developed for a similar purpose. In this study, we compared estimates from these two questionnaires with an objective measure of physical activity in a multi-ethnic Asian population. Methods Physical activity was measured in 152 Chinese, Malay and Asian Indian adults using an accelerometer over five consecutive days, including a weekend. Participants completed both the physical activity questionnaire in SP2 (SP2PAQ) and IPAQ long form. 43subjects underwent a second set of measurements on average 6 months later to assess reproducibility of the questionnaires and the accelerometer measurements. Spearman correlations were used to evaluate validity and reproducibility and correlations for validity were corrected for within-person variation of accelerometer measurements. Agreement between the questionnaires and the accelerometer measurements was also evaluated using Bland Altman plots. Results The corrected correlation with accelerometer estimates of energy expenditure from physical activity was better for the SP2PAQ (vigorous activity: r = 0.73; moderate activity: r = 0.27) than for the IPAQ (vigorous activity: r = 0.31; moderate activity: r = 0.15). For moderate activity, the corrected correlation between SP2PAQ and the accelerometer was higher for Chinese (r = 0.38) and Malays (r = 0.57) than for Indians (r = -0.09). Both questionnaires overestimated energy expenditure from physical activity to a greater extent at higher levels of physical activity than at lower levels of physical activity. The reproducibility for moderate activity (accelerometer: r = 0.68; IPAQ: r = 0.58; SP2PAQ: r = 0.55) and vigorous activity (accelerometer: 0.52; IPAQ: r = 0.38; SP2PAQ: r = 0.75) was moderate to high for all instruments. Conclusion The agreement between IPAQ and accelerometer measurements of energy expenditure from physical activity was poor in our Asian study population. The SP2PAQ showed good validity and reproducibility for vigorous activity, but performed less well for moderate activity particularly in Indians. Further effort is needed to develop questionnaires that better capture moderate activity in Asian populations.

Reliability and validity of the Japanese Migraine Disability Assessment (MIDAS) Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: This study was designed to assess the test-retest reliability, internal consistency, and validity of a Japanese translation of the Migraine Disability Assessment (MIDAS) Questionnaire in a sample of Japanese patients with headache. BACKGROUND: Previous studies have demonstrated that the English-language version of the MIDAS Questionnaire is a reliable and valid instrument for the assessment of migraine-related disability. Any translations of the MIDAS Questionnaire must also be assessed for reliability and validity. METHODS: Study participants were recruited from the patient population attending either the Neurology Department of Kitasato University or an affiliated clinic. Participants were eligible for study entry if they had 6 or more primary headaches per year. For reliability testing, participants completed the MIDAS Questionnaire on 2 occasions, exactly 2 weeks apart. To assess validity, patients were also invited to participate in a 90-day daily diary study. Composite measures from the 90-day diaries were compared to equivalent MIDAS measures (ie, 5 questions on headache-related disability and 1 question each on average pain intensity and headache frequency in the last 3 months) and to the total MIDAS score obtained from a third MIDAS Questionnaire completed at the end of this 90-day period. RESULTS: One hundred one patients between the ages of 21 and 77 years were recruited (81 women and 20 men). Ninety-nine patients (80 women and 19 men) participated in the diary study. At baseline, 46.5% of patients were MIDAS grade I or II (minimal, mild, or infrequent disability), 22.2% were MIDAS grade III (moderate disability), and 31.3% were MIDAS grade IV (severe disability). Test-retest Spearman correlations for the 5 disability questions and the questions on average pain intensity and headache frequency ranged from 0.59 to 0.80 (P<.0001). The test-retest Spearman correlation coefficient for the total MIDAS score was 0.83 (P<.0001). The degree to which individual MIDAS questions correlated with the diary-based measures ranged from 0.36 to 0.88. The correlation between the total MIDAS score and the equivalent diary-based measure was 0.66. In general, the mean and median values for the MIDAS items and total MIDAS score were similar to the means and medians for the diary-based measures. However, the mean MIDAS scores for the number of days on which headache was experienced and the number of missed workdays were significantly different compared to the diary-based estimates for these items (P<.05). In addition, the mean MIDAS score for the number of days of missed housework was significantly higher than the corresponding diary-based estimate (P<.01). CONCLUSIONS: The results from this study show that the Japanese translation of the MIDAS Questionnaire is comparable with the English-language version in terms of reliability and validity.

Using Rasch measurement to validate the Big Five factor marker questionnaire for a Japanese university population.  

UK PubMed Central (United Kingdom)

In recent years, psychological studies have increasingly come to support the so-called "Big Five" or "Five-factor Model" (FFM) of human personality. However, the vast majority of research in this field has been undertaken in Western contexts, thus raising the question of how applicable the Big Five is to Asian populations. Moreover, nearly all research into the Big Five has relied on traditional techniques of statistical analysis (e.g., factor analysis, correlation) to validate their results, despite the limitations of such methods. This study examined instrument validation of a widely-used Big Five instrument (the Factor Markers questionnaire) given to a Japanese population (n = 283) by using the Rasch rating scale model (Andrich, 1978). Rasch principal components analysis of the item residuals indicated the possible existence of additional factors within the Intellect/Imagination and Agreeableness factors, as well as additional item fit problems within each hypothesized construct.

Science.gov (United States)

This study was performed to evaluate the validity of the food frequency questionnaire (FFQ), which is being used at the Samsung Medical Center. In total, 305 (190 males and 115 females) participants consented and completed the 3-day diet records and FFQ. Age, gender and energy-adjusted and de-attenuated correlations ranged from 0.317 (polyunsaturated fatty acid) to 0.748 (carbohydrate) with a median value of 0.550. The weighted kappa value ranged from 0.18 (vitamin A) to 0.57 (carbohydrate) with a median value of 0.36. More than 75% of the subjects were classified into the same or adjacent quartiles. The FFQ had reasonably good validity compared with that of another study. Therefore, our FFQ is considered a proper method to assess nutrient intake in healthy Korean adults. PMID:23198024

Reliability and validity of the Chinese Version of the Mood Disorder Questionnaire.  

