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 Inve [...] ntory (BDI) in tinnitus patients. STUDY DESIGN: Prospective, cross-sectional. MATERIALS AND METHODS: Subjects were submitted to tonal audiometry, PM and MML for tinnitus. They 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.

The construct validity of the Career Resilience Questionnaire (Fourie & VanVuuren, 1998) was investigated by means of an oblique multiple groups factor analysis.The highest factor structure coefficients of several of the items did not coincide with the respective factors that the items were postulated to measure. In addition, the correlations among the factors cast doubt on the independence of some of the constructs.

Sidney Blatt, considering as being insufficient the categorical-symptomatic approach of depression, has worked out a theory of depression and psychopathology that integrates the contributions of psychoanalysis as well as cognitive and developmental psychology. Within a broad psychoanalytic framework, Blatt's formulation focus on the quality of interpersonal relationship, the nature of object representation and early life experiences. Personality development is viewed as the consequence of the interaction of 2 basic developmental tasks: the establishment of the capacity to form stable, enduring, mutually satisfying interpersonal relationships and the achievement of a differentiated, realistic, essentially positive identity. The relationship between these 2 developmental lines involves a complex dialectical process during which progress in each line is essential for progress in the other and which contributes to the development of both a sense of identity and the capacity for interpersonal relatedness. These developmental lines permit not only to define an during individual's primary personality configuration but also enable to identify cognitive structures that are inherent in various forms of psychopathology, including depression. Disruptions at different developmental stages create vulnerability to different subsequent psychological disturbances. Blatt characterised as anaclitic or dependent the axis concerned with interpersonal relationship and as introjective or self-critical the axis concerned with development of the sense of self and identity. Depressive Experience Questionnaire was developed by Blatt et al. to determine the validity of this model of psychopathology which emphazises continuities between normal and pathological forms of depression. The instrument was developed by Blatt et al. by assembling a pool of items describing experiences frequently reported by depressed individual. Sixty-six items were selected and administered to a large nonclinical sample (500 female and 160 male undergraduates). Principal component analysis within sex performed on the answers to DEQ confirmed his assumption in identifying two principal depressive dimensions. The first factor involved items that are primarily externally directed and refer to a disturbance of interpersonal relationships (anaclitism); the second factor consists of items that are more internally directed and reflect concerns about self-identity (self-criticism). A third factor emerged, assessing the good functioning of subject and confidence in his resources and capacities (efficacy). Scales derived from these factors have high internal consistency and substantial test-retest reliability. The solutions for men and women were highly congruent. Factor structure has been replicated in several nonclinical and clinical samples, supporting considerable evidence to the construct validity of the DEQ Dependency and Self-criticism scales. An adolescent form of DEQ (DEQ-A) has successively been developed. Factor analysis revealed three factors that were highly congruent in female and male students and with the three factors of the original DEQ. The reliability, internal consistency and validity of DEQ-A indicate that the DEQ-A closely parallels the DEQ, especially in the articulation of Dependency and Self-criticism as two factors in depression. These formulations and clinical observations about the importance of differentiating a depression focused on issues of self-criticism from issues of dependency are consistent with the formulations of others theorists which, from very different theoretical perspectives, posit 2 types of depression, one in which either perceived loss or rejection in social relationships is central and the other in which perceived failure in achievement, guilt or lack of control serves as the precipitant of depression. These 2 types of experiences have been characterized as dominant other and dominant goal , as anxiously attached and compulsively self-reliant and as sociotropic and autonomous . Our work presents the results of a validation study of b

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.

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.
This study tested the validity of four measures of dietary restraint: Dutch Eating Behavior Questionnaire, Eating Inventory (EI), Revised Restraint Scale (RS), and the Current Dieting Questionnaire. Dietary restraint has been implicated as a determinant of overeating and binge eating. Conflicting findings have been attributed to different methods for measuring dietary restraint. The validity of four self-report measures of dietary restraint and dieting behavior was tested using: 1) factor ana...

In the first research conducted on the sample of 1127 participants of both sexes, age 18 to 67, the results of the principal component analysis of the MPQ scales point to the existence of three higher-order dimensions, named General Adaptedness, Psychopathic Tendencies and Negative Emotionality. These dimensions correspond to the dimensions of the Eysenck’s PEN model to the greater extent than they achieve the assumed similarity with the dimensions of the Reinforcement Sensitivity Theory. In the second study conducted on the sample of 199 respondents of both sexes, age 18 to 59, the results of the joint principal component analysis of the MPQ and SPSRQ scales point to the existence of three higher order dimensions, which correspond to the Tellegen’s Positive Emotionality, Negative Emotionality, and Constraint. .

Full Text Available Primary care physicians face challenges in diagnosing and managing gastroesophageal reflux disease (GERD. The Reflux Disease Questionnaire (RDQ meets the standards of validity, reliability, and practicability. This paper reports on the validation of the Greek translation of the RDQ. RDQ is a condition specific instrument. For the validation of the questionnaire, the internal consistency of its items was established using the alpha coefficient of Chronbach. The reproducibility (test-retest reliability was measured by kappa correlation coefficient and the criterion of validity was calculated against the diagnosis of another questionnaire already translated and validated into Greek (IDGP using kappa correlation coefficient. A factor analysis was also performed. Greek RDQ showed a high overall internal consistency (alpha value: 0.91 for individual comparison. All 8 items regarding heartburn and regurgitation, GERD, had good reproducibility (Cohen’s ? 0.60-0.79, while the remaining 4 items about dyspepsia had a moderate reproducibility (Cohen’s ?=’ 0.40-0.59 The kappa coefficient for criterion validity for GERD was rather poor (0.20, 95% CI: 0.04, 0.36 and the overall agreement between the results of the RDQ questionnaire and those based on the IDGP questionnaire was 70.5%. Factor analysis indicated 3 factors with Eigenvalue over 1.0, and responsible for 76.91% of variance. Regurgitation items correlated more strongly with the third component but pain behind sternum and upper stomach pain correlated with the second component. The Greek version of RDQ seems to be a reliable and valid instrument following the pattern of the original questionnaire, and could be used in primary care research in Greece.
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 perspective of caring of comatose patient questionnaire had 32 items and 4 dimension and showed validity and reliability, but it need to test more and more to multiplication of its' validity and reliability.
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 ng 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
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.

The Leicester Cough Questionnaire (LCQ) is a self-administered questionnaire developed in England and validated for reliability. We developed a Korean translation of this questionnaire by applying a sequential forward and backward translation approach. The purpose of this study is to validate the Korean version of the LCQ (LCQ-K) in Korean patients with chronic cough. A multicenter prospective study was undertaken with 100 chronic cough patients who consented to participate in the study. The LCQ-K includes eight physical items, seven psychological items, and four social items. Visual analog scale (VAS) of cough, Borg Cough Scale (BCS), and Short Form-36 (SF-36) were used as external comparators. Participants included 52 women and 48 men with ages ranging from 18 years to 69 years. The concurrent validity comparing LCQ-K to VAS, BCS, and SF-36 yielded statistically significant Pearson correlation coefficients. The LCQ-K showed good reliability in three domains, with Cronbach's ? coefficients ranging from 0.84 to 0.87 (total: 0.91). Test-retest reliability was investigated with single measure intraclass correlation coefficients, which were found to be practically and statistically significant (p = 0.005). Responsiveness was validated by effective size ranging from 1.16 to 1.40 in each domain. LCQ-K is a reliable, valid, and responsive disease-specific questionnaire for assessing symptoms and quality of life of Korean patients with chronic cough. PMID:24906688

Full Text Available Abstract Background Precise measurements of activity at a population level are important for monitoring trends and evaluating health promotion strategies. Few studies have assessed the measurement of physical activity in developing countries. The aim of this study was to validate the MOSPA (Monica Optional Study of Physical Activity questionnaire which was developed for the WHO-Monitoring trends and determinants of cardiovasculr disease (MONICA study sites. Methods The MOSPA questionnaire assesses energy expendtiture (EE related to physical activity (employment, household work, transportation, and leisure time over a one year period. This questionnaire has been described in the manuscript as the long term (LT questionnaire. An adapted short term (ST 5 day questionnaire was developed to assess convergent validity. Questionnaire data were compared with physical activity EE estimates from a Caltrac accelerometer and with body composition measures (height, weight and bioelectrical impedance in 50 women from the Aga Khan University (AKU hospital antenatal clinics, Pakistan. Other forms of EE i.e. resting EE and thermic effect of food were not assessd in this study. Results Subjects were aged 26 ± 3.8 years and were 16.1 ± 6.7 weeks pregnant. Their average weight was 58.8 ± 10.7 Kg. The average EE/day assessed by the Caltrac accelerometer, was 224 kcal and by MOSPA LT questionnaire it was 404 kcal. The questionnaires and Caltrac data were reasonably well correlated: r = 0.51 and r = 0.60 (P Conclusion The MOSPA questionnaire is useful in assessing physical activity levels in a sedentary population over a one year period.

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 subscwith 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.
Study Objective: At least 15% of the full-time work force is shift workers. Working during the overnight hours, early morning start times, and variable or rotating schedules present a challenge to the circadian system, and these shifts are associated with adverse health and safety consequences. Shift work disorder (SWD), a primary (circadian rhythm) sleep disorder indicated by excessive daytime sleepiness and/or insomnia associated with a shiftwork schedule, is under-recognized by primary care physicians. We sought to develop and validate a questionnaire to screen for high risk of SWD in a shift working population. Design: Shift workers completed a 26-item questionnaire and were evaluated by a sleep specialist (physician) who diagnosed them as either positive or negative for SWD. The physician assessment of SWD was guided by a flow chart that operationalized the ICSD-2 criteria for SWD. Setting: 18 sleep clinics in the USA. Patients or Participants: 311 shift workers. Interventions: Not applicable. Measurements and Results: Responses to the items in the questionnaire were entered into a series of discrimination function analyses to determine the diagnostic value of the items and the fewest number of questions with the best predictive value. The function was then cross-validated. A final 4-item questionnaire has 89% positive predictive value and 62% negative predictive value (sensitivity = 0.74; specificity = 0.82). Conclusions: This Shiftwork Disorder Screening Questionnaire may be appropriate for use in primary care settings to aid in the diagnosis of SWD.

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.
Full Text Available Validity and Reliability of Agoraphobic Cognitions Questionnaire-Turkish Version Objective: The aim of this study is to investigate the validity and reliability of Agoraphobic Cognitions Questionnaire -Turkish Version (ACQ. Method: ACQ was administered to 92 patients with agoraphobia or panic disorder with agoraphobia. BSQ Turkish version completed by translation, back-translation and pilot assessment. Reliability of ACQ was analyzed by test-retest correlation, split-half technique, Cronbach’s alpha coefficient. Construct validity was evaluated by factor analysis after the Kaiser-Meyer-Olkin (KMO and Bartlett test had been performed. Principal component analysis and varimax rotation used for factor analysis. Results: 64% of patients evaluated in the study were female and 36% were male. Age interval was between 18 and 58, mean age was 31.5±10.4. The Cronbach’s alpha coefficient was 0.91. Analysis of test-retest evaluations revealed that there were statistically significant correlations ranging between 24% and 84% concerning questionnaire components. In analysis performed by split-half method reliability coefficients of half questionnaires were found as 0.77 and 0.91. Again Spearmen-Brown coefficient was found as 0.87 by the same analysis. To assess construct validity of ACQ, factor analysis was performed and two basic factors found. These two factors explained 57.6% of the total variance. (Factor 1: 34.6%, Factor 2: 23% Conclusion: Our findings support that ACQ-Turkish version had a satisfactory level of reliability and validity

So far no validated questionnaires are available to measure symptom and functional state in daily clinical practice. The aim of this study was to develop and validate the Clinical COPD Questionnaire (CCQ. Methods Qualitative research with patients and clinicians was performed to generate possible items to evaluate clinical COPD control. Thereafter, an item reduction questionnaire was sent to 77 international experts. Sixty-seven experts responded and the 10 most important items, divided into 3 domains (symptoms, functional and mental state were included in the CCQ (scale: 0 = best, 6 = worst. Results Cross-sectional data were collected from 119 subjects (57 COPD, GOLD stage I-III; 18 GOLD stage 0 and 44 (exsmokers. Cronbach's ? was high (0.91. The CCQ scores in patients (GOLD 0-III were significantly higher than in healthy (exsmokers. Furthermore, significant correlations were found between the CCQ total score and domains of the SF-36 (? = 0.48 to ? = 0.69 and the SGRQ (? = 0.67 to ? = 0.72. In patients with COPD, the correlation between the CCQ and FEV1%pred was ? =-0.49. Test-retest reliability was determined in 20 subjects in a 2-week interval (Intra Class Coefficient = 0.94. Thirty-six smokers with and without COPD showed significant improvement in the CCQ after 2 months smoking cessation, indicating the responsiveness of the CCQ. Conclusion The CCQ is a self-administered questionnaire specially developed to measure clinical control in patients with COPD. Data support the validity, reliability and responsiveness of this short and easy to administer questionnaire.

The Emotional Appetite Questionnaire (EMAQ) comprises ratings of tendency to eat in response to both positive and negative, emotions and situations. To assess construct validity, the responses of 232 male and female participants to the EMAQ subscales were correlated with the subscales of the Dutch Eating Behavior Questionnaire (DEBQ), which has been extensively validated. In addition, the EMAQ scores were correlated with BMI. Convergent validity was demonstrated by a significant positive correlation between the negative emotions and situations scores of the EMAQ and the emotional eating subscale score of the DEBQ (DEBQ-E). Moreover, discriminant validity was demonstrated by low correlations of EMAQ positive emotions and situations scores with the DEBQ-E score. For the study sample, the EMAQ negative scores were significantly positively correlated with BMI, and the EMAQ positive scores were significantly inversely correlated with BMI. As BMI increased so did reported negative emotional and situational eating whereas as BMI decreased, reported positive emotional and situational eating increased. Although causality cannot be inferred from correlations, eating more under negative emotions may contribute to being overweight whereas eating less may contribute to being underweight. The EMAQ was shown to have construct validity, and emotional eating was significantly correlated with BMI. PMID:20005275

In measuring the quality of life of burn victims, it is essential that we find reliable and valid means. The Burn Sexuality Questionnaire (BSQ) is a specific instrument that assesses sexuality in the context of quality of life of burn victims. We set out to translate, validate and culturally adapt the BSQ into Brazilian Portuguese. The Portuguese version was applied to 80 patients. After translation, cultural adaptation was performed with 30 patients. We also tested the final version for reliability in 20 patients, and for face, content and construct validities in 30 patients, according to standard procedures. Total Cronbach's alpha was 0.87. Pearson's correlation was significant between scores for different time points. Construct validity was demonstrated with the correlation of the BSQ with the Burn Specific Health Scale-Revised (BSHS-R) questionnaire. It showed significant correlation between the BSQ social comfort domain and the BSHS-R affect and body image (p=0.025), simple function ability (p=0.008), work (p=0.016) and treatment (p=0.037) domains. This cultural adaptation of the BSQ suggests that it is a reliable tool and has construct validity for the social comfort domain. There is still need for a better-structured tool that could possibly evaluate functional and psychological aspects of sexuality, because one could easily overlook the psychosocial aspects of patients with major, complex burns.

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
ABSTRACT The Perceived Leadership Communication Questionnaire (PLCQ) is a short, reliable, and valid instrument for measuring leadership communication from both perspectives of the leader and the follower. Drawing on a communication-based approach to leadership and following a theoretical framework of interpersonal communication processes in organizations, this article describes the development and validation of a one-dimensional 6-item scale in four studies (total N = 604). Results from Study 1 and 2 provide evidence for the internal consistency and factorial validity of the PLCQ's self-rating version (PLCQ-SR)-a version for measuring how leaders perceive their own communication with their followers. Results from Study 3 and 4 show internal consistency, construct validity, and criterion validity of the PLCQ's other-rating version (PLCQ-OR)-a version for measuring how followers perceive the communication of their leaders. Cronbach's ? had an average of.80 over the four studies. All confirmatory factor analyses yielded good to excellent model fit indices. Convergent validity was established by average positive correlations of.69 with subdimensions of transformational leadership and leader-member exchange scales. Furthermore, nonsignificant correlations with socially desirable responding indicated discriminant validity. Last, criterion validity was supported by a moderately positive correlation with job satisfaction (r =.31). PMID:25511204

Full Text Available Abstract Background The development and validation study of the Clinical Chronic Obstructive Disease (COPD Questionnaire (CCQ has recently been published in this journal. The CCQ is the first questionnaire that incorporates both clinician and patient guideline goals in the clinical control evaluation of patients with COPD in general clinical practice. The aim of this study is the validation of the CCQ questionnaire in Italian, in specific pulmonary disease clinical practice. Methods Validity was tested on a population of healthy subjects and patients with COPD, using the Italian validated version of the Short Form Health Survey (SF-36 and guideline recommended routine measurement in COPD patients (FEV1, FVC, BMI and functional dyspnoea. Test-retest reliability was tested by re-administering the CCQ after 2 weeks. Responsiveness was tested by re-administering the CCQ after three weeks of hospital pulmonary rehabilitation. Distance walked and Borg breathlessness rating were measured at the end of the six-minute walking test (6 MWT, before and after rehabilitation. Results Cross-sectional data were collected from 175 subjects (55 healthy; 40 mild-moderate, 50 severe and 25 very severe COPD. Cronbach's alpha was high (0.89. The CCQ scores in patients were significantly worse than in healthy subjects. The CCQ total score in patients with COPD was significantly worse in those with BMI Conclusions The CCQ is self-administered and has been specially developed to measure clinical control in patients with COPD. Data support its validity, reliability and responsiveness in Italian and in specific pulmonary disease clinical practice.
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.

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.

Full Text Available The paper is based on the results of a research that aimed to identify the factors influencing school inclusion among disadvantagedstudents. The main outcome of the research was the development of the SSP-School Inclusion Questionnaire, intended to: (1measure school inclusion levels among students; (2 identify students with significantly lower levels of school inclusion, whoneed to be included in intervention programs; and (3 measure the impact of intervention programs using subjective indicators(beneficiaries’ perception of school and teachers, feelings of safety in school, school performance. The questionnaire was completedby 480 vocational school students aged 15-19 from a large developed urban area (Cluj-Napoca in Romania. The purpose of theresearch was to test the validity and reliability of the instrument and to propose it to professionals working in education (schoolpsychologists, school counsellors etc. for efficient data collection and for measuring the impact of educational intervention.
We assessed the validity of the Boston Teacher Questionnaire in a sample of 3451 9-year-old children. Those identified by the questionnaire as having a learning difficulty syndrome were compared to those without any characteristic of that syndrome. The validity reference measures were individually administered neuropsychological assessments at age 7 years and a group-administered reading achievement test at age 9 years. Girls and boys with the reading syndrome had much lower reading scores at age 9 years than did their peers. Boys, but not girls, with the arithmetic syndrome were much more likely than their peers to have arithmetic scores more than one grade below the expected level at age 7 years. Girls and boys with the tasks syndrome, characterized by impersistence, dependence, and inflexibility, were more likely than those without any features of the syndrome to be classified as having little or no goal orientation by a neuropsychologist who assessed the children in an office setting. Similarly, the neuropsychologist was much more likely than expected to have classified children with the attention syndrome as having a short attention span, and to have classified boys, but not girls, with the hyperactivity syndrome as having an unusual/extreme level and nature of overactivity. Children with any syndrome were more likely than others to have low scores on components of the Wechsler Intelligence Scale for Children, items of the Bender-Gestalt Test that assessed integration and distortion, and measures of reading comprehension. We conclude that the Boston Teacher Questionnaire validly identifies children with learning problems. PMID:8445172

Current measures for major depressive disorder focus primarily on the assessment of depressive symptoms, while often omitting other common features. However, the presence of comorbid features in the anxiety spectrum influences outcome and may effect treatment. More comprehensive measures of depression are needed that include the assessment of symptoms in the anxiety-depression spectrum. This study examines the reliability and validity of the Symptoms of Depression Questionnaire (SDQ), which assesses irritability, anger attacks, and anxiety symptoms together with the commonly considered symptoms of depression. Analysis of the factor structure of the SDQ identified 5 subscales, including one in the anxiety-depression spectrum, with adequate internal consistency and concurrent validity. The SDQ may be a valuable new tool to better characterize depression and identify and administer more targeted interventions. PMID:25275853

People engage in gambling behaviour for a variety of different reasons, some of which are riskier than others in terms of associations with heavy and problem gambling. Stewart and Zack (Addiction 103:1110-1117, 2008) developed a measure called the Gambling Motives Questionnaire (GMQ) that assesses levels of three distinct gambling motives: enhancement (to increase positive emotions), coping (to decrease negative emotions), and social (to increase affiliation). While this measure has been validated in a community-recruited sample of middle-aged gamblers, the GMQ has yet to be validated in emerging adulthood (ages 18-25 years)-a developmental period associated with increased risk for heavy and problematic gambling. The current project tested the psychometric properties of the GMQ in a community sample of emerging adult gamblers using archival data from the Manitoba Longitudinal Study of Young Adults. Participants (N = 487; 73.9 % Caucasian; 52.6 % female; mean age 22.23 years) completed the GMQ and questionnaire measures of gambling behaviour and problems. Exploratory factor analysis revealed that a three-factor model adequately fit the data; however, problematic items were identified. A modified 9-item version of the GMQ with the problem items removed fit the data well. Both the original 15-item and the 9-item versions had acceptable subscale alpha reliabilities (?s >.78). While all three subscales (from both the 9-item and 15-item versions) were positively correlated with problem gambling, only enhancement motives emerged as a significant independent predictor when the other motives and gambling behaviours were entered as simultaneous predictors. These results suggest the GMQ is a valid measure for tapping motives in emerging adults, and that high enhancement motives are particularly predictive of gambling problems in this developmental period. Future intervention efforts might specifically target enhancement motives in emerging adults. PMID:24871297

The Seizure Severity Questionnaire (SSQ) was developed to evaluate changes in seizure severity and bothersomeness. Determination of a threshold value reflecting meaningful patient benefit on the SSQ would improve clinical interpretation of scale results. The objective of this analysis was to define a minimally important change (MIC) threshold for the SSQ, using data from patients with treatment-resistant partial-onset seizures from two clinical trials (N=776). Minimally important change thresholds were calculated using standard anchor-based methods, with the Patient Global Impression of Change (PGIC) score as the anchor with the categories of 'much improved,' 'minimally improved,' 'much worsened,' and 'minimally worsened' combined. The calculated MIC thresholds (range: 0.34 to 0.50) suggest that a 0.48-point change in the SSQ total score reflects a clinically meaningful change in seizure severity from the patients' perspective.

