Successful weight management relies on at least two health behaviors, eating and exercise. However, little is known about their interaction on a motivational and behavioral level. Based on the Hierarchical Model of Motivation the authors examined whether exercise-specific motivation can transfer to eating regulation during a lifestyle weight control program. The authors further investigated whether general, treatment-related, and exercise motivation underlie the relation between increased exercise and improved eating regulation. Overweight/obese women participated in a 1-year randomized controlled trial (N = 239). The intervention focused on promoting physical activity and internal motivation for exercise and weight loss, following Self-Determination Theory. The control group received general health education. General and exercise specific self-determination, eating self-regulation variables, and physical activity behavior. General self-determination and more autonomous exercise motivation predicted eating self-regulation over 12 months. Additionally, general and exercise self-determination fully mediated the relation between physical activity and eating self-regulation. Increased general self-determination and exercise motivation seem to facilitate improvements in eating self-regulation during weight control in women. These motivational mechanisms also underlie the relationship between improvements in exercise behavior and eating regulation. PsycINFO Database Record (c) 2009 APA, all rights reserved.

The present study examined the role of adolescents' self-esteem and perceptions of family and classroom contexts on their domain specific self-perceptions. 345 Greek junior high school adolescents aged 14-16 completed measures of domain specific self-perceptions, self-esteem, parenting styles and classroom climate. Hierarchical regression analyses revealed that both family and classroom contexts predicted students' self-perceptions, after students' demographics, academic achievement and self-esteem were controlled for. However, different patterns emerged in the relationship between family, classroom climate and self-esteem depending on domain specific self-perceptions. Academic self-perceptions (scholastic, mathematics and language competences) were predicted by classroom climate dimensions (order and organization, student involvement, rule clarity), whereas self-perceptions regarding relations with parents, close friends and behaviour conduct, were predicted by parenting styles. Given the fact that adolescence is a period of fluctuation in self-understanding which renders self-perceptions particularly malleable, the results support the critical role of the social environments where adolescents operate.

2001-01-01

A study of two groups of female psychiatric inpatients, differing in level of ego development, explored domains of self-perception that best predicted global self-worth and symptom clusters that best predicted second-order factors of self perception. Findings revealed quantitative and qualitative differences in self-complexities, and more positive self-perceptions among the higher ego-level group in scholastic competence, job competence, and behavioral conduct. Results are discussed from a developmental perspective.

This study examined the impact of U.S. chain restaurant food consumption in China and South Korea from an ecological perspective. Specifically, it explored the relationships among several environmental and individual variables that have been found to affect obesity/weight management in previous research, including the prevalence/popularity of U.S. chain restaurants in these countries, frequency of U.S. chain restaurant food consumption, self-efficacy in weight management, willingness to communicate about weight/diet, self-perceptions of weight/obesity stigma, body mass index (BMI), and depression. The results indicated that willingness to communicate about weight/diet predicted increased self-efficacy in weight management. Higher BMI scores were found to predict increased weight/obesity stigma, and increased frequency of U.S. restaurant food consumption, weight/obesity stigma, and reduced self-efficacy in weight management were found to predict increased levels of depression. The theoretical and practical implications of the findings are discussed, along with limitations and directions for future research.

To compare weight concerns and self-reported body mass index (BMI) of low birth weight (LBW) adolescent boys to those of a normative sample and examine relationships among BMI, weight concerns, self-esteem, and depression in the LBW cohort. LBW boys (n = 260; mean age, 16.0) belong to the Neonatal Brain Hemorrhage Study birth cohort. Normative boys (n = 305; mean age, 16.5) belong to the National Health and Nutrition Examination Survey. Both samples were assessed in 2001-2004 with self-report questionnaires. BMI was calculated from self-reported height and weight. Weight perception and weight dissatisfaction were assessed with the Eating Symptoms Inventory. In LBW boys, self-esteem was measured with the Rosenberg Self-Esteem Scale and depression with the Beck Depression Inventory. Based on self-reported height and weight, LBW boys were more likely to be healthy weight or underweight and less likely to be overweight than normative boys. Despite having healthier self-reported BMIs, LBW boys reported more weight concerns than the normative sample. A total of 46.9% of LBW boys perceived their weight as abnormal, and 76.5% desired weight change. Weight concerns in LBW boys mostly reflected a perception of being underweight (31.2% of the cohort) and a desire to gain weight (47.5% of the cohort), although only 6.5% were clinically underweight. Weight concerns, but not BMI, were related to clinical depression and lower self-esteem. LBW adolescent boys are at high risk of experiencing weight concerns. Weight concerns rather than BMI are associated with emotional problems in LBW boys.

This study sought to identify the principal components of self-esteem and the health behavioural determinants of these components among grade five students. We analysed data from a population-based survey among 4918 grade five students, who are primarily 10 and 11 years of age, and their parents in the Canadian province of Nova Scotia. The survey comprised the Harvard Youth and Adolescent Questionnaire, parental reporting of students' physical activity (PA) and time spent watching television or using computer/video games. Students heights and weights were objectively measured. We applied principal component analysis (PCA) to derive the components of self-esteem, and multilevel, multivariable logistic regression to quantify associations of diet quality, PA, sedentary behaviour and body weight with these components of self-esteem. PCA identified four components for self-esteem: self-perception, externalizing problems, internalizing problems, social-perception. Influences of health behaviours and body weight on self-esteem varied across the components. Better diet quality was associated with higher self-perception and fewer externalizing problems. Less PA and more use of computer/video games were related to lower self-perception and social-perception. Excessive TV watching was associated with more internalizing problems. Students classified as obese were more likely to report low self- and social-perception, and to experience fewer externalizing problems relative to students classified as normal weight. This study demonstrates independent influences of diet quality, physical activity, sedentary behaviour and body weight on four aspects of self-esteem among children. These findings suggest that school programs and health promotion strategies that target health behaviours may benefit self-esteem in childhood, and mental health and quality of life later in life.

Underestimating one's weight is often seen as a barrier to weight loss. However, recent research has shown that weight underperception may be beneficial, with lower future weight gain and fewer depressive symptoms. Here, we examine the relationship between adolescent weight underperception and future blood pressure. Using data from the National Longitudinal Study of Adolescent to Adult Health, we obtained a nationally representative sample of 2,463 adolescents with overweight and obesity (students in grades 8-12 in 1996). We used multivariable linear regression to prospectively examine the relationship between weight self-perception in adolescence and blood pressure in adulthood (year 2008; follow-up rate 80.3%), controlling for age, gender, race/ethnicity, smoking, alcohol consumption, education level, household income, and body mass index. Additional analyses were stratified by gender and race/ethnicity. Youth with overweight/obesity who underperceived their weight had lower blood pressure in adulthood than those who perceived themselves to be overweight. The decrease in systolic blood pressure was -2.5 mm Hg (95% confidence interval: -4.3, -0.7; p = .006). Although the interaction by gender was statistically insignificant (p = .289), important differences appeared upon stratification by gender. Young men showed no significant difference in adult blood pressure related to weight self-perception. Conversely, in young women, weight underperception was associated with an average decrease in systolic blood pressure of -4.3 mm Hg (95% confidence interval: -7.0, -1.7; p = .002). Contrary to conventional wisdom, weight underperception is associated with improved health markers in young women. The observed differences in blood pressure are clinically relevant in magnitude, and interventions to correct weight underperception should be re-examined for unintended consequences.

Comparing Self-Report Measures of Internalized Weight Stigma: The Weight Self-Stigma Questionnaire versus the Weight Bias Internalization Scale.

Directory of Open Access Journals (Sweden)

Claudia Hübner

Full Text Available Internalized weight stigma has gained growing interest due to its association with multiple health impairments in individuals with obesity. Especially high internalized weight stigma is reported by individuals undergoing bariatric surgery. For assessing this concept, two different self-report questionnaires are available, but have never been compared: the Weight Self-Stigma Questionnaire (WSSQ and the Weight Bias Internalization Scale (WBIS. The purpose of the present study was to provide and to compare reliability, convergent validity with and predictive values for psychosocial health outcomes for the WSSQ and WBIS.The WSSQ and the WBIS were used to assess internalized weight stigma in N = 78 prebariatric surgery patients. Further, body mass index (BMI was assessed and body image, quality of life, self-esteem, depression, and anxiety were measured by well-established self-report questionnaires. Reliability, correlation, and regression analyses were conducted.Internal consistency of the WSSQ was acceptable, while good internal consistency was found for the WBIS. Both measures were significantly correlated with each other and body image. While only the WSSQ was correlated with overweight preoccupation, only the WBIS was correlated with appearance evaluation. Both measures were not associated with BMI. However, correlation coefficients did not differ between the WSSQ and the WBIS for all associations with validity measures. Further, both measures significantly predicted quality of life, self-esteem, depression, and anxiety, while the WBIS explained significantly more variance than the WSSQ total score for self-esteem.Findings indicate the WSSQ and the WBIS to be reliable and valid assessments of internalized weight stigma in prebariatric surgery patients, although the WBIS showed marginally more favorable results than the WSSQ. For both measures, longitudinal studies on stability and predictive validity are warranted, for example, for weight

Self-perception of intrinsic and extrinsic motivation.

Self-perception theory predicts that intrinsic and extrinsic motivation do not combine additively but rather interact. To test this predicted interaction, intrinsic and extrinsic motivation were both manipulated as independent variables. The results revealed a significant interaction for task satisfaction and a trend for the interaction on a behavioral measure. These results are discussed in terms of a general approach to the self-perception of motivation.

A mediational model of obesity related disordered eating: The roles of childhood emotional abuse and self-perception.

Hymowitz, Genna; Salwen, Jessica; Salis, Katie Lee

The extant literature indicates negative self-perceptions are a risk factor for disordered eating (DE) and DE is a risk factor for overweight and obesity. While childhood emotional abuse (EA) is often linked to DE and obesity, it is typically not included in comprehensive models of these health problems. Further investigation of interactions among EA, self-perception, and DE is needed to refine treatments for overweight, obesity, and DE. This study evaluated a model of DE and weight difficulties in which negative self-perception mediate the relationship between EA and DE, and DE predicts body mass index (BMI) in a population of emerging adults. Further, this study investigated the utility of history of EA for prediction of DE and classification of individuals with and without DE. Self-report questionnaires on childhood trauma, psychopathology, and eating behaviors were administered to 598 undergraduate students. Latent variable analysis confirmed the hypothesized model. Recursive partitioning determined that individuals reporting a high level of EA likely meet criteria for night eating syndrome (NES) or binge eating disorder (BED), and history of EA has a moderate to high level of specificity as a predictor of BED and NES. These findings confirm the necessity of evaluating EA and DE in emerging adults with weight difficulties, and the importance of assessing self-perception and DE in individuals with a history of EA. Future studies should investigate the utility of addressing EA and self-perception in interventions for DE and obesity and to determine whether these findings can be generalized to a clinical population.

This study used self-determination theory (Deci, E.L., & Ryan, R.M. (2000). The 'what' and 'why' of goal pursuits: Human needs and the self-determination of behavior. Psychological Inquiry, 11, 227-268.) to examine predictors of body image concerns and unhealthy weight control behaviours in a sample of 350 Greek adolescent girls. A process model was tested which proposed that perceptions of parental autonomy support and two life goals (health and image) would predict adolescents' degree of satisfaction of their basic psychological needs. In turn, psychological need satisfaction was hypothesised to negatively predict body image concerns (i.e. drive for thinness and body dissatisfaction) and, indirectly, unhealthy weight control behaviours. The predictions of the model were largely supported indicating that parental autonomy support and adaptive life goals can indirectly impact upon the extent to which female adolescents engage in unhealthy weight control behaviours via facilitating the latter's psychological need satisfaction.

Full Text Available Abstract Background Few studies have examined the association between weight perception and socioeconomic status (SES in sub-Saharan Africa, and none made this association based on education, occupation and income simultaneously. Methods Based on a population-based survey (n = 1255 in the Seychelles, weight and height were measured and self-perception of one's own body weight, education, occupation, and income were assessed by a questionnaire. Individuals were considered to have appropriate weight perception when their self-perceived weight matched their actual body weight. Results The prevalence of overweight and obesity was 35% and 28%, respectively. Multivariate analysis among overweight/obese persons showed that appropriate weight perception was directly associated with actual weight, education, occupation and income, and that it was more frequent among women than among men. In a model using all three SES indicators together, only education (OR = 2.5; 95% CI: 1.3-4.8 and occupation (OR = 2.3; 95% CI: 1.2-4.5 were independently associated with appropriate perception of being overweight. The OR reached 6.9 [95% CI: 3.4-14.1] when comparing the highest vs. lowest categories of SES based on a score including all SES indicators and 6.1 [95% CI: 3.0-12.1] for a score based on education and occupation. Conclusions Appropriately perceiving one's weight as too high was associated with different SES indicators, female sex and being actually overweight. These findings suggest means and targets for clinical and population-based interventions for weight control. Further studies should examine whether these differences in weight perception underlie differences in cognitive skills, healthy weight norms, or body size ideals.

To associate the nutritional status and the self-perception of nutritional status with the use of licit drugs among adolescents. Cross-sectional study in which 210 adolescents answered a questionnaire on alcohol and tobacco experimentation and self-perceptions about their nutritional status. The correspondence between the adolescents' perception of their own nutritional status and actual nutritional status was analyzed, as well as associations between nutritional status, self-perception of nutritional status, gender, age, and presence of smokers at home with alcohol and tobacco use. The variables were analyzed separately in a bivariate analysis and, subsequently, a multivariate analysis determined the factors associated with drug use. The study included 210 adolescents with a median age of 148 months; 56.6% were females. Of the total sample, 6.6% have tried cigarettes, and 20% have tried alcohol; 32.3% had BMI Z-Score≥1, 12.85% had BMI Z-Score≥2, and 50.7% had a correct perception of his/her weight. After a multivariate analysis, only the self-perception about weight statistically influenced experimentation of tobacco, and patients who identified themselves as having very high weight were more likely to experiment tobacco (odds ratio (OR) 13.57; confidence interval (95% CI) 2.05-89.8; p=0.007); regarding alcohol use, adolescents who identified themselves as having high weight were 2.4 times more likely to experiment with alcohol than adolescents that identified themselves as having normal weight (95% CI 1.08-5.32, p=0.031). Adolescents with self-perception of excess weight may constitute a risk group for alcohol and tobacco use. Copyright © 2015 Sociedade de Pediatria de São Paulo. Publicado por Elsevier Editora Ltda.

2016-02-01

Full Text Available Objective: An investigation of the interplay between various types of adolescents’ perceptions of weight status in predicting adolescents’ nutrition behavior and their body weight was conducted. In particular, it was hypothesized that the relationship between parental and peers’ perceptions of their own weight status (reported by adolescents and objectively measured weight status of adolescents would be mediated by three types of adolescents’ weight status perceptions (adolescents’ own weight perceptions, parental perceptions of adolescents’ weight status perceived by participants, and peers’ perceptions of adolescents’ weight status perceived by participants and by adolescents’ nutrition behaviors. Design: Data were collected twice, with a 13-month follow-up. Participants (N = 1096 were aged 14-20, with BMI ranging from 16.20 to 41.21. Multiple mediation analysis with two sequential mediators was applied.Main outcome measures: At the baseline adolescents completed the questionnaire assessing their nutrition behaviors and weight status perceptions. Weight and height were measured objectively at baseline and follow-up.Results: Two types of weight perceptions (adolescents’ own weight status perceptions, peers’ perceptions of adolescents’ weight status reported by participants, and adolescents’ nutrition behaviors mediated the relationship between the others’ own weight perceptions and adolescents’ weight status. No indirect effects of others’ own weight perceptions on adolescents’ weight status through parental perceptions were found.Conclusion: Adolescents’ nutrition behaviors and body weight status depend on what they think about their own weight status and what they think of their peers’ perceptions, but do not depend on what adolescents think of their parents’ perceptions.

Wen, X; Hui, S S C

2011-05-01

The purpose of this study is to examine Chinese parents' perceptions of their children's weights and explore the parenting behaviours associated with these perceptions. A total of 2143 adolescents and 1869 parents were recruited from secondary schools in Ganzhou and Shantou in China. The adolescents' actual weights and heights were measured by trained testers. The self-reported parents' weights and heights, parental perception of the adolescents' weights, adolescents' perception of their own weights, parenting behaviours and demographic information were collected through the questionnaires distributed to the respondents. The results based on Kappa statistics show only a slight agreement between parental perception of their children's weights and the adolescents' actual weights (Kappa = 0.221). The results from the logistic regression show that the parents' gender [odds ratio (OR) = 0.80, 95% confidence interval (CI): 0.64-1.00], adolescents' gender (OR = 1.61, 95% CI: 1.29-2.01) and perception of their own weights (OR = 0.30, 95% CI: 0.24-0.38) are associated with the parents' perception of their children's weights. Statistically significant difference in several parenting behaviours was found between the parents with correct and incorrect perceptions of their children's weight. Misconceptions about their children's weights are prevalent among Chinese parents. The association between parents' perception of their children's weight and parenting behaviours suggests that the accurate classification of children's weights could help prevent childhood obesity. © 2010 Blackwell Publishing Ltd.

Shaping of self-perception is among others influenced by physical, interpersonal, emotional, and cultural factors. In self-perception of overweight people an important role is played by interpersonal factors, which include the opinions of others and the relationship with the surrounding. The evaluation of the body image is also affect by sociocultural factors including the media, which create an unrealistic and impossible to achieve ideal of beauty. Contemporary ideal of beauty, where a slim figure is dominant, more frequently contributes to the occurrence of discrimination and stigmatization of overweight people. This phenomenon causes negative self-perception leading to the occurrence of such emotional problems as low self-esteem, lack of confidence, depression and anxiety disorders. Overweight children and adolescents are also frequently stigmatized and discriminated because of their body weight, which results in the development of a negative body image that may lead to low self-esteem and symptoms of depression.

The Effects of Weight Perception on Adolescents’ Weight-Loss Intentions and Behaviors: Evidence from the Youth Risk Behavior Surveillance Survey

2015-11-01

Full Text Available The objective of this study was to examine the correlation between self-perception of being overweight and weight loss intentions, eating and exercise behaviors, as well as extreme weight-loss strategies for U.S. adolescents. This study uses 50,241 observations from the Youth Risk Behavior Surveillance Survey (YRBSS 2001–2009, which were nationally representative sample of 9th- through 12th-grade students in both public and private schools in the US. This study finds that, irrespective of the weight status base on self-reported weight and height, adolescents who perceive themselves as overweight have a stronger intention to lose weight, but do not develop better eating and exercise habits, compared with their counterparts of same gender and reported weight status. Normal-weight adolescents, if they perceive themselves as overweight, are more likely to engage in health-compromising weight-loss methods. This study shows that it is critical to transform weight-loss intentions into actual behaviors among overweight/obese adolescents and improve the efficacy of behavioral interventions against childhood obesity. It also highlights the need of establishing a correct perception of body weight among normal weight adolescents to curb extreme weight-loss methods.

We examined the socio-economic differential in the self-perception of body weight, future intention for weight management and actual weight-management behaviour among normal-weight, overweight and obese women in India. A population-based follow-up survey of ever-married women, systematically selected from the second round of the National Family Health Survey (NFHS-2, 1998-99) samples, who were re-interviewed after four years in 2003. Information on women's perception about their own weight, intention of weight management and actual weight-management behaviour were collected through personal interview. Anthropometric measurements were obtained from women to compute their current BMI. Three hundred and twenty-five ever-married women aged 20-54 years residing in the national capital territory of Delhi in India. Discrepancy between self-perceived body weight and women's actual body weight was reported. One-quarter of overweight women and one in ten obese women perceived themselves as normal weight. Although a majority of overweight and obese women wanted to reduce their weight, a significant proportion of overweight (one in four) and 4 % of obese women also wanted to maintain their weight as it is. Only one in three overweight and one in four obese women were performing any physical activity to reduce their weight. These findings are important for public health interventions in obesity care. Implementation of health promotion and health education in the community should use effective school education and mass-media programmes to raise awareness of appropriate body weight to combat the growing level of obesity among Indian women.

Connecting Athletes’ Self-Perceptions and Metaperceptions of Competence: a Structural Equation Modeling Approach

Cecchini, Jose A.; Fernández-Rio, Javier; Méndez-Giménez, Antonio

2015-01-01

This study explored the relationships between athletes’ competence self-perceptions and metaperceptions. Two hundred and fifty one student-athletes (14.26 ± 1.89 years), members of twenty different teams (basketball, soccer) completed a questionnaire which included the Perception of Success Questionnaire, the Competence subscale of the Intrinsic Motivation Inventory, and modified versions of both questionnaires to assess athletes’ metaperceptions. Structural equation modelling analysis revealed that athletes’ task and ego metaperceptions positively predicted task and ego self-perceptions, respectively. Competence metaperceptions were strong predictors of competence self-perceptions, confirming the atypical metaperception formation in outcome-dependent contexts such as sport. Task and ego metaperceptions positively predicted athletes’ competence metaperceptions. How coaches value their athletes’ competence is more influential on what the athletes think of themselves than their own self-perceptions. Athletes’ ego and task metaperceptions influenced their competence metaperceptions (how coaches rate their competence). Therefore, athletes build their competence metaperceptions using all information available from their coaches. Finally, only task-self perfections positively predicted athletes’ competence self-perceptions. PMID:26240662

Full Text Available Background: Breast cancer is the most common type of cancer and second leading cause of death in women after lung cancer. The World Health Organization has reported that breast cancer, with 502,000 deaths in 2005, surpassed lung, stomach, colorectal, and cervical cancers as the leading cause of death in women. The main objective of the current study was to examine the predictive role of emotional selfregulation in quality of life and perception of suffering among patients with breast cancer. Methods: This was a descriptive-analytical study followed by a correlational design. The sample population consisted of 42 patients with breast cancer selected by the census method. Participants completed questionnaires on emotional self-regulation, quality of life (Aaronson et al., 1987, and perception of suffering. The obtained data was statistically analyzed using the Pearson correlation coefficient and regression analysis via SPSS 22. Results: There was a significant, positive association between emotional selfregulation and the functional and general dimensions of quality of life. A significant, inverse correlation existed between emotional self-regulation and the symptoms dimension of quality of life. The results of the enter regression analysis showed that selfregulation respectively predicted 0.18 of variance in the functional, 0.26 in symptoms, and 0.37 of the variance in the general health dimensions of the quality of life. Emotional self-regulation had a significant, diverse relationship to the physical, psychological, and existential dimensions of perception of suffering. The results of the regression analysis carried out to predict perception of suffering indicated that emotional self-regulation respectively predicted 0.33 of variance in the physical, 0.19 in psychological, and 0.06 of the variance in the existential dimensions of perception of suffering. Conclusion: A major step forward can be taken towards improving the level of quality of

Background Although obesity continues to rise and remains a great public health concern in the U.S., a number of important levers such as self-perception of weight and calorie postings at point-of-purchase in restaurants are still not well-characterized in the literature, especially for low-income and minority groups in Los Angeles County (LAC). To study this gap, we examined the associations of self-perception of weight (as measured by body weight discrepancy) with food choice intentions and...

We examined the cultural influence on perceived body weight and the level of health practices at a national and individual level. At a national level, we found that Japanese women (n = 80) overestimate body weight more than Korean (n = 82) and American (n = 63) women. At an individual level, individuals with interdependent self-construal were more prone to overestimate weight than those with independent self-construal (N = 182; American women). Based on the data, we identify that the relationship is mediated by self-criticism, and, importantly, it is self-criticism rather than perceived overweight that predicts the level of health activities. Health practitioners and campaign designers across cultures are recommended to concentrate on promoting positive body esteem instead of encouraging engagement in corrective health behaviors for weight loss.