UK PubMed Central (United Kingdom)

The purpose of this study was to examine the reliability, validity, sensitivity, and specificity of the Chinese Version of the Mood Disorder Questionnaire (MDQ-C). A total of 170 patients were administered the Mini International Neuropsychological Interview and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision as criterion standard by on-site psychiatrists. The Cronbach's alpha, test-retest reliability, and the content validity index of the MDQ-C were .83, .76, and .80, respectively. Factor analysis revealed that two factors, elevated mood overactivity and irritable behavior, explained 40.89% of the variance. On the basis of the sensitivity and specificity results, the optimal cutoff point was 6.

Reliability and validity of the Chinese Version of the Mood Disorder Questionnaire.  

Science.gov (United States)

The purpose of this study was to examine the reliability, validity, sensitivity, and specificity of the Chinese Version of the Mood Disorder Questionnaire (MDQ-C). A total of 170 patients were administered the Mini International Neuropsychological Interview and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision as criterion standard by on-site psychiatrists. The Cronbach's alpha, test-retest reliability, and the content validity index of the MDQ-C were .83, .76, and .80, respectively. Factor analysis revealed that two factors, elevated mood overactivity and irritable behavior, explained 40.89% of the variance. On the basis of the sensitivity and specificity results, the optimal cutoff point was 6. The MDQ-C is an effective short and comprehensive tool with robust psychometric properties for diagnosis of bipolar disorders, specifically for patients with bipolar I. PMID:21251602

Development and initial validation of the Impression Motivation in Sport Questionnaire-Team.  

UK PubMed Central (United Kingdom)

Impression motivation is an important individual difference variable that has been under-researched in sport psychology, partly due to having no appropriate measure. This study was conducted to design a measure of impression motivation in team-sport athletes. Construct validity checks decreased the initial pool of items, factor analysis (n = 310) revealed the structure of the newly developed scale, and exploratory structural equation modeling procedures (n = 406) resulted in a modified scale that retained theoretical integrity and psychometric parsimony. This process produced a 15-item, 4-factor model; the Impression Motivation in Sport Questionnaire-Team (IMSQ-T) is forwarded as a valid measure of the respondent's dispositional strength of motivation to use self-presentation in striving for four distinct interpersonal objectives: self-development, social identity development, avoidance of negative outcomes, and avoidance of damaging impressions. The availability of this measure has contributed to theoretical development, will facilitate research, and offers a tool for use in applied settings.

German translation, cross-cultural adaptation and validation of the whiplash disability questionnaire.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Australian Whiplash Disability Questionnaire (WDQ) was cross-culturally translated, adapted, and tested for validity to be used in German-speaking patients. The self-administered questionnaire evaluates actual pain intensity, problems in personal care, role performance, sleep disturbances, tiredness, social and leisure activities, emotional and concentration impairments with 13 questions rated on an 11-point rating scale from zero to ten. METHODS: In a first part, the Australian-based WDQ was forward and backward translated. In a consensus conference with all translators and health care professionals, who were experts in the treatment of patients with a whiplash associated disorder (WAD), formulations were refined. Original authors were contacted for clarification and approval of the forward-backward translated version. The German version (WDQ-G) was evaluated for comprehensiveness and clarity in a pre-study patient survey by a random sample of German-speaking patients after WAD and four healthy twelve to thirteen year old teenagers. In a second part, the WDQ-G was evaluated in a patient validation study including patients affected by a WAD. Inpatients had to complete the WDQ-G, the North American Spine Society questionnaire (NASS cervical pain), and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) at entry in the rehabilitation centre. RESULTS: In the pre-study patient survey (response rate 31%) patients rated clarity for title 9.6 ± 0.9, instruction 9.3 ± 1.4 and questions 9.6 ± 0.7, and comprehensiveness for title 9.6 ± 0.7, instruction 9.3 ± 1.4 and questions 9.8 ± 0.4. Time needed to fill in was 13.7 ± 9.0 minutes. In total, 70 patients (47 females, age = 43.4 ± 12.5 years, time since injury: 1.5 ± 2.6 years) were included in the validation study. WDQ-G total score was 74.0 ± 21.3 points (range between 15 and 117 points). Time needed to fill in was 6.7 ± 3.4 minutes with data from 22 patients. Internal consistency was confirmed with Cronbachs's ? = 0.89. Concurrent validity showed a highly significant correlation with subscale pain and disability (NASS) at r = 0.74 and subscale pain (SF-36) at r = 0.71. CONCLUSIONS: The officially translated and adapted WDQ-G can be used in German-speaking patients affected by a WAD to evaluate patients' impairments in different domains. The WDQ-G is a self-administered outcome measure showing a high internal consistency and good concurrent validity.

Reliability and construct validity of self-report questionnaires for patients with pelvic girdle pain.  

UK PubMed Central (United Kingdom)

BACKGROUND: There is little evidence for the measurement properties of instruments commonly used for women with pelvic girdle pain. OBJECTIVE: The aim of this study was to examine the internal consistency, test-retest reliability, and construct validity of instruments used for women with pelvic girdle pain. DESIGN: This was a cross-sectional methodology study, including test-retest reliability assessment. METHODS: Women with pelvic girdle pain in pregnancy and after delivery participated in a postal survey that included the Pelvic Girdle Questionnaire (PGQ), Oswestry Disability Index (ODI), Disability Rating Index (DRI), Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and 8-item version of the Medical OUTCOMES: Study 36-Item Short-Form Health Survey questionnaire (SF-36). Test-retest reliability was assessed with a random subsample 1 week later. Internal consistency was assessed with the Cronbach alpha, and test-retest reliability was assessed with the intraclass correlation coefficient (ICC) and minimal detectable change (MDC). Construct validity based on hypotheses was assessed by correlation analysis. Discriminant validity was assessed with the area under the receiver operating characteristic curve. RESULTS: All participants responded to the main (N=87) and test-retest (n=42) surveys. Cronbach alpha values ranged from .88 to .94, and ICCs ranged from .78 to .94. The MDC at the individual level constituted about 7% to 14% of total scores for the 8-item version of the SF-36, ODI, and PGQ activity subscale; about 18% to 22% for the DRI, PGQ symptom subscale, and PCS; and about 25% for the FABQ. Hypotheses were mostly confirmed by correlations between the instruments. The PGQ was the only instrument that significantly discriminated participants who were pregnant from participants who were not pregnant as well as pain locations. LIMITATIONS: A comparison of responsiveness to change of the various instruments used in this study was not undertaken, but will be carried out in a future study. CONCLUSIONS: Self-report instruments for assessing health showed good internal consistency, test-retest reliability, and construct validity for women with pelvic girdle pain. The PGQ was the only instrument with satisfactory discriminant validity, thus, it is recommended for evaluating symptoms and disability in patients with pelvic girdle pain.