PURPOSE: Information about physical activity (PA) in Greenland is limited, partly due to 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 collected by face-to-face interview and ACC+HR monitoring among Inuit (18+years) in Greenland during 2005-2010 (n=1508). Physical activity 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, P1.5hrs/day, p

A nursing job satisfaction questionnaire was designed by a project group of nurses seeking a suitable job satisfaction measure to track as an outcome in a large Sydney hospital-wide models of nursing care project. Existing tools were rejected by the group as overly lengthy, US-biased and over-using respondent assessment of the character of the work environment as a proxy for job satisfaction, or happiness at work. A one-page, 14-item tool was developed after instrument reviewing and facilitated groupwork. The tool reduces to three measurable domains: intrinsic, extrinsic and relational job satisfaction. Exploratory factor analysis (n = 220 responses) confirmed the validity of this 'three-way' conceptualisation of nursing job satisfaction. Internal consistency analysis on a larger sample of responses (n = 459) yielded high Cronbach's Alpha values for all three domains and for the total overall, suggesting a stable and reliable measure. The NWSQ is short, one page, sensibly worded for Australian conditions and yields scoring against three validated domains. It holds significant potential utility as a standard metric for prospective ward-based or institution-wide performance trending. PMID:20230168

Acceptance and Commitment Therapy (ACT) emphasizes the relationship a person has with their thoughts and beliefs as potentially more relevant than belief content in predicting the emotional and behavioral consequences of cognition. In ACT, "defusion" interventions aim to "unhook" thoughts from actions and to create psychological distance between a person and their thoughts, beliefs, memories, and self-stories. A number of similar concepts have been described in the psychology literature (e.g., decentering, metacognition, mentalization, and mindfulness) suggesting converging evidence that how we relate to mental events may be of critical importance. While there are some good measures of these related processes, none of them provides an adequate operationalization of cognitive fusion. Despite the centrality of cognitive fusion in the ACT model, there is as yet no agreed-upon measure of cognitive fusion. This paper presents the construction and development of a brief, self-report measure of cognitive fusion: The Cognitive Fusion Questionnaire (CFQ). The results of a series of studies involving over 1,800 people across diverse samples show good preliminary evidence of the CFQ's factor structure, reliability, temporal stability, validity, discriminant validity, and sensitivity to treatment effects. The potential uses of the CFQ in research and clinical practice are outlined. PMID:24411117

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.

Depression is often underdiagnosed and undertreated in primary care settings, particularly in developing countries. This is, in part, due to challenges resulting from lack of skilled mental health workers, stigma associated with mental illness, and lack of cross-culturally validated screening instruments. We conducted this study to evaluate the reliability and validity of the Patient Health Questionnaire-9 (PHQ-9) as a screen for diagnosing major depressive disorder among adults in Ethiopia, the second most populous country in sub-Saharan Africa. A total of 926 adults attending outpatient departments in a major referral hospital in Ethiopia participated in this study. We assessed criterion validity and performance characteristics against an independent, blinded, and psychiatrist administered semi-structured Schedules for Clinical Assessment in Neuropsychiatry (SCAN) interview. Overall, the PHQ-9 items showed good internal (Cronbach's alpha=0.81) and test re-test reliability (intraclass correlation coefficient=0.92). A factor analysis confirmed a one-factor structure. Receiver Operating Characteristics (ROC) analysis showed that a PHQ-9 threshold score of 10 offered optimal discriminatory power with respect to diagnosis of major depressive disorder via the clinical interview (sensitivity=86% and specificity=67%). The PHQ-9 appears to be a reliable and valid instrument that may be used to diagnose major depressive disorders among Ethiopian adults. PMID:23972787

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.

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. PMID:24077356

Abstract The purpose of the study was to develop and validate a conceptually and psychometrically sound conflict questionnaire for sport. The development process involved 3 phases: (a) a qualitative phase, (b) a content and factorial validity phase and (c) a construct validity phase. A total of 50 items were generated and sent to 6 experts to determine content validity. Through this process, 25 items were retained and administered to a sample of athletes (n = 437) to determine factorial validity. Based on these results, a second sample (n = 305) was administered the 14-item version of the Group Conflict Questionnaire along with the Group Environment Questionnaire, the Athlete Satisfaction Questionnaire and the Passion Scale to test convergent, discriminant and known-group difference validity. Cross-validation from both samples via confirmatory factor analysis yielded moderate-to-acceptable model fit, thus supporting factorial validity for the 14-item version. Additionally, initial support for convergent validity and known-group difference validity and partial support for discriminant validity were found. A sport-specific conflict questionnaire is now available for researchers to utilise. Results and research implications are discussed. PMID:25358085

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.

Full Text Available Abstract Background Venous blood sampling is a common procedure in health care. It is strictly regulated by national and international guidelines. Deviations from guidelines due to human mistakes can cause patient harm. Validated questionnaires for health care personnel can be used to assess preventable "near misses"--i.e. potential errors and nonconformities during venous blood sampling practices that could transform into adverse events. However, no validated questionnaire that assesses nonconformities in venous blood sampling has previously been presented. The aim was to test a recently developed questionnaire in self reported venous blood sampling practices for validity and reliability. Findings We developed a questionnaire to assess deviations from best practices during venous blood sampling. The questionnaire contained questions about patient identification, test request management, test tube labeling, test tube handling, information search procedures and frequencies of error reporting. For content validity, the questionnaire was confirmed by experts on questionnaires and venous blood sampling. For reliability, test-retest statistics were used on the questionnaire answered twice. The final venous blood sampling questionnaire included 19 questions out of which 9 had in total 34 underlying items. It was found to have content validity. The test-retest analysis demonstrated that the items were generally stable. In total, 82% of the items fulfilled the reliability acceptance criteria. Conclusions The questionnaire could be used for assessment of "near miss" practices that could jeopardize patient safety and gives several benefits instead of assessing rare adverse events only. The higher frequencies of "near miss" practices allows for quantitative analysis of the effect of corrective interventions and to benchmark preanalytical quality not only at the laboratory/hospital level but also at the health care unit/hospital ward.

The reproducibility and validity of a food frequency questionnaire designed to measure intakes of total fat, saturated and polyunsaturated fats, vitamins A, C, and E, selenium, and dietary fiber were tested from March to October 1984 among 297 Finnish men aged 55-69 years. The questionnaire asked about consumption of 44 food items. In the reproducibility study, 107 subjects filled in the questionnaire three times, at three-month intervals. Intraclass correlations varied from 0.52 for vitamin A to 0.85 for polyunsaturated fat. In the validity study, 190 subjects kept food consumption records for 12 two-day periods distributed evenly over a period of six months and filled in the questionnaire both before and after this period. Correlations between the nutrient intake values from the food records and those from the food frequency questionnaires ranged from 0.33 for selenium to 0.68 for polyunsaturated fat. On the average, 40-45% of the subjects in the lowest and highest quintiles based on food records were in the same respective quintiles when assessed by the food frequency questionnaire, and 70-75% were in the two lowest and two highest questionnaire quintiles, respectively. The food frequency questionnaire and a quantitative food use questionnaire tested in the same study were compared. Use of these two instruments in large-scale epidemiologic studies is discussed.

Objective The Metacognitions Questionnaire 30 assesses metacognitive beliefs and processes which are central to the metacognitive model of emotional disorder. As recent studies have begun to explore the utility of this model for understanding emotional distress after cancer diagnosis, it is important also to assess the validity of the Metacognitions Questionnaire 30 for use in cancer populations. Methods 229 patients with primary breast or prostate cancer completed the Metacognitions Questionnaire 30 and the Hospital Anxiety and Depression Scale pre-treatment and again 12 months later. The structure and validity of the Metacognitions Questionnaire 30 were assessed using factor analyses and structural equation modelling. Results Confirmatory and exploratory factor analyses provided evidence supporting the validity of the previously published 5-factor structure of the Metacognitions Questionnaire 30. Specifically, both pre-treatment and 12 months later, this solution provided the best fit to the data and all items loaded on their expected factors. Structural equation modelling indicated that two dimensions of metacognition (positive and negative beliefs about worry) were significantly associated with anxiety and depression as predicted, providing further evidence of validity. Conclusions These findings provide initial evidence that the Metacognitions Questionnaire 30 is a valid measure for use in cancer populations. PMID:25215527

The purpose of this study was to translate and culturally adapt the Carpal Tunnel Questionnaire to produce an equivalent Korean version. A total of 53 patients completed the Korean version of the Carpal Tunnel Questionnaire pre-operatively and 3 months after open carpal tunnel release. All 53 also completed the Korean version of the Disabilities of Arm, Shoulder, and Hand questionnaire pre-operatively and 3 months post-operatively. Reliability was measured by determining the test-retest reliability and internal consistency. Test-retest reliability was assessed using intraclass correlation coefficients and paired t-tests, and internal consistency using Cronbach's alpha coefficients. Pearson correlation analysis was carried out on the Korean version of the Carpal Tunnel Questionnaire scores and the Korean version of the Disabilities of Arm, Shoulder, and Hand scores to assess construct validity. Responsiveness was evaluated using effect sizes and standardized response means. The reliability of the Korean version of the Carpal Tunnel Questionnaire was good. The scores in the Korean version of the Disabilities of Arm, Shoulder, and Hand strongly correlated with the scores in the Korean version of the Carpal Tunnel Questionnaire. Standardized response mean and effect size were both large for the Korean version of the Carpal Tunnel Questionnaire. The study shows that the Korean version of the Carpal Tunnel Questionnaire is a reliable, valid and responsive instrument for measuring outcomes in carpal tunnel syndrome. PMID:25005562

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.

Reliability analysis showed satisfactory result (Cronbach's alpha coefficient = 0.87. Convergent validity indicated a significant negative correlation between the GHQ-12 and global quality of life scores as expected (r = -0.56, P Conclusion The study findings showed that the Iranian version of the GHQ-12 has a good structural characteristic and is a reliable and valid instrument that can be used for measuring psychological well being in Iran.
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.

Nasal symptoms are the main elements that lead to a therapeutic decision and allow for evaluating treatment effects or natural evolution. Despite availability of several questionnaires with good measurement qualities, no systematic assessment takes into account the specific physical and psychosocial consequences of each of the six main nasal symptoms, independently of the disease. We proposed to measure these symptoms with the use of a self-reporting questionnaire and to test the validity of the questionnaire in a large representative sample of patients attending outpatient rhinologic clinics. The study was conducted in two parts: (1) expert-based development and testing of the face validity of a questionnaire in French; and (2) validity testing, including construct validity by factor analysis, reproducibility by intraclass correlation coefficient (ICC) and Bland and Altman plots, and sensitivity to change by standardized response means, on a large sample of patients in a prospective multicenter study. DyNaChron, a questionnaire with 78 items divided into six domains and exploring both the physical and psychosocial repercussions of CND, was developed. In total, 759 patients completed the questionnaire at a first visit to a clinic, and 539 again 19.5 days later, on average. The questionnaire structure was confirmed to be composed of six domains (6 factors explaining 68.7% of the variance), with two dimensions in each domain. The questionnaire's convergent validity was confirmed; the Cronbach alpha coefficient for domains was high (0.93-0.96), the ICC ranged from 0.8 to 0.92, and the questionnaire's sensitivity to change was greater for patients with improved health status than for those with worsened status. DyNaChron is a well-structured questionnaire with a high degree of internal consistency and all properties needed to be used in research. It should now be compared with other questionnaires and objective measures to assess whether or not DyNaChron better measures disease severity and its changes. Further work will involve shortening the instrument for use in clinical practice and create a "patient symptomatology score". PMID:21739093

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.

The back-translation method was used for translation. An expert committee further developed it for use in a study of injuries in handball, orienteering, tennis, and volleyball. A 10-week pretest was then conducted on 43 athletes, average age 21 (18-31) from these sports, during which time the athletes completed the modified OSTRC questionnaire on a weekly basis. In the 10th week, four additional questions were added in order to examine the questionnaire's content validity. No major disagreement was found in the translation. The athletes perceived the web-based questionnaire to be smooth and easy to complete, accurately capturing overuse injuries. However, suggestions were made to add questions relating to the hip for orienteerers and to the hand/fingers for handball players. The average prevalence of overuse injuries for all athletes, in any anatomical area was 22% (95% confidence interval 20-25). Construct validity appeared to be high, and we therefore suggest that the questionnaire may be used when studying overuse injuries in different sports. PMID:24313387

Full Text Available The Arab Teens Lifestyle Study (ATLS is a multicenter project for assessing the lifestyle habits of Arab adolescents. This study reports on the convergent validity of the physical activity questionnaire used in ATLS against an electronic pedometer. Participants were 39 males and 36 females randomly selected from secondary schools, with a mean age of 16.1 ± 1.1 years. ATLS self-reported questionnaire was validated against the electronic pedometer for three consecutive weekdays. Mean steps counts were 6,866 ± 3,854 steps/day with no significant gender difference observed. Questionnaire results showed no significant gender differences in time spent on total or moderate-intensity activities. However, males spent significantly more time than females on vigorous-intensity activity. The correlation of steps counts with total time spent on all activities by the questionnaire was 0.369. Relationship of steps counts was higher with vigorous-intensity (r = 0.338 than with moderate-intensity activity (r = 0.265. Pedometer steps counts showed higher correlations with time spent on walking (r = 0.350 and jogging (r = 0.383 than with the time spent on other activities. Active participants, based on pedometer assessment, were also most active by the questionnaire. It appears that ATLS questionnaire is a valid instrument for assessing habitual physical activity among Arab adolescents.

Full Text Available Abstract 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.
Full Text Available Background and Objective: In any research work, the tools used to approach the designed project goals should be evaluated. The purpose of the present study was to obtain validity and reliability of the questionnaire of student ratings of teaching in Ahvaz JundiShapur University of Medical Sciences. Subjects and Methods: The questionnaire of student ratings of teaching was evaluated in a descriptive study. In this study the views of 70 expert faculty members and 5420 completed questionnaire by students were used. To investigate the reliability, two methods of split-half and internal consistency (Cronbach's Alpha were applied, and the validity was determined by three aspects of construct validity (factor analysis, concurrent validity and content validity. The Data were analyzed by SPSS-15 software.Results: The factor analysis revealed 2 factors as tutor capability and expert teaching, which could explain 67.69 % of the total variance. The concurrent validity coefficiency was determined as 0.538 for the first 14 questions in comparison to question number 15. Within content validity the coefficient of all items was determined as 0.920. The internal consistency of questions showed a high correlation of all 15 questionnaire items. The Cronbach’s alpha was 0.947 % and split-half reliability was 0.884%. Conclusion: It is concluded that student ratings questionnaire with a reasonable degree of validity and reliabilitycould be accounted as a suitable tool to evaluate the University teaching conditions.Sci Med J 2012; 10(6:583-593
Full Text Available Patients suffered from DM, face many difficulties in compliance to medical instructions, because the DM type II may be asymptomatic at the beginning and that is the reason that recommended dietary and lifestyle changes may seem unnecessary. The aim of the study was to develop a specific instrument measuring compliance to treatment in patient with DM II and test the validity and reliability of the instrument in Greek people. Method and material: This instrument was created using 38 questions from existing questionnaires. The questionnaires used were: Summary of Diabetes Self-Care Activities, 9-item Patient Health Questionnaire, 12-item Short Form Health Survey and Diabetes Self-care Behaviours and Barriers instrument. The translation process from English into Greek was undertaken following the guidelines provided by the International Committee of this instrument. Several issues related to the best possible translation and validation of the various dimensions and levels of the instrument were taken into account. Then the instrument was tested to a representative sample of 120 individuals. Results: Using the scale reliability of the Flesch-Kincaid, the reliability of the questionnaire was 6.7. The average time for completing the questionnaire was eight minutes (SD ± 4.2 minutes. The instrument presents construct validity, discriminant ability, reliability and sensitivity to change. Conclusions: The present instrument requires considerable time to complete it. Therefore it is a reliable and valid instrument which can be used effectively in compliance of therapy measurement in Greek population.
BACKGROUND: Impairments in work productivity and daily activities contribute to the burden of rheumatoid arthritis (RA). It is thus essential to use an instrument assessing both work and daily activity impairments when studying the full impact of RA on individuals. The Work Productivity and Activity Impairment (WPAI) questionnaire is such an instrument. OBJECTIVE: This study aims to linguistically validate the RA-specific WPAI (WPAI:RA) instrument in 20 new languages and to assess its content validity for individuals with RA. METHODS: The linguistic validation of the questionnaire followed a standard methodology that included comprehension test interviews (n = 5 individuals with RA per language) to assess the relevance, understanding and acceptability of the WPAI:RA. Content validity of the instrument was simultaneously investigated. RESULTS: Comprehension testing showed that the WPAI:RA questionnaire was well understood similarly across countries; minor changes were made to ensure fidelity to the originalconcepts and for ease of comprehension. The majority of interviewees (66/93) considered its content comprehensive and appropriate to measure their ability to work and perform daily activities. CONCLUSION: The WPAI:RA questionnaire is now linguistically validated in 20 new languages [Czech (Czech Republic), Dutch (Belgium), English (Canada and UK), French (Belgium, Canada and France), German (Germany), Hungarian (Hungary), Italian (Italy), Polish (Poland), Portuguese (Brazil), Romanian (Romania), Russian (Russia and Ukraine), Spanish (Argentina, Mexico, Spain and US) and Ukrainian (Ukraine)]. The WPAI:RA questionnaire shows good content validity. It can thus be used in multi-country clinical trials to assess RA-related impact on the patients' ability to work and perform daily activities.

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.

Full Text Available This study aimed to develop and validate a de novo food frequency questionnaire for self-defined vegans in the United States. Diet histories from pilot samples of vegans and a modified ‘Block Method’ using seven selected nutrients of concern in vegan diet patterns, were employed to generate the questionnaire food list. Food frequency responses of 100 vegans from 19 different U.S. states were obtained via completed mailed questionnaires and compared to multiple telephone-conducted diet recall interviews. Computerized diet analyses were performed. Correlation coefficients, t-tests, rank, cross-tabulations, and probability tests were used to validate and compare intake estimates and dietary reference intake (DRI assessment trends between the two methods. A 369-item vegan-specific questionnaire was developed with 252 listed food frequency items. Calorie-adjusted correlation coefficients ranged from r = 0.374 to 0.600 (p < 0.001 for all analyzed nutrients except calcium. Estimates, ranks, trends and higher-level participant percentile placements for Vitamin B12 were similar with both methods. Questionnaire intakes were higher than recalls for most other nutrients. Both methods demonstrated similar trends in DRI adequacy assessment (e.g., significantly inadequate vitamin D intake among vegans. This vegan-specific questionnaire can be a useful assessment tool for health screening initiatives in U.S. vegan communities.

Abstract in english Introduction: The Dietary Sodium Restriction Questionnaire (DSRQ) was designed to assess attitudes and behaviors of patients with heart failure (HF) related to following a low-sodium diet. Recently, it has been translated and culturally adapted for use in Brazil. However, further validation of the i [...] nstrument is required before it can be used in the management of patients with HF in Brazil. Objective: To test the reliability and validity of the Brazilian version of the DSRQ. Methods: Face and content validity were assessed by a panel of experts. Construct validity was tested using exploratory and confirmatory factor analysis. Reliability was tested using Cronbach's alpha to assess the internal consistency of the instrument. Results: A total of 206 systolic HF outpatients were assessed (mean age, 60.4 ± 11.9 years). Face and content validity analysis showed equivalence between the Brazilian version and the original instrument. In the exploratory factor analysis, the principal component analysis (PCA) yielded four factors with eigenvalues greater than 1. Three models were tested in the confirmatory factor analysis, and the three-factor model resulting from the PCA showed the best fit, accounting for 49% of the variance. Alpha values obtained for the attitude/ subjective norm, perceived behavioral control, and dependent behavior subscales were 0.71, 0.67, and 0.79, respectively. Conclusions: Our results suggest that the final validated Brazilian version of the DSRQ is a valid and reliable tool for measuring attitudes and behaviors related to following a low-sodium diet in Brazilian patients with HF.

Full Text Available Objectives: To initiate the process of validation of an instrument based on an American self-reported questionnaire named RAB (Risk Assessment Battery -- called CRA in its Brazilian version --, which covers aspects related to drug use, HIV testing, sexual behavior and concern with the transmission of the virus. The questionnaire was back-translated and its concurrent validity was tested, as well as the utility of an Overall Risk Score (ORS for the transmission of the HIV virus or of subscores for Drug Use (SDU or Sexual Risk (SSR. Methods: Case vignettes of ten typical cases had their questionnaire scores compared with the impression of independent referees. Results: There were systematic differences in the comparison with the specific referees for each area, suggesting that only the ORS has clinical validity, specifically regarding the exposure to risk of infection/reinfection by HIV. Conclusion: The questionnaire in its current use and format is not adequate to express impairment already caused by exposure to the virus. The specific subscores were not clinically valid to express such risk, and the instrument needs the addition of a more comprehensive section about intravenous drug use to be used in future studies.

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.

The Health Outcomes Burn Questionnaire (HOBQ) is a self-administered questionnaire to monitor outcome after burns in young children. This study aimed to assess feasibility, reliability and validity of the Dutch version of the HOBQ. The HOBQ was adapted into Dutch and tested in a population of children aged 0-4 years with a primary admission to a Dutch burn centre in March 2001-February 2004. Parents of 413 children were sent a questionnaire. To assess validity, a generic outcome instrument was included, the Infant Toddler Quality of Life Questionnaire (ITQOL). The response rate was 50.0% (n=196). Mean self-reported completion time was 16.7 min. The internal consistency of all the HOBQ-scales was good (Cronbach's alpha's>0.69). Test-retest results showed no differences in 7 out of 10 scales. High correlations between HOBQ-scales and conceptually equivalent ITQOL and scales were found in 5 out of 7 comparisons. The majority of the HOBQ-scales (7 out of 10) showed significant differences in the expected direction between children with a long versus short length of stay. Our data support the reliability and validity of the Dutch HOBQ. The HOBQ can be used as a research tool, to monitor functional outcome after burns in young children. Further research in other samples is recommend to fully establish the reliability and validity of the HOBQ. PMID:16487664

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.

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.
Full Text Available Abstract Background Musculoskeletal disorders (MSDs are a major health problem in the world. Self-reported questionnaires are a known method for estimating the prevalence of MSDs among the population. One of the studies concerning MSDs and their relation to work-related physical and psychosocial factors, as well as non-work-related factors, is the MUSIC-Norrtalje study in Sweden. In this study, the research group developed a questionnaire, which has been validated during its development process and is now considered a well-known instrument. The aim of this study is to validate the Persian version of this questionnaire. Methods The first step was to establish two expert panel groups in Iran and Sweden. The Focus Group Discussion (FGD method was used to detect questionnaire face and content validity. To detect questionnaire reliability, we used the test-retest method. Results Except for two items, all other questions that respondents had problems with in the focus group (20 of 297, had unclear translations; the ambiguity was related to the stem of the questions and the predicted answers were clear for the participants. The concepts of 'household/spare time' and 'physical activity in the workplace' were not understood by the participants of FGD; this has been solved by adding further descriptions to these phrases in the translation. In the test-retest study, the reliability coefficient was relatively high in most items (only 5 items out of 297 had an ICC or kappa below 0.7. Conclusion The findings from the present study provide evidence that the Persian version of the MUSIC questionnaire is a reliable and valid instrument.
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.
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.
Despite the common use of the 12-item General Health Questionnaire (GHQ-12) with adolescents, there is limited data supporting its validity with this population. The aims of the study were to investigate the psychometric properties of the GHQ-12 among high school students, to validate the GHQ-12 against the gold standard of a diagnostic interview, and to suggest a threshold score for detecting depressive and anxiety disorders. Six hundred and fifty-four high school students from years 10 to 12 (ages 15-18) completed the GHQ-12 (Likert scored) and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV-Test Revision (DSM-IV-TR). Receiver operating characteristic (ROC) curves were plotted. The mean GHQ-12 score for the total sample was 9.9 (S.D.=5.4). Results from the ROC curve indicated that the GHQ-12 performed better than chance at identifying depressive and anxiety disorders (area under the curve (AUC)=0.781). A GHQ-12 threshold score of 9/10 for males and 10/11 for females was found to be optimal. Given the significant proportion of mental illness among high school students, there may be a need to introduce screening for mental illnesses as part of the school curriculum. This can assist with the early identification and enable low stigma preventive intervention within the school environment. PMID:21067813

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.