Full Text Available Background: there is a growing interest in the study of the self-perceptions of children with Attention Deficit/Hyperactivity Disorder (ADHD and the bias in their self-concept. Goal: to explore how ADHD children’s perception of parenting style predicts their selfperception and the bias in self-concept. Method: Participants: children between 7 and 13 years old diagnosed with ADHD, children assisting to psychotherapy without an ADHD diagnose, and children not assisting to psychotherapy. It also participated one of their parents. Data analysis: It was used simple logistic regressions. Groups were studied separately. Results: maternal pathological control was the main predictor of ADHD children’s positive self-perceptions and bias. In the comparison groups it predicts negative self-perceptions. Results are discussed in the light of self-protection hypothesis.

Approximately one-third of children in the USA are either overweight or obese. Understanding the perceptions of children is an important factor in reversing this trend. An online survey was conducted with children to capture their perceptions of weight, overweight, nutrition, physical activity and related socio-behavioural factors. Within the USA. US children (n 1224) aged 8-18 years. Twenty-seven per cent of children reported being overweight; 47·1% of children overestimated the rate of overweight/obesity among US children. A higher percentage of self-classified overweight children (81·9%) worried about weight than did self-classified under/normal weight children (31·1%). Most children (91·1%) felt that it was important to not be overweight, for both health-related and social-related reasons. The majority of children believed that if someone their age is overweight they will likely be overweight in adulthood (93·1%); get an illness such as diabetes or heart disease in adulthood (90·2%); not be able to play sports well (84·5%); and be teased or made fun of in school (87·8%). Children focused more on food/drink than physical activity as reasons for overweight at their age. Self-classified overweight children were more likely to have spoken with someone about their weight over the last year than self-classified under/normal weight children. Children demonstrated good understanding of issues regarding weight, overweight, nutrition, physical activity and related socio-behavioural factors. Their perceptions are important and can be helpful in crafting solutions that will resonate with children.

Full Text Available Abstract Background: Today, overweight is a damaging agent that threats general health and mental states. So, the current research was done with the aim of specifying the relationship between personality attributes (neuroticism, psychoticism, self-efficacy in weight control with people’s weight. Materials and Methods: This was a descriptive - correlational study. The sample concluded of all of students in Razi university of Kermanshah in year 2015-2016; of them 459 people were selected with stochastic random sampling method. The research tools were self-efficacy of lifestyle that effects on weight and Eisenck personality questionnaires. Results: The results showed that there is a negative significant relationship between weight with neuroticism and psychotics (p<0.001, but there was no significant relationship between neuroticism and weight. Also, the results showed that the components of self-efficacy in weight control can predict weight of people. Based on this, overeating with impact factor equal to 0.001, diet with 0.28 and oral inhibition with -0.13 of impact factor can predict weight of people. Conclusion: Due to the results, psycho personality and self-efficacy have roles in weight control of people.

Self-care practices among persons living with type-2 diabetes are very crucial in diabetes manages as poor self-care results in complications. However, little research exists within the Ghanaian context. This study examined whether type-2 diabetes patients' illness perception and diabetes knowledge significantly predict diabetes self-care practices. A cross-sectional survey design was employed and a total of 160 participants (45 males and 115 females) were sampled from a general hospital in Accra. A self-administered questionnaire measuring illness perception, diabetes knowledge and diabetes self-care practices as well as demographic checklist were used collect data. Results showed that illness perception and diabetes knowledge significantly predicted overall diabetes self-care practices. Analysis of domain specific self-care practices showed that patients' diet was significantly predicted by illness perception and diabetes knowledge. Exercise was significantly predicted by only illness perception while blood sugar testing and diabetes foot-care were significantly predicted by diabetes knowledge. Cognitive and emotional representation of diabetes and diabetes knowledge are key determinants of patients' diabetes self-care practices. It is therefore important that appropriate psychosocial interventions are developed to help patients' adherence to recommended self-care practices.

Self-perception of voice has a significant psychosocial impact on transgender persons. Research about the evolution of self-perception of voice during cross-sex hormone therapy (CSHT) is lacking. The aim of this study was to examine if self-perception of voice changes during CSHT, and if a change of serum testosterone levels as a result of CSHT can predict a change of self-perception of voice. Prospective longitudinal study. The Transsexual Voice Questionnaire (TVQ), consisting of three factors-anxiety and avoidance (AA), gender identity (GI), and voice quality (VQ)-was used. Transgender persons completed the TVQ at baseline (80 trans men and 103 trans women), after 3 and 12 months of CSHT follow-up. Trans men: From 0 to 3 months, 0 to 12 months, and 3 to 2 months of CSHT, the AA and GI scores improved. From 0 to 3 months of CSHT, the increasing testosterone level was predictive for the improvements of AA and GI scores. Trans women: From 0 to 3 months, the GI score improved. From 0 to 12 months, the AA, GI, and VQ scores improved. Improvements of self-perception of voice could not be predicted by changing serum testosterone levels. During CSHT, self-perception of voice improves in both trans men and trans women. In trans men only, the improving self-perception of voice during the first 3 months can be attributed to the CSHT. For trans women, this study supports that testosterone has acted irreversibly virializing to the voice before CSHT, if they already went through male puberty. 4.

2015-06-01

Full Text Available This study explored the relationships between athletes’ competence self-perceptions and metaperceptions. Two hundred and fifty one student-athletes (14.26 ± 1.89 years, members of twenty different teams (basketball, soccer completed a questionnaire which included the Perception of Success Questionnaire, the Competence subscale of the Intrinsic Motivation Inventory, and modified versions of both questionnaires to assess athletes’ metaperceptions. Structural equation modelling analysis revealed that athletes’ task and ego metaperceptions positively predicted task and ego self-perceptions, respectively. Competence metaperceptions were strong predictors of competence selfperceptions, confirming the atypical metaperception formation in outcome-dependent contexts such as sport. Task and ego metaperceptions positively predicted athletes’ competence metaperceptions. How coaches value their athletes’ competence is more influential on what the athletes think of themselves than their own self-perceptions. Athletes’ ego and task metaperceptions influenced their competence metaperceptions (how coaches rate their competence. Therefore, athletes build their competence metaperceptions using all information available from their coaches. Finally, only taskself perfections positively predicted athletes’ competence self-perceptions.

Behaviour change interventions are effective in supporting individuals to achieve clinically significant weight loss, but weight loss maintenance (WLM) is less often attained. This study examined predictive variables associated with WLM. N-of-1 study with daily ecological momentary assessment combined with objective measurement of weight and physical activity, collected with wireless devices (Fitbit™) for six months. Eight previously obese adults who had lost over 5% of their body weight in the past year took part. Data were analysed using time series methods. Predictor variables were based on five theoretical themes: maintenance motives, self-regulation, personal resources, habits, and environmental influences. Dependent variables were: objectively estimated step count and weight, and self-reported WLM plan adherence. For all participants, daily fluctuations in self-reported adherence to their WLM plan were significantly associated with most of the explanatory variables, including maintenance motivation and satisfaction with outcomes, self-regulation, habit, and stable environment. Personal resources were not a consistent predictor of plan adherence. This is the first study to assess theoretical predictions of WLM within individuals. WLM is a dynamic process including the interplay of motivation, self-regulation, habit, resources, and perceptions of environmental context. Individuals maintaining their weight have unique psychological profiles which could be accounted for in interventions.

We tested the moderating role of physical self-perceptions in the relationship between physical maturity and physical self-worth (PSW). Students in Grades 5 through 8 (N = 241; 57% females; Mage = 12.30 years) completed a questionnaire assessing physical self-perceptions (i.e., perceived sport competence, conditioning, strength, and body attractiveness), PSW, and maturity status. Hierarchical multiple regression was used to test interactions between maturity and physical self-perceptions predicting PSW separately for boys and girls. For girls, maturity level and physical self-perceptions explained significant variance, F(5, 131) = 73.44, p < .001, R(2) = .74, with interactions explaining a little extra variance, ΔF = 3.42, p = .01, ΔR(2) = .03. Perceived attractiveness interacted with maturity status to predict PSW (p = .01), indicating that maturity was positively related to PSW only for girls with higher body attractiveness. Maturity status and physical self-perceptions also significantly predicted PSW in boys, F(5, 98) = 46.52, p <  .001, R(2) = .70, with interactions explaining a little extra variance, ΔF = 3.16, p = .02, ΔR(2) = .04. A statistically significant interaction between perceived strength and maturity (p <  .001) indicated that maturity related positively to PSW, but only for boys with higher perceived strength. The maturity-PSW relationship differs by gender and depends partly on physical self-perceptions. This finding reinforces previous findings that illustrate the relative importance of perceived attractiveness and strength for girls and boys, respectively. PSW is an important predictor of physical activity behavior; therefore, it is critical to understand the interplay between these key antecedents.

We report a new procedure for assessing complex self-motion perception. In three experiments, subjects manipulated a 6 degree-of-freedom magnetic-field tracker which controlled the motion of a virtual avatar so that its motion corresponded to the subjects' perceived self-motion. The real-time animation created by this procedure was stored using a virtual video recorder for subsequent analysis. Combined real and illusory self-motion and vestibulo-ocular reflex eye movements were evoked by cross-coupled angular accelerations produced by roll and pitch head movements during passive yaw rotation in a chair. Contrary to previous reports, illusory self-motion did not correspond to expectations based on semicircular canal stimulation. Illusory pitch head-motion directions were as predicted for only 37% of trials; whereas, slow-phase eye movements were in the predicted direction for 98% of the trials. The real-time computer-generated animations procedure permits use of naive, untrained subjects who lack a vocabulary for reporting motion perception and is applicable to basic self-motion perception studies, evaluation of motion simulators, assessment of balance disorders and so on.

Self-testing technology allows people to test themselves for chlamydia without professional support. This may result in reassurance and wider access to chlamydia testing, but anxiety could occur on receipt of positive results. This study aimed to identify factors important in understanding self-testing for chlamydia outside formal screening contexts, to explore the potential impacts of self-testing on individuals, and to identify theoretical constructs to form a Framework for future research and intervention development.

Full Text Available Purpose: Weight misperceptions appear common among youth, potentially influencing their motivation to engage in health-related behaviours; however, the direction of impact remains unclear. The current study examined how weight perception influences physical activity (PA and diet among youth. Methods: This study used 2-year linked data of 19,322 grade 9–12 students from Year 2 (Y2:2013-2014 and 3 (Y3:2014-2015 of the COMPASS study. Generalized Estimating Equation models tested the effect of Y3 weight perception on the various Y3 PA and dietary behaviour measures, adjusting for Y3 covariates (grade, race/ethnicity, weekly spending money, school cluster, school area median household income, and the Y2 outcome. Models were stratified by gender and body mass index (BMI classification. Results: Regardless of BMI status, overweight perceptions among boys and girls were associated with lower likelihoods of playing school sports, physical education class enrollment, meeting resistance exercise recommendations, eating breakfast regularly, and less vigorous-intensity PA, and among boys only, lower odds of meeting PA guidelines, compared to their peers who perceived their weight as “about right”. In boys with normal-weight BMIs, underweight perceptions predicted less vigorous-intensity PA, and lower odds of physical education class enrollment, and of meeting PA and resistance exercise recommendations, than “about right” perceptions. Among girls, underweight perceptions predicted lower likelihoods of engaging in adequate resistance exercise and playing intramurals, and greater odds of eating fast food on weekends, purchasing snacks, and drinking energy drinks and sugar-sweetened beverages. Girls with overweight/obese BMIs who perceived their weight as such were less likely to consume adequate fruits and vegetables relative to their counterparts with “about right” weight perceptions. Conclusions: Overall, weight perceptions of “about right�

Married individuals often have higher body weights than unmarried individuals, but it is unclear how marital roles affect body weight-related perceptions, desires, and behaviors. This study analyzed cross-sectional data for 4,089 adult men and 3,989 adult women using multinomial logistic regression to examine associations between marital status, perceived body weight, desired body weight, and weight management approach. Controlling for demographics and current weight, married or cohabiting women and divorced or separated women more often perceived themselves as overweight and desired to weigh less than women who had never married. Marital status was unrelated to men's weight perception and desired weight change. Marital status was also generally unrelated to weight management approach, except that divorced or separated women were more likely to have intentionally lost weight within the past year compared to never married women. Additionally, never married men were more likely to be attempting to prevent weight gain than married or cohabiting men and widowed men. Overall, married and formerly married women more often perceived themselves as overweight and desired a lower weight. Men's marital status was generally unassociated with weight-related perceptions, desires, and behaviors. Women's but not men's marital roles appear to influence their perceived and desired weight, suggesting that weight management interventions should be sensitive to both marital status and gender differences. © 2013 Elsevier Ltd.

Whether a low body mass index (BMI) is directly associated with a high risk of suicidal ideation or self-harming behavior in adolescents is still inconclusive. This study has, therefore, evaluated the relevance of BMI to suicidal ideation and self-harming behavior after controlling for body weight perception (BWP) and other potential confounding factors. BMI, BWP, suicidal ideation, and self-harming behavior were all assessed using a self-report questionnaire administered to 18,104 Japanese adolescents. Potential confounding factors were also evaluated. The data were then analyzed using bivariate and multivariate logistic regression. Low BMI was associated with suicidal ideation and deliberate self-harm when controlling for sex, age, drug use, emotional distress, and BWP. Low BMI may be an independent risk factor for suicidal ideation and deliberate self-harming behavior in Japanese adolescents.

Full Text Available Introduction. Overweight and perception of being overweight, may lead adolescent to lose weight. The aim of the present study was to investigate overweight adolescents’ self-perceived weight, body dissatisfaction, and weight control behaviour during 1994–2010 in Finland. Methods. The country-representative, cross-sectional data of 15-year olds were obtained from the Health Behaviour in School-aged Children (HBSC study, conducted in 1994 (=1194; males: 48%, 1998 (=1545; 49%, 2002 (=1745; 50%, 2006 (=1670; 47%, and 2010 (=2082; 48%. Results. The majority of overweight boys (62–69% and girls (89–100% assessed themselves as too fat, and their body image was lower than in nonoverweight adolescents. The highest prevalence of current weight controlling was found in 2006 in males (18% and in 2010 in females (39%. Conclusion. The phenomena were current and gender differences notable, but there was no statistically significant difference in overweight adolescents’ self-perceived weight, body dissatisfaction, or weight control behaviour between survey years.

Attenuation of Self-Generated Tactile Sensations is Predictive, not Postdictive.

Directory of Open Access Journals (Sweden)

2006-01-01

Full Text Available When one finger touches the other, the resulting tactile sensation is perceived as weaker than the same stimulus externally imposed. This attenuation of sensation could result from a predictive process that subtracts the expected sensory consequences of the action, or from a postdictive process that alters the perception of sensations that are judged after the event to be self-generated. In this study we observe attenuation even when the fingers unexpectedly fail to make contact, supporting a predictive process. This predictive attenuation of self-generated sensation may have evolved to enhance the perception of sensations with an external cause.

This study was carried out among undergraduate students in Universiti Malaysia Sarawak with the objective of examining gender differences in body mass index (BMI), body weight perception, eating attitudes and weightloss strategies. Subjects consisted of 600 undergraduates (300 males and 300 females) recruited from the various faculties between September 2008 until mid-November 2008. The Original Figure Rating Scale: Body Weight Perception, Body Shape Questionnaire (BSQ) and Eating Attitudes Test-26 (EAT-26) were used as assessment tools. Overall, 52.8% of students had normal BMI, with approximately an equal number of both sexes. More males than females were overweight (33.7%), while more females were underweight (25.3%). Males were more likely to perceive themselves as overweight, and fail to see themselves as underweight. More than half of the females preferred their ideal figure to be underweight, whereas about 30% males chose an overweight figure as their ideal model. Females were generally more concerned about body weight, body shape and eating than males. They diet more frequently, had self-induced vomiting, and used laxatives and exercise as their weight-loss strategies. Issues pertaining to body weight perception, eating attitudes and weight-loss strategies exist with differences among male and female undergraduates. Thus, in order to correct misperceptions among young adults, a more tailored intervention programme and more in-depth studies into the various factors involved are required.

Research suggests that contextual, self-system, and school engagement variables influence dropping out from school. However, it is not clear how different types of contextual and self-system variables interact to affect students’ engagement or contribute to decisions to dropout from high school. The self-system model of motivational development represents a promising theory for understanding this complex phenomenon. The self-system model acknowledges the interactive and iterative roles of social context, self-perceptions, school engagement, and academic achievement as antecedents to the decision to dropout of school. We analyzed data from the Education Longitudinal Study of 2002–2004 in the context of the self-system model, finding that perception of social context (teacher support and parent support) predicts students’ self-perceptions (perception of control and identification with school), which in turn predict students’ academic and behavioral engagement, and academic achievement.

To recommend strategies for enhancing patients' sense of self-worth and self-efficacy in order to give them sufficient faith in themselves to make healthier choices about their weight. PubMed, PsycINFO, Google Scholar, and APA Journals Online were searched for original research articles on treatment models and outcome review articles from 1960 to the present. Key search terms were weight loss, weight-loss treatments, diets and weight loss, psychology and obesity, physiology and obesity, and exercise and weight loss. Most evidence was level I and level II. In spite of extensive research, there is widespread belief that the medical system has failed to stem the tide of weight gain in North America. The focus has been on physiologic, behavioural, and cultural explanations for what is seen as a relatively recent phenomenon, while the self-perception of overweight individuals has been largely overlooked. Professional treatments have consisted mainly of cognitive behavioural therapies and rest on the premise that overweight patients will effectively apply the cognitive behavioural therapy principles. In the long run, professional and commercial programs are often ineffective. We need treatments that include strategies to repair ego damage, enhance the sense of self-worth, and develop self-efficacy so that overweight patients can become the agents of change in their pursuit of well-being. Self-efficacy correlates positively with success in all realms of personal endeavour, and we can help our overweight patients become more self-reliant.

'feeling healthy' as a determinant of maintaining a healthy weight. Despite these beliefs, many teens had unrealistic and unhealthy perceptions of weight. Female participants were more concerned with weight than males, some to the point of obsession. Both males and females expressed a social stigma associated with overweight. Issues of guilt and diminished self-esteem were prevalent. When asked about the extensiveness of the problem of childhood overweight, the students indicated that a degree of familiarity with being overweight has developed and 'you just get used to [seeing] it.' Because of the rising rates of chronic disease in this region, a fear was evident in these youth about the increased risk of developing these conditions in those who are overweight. Experiences with family members with diabetes and cardiovascular disease fueled these concerns, which instilled a fear of becoming overweight in many of the students. Many perceptions of healthy weight and appropriate body size were shaped by the media and entertainment industry. Additionally, some participants admitted to performing unsafe practices to reduce body mass, such as very low calorie diets or fasting. Youth in rural Appalachia present similar perceptions about weight as other children; however, differences in perceived healthy lifestyle habits and a general acceptance of a higher average body weight present additional challenges to addressing the increasing problem of child overweight. Despite the relative isolation of many of these communities, the media has a profound impact on weight valuation that has been intertwined with school-based health education and cultural values of health. These data will provide valuable information for the development of obesity prevention programs in rural Appalachia.

Research has demonstrated that, despite difficulties in multiple domains, children with autism spectrum disorders (ASD) show a lack of awareness of these difficulties. A misunderstanding of poor competencies may make it difficult for individuals to adjust their behaviour in accordance with feedback and may lead to greater impairments over time. This study examined self-perceptions of adolescents with ASD (n = 19) and typically developing (TD) mental-age-matched controls (n = 22) using actual performance on objective academic tasks as the basis for ratings. Before completing the tasks, participants were asked how well they thought they would do (pre-task prediction). After completing each task, they were asked how well they thought they did (immediate post-performance) and how well they would do in the future (hypothetical future post-performance). Adolescents with ASD had more positively biased self-perceptions of competence than TD controls. The ASD group tended to overestimate their performance on all ratings of self-perceptions (pre-task prediction, immediate, and hypothetical future post-performance). In contrast, while the TD group was quite accurate at estimating their performance immediately before and after performing the task, they showed some tendency to overestimate their future performance. Future investigation is needed to systematically examine possible mechanisms that may be contributing to these biased self-perceptions. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

Self-perception, self-regulation and metacognition in adolescents with intellectual disability.

Nader-Grosbois, Nathalie

2014-06-01

This study compares self-perception of competences in 28 typically developing children (TD) aged 7-9 years and 32 adolescents with intellectual disability (ID) aged 11-16 years in special school, matched for mental age (MA). The links between self-perception, self-regulation in problem-solving and metacognition are investigated. Overall self-perception and self-perception of competences by domain do not differ significantly between the two groups. Self-perception of competences in specific domains, self-regulation and metacognition vary depending on MA and verbal comprehension in the two groups. ID adolescents attribute more importance to social acceptance than TD children. In both groups, positive links are identified between self-perception and importance attributed to domains. Performance, self-regulation and metacognition are lower in ID adolescents than in TD children. Positive links are obtained between self-perception of competences in specific domains and certain self-regulatory and metacognitive strategies, although these links differ in the two groups.

During self-motion, humans typically move the eyes to maintain fixation on the stationary environment around them. These eye movements could in principle be used to estimate self-motion, but their impact on perception is unknown. We had participants judge self-motion during different eye-movement conditions in the absence of full-field optic flow. In a two-alternative forced choice task, participants indicated whether the second of two successive passive lateral whole-body translations was longer or shorter than the first. This task was used in two experiments. In the first ( n = 8), eye movements were constrained differently in the two translation intervals by presenting either a world-fixed or body-fixed fixation point or no fixation point at all (allowing free gaze). Results show that perceived translations were shorter with a body-fixed than a world-fixed fixation point. A linear model indicated that eye-movement signals received a weight of ∼25% for the self-motion percept. This model was independently validated in the trials without a fixation point (free gaze). In the second experiment ( n = 10), gaze was free during both translation intervals. Results show that the translation with the larger eye-movement excursion was judged more often to be larger than chance, based on an oculomotor choice probability analysis. We conclude that eye-movement signals influence self-motion perception, even in the absence of visual stimulation.

Full Text Available Aim: In Korea, obesity is more prevalent among men and lower socioeconomic groups. To explain this obesity disparity, we compared weight perception and weight control behavior across gender and socioeconomic status (SES. Methods: We analyzed data from 16,260 participants aged 20 years or older in a nationally representative cross-sectional survey. SES indicators included education and income levels. Weight under-perception was defined when participants considered themselves lighter than their measured BMI status. Either no active or inappropriate weight control (i.e., trying to gain weight in obese individuals was considered to be unhealthy patterns. Multivariate prevalence ratios were calculated using log-binomial regressions. Results: Men had a higher prevalence of weight under-perception (24.5 vs. 11.9% and unhealthy patterns of weight control behavior (57 vs. 40% than women. Low education level was associated with weight under-perception (ptrend = 0.022 in men, ptrend trend trend = 0.047 in men, ptrend Conclusion: Weight perception and weight control behavior significantly varied by gender and SES. Public actions should be directed toward improving perception and behavior of high-risk populations.