Assessing the safety attitudes questionnaire (SAQ), German language version in Swiss university hospitals - a validation study.  

UK PubMed Central (United Kingdom)

BACKGROUND: Improving patient safety has become a major focus of clinical care and research over the past two decades. An institution's patient safety climate represents an essential component of ensuring a safe environment and thereby can be vital to the prevention of adverse events. Covering six patient safety related factors, the Safety Attitudes Questionnaire (SAQ) is a validated and widely used instrument to measure the patient safety climate in clinical areas. The objective of this study was to assess the psychometric properties of the German language version of the SAQ. METHODS: A survey was carried out in two University Hospitals in Switzerland in autumn 2009 where the SAQ was distributed to a sample of 406 nurses and physicians in medical and surgical wards. Following the American Educational Research Association guidelines, we tested the questionnaire validity by levels of evidence: content validity, internal structure and relations to other variables. Confirmatory factor analysis was used to examine factor structure. Cronbach's alphas and inter-item correlations were calculated to examine internal consistency reliability. RESULTS: A total of 319 questionnaires were completed representing an overall response rate of 78.6%. For three items, the item content validity index was <0.75. Confirmatory factor analysis showed acceptable model fit (RMSEA = 0.045; CFI = 0.944) for the six-factor model. Additional exploratory factor analysis could not identify a better factor model. SAQ factor scores showed positive correlations with the Safety Organizing Scale (r = .56 - .72). The SAQ German version showed moderate to strong internal consistency reliability indices (Cronbach alpha = .65 - .83). CONCLUSIONS: The German language version of the SAQ demonstrated acceptable to good psychometric properties and therefore shows promise to be a sound instrument to measure patient safety climate in Swiss hospital wards. However, the low item content validity and large number of missing responses for several items suggest that improvements and adaptations in translation are required for select items, especially within the perception of management scale. Following these revisions, psychometric properties should reassessed in a randomly selected sample and hospitals and departments prior to use in Swiss hospital settings.

Validation of a semi-quantitative Food Frequency Questionnaire for Argentinean adults.  

UK PubMed Central (United Kingdom)

BACKGROUND: The Food Frequency Questionnaire (FFQ) is the most commonly used method for ranking individuals based on long term food intake in large epidemiological studies. The validation of an FFQ for specific populations is essential as food consumption is culture dependent. The aim of this study was to develop a Semi-quantitative Food Frequency Questionnaire (SFFQ) and evaluate its validity and reproducibility in estimating nutrient intake in urban and rural areas of Argentina. METHODS/PRINCIPAL FINDINGS: Overall, 256 participants in the Argentinean arm of the ongoing Prospective Urban and Rural Epidemiological study (PURE) were enrolled for development and validation of the SFFQ. One hundred individuals participated in the SFFQ development. The other 156 individuals completed the SFFQs on two occasions, four 24-hour Dietary Recalls (24DRs) in urban, and three 24DRs in rural areas during a one-year period. Correlation coefficients (r) and de-attenuated correlation coefficients between 24DRs and SFFQ were calculated for macro and micro-nutrients. The level of agreement between the two methods was evaluated using classification into same and extreme quartiles and the Bland-Altman method. The reproducibility of the SFFQ was assessed by Pearson correlation coefficients and Intra-class Correlation Coefficients (ICC). The SFFQ consists of 96 food items. In both urban and rural settings de-attenuated correlations exceeded 0.4 for most of the nutrients. The classification into the same and adjacent quartiles was more than 70% for urban and 60% for rural settings. The Pearson correlation between two SFFQs varied from 0.30-0.56 and 0.32-0.60 in urban and rural settings, respectively. CONCLUSION: Our results showed that this SFFQ had moderate relative validity and reproducibility for macro and micronutrients in relation to the comparison method and can be used to rank individuals based on habitual nutrient intake.

Validity and reliability of the Child Perceptions Questionnaires applied in Brazilian children  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The Child Perceptions Questionnaires (CPQ8–10 and CPQ11–14) are indicators of child oral health-related quality of life. The aim of this study was to assess the validity and reliability of the self-applied CPQ8–10 and CPQ11–14 in Brazilian children, after translations and cultural adaptations in the Brazilian Portuguese language. Methods Schoolchildren were recruited from general populations for pre-testing (n = 80), validity (n = 210), and test-retest reliability (n = 50) studies. They were also examined for dental caries, gingivitis, fluorosis, and malocclusion. Results Children with greater dental caries experience in primary dentition had higher impacts on CPQ domains. Girls had higher scores for CPQ8–10 domains than boys. Mean CPQ11–14 scores were highest for 11-year-old children and lowest for 14-year-old children. Construct validity was supported by significant associations between the CPQ8–10 and CPQ11–14 scores and the global rating of oral health (r = 0.38, r = 0.43) and overall well-being (r = 0.39, r = 0.60), respectively. The Cronbach's alpha was 0.95 for both questionnaires. The test-retest reliabilities of the overall CPQ8–10 and CPQ11–14 scores were both excellent (ICC = 0.96, ICC = 0.92). Conclusion The Brazilian Portuguese version of CPQ8–10 and CPQ11–14 was valuable and reliable for use in the Brazilian child population, although discriminant validity was sporadic due to the fact that impacts are mediated by others factors, such personal, social, and environmental variables.