The Nijmegen Cochlear Implant Questionnaire (NCIQ) is a specific and quantifiable self-assessment health-related quality of life (QoL) questionnaire. It was developed to determine the subjective benefits of a cochlear implant (CI). The present study aimed to determine the validity and reliability of the NCIQ in Spanish. Seventy-six adult, Spanish speaking, CI users and 28 control subjects answered the NCIQ. Reliability of the questionnaire was determined using Cronbach's ? coefficient and the validity established using Pearson's correlation coefficient. All questionnaire respondents performed significantly better in all sub-domains with a cochlear implant than before cochlear implantation. The Cronbach's ? score exceeded 0.70 in most sub-domains and the total score. The objective measures: bisyllables tested without lip-reading and with masking; and bisyllables, tested without lip-reading and without masking were correlated with the sub-domain 'advanced sound perception'. To determine health-related QoL the NCIQ in Spanish is a reliable self-assessment questionnaire and a valuable instrument in determining the subjective benefit of a CI. PMID:24609736

Full Text Available Abstract Background Clinical outcome measures are important tools to monitor patient improvement during treatment as well as to document changes for research purposes. The short-form Bournemouth questionnaire for neck pain patients (BQN was developed from the biopsychosocial model and measures pain, disability, cognitive and affective domains. It has been shown to be a valid and reliable outcome measure in English, French and Dutch and more sensitive to change compared to other questionnaires. The purpose of this study was to translate and validate a German version of the Bournemouth questionnaire for neck pain patients. Methods German translation and back translation into English of the BQN was done independently by four persons and overseen by an expert committee. Face validity of the German BQN was tested on 30 neck pain patients in a single chiropractic practice. Test-retest reliability was evaluated on 31 medical students and chiropractors before and after a lecture. The German BQN was then assessed on 102 first time neck pain patients at two chiropractic practices for internal consistency, external construct validity, external longitudinal construct validity and sensitivity to change compared to the German versions of the Neck Disability Index (NDI and the Neck Pain and Disability Scale (NPAD. Results Face validity testing lead to minor changes to the German BQN. The Intraclass Correlation Coefficient for the test-retest reliability was 0.99. The internal consistency was strong for all 7 items of the BQN with Cronbach ?'s of .79 and .80 for the pre and post-treatment total scores. External construct validity and external longitudinal construct validity using Pearson's correlation coefficient showed statistically significant correlations for all 7 scales of the BQN with the other questionnaires. The German BQN showed greater responsiveness compared to the other questionnaires for all scales. Conclusions The German BQN is a valid and reliable outcome measure that has been successfully translated and culturally adapted. It is shorter, easier to use, and more responsive to change than the NDI and NPAD.
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 againstthe 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.

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.
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.

Full Text Available Abstract 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 (rs -0.31 to -0.60. Corresponding domains of the LCQ and the SF-36 showed weaker correlations (rs 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

Full Text Available Introduction: Many studies reported poorer quality of life (QoL in youth with diabetes compared to healthy peers. One of the tools used is the Diabetes Quality of Life for Youth (DQoLY questionnaire in English. A validated instrument in Malay is needed to assess the perception of QoL among youth with diabetes in Malaysia. Objective: To translate the modified version, i.e., the DQoLY questionnaire,into Malay and determine its reliability and validity.Methods: Translation and back-translation were used. An expert panel reviewed the translated version for conceptual and content equivalence. The final version was then administered to youths with type 1 diabetes mellitus from the universities and Ministry of Health hospitals between August 2006 and September 2007. Reliability was analysed using Cronbach’s alpha, while validity was confirmed using concurrent validity (HbA1c and self-rated health score.Results: A total of 82 youths with type 1 diabetes (38 males aged 10-18 years were enrolled from eight hospitals. The reliability of overall questionnaire was 0.917, and the reliabilities of the three domains ranged from 0.832 to 0.867. HbA1c was positively correlated with worry (p=0.03. The self-rated health score was found to have significant negative correlation with the “satisfaction” (p=0.013 and “impact” (p=0.007 domains.Conclusion: The Malay translated version of DQoLY questionnaire was reliable and valid to be used among youths with type 2 diabetes in Malaysia.

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.
Full Text Available Background: The Health System Responsiveness Questionnaire is an instrument designed by the World Health Organization (WHO in 2000 to assess the experience of patients when interacting with the health care system. This investigation aimed to adapt a Mental Health System Responsiveness Questionnaire (MHSRQ based on the WHO concept and evaluate its validity and reliability to the mental health care system in Iran. Design: In accordance with the WHO health system responsiveness questionnaire and the findings of a qualitative study, a Farsi version of the MHSRQ was tailored to suit the mental health system in Iran. This version was tested in a cross-sectional study at nine public mental health clinics in Tehran. A sample of 500 mental health services patients was recruited and subsequently completed the questionnaire. Item missing rate was used to check the feasibility while the reliability of the scale was determined by assessing the Cronbach's alpha and item total correlations. The factor structure of the questionnaire was investigated by performing confirmatory factor analysis (CFA. Results: The results showed a satisfactory feasibility since the item missing value was lower than 5.2%. With the exception of access domain, reliability of different domains of the questionnaire was within a desirable range. The factor loading showed an acceptable unidimentionality of the scale despite the fact that three items related to access did not perform well. The CFA also indicated good fit indices for the model (CFI=0.99, GFI=0.97, IFI=0.99, AGFI=0.97. Conclusions: In general, the findings suggest that the Farsi version of the MHSRQ is a feasible, reliable, and valid measure of the mental health system responsiveness in Iran. Changes to the questions related to the access domain should be considered in order to improve the psychometric properties of the measure.

Full Text Available 800x600 Context: The concept of care is a fundamental issue in nursing science. Therefore the development and the use of tools for assessing care is an imperative for the nursing profession. The NDI-35 questionnaire is one such tool for assessing the nursing care. Objectives: The purpose of this paper is to adapt and use the NDI-35 questionnaire in Greek nursing practice. A translation and validation of NDI-35 questionnaire is performed. Methods: Exploratory factor analyses, as well as internal consistency and test–retest analyses, were conducted. Forward translations from English were produced by three independent Greek translators and then back translations by five independent bilingual translators. The Greek NDI-35 questionnaire that was produced was administered to 200 nurses (144 women and 56 men from tertiary and secondary health care facilities. Data were analyzed using principal component analysis and Cronbach’s alpha. Results: One hundred and eighty four nurses that answered the NDI-35 questionnaire were graduates from the Technological Educational Institute (T.E.I. and 64% of the respondents had more than 15 years of professional experience. Two subscales arbitrarily called “clinical work” and “patient needs” emerged, with the mean “clinical work” subscale score being at 70.16 ±12.90 (a maximum of 85 and mean “patient needs” subscale at 21.49± 6.16. Considerable differences in scoring among different items were observed when the NDI-35 answers were compared to their Greek counterparts’. Results confirmed that: (a the translated versions are an accurate translation of the original, (b factor analyses established similar factor solutions as that of the English versions, (c reliability coefficients are satisfactory (i.e., Cronbach's ? coefficients and test–retests, and (d construct validity revealed similarities between English and Greek versions, replications consistent with past research, as well as differences explained through theoretical frameworks. Therefore, both scales were accepted as valid and reliable measures in Greek-speaking populations. Conclusion: Alphas and test-retest correlation suggest the Greek translated and validated NDI-35 questionnaire is a reliable tool for assessing nursing care. Factor analysis and focus group input suggest it is a valid tool. Nurses in different settings may perceive nursing care differently. The findings of the current paper are discussed in the context of nurse education and assessment of care. Normal 0 false false false EL X-NONE X-NONE MicrosoftInternetExplorer4
We aimed to validate a cross-culturally adapted version of the Persian Michigan Hand Outcomes Questionnaire (MHOQ). We followed the Beaton's guideline to translate the questionnaire to Persian. We administered the final version to 223 patients among which 79 patients returned 3 days later to respond to the Persian MHOQ for the second time. In the first visit, respondents also filled the Disabilities of the Arm Shoulder and Hand (DASH) and rated the pain based on the Visual Analogue Scale (VAS). Cronbach's alpha for the total MHOQ was 0.79 which showed good internal consistency. Intraclass correlation coefficient (ICC) for the total MHOQ was 0.84 which demonstrated good reliability between test and retest. The absolute correlation coefficient between total MHOQ and the DASH was as high as 0.74. Persian version of the MHOQ proved to be a reliable and valid instrument to be implemented among Persian population with the hand and wrist disorders. PMID:25609271

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.

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.

Full Text Available Abstract Background Studies on clinical issues, including diagnostic strategies, are considered to be the core content of general practice research. The use of standardised instruments is regarded as an important component for the development of Primary Health Care research capacity. Demand for epidemiological cross-cultural comparisons in the international setting and the use of common instruments and definitions valid to each culture is bigger than ever. Dyspepsia is a common complaint in primary practice but little is known with respect to its incidence in Greece. There are some references about the Helicobacter Pylori infection in patients with functional dyspepsia or gastric ulcer in Greece but there is no specific instrument for the identification of dyspepsia. This paper reports on the validation and translation into Greek, of an English questionnaire for the identification of dyspepsia in the general population and discusses several possibilities of its use in the Greek primary care. Methods The selected English postal questionnaire for the identification of people with dyspepsia in the general population consists of 30 items and was developed in 1995. The translation and cultural adaptation of the questionnaire has been performed according to international standards. For the validation of the instrument the internal consistency of the items was established using the alpha coefficient of Chronbach, the reproducibility (test – retest reliability was measured by kappa correlation coefficient and the criterion validity was calculated against the diagnosis of the patients' records using also kappa correlation coefficient. Results The final Greek version of the postal questionnaire for the identification of dyspepsia in the general population was reliably translated. The internal consistency of the questionnaire was good, Chronbach's alpha was found to be 0.88 (95% CI: 0.81–0.93, suggesting that all items were appropriate to measure. Kappa coefficient for reproducibility (test – retest reliability was found 0.66 (95% CI: 0.62–0.71, whereas the kappa analysis for criterion validity was 0.63 (95% CI: 0.36–0.89. Conclusion This study indicates that the Greek translation is comparable with the English-language version in terms of validity and reliability, and is suitable for epidemiological research within the Greek primary health care setting.

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.

Job Content Questionnaire (JCQ) has been proven a reliable and valid instrument to assess job stress in many countries and among various occupations. In Malaysia, both English and Malay versions of the JCQ have been administered to automotive workers, schoolteachers, and office workers. This study assessed the reliability and validity of the instrument with research laboratory staff in a university. A cross sectional study was conducted among 258 research laboratory staff in Universiti Putra Malaysia (UPM). Malaysian laboratory staff who have worked for at least one year were randomly selected from nine faculties and institutes in the university that have research laboratory. A self-administered English and Malay version of Job Content Questionnaire (JCQ) was used. Three major scales of JCQ: decision latitude, psychological job demands, and social support were assessed. Cronbach's alpha coefficients of two scales were acceptable, decision latitude and psychological job demands (0.70 and 0.72, respectively), while Cronbach's alpha coefficient for social support (0.86) was good. Exploratory factor analysis showed five factors that correspond closely to the theoretical construct of the questionnaire. The results of this research suggest that the JCQ is reliable and valid for examining psychosocial work situations and job strain among research laboratory staff. Further studies should be done for confirmative results, and further evaluation is needed on the decision authority subscale for this occupation. PMID:24968690

Research aimed at evaluating Angina Pectoris (AP) symptoms in patients with Coronary Heart Disease (CHD) requires a comprehensive assessment tool applicable to this population. Because no single existing measure assessed the full range of symptom characteristics important to our study, we combined two measures (the modified Rose Questionnaire (MRQ), and the Short Form-McGill Pain Questionnaire (SF-MPQ) and added one item to examine specific aspects of AP symptoms (Accompanying Symptom Checklist). The purposes of this study are: (i) to describe the process of translating the SF-MPQ, MRQ and accompanying symptom checklist from English to the Farsi language; and (ii) to evaluate substantial psychometric works (content and construct validity) for the entire instrument and each part of it (SF-MPQ, MRQ and accompanying symptom checklist). A cross-cultural adaptation of the instrument was carried out before developing the final version of it. To these ends, one hundred and 10 CHD patients with AP were assessed by this hybrid measure in an initial study. An analysis of the results indicated that a content valid instrument had been developed. There was a significantly high correlation between scores in the SF-MPQ and there were associations between items in the MRQ. The Iranian version of AP characteristics questionnaire is valid; it is capable of describing characteristics of AP symptoms. However, the reliability of the instrument needs to be assessed through further research. PMID:19126076

There is a shortage of quantitative measures for assessing the concept of responsibility as a fundamental construct in medical education, ethics and professionalism in existing literature. This study aimed to develop an instrument for measuring responsibility in both undergraduate and graduate medical students during clinical training. Instrument content was based on literature review and mainly qualitative data obtained from a published grounded theory research. The draft questionnaire (Persian version) was then validated and revised with regard to face and content validity. The finalized 41-item questionnaire consists of four domains that were identified using factor analysis. Test-retest reliability and internal consistency were also assessed. Test-retest reliability was rather high, ranging between 0.70 and 0.75 for all domains. Cronbach’s alpha coefficients were 0.75 – 0.76 for all domains and 0.90 for the composite scale of the whole questionnaire. Correlations between the four domains of the instrument were also satisfactory (r ? 0.47 for most domains). The correlation between each domain and the composite scale was higher than its correlation with other domains (r ? 0.79 for most domains). The instrument demonstrated good construct and internal validity, and can be suitable for measuring the concept of responsibility in practice in different groups of undergraduate and graduate medical trainees (MTs).

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.

Full Text Available Abstract Background To investigate the factor structure, dimensionality and construct validity of the (5-item PRAFAB questionnaire score in women with stress urinary incontinence (stress UI. Methods A cross validation study design was used in a cohort of 279 patients who were randomly divided into Sample A or B. Sample A was used for preliminary exploratory factor analyses with promax rotation. Sample B provided an independent sample for confirming the premeditated and proposed factor structure and item retention. Internal consistency, item-total and subscale correlations were determined to assess the dimensionality. Construct validity was assessed by comparing factor-based scale means by clinical characteristics based on known relationships. Results Factor analyses resulted in a two-factor structure or subscales: items related to 'leakage severity' (protection, amount and frequency and items related to its 'perceived symptom impact' or consequences of stress UI on the patient's life (adjustment and body (or self image. The patterns of the factor loadings were fairly identical for both study samples. The two constructed subscales demonstrated adequate internal consistency with Cronbach's alphas in a range of 0.78 and 0.84 respectively. Scale scores differed by clinical characteristics according to the expectations and supported the construct validity of the scales. Conclusion The findings suggest a two-factorial structure of the PRAFAB questionnaire. Furthermore the results confirmed the internal consistency and construct validity as demonstrated in our previous study. The best description of the factorial structure of the PRAFAB questionnaire was given by a two-factor solution, measuring the stress UI leakage severity items and the perceived symptom impact items. Future research will be necessary to replicate these findings in different settings, type of UI and non-white women and men.

Full Text Available Abstract Background The 'Perception of Anti-Coagulant Treatment Questionnaire' (PACT-Q was developed to assess patients' expectations of, and satisfaction with their anticoagulant treatment. This questionnaire needs to be finalised and psychometrically validated. Methods The PACT-Q was included in the United States, the Netherlands and France into three phase III multinational clinical trials conducted to evaluate efficacy and safety of a new long-acting anticoagulant drug (idraparinux compared to vitamin K antagonist (VKA. PACT-Q was administered to patients with deep venous thrombosis (DVT, atrial fibrillation (AF or pulmonary embolism (PE at Day 1, to assess patients' expectations, and at 3 and 6 months to assess patients' satisfaction and treatment convenience and burden. The final structure of the PACT-Q (Principal Component Analysis – PCA – with Varimax Rotation was first determined and its psychometric properties were then measured with validity of the structure (Multitrait analysis, internal consistency reliability (Cronbach's alpha coefficients and known-group validity. Results PCA and multitrait analyses showed the multidimensionality of the "Treatment Expectations" dimension, comprising 7 items that had to be scored independently. The "Convenience" and "Burden of Disease and Treatment" dimensions of the hypothesised original structure of the questionnaire were combined, thus resulting in 13 items grouped into the single dimension "Convenience". The "Anticoagulant Treatment Satisfaction" dimension remained unchanged and included 7 items. All items of the "Convenience" and "Anticoagulant Treatment Satisfaction" dimensions displayed good convergent and discriminant validity. The internal consistency reliability was good, with a Cronbach's alpha of 0.84 for the "Convenience" dimension, and 0.76 for the "Anticoagulant Treatment Satisfaction" dimension. Known-group validity was good, especially with regard to occurrence of thromboembolic events within 3 months from randomisation. Conclusion The PACT-Q is a valid and reliable instrument that allows the assessment of patients' expectations and satisfaction regarding anticoagulant treatment, as well as their opinion about treatment convenience of use. Its two-part structure – assessment of expectations at baseline in the first part, and of convenience, burden and treatment satisfaction in the second – was validated and displays good and stable psychometric properties. These results are not sufficient to recommend the use of satisfaction as primary endpoint in clinical trials; further validation work is needed to support the interpretation of PACT-Q dimension scores. However, this first validation makes the PACT-Q an appropriate measure for use in clinical and pharmacoepidemiological research, as well as in real-life studies.

Full Text Available Objective: In this study, it is aimed to evaluate the validity and reliability of the Beliefs About Substance Use Questionnaire (BSU which was originally developed by Wright (1993. Method: Seventy alcohol addicted inpatients, who were admitted to Ankara D??kap? Y?ld?r?m Beyaz?t Education and Research Hospital Psychiatry Clinic, 31 healthy volunteers who had never used alcohol and 33 social drinkers were evaluated. For all groups, BSU and Craving Beliefs Questionnaire (CBQ, for the patient groups, Beck Anxiety Inventory (BAI, Clinical Institute Withdrawal Assessment (CIWA, Dysfunctional Attitudes Questionnaire (DAS and Automatic Thoughts Questionnaire (ATQ were used as the assessment tools. The correlations and differences between the questionnaires were studied. Results: Mean age of the addicted patients, healthy controls and social drinkers were 42,3± 7,0, 33,5± 9,9 and 33,2± 8,9, respectively. In patient group, mean BSU score was 46,4 ± 21,2. For alcohol addicts, internal reliability of BSU was found to be adequate (Cronbach alfa=0.91 and item-total score correlations were between 0.33 and 0.69. Basic component analysis showed one basic factor. A positive correlation has been found between BSU and CBQ, and ATQ scores. No correlations have been found between total and subscale scores of DAS and total scores of CIWA, BAI and BSU. In evaluation of validity, BSU mean scores of alcohol addicts were found to be significantly higher than healthy controls and social drinkers. Conclusion: Our findings support that Turkish version of BSU is an adequate tool that can be used to evaluate alcohol addicted patients` cognitive believes about alcohol use
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' ?. 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 -- 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.)
Empirical rainfall thresholds are tools to forecast the possible occurrence of rainfall-induced shallow landslides. Accurate prediction of landslide occurrence requires reliable thresholds, which need to be properly validated before their use in operational warning systems. We exploited a catalogue of 200 rainfall conditions that have resulted in at least 223 shallow landslides in Sicily, southern Italy, in the 11-year period 2002-2011, to determine regional event duration-cumulated event rainfall (ED) thresholds for shallow landslide occurrence. We computed ED thresholds for different exceedance probability levels and determined the uncertainty associated to the thresholds using a consolidated bootstrap nonparametric technique. We further determined subregional thresholds, and we studied the role of lithology and seasonal periods in the initiation of shallow landslides in Sicily. Next, we validated the regional rainfall thresholds using 29 rainfall conditions that have resulted in 42 shallow landslides in Sicily in 2012. We based the validation on contingency tables, skill scores, and a receiver operating characteristic (ROC) analysis for thresholds at different exceedance probability levels, from 1% to 50%. Validation of rainfall thresholds is hampered by lack of information on landslide occurrence. Therefore, we considered the effects of variations in the contingencies and the skill scores caused by lack of information. Based on the results obtained, we propose a general methodology for the objective identification of a threshold that provides an optimal balance between maximization of correct predictions and minimization of incorrect predictions, including missed and false alarms. We expect that the methodology will increase the reliability of rainfall thresholds, fostering the operational use of validated rainfall thresholds in operational early warning system for regional shallow landslide forecasting.

Full Text Available Objective: Any disease specific Health Related Quality of Life Instrument for Chronic Heart Failure (CHF is lacking in Turkey. The aim of this study is to adapt the Chronic Heart Failure Questionnaire (CHQ into Turkish and probe the reliability and validity of this questionnaire. Methods: There are four dimensions of this 20 items scale. These dimensions are: dyspnea (5 items, fatigue (4 items, emotional status (7 items and mastery (4 items. Response options were evaluated using a 7 -point Likert type scale. Quality of life (QOL improves as the score increases. A total of 205 CHF patients hospitalized in the Department of Cardiology of Ege University hospital were enrolled in this study. The CHQ was applied to the patients twice with a wash-out period of 15 days. Confirmatory approach was used during the reliability and validity analysis. Cronbach alpha test was used for the reliability analysis. Confirmatory factor analysis (CFA was used for the construct validity testing. NYHA classification for testing the criterion validity; SF-36 and WHOQOL-100 General Health and QOL facet for convergent validity testing of the Turkish version of the CHQ were used. Responsiveness to change was evaluated by Effect Size analysis by using test-retest data. Results: The range of Cronbach alpha values is 0.72-0.94. A considerable ceiling and floor effects were observed for the dyspnea dimension of the scale but no problematic items were observed for the entire scale. The CFA results supported the original four factors scale structure. Criterion and construct validity rebuts were satisfactory. Effect sizes obtained among dimensions of the CHQ were between 0.13 and 0.56. Conclusion: Overall results revealed that Turkish version of the CHQ is a reliable and valid instrument to be used for the evaluation of CHF patients.
Full Text Available 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 physical and 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.