Obesity, in the past was perceived to be the problem of the rich, but recent studies have reported that the problem of obesity is a worldwide problem and rural population is no less affected. Self-perceived health and weight appropriateness is an important component of weight-loss and eating behaviors and may be mediated by local, social and cultural patterning. In addition to the quality of life assessment, it should therefore be an important focal point for the design and implementation of clinical and public health policies. The present study was carried out to assess the self-perception of weight appropriateness as well as the quality of life of overweight and obese individual among the rural population particularly among housewives. A total of 421 respondents participated in the study which consisted of 36.6% in the overweight and 63.4% in the obese categories. the analysis of the survey revealed that self-perception regarding obesity among respondents show common similarities, particularly in self reporting on health, dietary habit and also the concept of beauty and a beautiful body. Character and behavior are highly regarded in evaluating a person's self-worth in society. The results on the quality of life using the ORWELL 97 instrument show that the quality of life of respondents was moderate. Most of the respondents were aware of their body weight and indicated an intention to lose weight but also reported themselves as healthy or very healthy. The results of the survey indicated that perception on obesity did not differed very much between respondents, in fact there existed a lot of similarities in their perception about health, quality of life, personal health and self-satisfaction with own body. However, their quality of life was within the normal or moderate level based on the ORWELL 97 assessment. Even though most of the respondents were aware of their body weight and indicated an intention to lose weight they also reported themselves as healthy or

Previous studies have tested multivariate models of bulimia pathology development, documenting that a confluence of perfectionism, body dissatisfaction, and low self-esteem is predictive of disordered eating. However, attempts to replicate these results have yielded controversial findings. The objective of the present study was to test an interactive model of perfectionism, weight and shape concerns, and self-esteem in a sample of patients affected by Eating Disorder (ED). One-hundred-sixty-seven ED patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), and they completed the Eating Disorder Examination Questionnaire (EDE-Q), the Rosenberg Self-Esteem Scale (RSES), and the Multidimensional Perfectionism Scale (MPS-F). Several mediation analysis models were fit to test whether causal effects of concern over weight and shape on the frequency of bulimic episodes were mediated by perfectionism and moderated by low levels of self-esteem. Contrary to our hypotheses, we found no evidence that the causal relationship investigated was mediated by any of the dimensions of perfectionism. As a secondary finding, the dimensions of perfectionism, perceived criticism and parental expectations, were significantly correlated with the presence of bulimic symptoms. The validity of the interactive model remains controversial, and may be limited by an inadequate conceptualization of the perfectionism construct.

The purpose of this study was to study the associations between specific self-perceptions and global self-worth with different frequency levels of sport participation among Spanish boys and girls adolescents. Students (457 boys and 460 girls) completed the Self Perception Profile for Children (Harter, 1985) and items assessing sport engagement from The Health Behavior in School Children Questionnaire (Wold, 1995). Results showed that some specific dimensions of self-perception were related to different frequency of sport participation whereas overall judgments of self-worth did not. Specifically, for boys and girls, higher levels of sport participation were positively associated to Athletic Competence, and for boys were also associated with Physical Appearance and Social Acceptance. The potential implications of domain specific socialisation processes on the configuration of self-perceptions are highlighted.

There have been few studies in the area of Self-Perception in transsexual persons, except for the population of transsexual adolescents. Bearing in mind its importance not only in the assessment of personality but also in predicting adaptive capacity, the goal of our research is based on the examination of Self-Perception of adult transsexual persons. The study was conducted using a Rorschach test, which provides an insight into various aspects of Self-Perception. The sample consisted of 15 transsexual persons, who passed the standard diagnostic procedure. The results suggest that transsexual persons manage to maintain Adequate Self-Esteem. Hypervigilance Index and Obsessive Style Index are negative, while the values showing a negative quality of Self-Regard and the capacity for introspection tend to increase. In the process of Self-Introspection, negative and painful emotional states are often perceived. The estimation of Self-Perception in adult transsexual persons indicates a trend of subjective perception of a personal imperfection or inadequacy. This is probably the result of experiencing discomfort for a number of years due to gender incongruence and dysphoria, in particular in persons who enter the sex reassignment procedure later in their adulthood.

Parents influence their child's eating behavior and attitudes directly as food providers and indirectly through their parental feeding styles and feeding concerns and practices. Chinese American parents' practices are likely influenced by culture. The objective of this study was to explore the relationships between parental perceptions, feeding practices, feeding styles, level of parental acculturation (LPA), and child weight status via a self-administered questionnaire. This survey study involved a convenience sample of 712 individuals who were parents of 5- to 10-year old children attending Chinese language after-school programs. The prevalence of overweight was 11.5% and obesity was 11.1%. LPA was not directly predictive of child overweight in multiple regression but from categorical data, Chinese American parents tended to use indulgent (33.2%) and authoritarian (27.9%) feeding styles, with the former increasing with acculturation and the latter decreasing. Indulgent parents had more than expected overweight and obese children, and authoritarian and authoritative parents, fewer. LPA was negatively predictive of pressure to eat healthy foods (p Parental perceptions and concerns about child weight were predictors of child weight. Consequently, parental concerns and responsiveness to child needs without also encouragement (demandingness) to eat healthy foods (indulgent feeding style) may promote overweight. The authoritative parental feeding style may contribute to children having healthy weights and therefore healthy lives. Copyright © 2014 Elsevier Ltd. All rights reserved.

Predicting short-term weight loss using four leading health behavior change theories

2007-04-01

Full Text Available Abstract Background This study was conceived to analyze how exercise and weight management psychosocial variables, derived from several health behavior change theories, predict weight change in a short-term intervention. The theories under analysis were the Social Cognitive Theory, the Transtheoretical Model, the Theory of Planned Behavior, and Self-Determination Theory. Methods Subjects were 142 overweight and obese women (BMI = 30.2 ± 3.7 kg/m2; age = 38.3 ± 5.8y, participating in a 16-week University-based weight control program. Body weight and a comprehensive psychometric battery were assessed at baseline and at program's end. Results Weight decreased significantly (-3.6 ± 3.4%, p Conclusion The present models were able to predict 20–30% of variance in short-term weight loss and changes in weight management self-efficacy accounted for a large share of the predictive power. As expected from previous studies, exercise variables were only moderately associated with short-term outcomes; they are expected to play a larger explanatory role in longer-term results.

Full Text Available Objective: To report the self-perception of substance-abusing individuals who were in a recovery process regarding sociodemographic conditions and general and oral health. Methods: Descriptive cross-sectional study conducted in a recovery center for drug addiction in Alfenas, Minas Gerais, Brazil, in 2015, with 39 men aged over 18 years old. Data were collected using a semi-structured questionnaire that addressed: socioeconomic status, selfperception of general and oral health, access to dental care, relationship with the dentist, and other issues. In order to assess the self-perception of oral health, the variable was dichotomized into “satisfactory” and “unsatisfactory”, which refer to what the individual acknowledges as a good or poor condition of oral health, using Fisher’s exact test with 5% significance level. Results: Most frequent diseases were depression, 35.90% (n=14, insomnia, 35.9%, (n=14 and recurring headache (23.1%; n=9; however, 61.50% (n=24 of the participants reported not getting sick easily, which contrasts with their self-perception. Regarding oral health, only 30.50% (n=12 of the participants reported brushing their teeth three times a day; 53.80% (n=21 had dentinal hypersensitivity; 41.00% (n=16 had dry mouth and bad breath; 30.80% (n=12 claimed to have bruxism and reported having one or more loose teeth; 28.20% (n=11 reported clenching the teeth in an exaggerated way, and 33.30% (n=13 reported feeling tooth pain. Conclusion: The self-perception of individuals – under 30 years old, single, white or mulattos – regarding their general health was contradictory, as they rated it as good but have reported depression, insomnia and weight loss; additionally, oral health was considered poor with unsatisfactory conditions, which highlights the harmful effects of substance abuse.

Pre-treatment diet and exercise self-efficacies can predict weight loss success. Changes in diet self-efficacy across treatment appear to be even stronger predictors than baseline levels, but research on changes in exercise self-efficacy is lacking. Using data from a pilot study evaluating tangible reinforcement for weight loss (N=30), we examined the impact of changes in diet and exercise self-efficacy on outcomes. Multiple regression analyses indicated that treatment attendance and changes in exercise self-efficacy during treatment were the strongest predictors of weight loss. Developing weight loss programs that foster the development of exercise self-efficacy may enhance participants' success. Published by Elsevier Ltd.

To determine whether increases in adolescent or parental self-efficacy predicted subsequent weight gain in two different therapies for adolescent anorexia nervosa (AN). Participants were 121 adolescents with AN (M = 14.4 years, SD = 1.6), from a two-site randomized clinical trial for family-based treatment (FBT) and individual adolescent focused therapy (AFT). Both adolescent and parental self-efficacy were assessed at baseline and sessions 2, 4, 6, and 8. Adolescent self-efficacy was assessed using a generic measure of self-efficacy, while parental self-efficacy was assessed using a measure specific to the recovery of an eating disorder. Weight was assessed at baseline, sessions 1 through 8, and end of treatment. Mixed-effects models were used to evaluate the relation between patient and parent self-efficacy and subsequent weight gain, controlling for weight at the previous time point. For families who received FBT, greater within-treatment increases in parental self-efficacy predicted greater subsequent adolescent weight gain compared to those who received FBT with lesser change in parental self-efficacy and those who received AFT. Interestingly, adolescent self-efficacy did not significantly predict subsequent weight gain. Greater increases in parental self-efficacy predicted significantly greater subsequent weight gain for adolescents who received FBT, but the same was not true for adolescents who received AFT. Neither overall level nor change in adolescent self-efficacy significantly predicted subsequent weight gain in either treatment group. These findings emphasize the importance of increasing parental self-efficacy in FBT in order to impact adolescent weight outcomes. © 2015 Wiley Periodicals, Inc.

For decades, behavioral weight-loss treatments have been unsuccessful beyond the short term. Development and testing of innovative, theoretically based methods that depart from current failed practices is a priority for behavioral medicine. To evaluate a new, theory-based protocol in which exercise support methods are employed to facilitate improvements in psychosocial predictors of controlled eating and sustained weight loss. Women with obesity were randomized into either a comparison treatment that incorporated a print manual plus telephone follow-ups (n = 55) or an experimental treatment of The Coach Approach exercise-support protocol followed after 2 months by group nutrition sessions focused on generalizing self-regulatory skills from an exercise support to a controlled eating context (n = 55). Repeated-measures analysis of variance contrasted group changes in weight, physical activity, fruit and vegetable intake, mood, and exercise- and eating-related self-regulation and self-efficacy over 24 months. Regression analyses determined salient interrelations of change scores over both the weight-loss phase (baseline-month 6) and weight-loss maintenance phase (month 6-month 24). Improvements in all psychological measures, physical activity, and fruit and vegetable intake were significantly greater in the experimental group where a mean weight loss of 5.7 kg (6.1% of initial body weight) occurred at month 6, and was largely maintained at a loss of 5.1 kg (5.4%) through the full 24 months of the study. After establishing temporal intervals for changes in self-regulation, self-efficacy, and mood that best predicted improvements in physical activity and eating, a consolidated multiple mediation model suggested that change in self-regulation best predicted weight loss, whereas change in self-efficacy best predicted maintenance of lost weight. Because for most participants loss of weight remained greater than that required for health benefits, and costs for treatment

Relationships among adolescents' weight perceptions, exercise goals, exercise motivation, quality of life and leisure-time exercise behaviour: a self-determination theory approach.

2006-12-01

Exercise has an important role to play in the prevention of child and adolescent obesity. Recent school-based interventions have struggled to achieve meaningful and lasting changes to exercise levels. Theorists have suggested that this may, in part, be due to the failure to incorporate psychosocial mediators as they relate to behaviour change. Using a sample of 580 British schoolchildren, a model grounded in self-determination theory was explored to examine the effects of exercise goals on exercise motivation, leisure-time exercise behaviour and quality of life (QoL). Results of structural equation modelling revealed that adolescents perceiving themselves to be overweight and pressurized to lose weight, endorsed extrinsic weight-related goals for exercise. Extrinsic goals negatively predicted, whereas intrinsic goals positively predicted, self-determined motivation, which in turn positively predicted QoL and exercise behaviour. Furthermore, self-determined motivation partially mediated the effects of exercise goals on reported exercise behaviour and QoL. Multi-sample invariance testing revealed the proposed model to be largely invariant across gender. Results suggest that holding extrinsic exercise goals could compromise exercise participation levels and QoL. A role for teachers and parents is proposed with the aim of orienting young people towards intrinsic goals in an attempt to enhance future exercise behaviour and QoL.

Young adults are underrepresented in standard behavioral weight loss trials, and evidence suggests that they differ from older adults on many weight-related constructs. The aim of this review is to explore young adults' attitudes toward obesity and weight management, with particular attention to those factors that may play a role in the development of future treatment efforts. Both intrapersonal and interpersonal considerations unique to young adulthood are assessed; in addition, we examine young adults' perceptions of specific weight-related behaviors such as dieting, physical activity, and self-weighing. Conclusions are consistent with other findings suggesting that weight management interventions should be adapted and designed specifically for this age group.

To report a correlational study of the relation of body mass index to children's perceptions of physical appearance and global self-worth and depression, as mediated by their perceptions of parental teasing. The relation between depression and self-perception in children with obesity has been reported. Recently, parental factors were found to be related to childhood obesity. Little is known about the effects of perceived parental teasing on depression and self-perception in children. A descriptive correlational research design was used. Data were collected from 455 children in the fifth and sixth grades in four provinces of South Korea using self-report questionnaires for measuring self-perception of physical appearance and global self-worth, depression and perceived parental teasing between October-December in 2009. The children's weight and height information from school health records was used. Multiple regression analysis and the Sobel test were used to identify the mediating effect of perceived parental teasing. Among the children, 20% were overweight or obese. Although children with obesity did not differ in the level of depression from their normal weight counterparts, they demonstrated lower perceived physical appearance and higher perceived parental teasing. The mediating effects of perceived parental teasing were found for the relations between body mass index and self-perception of physical appearance and global self-worth, and body mass index and depression, respectively. Obese children at risk of parental teasing should be identified to prevent their psychological problems. A well-designed intervention study is necessary to examine the effects of psycho-emotional interventions for obese children. © 2012 Blackwell Publishing Ltd.

Although psychological theories outline that it might be beneficial to set more challenging goals, people attempting to lose weight are generally recommended to set modest weight loss goals. The present study explores whether the amount of weight loss individuals strive for is associated with more positive psychological and behavioral outcomes. Hereto, 447 overweight and obese participants trying to lose weight completed two questionnaires with a 2-month interval. Many participants set goals that could be considered unrealistically high. However, higher weight loss goals did not predict dissatisfaction but predicted more effort in the weight loss attempt, as well as more self-reported short-term weight loss when baseline commitment and motivation were controlled for.

Conflicting results have emerged regarding the prognostic significance of weight suppression for maintenance of bulimic symptoms. This study examined whether the magnitude of weight suppression would predict bulimic syndrome maintenance and onset in college-based samples of men (n=369) and women (n=968) at 10-year follow-up. Data come from a longitudinal study of body weight and disordered eating with high retention (80%). Among those with a bulimic syndrome at baseline, greater weight suppression significantly predicted maintenance of the syndrome, and, among those without a bulimic syndrome at baseline, greater weight suppression predicted onset of a bulimic syndrome at 10-year follow-up in multivariate models that included baseline body mass index, diet frequency, and weight perception. Future research should address mechanisms that could account for the effects of weight suppression over a long duration of follow-up. PMID:20455599

This study investigated: (1) the prevalence and development of 2 receptive (sexually explicit Internet material [SEIM] use and sexual information seeking) and 2 interactive (cybersex and general social networking site [SNS] use) online behaviors in adolescence; (2) whether development of these behaviors predict adolescents' body and sexual self-perceptions; and (3) whether parental strategies regarding adolescents' Internet use reduce engagement in sex-related online behaviors. Four-wave longitudinal data among 1132 seventh- to 10th-grade Dutch adolescents (mean age at wave 1: 13.95 years; 52.7% boys) were collected. Developmental trajectories of sex-related online behaviors were estimated by using latent growth curve modeling. Self-perception outcomes at wave 4 and parental strategies predicting online behaviors were investigated by adding regression paths to growth models. Boys occasionally and increasingly used SEIM. Patterns for girls' SEIM use and boys' and girls' sexual information seeking and cybersex were consistently low. SNS use, however, was a common, daily activity for both. Higher initial levels and/or faster increases in sex-related online behaviors generally predicted less physical self-esteem (girls' SNS use only), more body surveillance, and less satisfaction with sexual experience. Private Internet access and less parental rule setting regarding Internet use predicted greater engagement in sex-related online behaviors. Although most sex-related online behaviors are not widespread among youth, adolescents who engage in such behaviors are at increased risk for developing negative body and sexual self-perceptions. Particular attention should be paid to adolescents' SNS use because this behavior is most popular and may, through its interactive characteristics, elicit more critical self-evaluations. Prevention efforts should focus on parents' role in reducing risky sex-related online behaviors. Copyright © 2014 by the American Academy of Pediatrics.

Disordered weight management behaviors are prevalent among youth; recent case reports suggested that these behaviors might also be common in transgender youth. We studied associations of gender identity with disordered weight management behaviors, nonprescription steroid use, and weight perception among transgender and cisgender (nontransgender) high-school students in Massachusetts. Data were analyzed from the 2013 Massachusetts Youth Health Survey, an anonymous survey in a random sample of Massachusetts public high schools. Respondents were divided into three groups: transgender (n = 67), cisgender male (n = 1,117), and cisgender female (n = 1,289). Fisher's exact tests and multivariable logistic regression models were used to examine unhealthy weight management behaviors in the past 30 days: fasting >24 hours, vomiting, diet pill use, and laxative use; nonprescription steroid use; and self-perceived weight status. Analyses controlled for age, race/ethnicity, and body mass index. Compared with cisgender males, transgender adolescents had higher odds of fasting >24 hours (adjusted odds ratio [AOR] = 2.9, confidence interval [CI] = 1.1-7.8), using diet pills (AOR = 8.9, 95% CI = 2.3-35.2) and taking laxatives (AOR = 7.2, 95% CI = 1.4-38.4). Transgender youth had higher odds of lifetime use of steroids without a prescription than male cisgender respondents (AOR = 26.6, 95% CI = 3.5-200.1). Compared with cisgender females, transgender respondents had higher odds of perceiving themselves as healthy weight/underweight when they were overweight/obese (AOR = 2.4, 95% CI = 1.5-4.1). Transgender youth disproportionately self-reported unsafe weight management behaviors and nonprescription steroid use compared with cisgender youth. Clinicians should be aware of this increased risk among transgender youth. Research is needed to further understand these disparities and to inform future interventions.

Physical activity (PA) seems to be important for long-term weight loss after bariatric surgery; however, studies provide evidence for insufficient PA levels in bariatric patients. Research found self-efficacy to be associated with PA and weight bias internalization, for which an influence on mental and physical health has been shown in recent studies. The purpose of the present study was to investigate the influence of general self-efficacy on PA, mediated by weight bias internalization. In 179 bariatric surgery candidates, general self-efficacy, weight bias internalization, and different intensities of PA were assessed by self-report questionnaires. Structural equation modeling was used to analyze the assumed mediational relationship. After controlling for sociodemographic variables, weight bias internalization fully mediated the association between general self-efficacy and moderate-intense as well as vigorous-intense PA. Lower general self-efficacy predicted greater weight bias internalization, which in turn predicted lower levels of moderate-intense and vigorous-intense PA. The results suggest an influence of weight bias internalization on preoperative PA in bariatric surgery candidates. Subsequently, implementation of interventions addressing weight bias internalization in the usual treatment of bariatric surgery candidates might enhance patients' preoperative PA, while longitudinal analyses are needed to further examine its predictive value on PA after bariatric surgery.

Full Text Available OBJETIVO: Comparar a autopercepção corporal e o estado nutricional objetivamente medido por meio de peso, altura e pregas cutâneas em adolescentes e avaliar os fatores associados à discordância entre essas duas medidas. MÉTODOS: A amostra incluiu os membros da coorte de nascimentos de 1993 na Cidade de Pelotas, Estado do Rio Grande do Sul, Brasil, que foram visitados em seus domicílios em 2004 e 2005. O desfecho em estudo resultou da comparação entre o estado nutricional e a percepção que os adolescentes tinham de seu peso corporal, sendo dividido em três categorias: subestimação, concordância e superestimação. As variáveis explanatórias foram sexo, cor da pele, índice de bens, sedentarismo, dieta inadequada, discriminação, regime para emagrecimento e sentimento de bem-estar e opinião do adolescente sobre como os pais percebiam o corpo desse adolescente. Para as análises estatísticas, empregou-se regressão logística multinomial. RESULTADOS: Foram entrevistados 4 452 indivíduos (87,5% da coorte original. A média de idade foi de 11 anos. De acordo com o estado nutricional, 7,1% foram classificados como magros, 69,8% como eutróficos, 11,6% com sobrepeso e 11,6% com obesidade. Com relação ao peso percebido, 19% dos jovens se achavam magros ou muito magros, 56% se sentiam normais quanto ao peso e 25% se consideravam gordos ou muito gordos. A concordância global entre a autopercepção corporal do adolescente e seu estado nutricional foi de 65% (kappa = 0,36. A subestimação foi de 24,9% entre meninos vs. 20,3% entre meninas. A superestimação foi de 15,8 % entre meninas vs. 8,5% entre meninos. CONCLUSÃO: Houve tendência de as meninas superestimarem o seu peso corporal e de os meninos subestimarem o mesmo. Detectou-se também forte associação entre a opinião que os adolescentes acreditam que os pais têm de si e a autopercepção de estado nutricional dos adolescentes.OBJECTIVE: To compare weight self-perception

Coatsworth, J Douglas; Conroy, David E

2009-03-01

This study tested a sequential process model linking youth sport coaching climates (perceived coach behaviors and perceived need satisfaction) to youth self-perceptions (perceived competence and global self-esteem) and youth development outcomes (initiative, identity reflection, identity exploration). A sample of 119 youth between the ages of 10 and 18 who participated in a community-directed summer swim league completed questionnaires over the course of the 7-week season. Results indicated that coaches' autonomy support, particularly via process-focused praise, predicted youth competence need satisfaction and relatedness need satisfaction in the coaching relationship. Youth competence need satisfaction predicted self-esteem indirectly via perceived competence. Finally, self-esteem predicted identity reflection, and perceived competence predicted both identity reflection and initiative. Effects of age, sex, and perceptions of direct contact with the coach were not significant. Findings suggest that the quality of the coaching climate is an important predictor of the developmental benefits of sport participation and that one pathway by which the coaching climate has its effect on initiative and identity reflection is through developing youth self-perceptions.

Long-term self-monitoring of weight is beneficial for weight maintenance, especially after weight loss. Connected weight scales accumulate time series information over long term and hence enable time series analysis of the data. The analysis can reveal individual patterns, provide more sensitive detection of significant weight trends, and enable more accurate and timely prediction of weight outcomes. However, long term self-weighing data has several challenges which complicate the analysis. Especially, irregular sampling, missing data, and existence of periodic (e.g. diurnal and weekly) patterns are common. In this study, we apply time series modeling approach on daily weight time series from two individuals and describe information that can be extracted from this kind of data. We study the properties of weight time series data, missing data and its link to individuals behavior, periodic patterns and weight series segmentation. Being able to understand behavior through weight data and give relevant feedback is desired to lead to positive intervention on health behaviors.