Directory of Open Access Journals (Sweden)

Full Text Available Marie A Chisholm-Burns1,2, Steven R Erickson3, Christina A Spivey1, Rainer WG Gruessner2, Bruce Kaplan4 1Department of Pharmacy Practice and Science, University of Arizona College of Pharmacy, Tucson, AZ; 2Department of Surgery, University of Arizona College of Medicine, Tucson, AZ; 3Department of Clinical Sciences, University of Michigan College of Pharmacy, Ann Arbor, MI; 4Department of Medicine, The University of Arizona College of Medicine Tucson, AZ, USA Background: Valid instrumentation in the assessment of health-related quality of life (HQoL) in renal transplant recipients is critical to identifying particular nuances and determinants of HQoL in this population. Therefore, the validity of disease-specific instruments to measure HQoL in renal transplant recipients, such as the Kidney Transplant Questionnaire (KTQ), needs further investigation. The objective of this study was to assess the concurrent validity of the KTQ in adult US renal transplant recipients using the well established SF-12 Health Survey version 2 (SF-12v2) as the comparison instrument. Methods: One hundred and fourteen renal transplant recipients met the following inclusion criteria for this study, ie, were at least 21 years of age, more than two years post-transplant, and receiving immunosuppressant therapy. Subjects were asked to complete a series of HQoL instruments, ie, the KTQ and the SF-12v2 (physical component summary [PCS-12] and mental component summary [MCS-12]). Descriptive statistics were calculated, and correlational analyses were conducted to examine the concurrent validity of the HQoL instruments. Results: Among 100 participants (87.7% response rate), the majority of participants were male (52%), had deceased donor transplants (63%), and received Medicare benefits (84%). PCS-12 was positively correlated with three of five KTQ subscales (P < 0.05), ie, KTQ-physical (r = 0.43), KTQ-fatigue (r = 0.42), and KTQ-uncertainty/fear (r = 0.2). MCS-12 was positively correlated with all KTQ subscales (P < 0.01), ie, KTQ-physical (r = 0.26), KTQ-fatigue (r = 0.48), KTQ-uncertainty/fear (r = 0.33), KTQ-emotional (r = 0.47), and KTQ-appearance (r = 0.28). Conclusion: The findings support the concurrent validity of the KTQ in US renal transplant recipients. Future studies should continue exploring the validity of the KTQ, as well as its practical and research utility in HQoL measurement in the renal transplant population. Keywords: concurrent validity, kidney transplant questionnaire, quality of life, renal transplant recipients, SF-12 Health Survey

Measuring recovery: Validity of the "Recovery Process Inventory" and the "Recovery Attitudes Questionnaire".  

Science.gov (United States)

Considerable lack of publications and inconsistent results on construct validity make it difficult to choose an appropriate instrument to measure recovery. The aim of the present study was to evaluate additional psychometric aspects of two established measures of personal recovery with differing focusses. Bivariate associations of the recovery measures with personal, clinical and subjective factors were conducted as indicators of concurrent (convergent and divergent) validity. The scales were also tested concerning internal consistency. The sample comprised of 81 inpatients on an acute psychiatric ward (main diagnoses: 27% substance-related disorders, 27% schizophrenic disorders, 25% affective disorders, 10% neurotic or stress-related disorders, and 11% personality disorders). The "Recovery Attitudes Questionnaire (RAQ)" has to be reevaluated before further administration due to serious psychometric shortcomings concerning internal consistency and concurrent validity. The "Recovery Process Inventory (RPI)" total scale showed acceptable concurrent and within-scale validity and can be recommended in order to measure the personal recovery process for clinical and scientific purposes.

Turkish version of the Cornell Musculoskeletal Discomfort Questionnaire: cross-cultural adaptation and validation.  

UK PubMed Central (United Kingdom)

OBJECTIVE: This study documented the cross-cultural adaptation, validity, and reliability of the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) in the Turkish language. PARTICIPANTS: The participant group included 48 Turkish workers. METHODS: The cross-cultural adaptation included the translation, synthesis, back-translation, expert committee review and pretest stages. The adapted Turkish version of the CMDQ (T-CMDQ) was validated through self-administration of the tool and a Visual Analog Scale (VAS) among participants. RESULTS: The validity of the T-CMDQ was good; Kappa coefficients between the responses given on the VAS and on the T-CMDQ indicated substantial to almost perfect agreement (ranged between 0.62-0.92 across body parts), and Spearman rank correlation coefficients between the VAS scores and T-CMDQ severity scale responses were all significant (ranged between 0.46-0.83 across body parts). Test-retest reliability of the T-CMDQ was satisfactory; Kappa coefficients, which ranged between 0.56-0.97 across the three scales, indicated moderate to almost perfect agreement between test-retest responses across body parts. CONCLUSIONS: This study produced the T-CMDQ with good psychometric properties, presented the first formal validation of the CMDQ and provided useful insights on the cross-cultural adaptation process of a subjective data collection tool which was originally developed in English, into the Turkish language.

Validation of an Arabic version of the global Pelvic Floor Bother Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: To validate an Arabic version of the global Pelvic Floor Bother Questionnaire (PFBQ), a self-administered 9-item symptom assessment tool. METHODS: The translation-back translation method was used to create an Arabic version of the PFBQ. Clarity of terms and face validity were ensured by modifying the translated version according to comments from a focus group. The Arabic PFBQ was completed by 130 Lebanese women, who were allocated to affected (n=65) or control (n=65) groups on the basis of 2 verbally administered screening questions. Validity was assessed by comparing the PFBQ scores of the 2 groups. Test-retest reliability was evaluated in a subgroup of women who completed the PFBQ on 2 separate occasions; the intra-class correlation coefficient (ICC) for paired items was then calculated. RESULTS: Total PFBQ scores of the affected and control groups were significantly different (31.52 ± 16.80 vs 6.73 ± 7.50; P<0.001). Mean scores for individual PFBQ items were significantly different between the 2 groups, with the exception of dyspareunia. The ICC was above 0.7 for all individual items, thus confirming test-retest reliability. CONCLUSION: An Arabic version of the global PFBQ was developed and found to be both valid and reliable in the target population.