Full Text Available AimIllness may impact the positivity of a person’s mindset. However, patients with visual impairment, such as uveitis, may struggle to complete questionnaires. The aim of this study was to validate a brief and simple measure of positive mindset in people with uveitis.MethodThis study was a cross-sectional survey of 200 people with uveitis. The Positive Mindset Index (PMI questionnaire uses six items to measure a patient’s happiness, confidence, sense of being in control, stability, motivation, and optimism. ResultsExploratory factor analysis revealed a well-fitting unidimensional factor structure (KMO = .898, with strong factor loadings (from .616 to .721 and excellent internal reliability (Cronbach’s ? = .926. The PMI showed strong concurrent validity with the mental health subscale of the SF-36 (r = .789 and good construct validity relative to the physical health subscale of the SF-36 (r = .468. Excellent test-retest reliability was seen (r = .806. Patients taking 10 mg or more corticosteroid daily had significantly lower PMI scores than those on a lower dose or no dose (t (170 = 2.298, p < .023.ConclusionThe PMI has good face validity and sound psychometric properties. It is a very brief and simple measure, thus user-friendly for patients with visual impairment, as well as researchers and others using the scale.

Objective. Sasang typology is a traditional Korean medicine based on the biopsychosocial perspectives of Neo-Confucianism and utilizes medical herbs and acupuncture for type-specific treatment. This study was designed to develop and validate the Sasang Personality Questionnaire (SPQ) for future use in the assessment of personality based on Sasang typology. Design and Methods. We selected questionnaire items using internal consistency analysis and examined construct validity with explorative factor analysis using 245 healthy participants. Test-retest reliability as well as convergent validity were examined. Results. The 14-item SPQ showed acceptable internal consistency (Cronbach's alpha = .817) and test-retest reliability (r = .837). Three extracted subscales, SPQ-behavior, SPQ-emotionality, and SPQ-cognition, were found, explaining 55.77% of the total variance. The SPQ significantly correlated with Temperament and Character Inventory novelty seeking (r = .462), harm avoidance (r = -.390), and NEO Personality Inventory extraversion (r = .629). The SPQ score of the So-Eum (24.43 ± 4.93), Tae-Eum (27.33 ± 5.88), and So-Yang (30.90 ± 5.23) types were significantly different from each other (P < .01). Conclusion. Current results demonstrated the reliability and validity of the SPQ and its subscales that can be utilized as an objective instrument for conducting personalized medicine research incorporating the biopsychosocial perspective.

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 (sectionmade 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.

Full Text Available The aim of this study was to develop and validate a questionnaire that measures the effectiveness of communication during organisational change interventions. A draft questionnaire was completed by a sample of convenience comprising 521 participants. The questionnaire contained 109 items in question format with a Likert-type response scale anchored at the extreme ends. The data was factor analysed and an iterative item analysis was executed. The results yielded a single scale with a Cronbach Alpha coefficient of 0,99. It is concluded, therefore, that the conceptualised domain of “communicating-for-change"? could be measured successfully through the use of the instrument developed in this study.

OBJECTIVE:: Persistent postoperative pain is an acknowledged entity that reduces daily activities. Evaluation of the post-thoracotomy pain syndrome (PTPS) is often measured using traditional pain scales without in-depth questions on pain impairment. Thus, the purpose was to create a procedure-specific questionnaire for assessment of functional impairment due to PTPS. METHODS:: Activities were obtained from the literature supplemented by interviews with patients and surgeons. The questionnaire was validated using the Rasch model in order to describe an underlying pain impairment scale. RESULTS:: Four of 17 questions were redundant. The remaining 13 questions from low to intensive activity described functional impairment following persistent pain from thoracotomy and video-assisted thoracic surgery (VATS). No evidence for differential item functioning for gender, age or differences between open or VATS, were found. A generalized log-linear Rasch model including local dependence was constructed. Though local dependence influenced reliability, the test-retest reliability estimated under the log-linear Rasch model was high (0.88-0.96). Correlation with items from the Disability of the Arm, Shoulder and Hand (quick) questionnaire supported validity (?=0.46, P

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.
The Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire was developed directly from rheumatoid arthritis (RA) patients in the United Kingdom and the Netherlands to measure quality of life (QoL). Since then, it has become widely used in clinical studies and trials and has been adapted for use in 24 languages. The objective was to develop and validate 11 additional language versions of the RAQoL in US English, Mexican Spanish, Argentinean Spanish, Belgian French, Belgian Flemish, French, Romanian, Czech, Slovakian, Polish and Russian. The language adaptation and validation required three stages: translation, cognitive debriefing interviews and validation survey. The translation process involved a dual-panel methodology (bilingual panel followed by a lay panel). The validation survey tested the psychometric properties of the new scales and included either the Nottingham Health Profile (NHP) or the Health Assessment Questionnaire (HAQ) as comparators. Internal consistency of the new language versions ranged from 0.90 to 0.97 and test-retest reliability from 0.85 to 0.99. RAQoL scores correlated as expected with the HAQ. Correlations with NHP sections were as expected: highest with energy level, pain and physical mobility and lowest with emotional reactions, sleep disturbance, and social isolation. The adaptations exhibited construct validity in their ability to distinguish subgroups of RA patients varying by perceived disease severity and general health. The new language versions of the RAQoL meet the high psychometric standards of the original UK English version. The new adaptations represent valid and reliable tools for measuring QoL in international clinical trials involving RA patients. PMID:25270915

INTRODUCTION: The Toronto Extremity Salvage Score (TESS) questionnaire is a self-administered questionnaire designed to assess physical disability in patients having undergone surgery of the extremities. The aim of this study was to validate a Danish translation of the TESS. MATERIAL AND METHODS: The TESS was translated according to international guidelines. A total of 22 consecutive patients attending the regular outpatient control programme were recruited for the study. To test their understanding of the questionnaires, they were asked to describe the meaning of five randomly selected questions from the TESS. The psychometric properties of the Danish version of TESS were tested for validity and reliability. To assess the test-retest reliability, the patients filled in an extra TESS questionnaire one week after they had completed the first one. RESULTS: Patients showed good understanding of the questionnaire. There was a good internal consistency for both the upper and lower questionnaire measured by Cronbach's alpha. A Bland-Altman plot showed acceptable limits of agreement for both questionnaires in the test-retest. There was also good intraclass correlation coefficients for both questionnaires. The validity expressed as Spearman's rank correlation coefficient comparing the TESS with the QLQ-C30 was 0.89 and 0.90 for the questionnaire on upper and lower extremities, respectively. CONCLUSION: The psychometric properties of the Danish TESS showed good validity and reliability. FUNDING: not relevant. TRIAL REGISTRATION: not relevant.

Full Text Available The present paper reports the results of the Spanish adaptation and va- lidation of the Emotional Style Questionnaire conducted with a sample of Venezuelan university students. The original 56 items scale (Roger & Najarian, 1989; Roger & Nesshoever, 1987 measured four dimensions of emotional styles: rumination, emotional inhibition, aggresion control and benign control. However, based on the resivion of the scales, Roger, Guarino and Olason (2000 propused a shorter version of 39 items, where only the rumination and emotional inhibition scales were maintained. The Spanish version of this scale, jointly with other personality questionnaires and health vmeasures, was administered to a sample of 419 Venezuelan university students and results showed the structure of the scale to be nearly identical to the English version, with adequate internal consistency. The concurrent and predictive validation study supports the theoretical structure for each dimension.

Oral health-related quality of life (OHRQoL) is an important aspect of health outcomes and its assessment should be made using validated instruments. The psychosocial impact of dental aesthetics questionnaire (PIDAQ) is an OHRQoL instrument that assesses the psychosocial impact of dental aesthetics was developed and validated for use on young adults. The aim of the present study was to assess the reliability, validity, and applicability of the PIDAQ for young adults in Brazil. After translation and cross-cultural adaptation, the questionnaire was completed by 245 individuals (124 males and 121 females) aged 18-30 years from the city of Belo Horizonte, Brazil. In order to test discriminant validity, the subjects were examined for the presence or absence of malocclusion based on the dental aesthetic index criteria. Dental examinations were carried out by a previously calibrated examiner [weighted kappa = 0.64-1.00, intraclass correlation coefficient (ICC) = 0.78-1.00]. Internal consistency measured by Cronbach's alpha of the subscales was between 0.75 and 0.91 and test-retest reliability was assessed using the ICC, which ranged from 0.89 to 0.99 for dental self-confidence and social impact, thereby revealing satisfactory reliability. Discriminant validity revealed that subjects without malocclusion had different PIDAQ scores when compared with those with malocclusion. The results suggest that the Brazilian version of the PIDAQ has satisfactory psychometric properties and is thus applicable to young adults in Brazil. Further research is needed to assess these properties in population studies. PMID:20713456

Population screening may harm quality of life (QoL), and traditional health-related QoL tools could be inadequate to evaluate this risk. Two global and generic QoL instruments were developed for studying the QoL consequences of screening (SCREENQOL), and QoL variation in a normal population (SEQOL). SCREENQOL and SEQOL (Self-Evaluation of Quality of Life Questionnaire) are self-administered questionnaires with items rated on 5-point Likert scales. SCREENQOL consists of 21 items measuring QoL across 6 different dimensions based upon validated QoL questionnaires. SEQOL consists of 317 items measuring QoL across 8 different dimensions, based on an integrative theory of QoL, a theoretical framework from a Danish QoL survey involving 7,222 persons 31 to 33 years old. For further validation, SEQOL and SCREENQOL were sent to 2,460 persons 18 to 88 years old randomly selected from the Danish Central Person Register together with Nottingham Health Profile (NHP) and Sickness Impact Profile (SIP). For SCREENQOL and SEQOL, test-retest reliability correlation was both >0.8, Cronbach's alpha was 0.65 and 0.75, correlation (r) to NHP was 0.67 and 0.49, to SIP 0.46 and 0.27, respectively (p <0.05). Adjustment for health status made the correlation to SIP stronger among the sick (r = 0.68 and 0.41, respectively). For SCREENQOL and SEQOL, 61 and 111 respondents were needed to detect 3% difference in QoL. SCREENQOL and SEQOL are both valid as they show high levels of reliability, sensitivity, and consistency.

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.

BackgroundSpanish is one of the five most spoken languages in the world. There is currently no published Spanish version of the Örebro Musculoskeletal Pain Questionnaire (OMPQ). The aim of the present study is to describe the process of translating the OMPQ into Spanish and to perform an analysis of reliability, internal structure, internal consistency and concurrent criterion-related validity.MethodsDesign: Translation and psychometric testing. Procedure: Two independent translators translated the OMPQ into Spanish. From both translations a consensus version was achieved. A backward translation was made to verify and resolve any semantic or conceptual problems. A total of 104 patients (67 men/37 women) with a mean age of 53.48 (±11.63), suffering from chronic musculoskeletal disorders, twice completed a Spanish version of the OMPQ. Statistical analysis was performed to evaluate the reliability, the internal structure, internal consistency and concurrent criterion-related validity with reference to the gold standard questionnaire SF-12v2.ResultsAll variables except ¿Coping¿ showed a rate above 0.85 on reliability. The internal structure calculation through exploratory factor analysis indicated that 75.2% of the variance can be explained with six components with an eigenvalue higher than 1 and 52.1% with only three components higher than 10% of variance explained. In the concurrent criterion-related validity, several significant correlations were seen close to 0.6, exceeding that value in the correlation between general health and total value of the OMPQ.ConclusionsThe Spanish version of the screening questionnaire OMPQ can be used to identify Spanish patients with musculoskeletal pain at risk of developing a chronic disability.

Overexcitability corresponds to an overall response to stimulations in 5 domains: psychomotor, sensual, intellectual, imaginational, and emotional. The aim of this study was to develop a French version of the Overexcitability Questionnaire 2 (OEQ2) and to expand its psychometric properties. Two studies were conducted: one with a sample of 474 adolescents and another with a sample of 436 adults. Internal consistency, factorial structure, and validity (correlations with intelligence, personality, and alexithymia) were examined. The French OEQ2 showed satisfactory psychometric properties, thus advocating for its use in further research on overexcitability and in clinical practice. PMID:25090583

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 QUFW94ified 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.
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.

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.
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.

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 influence of an individuals' belief in their ability to resist drinking alcohol has recognised importance in understanding the pattern of drinking behaviours among Caucasian samples. Measures used to investigate this construct, such as the drinking refusal self-efficacy questionnaire-revised (DRSEQ-R; [Oei, T. P. S., Hasking, P. A., & Young, R. M. (2005). Drinking refusal self-efficacy questionnaire-revised (DRSEQ-R): A new factor structure with confirmatory factor analysis. Drug and Alcohol Dependence, 78, 297-307.]) have been widely used and have established psychometric properties. However, the exploration of the utility of this questionnaire with samples of different ethnicity, religion and living in different countries remains scarce. In the current study, Arab Muslim samples living in the United Arab Emirates and Oman (n=356) and Asian predominately Muslim samples living in Malaysia and Indonesia (n=256) were used. Exploratory and confirmatory factor analysis demonstrated that the DRSEQ-R has a three factor structure. Internal consistency ranged from alpha .96 to alpha .86 and validity was good. This study offers evidence of the utility of this measure with Arab and Asian samples. PMID:19481874

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.

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.

We compared the administration of the 9-item Patient Health Questionnaire (PHQ-9) to assess depressive symptoms using interactive voice response (IVR) technology with the method of administration using paper-and-pencil. Data were collected from 51 veterans participating in an 8-week randomized controlled trial of an illness management programme for heart failure. To counter possible bias in answering questions via IVR technology, the anchoring responses of the PHQ-9 questionnaire were reversed so that lower numbers corresponded to more severe depression. The mean for the pencil-and-paper administered PHQ-9 was 4.1 (SD = 4.5) and the mean for IVR administration was 2.8 (SD = 3.1). The internal consistency (Cronbach's alpha) of the PHQ-9 was 0.76 for IVR administration and 0.82 for paper administration. The intraclass correlation coefficient for the two modes of administration was 0.65, indicating moderate agreement. IVR administration of the PHQ-9 produces similar results to pencil-and-paper administration, but the former is not as sensitive to higher levels of depressive symptom severity. This suggests that a lower threshold for probable depression is warranted when assessing depressive symptoms with IVR. PMID:22933480

Full Text Available Abstract Background A previous review suggested that the MacNew Quality of Life Questionnaire was the most appropriate disease-specific measure of health-related quality of life among people with ischaemic heart disease. However, there is ambiguity about the allocation of items to the three factors underlying the MacNew and the factor structure has not been confirmed previously among the people in the UK. Methods The MacNew Questionnaire and the SF-36 were administered to 117 newly admitted patients to a tertiary referral centre in Northern Ireland. All patients had been diagnosed with ischaemic heart disease. Results A confirmatory factor analysis was conducted on the factor structure of the MacNew and the model was found to be an inadequate fit of the data. A quantitative and qualitative analysis of the items suggested that a five factor solution was more appropriate and this was validated by confirmatory factor analysis. This new structure also displayed strong evidence of concurrent validity when compared to the SF-36. Conclusion We recommend that researchers should submit scores obtained from items on the MacNew to secondary analyses after being grouped according to the factor structure proposed in this paper, in order to explore further the most appropriate grouping of items.

The Revised Fibromyalgia Impact Questionnaire (FIQR) attempts to address the limitations of the Fibromyalgia Impact Questionnaire (FIQ). As there is no Turkish version of the FIQR available, we aimed to investigate the validity and reliability of a Turkish translation of the FIQR in Turkish female fibromyalgia (FM) patients. After translating the FIQR into Turkish, it was administered to 87 female patients with FM. All of the patients filled out the questionnaire together with a Turkish version of the FIQ, hospital anxiety and depression scales (HADS), short form-36 (SF-36). The tender-point count (TPC) was also calculated from tender points identified by thumb palpation. One week later, FM patients filled out the Turkish FIQR at their second visit. The test-retest reliability of the Turkish FIQR questions ranged from 0.714 to 0.898. The test and retest reliability of total FIQR score was 0.835. Cronbach's alpha was 0.89 for FIQR visit 1 (the first assessment) and 0.91 for FIQR visit 2 (the second assessment), indicating acceptable levels of internal consistency for both assessments. The total scores of the FIQR and FIQ were significantly correlated (r?=?0.87, P?scores and the FIQ, the HADS and the subscales of the SF-36 (FIQR total versus SF-36 physical component score and mental component score were r?=?-0.63, P?health status in FM, showing sufficient reliability and construct validity. It may be utilized for both clinical practice and research use in the Turkish-speaking population in place of FIQ, since its Turkish version has problems in the wording, omissions, concepts, and scoring from the original FIQ.

Full Text Available Aim: The goal of this research is to evaluate the psychometric qualities of the Polish version of the SCL-27-plus questionnaire in terms of its five factor structure, internal consistency and theoretical accuracy. Method: A total of 1.350 persons of which 62% were males, participated in the study. 651 persons were tested with a paper version, 699 subjects received an electronic version of the questionnaire. 336 (tested with the paper version were patients with diagnosed psychiatric disorders. Paper version participants also filled out the General Health Questionnaire (GHQ-28. Results: Confirmatory factor analysis validated the five factor structure of SCL-27-plus when some errors terms within subscales are allowed to correlate (Depending on the sample: 1.64 ? ?2/df ? 2.46; 0.05 ? RMSEA ? 0.06; 0.91 ? CFI ? 0.95. Cronbach’s Alpha reliability measures for the Global Severity Index was 0.90 to 0.92 and for the particular subscales 0.71 to 0.88. The GSI and symptom subscales for SCL-27-plus correlated with their equivalences in the GHQ-28 moderately to highly (r = 0.38 to 0.68. Strong differences occurred between the “clinical” and “non-clinical” groups in the levels of general and specific symptoms (Cohen’s d from 0.42 to 1.15. Conclusions: The Polish version of the SCL-27-plus questionnaire demonstrates good psychometric qualities. It can be used to measure the general intensity of psychopathological impairment as well as the specific subscales.
Angina pectoris causes substantial psychological and functional disability and adversely effects health-related quality of life, particularly in women. Studies of cardiac disease-specific quality of life in women with coronary artery disease and angina are limited because little reliability and validity data for these instruments exist for women. Therefore, the purpose of this study was to examine reliability and validity of the Seattle Angina Questionnaire (SAQ), a cardiac disease-related quality-of-life measure, in a sample of women with chronic stable angina. A secondary analysis was performed on SAQ data from 175 women with a confirmed diagnosis of CAD and angina pectoris. The majority of the women were older, white, living with their spouse, had a previous acute myocardial infarction, and had undergone revascularization. The Cronbach ? was used to assess reliability of the SAQ’s five subscales, and factor analysis was used to assess the SAQ’s validity. Results suggest that the SAQ is a reliable and valid quality-of-life measure in women with CAD. The physical limitations subscale factored into two separate factors, suggesting that the subscale measures two domains of physical function: self-care and exercise tolerance/mobility. Future research is needed to determine whether examining different combinations of SAQ items might provide a more sensitive assessment of cardiac disease-specific quality of life in women.

The purpose of this paper is to evaluate its criterion and construct validity. Methods Data from 10 different primary care studies have been used. Criterion validity was assessed by comparing the 4DSQ scores with clinical diagnoses, the GPs' diagnosis of any psychosocial problem for Distress, standardised psychiatric diagnoses for Depression and Anxiety, and GPs' suspicion of somatization for Somatization. ROC analyses and logistic regression analyses were used to examine the associations. Construct validity was evaluated by investigating the inter-correlations between the scales, the factorial structure, the associations with other symptom questionnaires, and the associations with stress, personality and social functioning. The factorial structure of the 4DSQ was assessed through confirmatory factor analysis (CFA. The associations with other questionnaires were assessed with Pearson correlations and regression analyses. Results Regarding criterion validity, the Distress scale was associated with any psychosocial diagnosis (area under the ROC curve [AUC] 0.79, the Depression scale was associated with major depression (AUC = 0.83, the Anxiety scale was associated with anxiety disorder (AUC = 0.66, and the Somatization scale was associated with the GPs' suspicion of somatization (AUC = 0.65. Regarding the construct validity, the 4DSQ scales appeared to have considerable inter-correlations (r = 0.35-0.71. However, 30–40% of the variance of each scale was unique for that scale. CFA confirmed the 4-factor structure with a comparative fit index (CFI of 0.92. The 4DSQ scales correlated with most other questionnaires measuring corresponding constructs. However, the 4DSQ Distress scale appeared to correlate with some other depression scales more than the 4DSQ Depression scale. Measures of stress (i.e. life events, psychosocial problems, and work stress were mainly associated with Distress, while Distress, in turn, was mainly associated with psychosocial dysfunctioning, including sick leave. Conclusion The 4DSQ seems to be a valid self-report questionnaire to measure distress, depression, anxiety and somatization in primary care patients. The 4DSQ Distress scale appears to measure the most general, most common, expression of psychological problems.

Full Text Available Abstract Background Currently, no validated instruments are available to measure the health status of Bangladeshi patients with fibromyalgia (FM. The aims of this study were to cross-culturally adapt the modified Fibromyalgia Impact Questionnaire (FIQ into Bengali (B-FIQ and to test its validity and reliability in Bangladeshi patients with FM. Methods The FIQ was translated following cross-cultural adaptation guidelines and pretested in 30 female patients with FM. Next, the adapted B-FIQ was physician-administered to 102 consecutive female FM patients together with the Health Assessment Questionnaire (HAQ, selected subscales of the SF-36, and visual analog scales for current clinical symptoms. A tender point count (TPC was performed by an experienced rheumatologist. Forty randomly selected patients completed the B-FIQ again after 7?days. Two control groups of 50 healthy people and 50 rheumatoid arthritis (RA patients also completed the B-FIQ. Results For the final B-FIQ, five physical function sub-items were replaced with culturally appropriate equivalents. Internal consistency was adequate for both the 11-item physical function subscale (??=?0.73 and the total scale (??=?0.83. With exception of the physical function subscale, expected correlations were generally observed between the B-FIQ items and selected subscales of the SF-36, HAQ, clinical symptoms, and TPC. The B-FIQ was able to discriminate between FM patients and healthy controls and between FM patients and RA patients. Test-retest reliability was adequate for the physical function subscale (r?=?0.86 and individual items (r?=?0.73-0.86, except anxiety (r?=?0.27 and morning tiredness (r?=?0.64. Conclusion This study supports the reliability and validity of the B-FIQ as a measure of functional disability and health status in Bangladeshi women with FM.