The aim of this study was to determine self-perception of oral-health in institutionalized elderly, and look into the sociodemographic and clinical aspects associated with negative self-perception. One hundred and sixty-six elderly were assessed by answering a self-perception question that predicts the GOHAI (Geriatric Oral Health Assessment Index). Sociodemographic data was obtained from a previously validated questionnaire and clinical data taken from the WHO file and QST-TMD used to check the existence of TMD (temporomandibular disturbance). The data gathered was submitted to Mann-Whitney, Fisher's Exact and Chi-squared tests with a 5% significance level. The average age of the study population was 80.5, and 75.9% were women. The mean DMFT (decayed, missing, and filled teeth in permanent teeth) was 28.9, the majority of the sample subject (65%) reported good to excellent teeth, gums and prostheses (dentures and bridges). Three questions in the TMD questionnaire (QST-DTM) were associated with negative self-perception. Those claiming that their jaws "lock" when they open or close their mouth, who always have pain at the front or side of their jaw, or whose jaws get tired during the course of the day are less satisfied with their oral health. We conclude that clinical and sociodemographic conditions have little influence on self-perception of oral health, possibly because pain is the main factor associated with negative self-perception in these individuals.

Stigma associated with being overweight or obese is widespread. Given that weight loss is difficult to achieve and maintain, researchers have been calling for interventions that reduce the impact of weight stigma on life functioning. Sound measures that are sensitive to change are needed to help guide and inform intervention studies. This study presents the weight self-stigma questionnaire (WSSQ). The WSSQ has 12 items and is designed for use only with populations of overweight or obese persons. Two samples of participants--one treatment seeking, one nontreatment seeking--were used for validation (N = 169). Results indicate that the WSSQ has good reliability and validity, and contains two distinct subscales-self-devaluation and fear of enacted stigma. The WSSQ could be useful for identifying individuals who may benefit from a stigma reduction intervention and may also help evaluate programs designed to reduce stigma.

Presnell, Katherine; Pells, Jennifer; Stout, Anna; Musante, Gerard

2008-04-01

The aim of the current study was to examine whether weight loss self-efficacy, binge eating, and depressive symptoms predicted weight loss during treatment, and whether gender moderates these associations with prospective data from 297 participants (223 women and 74 men) enrolled in a residential obesity treatment program. Men reported higher initial levels of self-efficacy than women, whereas women reported greater pre-treatment levels of binge eating and depressive symptoms. Higher pre-treatment levels of weight control self-efficacy, binge eating, and depressive symptoms predicted greater weight loss in men, but not in women. Results suggest that certain psychological and behavioral factors should be considered when implementing weight loss interventions, and indicate a need to consider gender differences in predictors of weight loss treatment. Future research should seek to identify predictors of weight loss among women.

Lack of success with behavioral weight-management treatments indicates a need for a better understanding of modifiable psychological correlates. Adults with class 2 and 3 obesity (N = 183; Mean(BMI) = 42.0 kg/m(2)) volunteered for a 26-week nutrition and exercise treatment, based on social cognitive theory, that focused on self-efficacy and self-regulation applied to increasing cardiovascular exercise and fruit and vegetable consumption. Improved self-efficacy for controlled eating significantly predicted increased fruit and vegetable consumption (R(2) = .15). Improved self-efficacy for exercise significantly predicted increased exercise (R(2) = .46). When changes in self-regulatory skill usage were stepped into the 2 previous equations, the variances accounted for significantly increased. Increases in fruit and vegetable consumption and exercise significantly predicted weight loss (R(2) = .38). Findings suggest that behavioral theory should guide research on weight-loss treatment, and a focus on self-efficacy and self-regulatory skills applied to specific nutrition and exercise behaviors is warranted.

People's self-perception biases often lead them to see themselves as better than the average person (a phenomenon known as self-enhancement). This bias varies across cultures, and variations are typically explained using cultural variables, such as individualism versus collectivism. We propose that socioeconomic differences among societies--specifically, relative levels of economic inequality--play an important but unrecognized role in how people evaluate themselves. Evidence for self-enhancement was found in 15 diverse nations, but the magnitude of the bias varied. Greater self-enhancement was found in societies with more income inequality, and income inequality predicted cross-cultural differences in self-enhancement better than did individualism/collectivism. These results indicate that macrosocial differences in the distribution of economic goods are linked to microsocial processes of perceiving the self.

Although obesity continues to rise and remains a great public health concern in the U.S., a number of important levers such as self-perception of weight and calorie postings at point-of-purchase in restaurants are still not well-characterized in the literature, especially for low-income and minority groups in Los Angeles County (LAC). To study this gap, we examined the associations of self-perception of weight (as measured by body weight discrepancy) with food choice intentions and consumer response to calorie information among low-income adults residing in LAC during the pre-menu labeling regulation era. Descriptive and multivariable logistic regression analyses were performed to examine the aforementioned associations utilizing data from the 2007-2008 Calorie and Nutrition Information Survey (CNIS). The CNIS was a local health department study of 639 low-income adults recruited from five large, multi-purpose public health centers in LAC. Survey participants who reported that their desired weight was less than their current weight (versus desired weight the same as current weight) had (i) higher odds of intending to select lower-calorie foods under the scenario that calorie information was available at point-of-purchase (aOR = 2.0; 95 % CI: 1.0-3.9); and (ii) had higher odds of reporting that it is "very important" to have these calorie postings on food items in grocery stores (aOR = 3.1; 95 % CI: 0.90-10.7) and in fast-food restaurants (aOR = 3.4; 95 % CI: 1.0-11.4). Self-perception of weight was found to be associated with the intention to select lower-calorie foods under the scenario that calorie information was available at point-of-purchase. Future public health efforts to support menu labeling implementation should consider these and other findings to inform consumer education and communications strategies that can be tailored to assist restaurant patrons with this forthcoming federal law.

Recent studies have demonstrated neural overlap between resting state activity and self-referential processing. This "rest-self" overlap occurs especially in anterior cortical midline structures like the perigenual anterior cingulate cortex (PACC). However, the exact neurotemporal and biochemical mechanisms remain to be identified. Therefore, we conducted a combined electroencephalography (EEG)-magnetic resonance spectroscopy (MRS) study. EEG focused on pre-stimulus (e.g., prior to stimulus presentation or perception) power changes to assess the degree to which those changes can predict subjects' perception (and judgment) of subsequent stimuli as high or low self-related. MRS measured resting state concentration of glutamate, focusing on PACC. High pre-stimulus (e.g., prior to stimulus presentation or perception) alpha power significantly correlated with both perception of stimuli judged to be highly self-related and with resting state glutamate concentrations in the PACC. In sum, our results show (i) pre-stimulus (e.g., prior to stimulus presentation or perception) alpha power and resting state glutamate concentration to mediate rest-self overlap that (ii) dispose or incline subjects to assign high degrees of self-relatedness to perceptual stimuli.

Youth engage in a variety of methods to manage their weight, including unhealthy weight control behaviors (UWCBs). The purpose of this study was to examine factors associated with youth's engagement in UWCBs, including media influence, youth's BMI z-score and self-esteem. Participants were 179 youth, aged 10-17, attending a primary care clinic appointment. Youth completed questionnaires assessing frequency of UWCBs, global self-worth, and perception of media influence to lose weight. BMI z-score was calculated based on height and weight measurements obtained from medical charts. The SPSS macro, PROCESS, was used to conduct moderation analyses. Over 40% of youth endorsed using at least one UWCB in the past year. Girls reported using more UWCBs and engaging in UWCBs more frequently than boys. For boys, media influence to lose weight was only related to UWCB frequency for those with a BMI z-score of 1.23 and above. For girls, media influence was only related to UWCB frequency for those with low to average levels of global self-worth. Girls' and boys' use of UWCBs is impacted by different factors. Prevention efforts should consider targeting factors, such as weight status and self-esteem, which are uniquely associated with gender. Copyright © 2015. Published by Elsevier Ltd.

To study the effects of age, sex, weight, and their interactions on global self-esteem (GSE) and physical self-concept in teenagers with intellectual disability (ID). A sample of 353 teenagers with ID, aged 12 to 18 years, participated in this study. The Very Short Form of the Physical Self-Inventory—for adolescents with ID (PSI-VSF-ID) was used to assess GSE and physical self-perceptions (physical value perceived [PVP], sport skills [SS], physical condition, physical appearance, and strength). Multivariate covariance analyses show: (i) lower GSE and physical self levels (except for PVP) in females, compared with males; (ii) reduced GSE, PVP, SS, and perceived physical appearance (PPA) scores during adolescence; (iii) lower GSE, PVP, and PPA scores in obese adolescents, compared with overweight or normal weight peers; and (iv) lower PPA scores in obese females, compared with other teenagers. The sex and age results are almost identical to those for the general population, according to the literature. However, they are far from the main effect in the weight category.

We examined the association of body mass index (BMI), body weight perception, and weight control behaviors with problematic Internet use in a nationwide sample of Korean adolescents. Cross-sectional data from the 2010 Korean Youth Risk Behavior Web-based Survey collected from 37,041 boys and 33,655 girls in middle- and high- schools (grades 7-12) were analyzed. Participants were classified into groups based on BMI (underweight, normal weight, overweight, and obese), body weight perception (underweight, normal weight, and overweight), and weight control behavior (no weight control behavior, appropriate weight control behavior, inappropriate weight control behavior). The risk of problematic Internet use was assessed with the Korean Internet Addiction Proneness Scale for Youth-Short Form. Both boys and girls with inappropriate weight control behavior were more likely to have problematic Internet use. Underweight, overweight, and obese boys and girls were more likely to have problematic Internet use. For both boys and girls, subjective perception of underweight and overweight were positively associated with problematic Internet use. Given the negative effect of inappropriate weight control behavior, special attention needs to be given to adolescents' inappropriate weight control behavior, and an educational intervention for adolescents to control their weight in healthy ways is needed.

Weight management is increasingly considered part of physiotherapists' scope of practice in order to improve patient outcomes by, for example, reducing load on joints, or improving chronic pain. However, interactions with patients involving weight may result in patient perceptions of negative judgement from health professionals, which can result in poorer health outcomes. How physiotherapist/patient interactions involving weight are perceived by patients has not yet been investigated. To explore patients' perceptions of interactions with physiotherapists that involved weight, and investigate how these perceptions may inform physiotherapy practice. Face-to-face interviews with physiotherapy patients, with follow up interviews conducted by telephone. Data were analysed thematically. First interviews were held in a physiotherapy practice with follow up interviews conducted two weeks later. Interviews were audio recorded, transcribed and analysed using an inductive thematic method established by Braun and Clarke. Thirty interviews with 15 patients were analysed. Four main themes relevant to weight were identified: 1) perceptions of being 'in physiotherapy' including pre-conceptions, the physical environment, and exposing the body, 2) emphasis placed on weight in physiotherapy interactions, 3) communication styles, and 4) judgement perception. Some patients perceived negative weight judgements from elements of physiotherapy interactions and environments. Physiotherapists need to be aware of this perception because it may result in poorer patient outcomes and patients avoiding physiotherapy appointments. The results suggest strategies to counteract weight stigma include: adjusting the physical environment of the clinic, portraying an understanding of complex determinants of weight, and employing collaborative, non-judgemental communication styles.

To evaluate the perception of parents or caregivers on the health-related quality of life (HRQOL) of children/adolescents with overweight/obesity and possible factors associated with this perception. This was a cross-sectional study involving 297 caregivers of children and adolescents with normal weight (n=170) and with overweight/obesity (n=127), from public and private schools in the study municipality. HRQOL scores obtained through the Child Health Questionnaire - Parent Form 50 (CHQ-PF50) were compared according to the nutritional status and gender of the children/adolescents. Multiple regression analysis was used to determine the predictive value of studied variables for the variation in HRQOL scores. Parents of children/adolescents with overweight/obesity attributed lower HRQOL scores to their children in the following domains: physical functioning (pnutritional status (β=-0.18; p≤0.01); emotional impact on parents, impact on parents' time (β=0.31; pchildren/adolescents with overweight/obesity was observed in the physical and psychosocial aspects. The nutritional status was the variable with the greatest contribution for the assessment the self-esteem of children and adolescents in this study.

Loi, Natasha M.; Breadsell, Dana

2016-01-01

An experiment was conducted to test for the presence of prejudice towards obesity and whether weight controllability beliefs information reduces this prejudice and impacts on a person’s own healthy eating self-efficacy. The experiment randomly allocated 346 participants (49 males) into one of three conditions: controllable contributors toward obesity condition (e.g., information about personal control about diet and exercise); uncontrollable contributors toward obesity condition (e.g., information about genes, factors in society); and a control condition with no information given. Prejudice was present in 81% of the sample. High prejudice was predicted by low self-efficacy for exercise and weight. Weight controllability beliefs information had no significant effect on prejudice levels or exercise or healthy eating self-efficacy levels. Future research directions are discussed. PMID:26966679

Bariatric surgery patients’ perceptions of weight-related stigma in healthcare settings impair post-surgery dietary adherence

2016-10-01

Full Text Available Background: Weight-related stigma is reported frequently by higher body-weight patients in healthcare settings. Bariatric surgery triggers profound weight loss. This weight loss may therefore alleviate patients’ experiences of weight-related stigma within healthcare settings. In non-clinical settings, weight-related stigma is associated with weight-inducing eating patterns. Dietary adherence is a major challenge after bariatric surgery.Objectives: (1 Evaluate the relationship between weight-related stigma and post-surgical dietary adherence; (2 understand if weight loss reduces weight-related stigma, thereby improving post-surgical dietary adherence; and (3 explore provider and patient perspectives on adherence and stigma in healthcare settings. Design: This mixed methods study contrasts survey responses from 300 postoperative bariatric patients with ethnographic data based on interviews with 35 patients and extensive multi-year participant-observation within a clinic setting. The survey measured experiences of weight-related stigma, including from healthcare professionals, on the Interpersonal Sources of Weight Stigma scale and internalized stigma based on the Weight Bias Internalization Scale. Dietary adherence measures included patient self-reports, non-disordered eating patterns reported on the Disordered Eating after Bariatric Surgery scale, and food frequencies. Regression was used to assess the relationships among post-surgical stigma, dietary adherence, and weight loss. Qualitative analyses consisted of thematic analysis.Results: The quantitative data show that internalized stigma and general experiences of weight-related stigma predict worse dietary adherence, even after weight is lost. The qualitative data show patients did not generally recognize this connection, and health professionals explained it as poor patient compliance.Conclusion: Reducing perceptions of weight-related stigma in healthcare settings and weight bias

The perception of self is an important topic in several disciplines such as ethology, behavioral ecology, psychology, developmental and cognitive neuroscience. Self-perception is investigated by experimentally exposing different species of animals to self-stimuli such as their own image, smell or vocalizations. Here we review more than one hundred studies using these methods in birds, a taxonomic group that exhibits a rich diversity regarding ecology and behavior. Exposure to self-image is the main method for studying self-recognition, while exposing birds to their own smell is generally used for the investigation of homing or odor-based kin discrimination. Self-produced vocalizations - especially in oscine songbirds - are used as stimuli for understanding the mechanisms of vocal coding/decoding both at the neural and at the behavioral levels. With this review, we highlight the necessity to study the perception of self in animals cross-modally and to consider the role of experience and development, aspects that can be easily monitored in captive populations of birds.

According to the Risk Perception Attitude (RPA) framework, classifying people according to their perceptions of disease risk and their self-efficacy beliefs allows us to predict their likelihood for engaging in preventive behaviors. Health interventions can then be targeted according to RPA group. We applied the framework to type 2 diabetes prevention behaviors among American Indians and expanded it to include culture and numeracy. Using a cross-sectional study design, we surveyed a sample of Northern Plains American Indians in a reservation community setting on self-reported perceptions of diabetes risk, objective diabetes risk, self-efficacy, engagement in healthy behaviors, knowledge of diabetes risk factors, and covariates including demographics, numeracy, and cultural identity. We used the RPA framework to classify participants into four groups based on their perceptions of risk and self-efficacy. Analyses of variance and covariance estimated inter-group differences in behaviors associated with type 2 diabetes prevention. Among 128 participants, our only finding consistent with the RPA framework was that self-efficacy and risk perception predicted knowledge about diabetes risk factors. We found limited evidence for the influence of cultural identity within the RPA framework. Overall, participants had lower numeracy skills which tended to be associated with inaccurate perceptions of higher levels of risk. The theoretical framework may benefit from inclusion of further contextual factors that influence these behaviors. Attention to numeracy skills stands out in our study as an important influence on the RPA framework, highlighting the importance of attending to numeracy when targeting and tailoring risk information to participants segmented by the RPA framework.

Full Text Available Abstract Background The prevalence of obesity has reached epidemic proportions worldwide, and is also increasing among public safety professionals like firefighters who are expected to be fit and more active. The present study evaluates the associations among Body Mass Index (BMI, weight perception and cardiovascular risk factors in 768 male career firefighters from two Midwestern states in the United States. Methods A physical examination was performed and fasting blood samples were taken. Cardio-respiratory fitness (CRF was determined from symptom- limited maximal treadmill exercise testing with electrocardiogram (ECG monitoring and estimation of oxygen consumption (metabolic equivalents, METS using the Bruce protocol. A health and lifestyle questionnaire was administered with standardized written instructions for completion. Self-reports of weight perception were extracted from responses to the completed multiple choice questionnaire. Baseline characteristics were described using the mean (standard deviation for continuous variables and frequency for categorical variables. Group comparisons were calculated using analysis of variance (ANOVA. Linear models and logistic regression models were used to adjust for possible confounders. Logistic regression analyses were used to calculate the odds ratios of underestimating one’s weight category. Results A high proportion of overweight and obese male career firefighters underestimate their weight categories (68%. The risk of underestimating one’s weight category increased by 24% with each additional unit of increasing BMI after adjustment for age and CRF. When divided into six groups based on combinations of measured BMI category and weight perception, there were significant differences among the groups for most cardiovascular risk factors. After adjustment for age and BMI, these differences remained statistically significant for CRF, amount of weekly exercise, prevalence of Metabolic Syndrome

Body image (BI) is a multidimensional construct that includes perceptual, attitudinal, behavioural components, and feedback from other people's perception of oneself. The feedback from others and the degree to which one accepts or rejects it can determine self evaluation and perception. Body weight perception is a strong determinant of nutritional habits and weight management among adolescents. One of the barriers to reducing rise in obesity prevalence could be its cultural acceptability in some developing countries. To explore the gender influences on perception of self- and opposite-sex body images (BI), perceived body weight and the actual body weight categories at which discrepancies occur among the perceived BIs in undergraduates. This was a survey of perceptual dimension of BI, perceived body weight and actual body weight carried out in 121 undergraduates aged 21-29 years. Discrepancies occurred between self-perceived BI and each of actual body weight (p= 0.00 at 0.00-0.02 confidence interval (CI)), perceived body weight (p= 0.01 at 0.000-0.02 CI) and self-ideal BI (p= 0.03 at 0.000-0.05 CI) of normal-weight males. Self-perceived BI and perceived body weight also differed in normal-weight females (p= 0.02 at 0.000-0.04 CI). Discrepancies (p= 0.02 at 0.00-0.04 CI) occurred between self-perceived BI and self-ideal BI, and between self-perceived BI and desired BI (p= 0.02 at 0.00-0.04 CI) in overweight females. Gender differences occurred for self-ideal BI (p= 0.00 at 0.00-0.02 CI), ideal image for the opposite sex (IBIOS) (p= 0.02 at 0.00-0.04 CI) and desired BI (p= 0.00 at 0.00-0.02 CI). Normal-weight males perceived their BI differently from their actual body weight, perceived body weight and self-ideal BI whereas normal-weight females perceived their BI differently from only their perceived body weight. Discrepancies occur between self-ideal BI and self-perceived BI, and between self-perceived BI and desired BI in overweight females. There are differential

Improvements in self-image and mood are often reported as outcomes of obesity interventions. However, they may also concurrently influence weight loss, suggesting a reciprocal effect. Although previously reported for overweight women, such relationships were untested in morbidly obese women whose psychosocial responses to treatment may be different, and health-risks greater. Women (N = 161, Meanage = 42 years) with morbid obesity (MeanBMI = 45.1 kg/m(2)) participated in a 6-month, behaviorally based physical activity and nutrition treatment. Significant within-group improvements in weight-loss behaviors (physical activity and eating), weight, body satisfaction, physical self-concept, and depression were found. After controlling for age, mediation analyses indicated that, as a result of the treatment, weight loss was both an outcome and mediator of improvements in body-areas satisfaction and physical self-concept (reciprocal effects), but not depression. Results replicated findings from women with lower degrees of overweight, and suggested that weight-loss treatments emphasize changes in self-perception.

Body image perception depends on anthropometric and psychological factors. Body dissatisfaction is influenced by the socio-cultural environment and is associated with eating disorders and low self-esteem. This study examined the body image perception, the degree of dissatisfaction and the weight status perception inconsistency in relation to sex, weight status and amount of physical activity in a sample of university students. The participants were 734 university students (354 females aged 21.5 ± 2.9 yrs and 380 males aged 22.1 ± 3.6 yrs) recruited from the second year of the Sport Sciences degree program. A self-administered questionnaire was used to acquire socio-demographic and sport participation information. Height, weight, BMI and weight status were considered for each subject. Body image perception was assessed by a silhouette matching technique. A new index, FAI (Feel status minus Actual status Inconsistency), was used to assess weight status perception inconsistency. A large proportion of the sample had normal weight status. On average, females chose as feel status a significantly higher figure than the males (4.7 versus 3.8) and they would have liked to have a significantly thinner figure than the males (3.4 versus 3.6). Therefore, the mean FID (Feel minus Ideal Discrepancy) values (positive in both sexes) were significantly higher in females than in males, meaning higher dissatisfaction. The mean FAI values were positive in females and negative in males, indicating a tendency of the women to overestimate their weight status and of the men to underestimate it. Men were more physically active than women. Less active women showed significantly lower body weight and BMI than more active women. Men less engaged in physical activity showed significantly higher FID than more active men. These results show greater dissatisfaction and higher weight status perception consistency in females than in males among Italian university students examined. Our findings

Self-efficacy is a commonly included cognitive variable in weight-loss trials, but there is little uniformity in its measurement. Weight-loss trials frequently focus on physical activity (PA) and eating behavior, as well as weight loss, but no survey is available that offers reliable measurement of self-efficacy as it relates to each of these targeted outcomes. The purpose of this study was to test the psychometric properties of brief, pragmatic self-efficacy scales specific to PA, healthful eating and weight-loss (4 items each). An adult sample (n=1790) from 28 worksites enrolled in a worksite weight-loss program completed the self-efficacy scale, as well as measures of PA, dietary fat intake, and weight, at baseline, 6-, and 12-months. The hypothesized factor structure was tested through confirmatory factor analysis, which supported the expected factor structure for three latent self-efficacy factors, specific to PA, healthful eating, and weight-loss. Measurement equivalence/invariance between relevant demographic groups, and over time was also supported. Parallel growth processes in self-efficacy factors and outcomes (PA, fat intake, and weight) support the predictive validity of score interpretations. Overall, this initial series of psychometric analyses supports the interpretation that scores on these scales reflect self-efficacy for PA, healthful eating, and weight-loss. The use of this instrument in large-scale weight-loss trials is encouraged. PMID:26619093

Culture as Self-Perception

Directory of Open Access Journals (Sweden)

Kudryavcev V.T.,

2016-12-01

Full Text Available An attempt is made to operationalize the content of the “culture” concept in cultural-historical psychology. It is demonstrated that within its framework the culture appears to be a “social environment”, a system of social standards, rather than mediator of human freedom, as a way of self-perception of a man, which helps to reveal creative potential. According to the author, culture as self-perception, its genesis in this capacity, which results in the development of free man, is the basic idea of cultural-historical psychology. It is noted that culture, both historically and ontogenically, at least, in current historical settings, is initially created in personal form, only this enables it to acquire social significance. Culture does not only bring people together based on some formal characteristic, and within it people become significant for each other. The role of imagination in the formation of self-perception is discussed. An assumption on the availability of genetic relation between imagination and spontaneity is put forward. At that, special emphasis is placed on “experiments on consciousness”, including in the form of inversion, which are conducted by means of art.