Korean version of the overactive bladder symptom score questionnaire: translation and linguistic validation.  

UK PubMed Central (United Kingdom)

PURPOSE: The overactive bladder symptom score (OABSS) consists of 4 questions regarding OAB symptoms. The aim of this study was to develop Korean version of the OABSS from the original Japanese version, with subsequent linguistic validation. METHODS: Between February and May 2008, the translation and linguistic validation process was performed as follows: a forward translation, reconciliation, backward translation, cognitive debriefing, and final proofreading. RESULTS: A forward translation from the original version of the OABSS to the Korean language was carried out by 2 native Korean speakers, who were also fluent in Japanese. Reconciliation was made after review of both translations by a panel consisting of both translators and one of the authors. Another bilingual translator who had never seen the original version of the OABSS carried out a translation of the reconciled version back into Japanese, and the original and backward-translated versions were subsequently compared. After discussion of all discrepancies between both versions by the panel, a second Korean version was produced. During cognitive debriefing, 5 outpatients with OAB reported that each question of the Korean version was significant and appropriate for their symptoms. However, 2 patients said that some parts of the questions or instructions were not clear or were not easy to understand. According to the cognitive debriefing, some words and phrases were revised into more understandable expressions. CONCLUSIONS: A Korean version of the OABSS was developed and linguistic validation was performed. Further studies are needed to assess the reproducibility and validity of the questionnaire in Korean populations.

Validity and reliability of a Fijian translation and adaptation of the Eating Disorder Examination Questionnaire.  

UK PubMed Central (United Kingdom)

OBJECTIVE: Assessment of disordered eating has uncertain validity across culturally diverse populations. This study evaluated Eating Disorder Examination Questionnaire (EDE-Q) performance in an ethnic Fijian study population. METHOD: The EDE-Q was translated, adapted, and administered to school-going Fijian adolescent females (N = 523). A subsample (n = 81) completed it again within approximately 1 week. We assessed feasibility, internal consistency, and test-retest reliability; evaluated construct validity through factor analysis and correlation with similar constructs; and examined the marginal utility of an additional question on traditional purgative use. RESULTS: Internal consistency reliability was adequate for the global scale and subscales (Cronbach's alpha = 0.66-0.91); retest reliability was adequate for both the languages (range of ICCs, 0.50-0.79, and of kappas, 0.46-0.81, excluding purging items). Construct validity was supported by significant correlations with measures of similar constructs. Factor analysis confirms multiple dimensions of eating disorder symptoms but suggests possible culture-specific variation in this population. The majority of respondents endorsing traditional purgative use (58%) did not endorse conventional EDE-Q items assessing purging. DISCUSSION: The EDE-Q is a valid measure of eating disorder pathology for ethnic Fijian adolescent females and measures a unitary underlying construct.

Reliability and Validity of Self-Reported Questionnaires Related to Adolescent Violence and Consequences, Thailand  

Directory of Open Access Journals (Sweden)

Full Text Available In Thailand physical violence among male adolescents is considered a significant public health issue, although there has been little published research into the aetiology and functions of violence in Thai youth. Research in this area has been hampered by a lack of psychometrically sound tools that have been validated to assess problem behaviours in Asian youth. The purpose of this paper is to provide validity and reliability data on an instrument to measure violence in Thai youth. In this study, reliability and validity data for a sample of adolescent Thai youth are reported for the Communities That Care Youth Survey (CTC-YS), a measure of risk and protective factors for violent behaviour, and the STAXI-II, a measure of angry experience and expression. The findings showed overall high internal consistency for both questionnaires, and there was evidence of construct validity. It is concluded that these measures are appropriate for use in research that seeks to investigate youth violence among adolescents in Thailand.

The validation of the Minnesota Job Satisfaction Questionnaire in selected organisations in South Africa  

Directory of Open Access Journals (Sweden)

Full Text Available The objectives of this study were to assess the construct equivalence of the Minnesota Job Satisfaction Questionnaire (MSQ), and to investigate the manifestation of job satisfaction at selected organisations in South Africa. A cross-sectional survey design with a random sample (N = 474) was used. The MSQ and a biographical questionnaire were administered. The results confirmed a two-factor model of job satisfaction, consisting of extrinsic job satisfaction and intrinsic job satisfaction. Exploratory factor analysis with target rotations conf rmed the construct equivalence of scales for the black and white groups. The results obtained from comparing job satisfaction levels of various demographic groups showed that practically significant differences existed between the job satisfaction of different age and race groups.How to cite this article:Buitendach, J.H., & Rothmann, S.

Assessing the validity of a physical activity questionnaire developed for parents of preschool children in Mexico.  

UK PubMed Central (United Kingdom)

To assess the validity of a questionnaire developed for parents of preschool children to know their physical activity (PA) status, we compared the questionnaire results with the measures of accelerometer for children's activities. Thirty-five preschoolers who wore the accelerometer for at least 10 hours daily on 3 weekdays and one weekend day were included in the analyses. Time spent in activities of varied intensity was calculated by applying 15-second ActiGraph count cutoffs (ACC). Parents' perceptions of their children's PA were associated with the percentage of vigorous and moderate physical activity recorded with ACC at r = 0.62 (p = 0.0001). An association was shown between the percentage of a child's time spent in vigorous physical activity, as reported by parents, with that measured by ACC at r = 0.53 (p = 0.001). Results of this study suggest that the designed questionnaire might be a useful tool for assessing children's activity while, additionally, it warrants further investigation on larger samples of children.