Full Text Available Abstract Background Treating anemia associated with chemotherapy and many cancers is often necessary. However, patient satisfaction with anemia treatment is limited by the lack of validated instruments. We developed and validated a new treatment-specific patient satisfaction instrument: the Patient Satisfaction Questionnaire for Anemia Treatment (PSQ-An. Treatment burden and overall satisfaction scales were designed for ease of use in clinical practice. Methods 312 cancer patients (141 breast, 69 gynecological, and 102 non-small cell lung were targeted to complete the PSQ-An at 4 week intervals. Data from weeks 5 and 9 were analyzed. Patients also completed the MOS SF-36 Global Health assessment and questions concerning resources devoted to anemia treatment. Item reduction used endorsement rates, floor/ceiling effects, and item-item correlations. Factor analysis identified meaningful subscales. Test-retest reliability was assessed. Construct validity was tested, using Pearson's correlations, by comparing subscale scores to Global Health, hemoglobin levels, and resources devoted to anemia treatment. Results The overall response rate was 92.9% (264/284 at week 5. Most (84.2% of the patients were female, and the mean (SD age was 60.2 (± 11.8 years. Two distinct subscales were identified measuring treatment burden (7 items and overall satisfaction (2 items. Test-retest reliability was examined (ICC: 0.45–0.67; both were internally consistent (alpha = 0.83. Both subscales exhibited convergent and divergent validity with independent measures of health. ANOVA results indicated that the PSQ-An Satisfaction subscale discriminated between 5 levels of MOS SF-36 Global Health (P = 0.006. Conclusion The PSQ-An is a validated, treatment-specific instrument for measuring satisfaction with anemia treatment for cancer patients. PSQ-An subscales reflect the burden of injection anemia treatment on cancer patients and their assessment of the overall treatment value.
Full Text Available Abstract Background Studies exploring the role of diet during pregnancy are still scarce, in part due to the complexity of measuring diet and to the lack of valid instruments. The aim of this study was to examine the reproducibility and validity (against biochemical biomarkers of a semi-quantitative food frequency questionnaire (FFQ in pregnant women. Methods Participants were 740 pregnant women from a population-based birth cohort study in Valencia (INMA Study. We compared nutrient and food intakes from FFQs estimated for two periods of pregnancy (reproducibility, and compared energy-adjusted intake of several carotenoids, folate, vitamin B12, vitamin C and ?-tocopherol of the FFQ in the first trimester with their concentration in blood specimens (validity. Results Significant correlations for reproducibility were found for major food groups and nutrients but not for lycopene (r=0.06; the average correlation coefficients for daily intake were 0.51 for food groups and 0.61 for nutrients. For validity, statistically significant correlations were observed for vitamin C (0.18, ?-carotene (0.32, ?-carotene (0.22, lutein-zeaxantin (0.29 and ?-cryptoxantin(0.26; non-significant correlations were observed for retinol, lycopene, ?-tocopherol, vitamin B12 and folate (r?0.12. When dietary supplement use was considered, correlations were substantially improved for folate (0.53 and to a lesser extent for vitamin B12 (0.12 and vitamin C (0.20. Conclusion This study supports that the FFQ has a good reproducibility for nutrient and food intake, and can provide a valid estimate of several important nutrients during pregnancy.
Full Text Available Abstract Background The International Physical Activity Questionnaire - Short Form (IPAQ-SF has been recommended as a cost-effective method to assess physical activity. Several studies validating the IPAQ-SF have been conducted with differing results, but no systematic review of these studies has been reported. Methods The keywords "IPAQ", "validation", and "validity" were searched in PubMed and Scopus. Studies published in English that validated the IPAQ-SF against an objective physical activity measuring device, doubly labeled water, or an objective fitness measure were included. Results Twenty-three validation studies were included in this review. There was a great deal of variability in the methods used across studies, but the results were largely similar. Correlations between the total physical activity level measured by the IPAQ-SF and objective standards ranged from 0.09 to 0.39; none reached the minimal acceptable standard in the literature (0.50 for objective activity measuring devices, 0.40 for fitness measures. Correlations between sections of the IPAQ-SF for vigorous activity or moderate activity level/walking and an objective standard showed even greater variability (-0.18 to 0.76, yet several reached the minimal acceptable standard. Only six studies provided comparisons between physical activity levels derived from the IPAQ-SF and those obtained from objective criterion. In most studies the IPAQ-SF overestimated physical activity level by 36 to 173 percent; one study underestimated by 28 percent. Conclusions The correlation between the IPAQ-SF and objective measures of activity or fitness in the large majority of studies was lower than the acceptable standard. Furthermore, the IPAQ-SF typically overestimated physical activity as measured by objective criterion by an average of 84 percent. Hence, the evidence to support the use of the IPAQ-SF as an indicator of relative or absolute physical activity is weak.

Full Text Available Background: A 50-item self-administered food frequency questionnaire (FFQ was developed for French adults, to assess the intake of energy, 10 macronutrients, 11 vitamins, and 11 minerals, and to be used in the context of a medical consultation. Objective: To assess the repeatability and relative validity of this FFQ compared to a 7-day diet record (7-DR. Design: A total of 54 and 100 French adults were included in the repeatability and validation studies, respectively. Repeatability was assessed using two FFQs, the second carried out 3 weeks after the first. In the validation study, subjects first completed the FFQ, then the 7-DR the following week. Energy and nutrient intakes were compared using Pearson correlation. The degree of misclassification by the FFQ, compared to the 7-DR, was calculated by a contingency table of quintiles. Bland–Altman plots assessed the correlation between FFQ and 7-DR across the intake range. Results: Repeatability for intake, explored by Pearson correlation, was 0.62–0.90 (median: 0.81. Relative validity, as determined by Pearson correlation for the nutrient intake derived from the FFQ and 7-DR, was 0.36–0.80 (0.64. The FFQ tended to report higher fiber and micronutrient intake than 7-DR. Misclassification into opposite quintiles ranged 0–6% (1%, whereas classification into same or adjacent quintiles ranged 59–83% (74%. Bland–Altman plots showed good agreement for most nutrients across the range of intake. Conclusion: This new FFQ showed a high repeatability and good relative validity, and thanks to its short length, should be a useful tool for rapidly evaluating the nutrient intake of French adults.
PURPOSE: Measuring and developing a safe culture in health care is a focus point in creating highly reliable organizations being successful in avoiding patient safety incidents where these could normally be expected. Questionnaires can be used to capture a snapshot of an employee's perceptions of patient safety culture. A commonly used instrument to measure safety climate is the Safety Attitudes Questionnaire (SAQ). The purpose of this study was to adapt the SAQ for use in Danish hospitals, assess its construct validity and reliability, and present benchmark data. MATERIALS AND METHODS: The SAQ was translated and adapted for the Danish setting (SAQ-DK). The SAQ-DK was distributed to 1,263 staff members from 31 in- and outpatient units (clinical areas) across five somatic and one psychiatric hospitals through meeting administration, hand delivery, and mailing. Construct validity and reliability were tested in a cross-sectional study. Goodness-of-fit indices from confirmatory factor analysis were reported along with inter-item correlations, Cronbach's alpha (?), and item and subscale scores. RESULTS: Participation was 73.2% (N=925) of invited health care workers. Goodness-of-fit indices from the confirmatory factor analysis showed: c(2)=1496.76, P<0.001, CFI 0.901, RMSEA (90% CI) 0.053 (0.050-0056), Probability RMSEA (p close)=0.057. Inter-scale correlations between the factors showed moderate-to-high correlations. The scale stress recognition had significant negative correlations with each of the other scales. Questionnaire reliability was high, (?=0.89), and scale reliability ranged from ?=0.70 to ?=0.86 for the six scales. Proportions of participants with a positive attitude to each of the six SAQ scales did not differ between the somatic and psychiatric health care staff. Substantial variability at the unit level in all six scale mean scores was found within the somatic and the psychiatric samples. CONCLUSION: SAQ-DK showed good construct validity and internal consistency reliability. SAQ-DK is potentially auseful tool for evaluating perceptions of patient safety culture in Danish hospitals.

To accurately examine associations of physical activity (PA) with disease outcomes, a valid method of assessing free-living activity is required. We examined the validity of a brief PA questionnaire (PAQ) used in the European Prospective Investigation into Cancer and Nutrition (EPIC). PA energy expenditure (PAEE) and time spent in moderate and vigorous physical activity (MVPA) was measured in 1,941 healthy individuals from 10 European countries using individually-calibrated combined heart-rate and movement sensing. Participants also completed the short EPIC-PAQ, which refers to past year's activity. Pearson (r) and Spearman (?) correlation coefficients were calculated for each country, and random effects meta-analysis was used to calculate the combined correlation across countries to estimate the validity of two previously- and one newly-derived ordered, categorical PA indices ("Cambridge index", "total PA index", and "recreational index") that categorized individuals as inactive, moderately inactive, moderately active, or active. The strongest associations with PAEE and MVPA were observed for the Cambridge index (r = 0.33 and r = 0.25, respectively). No significant heterogeneity by country was observed for this index (I(2) = 36.3%, P = 0.12; I(2) = 0.0%, P = 0.85), whereas heterogeneity was suggested for other indices (I(2) > 48%, P 47%, P

Objective: The objective of this study was to extend the Consequences of Screening (COS) Questionnaire for use in a lung cancer screening by testing for comprehension, content coverage, dimensionality, and reliability. Methods: In interviews, the suitability, content coverage, and relevance of the COS were tested on participants in a lung cancer screening program. The results were thematically analyzed to identify the key consequences of abnormal and false-positive screening results. Item Response Theory and Classical Test Theory were used to analyze data. Dimensionality, objectivity, and reliability were established by item analysis, examining the fit between item responses and Rasch models. Results: Eight themes specifically relevant for participants in lung cancer screening results were identified: “self-blame,” “focus on symptoms,” “stigmatization,” “introvert,” “harm of smoking,” “impulsivity,” “empathy,” and “regretful of still smoking.” Altogether, 26 new items for part I and 16 new itemsfor part II were generated.These themes were confirmed to fit a partial-credit Rasch model measuring different constructs including several of the new items. Conclusion: In conclusion, the reliability and the dimensionality of a condition-specific measure with high content validity for persons having abnormal or false-positive lung cancer screening results have been demonstrated. This new questionnaire called Consequences of Screening in Lung Cancer (COS-LC) covers in two parts the psychosocial experience in lung cancer screening. Part I: “anxiety,” “behavior,” “dejection,” “sleep,” “selfblame,” “focus on airway symptoms,” “stigmatization,” “introvert,” and “harm of smoking.” Part II: “calm/relax,” “social network,” “existential values,” “impulsivity,” “empathy,” and “regretful of still smoking.” Keywords: lung cancer, psychometrics, public health, questionnaire development, secondary prevention.

The Dutch Eating Behavior Questionnaire (DEBQ) was developed to measure eating styles that may contribute to or attenuate the development of overweight. It comprises three scales that measure emotional, external and restrained eating. The main goal of this study is to evaluate the internal structure of the Spanish version of the DEBQ using updated psychometric techniques in a sample of women. A sample of 647 Spanish females answered the questionnaire. Both exploratory structural equation modeling and confirmatory factor analysis were used to evaluate the factor structure of the DEBQ. Reliabilities were estimated with Cronbach's alpha. The relations between the subscales of the DEBQ and age, BMI, and scores on the Eating Attitude Test-26 (EAT) and the Restrained Scale-Revised (RS) were computed with Pearson correlations. Results showed that the internal structure was similar to the theoretical proposal, although items associated with boredom and idleness presented cross-loading problems. The reliability estimates were satisfactory. The Emotional and External Eating factors correlated with the BMI, and External Eating was negatively correlated with age. The Restraint factor of the DEBQ showed significant relationships with scales of the EAT-26 and RS. The dimensional validity of the DEBQ is reproduced in a Spanish sample, and the DEBQ seems to be an effective instrument for research in Spanish females. Minor modifications to the DEBQ are recommended. PMID:24177441

The aim of this study was to translate the Breast Evaluation Questionnaire (BEQ 55) into Portuguese, and culturally adapt and validate the translation for use in Brazil. METHODS: Two translations, two revisions by a multidisciplinary group, and two back translations of the questionnaire were performed. Cultural adaptation was performed by applying the questionnaire to groups of 20 patients from the plastic surgery outpatient clinic. The questionnaire included relevant modifications for better understanding of the questions. To test the questionnaire's reproducibility and validity, 20 patients were interviewed on two separate occasions. On the first occasion, they were interviewed by different interviewers, and on the second occasion (after 7 days and after 14 days), by only one. In addition, the Short-Form 36 was applied during the first interview. RESULTS: During cultural adaptation, questions were modified to facilitate the patients' understanding. A new group was tested to confirm that items were understood. Internal consistency of the questionnaire ranged between 0.931 and 0.936. The interobserver reproducibility coefficient was 0.962, and the intraobserver reproducibility coefficient was 0.919. Only the domains of the SF-36 regarding functional capacity, general health status, and emotional aspects correlated with the total score of the BEQ 55. CONCLUSIONS: The BEQ 55 questionnaire was successfully translated and adapted. The Brazilian version was called "Questionário de Avaliação das Mamas (BEQ-Brasil)" and was demonstrated to be valid and reproducible.

Full Text Available There is a growing interest of clinical and epidemiological researches in the field of functional gastrointestinal disorders in our society. Accordingly, validated and culturally adapted instruments are required for appropriate measurement of variables specially the quality of life. The aim of our study was the linguistic validation of the Irritable Bowel Syndrome-Quality of Life questionnaire (IBS-QOL for Iranian IBS patients with Persian language. Following the standard forward-backward translation method, the IBS-QOL was translated into the Persian language and completed by 141 IBS patients. Patients also completed the IBS Symptom Severity Scale (IBS-SSS and Hospital Anxiety and Depression Scale (HADS. One-week retest was performed on 30 randomly selected patients. Internal consistency and test-retest reliability were assessed using Cronbach's alpha and intraclass correlation coefficient (ICC, respectively. To analyze the discriminant validity, the IBS-QOL scores was correlated to the IBS-SSS and HADS scores. According to the results, reliability analyses were acceptable for all of the IBS-QOL domains (Cronbach's alpha=0.68 to 0.90 and ICCs=0.77 to 0.91. Discriminant validity was supported by the presence of correlations of the IBS-QOL scores with disease severity (r = -0.628, depression (r = -0.692, and anxiety (r = -0.711 scores; P < 0.001. These results indicate that the Persian version of the IBS-QOL is a reliable instrument with sufficient psychometric requirements to assess quality of life in Iranian IBS patients with Persian language.

Full Text Available Abstract Background In epidemiological research, physical activity is usually assessed by questionnaires. Questionnaires are suitable for large study populations since they are relatively inexpensive and not very time consuming. However, questionnaire information is by definition subjective and prone to recall bias, especially among elderly subjects. The Modified Baecke Questionnaire, developed by Voorrips and coworkers, measures habitual physical activity in the elderly. The questionnaire includes questions on household activities, sports, and leisure time activities, over a time period of one year. The Modified Baecke Questionnaire results in a score to classify people as high, moderate, or low in daily physical activity, based on tertiles. Methods The validity of the Modified Baecke Questionnaire score was assessed among 21 elderly men and women using the doubly labeled water method as the reference criterion. This method is considered to be the gold standard for measuring energy expenditure in free-living individuals. Energy expenditure on physical activity is estimated by the ratio of total energy expenditure measured by the doubly labeled water method and resting metabolic rate measured by indirect calorimetry. This ratio is called the physical activity ratio. Results The Spearman correlation coefficient between the questionnaire score and the physical activity ratio (PAR was 0.54 (95% CI 0.22–0.66. Correct classification by the questionnaire occurred in 71% of participants who were in the lowest tertile of PAR, in 14% of participants in the middle tertile, and in 43% of participants in the highest tertile. Subjects were not wrongly classified in an opposite tertile. Conclusion The validity of the Modified Baecke Questionnaire is fair-to-moderate. This study shows that the questionnaire can correctly classify individuals as low or high active, but does a poor job for moderately active individuals.

Valid and reliable instruments to measure monitoring attitudes of clinicians are scarce. The influence of sociodemographics and professional characteristics on monitoring attitudes is largely unknown. First, we investigated the factor structure and reliability of the Outcome Measurement Questionnaire among a sample of Flemish mental health professionals (n = 170). Next, we examined the relationship between clinicians' sociodemographic and professional characteristics and monitoring attitudes. Construct validity was determined using a confirmatory factor analysis. Internal consistency was ascertained using Cronbach's alpha. Mean level differences in monitoring attitudes related to clinicians' gender, work setting, level of education and psychotherapeutic training, were investigated using ANOVAs. The relationships between clinicians' age, clinical experience and attitudes were calculated using the Pearson correlation coefficient. A model with one general factor and a method factor referring to reverse-worded items best fitted our data. Internal consistency was good. Clinicians with psychotherapeutic training reported more favorable monitoring attitudes than those without such training. Compared to clinicians working in subsidized outpatient services, private practitioners and clinicians from inpatient mental health clinics had more positive attitudes. Results highlight the need for sustained and targeted training, with particular focus on transforming measurement data into meaningful clinical support tools. PMID:25315180

The aim of the present study was to validate a reduced Spanish version of the Negative Acts Questionnaire (NAQ; Einarsen & Raknes, 1997). This instrument, which has been widely used in various studies, was developed to measure workplace bullying. Two samples, the first comprising 352 employees from 11 organizations, and the second comprising victims of bullying who were recruited from 15 Spanish associations against bullying, participated in the study. Exploratory factor analysis conducted with the data from the first sample revealed a two-factor solution that accounted for 63.3% of the total variance. The data from the second sample were used for confirmatory factor analyses to compare three structure models of the NAQ (one factor, two independent factors, and two correlated factors). The results indicate that the correlated two-factor model provided the best fit to the data (chi2/df = 2.1, CFI = .93, GFI = .95, RMR = .04, RMSEA = .06, AIC = 215.4). Reliability analysis showed that this 14-item Spanish version had high internal consistency. Significant correlations between the NAQ and its dimensions and diverse health and perceived stress scales were found, which provided evidence of construct validity. Taken conjointly, the results of this study support the use of the Spanish version of the reduced NAQ in future research. PMID:17992971

Full Text Available A growing body of research has examined intrusive and relatively uncontrollable thought processes, and two distinct and relatively independent lines of research have emerged. One research line has focused on the investigation of worry and the thought process implicated in the development, while the other research line has concentrated on the study of rumination and the thought processes associated with increased duration and severity of major depressive disorder. These achievements were the base for constructing The Rumination-Reflection Questionnaire RRQ. In this study the English version of 13-item were used to develop the Polish adaptation. The psychometric properties of the Polish version RRQ were assessed in a sample of 300 adults (20–50 years old. Construct validity was examined with reliability analysis of consistency (Alfa-Cronbach, confirmatory factor analyses, stability and accuracy (by relating the KRR to others measures of personality disorders, mindfulness and mysticism. The results confirmed validity of KRR (consistency and accuracy as well as usefulness of considerations based on new theoretical suggestions in psychology (two-dimensional model of rumination.

Background Treatment burden refers to the workload imposed by healthcare on patients, and the effect this has on quality of life. The Treatment Burden Questionnaire (TBQ) aims to assess treatment burden in different condition and treatment contexts. Here, we aimed to evaluate the validity and reliability of an English version of the TBQ, a scale that was originally developed in French. Methods The TBQ was translated into English by a forward-backward translation method. Wording and possible missing items were assessed during a pretest involving 200 patients with chronic conditions. Measurement properties of the instrument were assessed online with a patient network, using the PatientsLikeMe website. Dimensional structure of the questionnaire was assessed by factor analysis. Construct validity was assessed by associating TBQ global score w?th clinical variables, adherence to medication assessed by Morisky’s Medication Adherence Scale (MMAS-8), quality of life (QOL) assessed by the PatientsLikeMe Quality of Life Scale (PLMQOL), and patients’ confidence in their knowledge of their conditions and treatments. Reliability was determined by a test–retest method. Results In total, 610 patients with chronic conditions, mainly from the USA, UK, Canada, Australia, or New Zealand, completed the TBQ between September and October 2013. The English TBQ showed a unidimensional structure with Cronbach ? of 0.90. The TBQ global score was negatively correlated with the PLMQOL score (rs?=??0.50; p?0.0001). Low rather than moderate or high adherence to medication was associated with high TBQ score (mean [SD] TBQ score 61.8 [30.5] vs. 37.7 [27.5]; P?0.0001). The treatment burden was higher for patients who had insufficient knowledge compared with those who had sufficient knowledge about their treatments (mean?±?SD TBQ score 62.3?±?31.3 vs. 47.8?±?30.4; P?0.0001) and conditions (63.0?±?31.6 vs. 49.3?±?30.7; P?0.0001). The intraclass correlation coefficient for the retest (n?=?282) was 0.77 (95% CI 0.70 to 0.82). Conclusions We found that the English TBQ is a reliable instrument in this population, and provide evidence supporting the construct validity for its use to assess treatment burden for patients with one or more chronic conditions in English-speaking countries.

Face and content validity were established via an expert panel. The SQOP consists of two sections: clinical services and types of counseling. There were 23 items in total, each with a five-point Likert-type response. Satisfaction score was calculated by converting the total score to a percentage. A higher score indicates higher satisfaction. English speaking, non-osteoporotic, postmenopausal women aged ?50 years were included in the study. Participants were randomized to either the control or intervention group. Intervention participants were provided counseling, whereas control participants received none. Participants answered the SQOP at baseline and 2 weeks later.Results: A total of 140 participants were recruited (control group: n=70; intervention group: n=70. No significant differences were found in any demographic aspects. Exploratory factor analysis extracted seven domains. Cronbach’s a for the domains ranged from 0.531–0.812. All 23 items were highly correlated using Spearman’s correlation coefficient 0.469–0.996 (P<0.05, with no significant change in the control group’s overall test–retest scores, indicating that the SQOP achieved stable reliability. The intervention group had a higher score than the control group (87.91±5.99 versus 61.87±8.76; P<0.05, indicating that they were more satisfied than control participants. Flesch reading ease was 62.9.Conclusion: The SQOP was found to be a valid and reliable instrument for assessing patients’ satisfaction towards an osteoporosis screening and prevention service in Malaysia.

OBJECTIVE: To examine the validity of the Recent Physical Activity Questionnaire (RPAQ) which assesses physical activity (PA) in 4 domains (leisure, work, commuting, home) during past month. METHODS: 580 men and 1343 women from 10 European countries attended 2 visits at which PA energy expenditure (PAEE), time at moderate-to-vigorous PA (MVPA) and sedentary time were measured using individually-calibrated combined heart-rate and movement sensing. At the second visit, RPAQ was administered electronically. Validity was assessed using agreement analysis. RESULTS: RPAQ significantly underestimated PAEE in women [median(IQR) 34.1 (22.1, 52.2) vs. 40.6 (32.4, 50.9) kJ/kg/day, 95%LoA: -44.4, 63.4 kJ/kg/day) and in men (43.7 (29.0, 69.0) vs. 45.5 (34.1, 57.6) kJ/kg/day, 95%LoA: -47.2, 101.3 kJ/kg/day]. Using individualised definition of 1MET, RPAQ significantly underestimated MVPA in women [median(IQR): 62.1 (29.4, 124.3) vs. 73.6 (47.8, 107.2) min/day, 95%LoA: -130.5, 305.3 min/day] and men [82.7 (38.8, 185.6) vs.83.3 (55.1, 125.0) min/day, 95%LoA: -136.4, 400.1 min/day]. Correlations (95%CI) between subjective and objective estimates were statistically significant [PAEE: women, rho = 0.20 (0.15-0.26); men, rho = 0.37 (0.30-0.44); MVPA: women, rho = 0.18 (0.13-0.23); men, rho = 0.31 (0.24-0.39)]. When using non-individualised definition of 1MET (3.5 mlO2/kg/min), MVPA was substantially overestimated (? 30 min/day). Revisiting occupational intensity assumptions in questionnaire estimation algorithms with occupational group-level empirical distributions reduced median PAEE-bias in manual (25.1 kJ/kg/day vs. -9.0 kJ/kg/day, p<0.001) and heavy manual workers (64.1 vs. -4.6 kJ/kg/day, p<0.001) in an independent hold-out sample. CONCLUSION: Relative validity of RPAQ-derived PAEE and MVPA is comparable to previous studies but underestimation of PAEE is smaller. Electronic RPAQ may be used in large-scale epidemiological studies including surveys, providing information on all domains of PA.