Full Text Available Abstract The aim of this study was to test the predictive power of dispositional orientations, general self-efficacy and self-determined motivation on fun and boredom in physical education classes, with a sample of 459 adolescents between 13 and 18 with a mean age of 15 years (SD = 0.88. The adolescents responded to four Likert scales: Perceptions of Success Questionnaire, General Self-Efficacy Scale, Sport Motivation Scale and Intrinsic Satisfaction Questionnaire in Sport. The results showed the structural regression model showed that task orientation and general self-efficacy positively predicted self-determined motivation and this in turn positively predicted more fun and less boredom in physical education classes. Consequently, the promotion of an educational task-oriented environment where learners perceive their progress and make them feel more competent, will allow them to overcome the intrinsically motivated tasks, and therefore they will have more fun. Pedagogical implications for less boredom and more fun in physical education classes are discussed.

Little is known about Latino parents' perceptions of weight-related language in English or Spanish, particularly for counseling obese youth. We sought to identify English and Spanish weight counseling terms perceived by Latino parents across demographic groups as desirable for providers to use, motivating, and inoffensive. Latino parents of children treated at urban safety-net clinics completed surveys in English or Spanish. Parents rated the desirable, motivating, or offensive properties of terms for excess weight using a 5-point scale. We compared parental ratings of terms and investigated the association of parent and child characteristics with parent perceptions of terms. A total of 525 surveys met inclusion criteria (255 English, 270 Spanish). English survey respondents rated "unhealthy weight" and "too much weight for his/her health" the most motivating and among the most desirable and least offensive terms. Spanish survey respondents found "demasiado peso para su salud" highly desirable, highly motivating, and inoffensive, and respondents valued its connection to the child's health. Commonly used clinical terms "overweight"/"sobrepeso" and "high BMI [body mass index]"/"índice de masa corporal alta" were not as desirable or as motivating. "Chubby," "fat," "gordo," and "muy gordo" were the least motivating and most offensive terms. Parents' ratings of commonly used clinical terms varied widely across demographic groups, but more desirable terms had less variability. "Unhealthy weight," "too much weight for his/her health," and its Spanish equivalent, "demasiado peso para su salud," were the most desirable and motivating, and the least offensive terms. Latino parents' positive perceptions of these terms occurred across parent and child characteristics, supporting their use in weight counseling. Copyright © 2017 Academic Pediatric Association.

Cardiovascular risk factors (CVRFs) self-perception by women may be inaccurate. A questionnaire was completed anonymously Online by women who self-reported their personal CVRF levels including age, weight, contraceptive use, menopausal status, smoking, diet and physical activities. Self-perceived risk was matched to actual cardiovascular risk according to the Framingham score. Among 5,240 young and middle-aged women with a high educational level, knowledge of personal CVRFs increased with age, from 51-90% for blood pressure (BP), 22-45% for blood glucose and 15-47% for blood cholesterol levels, between 30 and 65 years, respectively. This knowledge was lower for smoking compared with nonsmoking women: 62.5% vs. 74.5% for BP (P self-perception of individual risk are inaccurate in women.

The Attention-Deficit/ Hyperactivity Disorder (ADHD) is a disorder reflected by significant deficits in multiple domains, interfering with the self-perception and self-esteem of children. However, international studies that assess the relationship between ADHD and self-perception have come to contradictory results, and, in Portugal, this is still a little investigated subject. The present work aims to assess the self-perception in different areas (scholastic competence, athletic competence, physical appearance, behaviour and social acceptance) in children with ADHD, comparing them with a control group. This study also tries to analyze whether the subtype of ADHD could interfere differently with the self-perception. We studied 43 children who had a clinical diagnosis of ADHD and 59 children without this diagnosis. Children with ADHD were divided into different subtypes in view of the revised Conners Scales (Portuguese version). The children completed the Self-Perception Profile for Children. From the analysis of averages comparison, it was found that the group of children with ADHD showed lower values in the different domains of self-perception, with a statistically significant difference in scholastic and behaviour self-perceptions. Regarding the different subtypes of ADHD, the results were not statistically significant, but indicated that children perceive themselves differently depending on the subtype. This discrepancy was most evident in scholastic competence where children predominantly inattentive considered themselves less able than the others. In this study, as in the international literature, children with ADHD have an scholastic and behavioural self-perception statistically inferior to other children of the same age, needing every possible support for a healthy emotional development.

Little research has been performed to examine patient perceptions of weight-related language, especially related to childhood obesity. In this study we assessed parental perceptions of weight-based terminology used by health care providers to describe a child's excess weight and assessed perceived connotations associated with these terms including stigma, blame, and motivation to reduce weight. A national sample of American parents with children aged 2 to 18 years (N = 445) completed an online survey to assess their perceptions of 10 common terms to describe excess body weight in youth (including "extremely obese," "high BMI," "weight problem," "unhealthy weight," "weight," "heavy," "obese," "overweight," "chubby," and "fat"). Parents were asked to use a 5-point rating scale to indicate how much they perceived each term to be desirable, stigmatizing, blaming, or motivating to lose weight. Regression models revealed that the terms "weight" and "unhealthy weight" were rated as most desirable, and "unhealthy weight" and "weight problem" were rated as the most motivating to lose weight. The terms "fat," "obese," and "extremely obese" were rated as the most undesirable, stigmatizing, blaming, and least motivating. Parents' ratings were consistent across sociodemographic variables, body weight, and child's body weight. The results of this study have important implications for the improvement of health care for youth with obesity; it may be advantageous for health care providers to use or avoid using specific weight-based language during discussions about body weight with families. Pediatricians play a key role in obesity prevention and treatment, but their efforts may be undermined by stigmatizing or offensive language that can hinder important discussions about children's health.

Weight perceptions, misperceptions, and dating violence victimization among U.S. adolescents.

Dating violence is a major public health issue among youth. Overweight/obese adolescents experience peer victimization and discrimination and may be at increased risk of dating violence victimization. Furthermore, given the stigma associated with overweight/obesity, perceptions and misperceptions of overweight may be more important than actual weight status for dating violence victimization. This study examines the association of three weight indices (weight status, perceived weight, and weight perception accuracy) with psychological and physical dating violence victimization. The 2010 baseline survey of the 7-year NEXT Generation Health Study used a three-stage stratified clustered sampling design to select a nationally representative sample of U.S. 10th-grade students (n = 1,983). Participants who have had a boyfriend/girlfriend reported dating violence victimization and perceived weight. Weight status was computed from measured height/weight. Weight perception accuracy (accurate/underestimate/overestimate) was calculated by comparing weight status and perceived weight. Gender-stratified regressions examined the association of weight indices and dating violence victimization. Racial/ethnic differences were also examined. The association of weight indices with dating violence victimization significantly differed by gender. Overall, among boys, no associations were observed. Among girls, weight status was not associated with dating violence victimization, nor with number of dating violence victimization acts; however, perceived weight and weight perception accuracy were significantly associated with dating violence victimization, type of victimization, and number of victimization acts. Post hoc analyses revealed significant racial/ethnic differences. White girls who perceive themselves (accurately or not) to be overweight, and Hispanic girls who are overweight, may be at increased risk of dating violence victimization. These findings suggest a targeted approach to

Vohs, K D; Heatherton, T F

2001-12-01

In 4 studies, the authors examined interpersonal perceptions as a function of self-construals and ego threats for those with high and low self-esteem. Previous research (T. F. Heatherton & K. D. Vohs, 2000a) found that after threat, high self-esteem people were rated as less likable by an unacquainted dyad partner, whereas low self-esteem people were rated as more likable. Study I showed that after threat, high self-esteem people seek competency feedback, whereas low self-esteem people seek interpersonal feedback. Study 2 showed that high self-esteem people become more independent after threat, whereas low self-esteem people become more interdependent. Study 3 linked differences in independence versus interdependence to interpersonal evaluations. Study 4 found that differences in independent and interdependent self-construals statistically accounted for differences in likability and personality perceptions of high and low self-esteem people after threat. Thus, the combination of threat and self-esteem alters people's focus on different self-aspects, which consequently leads to different interpersonal appraisals.

A higher tolerance for a larger body size has been associated with obesity in black South African (SA) women. The aim of the present study was to explore perceptions regarding body size and weight loss in a sample of black women from a low-income community in Cape Town, SA. Qualitative pilot study including five focus groups. Data were analysed using thematic analysis. Khayelitsha, Cape Town, SA. Twenty-one black SA women. The majority of participants had positive perceptions of overweight/obesity, which were influenced by community and cultural perceptions, but some inconsistencies were observed as overweight/obesity was also associated with ill health. Participants identified many benefits to weight loss, but due to the association with sickness, they were concerned about being stigmatised in their community. Although participants had knowledge about healthy eating, the main barrier to eating healthily included the perceived higher cost of healthier food and food insecurity. All participants saw exercise as a strategy to lose weight and improve health, and were interested in participating in a community-based exercise intervention, but negative community perceptions and conflicting views regarding who should lead the intervention were identified as barriers. These findings highlight the complexities surrounding participants' perceptions regarding body size, weight loss and weight-loss interventions, and emphasise low socio-economic status as a barrier to change. The study also highlights the strong influence of cultural ideals and community perceptions on personal perceptions. These findings underscore the necessity for culturally appropriate weight-loss interventions in low-income, transitioning communities.

Full Text Available OBJECTIVE: Compare the self-esteem of adolescents with epilepsy and adolescents without epilepsy and relate it to social support and seizure controllability perception. METHOD: The study sample consisted: case participants (34 subjects attending the pediatric epilepsy clinic of University Hospital and control participants (30 subjects from public schools in Campinas-SP. The instruments utilized were: identification card with demographic and epilepsy data, a semi-structured interview on aspects of the disease, and a Self-Esteem Multidimensional Scale. RESULTS: There was no significant difference between the two groups but majority of adolescents with epilepsy presented higher self esteem rate, have knowledge about epilepsy, presented high levels of social support and seizure controllability perception. There was no significant relationship between social support and seizure controllability perception with self-esteem. CONCLUSION: Knowledge about epilepsy, social support such good controllability seizure perception seem are important contingencies for a better evaluation of self esteem in adolescents with epilepsy.

Full Text Available The goal of this study was to explore the predictive validity of physical self-efficacy, social physique anxiety, and physical activity in the self-esteem of students, as well as to investigate potential gender differences. The Rosenberg's Self-Esteem Scale (SES, Physical Self-Efficacy Scale (PSES, Social Physique Anxiety Scale (SPAS, and a short questionnaire about physical activity were administered to a sample of 232 university students. The overall results show that students are moderately physically active (on the average, 2.75 times per week, have moderately high selfesteem and physical self-efficacy and lower social physique anxiety. No gender differences were detected in self-esteem. In other variables, gender differences are significant and mostly in favour of males. The analyses showed that self-esteem correlated positively with physical self-efficacy and physical activity, and negatively with social physique anxiety. The regression analyses indicated that physical selfefficacy, social physique anxiety and female gender were significant predictors of self-esteem. Physical activity was not a significant predictor of self-esteem. Future studies should investigate the relations of body self-perceptions, physical exercise, and domain-specific self-esteem.

Parent-Child Discrepancy on Children's Body Weight Perception: The Role of Attachment Security.

2017-01-01

The discrepancies between parents and their children on the description of the behavior and representations of their children have been shown in various studies. Other researchers have reported the parents' difficulty in correctly identifying the weight status of their children. The purpose of our study was to investigate the parent's attributional accuracy on their children's body weight perception in relation to the children attachment security. It was hypothesized that insecure children's parents have a greater discrepancy with their children compared to secure children with their parents. The research participants were 217 children, aged between 5 and 11 years of both genders, and their parents. The attachment pattern was measured by the SAT of Klagsbrun and Bowlby, with the Italian version of Attili. The children were also shown a set of figure body-drawings with which to measure the perception of their weight status. Parents answered a questionnaire to find out the parental attribution of their children's perception. The results show that the body weight perception of insecure children's parents have a greater discrepancy with their children's body weight perception compared with parentally secure children. In particular, parents of insecure children tend to underestimate the perception of their children. This result is most evident in disorganized children. In addition, the perception of insecure children's parents show a greater correlation with children's actual weight rather than with their children's perception. These results suggest that the discrepancies on the perception of children's body weight between parents and children may be influenced by the poor parental attunement to their children's internal states, which characterizes the insecure parent-child attachment relationship.

The present study assessed the relations between reading anxiety, classroom anxiety, language motivation, and readers' self-perception for a sample of Arab-American students in Arabic classes. The effects of sex, grade, and years studying Arabic on academic achievement were examined as well. Measures were administered to 118 middle school students (56 boys, 62 girls; M age = 13.0 yr., SD = 0.8), and teachers reported academic grades in Arabic. Reading anxiety was significantly correlated with classroom anxiety and reader self-perception. Classroom anxiety scores were significantly correlated with motivation and reader self-perception. Significant positive correlations were found between language motivation and reader self-perception scores, and between years studying Arabic and reader self-perception scores. Boys in the second year of Arabic had significantly lower classroom anxiety than girls, and students in Grade 7 had higher reader self-perception than those in Grade 8. Classroom anxiety, language motivation, and reader self-perception significantly predicted Arabic achievement. Pedagogical implications are discussed.

The effects of spinal cord injury in childhood upon later psychological adjustment were investigated by comparing a group of 86 people injured as children with a control group (matched for time since injury and level of injury) of people injured as adults. It was hypothesized that adolescence is a crucial period in psychological development and that the effect of spinal cord injury on body image, self-concept and social relationships during adolescence will have a long-term negative effect on psychological well-being. However, on overall measures of depression, self-esteem and self-perception, there were no significant differences between the experimental and control groups. Furthermore, there were no significant differences between paraplegics and tetraplegics, between men women, or between those who were involved in a significant intimate relationship and those who were not. These findings support previous research which has suggested that organic variables, such as age at injury and level of injury, are not predictive of long-term psychological adjustment.

The moderating effect of self-efficacy on normal-weight, overweight, and obese children's math achievement: a longitudinal analysis.

Increased body weight is associated with decreased cognitive function in school-aged children. The role of self-efficacy in shaping the connection between children's educational achievement and obesity-related comorbidities has not been examined to date. Evidence of the predictive ability of self-efficacy in children is demonstrated in cognitive tasks, including math achievement scores. This study examined the relationship between self-efficacy and math achievement in normal weight, overweight, and obese children. I hypothesized that overweight and obese children with higher self-efficacy will be less affected in math achievement than otherwise comparable children with lower self-efficacy. I tested this prediction with multilevel growth modeling techniques using the ECLS-K 1998-1999 survey data, a nationally representative sample of children. Increased self-efficacy moderates the link between body weight and children's math achievement by buffering the risks that increased weight status poses to children's cognitive function. My findings indicate that self-efficacy moderates math outcomes in overweight, but not obese, children. Copyright © 2015 Elsevier Ltd. All rights reserved.

Bariatric surgery is recognized as the most effective method for achieving relevant weight loss in subjects with severe obesity. However, there is insufficient knowledge about weight self-regulation and quality of motivation in these patients. The main goal of this study was to characterize the association between the percentage of excess weight loss (%EWL) and the motivation to manage weight, at least 1 year after sleeve gastrectomy (SG). This is an observational longitudinal retrospective study. All patients corresponding to predefined inclusion criteria who underwent SG from January 2008 to July 2010 at a main general hospital were invited. A version of the Treatment Self-Regulation Questionnaire (TSRQ) was used to assess patients' quality of motivation: TSRQ concerning continuing the weight self-management program. Clinical data were collected from patients' records. Overall, 81 patients participated (16 men and 65 women, 25-64 years old). The average body mass index was significantly reduced from 45.3 ± 7.0 kg/m 2 preoperatively to 32.7 ± 6.9 kg/m 2 postoperatively. Autonomous self-regulation was higher than externally controlled self-regulation, regarding motives to keep managing weight after SG. Postoperatively, %EWL correlated negatively with external self-regulation. SG was found to be associated with the quality of motivation for losing weight. External motivations were associated with worse results. These findings support the importance of multiprofessional teams in the assessment and treatment of patients, aiming for the promotion of weight self-regulation after bariatric surgery.

Parent perception of weight and feeding styles are associated with obesity in other racial groups but have not been explored in-depth in Chinese-American preschoolers. Cross-sectional survey of 253 Chinese-American parents with preschoolers was performed in a community clinic. Regression analysis was used to assess relationships between parental perception of weight and feeding styles. Parent under-perception of weight was common but more likely in boys than girls (χ 2  = 4.91, p = 0.03). Pressuring was also greater in boys [adjusted mean difference (95% CI) 0.24 (0.004, 0.49)]. In girls, pressuring was lower for children perceived as overweight [adjusted mean difference in CFQ scores -0.75 (-1.27, -0.23)]; in boys, pressuring was high regardless of perceived child weight. Weight perceptions and feeding styles related to childhood obesity in other groups were identified in Chinese-American families. Parent under-perception of child weight and pressure to eat were more common in boys. These factors should be addressed in Chinese-American preschooler obesity prevention programs.

Being moved by the self and others: influence of empathy on self-motion perception.

Directory of Open Access Journals (Sweden)

Christophe Lopez

Full Text Available BACKGROUND: The observation of conspecifics influences our bodily perceptions and actions: Contagious yawning, contagious itching, or empathy for pain, are all examples of mechanisms based on resonance between our own body and others. While there is evidence for the involvement of the mirror neuron system in the processing of motor, auditory and tactile information, it has not yet been associated with the perception of self-motion. METHODOLOGY/PRINCIPAL FINDINGS: We investigated whether viewing our own body, the body of another, and an object in motion influences self-motion perception. We found a visual-vestibular congruency effect for self-motion perception when observing self and object motion, and a reduction in this effect when observing someone else's body motion. The congruency effect was correlated with empathy scores, revealing the importance of empathy in mirroring mechanisms. CONCLUSIONS/SIGNIFICANCE: The data show that vestibular perception is modulated by agent-specific mirroring mechanisms. The observation of conspecifics in motion is an essential component of social life, and self-motion perception is crucial for the distinction between the self and the other. Finally, our results hint at the presence of a "vestibular mirror neuron system".

Personalised breast screening requires assessment of individual risk of breast cancer, of which one contributory factor is weight. Self-reported weight has been used for this purpose, but may be unreliable. We explore the use of volume of fat in the breast, measured from digital mammograms. Volumetric breast density measurements were used to determine the volume of fat in the breasts of 40,431 women taking part in the Predicting Risk Of Cancer At Screening (PROCAS) study. Tyrer-Cuzick risk using self-reported weight was calculated for each woman. Weight was also estimated from the relationship between self-reported weight and breast fat volume in the cohort, and used to re-calculate Tyrer-Cuzick risk. Women were assigned to risk categories according to 10 year risk (below average =8%) and the original and re-calculated Tyrer-Cuzick risks were compared. Of the 716 women diagnosed with breast cancer during the study, 15 (2.1%) moved into a lower risk category, and 37 (5.2%) moved into a higher category when using weight estimated from breast fat volume. Of the 39,715 women without a cancer diagnosis, 1009 (2.5%) moved into a lower risk category, and 1721 (4.3%) into a higher risk category. The majority of changes were between below average and average risk categories (38.5% of those with a cancer diagnosis, and 34.6% of those without). No individual moved more than one risk group. Automated breast fat measures may provide a suitable alternative to self-reported weight for risk assessment in personalized screening.

In this study, we report that self-perception of fracture risk captures some aspect of fracture risk not currently measured using conventional fracture prediction tools and is associated with improved medication uptake. It suggests that adequate appreciation of fracture risk may be beneficial and lead to greater healthcare engagement and treatment. This study aimed to assess how well self-perception of fracture risk, and fracture risk as estimated by the fracture prediction tool FRAX, related to fracture incidence and uptake and persistence of anti-osteoporosis medication among women participating in the Global Longitudinal study of Osteoporosis in Women (GLOW). GLOW is an international cohort study involving 723 physician practices across 10 countries in Europe, North America and Australia. Aged ≥ 55 years, 60,393 women completed baseline questionnaires detailing medical history, including co-morbidities, fractures and self-perceived fracture risk (SPR). Annual follow-up included self-reported incident fractures and anti-osteoporosis medication (AOM) use. We calculated FRAX risk without bone mineral density measurement. Of the 39,241 women with at least 1 year of follow-up data, 2132 (5.4%) sustained an incident major osteoporotic fracture over 5 years of follow-up. Within each SPR category, risk of fracture increased as the FRAX categorisation of risk increased. In GLOW, only 11% of women with a lower baseline SPR were taking AOM at baseline, compared with 46% of women with a higher SPR. AOM use tended to increase in the years after a reported fracture. However, women with a lower SPR who were fractured still reported lower AOM rates than women with or without a fracture but had a higher SPR. These results suggest that SPR captures some aspect of fracture risk not currently measured using conventional fracture prediction tools and is also associated with improved medication uptake.

A rising number of low-income African-American mothers gain more weight in pregnancy than is recommended, placing them at risk for poor maternal and fetal health outcomes. Little is known about the perceptions of mothers in this population that may influence excessive gestational weight gain. In 2010-2011, we conducted 4 focus groups with 31 low-income, pregnant African-Americans in Philadelphia. Two readers independently coded the focus group transcripts to identify recurrent themes. We identified 9 themes around perceptions that encouraged or discouraged high gestational weight gain. Mothers attributed high weight gain to eating more in pregnancy, which was the result of being hungrier and the belief that consuming more calories while pregnant was essential for babies' health. Family members, especially participants own mothers, strongly reinforced the need to "eat for two" to make a healthy baby. Mothers and their families recognized the link between poor fetal outcomes and low weight gains but not higher gains, and thus, most had a greater pre-occupation with too little food intake and weight gain rather than too much. Having physical symptoms from overeating and weight retention after previous pregnancies were factors that discouraged higher gains. Overall, low-income African-American mothers had more perceptions encouraging high gestational weight gain than discouraging it. Interventions to prevent excessive weight gain need to be sensitive to these perceptions. Messages that link guideline recommended weight gain to optimal infant outcomes and mothers' physical symptoms may be most effective for weight control.

Previous research suggests that people show increased self-referential processing when they provide criticism to others, and that this self-referential processing can have negative effects on interpersonal perceptions and behavior. The current research hypothesized that adopting a self-distanced perspective (i.e. thinking about a situation from a non-first person point of view), as compared with a typical self-immersed perspective (i.e. thinking about a situation from a first-person point of view), would reduce self-referential processing during the provision of criticism, and in turn improve interpersonal perceptions and behavior. We tested this hypothesis in an interracial context since research suggests that self-referential processing plays a role in damaging interracial relations. White participants prepared for mentorship from a self-immersed or self-distanced perspective. They then conveyed negative and positive evaluations to a Black mentee while electroencephalogram (EEG) was recorded. Source analysis revealed that priming a self-distanced (vs self-immersed) perspective predicted decreased activity in regions linked to self-referential processing (medial prefrontal cortex; MPFC) when providing negative evaluations. This decreased MPFC activity during negative evaluations, in turn, predicted verbal feedback that was perceived to be more positive, warm and helpful. Results suggest that self-distancing can improve interpersonal perceptions and behavior by decreasing self-referential processing during the provision of criticism. © The Author (2016).