Psychometric properties of the Spanish validation of the Five Facets of Mindfulness Questionnaire (FFMQ)  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objectives: Mindfulness-based therapies have demonstrated effectiveness in many clinical contexts. Various therapies that train mindfulness skills have proliferated in recent years. There is increasing interest in mindfulness-based therapies and in incorporating instruments that measure mindfulness in order to understand its role in clinical and basic research. The Five Facets of Mindfulness Questionnaire (FFMQ) is a questionnaire for measuring mindfulness; it was derived from a factor analysis of five different questionnaires that measure a trait-like general tendency to be mindful in daily life. The objective of this study is to validate the FFMQ in a Spanish sample. Methods: The FFMQ was administered to a sample of 462 subjects ranging from 18 to 63 years (X = 27.9; SD = 9.75). The sample was composed by clinical (n = 146) and non-clinical (n = 226) subsamples. Results: The internal reliability of the scales ranged from acceptable to very good. Convergent analysis was conducted by computing Pearson's correlations, showing high correlations. The factorial structure is the same as that proposed by Baer et al. Conclusions: The FFMQ proved to be an effective instrument for measuring mindfulness in clinical and non-clinical Spanish samples.

The National Cancer Institute diet history questionnaire: validation of pyramid food servings.  

UK PubMed Central (United Kingdom)

The performance of the National Cancer Institute's food frequency questionnaire, the Diet History Questionnaire (DHQ), in estimating servings of 30 US Department of Agriculture Food Guide Pyramid food groups was evaluated in the Eating at America's Table Study (1997-1998), a nationally representative sample of men and women aged 20-79 years. Participants who completed four nonconsecutive, telephone-administered 24-hour dietary recalls (n = 1,301) were mailed a DHQ; 965 respondents completed both the 24-hour dietary recalls and the DHQ. The US Department of Agriculture's Pyramid Servings Database was used to estimate intakes of pyramid servings for both diet assessment tools. The correlation (rho) between DHQ-reported intake and true intake and the attenuation factor (lambda) were estimated using a measurement error model with repeat 24-hour dietary recalls as the reference instrument. Correlations for energy-adjusted pyramid servings of foods ranged from 0.43 (other starchy vegetables) to 0.84 (milk) among women and from 0.42 (eggs) to 0.80 (total dairy food) among men. The mean rho and lambda after energy adjustment were 0.62 and 0.60 for women and 0.63 and 0.66 for men, respectively. This food frequency questionnaire validation study of foods measured in pyramid servings allowed for a measure of food intake consistent with national dietary guidance.

Psychometric properties of the Spanish validation of the Five Facets of Mindfulness Questionnaire (FFMQ)  

Scientific Electronic Library Online (English)

Full Text Available Abstract in english Background and Objectives: Mindfulness-based therapies have demonstrated effectiveness in many clinical contexts. Various therapies that train mindfulness skills have proliferated in recent years. There is increasing interest in mindfulness-based therapies and in incorporating instruments that measure mindfulness in order to understand its role in clinical and basic research. The Five Facets of Mindfulness Questionnaire (FFMQ) is a questionnaire for measuring mindfulness; (more) it was derived from a factor analysis of five different questionnaires that measure a trait-like general tendency to be mindful in daily life. The objective of this study is to validate the FFMQ in a Spanish sample. Methods: The FFMQ was administered to a sample of 462 subjects ranging from 18 to 63 years (X = 27.9; SD = 9.75). The sample was composed by clinical (n = 146) and non-clinical (n = 226) subsamples. Results: The internal reliability of the scales ranged from acceptable to very good. Convergent analysis was conducted by computing Pearson's correlations, showing high correlations. The factorial structure is the same as that proposed by Baer et al. Conclusions: The FFMQ proved to be an effective instrument for measuring mindfulness in clinical and non-clinical Spanish samples.

Validity and reliability of the job content questionnaire in formal and informal jobs in Brazil  

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVES: This study evaluated the job content questionnaire (JCQ) in measuring work psychology aspects with respect to formal and informal jobs in Brazilian occupational groups. METHODS: A cross-sectional study was carried out in a random sample of 1311 ?15-year-old residents in the urban area of the city of Feira de Santana, Bahia, Brazil. The Portuguese JCQ version included the recommended 49-item of the original version. The JCQ performance evaluation included descriptive analysis, discriminant analysis, internal consistency, and construct validity. RESULTS: Averages of the JCQ scales were similar for the formal and informal workers, except for decision authority (formal job: c=31.9; informal jobs: c=34.5). The averages of the Portuguese JCQ scales did not differ substantially from those obtained in other European, North American, and Japanese studies, albeit they were slightly lower in the Brazilian case. In general, Cronbach’s alpha coefficients revealed performance similar to other large-sample studies, showing acceptable internal consistency. The coefficients were relatively similar for formal and informal jobs. Factor analysis revealed high consistency with the theoretical model. CONCLUSIONS: This is the first study to evaluate JCQ performance comparing formal and informal jobs in a developing country. The job content questionnaire presented a good global performance, and it did not differ substantially from those observed in other studies. These findings suggest that the job content questionnaire can be used in studies carried out in developing countries and in situations in which informal jobs are common.

Validation of the Farsi Version of the Schizotypal Personality Questionnaire in a Student Sample  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: This study was carried out to evaluate the psychometric properties of the Farsi version of Schizotypal Personality Questionnaire (SPQ) in a student sample. Method: 727 university students (442 males, 285 females) with a mean age of 23, who were selected using stepwise stratified method, and 15 patients with schizophrenia who were selected using convenience sampling, completed SPQ. The SPQ is a 74 items self-report questionnaire, which assesses nine DSM-III-R criteria for Schizotypal Personality Disorder. Data were analyzed by SPSS-16 and using Pearson’s correlation coefficient, independent t-test, multivariate analysis of variance, and exploratory factor analysis. Results: Cronbach’s alpha for the total questionnaire and its subscales were 0.90 and 0.59-0.82 respectively. SPQ accurately differentiated patients with schizophrenia from normal population. The exploratory factor analysis for SPQ confirmed the accuracy of three-factor structure introduced by Raine (cognitive-perceptual, interpersonal, and disorganized). Conclusion: SPQ is a valid and reliable instrument for assessing symptoms, dimensions, and factors of Schizotypal Personality Disorder.