Full Text Available Introduction: ADHD is one of the most common diagnoses in child psychiatry, its early diagnosis is of great importance for intervention at family, school and social environment. Based on the International Classification of Functioning, Disability and Health (ICF, a questionnaire was designed to assess activity limitations and participation restrictions in children with ADHD. The questionnaire was called “CLARP-ADHD Parent and Teacher Version”. Objective: To determine the degree of internal consistency of the CLARP-ADHD questionnaire, and its concurrent validity with the “Strengths and Difficulties Questionnaire SDQ parent and teacher version”. Material and Methods: A sample of 203 children aged 6 to 12 with ADHD, currently attending school in five Colombian cities. The questionnaires were applied to parents and teachers. The internal consistency analysis was performed through Cronbach coefficient and concurrent validity using the Spearman correlation coefficient utilizing multiple and unique predictors through multiple linear regression as well as simple regression models. Results: A high internal consistency was found for global questionnaires for each of its domains. The CLARP-ADHD for parents gave as result an internal consistency of 0.83, and the CLARP-ADHD for teachers one of 0.93. Concurrent validity was found between the CLARP-ADHD and the SDQ Parent and Teacher version; also, concurrence between the CLARPADHD for Teachers and the SDQ Teachers was found, as well as between CLARP ADHD for Parents and CLARP ADHD Teachers, given by p values of p < 0.001.

Full Text Available Abstract Background Validation of a food frequency questionnaire (FFQ is important as incorrect information may lead to biased associations. Therefore the relative validity of an FFQ developed for use in the German Health Examination Survey for Adults 2008-2011 (DEGS was examined. Methods Cross-sectional comparisons of food consumption data from the FFQ and from two 24-hour recalls were made in a sample of 161 participants (aged 18 to 80 years of an ongoing nationwide survey, the German National Nutrition Monitoring (NEMONIT. The data collection took place from November 2008 to April 2009. Results Spearman rank correlations between the FFQ and the 24-hour dietary recalls ranged from 0.15 for pizza to 0.80 for tea, with two third of the correlation coefficients exceeding 0.30. All correlation coefficients were statistically significant except those for pizza and cooked vegetables. The proportion of participants classified into the same or adjacent quartile of intake assessed by both methods varied between 68% for cooked vegetables and 94% for coffee. There were no statistically significant differences in food consumption estimates between both methods for 38% of the food groups. For the other food groups, the estimates of food consumption by the FFQ were not generally higher or lower than estimates from the 24-hour dietary recalls. Conclusions The FFQ appears to be reasonably valid in the assessment of food consumption of German adults. For some food groups, such as raw and cooked vegetables, relative risks estimates should be interpreted with caution because of the poor ranking agreement.
After Alzheimer's disease, Parkinson's disease (PD) is the second most frequent degenerative disease of the central nervous system. The consequences of PD at the functional, social and emotional levels warrant a better understanding the patient's perceptions as measured using a specific instrument rather than restricting the medical approach to the clinical evaluation of the motor component. In 1996, we began implementation of a project to transculturally validate the single specific instrument that had been published and was available at that time: PDQ-39. The scale consists in a 39-item questionnaire enabling determination of an overall quality-of-life score and scores for 8 specific dimensions: mobility, activities of daily living, emotional well-being, stigma, social support, cognitions, communication and bodily discomfort. Eighty-nine patients taking part in an open-label study of the safety of a combination of pergolide and dopa therapy were included and followed up on D15 and after 8 weeks. The process of "Forward-Backward" translation, conducted in close liaison with the authors, enabled semantic and linguistic validation of the French language version. The content was validated by PD experts. At baseline, the patients presented quality-of-life scores that were particularly impaired for the dimensions exploring Mobility, Emotional well-being and Bodily discomfort. The main metric properties of the scale were confirmed. The PDQ-39 scores were closely correlated with the related concepts investigated by generic scale, SF-36. The PDQ-39 scores were correlated with the "Mental and Mood Status", "Everyday Activities" and "Motor Status" dimensions determined by the UPDRS. The reliability, expressed by Cronbach coefficients alpha, showed strong consistency of the instrument, very similar to the data for the original version. In contrast to what was observed with SF-36, the scale was particularly sensitive to clinical changes. The initial results make PDQ-39 a precious tool for the optimization of management of patients presenting with PD. PMID:11938321

The Sociocultural Attitudes Towards Appearance Questionnaire-3 (SATAQ-3) and its earlier versions are measures designed to assess societal and interpersonal aspects of appearance ideals. Correlational, structural equation modeling, and prospective studies of the SATAQ-3 have shown consistent and significant associations with measures of body image disturbance and eating pathology. In the current investigation, the SATAQ-3 was revised to improve upon some conceptual limitations and was evaluated in 4 U.S. and 3 international female samples, as well as a U.S. male sample. In Study 1, exploratory and confirmatory factor analyses for a sample of women from the Southeastern United States (N = 859) indicated a 22-item scale with 5 factors: Internalization: Thin/Low Body Fat, Internalization: Muscular/Athletic, Pressures: Family, Pressures: Media, Pressures: Peers. This scale structure was confirmed in 3 independent and geographically diverse samples of women from the United States (East Coast N = 440, West Coast N = 304, and North/Midwest N = 349). SATAQ-4 scale scores demonstrated excellent reliability and good convergent validity with measures of body image, eating disturbance, and self-esteem. Study 2 replicated the factorial validity, reliability, and convergent validity of the SATAQ-4 in an international sample of women drawn from Italy, England, and Australia (N = 362). Study 3 examined a sample of college males from the United States (N = 271); the 5-factor solution was largely replicated, yet there was some evidence of an underlying structure unique to men. Future research avenues include additional item testing and modification of the scale for men, as well as adaptation of the measure for children and adolescents.

Research has suggested that mindfulness and acceptance may be important factors in the development, maintenance and treatment of both obesity and eating disorders. However, very few scales exist that apply constructs of acceptance and mindfulness to eating behavior. A measure of acceptance about food related thoughts would be especially beneficial in investigating links between acceptance and problematic eating, and in better understanding mechanisms of action of effective treatments for obesity and eating disorders. The Food Acceptance and Awareness Questionnaire (FAAQ) was developed to measure acceptance of urges and cravings to eat or the extent to which individuals might try to control or change these thoughts. The FAAQ is a self-report questionnaire made up of ten items each rated on a seven-point Likert scale (1=very seldom true to 6=always true). Higher scores indicate greater acceptance of motivations to eat. The FAAQ was given to a sample of 463 undergraduate students along with several other measures of eating behavior and other psychological variables. Concurrent associations with variables theorized to be closely linked (Eating Attitudes Test, EAT; the Dutch Eating Behavior Questionnaire, DEBQ; body mass index, BMI) and not very closely linked (the Depression Anxiety Stress Scale, DASS) were evaluated in order to indicate the new scale's convergent and divergent validity. These results demonstrated highly significant correlations with these measures in the expected direction, with stronger correlations for the theoretically-consistent variables than the theoretically-inconsistent variables. Exploratory factor analyses confirmed a structural two-factor model. Factor 1 seems to measure one's ability to regulate eating despite urges and cravings, and Factor 2 seems to measure desire to maintain internal control over eating thoughts. The FAAQ was also administered to a separate sample of 29 overweight or obese women enrolled in a weight loss program, and found to be predictive of weight loss. Taken together, results suggest that the FAAQ is a psychometrically sound instrument which might be a valuable tool for assessing acceptance of food related thoughts and urges. PMID:21741015

Full Text Available Objective: The objective of the study was to assess the reliability and validity of the Hindi translation of the Migraine Disability Assessment (MIDAS and Headache Impact Test-6 (HIT-6 questionnaires. Materials and Methods: The study was conducted on the migraine patients. For test-retest reliability, the respondents filled the MIDAS and HIT-6 questionnaires twice, at an interval of three weeks. For validity, the same population of patients filled the headache diary for three months. After three months they filled the MIDAS and HIT-6 questionnaires again. The patients were subgrouped according to their occupation and level of education. The test-retest reliability and validity were calculated by the Pearson correlation coefficient. Internal consistency was calculated using the Cronbach alpha. Results: A total of 236 migraine patients were screened. Seventy-nine patients fulfilled the inclusion criteria. A total of 69 patients completed the study. The HIT-6 questionnaire was applicable to all the subgroups of patients and had better comprehensibility than the MIDAS. Housewives missed out on the first two questions of the MIDAS and had lower mean MIDAS scores than HIT-6. The test-retest correlation coefficients for the total MIDAS and HIT-6 scores were 0.94 and 0.81, respectively. The correlation coefficients between the total score in the headache diary equivalent and the MIDAS and HIT-6 total score were 0.91 and 0.77, respectively. Cronbach alpha, a measure of internal consistency for the MIDAS questionnaire was > 0.90 at all the compilations. For the HIT-6 questionnaire, it ranged from 0.67 to 0.79. Conclusion: The Hindi versions of MIDAS and HIT-6 questionnaires were reliable and valid, but could not be interchanged. HIT-6 had better comprehensibility.
(1) To assess the degree of convergence between the 1990 and 2010 American College of Rheumatology (ACR) diagnostic criteria; (2) To evaluate the validity and reliability of the 2010 ACR criteria; (3) To validate the Spanish version of the Fibromyalgia Survey Questionnaire (FSQ); and (4) To assess the utility of the FSQ to differentiate fibromyalgia (FM) subgroups by disease severity. In the first study, agreement between the 1990 and 2010 ACR criteria for FM diagnosis was analyzed in a sample of 80 FM patients and 59 healthy controls. Algometry (mean threshold and tender points count) and the 2010 ACR indices [Symptom Severity Scale (SSS), Widespread Index (WPI) and Polysymptomatic Distress Scale (PSD)] were correlated with the key symptoms of FM and with indices of disease interference and quality of life. In a second study, we evaluated the validity and internal consistency of the Spanish version of the FSQ, as well as its ability to discriminate between groups of FM patients with low and high symptom severity. There is good agreement between the 1990 and 2010 ACR criteria for FM diagnosis. The 2010 ACR indices (SSS, WPI and PSD) demonstrated very adequate construct validity and appeared to be useful in the assessment of disease severity and global impact of FM. The FSQ had good internal consistency and validity and showed 100 % concordance with 2010 ACR criteria applied by a clinician. In addition, the FSQ proved to be useful in differentiating FM severity subgroups. PMID:24952419

Full Text Available Abstract Background Although physical activity maintenance is important for OA management, it is not clear whether people with OA are more inactive or not. One possible reason is no simple monitoring tool to assess physical activity at the clinic. The aim of this study was to determine the reliability and validity of the Baecke Physical Activity Questionnaire (BQ in adult women with hip disorders. Methods Sixty-four patients with unilateral or bilateral hip disorders were recruited from an outpatients clinic at a university hospital in Japan. BQ includes a total of 16 questions classified into three domains: work, sports, and non-sports leisure activity. For test-retest reliability, one BQ was administrated face-to-face, and a second was mailed to participants two weeks later. Test-retest reliability of BQ was assessed using intra-class correlation (ICC and Bland and Altman method. To determine criterion validity, the correlation between BQ measurements and pedometer-measured step counts was assessed. Correlations between BQ measurements and step counts were assessed using Spearman rank correlation coefficient (rho. Results Analyses were restricted to the 61 patients (53.3 ± 11.3 years old who wore the pedometer continuously for 5 days or more. Twenty eight patients had unilateral hip osteoarthritis, 17 patients had unilateral total hip arthroplasty, and 16 patients had hip osteoarthritis and total hip arthroplasty. The mean step count was 6,309 ± 2,392 steps/day. In analysis for reliability, the value of ICC was 0.84 for work, 0.83 for sports, 0.78 for non-sports leisure activity, and 0.87 total. Bland and Altman analysis showed the step count and BQ total did not differ significantly from 0 with most falling between 0 ± 1.96 SD. In analysis for validity, there was a significant but low to moderate correlation between step counts and 3 BQ subscales (rho, 0.30–0.49 and a higher correlation between step counts and total score (rho, 0.49. Conclusion BQ is a useful monitoring tool for assessing multiple domains of physical activity with acceptable reliability and validity in adult women with hip disorders.
Background Neuropsychiatric symptoms (NPS) are common in Mild Cognitive Impairment (MCI) and Alzheimer's Disease (AD) and often measured using the Neuropsychiatric Inventory (NPI). Development of validated subscales that measure clinically meaningful symptom clusters would improve capacity for individualized treatment and assessment of treatment interventions. We report preliminary validation of three NPI Questionnaire (NPI-Q) subscales derived from examination of the existing exploratory literature and clinical knowledge. Methods The validity of subscales that assess Frontal, Agitation/Aggression, and Mood symptoms (based on NPI-Q-10 item scores) was ascertained by comparison of cross-sectional data from amnestic MCI and AD dementia cases from the National Alzheimer's Coordinating Center (NACC) and Alzheimer's Disease Neuroimaging Initiative (ADNI) databases. The statistical approach was confirmatory unrotated principal component analysis. Results ADNI contributed 103 MCI, 90 MCI-converters and 112 AD dementia cases while NACC had 1042, 763, and 3048. Baseline mean age was higher in NACC (74.6 vs 75.7). Patients in NACC were significantly more impaired at last visit on MMSE (mean scores 19.5 vs 22.4) and NPI-Q-10 (5.0 vs 4.3), as well as for each of the three subscales (NPI-Q-4-Frontal, NPI-Q-4-Agitation/Aggression, and NPI-Q-3-Mood than ADNI (at month 24). Medians were not different for Agitation/Aggression or Mood subscales, however. Each item on all scales contributed variance in PCA Pareto plots. All items in Factor (F) 1 for each scale projected in a positive direction on biplots (coherence), while F2 and F3 items showed more spatial separation (independence). Scale analyses showed remarkable similarities between ADNI and NACC cohorts for factor loadings and spatial patterns of item projections, though factor item identities varied somewhat, especially beyond F1. Conclusions The similar pattern of results across two cohorts of patients support the validity of these constructs. These subscales are worthy of further psychometric evaluation in patients with MCI and AD dementia and preliminary application in clinical settings. PMID:23602309

Full Text Available Abstract Background The 14-item Treatment Satisfaction Questionnaire for Medication (TSQM Version 1.4 is a reliable and valid instrument to assess patients' satisfaction with medication, providing scores on four scales – side effects, effectiveness, convenience and global satisfaction. In naturalistic studies, administering the TSQM with the side effects domain could provoke the physician to assess the presence or absence of adverse events in a way that is clinically atypical, carrying the potential to interfere with routine medical care. As a result, an abbreviated 9-item TSQM (TSQM-9, derived from the TSQM Version 1.4 but without the five items of the side effects domain was created. In this study, an interactive voice response system (IVRS-administered TSQM-9 was psychometrically evaluated among patients taking antihypertensive medication. Methods A total of 3,387 subjects were invited to participate in the study from an online panel who self-reported taking a prescribed antihypertensive medication. The subjects were asked to complete the IVRS-administered TSQM-9 at the start of the study, along with the modified Morisky scale, and again within 7 to 14 days. Standard psychometric analyses were conducted; including Cronbach's alpha, intraclass correlation coefficients, structural equation modeling, Spearman correlation coefficients and analysis of covariance (ANCOVA. Results A total of 396 subjects completed all the study procedures. Approximately 50% subjects were male with a good racial/ethnic mix: 58.3% white, 18.9% black, 17.7% Hispanic and 5.1% either Asian or other. There was evidence of construct validity of the TSQM-9 based on the structural equation modeling findings of the observed data fitting the Decisional Balance Model of Treatment Satisfaction even without the side effects domain. TSQM-9 domains had high internal consistency as evident from Cronbach's alpha values of 0.84 and greater. TSQM-9 domains also demonstrated good test-retest reliability with high intraclass correlation coefficients exceeding 0.70. As expected, the TSQM-9 domains were able to differentiate between individuals who were low, medium and high compliers of medication, with moderate to high effect sizes. There was evidence of convergent validity with significant correlations with the medication adherence scale. Conclusion The IVRS-administered TSQM-9 was found to be a reliable and valid measure to assess treatment satisfaction in naturalistic study designs, in which there is potential that the administration of the side effects domain of the TSQM would interfere with routine clinical care.

OBJECTIVE: The objective of this study was to examine the psychometric properties of the Danish version of the Barriers Questionnaire-II (DBQ-II). METHODS: The validated Norwegian version of the DBQ-II was translated into Danish. Cancer patients for the study were recruited from specialized pain management facilities. Thirty-three patients responded to the DBQ-II, Hospital Anxiety and Depression Scale, and Brief Pain Inventory pain severity scale. RESULTS: A factor analysis of the DBQ-II resulted in six scales. Scale one, Fatalism, consisted of three items addressing fatalistic beliefs regarding cancer pain management. Scale two, Immune System, consisted of three items addressing the belief that pain medications harm the immune system. Scale three, Monitor, consisted of three items addressing the fear that pain medicine masks changes in one's body. Scale four, Communication, consisted of five items addressing the concern that reports of pain distract the physician from treating the cancer, and the belief that"good" patients do not complain. Scale five, Addiction, consisted of two items addressing the fear of becoming addicted to pain medication. Finally, scale six, Tolerance, consisted of three items addressing the fear of getting tolerant to analgesic effect of pain medicine. Items related to medication side effects were analyzed as separate units. The DBQ-II total had an internal consistency of 0.87. The DBQ-II total score was related to measures of pain relief and anxiety. CONCLUSIONS: The DBQ-II seems to be a reliable and valid measure of the barriers to pain management among Danish cancer patients.

This study reports on the initial development and validation of the Student Subjective Wellbeing Questionnaire (SSWQ) with a sample of 1,002 students in Grades 6-8. The SSWQ is a 16-item self-report instrument for assessing youths' subjective wellbeing at school, which is operationalized via 4 subscales measuring school connectedness, academic efficacy, joy of learning, and educational purpose. The conceptualization and development of the SSWQ's subscales and items are described, and results from a series of preliminary psychometric analyses are reported. Findings indicated that the SSWQ was characterized by 4 conceptually sound latent factors, that these 4 first-order factors were robust indicators of a single second-order factor (i.e., student subjective wellbeing), that all subscales and the composite scale demonstrated at least adequate construct reliability and internal consistency, and that the estimated latent-means for all first-order and second-order factors were invariant across gender. Moreover, results from bivariate correlations and a latent-variable path analysis provided evidence in support of the construct validity of the SSWQ's scales and latent factors, showing strong associations with other student wellbeing indicators (i.e., school prosociality and academic perseverance), while findings from binary logistic regressions demonstrated that overall student subjective wellbeing levels, based on composite scores from the SSWQ, were mildly to-strongly associated with a variety of self-endorsed risk factors (e.g., aggression and self-harm) and protective factors (e.g., social support and physical exercise). Implications for theory, research, and the practice of school psychology are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved). PMID:25180834

OBJECTIVE: To evaluate the validity of the Inter99 food frequency questionnaire (FFQ) compared with a 28-days' diet history and biomarkers. SUBJECTS: A random sample of 13 016 individuals were drawn from a general population and invited for a health screening programme. Participation rate was 52.5%. All high-risk individuals were re-invited for assessment after 1 and 3 years and completed a 198-item FFQ at all three occasions. Participants attending for 3 years follow-up were invited to participate in the validation study, including a 28-days' diet history, a 24-h urine collection and a fasting blood sample. Overall, 264 subjects participated. RESULTS: Spearman's rank correlation coefficients between the two dietary methods ranged from 0.31(beta-carotene) to 0.64 (fruits) in men and from 0.31 (polyunsaturated fat and sodium) to 0.64 (fruits) for women. The proportion of individuals classified in the same or adjacent quintiles were, on average, 72% for men and 69% for women. Gross misclassification was found on average in 2%. The correlation coefficients of the residuals ranged from 0.27 (sodium) to 0.61 (fruits) for men and from 0.21 (sodium) to 0.62 (B12-vitamin) for women. Correlation coefficients between fruit and vegetable intake and carotenoids ranged from -0.08 (lycopene) to 0.44 (alpha-carotene). For the residuals the correlation coefficients ranged from -0.004 (lycopene) to 0.47 (alpha-carotene). CONCLUSION: The Inter99 FFQ and the residuals of the intake provide acceptable classification of individuals according to their dietary intakes and the FFQ gives a good quantitative measurement of key dietary components.

The study was designed to validate the Patient Health Questionnaire (PHQ-9) for depression risk identification among pregnant women. Pregnant women were routinely administered the Prenatal Risk Overview, a comprehensive psychosocial screening interview, which included the PHQ-9, at their prenatal intake appointment at three community clinics. Study participants completed the Structured Clinical Interview for DSM-IV (SCID) at a later appointment. PHQ-9 risk classifications were cross-tabulated with SCID diagnostic categories to examine concordance, sensitivity, specificity, and positive and negative predictive values. The study sample included 745 women. Prevalence of a current major depressive episode was 3.6 %; an additional 7.0 % were classified as meeting subdiagnostic criteria of three or more depressive symptoms. A PHQ-9 score cutoff of 10 yielded sensitivity and specificity rates of 85 and 84 %, respectively, for a depression diagnosis and 75 and 88 % for a subdiagnosis, respectively. Positive predictive value was higher for the expanded group (43 %) than that of the diagnosis-only group (17 %). The PHQ-9, embedded within a multidimensional risk screening interview, effectively identified pregnant women who met criteria for current depression. The moderate risk score cutoff also identified women with subdiagnostic symptom levels who may benefit from interventions to alleviate their distress and improve pregnancy outcomes. PMID:22983357

Full Text Available Abstract Background Community based prevalence for diabetes related foot disease (DRFD has been poorly quantified in Australian populations. The aim of this study was to develop and validate a survey tool to facilitate collection of community based prevalence data for individuals with DRFD via telephone interview. Methods Agreed components of DRFD were identified through an electronic literature search. Expert feedback and feedback from a population based construction sample were sought on the initial draft. Survey reliability was tested using a cohort recruited through a general practice, a hospital outpatient clinic and an outpatient podiatry clinic. Level of agreement between survey findings and either medical record or clinical assessment was evaluated. Results The Questionnaire for Diabetes Related Foot Disease (Q-DFD comprised 12 questions aimed at determining presence of peripheral sensory neuropathy (PN and peripheral vascular disease (PVD, based on self report of symptoms and/or clinical history, and self report of foot ulceration, amputation and foot deformity. Survey results for 38 from 46 participants demonstrated agreement with either clinical assessment or medical record (kappa 0.65, sensitivity 89.0%, and specificity 77.8%. Correlation for individual survey components was moderate to excellent. Inter and intrarater reliability and test re-test reliability was moderate to high for all survey domains. Conclusion The development of the Q-DFD provides an opportunity for ongoing collection of prevalence estimates for DRFD across Australia.