University students may experience significant environmental changes that exert a negative influence on the quality of their diet and lifestyle. There is scarcity of data concerning the dietary and lifestyle behaviors and weight status of students in the health field in North Lebanon. To investigate these data, a cross-sectional survey was conducted including 369 health sciences students aged 18–25 chosen from four public and private universities in North Lebanon. Data were collected using a standardized interview questionnaire to determine sociodemographic, dietary, and lifestyle behaviors, appetite changes, stress related dietary behaviors, and food cravings, as well as self-perceptions of dietary adequacy, physical activity levels, and weight status. Body mass index was assessed. Results had revealed significant differences in some of the dietary consumption patterns and weight status among seniors compared to juniors. However, the overall prevalence of overweight and obesity recorded 32.2% and the dietary consumption patterns fall below recommended levels. Multivariate regression analysis showed that parental obesity, comfort eating, increased appetite, food cravings, and stressful eating were associated with increased risk of obesity while a healthy diet score was associated with decreased risk. The study's findings call for tailoring culture specific intervention programs which enable students to improve their dietary and lifestyle behaviors and control stress. PMID:27429989

The structure of conscious bodily self-perception during full-body illusions.

Dobricki, Martin; de la Rosa, Stephan

2013-01-01

Previous research suggests that bodily self-identification, bodily self-localization, agency, and the sense of being present in space are critical aspects of conscious full-body self-perception. However, none of the existing studies have investigated the relationship of these aspects to each other, i.e., whether they can be identified to be distinguishable components of the structure of conscious full-body self-perception. Therefore, the objective of the present investigation is to elucidate the structure of conscious full-body self-perception. We performed two studies in which we stroked the back of healthy individuals for three minutes while they watched the back of a distant virtual body being synchronously stroked with a virtual stick. After visuo-tactile stimulation, participants assessed changes in their bodily self-perception with a custom made self-report questionnaire. In the first study, we investigated the structure of conscious full-body self-perception by analyzing the responses to the questionnaire by means of multidimensional scaling combined with cluster analysis. In the second study, we then extended the questionnaire and validated the stability of the structure of conscious full-body self-perception found in the first study within a larger sample of individuals by performing a principle components analysis of the questionnaire responses. The results of the two studies converge in suggesting that the structure of conscious full-body self-perception consists of the following three distinct components: bodily self-identification, space-related self-perception (spatial presence), and agency.

Self-motion perception after a sudden stop from a sustained rotation in darkness lasts approximately as long as reflexive eye movements. We hypothesized that, after an angular velocity step, self-motion perception and reflexive eye movements are driven by the same vestibular pathways. In 16 healthy subjects (25-71 years of age), perceived rotational velocity (PRV) and the vestibulo-ocular reflex (rVOR) after sudden decelerations (90°/s(2)) from constant-velocity (90°/s) earth-vertical axis rotations were simultaneously measured (PRV reported by hand-lever turning; rVOR recorded by search coils). Subjects were upright (yaw) or 90° left-ear-down (pitch). After both yaw and pitch decelerations, PRV rose rapidly and showed a plateau before decaying. In contrast, slow-phase eye velocity (SPV) decayed immediately after the initial increase. SPV and PRV were fitted with the sum of two exponentials: one time constant accounting for the semicircular canal (SCC) dynamics and one time constant accounting for a central process, known as velocity storage mechanism (VSM). Parameters were constrained by requiring equal SCC time constant and VSM time constant for SPV and PRV. The gains weighting the two exponential functions were free to change. SPV were accurately fitted (variance-accounted-for: 0.85 ± 0.10) and PRV (variance-accounted-for: 0.86 ± 0.07), showing that SPV and PRV curve differences can be explained by a greater relative weight of VSM in PRV compared with SPV (twofold for yaw, threefold for pitch). These results support our hypothesis that self-motion perception after angular velocity steps is be driven by the same central vestibular processes as reflexive eye movements and that no additional mechanisms are required to explain the perceptual dynamics.

To propose a simple correction of body-mass index (BMI) based on self-reported weight and height (reported BMI) using gender, body shape perception and socioeconomic status in an adolescent population. 341 boys and girls aged 17-18 years were randomly selected from a representative sample of 2165 French adolescents living in Paris surveyed in 2010. After an anonymous self-administered pen-and-paper questionnaire asking for height, weight, body shape perception (feeling too thin, about the right weight or too fat) and socioeconomic status, subjects were measured and weighed. BMI categories were computed according to Cole's cut-offs. Reported BMIs were corrected using linear regressions and ROC analyses and checked with cross-validation and multiple imputations to handle missing values. Agreement between actual and corrected BMI values was estimated with Kappa indexes and Intraclass correlation coefficients (ICC). On average, BMIs were underreported, especially among girls. Kappa indexes between actual and reported BMI were low, especially for girls: 0.56 95%CI = [0.42-0.70] for boys and 0.45 95%CI = [0.30-0.60] for girls. The regression of reported BMI by gender and body shape perception gave the most balanced results for both genders: the Kappa and ICC obtained were 0.63 95%CI = [0.50-0.76] and 0.67, 95%CI = [0.58-0.74] for boys; 0.65 95%CI = [0.52-0.78] and 0.74, 95%CI = [0.66-0.81] for girls. The regression of reported BMI by gender and socioeconomic status led to similar corrections while the ROC analyses were inaccurate. Using body shape perception, or socioeconomic status and gender is a promising way of correcting BMI in self-administered questionnaires, especially for girls.

The present study investigated the effect of sexually objectifying music video exposure on young women's implicit bodily self-perception and the moderating role of self-esteem. Fifty-six college women of normal weight were either exposed to three sexually objectifying music videos or three neutral music videos. Perceived and ideal body size were measured both before and after video exposure, using horizontally stretched and compressed photographs of the participant's own body in swimming garment. As expected, only women low (but not high) in self-esteem were negatively affected by the sexually objectifying content of the music videos: they perceived themselves as bigger and showed an increased discrepancy between their perceived and ideal body size after video exposure. The neutral music videos did not influence women's bodily self-perceptions. These findings suggest that body image is a flexible construct, and that high self-esteem can protect women against the adverse effects of sexually objectifying media. Copyright © 2012 Elsevier Ltd.

Does chronic idiopathic dizziness reflect an impairment of sensory predictions of self-motion?

Directory of Open Access Journals (Sweden)

Joern K Pomper

2013-11-01

Full Text Available Most patients suffering from chronic idiopathic dizziness do not present signs of vestibular dysfunction or organic failures of other kinds. Hence, this kind of dizziness is commonly seen as psychogenic in nature, sharing commonalities with specific phobias, panic disorder and generalized anxiety. A more specific concept put forward by Brandt and Dieterich (1986 states that these patients suffer from dizziness because of an inadequate compensation of self-induced sensory stimulation. According to this hypothesis self-motion-induced reafferent visual stimulation is interpreted as motion in the world since a predictive signal reflecting the consequences of self-motion, needed to compensate the reafferent stimulus, is inadequate. While conceptually intriguing, experimental evidence supporting the idea of an inadequate prediction of the sensory consequences of own movements has as yet been lacking. Here we tested this hypothesis by applying it to the perception of background motion induced by smooth-pursuit eye movements. As a matter of fact, we found the same mildly undercompensating prediction, responsible for the perception of slight illusory world motion („Filehne illusion in the 15 patients tested and their age-matched controls. Likewise, the ability to adapt this prediction to the needs of the visual context was not deteriorated in patients. Finally, we could not find any correlation between measures of the individual severity of dizziness and the ability to predict. In sum, our results do not support the concept of a deviant prediction of self-induced sensory stimulation as cause of chronic idiopathic dizziness.

Self-evaluations or self-perceptions of creativity have been used in the past both as predictors of creative performance and as criteria. Four measures utilizing self-perceptions of creativity were assessed for their usefulness as criterion measures of creativity. Analyses provided evidence of domain specificity of self-perceptions.

Those with self-beliefs in negative aging may desire a stronger support network to buffer against potential threats and may hence see their current network as less than adequate. This study investigated whether negative self-perception of aging is associated with increased dissatisfaction with children's support. Six hundred and forty Chinese older adults with at least one child and a total of 2,108 adult children rated the degree of support received from each child individually and the degree to which it met their expectation. Additionally, the participants responded to measures of self-perception of aging (both positive and negative), neuroticism, instrumental activities of daily living, chronic illnesses, financial strain, and living status. The multilevel dataset was analyzed using mixed-effects regression. Individuals who had a more negative self-perception of aging, who were younger, who lived alone, and who had fewer children provided lower support satisfaction ratings after support received from children was controlled for. Positive self-perception of aging was unrelated to support satisfaction. Neuroticism did not account for the relationship between negative self-perception of aging and support satisfaction. A negative self-perception of aging may create vulnerability to intergenerational tension that puts older people at risk of adverse psychological and physical health outcomes. © The Author 2016.

Using technology to self-monitor body weight, dietary intake, and physical activity is a common practice used by consumers and health companies to increase awareness of current and desired behaviors in weight loss. Understanding how to best use the information gathered by these relatively new methods needs to be further explored. The purpose of this study was to analyze the contribution of self-monitoring to weight loss in participants in a 6-month commercial weight-loss intervention administered by Retrofit and to specifically identify the significant contributors to weight loss that are associated with behavior and outcomes. A retrospective analysis was performed using 2113 participants enrolled from 2011 to 2015 in a Retrofit weight-loss program. Participants were males and females aged 18 years or older with a starting body mass index of ≥25 kg/m2, who also provided a weight measurement at the sixth month of the program. Multiple regression analysis was performed using all measures of self-monitoring behaviors involving weight measurements, dietary intake, and physical activity to predict weight loss at 6 months. Each significant predictor was analyzed in depth to reveal the impact on outcome. Participants in the Retrofit Program lost a mean -5.58% (SE 0.12) of their baseline weight with 51.87% (1096/2113) of participants losing at least 5% of their baseline weight. Multiple regression model (R 2 =.197, Pself-monitoring behaviors of self-weigh-in, daily steps, high-intensity activity, and persistent food logging were significant predictors of weight loss during a 6-month intervention. ©Stefanie Lynn Painter, Rezwan Ahmed, James O Hill, Robert F Kushner, Richard Lindquist, Scott Brunning, Amy Margulies.

Fast food restaurants have become widespread in both developed and developing countries due to nutritional and economic transitions. The frequency of fast food intake is relatively high among adolescents; however, fast food consumption is positively associated with total energy intake and obesity in adolescents. This study aimed to examine the perception of Jordanian adolescents towards fast foods relative to gender and obesity. A cross-sectional survey was conducted on 400 boys and 395 girls, aged 15-18 years. The adolescents completed a validated questionnaire to measure the perception of adolescents towards fast foods during the year 2013-2014. Weight and height were measured. Numbers who were non-overweight, overweight, and obese were calculated for each age and sex using the International Obesity Task Force (IOTF) standard. The majority of participants perceived foods which are eaten as sandwiches as fast foods. A significant difference between boy and girl adolescents was reported regarding perception of French fries ( p fast foods. Girls were significantly more enthusiastic than boys to consider cuscusi plate ( p foods ( p foods ( p foods ( p foods ( p fast foods. The difference between obese and non-obese regarding the perception of fast foods was only significant among boy participants. Western or non-Arab foods, food prepared fast and eaten fast in self-service outlets, and food rich in calories were significantly perceived as fast food by Jordanian adolescents ( p foods as fast foods or non-fast foods was significantly different between both genders as well as in obese and non-obese male Jordanian adolescents.

Parent–Child Discrepancy on Children’s Body Weight Perception: The Role of Attachment Security

Full Text Available The discrepancies between parents and their children on the description of the behavior and representations of their children have been shown in various studies. Other researchers have reported the parents’ difficulty in correctly identifying the weight status of their children. The purpose of our study was to investigate the parent’s attributional accuracy on their children’s body weight perception in relation to the children attachment security. It was hypothesized that insecure children’s parents have a greater discrepancy with their children compared to secure children with their parents. The research participants were 217 children, aged between 5 and 11 years of both genders, and their parents. The attachment pattern was measured by the SAT of Klagsbrun and Bowlby, with the Italian version of Attili. The children were also shown a set of figure body-drawings with which to measure the perception of their weight status. Parents answered a questionnaire to find out the parental attribution of their children’s perception. The results show that the body weight perception of insecure children’s parents have a greater discrepancy with their children’s body weight perception compared with parentally secure children. In particular, parents of insecure children tend to underestimate the perception of their children. This result is most evident in disorganized children. In addition, the perception of insecure children’s parents show a greater correlation with children’s actual weight rather than with their children’s perception. These results suggest that the discrepancies on the perception of children’s body weight between parents and children may be influenced by the poor parental attunement to their children’s internal states, which characterizes the insecure parent–child attachment relationship.

Two-year study relating adolescents' self-concept and gender role perceptions to achievement and attitudes toward science

Science.gov (United States)

Handley, Herbert M.; Morse, Linda W.

To assess the developmental relationship of perceptions of self-concept and gender role identification with adolescents' attitudes and achievement in science, a two-year longitudinal study was conducted. A battery of instruments assessing 16 dimensions of self-concept/gender role identifications was employed to predict students' achievement and attitudes toward science. Specific behaviors studied included self-concept in school and science and mathematics, attitudes toward appropriate gender roles in science activities and careers, and self-perceptions of masculine and feminine traits. One hundred and fifty-five adolescents, enrolled, respectively, in the seventh and eighth grades, participated in the study. Through Fisher z transformations of correlation coefficients, differences in relationships between these two sets of variables were studied for males and females during the two years. Results indicated that students' self-concepts/gender role perceptions were related to both achievement and attitudes toward science, but more related to attitudes than achievement. These relationships became more pronounced for students as they matured from seventh to eighth graders.

Anorexia nervosa is a severe psychiatric illness characterized by intense fear of gaining weight, relentless pursuit of thinness, deep concerns about food and a pervasive disturbance of body image. Functional magnetic resonance imaging tries to shed light on the neurobiological underpinnings of anorexia nervosa. This review aims to evaluate the empirical neuroimaging literature about self-perception in anorexia nervosa. This narrative review summarizes a number of task-based and resting-state functional magnetic resonance imaging studies in anorexia nervosa about body image and self-perception. The articles listed in references were searched using electronic databases (PubMed and Google Scholar) from 1990 to February 2016 using specific key words. All studies were reviewed with regard to their quality and eligibility for the review. Differences in brain activity were observed using body image perception and body size estimation tasks showing significant modifications in activity of specific brain areas (extrastriate body area, fusiform body area, inferior parietal lobule). Recent studies highlighted the role of emotions and self-perception in anorexia nervosa and their neural substrate involving resting-state networks and particularly frontal and posterior midline cortical structures within default mode network and insula. These findings open new horizons to understand the neural substrate of anorexia nervosa. © 2016 The British Psychological Society.

Précis of Social Perception and Social Reality: Why accuracy dominates bias and self-fulfilling prophecy.

Science.gov (United States)

Jussim, Lee

2017-01-01

Social Perception and Social Reality (Jussim 2012) reviews the evidence in social psychology and related fields and reaches three conclusions: (1) Although errors, biases, and self-fulfilling prophecies in person perception are real, reliable, and occasionally quite powerful, on average, they tend to be weak, fragile, and fleeting. (2) Perceptions of individuals and groups tend to be at least moderately, and often highly accurate. (3) Conclusions based on the research on error, bias, and self-fulfilling prophecies routinely greatly overstate their power and pervasiveness, and consistently ignore evidence of accuracy, agreement, and rationality in social perception. The weight of the evidence - including some of the most classic research widely interpreted as testifying to the power of biased and self-fulfilling processes - is that interpersonal expectations relate to social reality primarily because they reflect rather than cause social reality. This is the case not only for teacher expectations, but also for social stereotypes, both as perceptions of groups, and as the bases of expectations regarding individuals. The time is long overdue to replace cherry-picked and unjustified stories emphasizing error, bias, the power of self-fulfilling prophecies, and the inaccuracy of stereotypes, with conclusions that more closely correspond to the full range of empirical findings, which includes multiple failed replications of classic expectancy studies, meta-analyses consistently demonstrating small or at best moderate expectancy effects, and high accuracy in social perception.

Weight self-regulation process in adolescence: the relationship between control weight attitudes, behaviors and body weight status

Full Text Available Adolescents’ self-control weight behaviors were assessed (n= 1961; 12-17 years old; 2007-2008 in the Balearic Islands, Spain. The study analyzed the relationships between body weight status, body image and self-weight concern, and actual attempts to lose weight by restrained eating and/or increased exercising. In terms of regulatory focus theory (RFT, we considered that efforts to lose or to maintain weight (successful or failed would be motivated either by a promotion focus (to show an attractive body, a prevention focus (to avoid social rejection of fatness, or both. Results showed that 41% of overweight boys and 25% of obese boys stated that they had never made any attempt to lose weight, and 13% and 4% in females. Around half of overweight boys and around a quarter of obese boys stated that they were Not at all concerned about weight gain, and girls’ percentages decreased to 13% and 11% respectively. By contrast 57% of normal weight girls monitored their weight and stated that they had tried to slim at least once. Weight self-regulation in females attempted to combine diet and exercise, while boys relied almost exclusively on exercise. Apparent lack of consciousness of body weight status among overweight boys, and more important, subsequent absence of behaviors to reduce their weight clearly challenges efforts to prevent obesity. We argue that several causes may be involved in this outcome, including unconscious emotional (self-defense and cognitive (dissonance mechanisms driven by perceived social stigmatization of obesity. The active participation of social values of male and female body image (strong vs. pretty and the existence of social habituation to overweight are suggested. A better knowledge of psychosocial mechanisms underlying adolescent weight self-control may improve obesity epidemics.

A dual systems account of visual perception: Predicting candy consumption from distance estimates.

Science.gov (United States)

Krpan, Dario; Schnall, Simone

2017-04-01

A substantial amount of evidence shows that visual perception is influenced by forces that control human actions, ranging from motivation to physiological potential. However, studies have not yet provided convincing evidence that perception itself is directly involved in everyday behaviors such as eating. We suggest that this issue can be resolved by employing the dual systems account of human behavior. We tested the link between perceived distance to candies and their consumption for participants who were tired or depleted (impulsive system), versus those who were not (reflective system). Perception predicted eating only when participants were tired (Experiment 1) or depleted (Experiments 2 and 3). In contrast, a rational determinant of behavior-eating restraint towards candies-predicted eating for non-depleted individuals (Experiment 2). Finally, Experiment 3 established that perceived distance was correlated with participants' self-reported motivation to consume candies. Overall, these findings suggest that the dynamics between perception and behavior depend on the interplay of the two behavioral systems. Copyright © 2017 Elsevier B.V. All rights reserved.

The authors examined the relationship of authoritarian, authoritative, and permissive parenting styles and the number of years in the United States with self-perception (academic competence, morality, and self-reliance) as recalled by Korean American college students (N = 144). Authoritative parenting behaviors were most common in Korean American families, followed by authoritarian behaviors, with permissive behaviors a distant 3rd. Authoritative parenting styles and the number of years lived in the United States were predictive of higher academic competence. Authoritarian and permissive parenting styles were predictive of lower self-reliance, whereas number of years lived in the United States was related to higher self-reliance. Those findings provide partial support for generalizing D. Baumrind's (1971) model of parenting styles to Korean American families, and the findings demonstrate the importance of considering acculturation issues in parenting studies.

Teixeira, Pedro J; Silva, Marlene N; Mata, Jutta; Palmeira, António L; Markland, David

2012-03-02

This article explores the topics of motivation and self-regulation in the context of weight management and related behaviors. We focus on the role of a qualitative approach to address motivation--not only considering the level but also type of motivation--in weight control and related behaviors. We critically discuss the operationalization of motivation in current weight control programs, present a complementary approach to understanding motivation based on self-determination theory, and review empirical findings from weight control studies that have used self-determination theory measures and assessed their association with weight outcomes. Weight loss studies which used Motivational Interviewing (MI) are also reviewed, considering MI's focus on enhancing internal motivation. We hypothesize that current weight control interventions may have been less successful with weight maintenance in part due to their relative disregard of qualitative dimensions of motivation, such as level of perceived autonomy, often resulting in a motivational disconnect between weight loss and weight-related behaviors. We suggest that if individuals fully endorse weight loss-related behavioral goals and feel not just competent but also autonomous about reaching them, as suggested by self-determination theory, their efforts are more likely to result in long-lasting behavior change.

Full Text Available Recognising overweight and obesity is critical to prompting action, and consequently preventing and treating obesity. The present study examined the association between parental perceptions of child weight status and child's diet.Participants were members of the Gateshead Millennium Study. Parental perception of their child's weight status was assessed using a questionnaire and compared against International Obesity Task Force cut-offs for childhood overweight and obesity when the children were aged 6-8 years old. Diet was assessed at age 6-8years old using the FAST (Food Assessment in Schools Tool food diary method. The association between parental perception and dietary patterns as defined by Principal Components Analysis, was assessed using multivariate regression after adjustment for child's gender, child's weight status, maternal body mass index (BMI, maternal education and deprivation status.Of the 361 parents who provided complete data on confounders and on their perception of their child's weight status, 63 (17% parents perceived their child as being of 'normal' weight or 'overweight' when they were actually 'overweight' or 'obese', respectively. After adjustment for confounders, parents who misperceived their child's weight had children with a lower 'healthy' dietary pattern score compared to children whose parents correctly perceived their weight (β = -0.88; 95% CI: -1.7, -0.1; P-value = 0.028. This association was found despite higher consumption of reduced sugar carbonated drinks amongst children whose parents incorrectly perceived their weight status compared to children whose parents perceived their weight correctly (52.4% vs. 33.6%; P-value = 0.005.In conclusion, children whose parents did not correctly perceive their weight status scored lower on the 'healthy' dietary pattern. Further research is required to define parents' diets based on their perception status and to examine if a child's or parent's diet mediates the

Peer relationships account for a significant motivational influence on sport participation among youth athletes with and without disabilities. The primary purpose of this study was to determine if the quality of friendships, physical self-perceptions and general self-worth predicted close friendship, loneliness and social acceptance among 46 athletes with physical disabilities (males = 35, female = 11) between the ages of 12 and 21 (M age = 15.37, SD = 2.45). Second, this study examined descriptive information on the quality of friendships inside and outside of an adapted sport setting, feelings of loneliness, social acceptance, close friendships, athletic competence, physical appearance, and self-worth among youth athletes with physical disabilities. Participants completed the Sport Friendship Quality Scale (SFQS), a Loneliness Rating Scale and the Self-Perception Profile for Adolescents (SPPA). Three regression analyses used positive and negative aspects of non-sport friendship quality, positive aspects of sport friendship quality, physical appearance, athletic competence, and self-worth as predictors and accounted for 57%, 41%, and 31% of the variance in loneliness, close friendships, and social acceptance, respectively. Athletic competence and self-worth were the most important predictors of loneliness and close friendships with significant (p e., self-worth) and sport specific psychological (i.e., athletic competence) constructs in predicting important social well-being indices (i.e., close friendships & loneliness).