Development and validation of a quality of life questionnaire for patients with colostomy or ileostomy  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Quality of life of stoma patients is increasingly being addressed in clinical trials. However, the instruments used in the majority of these studies have not been validated specifically for stoma patients. The aim of this paper is to describe the development and validation of a quality-of-life instrument, "Stoma-QOL", specifically for patients with colostomy or ileostomy. Methods Potential items were formulated in English on the basis of the results of a series of semi-structured interviews with 169 adult stoma patients. The process resulted in a preliminary 37-item version, which was translated into French, German, Spanish and Danish, and administered repeatedly to 182 patients with colostomy or ileostomy. A psychometric selection of items was performed through Rasch Analysis. The measurement properties of the final questionnaire version were subsequently tested. Results The 20 items in the final questionnaire covered four domains – sleep, sexual activity, relations to family and close friends, and social relations to other than family and close friends. These items were found to define a unidimensional variable according to Rasch specifications (Infit MNSQ 0.88 (p Conclusion Given the adequacy of the metric properties of the Stoma-QOL suggested by the psychometric analyses, this study confirms the suitability of the instrument in clinical practice and in clinical research.

Validity of the Chinese version Mood Disorder Questionnaire (MDQ) and the optimal cutoff screening bipolar disorders.  

Science.gov (United States)

To investigate the validity of the Chinese version of Mood Disorder Questionnaire (C-MDQ) in China. Patients with bipolar disorders (BP, N=284) and patients with unipolar depressive disorder (UP, N=134) were assessed with the C-MDQ. The Eigenvalues of the first two factors were 3.15 and 2.09, respectively. The Cronbach's alpha of the C-MDQ was 0.79. The frequency of positive responses of UP patients was significantly lower than those of BP patients for 12 items except the seventh item. A C-MDQ screening score of seven or more was the best cutoff between BP and UP. The C-MDQ could distinguish between bipolar II disorder (BP-II) and UP, and the best cutoff was five. A cutoff of five had a sensitivity of 0.80 and a specificity of 0.54 between BP and UP. This study demonstrated the good validity of C-MDQ in China. The best cutoff between BP-II and UP can be regarded as the optimal cutoff between BP and UP to improve the sensitivity of screening for BP-II. Five should be the optimal cutoff between the BP and UP when only the 13 items of the questionnaire are used in China. PMID:21402414

Clinical examinations to validate self-completion questionnaires: dermatitis in the UK printing industry.  

Science.gov (United States)

A self-completion questionnaire sent to 2600 Nottinghamshire members of the Graphical Paper and Media Union elicited a 62% response. Forty one per cent of respondents reported suffering a skin complaint at some time and 11% had a current skin problem on the hand. This paper reports the validation stage of the study. Samples of 45 'cases' of self-reported dermatitis and 60 'controls', who reported they had never suffered a skin complaint, were clinically examined. All 45 self-reported cases were clinically confirmed as dermatitis. Occupationally related irritant contact dermatitis (ICD) was diagnosed in 20 (44%); 26 (58%) complaints were thought to be induced or exacerbated by occupation. Of the controls, 21 (35%) were also diagnosed with a skin complaint, the majority being mild, with an occupational association in 17, the majority (15) being ICD. Sixteen ICD cases were patch tested resulting in positive reactions to colophony, neomycin, nickel and potassium dichromate (2 of each). Two cases of basal cell carcinoma on the face were also identified, of which the participants were unaware. Although there was no false positive self-reporting there was a considerable number of false negatives, demonstrating the importance of clinical validation of questionnaires relating to industrial skin disease. This study has highlighted the need for improvement in skin care provision in the printing industry. PMID:12225406

The two-track model of bereavement questionnaire (TTBQ): development and validation of a relational measure.  

UK PubMed Central (United Kingdom)

The Two-Track Model of Bereavement Questionnaire (TTBQ) was designed to assess response to loss over time. Respondents were 354 persons who completed the 70-item self-report questionnaire constructed in accordance with the Two-Track Model of Bereavement. Track I focuses on the bereaved's biopsychosocial functioning and Track II concerns the bereaved's ongoing relationship to the range of memories, images, thoughts, and feeling states associated with the deceased. Factor analysis identified 5 factors that accounted for 51% of the variance explained. In accord with the theoretical and clinical model, 3 factors were primarily associated with the relationship to the deceased (Track II): Active Relational Grieving, Close and Positive Relationship, and Conflictual Relationship; and 2 factors with aspects of functioning (Track I): General Biopsychosocial Functioning and Traumatic Perception of the Loss. Construct and concurrent validity were examined and were found satisfactory. Differences by kinship, cause of death, gender, and time elapsed were examined across the 5 factors, the total TTBQ, and the ITG. The new measure is shown to have both construct and concurrent validity. Discussions of the results and implications for the measurement of response to loss conclude the article.

Comparison of powder and aerosolized budesonide in perennial rhinitis: validation of rhinitis quality of life questionnaire.  

Science.gov (United States)

The aims of the study were to compare the efficacy and side effects of intranasal budesonide as a dry powder and as a freon propelled pressurized aerosol in the treatment of perennial rhinitis and to validate a perennial rhinitis quality of life questionnaire. The design was a single-blind, randomized, parallel group comparison of two active treatments over a 6-week period. Sixty adults with symptomatic perennial rhinitis, stratified for atopy, received 400 micrograms intranasal budesonide administered daily either as one inhalation/nostril/day of pure drug powder or two puffs/nostril/day of drug delivered by a freon propelled aerosol. Subjects kept daily symptom diaries and, at each clinic visit, rhinitis quality of life and adverse experiences were recorded. Fifty-eight subjects completed the study. During the 6 weeks, there were significant improvements in symptoms and quality of life in both treatment groups. The improvements tended to be slightly greater in the aerosol group but the differences did not reach significance. Most frequently reported adverse experiences were headache and nosebleed, which were equally distributed in the two groups. We conclude that budesonide taken 400 micrograms daily for 6 weeks was associated with improvements in perennial rhinitis with little evidence of any difference in efficacy or side effects between the powder and aerosol. The questionnaire is a valid instrument for assessing quality of life in perennial rhinitis clinical trials. PMID:8452318

Development and validation of a short questionnaire for estimating the intake of zinc.  