Schizotypal traits represent the behavioral expression of vulnerability to psychosis in general population. Among the most widely used measurement instruments, we could find the Schizotypal Personality Questionnaire (SPQ) (Raine, 1991). However, some aspects of its psychometric quality have yet to be analyzed. The main goal of the present study was to gather new sources of validity evidence of the SPQ scores in non-clinical young adults. The final sample was made up of 1123 college students (M=20.3 years; S.D.=2.6). The study of the internal structure using exploratory factor analysis revealed that SPQ items were grouped in a theoretical structure of seven second-order factors. Confirmatory factor analyses showed that the four-factor model (Paranoid) displayed better goodness-of-fit indices than the other hypothetical dimensional models tested. More complex measurement models, such as those tested using second-order confirmatory factor analyses and Exploratory Structural Equation Modeling, also showed adequate goodness-of-fit indices. The reliability of the SPQ scores ranged from 0.80 to 0.91. A total of 11 items showed differential functioning by gender. Advances in psychosis phenotype measurement open up new horizons to understand the structure and content of schizotypy. PMID:24889846

Full Text Available Abstract Background Burnout is a mental condition defined as a result of continuous and long-term stress exposure, particularly related to psychosocial factors at work. This paper seeks to examine the psychometric properties of the Shirom-Melamed Burnout Questionnaire (SMBQ for validation of use in a clinical setting. Methods Data from both a clinical (319 and general population (319 samples of health care and social insurance workers were included in the study. Data were analysed using both classical and modern test theory approaches, including Confirmatory Factor Analysis (CFA and Rasch analysis. Results Of the 638 people recruited into the study 416 (65% persons were working full or part time. Data from the SMBQ failed a CFA, and initially failed to satisfy Rasch model expectations. After the removal of 4 of the original items measuring tension, and accommodating local dependency in the data, model expectations were met. As such, the total score from the revised scale is a sufficient statistic for ascertaining burnout and an interval scale transformation is available. The scale as a whole was perfectly targeted to the joint sample. A cut point of 4.4 for severe burnout was chosen at the intersection of the distributions of the clinical and general population. Conclusion A revised 18 item version of the SMBQ satisfies modern measurement standards. Using its cut point it offers the opportunity to identify potential clinical cases of burnout.
Full Text Available The self-determination theory is a psychological approach to motivation that focuses on causes and consequences of human behavior regulation. According several authors, this theoretical framework could provide important information about the student’s motivational process to physical education class, however, in Portugal does not exists any instrument to measure the basic psychological needs in this domain. So, the main propose of this study is the preliminary adaptation to physical education contexts of Basic Psychological Needs Exercise Scale (Portuguese version: BPNESp, and determine their initial psychometrics properties through an exploratory factor analysis. This propose was accomplished with a sample of 150 students (n=150 from de 2nd and 3rd CEB, aged from 11 to 16 years (M = 13.39, SD = 1.44 with different levels of sports practice. Results revealed a factorial structure just like the original model (12 items grouped in 3 factors, with 4 items hitch factor and presents acceptable values of validity and reliability. Those findings allow us to conclude, that questionnaire can be used in future investigations to measure the basic psychological needs in physical education.
Full Text Available Abstract Background The objective of the study is to improve general practitioners' diagnoses of adolescent depression. Major depression is ranked fourth in the worldwide disability impact. Method/Design Validation of 1 three key questions, 2 SCL-dep6, 3 SCL-10, 4 9 other SCL questions and 5 WHO-5 in a clinical study among adolescents. The Composite International Diagnostic Interview (CIDI is to be used as the gold standard interview. The project is a GP multicenter study to be conducted in both Norway and Denmark. Inclusion criteria are age (14–16 and fluency in the Norwegian and Danish language. A number of GPs will be recruited from both countries and at least 162 adolescents will be enrolled in the study from the patient lists of the GPs in each country, giving a total of at least 323 adolescent participants. Discussion The proportion of adolescents suffering from depressive disorders also seems to be increasing worldwide. Early interventions are known to reduce this illness. The earlier depression can be identified in adolescents, the greater the advantage. Therefore, we hope to find a suitable questionnaire that could be recommended for GPs.

This study examined the applicability of the English and Filipino versions of the Facilitating Conditions Questionnaire (FCQ) among Filipino high school students. The FCQ measures the external forces in students' social environments that can influence their motivation for school. It is composed of 11 factors: university intention, school valuing, parent support, teacher support, peer help, leave school, pride from others, negative parent influence, affect to school, negative peer influence, and positive peer influence. It was translated into conversational Filipino. Seven hundred sixty-five high school students answered one of the two language versions. Both within-network and between-network approaches to construct validation were used. Confirmatory factor analyses (CFA) of the two versions showed good fit. Results of the multigroup CFA indicated that there was invariance in terms of factor loadings for the two versions. Results of the between-network test also showed that the factors in the FCQ correlated systematically with theoretically relevant constructs. Taken together, this study supports the applicability of the FCQ for use with Filipino bilingual adolescents. PMID:23646097

Absence and sick-leave data was extracted from administrative records.Results: Factor analysis revealed acceptable validity for the questionnaire in part A (health. Cronbach's alpha was >0.73 for all scales of Parts B (work and C (demographic. Questions targeting days of absence and sick-leave had acceptable correlation with administrative records (Pearson's r >0.75, while questions on total hours worked showed lower correlation.Conclusion: Persian version of HPQ can be considered a reliable and valid tool in Iranian health workers.
Full Text Available Aims: The objective of this study was to determine the reliability and validity of the eight-item Short Form Health Survey (SF-36 questionnaire translated into Persian for use in Iranian patients with thalassemia major. Materials and Methods: Using a standard "forward-backward" translation procedure, the English language version of the questionnaire was translated into Persian. Two hundred patients with thalassemia major following up at the Thalassemia Center, Dastgheib Hospital, Shiraz, Iran, were enrolled in this study. Statistical Analysis: The reliability and internal consistency of the questionnaire were assessed by Cronbach?s alpha coefficient and Spearman?s correlation, respectively. Validity was assessed using convergent and discriminant validity. Results: The mean age of 200 subjects enrolled in the study was 19.81+/-4.07 years. Reliability analysis showed satisfactory results (Cronbach?s a coefficient = 0.915. The factor analysis showed that all items were in the same groups as previous studies with the exception of role emotional and general health that had been substituted. Most of the patients were in lower range of normal for both mental and physical summary status. Conclusions: The study finding showed that the Persian version of SF-36 questionnaire has a good structural characteristic and is a reliable and valid instrument for measuring the quality of life of patients with thalassemia major.

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.

This paper presents the results of a study aimed at validating psychological questionnaires evaluating temperamental and personality features. It discusses their usefulness in diagnosing drivers' aptitude for safe driving and working as professional drivers. Three psychological questionnaires were validated: the Formal Characteristics of Behaviour - Temperament Inventory (FCB-TI), the Eysenck Personality Questionnaire - Revised and Short Scale (EPQ-R (S)) and the Impulsiveness Questionnaire (IVE). Three groups of drivers (n=246) aged 19-75 participated in the study. Group I (professional drivers; n=96) and Group II (nonprofessional drivers; n=75) had never been involved in road crashes, whereas Group III (nonprofessional drivers; n=75) were offenders involved in fatal injury road crashes. Criterion-related validity, Cronbach's alpha and Guttman split-half reliability coefficient were in assessing the psychometric properties of the questionnaires. There were some significant differences between Groups II and III for most traits. However, contrary to expectations, higher Emotional Reactivity, Perseveration and lower Endurance as well as higher Neuroticism, Impulsiveness and Venturesomeness were determined for Group II than for Group III. Additionally, the temperament and personality profile of Group II turned out to be less fitted to the profile of safe drivers than that of Group III, whose profile was actually similar to that of Group I. This seems to result from a high tendency for a positive self-presentation among Group I and Group III (a significantly higher result on the Lie scale in comparison with Group II). The results suggest that if psychological tests are to decide on whether a person may be a professional driver or may drive vehicles, the three questionnaires (FCB-TI, EPQ-R(S) and IVE) do not provide a valid diagnosis of professional drivers' aptitude because of drivers' high tendency for positive self-presentation. However, they can be used in job counselling and in screening high-risk drivers. PMID:24831270

Full Text Available Abstract Background Achilles tendinopathy is the predominant overuse injury in runners. To further investigate this overload injury in transverse and longitudinal studies a valid, responsive and reliable outcome measure is demanded. Most questionnaires have been developed for English-speaking populations. This is also true for the VISA-A score, so far representing the only valid, reliable, and disease specific questionnaire for Achilles tendinopathy. To internationally compare research results, to perform multinational studies or to exclude bias originating from subpopulations speaking different languages within one country an equivalent instrument is demanded in different languages. The aim of this study was therefore to cross-cultural adapt and validate the VISA-A questionnaire for German-speaking Achilles tendinopathy patients. Methods According to the "guidelines for the process of cross-cultural adaptation of self-report measures" the VISA-A score was cross-culturally adapted into German (VISA-A-G using six steps: Translation, synthesis, back translation, expert committee review, pretesting (n = 77, and appraisal of the adaptation process by an advisory committee determining the adequacy of the cross-cultural adaptation. The resulting VISA-A-G was then subjected to an analysis of reliability, validity, and internal consistency in 30 Achilles tendinopathy patients and 79 asymptomatic people. Concurrent validity was tested against a generic tendon grading system (Percy and Conochie and against a classification system for the effect of pain on athletic performance (Curwin and Stanish. Results The "advisory committee" determined the VISA-A-G questionnaire as been translated "acceptable". The VISA-A-G questionnaire showed moderate to excellent test-retest reliability (ICC = 0.60 to 0.97. Concurrent validity showed good coherence when correlated with the grading system of Curwin and Stanish (rho = -0.95 and for the Percy and Conochie grade of severity (rho 0.95. Internal consistency (Cronbach's alpha for the total VISA-A-G scores of the patients was calculated to be 0.737. Conclusion The VISA-A questionnaire was successfully cross-cultural adapted and validated for use in German speaking populations. The psychometric properties of the VISA-A-G questionnaire are similar to those of the original English version. It therefore can be recommended as a sufficiently robust tool for future measuring clinical severity of Achilles tendinopathy in German speaking patients.
Background and purpose: Patient self-assessment of symptom severity provides clinicians and researchers with important information. It is crucial to evaluate the validity of a self-assessment questionnaire in the context of its intended use. The objective of this study was to evaluate the validity of the uro-gynaecological questionnaire (UGQ), a new instrument for patient self-assessment of urological-, genital-, menopausal-, and pain symptomatology in gynaecological cancer patients. Material and methods: The UGQ was developed after literature review, patient- and expert interviews and pilot testing. From February 1992 to October 1992, 88 gynaecological cancer patients were invited to participate in a validation study after the initiation of their primary radiotherapy or chemotherapy. The method of validation investigated whether patients and researchers interpreted the items of the questionnaire in the same way. The patient's written response before interview was compared with an observer rating of the patient's open-ended audio-taped responses to the same questionnaire, administered as an interview. Qualitative recordings by the observer were made to describe potential misinterpretations. Results: The agreement between the patient's and the observer's ratings was high: the median overall agreement was 0.91 (range 0.71-1.00) and the median kappa was 0.88 (range 0.45-1.00). The quantitative and the qualitative results identified a few minor validity problems; especialed a few minor validity problems; especially, the issue of selective reporting, i.e. some patients only reporting those symptoms they considered relevant for the study, which may lead to systematic errors. Conclusions: The results strongly suggest that patients interpret the UGQ items as intended, i.e. they are valid. The UGQ is recommended for patient self-assessment of uro-gynaecological morbidity in gynaecological cancer patients
Full Text Available Background: The dementia diagnosis gap in sub-Saharan Africa (SSA is large, partly due to difficulties in assessing function, an essential step in diagnosis. Objectives: As part of the Identification and Intervention for Dementia in Elderly Africans (IDEA study, to develop, pilot, and validate an Instrumental Activities of Daily Living (IADL questionnaire for use in a rural Tanzanian population to assist in the identification of people with dementia alongside cognitive screening. Design: The questionnaire was developed at a workshop for rural primary healthcare workers, based on culturally appropriate roles and usual activities of elderly people in this community. It was piloted in 52 individuals under follow-up from a dementia prevalence study. Validation subsequently took place during a community dementia-screening programme. Construct validation against gold standard clinical dementia diagnosis using DSM-IV criteria was carried out on a stratified sample of the cohort and validity assessed using area under the receiver operating characteristic (AUROC curve analysis. Results: An 11-item questionnaire (IDEA-IADL was developed after pilot testing. During formal validation on 130 community-dwelling elderly people who presented for screening, the AUROC curve was 0.896 for DSM-IV dementia when used in isolation and 0.937 when used in conjunction with the IDEA cognitive screen, previously validated in Tanzania. The internal consistency was 0.959. Performance on the IDEA-IADL was not biased with regard to age, gender or education level. Conclusions: The IDEA-IADL questionnaire appears to be a useful aid to dementia screening in this setting. Further validation in other healthcare settings in SSA is required.
Full Text Available A validated questionnaire to assess the impact of small bowel obstructions (SBO on patients’ quality of life was developed and validated. The questionnaire included measurements for the impact on the patients’ quality of life in respect to diet, pain, gastrointestinal symptoms and daily life. The questionnaire was validated using 149 normal subjects. Chronbach alpha was 0.86. Test retest reliability was evaluated with 72 normal subjects, the correlation coefficient was 0.93. Discriminate validity was determined to be significant using the normal subject questionnaires and 10 questionnaires from subjects with recurrent SBO. Normative and level of impact for each measured domain were established using one standard deviation from the mean in the normal population and clinical relevance. This questionnaire is a valid and reliable instrument to measure the impact of SBO on a patient’s quality of life related to recurrent SBOs; therefore establishing a mechanism to monitor and quantify changes in quality of life over time.

Full Text Available Abstract Background Although the authors of a Cochrane Review on seclusion and mechanical restraint concluded that "there is a surprising and shocking lack of published trials" on coercive interventions in psychiatry, there are only few instruments that can be applied in trials. Furthermore, as main outcome variable safety, psychopathological symptoms, and duration of an intervention cannot meet the demand to indicate subjective suffering and impact relevant to posttraumatic stress syndromes. An instrument used in controlled trials should assess the patients' subjective experiences, needs to be applicable to more than one intervention in order to compare different coercive measures and has to account for the specific psychiatric context. Methods The primary version of the questionnaire comprised 44 items, nine items on restrictions to human rights, developed on a clinical basis, and 35 items on stressors, derived from patients' comments during the pilot phase of the study. An exploratory factor analysis (EFA using principal axis factoring (PAF was carried out. The resulting factors were orthogonally rotated via VARIMAX procedure. Items with factor loadings less than .50 were eliminated. The reliability of the subscales was assessed by calculating Cronbach. Results Data of 102 patients was analysed. The analysis yielded six factors which were entitled "Humiliation", "Physical adverse effects", "Separation", "Negative environment", "Fear" and "Coercion". These six factors explained 54.5% of the total variance. Cronbach alpha ranged from .67 to .93, which can be interpreted as a high internal consistency. Convergent and discriminant validity yielded both highly significant results (r = .79, p Conclusions The "Coercion Experience Scale" is an instrument to measure the psychological impact during psychiatric coercive interventions. Its psychometric properties showed satisfying reliability and validity. For purposes of research it can be used to compare different coercive interventions. In clinical practice it can be used as a screening instrument for patients who need support after coercive interventions to prevent consequences from traumatic experiences. Further research is needed to identify possible diagnostic, therapeutic or prognostic implications of the total score and the different subscales.

Abstract in english CONTEXT AND OBJECTIVE: Rheumatoid arthritis is a chronic systemic disease that causes joint damage. A variety of methods have been used to evaluate the general health status of these patients but few have specifically evaluated the hands. The objective of this study was to translate, perform cultu [...] ral adaptation and assess the validity of the Michigan Hand Outcomes Questionnaire for Brazil. DESIGN AND SETTING: Validation study conducted at a university hospital in Curitiba, Brazil. METHODS: Firstly, the questionnaire was translated into Brazilian Portuguese and back-translated into English. The Portuguese version was tested on 30 patients with rheumatoid arthritis and proved to be understandable and culturally adapted. After that, 30 patients with rheumatoid arthritis were evaluated three times. On the first occasion, two evaluators applied the questionnaire to check inter-rater reproducibility. After 15 days, one of the evaluators reassessed the patients to verify intra rater reproducibility. To check the construct validity at the first assessment, one of the evaluators also applied other similar instruments. RESULTS: There were strong inter and intra rater correlations in all the domains of the Michigan Hand Outcomes Questionnaire. Cronbach's alpha was higher than 0.90 for all the domains of the questionnaire, thus indicating excellent internal validity. Almost all domains of the questionnaire presented moderate or strong correlation with other instruments, thereby showing good construct validity. CONCLUSION: The Brazilian Portuguese version of the Michigan Hand Outcomes Questionnaire was translated and culturally adapted successfully, and it showed excellent internal consistency, reproducibility and construct validity.

Assessing PA may be difficult. Few PA questionnaires have been compared to activity monitors. We examined reproducibility and validity of the self-administered Longitudinal Ageing Study Amsterdam Physical Activity Questionnaire (LAPAQ against a triaxial accelerometer (ACTR (Sensewear® Pro in older adults.Methods: Participants wore the ACTR continuously for two weeks. After 2 (T [time] = 1 and 4 (T = 2 weeks, participants completed the LAPAQ. Since the LAPAQ asks about 2 weeks’ worth of physical activity, the ACTR and LAPAQ coincided at T1. T2 was used to assess the reproducibility of the LAPAQ results only. We calculated Pearson’s correlation coefficients (PCC to examine reproducibility and validity. For visualization, we used scatterplots and Bland–Altman plots. With a receiver operating characteristics (ROC curve we assessed how well the LAPAQ identifies older adults whose activity level is below official recommendations.Results: A total of 89 persons were included. Of the participants, 48% were men; median age was 73, and median body mass index was 25. The 2-week mean total duration of activity was 2788 (ACTR, T = 1, 2439 (LAPAQ T = 1, and 1994 (LAPAQ T = 2 minutes. As a reference, 2 full weeks contained 20,160 minutes. Reproducibility of the LAPAQ was moderate (PCC 0.68, 95% CI 0.55–0.80. The median difference between LAPAQ at T = 1 and the ACTR (LAPAQ minus ACTR was –510 minutes and the PCC was 0.25 (95% CI 0.07–0.44. The area under the ROC curve was 0.73 (95% CI 0.59–0.86.Conclusion: LAPAQ underestimates PA and seems unsuitable for exact measurement in older adults. However, it may be used to determine if a person’s PA level is below the recommended level.Keywords: physical activity, elderly, validation, questionnaire, accelerometer
Full Text Available Abstract Background Arrhythmias can appear with a variety of symptoms, all from vague to pronounced and handicapping symptoms. Therefore, patient-reported outcomes (PROs concerning symptom burden are important to assess and take into consideration in the care and treatment of patients with arrhythmias. The main purpose was to develop and validate a disease-specific questionnaire evaluating symptom burden in patients with different forms of arrhythmias. Methods A literature review was conducted and arrhythmia patients were interviewed. Identified symptoms were evaluated by an expert panel consisting of cardiologists and nurses working daily with arrhythmia patients. SF-36 and Symptoms Checklist (SCL were used in the validation of the new questionnaire Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia (ASTA. Homogeneity was evaluated with Spearman´s correlations and Cronbach´s alpha coefficient (? was used to evaluate internal consistency. Construct validity was evaluated using item-total correlations and convergent and discriminant validity. For this, Spearman´s correlations were calculated between the ASTA symptom scale, SCL and SF-36. Concurrent validity was validated by Spearman´s correlations between the ASTA symptom scale and SCL. Results The correlations between the different items in the ASTA symptom scale showed generally sufficient homogeneity. Cronbach´s coefficient was found to be satisfactory (??=?0.80; lower bound 95?% CI for ??=?0.76. Construct validity was supported by item-total correlations where all items in the symptom scale were sufficiently correlated (?0.3. Convergent and discriminant validity was supported by the higher correlations to the arrhythmia-specific SCL compared to the generic SF-36. Concurrent validity was evaluated and there were sufficiently, but not extremely strong correlations found between the ASTA symptom scale and SCL. Conclusions The nine items of the ASTA symptom scale were found to have good psychometric properties in patients with different forms of arrhythmias. Arrhythmia patients suffer from both frequent and disabling symptoms. The validated ASTA questionnaire can be an important contribution to PROs regarding symptom burden in arrhythmia patients.
Full Text Available Background: The measurement of psychosocial risk among workers is becoming increasingly important. Aim: To adapt, validate and standardize a questionnaire to measure psychosocial risks in the workplace. Material and Methods: The Spanish version of the Copenhagen Psychosocial Questionnaire was adapted and evaluated. Its contents were first validated with a panel of experts. Afterwards a semantic adaptation of the questionnaires was carried out applying it to a pilot sample. Finally, it was applied to 1,557workers (65% men. Results: A preliminary questionnaire containing 97 questions was constructed. A good item-test correlation was found, the factorial structure was similar to the original questionnaire and it had a good internal consistency, convergent validity with the Goldberg Health Questionnaire and test-retest correlation. Ranges for the different dimensions and sub-dimensions of psychosocial risk were calculated by tertiles. Conclusions: The resulting questionnaire is useful for measuring psychosocial risk factors at work, with good psychometric properties.
Background In Iranian Traditional Medicine, mizaj (temperament) plays a key role in preventive, therapeutic and lifestyle recommendations. A reliable self-reported scale for mizaj identification is critically needed to introduce ITM into the official medical and health care system especially in the case of designing national preventive protocols. Objectives The present study aimed to design a preliminary self-administered mizaj questionnaire and assessed its reliability and validity in Iran. Patients and Methods In this cross-sectional study, a questionnaire with 52 items was designed based on mizaj-related indices. Subsequent to content and face validity assessment, using qualitative and quantitative method, 47 items remained. Based on the non-randomly sampling, the test-retest reliability of each question and internal consistency of the questionnaire was examined by the participation of 35 volunteers. The reliable version questionnaire was filled up by 52 volunteers wherein they were divided into warm/cold and wet/dry groups based on their mizaj which was predetermined by a team of expert practitioners. Logistic regression analysis was performed for validity process between the experts’ assessment of mizaj and each of the items in the questionnaire that resulted to the final ten-item questionnaire divided into two subscales. By using ANOVA and post Hoc with Dunnet statistics, the optimum cut-off points were defined and their sensitivity and specificity was assessed. Results The weighted kappa coefficients of the 39 items were between 0.40 and 0.82 showing their acceptable reliability and the Cronbach’s ? coefficient was 0.71 showing the internal consistency. The sensitivity and specificity of the final questionnaire cut-off points were 65% and 93% for the warm group, 52% and 97% cold group, 53% and 67% dry group and finally 53% and 76% wet group. Conclusions Our results suggested that many of the designed questions according to the literature’s mizaj identification indices had satisfactory reliability and the final ten-item questionnaire could discriminate the different groups of mizaj, therefore, this can be used as the first version of a brief self-report mizaj estimating scale.