Parents have a fundamental role in promoting the healthy weight of their children. To determine parental perceptions of their child's body weight, eating and physical activity (PA) behaviours, and to test a predictive model of parental perceptions regarding their child's PA and healthy eating behaviours. A random-digit telephone survey was conducted among parents of children four to 12 years of age living in the Champlain region of Ontario. Descriptive statistics were used to summarize the responses. Path analysis was used to identify predictors of parental perceptions of PA and healthy eating. The study sample consisted of 1940 parents/caregivers. Only 0.2% of parents reported their child as being obese; 8.6% reported their child as being overweight. Most parents perceived their child to be physically active and eating healthily. Approximately 25% of parents reported that their child spent 2 h/day or more in front of a screen, and that their child consumed less than three servings of fruits and vegetables daily, and regularly consumed fast food. Variables that correlated with PA perceptions included time spent reading/doing homework, interest in PA, perceived importance of PA, frequency of PA, level of parental PA, participation in organized sport, child weight and parental concern for weight. Variables that predicted perceptions regarding healthy eating were parental education, household income, preparation of home-cooked meals, fruit and vegetable intake, and concern for and influence on the child's weight. Parents in the present study sample did not appear to understand, or had little knowledge of the recommendations for PA and healthy eating in children. Parents appeared to base their judgment of healthy levels of PA or healthy eating behaviours using minimal criteria; these criteria are inconsistent with those used by health professionals to define adequate PA and healthy eating. The present survey highlights an important knowledge gap between scientific

Full Text Available Alexithymia, defined as difficulty in describing or recognizing emotions, has been shown to be connected with psoriasis, but its relationship with self-management of psoriasis has not been explored. The aim of this study was to assess the frequency of alexithymia and its relationship with self-management and illness perception in the context of psoriasis. A total of 163 patients participating in 3 weeks of climate heliotherapy (CHT at Gran Canaria were assessed for alexithymia using the Toronto Alexithymia Scale (TAS-20 at baseline. Self-reported measures for self-management (Health Education Impact Questionnaire; heiQ, and disease severity and illness perception (Brief Illness Perception Questionnaire; BIPQ were assessed twice. Of all patients, 14.1% were characterized as alexithymic and 22.1% scored in the intermediate range. Alexithymic patients scored significantly worse in all heiQ domains, and reported worse illness perception. However, there were no between-group differences in heiQ or BIPQ change from baseline to after CHT. In conclusion, this study shows that alexithymia indicates inferior self-management and reaffirms the associations with illness perception. Further research is required into these relationships.

Many with schizophrenia have been found to experience difficulties recognizing a range of their own mental states including memories and emotions. While there is some evidence that the self perception of empathy in schizophrenia is often at odds with objective observations, little is known about the correlates of rates of concordance between self and rater assessments of empathy for this group. To explore this issue we gathered self and rater assessments of empathy in addition to assessments of emotion recognition using the Bell Lysaker Emotion Recognition Task, insight using the Scale to Assess Unawareness of Mental Disorder, and symptoms using the Positive and Negative Syndrome Scale from 91 adults diagnosed with schizophrenia spectrum disorders. Results revealed that participants with better emotion recognition, better insight, fewer positive symptoms and fewer depressive symptoms produced self ratings of empathy which were more strongly correlated with assessments of empathy performed by raters than participants with greater deficits in these domains. Results suggest that deficits in emotion recognition along with poor insight and higher levels of positive and depressive symptoms may affect the degree of agreement between self and rater assessments of empathy in schizophrenia.

There is a broad semantic network of aging stereotypes; where different concepts and their measurement are confused: personal stereotypes, self-stereotypes and self-perception of aging. First, we analyze the translated version of the Image of Aging Scale (IAS) measurement model through exploratory and confirmatory factor analysis, with two representative sub-samples of the Spanish population aged over eighteen (N = 1,105) and in a sample of gerontologists and geriatricians (N = 325). Second, in an effort to disentangle the theoretical relationships between personal stereotypes, self-stereotypes and self-perception of aging, both the IAS (with different instructions) and Lawton’s 5-item scale were administered to a representative sample of Spanish people over 50. Our results indicate that the Spanish version of the IAS has a similar psychometric structure to that proposed by the authors. Furthermore, the factorial structure (equal form and metric invariance) is replicated in both samples, but latent means and factor correlations were higher in the professional group. We discuss Levy’s theoretical assumptions about personal-stereotypes and the self-stereotype measured with IAS and their relationship to self-perception of ageing.

Perceptions of Weight and Health Practices in Hispanic Children: A Mixed-Methods Study

Full Text Available Background. Perception of weight by parents of obese children may be associated with willingness to engage in behavior change. The relationship between parents’ perception of their child’s weight and their health beliefs and practices is poorly understood, especially among the Hispanic population which experiences disparities in childhood obesity. This study sought to explore the relationship between perceptions of weight and health beliefs and practices in a Hispanic population. Methods. A cross-sectional, mixed-methods approach was used with semistructured interviews conducted with parent-child (2–5 years old dyads in a primarily Hispanic, low-income population. Parents were queried on their perceptions of their child’s health, health practices, activities, behaviors, and beliefs. A grounded theory approach was used to analyze participants’ discussion of health practices and behaviors. Results. Forty parent-child dyads completed the interview. Most (58% of the parents of overweight and obese children misclassified their child’s weight status. The qualitative analysis showed that accurate perception of weight was associated with internal motivation and more concrete ideas of what healthy meant for their child. Conclusions. The qualitative data suggest there may be populations at different stages of readiness for change among parents of overweight and obese children, incorporating this understanding should be considered for interventions.

Effects of fitness and self-confidence on time perception during exertion

Directory of Open Access Journals (Sweden)

2015-09-01

Full Text Available Aims: Human physical and psychological features influence perceptions of the environment during activity. If during exercise an individual over-estimates time, they may interpret this as spending longer than necessary under a potentially aversive state of exertion. This may in turn decrease one’s sense of exercise success and tendency to persevere with exercise. We tested if experimentally manipulating sense of exercise self-efficacy would affect time perception during standardised physical exertion. Method: Exercise Self-Efficacy (ESE of 18 -73 year olds (N=51 was measured before and after an exercise challenge of moderate intensity. Height, weight and body fat composition were measured before participants were randomly allocated to one of three groups. After a 4-minute treadmill fitness test, participants were presented with either bogus feedback about their performance (positive or negative or no feedback (control. Before and during exercise, participants estimated a prescribed 2-minute time interval. Ratings of perceived exertion were also measured periodically. Results: Feedback on performance had no significant effect on time perception, even when controlling for individual exertion level. Reported ESE was also unaffected by whether someone received positive, negative or no feedback. Age was again found to be significantly correlated with VO2max, r(51 = .62, p < .001, but in contrast to prior findings, estimates of general fitness such as VO2max, BMI and waist circumference were unrelated to changes in time perception due to exertion. Conclusions: These findings failed to support prior findings and anecdotal evidence suggesting that exertion might alter one’s perception of time. We also failed to find any support for effects on ESE when participants were given explicit performance feedback. Finally, participants’ physical characteristics appear to be unrelated to time perception whilst exercising at moderate intensity.

2009-08-01

The objective of the present work was to quantify mothers' misclassification of pre-school children's weight status and to determine factors associated with the maternal misperception. A representative sample of 2287 children aged 2-5 years was examined (GENESIS study). Mothers' perceptions of their child's weight status and the children's and mothers' anthropometric and other characteristics (sociodemographic and lifestyle) were recorded. Almost 38 % of mothers underestimated their child's weight status. The frequency of underestimation was much higher among 'at risk of being overweight' and 'overweight' children (88.3 % and 54.5 %, respectively) compared with 'underweight/normal-weight' children (18.0 %, P engaging in physical activity for less than 3 h/week and in children whose mothers had low education status, compared with their counterparts. Moreover, the higher the BMI-for-age Z-score, the greater the odds that the mother would underestimate her child's weight status. The current study demonstrated that more than one-third of mothers misclassify their children's weight status as being lower than the actual. Given that mother's weight perception might be an important determinant of child's body weight development, clinicians and health professionals should help mothers correctly classify their children's weight status, which could potentially help in the early prevention of overweight and obesity.

Weight loss studies which used Motivational Interviewing (MI are also reviewed, considering MI's focus on enhancing internal motivation. We hypothesize that current weight control interventions may have been less successful with weight maintenance in part due to their relative disregard of qualitative dimensions of motivation, such as level of perceived autonomy, often resulting in a motivational disconnect between weight loss and weight-related behaviors. We suggest that if individuals fully endorse weight loss-related behavioral goals and feel not just competent but also autonomous about reaching them, as suggested by self-determination theory, their efforts are more likely to result in long-lasting behavior change.

To explore illness perception and perceived risk of developing diabetes complications in relation to health-promoting self-care behaviors among Chinese patients with type 2 diabetes. Illness and risk perceptions are important determinants of various health behaviors. However, few studies have simultaneously examined the impacts of these two constructs on self-care among diabetic patients. Data were collected on participants' characteristics, illness perception, risk perception, and health-promoting self-care behaviors over 6months among 304 subjects from three general hospitals. Significant associations between illness perception and risk perception were observed. Illness perception and/or risk perception explained an independent, small but significant proportion of the variance in each health-promoting self-care behavior. One's perceptions of illness and future risk might be influential in understanding health-promoting self-care among diabetic patients. It may be useful to improve self-management by tailoring intervention content to individuals' illness-related perceptions. Copyright © 2017 Elsevier Inc. All rights reserved.

Mexican American women experience unique health care needs related to integration of Mexican and American cultures. To learn how to better promote self-care practices and service utilization in women of Mexican origin living in Texas, researchers used a qualitative approach to interview a convenience sample of 11 low-income women attending a health clinic. Researchers collected narrative data about the women's perceptions of health, wellness, and self-care. Using the matrix approach described by Miles and Huberman, we organized findings around women's roles, including participants' descriptions of themselves, their health and wellness awareness, self-care practices for health/illness and wellness/nonwellness, barriers to self-care, origin of self-care practices, and perceptions of life control. Implications for health planning and service delivery are presented.

Full Text Available Objective: To conduct a systematic review of literature about maternal perception of child weight and the factors that are associated with it. Materials and methods: SciELO, PubMed, LILACS and Redalyc were subject to a database search for articles published between 2009 and 2016. The final sample was comprised of twenty five articles. Results: From 21.8% to 98.2% of mothers underestimate the weight of their child. This has been associated with body mass index (BMI, sex, age, birth weight and the quantity of food that is ingested by the child; race, BMI, age, income and maternal education. Furthermore it has been found that the perception of child weight is associated with the presence of childhood obesity, actions and problems of parents to manage the weight of the child and dietary control. Conclusions: It is necessary to continue the study of the maternal perception of the child's weight and to find proposals for intervention aimed at reducing this problem.

The majority of clinical content-based image retrieval (CBIR) studies disregard human perception subjectivity, aiming to duplicate the consensus expert assessment of the visual similarity on example cases. The purpose of our study is twofold: i) discern better the extent of human perception subjectivity when assessing the visual similarity of two images with similar semantic content, and (ii) explore the feasibility of personalized predictive modeling of visual similarity. We conducted a human observer study in which five observers of various expertise were shown ninety-nine triplets of mammographic masses with similar BI-RADS descriptors and were asked to select the two masses with the highest visual relevance. Pairwise agreement ranged between poor and fair among the five observers, as assessed by the kappa statistic. The observers' self-consistency rate was remarkably low, based on repeated questions where either the orientation or the presentation order of a mass was changed. Various machine learning algorithms were explored to determine whether they can predict each observer's personalized selection using textural features. Many algorithms performed with accuracy that exceeded each observer's self-consistency rate, as determined using a cross-validation scheme. This accuracy was statistically significantly higher than would be expected by chance alone (two-tailed p-value ranged between 0.001 and 0.01 for all five personalized models). The study confirmed that human perception subjectivity should be taken into account when developing CBIR-based medical applications.

This research found that older individuals with more positive self-perceptions of aging, measured up to 23 years earlier, lived 7.5 years longer than those with less positive self-perceptions of aging. This advantage remained after age, gender, socioeconomic status, loneliness, and functional health were included as covariates. It was also found that this effect is partially mediated by will to live. The sample consisted of 660 individuals aged 50 and older who participated in a community-based survey, the Ohio Longitudinal Study of Aging and Retirement (OLSAR). By matching the OLSAR to mortality data recently obtained from the National Death Index, the authors were able to conduct survival analyses. The findings suggest that the self-perceptions of stigmatized groups can influence longevity.

Horswill, Mark S; Garth, Megan; Hill, Andrew; Watson, Marcus O

2017-04-01

Drivers' hazard perception ability has been found to predict crash risk, and novice drivers appear to be particularly poor at this skill. This competency appears to develop only slowly with experience, and this could partially be a result of poor quality performance feedback. We report an experiment in which we provided high-quality artificial feedback on individual drivers' performance in a validated video-based hazard perception test via either: (1) a graph-based comparison of hazard perception response times between the test-taker, the average driver, and an expert driver; (2) a video-based comparison between the same groups; or (3) both. All three types of feedback resulted in both an improvement in hazard perception performance and a reduction in self-rated hazard perception skill, compared with a no-feedback control group. Video-based and graph-based feedback combined resulted in a greater improvement in hazard perception performance than either of the individual components, which did not differ from one another. All three types of feedback eliminated participants' self-enhancement bias for hazard perception skill. Participants judged both interventions involving video feedback to be significantly more likely to improve their real-world driving than the no feedback control group. While all three forms of feedback had some value, the combined video and graph feedback intervention appeared to be the most effective across all outcome measures. Copyright © 2017 Elsevier Ltd.

Cross-sectional validation of the Aging Perceptions Questionnaire: a multidimensional instrument for assessing self-perceptions of aging.

LENUS (Irish Health Repository)

Barker, Maja

2007-01-01

BACKGROUND: Self-perceptions of aging have been implicated as independent predictors of functional disability and mortality in older adults. In spite of this, research on self-perceptions of aging is limited. One reason for this is the absence of adequate measures. Specifically, there is a need to develop a measure that is theoretically-derived, has good psychometric properties, and is multidimensional in nature. The present research seeks to address this need by adopting the Self-Regulation Model as a framework and using it to develop a comprehensive, multi-dimensional instrument for assessing self-perceptions of aging. This study describes the validation of this newly-developed instrument, the Aging Perceptions Questionnaire (APQ). METHODS: Participants were 2,033 randomly selected community-dwelling older (+65 yrs) Irish adults who completed the APQ alongside measures of physical and psychological health. The APQ assesses self-perceptions of aging along eight distinct domains or subscales; seven of these examine views about own aging, these are: timeline chronic, timeline cyclical, consequences positive, consequences negative, control positive, control negative, and emotional representations; the eighth domain is the identity domain and this examines the experience of health-related changes. RESULTS: Mokken scale analysis showed that the majority of items within the views about aging subscales were strongly scalable. Confirmatory factor analysis also indicated that the model provided a good fit for the data. Overall, subscales had good internal reliabilities. Hierarchical linear regression was conducted to investigate the independent contribution of APQ subscales to physical and psychological health and in doing so determine the construct validity of the APQ. Results showed that self-perceptions of aging were independently related to physical and psychological health. Mediation testing also supported a role for self-perceptions of aging as partial mediators in

To verify the frequency of swallowing complaints in patients with benign nonsurgical thyroid disease and compare the self-perception of swallowing disorder intensity between different types of thyroid disease. The study sample comprised 39 women aged 19-58 years (38.54 ± 10.74) with hypothyroidism (n=22; 56.4%) or thyroid nodules (n=17; 43.6%). Presence and type of swallowing complaint and self-perception of swallowing disorder intensity were investigated by means of self-ratings recorded on a 100-millimeter visual analog scale. The data were analyzed by descriptive measures and the Mann-Whitney nonparametric test was used to compare the self-perception of swallowing disorder intensity between both clinical diagnoses of thyroid disease. The level of 5% was adopted for statistical significance. Twenty-six (66.7%) individuals reported the following swallowing complaints: pharyngolaryngeal stasis sensation (37.15%), chocking (34.29%), and odynophagia (28.57%). The mean value of self-perception of swallowing disorder intensity by the visual analog scale was 59.35 (± 27.38) millimeters. No difference in self-perception was reported between the clinical diagnoses of thyroid disease. In this sample, swallowing complaint was frequently observed in patients with benign nonsurgical thyroid disease. Moderate self-perception of swallowing disorder intensity was reported regardless of the clinical diagnosis of thyroid disease.

Regular self-weighing, which in this article is defined as weighing oneself regularly over a period of time (e.g., daily, weekly), is recommended as a weight loss strategy. However, the published literature lacks a review of the recent evidence provided by prospective, longitudinal studies. Moreover, no paper has reviewed the psychological effects of self-weighing. Therefore, the objective is to review the literature related to longitudinal associations between self-weighing and weight change as well as the psychological outcomes. Electronic literature searches in PubMed, Ovid PsycINFO, and Ebscohost CINAHL were conducted. Keywords included overweight, obesity, self-weighing, etc. Inclusion criteria included trials that were published in the past 25 years in English; participants were adults seeking weight loss treatment; results were based on longitudinal data. The results (N=17 studies) revealed that regular self-weighing was associated with more weight loss and not with adverse psychological outcomes (e.g., depression, anxiety). Findings demonstrated that the effect sizes of association between self-weighing and weight change varied across studies and also that the reported frequency of self-weighing varied across studies. The findings from prospective, longitudinal studies provide evidence that regular self-weighing has been associated with weight loss and not with negative psychological outcomes. © 2014 The Obesity Society.

Visual motion perception predicts driving hazard perception ability.

Lacherez, Philippe; Au, Sandra; Wood, Joanne M

2014-02-01

To examine the basis of previous findings of an association between indices of driving safety and visual motion sensitivity and to examine whether this association could be explained by low-level changes in visual function. A total of 36 visually normal participants (aged 19-80 years) completed a battery of standard vision tests including visual acuity, contrast sensitivity and automated visual fields and two tests of motion perception including sensitivity for movement of a drifting Gabor stimulus and sensitivity for displacement in a random dot kinematogram (Dmin ). Participants also completed a hazard perception test (HPT), which measured participants' response times to hazards embedded in video recordings of real-world driving, which has been shown to be linked to crash risk. Dmin for the random dot stimulus ranged from -0.88 to -0.12 log minutes of arc, and the minimum drift rate for the Gabor stimulus ranged from 0.01 to 0.35 cycles per second. Both measures of motion sensitivity significantly predicted response times on the HPT. In addition, while the relationship involving the HPT and motion sensitivity for the random dot kinematogram was partially explained by the other visual function measures, the relationship with sensitivity for detection of the drifting Gabor stimulus remained significant even after controlling for these variables. These findings suggest that motion perception plays an important role in the visual perception of driving-relevant hazards independent of other areas of visual function and should be further explored as a predictive test of driving safety. Future research should explore the causes of reduced motion perception to develop better interventions to improve road safety. © 2012 The Authors.

Self-other differences in H1N1 flu risk perception in a global context: a comparative study between the United States and China.

Science.gov (United States)

Han, Gang Kevin; Zhang, Jueman Mandy; Chu, Kejun Rebecca; Shen, Guolin

2014-01-01

Extending research on self-other differences in perception to a global health risk, this study compares U.S. and Chinese college students' perceived H1N1 flu risk at four levels: personal, group, societal, and global. It also examines how personal experience, interpersonal communication, traditional and Internet-based media, and self-efficacy affect perception at four levels, as well as the self-other differences between the personal level and each of the other three levels. An online survey in both countries reveals an "ascending pattern," showing higher perceived risk for others than for selves. Chinese respondents perceive higher risk than U.S. respondents at all levels. Interpersonal communication predicts risk perception at four levels in the United States and at the group and societal levels in China. New media exposure exerts influence on all but the group level in China, while social networking sites (SNS) exposure predicts group- and societal-level risk perception in the United States. The overall attention paid to H1N1 information in the media affects all levels in both countries. Interaction between media exposure and attention is influential at all levels in the United States. Self-efficacy is negatively associated with risk perception in China except at the global level. Attention to media in the United States, and SNS exposure in China, explain the self-other differences in three comparisons, along with self-efficacy, which decreases the self-other gap in the United States while increasing the gap in China.

Positively Biased Self-Perceptions of Peer Acceptance and Subtypes of Aggression in Children

There is a growing body of research linking children’s positively biased self-perceptions with higher levels of aggression. This study extended this area of research by examining prospective associations of positively biased self-perceptions of peer acceptance with overt and relational aggression. In addition, moderating effects of peer rejection were examined to test the “disputed overestimation hypothesis,” which posits that the link between bias and aggression is limited to children who are rejected by their peers. Using a two-wave longitudinal design, measures of peer-rated and self-perceived peer acceptance and peer-rated overt and relational aggression were obtained for 712 children in 3rd through 5th grades (386 girls and 326 boys). Positively biased perceptions led to increases in relational, but not overt, aggression. This pattern was observed even when the effects of gender, race, peer rejection, and overt aggression on relational aggression were controlled. Contrary to the disputed overestimation hypothesis, the prospective associations between bias and aggression did not vary as a function of children’s peer rejection status, thus supporting the view that positive bias predicts future aggressive behavior, regardless of social status. The results are discussed in terms of the comparability with previous findings and practical implications. PMID:26423823

To identify the relationship and behaviour of the variables of self-control, self-efficacy and locus control in weight regulation of obese, overweight and normal weight adults. Transversal study undertaken in the Health Centre of El Coto (Gijón) from 1st April to 30th July 2015. Subjects between 18-65 years of age with a body mass index recording within the last two years. serious medical illness, eating disorders or pregnant women. Behavioural variables: self-regulation of body weight (Inventory of self-control of body weight), perceived self-efficacy in weight regulation (Inventory of perceived self-efficacy in weight regulation) and locus control in weight regulation (Inventory of locus control in weight regulation). Anthropometric variables: weight (kg) and height (m), body mass index. One hundred and six participants were included: 32 were obese, 28 overweight and 46 normal weight. Significant differences were found between the 3 study groups for total scale of self-efficacy (F=61.77; pcontrol (F=13.92; p=.019), other weighty influences of locus control (F=9.21; pcontrol (F=3.50; p=.011). The relationship between body mass index and behavioural variables of self-efficacy, self-regulation and locus control, suggests the need for healthcare professionals to include psychological factors of behaviour in any preventive action and intervention directed at weight control.

Purpose To examine accuracy of children’s, their guardians’, and health care professionals’ (HCPs’) perceptions of child overweight and obesity, the degree of agreement between their perceptions, and relationships with weight loss attempts among overweight or obese children. Design Cross-sectional study using 2005–2010 National Health and Nutrition Examination Survey. Setting United States. Subjects Out of 4691 children and adolescents, ages 8 to 15 years, 16.4% were overweight (body mass index [BMI] percentiles 85–94.99) and 19.3% were obese (BMI percentiles ≥95). Measures Age and sex-specific BMI percentiles; responses of adult proxies (guardians) on whether they considered their child overweight and whether an HCP had ever told them that their child was overweight; responses of children and adolescents on their self-perceived weight status and whether they were trying to lose weight; children’s and guardians’ socio-demographic characteristics. Analysis Weighted percentages; sensitivities and Cohen’s kappas; adjusted prevalence ratios. Results Children, their guardians, and HCPs underestimated child’s actual overweight or obesity status. Little agreement existed between overweight or obese children, their parents, and HCPs on whether these children were overweight or obese. Overweight and obese children perceived as such by themselves, their guardians, and HCPs were 88% and 32%, respectively, more likely to attempt weight loss based on multivariable analyses. Conclusion Accurate and shared perceptions of adiposity in children and adolescents between children themselves, their guardians, and HCPs are positively associated with weight loss attempts among overweight or obese children in the United States.