UK PubMed Central (United Kingdom)

Zinc is an essential nutrient required for numerous metabolic functions. The aim of the present study was to develop a zinc-specific food frequency questionnaire (FFQ) and to determine its relative validity. A 74-item FFQ was designed for the measurement of zinc intake. Food items were included in the FFQ if their zinc content was >0.5 mg/100 g, and the food item contributed >5% of the recommended dietary intake. Female subjects (n = 22) were recruited to complete the questionnaire in addition to maintaining a weighed food record for 7 days. Mean intake of zinc obtained from the weighed records (8.8 +/- 2.3 mg/day; mean +/- SD) was significantly lower than that obtained from the FFQ (10.5 +/- 3.1 mg/day; P < 0.01). Ranked zinc intakes obtained from the two instruments were significantly correlated (r (s) = 0.81, P < 0.001). Evaluation of progressively shortened versions of the FFQ, containing 23-61 food items and representing 60-90% of the contribution to total zinc intake, yielded correspondingly decreasing magnitudes of zinc intake, but the rank correlation with the weighed records was significant (P < 0.01). Rank correlations and analysis of plots from Bland-Altman analyses suggest that a shortened 37-item FFQ has comparable validity to the full FFQ. A shortened FFQ is likely to produce lower demands on the interviewer and/or respondent when assessing zinc intake.

Marijuana Craving Questionnaire: development and initial validation of a self-report instrument.  

UK PubMed Central (United Kingdom)

AIMS: To develop and validate a multi-dimensional questionnaire on marijuana craving. DESIGN AND MEASUREMENTS: Current marijuana smokers (n = 217) not seeking treatment completed a 47-item Marijuana Craving Questionnaire (MCQ) and forms assessing demographics, drug use history, marijuana quit attempts and current mood. FINDINGS: Exploratory and confirmatory factor analyses indicated that a four-factor solution best described the item structure. Factor subscales derived from the 17 items with significant loadings had respectable internal consistencies and were stable across settings and subgroups. The subscales exhibited low to moderate, positive intercorrelations and were significantly correlated with marijuana use history and a wide range of single-item measures of craving. CONCLUSIONS: Findings suggested that four specific constructs characterize craving for marijuana: (1) compulsivity, an inability to control marijuana use; (2) emotionality, use of marijuana in anticipation of relief from withdrawal or negative mood; (3) expectancy, anticipation of positive outcomes from smoking marijuana; and (4) purposefulness, intention and planning to use marijuana for positive outcomes. These data indicate that the MCQ is a valid and reliable instrument for assessing marijuana craving in individuals not seeking drug abuse treatment and that marijuana craving can be measured in the absence of withdrawal.

The Experience with Allergic Rhinitis Nasal Spray Questionnaire (EARNS-Q) was developed to measure subject experiences with and preferences for nasal sprays.Objective: To describe the psychometric validation of the EARNS-Q modules.Methods: An observational study was conducted with subjects aged 18–65 years with physician-diagnosed vasomotor, seasonal, and/or perennial allergic rhinitis who were using a prescription nasal spray. Subjects completed the experience module of the EARNS-Q and the Treatment Satisfaction Questionnaire with Medication (TSQM) at baseline and after 2 weeks. Further validation analyses were conducted in a 3-week, randomized, single-blind, crossover, multicenter clinical study in which subjects ?18 years of age with documented seasonal AR received flunisolide and beclomethasone and completed the EARNS-Q experience module on days 1 and 8, the EARNS-Q preference module on day 22, and the TSQM on days 8 and 22.Results: The observational and clinical studies were completed by 121 and 89 subjects, respectively. Both modules demonstrated acceptable reliability (? = 0.72 experience module; ? = 0.93 preference module global scores) and validity (intraclass correlation coefficient or ICC 0.64 to 0.82 test–retest validity). Correlations among the experience and preference modules were moderate (r = 0.39 to 0.79) and within internal consistency reliability estimates, indicating measurement of distinct constructs.Conclusion: The EARNS-Q is a patient-reported outcomes measure that enables reliable and valid measurement of subject experience with, and preference for, prescription intranasal corticosteroid sprays for allergic rhinitis.Keywords: EARNS-Q, allergic rhinitis, compliance, intranasal corticosteroid, patient preference, psychometric validation

Validation of the self regulation questionnaire as a measure of health in quality of life research  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Objectives Several epidemiological studies address psychosomatic 'self regulation' as a measure of quality of life aspects. However, although widely used in studies with a focus on complementary cancer treatment, and recognized to be associated with better survival of cancer patients, it is unclear what the 'self regulation' questionnaire exactly measures. Design and setting In a sample of 444 individuals (27% healthy, 33% cancer, 40% other internal diseases), we performed reliability and exploratory factor analyses, and correlated the 16-item instrument with external measures such as the Hospital Anxiety and Depression Scale, the Herdecke Quality of Life questionnaire, and autonomic regulation questionnaire. Results The 16-item pool had a very good internal consistency (Cronbach's alpha = 0.948) and satisfying/good (rrt = 0.796) test-retest reliability after 3 months. Exploratory factor analysis indicated 2 sub-constructs: (1) Ability to change behaviour in order to reach goals, and (2) Achieve satisfaction and well-being. Both sub-scales correlated well with quality of life aspects, particularly with Initiative Power/Interest, Social Interactions, Mental Balance, and negatively with anxiety and depression. Conclusions The Self Regulation Questionnaire (SRQ) was found to be a valid and reliable tool which measures unique psychosomatic abilities. Self regulation deals with competence and autonomy and can be regarded as a problem solving capacity in terms of an active adaptation to stressful situations to restore wellbeing. The tool is an interesting option to be used particularly in complementary medicine research with a focus on behavioural modification.