Full Text Available Abstract Background This article describes the development and validation of a self-reported questionnaire, the KQoL-26, that is based on the views of patients with a suspected ligamentous or meniscal injury of the knee that assesses the impact of their knee problem on the quality of their lives. Methods Patient interviews and focus groups were used to derive questionnaire content. The instrument was assessed for data quality, reliability, validity, and responsiveness using data from a randomised trial and patient survey about general practitioners' use of Magnetic Resonance Imaging for patients with a suspected ligamentous or meniscal injury. Results Interview and focus group data produced a 40-item questionnaire designed for self-completion. 559 trial patients and 323 survey patients responded to the questionnaire. Following principal components analysis and Rasch analysis, 26 items were found to contribute to three scales of knee-related quality of life: physical functioning, activity limitations, and emotional functioning. Item-total correlations ranged from 0.60–0.82. Cronbach's alpha and test retest reliability estimates were 0.91–0.94 and 0.80–0.93 respectively. Hypothesised correlations with the Lysholm Knee Scale, EQ-5D, SF-36 and knee symptom questions were evidence for construct validity. The instrument produced highly significant change scores for 65 trial patients indicating that their knee was a little or somewhat better at six months. The new instrument had higher effect sizes (range 0.86–1.13 and responsiveness statistics (range 1.50–2.13 than the EQ-5D and SF-36. Conclusion The KQoL-26 has good evidence for internal reliability, test-retest reliability, validity and responsiveness, and is recommended for use in randomised trials and other evaluative studies of patients with a suspected ligamentous or meniscal injury.

Chronic graft-versus-host disease (cGVHD) associated morbidity and mortality remain major barriers for successful allogeneic hematopoietic stem cell transplantation (alloHSCT). Currently, no reliable measures are established to monitor cGVHD activity changes for use in clinical trials. The Human Activity Profile (HAP) patient self-report was proposed by the National Institutes of Health (NIH) cGVHD consensus project as an independent measure of patients' functional status that could also indirectly reflect improvement of cGVHD, but that has not been validated in an alloHSCT patient population. One hundred seventy-six patients (median age 44 years [range: 18-72 years] after alloHSCT were evaluated with a German translation of the HAP, the NIH criteria-based cGVHD activity assessment, the Lee cGVHD Symptom-Scale, FACT-BMT, SF36, Berlin Social Support Scale, 24-Item Adjective Measure (24-AM), Hospital Anxiety and Depression Scale, and the NCCN-Distress-Thermometer. Enrollment occurred a median of 286 (range: 85-4003) days after alloHSCT. Follow-up surveys were conducted at 1, 2, 3, 5, 8, and 12 months after the baseline survey. Although 117 patient had cGVHD at time of enrollment (mild n = 33, moderate n = 50, or severe n = 34), 59 patients were included into the study in the absence of cGVHD between days 85 and 395 after transplantation. The maximum activity score (MAS) and adjusted activity score (AAS) of the HAP correlated inversely with grading of cGVHD severity (mild, moderate, or severe) (r = -0.25 for MAS and -0.24 for AAS). Lung manifestations of cGVHD correlated with AAS (r = 0.17), but not with MAS. HAP scores correlated with subscales from other instruments measuring physical domains, especially the physical functioning scale of the SF36. Performance was improved by use of an HSCT-modified HAP scoring system that excluded activities prohibited within the first year after alloHSCT. No significant correlation of the HAP was found with personality, age, sex, symptom burden, or social functioning or social well-being. Moreover, the HAP displayed a higher sensitivity to change of cGVHD activity compared to the SF36 and the FACT-BMT. In addition, steroid myopathy correlated with both HAP scores, but not the SF36. The HAP is a simple and valid questionnaire for the evaluation of the physical activity in patients after alloHSCT, with the advantage of detecting changes in cGVHD status independently of other quality-of-life measures and with a superior sensitivity compared to the SF36.

Introduction This paper describes the translation and psychometric evaluation of the Dutch Individualized Neuromuscular Quality of Life (INQoL) questionnaire. Methods Backward and forward translation of the questionnaire was executed, and psychometric properties were assessed on the basis of reliability and validity. Results 206 patients were included in the study. Reliability analyses resulted in Cronbach alpha values above 0.70 for all sub-domains. Known group validity showed a significant correlation between INQoL scores and severity as well as age for the majority of sub-domains. Item-total correlation for overall QoL was satisfactory. Concurrent validity with SF-36 and EQ-5D was good (range, Spearman correlation coefficients: -0.43 to -0.76). Conclusion This study resulted in a questionnaire which is appropiate for use in the Dutch-speaking population to measure quality of life of patients with a wide variety of muscle disorders. This confirms and extends data obtained in the United Kingdom, US, Italy, and Serbia. © 2014 Wiley Periodicals, Inc. PMID:25042897

The patient-doctor relationship (PDR) as perceived by the patient is an important concept in primary care and psychotherapy. The PDR Questionnaire (PDRQ-9) provides a brief measure of the therapeutic aspects of the PDR in primary care. We assessed the internal and external validity of the German version of the PDRQ-9 in a representative cross-sectional German population survey that included 2,275 persons aged?14 years who reported consulting with a primary care physician (PCP). The acceptance of the German version of this questionnaire was good. Confirmatory factor analysis demonstrated that the PRDQ-9 was unidimensional. The internal reliability (Cronbach's ?) of the total score was .95. The corrected item-total correlations were?.94. The mean satisfaction index of persons with a probable depressive disorder was lower than that of persons without a probable depressive disorder, indicating good discriminative concurrent criterion validity. The correlation coefficient between satisfaction with PDR and satisfaction with pain therapy was r?=?.51 in 489 persons who reported chronic pain, indicating good convergent validity. Despite the limitation of low variance in the PDRQ-9 total scores, the results indicate that the German version of the PDRQ-9 is a brief questionnaire with good psychometric properties to assess German patients' perceived therapeutic alliance with PCPs in public health research.

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Introducción: Ha sido demostrada una relación inversa entre los niveles de licopeno en el organismo y la aparición de algunas enfermedades crónico-degenerativas. Los cuestionarios de frecuencia de consumo de alimentos son una de las herramientas más utilizadas en los estudios epidemiológicos para es [...] timación de la ingestión de nutrientes. La necesidad de validación previa a su utilización constituye su principal inconveniente. La validación de un cuestionario de frecuencia de consumo de licopeno, adaptado a la población de las Islas Canarias, es el objetivo del presente trabajo. Material y métodos: Se diseñó un cuestionario semi-cuantitativo de frecuencia de consumo de alimentos, en el que fueron incluidos alimentos con elevado contenido en licopeno. El cuestionario fue aplicado a un grupo de 70 pacientes del Servicio de Cirugía Plástica del Hospital Universitario Insular de Gran Canaria. Se utilizó como patrón de oro, para su validación, los niveles séricos de licopeno de la población encuestada, determinados mediante la técnica de HPLC. Resultados: Se encontró una correlación directa entre la ingesta de alimento y los niveles en sangre del carotenoide, siendo el coeficiente de correlación de Spearman estimado 0,421. Se observó una asociación de los niveles de licopeno en sangre con la obesidad y algunas patologías, aunque no fue estadísticamente significativa. Conclusiones: La correlación obtenida entre la ingesta de alimentos conteniendo licopeno y los niveles séricos del micronutriente medidos, indica la validez del cuestionario y permite su utilización en estudios epidemiológicos. Abstract in english 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 drawba [...] ck 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.

Full Text Available Abstract Background The QUALIOST® was designed for use with the SF-36 to measure established osteoporosis-specific quality of life (QoL. The reliability (internal consistency and test-retest and validity of the questionnaire were established in a stand-alone psychometric validation study. The objective of this paper is to provide additional information on the instrument's responsiveness using clinical trial data, along with the reliability and validity of translated versions. Methods The Spinal Osteoporosis Therapeutic Intervention (SOTI was an international clinical trial comparing strontium ranelate to placebo on the occurrence of new vertebral fracture in patients with postmenopausal osteoporosis. QoL was a secondary endpoint, assessed using the SF-36 and QUALIOST® at baseline and every six months, with the main analysis at 3-year follow-up. Questionnaire acceptability, analysis of the hypothesised structure, internal consistency reliability and responsiveness to clinical change over time were assessed at the 3-year follow up. Results 1592 patients from 11 countries completed at least one QoL questionnaire. The psychometric properties of the questionnaires were assessed on cross-sectional (N = 1486 and longitudinal (N = 1288 data. Item discriminant validity of the QUALIOST® was excellent, as was item convergent validity, with 100% of item-scale correlations being above the 0.40 level. Internal consistency reliability was also extremely good, with high Cronbach's alpha scores above the 0.70 benchmark. Responsiveness results were consistent for all QUALIOST® scores, indicating that greater decreases in QoL corresponded to greater numbers of fractures experienced. QUALIOST® scores also differed according to the type of fracture suffered. This was demonstrated by increased effect sizes for more severe vertebral fractures (clinical vertebral and painful vertebral. In comparing responsiveness, the QUALIOST® scores were generally more consistent than those of the SF-36. Most notably, the QUALIOST® was more responsive with regard to painful vertebral fractures than the SF-36. Conclusion The QUALIOST® is a reliable and valid tool for measuring QoL in postmenopausal osteoporotic women. Being available in several validated language versions, it is ready to be used in a variety of settings, including international clinical trials.
Background. Caregivers are often involved in and affected by the patient's disease. The questionnaire 'Cancer Caregiving Tasks, Consequences and Needs Questionnaire' (CaTCoN) was developed to measure caregivers' experiences. The aim of this study is to evaluate the construct validity and reliability of the multi-item scales in the CaTCoN using psychometric analyses as well as tests of convergent and discriminant validity with the existing instruments FAMCARE and Family Inventory of Needs (FIN). Material and methods. Based on theoretical considerations, a subscale structure in the CaTCoN was hypothesized, and the subscales were tested by item-item correlations, followed by factor analysis, calculation of internal consistency by Cronbach's alpha, and multitrait-scaling analysis. Further, theoretically based hypotheses about convergence and divergence between CaTCoN and FAMCARE/FIN (sub)scales were formulated and tested. Results. Analyses were based on 590 caregivers' responses. Initially, 11 CaTCoN subscales were hypothesized. The item-item correlations and factor analysis lead to some revisions, but the analyses confirmed the hypothesized subscales to a large extent, resulting in nine CaTCoN subscales (Cronbach's alpha range 0.65-0.95). The hypothesized convergent CaTCoN and FAMCARE/FIN subscales correlated 0.59-0.74, and hypothesized divergent CaTCoN and FAMCARE/FIN subscales correlated -0.11-0.25, thus confirming the hypotheses concerning convergent and discriminant validity between CaTCoN and the existing questionnaires FAMCARE and FIN. Conclusion. Taken together the psychometric analyses and tests of convergent and discriminant validity indicate that the validity and reliability of the CaTCoN are satisfactory.

BACKGROUND: The number of adults living with cystic fibrosis (CF) is increasing, necessitating an assessment of knowledge in this growing population. METHODS: A questionnaire assessing CF knowledge was completed by 100 CF patients (median age: 26.0 years, range 17-49 years; median FEV: 57.0% predicted, range 20-127% predicted). Level of knowledge was correlated with clinical and sociodemographic characteristics. RESULTS: Questionnaire validation showed acceptable internal consistency (alpha=0.75) and test-retest reliability (0.94). Patients had fair overall understanding of CF (mean=72.4%, SD=13.1), with greater knowledge of lung and gastrointestinal topics (mean=81.6%, SD=11.6) than reproduction and genetics topics (mean=57.9%, SD=24.1). Females and those with post-secondary education scored significantly higher (p<0.05). CONCLUSIONS: This study validated a questionnaire that can be utilized to assess CF knowledge. Although CF patients understand most aspects of their disease, knowledge deficits are common - particularly regarding genetics and reproduction - and should be considered when developing CF education programs.

Drugs need to be evaluated both in terms of efficacy, safety and regarding the patient's perception of his own health status. For these reasons, sensible, reliable and patient-oriented instruments are needed, besides the methodologies for evaluation of drug efficacy and safety. Such instruments substantially evaluate Health related Quality of Life (HrQoL). Concerning gastric acid hypersecretion few papers are available, based on HrQoL questionnaires, both general and specific. A research project led us to develop through patients and physicians involvement, a specific instrument to evaluate HrQoL as to the various aspects of the peptic disease. The project started in 1993 through a series of 4 focus groups with gastroenterologists and patients, followed by the preparation of a questionnaire named QPD48. Such instrument was psychometrically validated through a study named Herqules 1, involving 176 gastroenterologists and 1774 patients. The psychometric analysis on QPD48 led to the re-issue of a questionnaire named QPD32 with Chronbach's alfa equal to 0.91, based on 3 factor-referenced subscales evaluating pain, induced anxiety, constrained daily living and awareness of symptoms and agents. Concerning the concurrent validity a one-way analysis of variance showed highly significant differences associated with attack frequency with substantial effect sizes ranging from 0.46 to 1.27 of a standard deviation in the full scale. QPD 32 is patent protected and will be used in clinical trials. PMID:8664414

Expressed emotion (EE) has proved to be an established factor in short-term relapse in schizophrenia. The aim of the present study was to examine the psychometric properties of the Greek version of the Family Questionnaire (FQ), a brief self-report questionnaire measuring the EE status of relatives of patients with schizophrenia in terms of criticism (CC) and emotional overinvolvement (EOI). The translated and adapted 20-item FQ was administered to 176 family caregivers of patients with schizophrenia and bipolar disorder. Caregivers' burden (Family Burden Scale) and psychological distress (General Health Questionnaire-28) were also evaluated. The findings indicated that the Greek version displays a two-factor structure with two subscales of EE-CC and EOI-with 10 items each, similarly to the original version. The convergent validity of the subscales was highly supported by correlations with caregivers' burden and psychological distress. The Cronbach's ? coefficient measuring internal consistency for the two scales were 0.90 for CC and 0.82 for EOI. The test-retest correlation coefficients measuring reproducibility were 0.99 and 0.98 for CC and EOI, respectively. The Greek version of the FQ appears to be a valid and reliable instrument to be used in both research and clinical assessment of family EE. PMID:24636193

With increasing economic globalization, including health care, it is important to use standardized outcome measures applicable to a broad spectrum of patients in a wide array of countries. The purpose of this study was to verify construct and content validity and reliability of the Chinese version of the Patient-rated Wrist Evaluation Questionnaire (PRWE-Hong Kong version). The PRWE was translated into Chinese, and face validity was established by inviting experts and patients to participate in the panel review of the questionnaire. A correlation field study was performed using a convenience sample of 47 patients with wrist injuries. Patients were assessed at baseline and six weeks after the initial measurement. The following measures were taken: the Chinese version of the PRWE and the Medical Outcome Short Form (36) Health Survey (SF-36), Visual Analogue Scale (VAS) for pain, active wrist range of motion, grip strength, and the Jebsen Hand Function Test. Statistical analysis consisted of Pearson correlation coefficients (convergent validity), factor analysis (content validity), paired t-test (convergent validity), and the Cronbach alpha (internal consistency). Clinically relevant correlations existed between "Pain at rest" and the VAS "resting pain" (r=0.785, pKong version in wrist-injured patients. Internal consistency testing results suggested that item consistency within subset items was good and persisted over time. In conclusion, the Chinese version of the PRWE is a reliable and valid self-rated tool in measuring treatment outcome. It supplements traditional objective clinical measures and is potentially applicable in Hong Kong clinical settings. PMID:16473730

The purpose of this study was the psychometric testing of a questionnaire to assess nurses' opinions, subjective norms, perceived difficulties, and knowledge related to palliative care. The 63-item MOVE2PC Questionnaire was tested among 219 nurses in groups differing in education and experience. The intra-rater agreement was moderate to good (??>?.5?max ), and internal consistency was good (alpha?=?.77). Construct validity was demonstrated by between-groups differences in knowledge, opinions, and perceived difficulties. Responsiveness was shown by improved scores after an education program. Time of completion was 20 minutes, and 99% skipped at most five items, demonstrating feasibility. Findings support the usefulness of the instrument for assessing nurses' knowledge and views on palliative care. PMID:23813723

Full Text Available BACKGROUND: This study was planned to assess the validity and reliability of the Prolapsus-related Quality of Life (P-QOL Questionnaire in a selected group of Turkish women. METHODS: The study included a total of 218 women applied to the gynecology outpatient clinic of Gulhane Military Medical Academy. Validity was assessed with known-groups technique. To use this technique, participants were separated into two groups, as symptomatic and asymptomatic for pelvic organ prolapse. Study participants completed a questionnaire including questions regarding Prolapse Quality of Life (P-QOL, sociodemographic and other characteristics of women at the beginning of their visit. Participants were also examined using the Pelvic Organ Prolapse Quantification System (POP-Q. RESULTS: Cronbach?s alpha internal consistency reliability coefficients were 0.95 for role limitations, 0.89 for physical limitations, 0.83 for social limitations, 0.76 for personel relationships, 0.95 for emotions, 0.93 for sleep/ energy, 0.64 for severity measures and 0.92 for total P-QOL. Spearman?s correlation coefficient between prolapsus-related quality of life domain?s scores and vaginal examination findings ranged from 0.10 to 0.46 (p<0.001. CONCLUSION: The Turkish translated version of the P-QOL is a reliable, consistent and valid instrument for assessing symptom severity, impact on quality of life in women with uterovaginal prolapse.

Stress is an increasingly important occupational health problem, even in developing countries suc as the Islamic Republic of Iran. The Job Content Questionnaire (JCQ) is a widely used self-administered to measure dimensions of job stress in the workplace. This study describes the preparation of a Persian (Farsi) language version of the questionnaire (P-JCQ). In the first stage, linguistic validation was done by forward and backward translation. In the psychometric evaluation stage, the reliability and validity of the P-JCQ were explored among 107 hospital nurses in Shiraz city. Cronbach alpha coefficients for decision latitude and psychological job demands scales were 0.54 and 0.58 respectively and ranged from 0.64 to 0.85 for other scales. Exploratory factor analysis showed 3 meaningful factors that could explain support, psychological job demands and physical loads and hazard exposure. The P-JCQ has satisfactory linguistic validity and psychometric properties, provided the recommended factor pattern is used. PMID:22259893

The aim of this study was to develop and validate a short form of the Brazilian version of McGill Pain Questionnaire (SF-MPQ). Three hundred two patients with chronic pain filled out the validated Brazilian long form of the McGill Pain Questionnaire (LF-MPQ). Words chosen by ?25% of the patients were selected to comprise the SF-MPQ. The Brazilian SF-MPQ consisted of 15 descriptors (8 sensory, 5 affective, and 2 evaluative) rated on a binary mode (present or absent). Four pain scores were derived by counting the words chosen by the patients for sensory, affective, evaluative, and total descriptors. The SF-MPQ showed poor internal consistency (KR-20 = 0.52) but possibly acceptable because it showed discriminant validity to discriminate patients presenting different levels and mechanisms of pain, and it was strongly correlated with the LF-MPQ. The low KR-20 coefficient could result from the small number of items. The Brazilian version of the SF-MPQ proved to be a useful instrument to evaluate the different qualities of pain. It is a reliable option to the long-form MPQ. PMID:24315244

Full Text Available The utility of The SF-36 questionnaire for evaluation of health related quality of life was not clear in elderly people. The Cross-Sectional study was designed and Iranian version of The SF-36 was administered to random sample of 100 old subjects over 60 years old. Finding showed good internal consistency over 0.7 for all subscales of questionnaire. Convergent validity was obtained for all subscales with comparison for General Health Questionnaire-28 (GHQ-28 but was not strongly at 2 subscales Role emotional and Role physical. Discriminant validity was addressed for gender but for age groups role emotional, mental health and general health subscales were not different significantly. A principal component analysis was leaded one factor structure. Evidence for reliability of the questionnaire was good. But validity appeared moderate satisfactory. However this questionnaire seems the only measure for assessment of health related quality at life among elderly population.
BackgroundThe PEmb-QoL is a validated 40-item questionnaire to quantify health-related quality of life in patients having experienced pulmonary embolism (PE). It covers six health dimensions: frequency of complaints, activities of daily living limitations, work-related problems, social limitations, intensity of complaints, and emotional complaints. Originally developed in Dutch and English, we sought to prospectively validate the psychometric properties of a French version of the PEmb-QoL.MethodsWe performed a forward and backward translation of the English version of the PEmb-QoL into French. French-speaking consecutive adult patients with an acute, objectively confirmed PE admitted to the emergency department of a Swiss university hospital between 08/2009 and 09/2011 were recruited telephonically. We used standard psychometric tests and criteria to evaluate the acceptability, reliability, and validity of the French version of the PEmb-QoL. We also performed an exploratory factor analysis.ResultsOverall, 102 patients were enrolled in the study. The French version of the PEmb-QoL showed good reliability (internal consistency, item¿total and inter-item correlations), reproducibility (test-retest reliability), and validity (convergent, discriminant) in French-speaking patients with PE. The exploratory factor analysis suggested three underlying dimensions: limitations in daily activity (items 4b-m, 5a-d), symptoms (items 1a-h and 7), and emotional complaints (items 9a-f and j).ConclusionWe successfully validated the French version of the PEmb-QoL questionnaire in patients with PE. Our results show that the PEmb-QoL is a valuable tool for assessing health-related quality of life after PE in French-speaking patients. PMID:25464821

BACKGROUND Symptoms of gastro-esophageal reflux disease (GERD) affect health-related quality of life (HRQOL). When a questionnaire is translated into a new language, linguistic validation is necessary, yet insufficient, unless the psychometric characteristics have been verified. The aim of this study is to document the translation and psychometric validation of the Persian translation of the Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire. METHODS After translation and cultural adaptation of QOLRAD to Persian, fifty patients with clinical GERD from the Prospective Acid Reflux Study of Iran (PARSI) database who had at least one of the symptoms of acid regurgitation, heartburn, non-cardiac chest pain, or dysphagia for at least four weeks over the past three months completed the QOLRAD and Short Form Health Survey-36 (SF-36). After two weeks, QOLRAD was again completed by the patients. Cronbach alpha and Intra-class Correlation Coefficient (ICC) were used to test reliability and Pearson correlation was used to compare the dimensions of SF-36 and QOLRAD. RESULTS The translation was approved by MAPI Research Institute. Fifty patients completed the SF-36 and QOLRAD questionnaires at the first visit. Mean (SD) age of the participants was 38.4 (14.6) years and 68% were females. The internal consistency and reliability of QOLRAD ranged from 0.78-0.92. The test-retest reliability of QOLRAD was from 0.87-0.93. Relevant QOLRAD domains significantly correlated with the majority of SF-36 domains, with the exception of sleep disturbance. CONCLUSION The psychometric characteristics of the Persian translation of QOLRAD were found to be good, with satisfactory reliability and validity. PMID:25197518