Wilski, M; Tasiemski, T

2016-05-01

Self-management of a disease is considered one of the most important factors affecting the treatment outcome. The research on the correlates of self-management in multiple sclerosis (MS) is limited. The aim of this study was to determine if personal factors, such as illness perception, treatment beliefs, self-esteem and self-efficacy, are correlates of self-management in MS. This cross-sectional study included 210 patients with MS who completed Multiple Sclerosis Self-Management Scale - Revised, Brief Illness Perception Questionnaire, Treatment Beliefs Scale, Rosenberg Self-Esteem Scale, and Generalized Self-Efficacy Scale. The patients were recruited from a MS rehabilitation clinic. Demographic data and illness-related problems of the study participants were collected with a self-report survey. Correlation and regression analyses were performed to determine associations between variables. Four factors: age at the time of the study (β = 0.14, P = 0.032), timeline (β = 0.16, P = 0.018), treatment control (β = 0.17, P = 0.022), and general self-efficacy (β = 0.19, P = 0.014) turned out to be the significant correlates of self-management in MS. The model including these variables explained 25% of variance in self-management in MS. Personal factors, such as general self-efficacy, perception of treatment control and realistic MS timeline perspective, are more salient correlates of self-management in MS than the objective clinical variables, such as the severity, type, and duration of MS. © 2015 John Wiley & Sons A/S.

2018-02-01

While the trajectory of self-esteem from adolescence to adulthood varies from person to person, little research has examined how differences in early developmental processes might affect these pathways. This study examined how early motor skill development interacted with preterm birth status to predict self-esteem from adolescence through the early 30s. We addressed this using the oldest known, prospectively followed cohort of extremely low birth weight (self-report, and self-esteem was reported during three follow-up periods (age 12-16, age 22-26, and age 29-36). We found that birth weight status moderated the association between early motor skills and self-esteem. Stable over three decades, the self-esteem of normal birth weight participants was sensitive to early motor skills such that those with poorer motor functioning manifested lower self-esteem, while those with better motor skills manifested higher self-esteem. Conversely, differences in motor skill development did not affect the self-esteem from adolescence to adulthood in individuals born at extremely low birth weight. Early motor skill development may exert differential effects on self-esteem, depending on whether one is born at term or prematurely.

Weight status and the perception of body image in men

Full Text Available Rick M Gardner Department of Psychology, University of Colorado Denver, Denver, CO, USA Abstract: Understanding the role of body size in relation to the accuracy of body image perception in men is an important topic because of the implications for avoiding and treating obesity, and it may serve as a potential diagnostic criterion for eating disorders. The early research on this topic produced mixed findings. About one-half of the early studies showed that obese men overestimated their body size, with the remaining half providing accurate estimates. Later, improvements in research technology and methodology provided a clearer indication of the role of weight status in body image perception. Research in our laboratory has also produced diverse findings, including that obese subjects sometimes overestimate their body size. However, when examining our findings across several studies, obese subjects had about the same level of accuracy in estimating their body size as normal-weight subjects. Studies in our laboratory also permitted the separation of sensory and nonsensory factors in body image perception. In all but one instance, no differences were found overall between the ability of obese and normal-weight subjects to detect overall changes in body size. Importantly, however, obese subjects are better at detecting changes in their body size when the image is distorted to be too thin as compared to too wide. Both obese and normal-weight men require about a 3%–7% change in the width of their body size in order to detect the change reliably. Correlations between a range of body mass index values and body size estimation accuracy indicated no relationship between these variables. Numerous studies in other laboratories asked men to place their body size into discrete categorizes, ranging from thin to obese. Researchers found that overweight and obese men underestimate their weight status, and that men are less accurate in their categorizations than

To analyze the relationship between self-concept, aerobic capacity and weight status in schoolchildren. Relational descriptive design in which was assessed the weight status and aerobic capacity of 256 schoolchildren among 8-11 years. Aerobic capacity (low vs high) and the body mass index (normal-weight vs overweight-obesity) were categorized using standard criteria. The self-concept was assessed through the Piers Harris self-concept scale for children. Schoolchildren with normal-weight and high fitness level showed better levels of conductual self-concept (P=.030), physical (Pself-concept (P=.002). The schoolchildren with normal-weight show higher levels of conductual self-concpt (P=.016), intellectual (P=.050), physical (Pself-concept (P=.001). The schoolchildren with a higher fitness level showed better conductual self-concept (P=.024), physical (P=.004), lack of anxiety (P=.011), social (P=.024), and global (P=.003). The results of the study strengthen the importance to transmit to the educative community the knowledge of the relationship between the variables analyzed aiming to improve the schoolchildren self-concept.

BMI (Body-mass index) was used to evaluate the body weight status. Subjects were classified into normal weight, overweight and obesity according to international standards. The six dimensions of self-concept (intellectual, behavioral, physical, lack of anxiety, social and life satisfaction) were assessed using the Piers-Harris Self-Concept Scale. The results showed significant associations between BMI and intellectual self-concept, life satisfaction, global self-concept and physical self. Subjects categorized as overweight or obese were those who showed lower scores on the self-concept scale. Interventions focused on improving the body weight status are needed in order to achieve better self-concept levels and health among young people. Copyright AULA MEDICA EDICIONES 2014.

To describe the relationships between non-alcoholic fatty-liver disease (NAFLD) patient's disease consequences and treatment perceptions, self-efficacy, and healthy lifestyle maintenance. A cross-sectional study among 146 ultrasound diagnosed NAFLD patients who visited the fatty liver clinic at the Tel-Aviv Medical Center. Eighty-seven of these individuals, participated in a clinical trial of physical activity and underwent fasting blood tests, analyzed at the same lab. Exclusion criteria included positivity for serum HBsAg or anti-HCV antibodies; fatty liver suspected to be secondary to hepatotoxic drugs; excessive alcohol consumption (≥ 30 g/d in men or ≥ 20 g/d in women) and positive markers of genetic or immune-mediated liver diseases. Patients were asked to complete a self-report structured questionnaire, assembled by the Israeli Center for Disease Control. Nutrition habits were measured using six yes/no questions (0 = no, 1 = yes) adopted from the national survey questionnaire. Participants in the clinical trial completed a detailed semi-quantitative food frequency questionnaire (FFQ) reporting their habitual nutritional intake during the past year. Self-efficacy was assessed by the Self-Efficacy Scale questionnaire, emotional representation, degree of illness understanding, timeline perception, treatment perception and symptoms were measured by the Brief Illness Perception questionnaire. Illness consequences were measured by the Personal Models of Diabetes Interview questionnaire. A path analysis was performed to describe the interrelationships between the patients' illness perceptions, and assess the extent to which the data fit a prediction of nutritional habits. The study sample included 54.1% men, with a mean age of 47.76 ± 11.68 years (range: 20-60) and mean body mass index of 31.56 ± 4.6. The average perceived nutrition habits score was 4.73 ± 1.45 on a scale between 0-6, where 6 represents the healthiest eating habits. Most of the study

Full Text Available “Biased self-perception,” the tendency to perceive one’s social performance as more negative than observers do, is characteristic of socially anxious individuals. Self-attention processes are hypothesised to underlie biased self-perception, however, different models emphasise different aspects of self-attention, with attention to the public aspects of the self being prominent. The current study aimed to investigate the relative contribution of two types of dispositional self-attention; public- and private self-consciousness to biased self-perception in a high (n = 48 versus a low (n = 48 social anxiety group undergoing an interaction task. The main finding was that private self-consciousness explained substantial and unique variance in biased negative self-perception in individuals with high social anxiety, while public self-consciousness did not. This relationship was independent of increments in state anxiety. Private self-consciousness appeared to have a specific association with bias related to overestimation of negative social performance rather than underestimation of positive social performance. The implication of this finding is that current treatment models of Social anxiety disorder might include broader aspects of self-focused attention, especially in the context of formulating self-evaluation biases.

We compared participants' self-perception of their weight with the World Health Organisation (WHO) definition for BMI categories among undergraduate university students undertaking health related academic programmes in Ghana. Also, we investigated factors associated to the underestimation of weight status in this sample. This cross-sectional study was conducted among a sample of 368 undergraduate students. Anthropometric measurements of weight and height were measured with appropriate tools and computed into Body Mass Index (BMI) categorised based on WHO classifications. Waist and hip circumferences were also measured appropriately. Participants' self-perception of weight status was assessed by the question: How do you perceive your weight? (a) Underweight, (b) normal weight, (c) overweight, and (d) obese. The BMI-measured weight status was compared to the self-perceived weight status by cross-tabulation, Kappa statistics of agreement and χ(2) for trend analysis. Factors associated with misperception of weight status was measured using univariate and multivariable analysis. Thirteen percent (n=48) of the participants were overweight/obesity (BMI) and 31.5% had central obesity. Overall, 20.6% of the participants misperceived their weight status in which 78.9% of them underestimated it. Among overweight/obese participants, 41.7% self-perceived themselves accurately. Whereas 10.6% of normal weight participants underestimated their weight status, over half (58.3%) of overweight/obese participants did so. Factors that were associated with underestimation of weight status were having overweight/obesity (BMI) and central obesity. Underestimation of weight status was frequent. Health professionals and related government agencies should develop intervention programmes to empower young people to have accurate weight status perception.

The present study sought to replicate the finding of Wildes and Marcus, Behav Res Ther, 50, 266-274, 2012 that higher levels of weight suppression at pretreatment predict greater total weight gain, faster rate of weight gain, and bulimic symptoms amongst patients admitted with anorexia nervosa. Participants were 56 women with anorexia nervosa diagnosed by using strict or lenient weight criteria, who were participating in a randomized controlled psychotherapy trial (McIntosh et al., Am J Psychiatry, 162, 741-747, 2005). Thirty-five women completed outpatient treatment and post-treatment assessment. Weight suppression was the discrepancy between highest lifetime weight at adult height and weight at pretreatment assessment. Outcome variables were total weight gain, rate of weight gain, and bulimic symptoms in the month prior to post-treatment assessment [assessed using the Eating Disorders Examination (Fairburn et al., Binge-Eating: Nature, Assessment and Treatment. New York: Guilford, 1993)]. Weight suppression was positively associated with total weight gain and rate of weight gain over treatment. Regression models showed that this association could not be explained by covariates (age at onset of anorexia nervosa and treatment modality). Weight suppression was not significantly associated with bulimic symptoms in the month prior to post-treatment assessment, regardless of whether bulimic symptoms were examined as continuous or dichotomous variables. The present study reinforces the previous finding that weight suppression predicts total weight gain and rate of weight gain amongst patients being treated for anorexia nervosa. Methodological issues may explain the failure of the present study to find that weight suppression predicts bulimic symptoms. Weight suppression at pretreatment for anorexia nervosa should be assessed routinely and may inform treatment planning. © 2015 Wiley Periodicals, Inc.

To examine the relationship between self-perceptions of aging and acute medical events in chronically institutionalized middle-aged and older persons with schizophrenia. Participants were 83 persons with schizophrenia (30% women; mean age = 58.48, SD = 8.14) residing in a long-stay care home, who were without organic mental disorders, mental retardation, serious audiovisual impairment, and serious cognitive and physical impairment. They received assessments in body mass index, functional health, and global mental status, and responded to measures of self-perception of aging at baseline. Acute events that required medical attention were recorded for the next 3 months. 8% of the participants had acute medical events. Bivariate analysis suggested that number of comorbid medical conditions, mobility, Mini-Mental State Examination, and negative self-perception of aging were predictive of acute medical events. However, multivariate analysis (logistic regression) showed that only mobility (OR = 0.78, p = 0.04) and negative self-perception of aging (OR = 3.38, p = 0.02) had independent effects on acute medical events, with the latter being the stronger predictor. Positive aging self-perception, body mass index, and smoking were unrelated to medical events. Physical vulnerabilities may not be sufficient to explain the development of acute medical events in late-life schizophrenia. How individuals perceive their aging process, which is expected to regulate health behavior and help-seeking, may be an even more important factor. Further research should investigate whether such self-perceptions, which are probably rooted in stereotypes about aging socialized early in life, are modifiable in this population.

Parental perceptions of their children's weight status may limit their willingness to participate in or acknowledge the importance of early interventions to prevent childhood obesity. This study aimed to examine potential differences in Hispanic mothers' and fathers' perceptions of childhood obesity, lifestyle behaviors and communication preferences to inform the development of culturally appropriate childhood obesity interventions. A qualitative study using focus groups was conducted. Groups (one for mothers and one for fathers) were composed of Hispanic parents (n = 12) with at least one girl and one boy (≤ 10 years old) who were patients at a pediatric clinic in Tennessee, USA. Thirteen major themes clustered into four categories were observed: (i) perceptions of childhood obesity/children's weight; (ii) parenting strategies related to children's dietary behaviors/physical activity; (iii) perceptions of what parents can do to prevent childhood obesity and (iv) parental suggestions for partnering with child care providers to address childhood obesity. Mothers appeared to be more concerned than fathers about their children's weight. Fathers expressed more concern about the girls' weight than boys'. Mothers were more likely than fathers to congratulate their children more often for healthy eating and physical activity. Parents collectively expressed a desire for child care providers (e.g. caregivers, teachers, medical professionals and food assistance programs coordinators) to have a caring attitude about their children, which might in turn serve as a motivating factor in talking about their children's weight. Parental perceptions of their children's weight and healthy lifestyle choices are of potential public health importance since they could affect parental participation in preventive interventions. © The Author 2016.

Action identity: evidence from self-recognition, prediction, and coordination.

Science.gov (United States)

Knoblich, Günther; Flach, Rüdiger

2003-12-01

Prior research suggests that the action system is responsible for creating an immediate sense of self by determining whether certain sensations and perceptions are the result of one's own actions. In addition, it is assumed that declarative, episodic, or autobiographical memories create a temporally extended sense of self or some form of identity. In the present article, we review recent evidence suggesting that action (procedural) knowledge also forms part of a person's identity, an action identity, so to speak. Experiments that addressed self-recognition of past actions, prediction, and coordination provide ample evidence for this assumption. The phenomena observed in these experiments can be explained by the assumption that observing an action results in the activation of action representations, the more so, when the action observed corresponds to the way in which the observer would produce it.

Underestimating body size hinders healthy behavior modification needed to prevent obesity. However, initiatives to improve body size misperceptions may have detrimental consequences on self-esteem and self-efficacy. Using sex-specific multiple mixed-effect logistic regression models, we examined the association of underestimating versus accurate body size perceptions with self-esteem and self-efficacy in a provincially representative sample of 5075 grade five school children. Body size perceptions were defined as the standardized difference between the body mass index (BMI, from measured height and weight) and self-perceived body size (Stunkard body rating scale). Self-esteem and self-efficacy for physical activity and healthy eating were self-reported. Most of overweight boys and girls (91% and 83%); and most of obese boys and girls (93% and 90%) underestimated body size. Underestimating weight was associated with greater self-efficacy for physical activity and healthy eating among normal-weight children (odds ratio: 1.9 and 1.6 for boys, 1.5 and 1.4 for girls) and greater self-esteem among overweight and obese children (odds ratio: 2.0 and 6.2 for boys, 2.0 and 3.4 for girls). Results highlight the importance of developing optimal intervention strategies as part of targeted obesity prevention efforts that de-emphasize the focus on body weight, while improving body size perceptions.

Full Text Available The aims of the current study were to explore possible gender differences in weight misperception, self-reported physical fitness, and dieting, and to analyze the relationship between these variables and others, such as self-esteem, body appreciation, general mental health, and eating- and body image-related variables among adolescents. In addition, the specific risk for eating disorders was examined, as well as the possible clusters with respect to the risk status. The sample comprised 655 students, 313 females and 342 males, aged 16.22 ± 4.58. Different scales of perceived overweight, self-reported physical fitness and dieting together with the Body Mass Index (BMI were considered along with instruments such as the International Physical Activity Questionnaire (IPAQ, General Health Questionnaire (GHQ-28, Self-Esteem Scale (SES, Body Appreciation Scale (BAS and Eating Disorders Inventory-2 (EDI-2. Since some gender differences were found with respect to these adolescent groups, it is necessary to design prevention programs that not only focus on traditional factors such as BMI or body image, but also on elements like weight perception, self-reported fitness and nutritional education.

Can illness perceptions predict lower heart rate variability following acute myocardial infarction?

Directory of Open Access Journals (Sweden)

Mary Princip

2016-11-01

Full Text Available Objective: Decreased heart rate variability (HRV has been reported to be a predictor of mortality after myocardial infarction (MI. Patients’ beliefs and perceptions concerning their illness may play a role in decreased HRV. This study investigated if illness perceptions predict HRV at three months following acute MI. Methods: 130 patients referred to a tertiary cardiology centre, were examined within 48 hours and three months following acute MI. At admission, patients’ cognitive representations of their MI were assessed using the German version of the self-rated Brief Illness Perception Questionnaire (Brief IPQ. At admission and after three months (follow-up, frequency and time domain measures of HRV were obtained from 5-min electrocardiogram (ECG recordings during stable supine resting. Results: Linear hierarchical regression showed that the Brief IPQ dimensions timeline (β coefficient = -0.29; p = .044, personal control (β = 0.47; p = .008 and illness understanding (β = 0.43; p = .014 were significant predictors of HRV, adjusted for age, gender, baseline HRV, diabetes, beta-blockers, left ventricular ejection fraction (LVEF, attendance of cardiac rehabilitation, and depressive symptoms. Conclusions: As patients’ negative perceptions of their illness are associated with lower HRV following acute MI, a brief illness perception questionnaire may help to identify patients who might benefit from a specific illness perceptions intervention.

While childhood behaviors such as aggression, social withdrawal and likeability have been linked to substance abuse outcomes in adolescence and adulthood, the mechanisms by which these variables relate are not yet well established. Self and peer perceptions of childhood behaviors in men and women were compared to assess the role of context in the prediction of drug and alcohol abuse and dependence. Participants (N=676) in an ongoing longitudinal project examining the relation between childhood behavior and adult mental health outcomes completed the Structured Clinical Interview for the DSM IV regarding their histories of substance abuse in mid-adulthood (mean age=34, SD=2). In women, higher levels of both self and peer reported aggression were associated with drug and alcohol abuse and dependence, and higher levels of peer reported aggression were associated with higher levels of alcohol abuse and dependence. As well, higher levels of self-perceived likeability were protective regarding substance abuse and dependence outcomes. In men, higher levels of peer perceived social withdrawal were protective regarding substance abuse and dependence outcomes. Findings support the comparison of self and peer perceptions of childhood behavior as a method of assessing the mechanisms by which childhood behaviors impact adult outcomes, and suggest the importance of gender in the relation between childhood behaviors and adult substance abuse and dependence.

Full Text Available This study aimed at investigating the impact of the quality of life perception on the self-esteem of physically active adults. A total of 63 male and female swimming practitioners (38.13 ± 11.72 were evaluated. A socio-demographic questionnaire, WHOQOL-Bref Scale, and the Rosenberg Self-Esteem Scale were used as tools. For data analysis the descriptive statistics, Kolmogorov-Smirnov Test, Mann-Whitney U Test, Spearman’s Rank Correlation Coefficient, and the Univariate Multiple Regression were used. No significant differences were found either for the quality of life or the self-esteem between sexes; there was a significant positive correlation (p < 0.05 among the physical (r = 0.37, psychological (r = 0.36 and environmental (r = 0.30 domains with self-esteem. The regression model explained 20% of the self-esteem variability, with moderate and significant pathways of the physical (β = 0.23 and psychological (β = 0.23 domains, whereas the environmental domain did not show a significant predictive relation (p = 0.988 with self-esteem. It is concluded that a higher quality of life perception may result in a higher self-esteem for physically active adults.

Subjective perceptions and perceived needs for dental care in a population can provide important information for policy-makers. This study aimed to assess self-perceived personal oral health status among the Saudi Arabia population who could be accessed through social media. A pre-tested questionnaire for completion online was designed to assess self-perceived oral health via 13 items in 4 domains with weighted scores from 1-3. The questionnaire was uploaded to the Internet and the link to it was made available through popular social networking sites in Saudi Arabia. With respondents recruited by snowball methods a total of 4618 people (57.2% males, 42.8% females) completed the questionnaire. The total mean score for the participants was 23.0 (SD 5.0) (scale range 13-39). Self-perceived oral health was rated as poor by 24.2% of respondents, average by 50.6% and good by 25.2%. Educational level, age and region but not sex were significantly associated with self-perceived oral health.

To identify which English and Spanish terms Latino parents consider motivating, as well as culturally and linguistically appropriate, for provider use during weight counseling of overweight and obese Latino youth. Latino parent perceptions of common Spanish and English terms for overweight were discussed with 54 parents in 6 focus groups (3 English, 3 Spanish). Atlas.ti software was used for qualitative analysis. An initial codebook was used to code passages for English and Spanish terminology separately. Subsequent changes to the coded passages and creation of new codes were made by team consensus. "Demasiado peso para su salud" (too much weight for his/her health) was the only phrase for excess weight that was consistently identified as motivating and inoffensive by Spanish-speaking parents. "Sobrepeso" (overweight), a commonly used term among health care providers, was motivating to some parents but offensive to others. English-speaking parents had mixed reactions to "unhealthy weight," "weight problem," and "overweight," finding them motivating, confusing, or insulting. Parents found "fat" "gordo" and "obese" "obeso" consistently offensive. Most participants found growth charts and the term "BMI" confusing. Parents consistently reported that providers could enhance motivation and avoid offending families by linking a child's weight to health risks, particularly diabetes. "Demasiado peso para su salud" (too much weight for his/her health) was motivating to many Spanish-speaking Latino parents. Among English-speaking Latino parents, no single English term emerged as motivating, well-understood, and inoffensive. Linking a child's excess weight with increased health risks was motivating and valuable to many parents regardless of language spoken. Copyright © 2015 Academic Pediatric Association.

Full Text Available Abstract Objectives This study seeks to determine whether perception of weight status among the overweight has changed with the increasing overweight/obesity prevalence. Methods The perception of weight status was compared between overweight participants (BMI between 25.0–29.9 kg/m2 from NHANES III (1988–1994 and overweight participants from NHANES 1999–2004. Perception of weight status was assessed by asking participants to classify their weight as about the right weight, underweight or overweight. Comparisons were made across age groups, genders, race/ethnicities and various income levels. Results Fewer overweight people during the NHANES 1999–2004 survey perceived themselves as overweight when compared to overweight people during the NHANES III survey. The change in distortion between the survey periods was greatest among persons with lower income, males and African-Americans. Conclusion The increase in overweight/obesity between the survey years (NHANES III and NHANES 1999–2004 has been accompanied with fewer overweight people perceiving themselves as overweight.

The role of semantic self-perceptions in temporal distance perceptions toward autobiographical events: the semantic congruence model.

Gebauer, Jochen E; Haddock, Geoffrey; Broemer, Philip; von Hecker, Ulrich

2013-11-01

Why do some autobiographical events feel as if they happened yesterday, whereas others feel like ancient history? Such temporal distance perceptions have surprisingly little to do with actual calendar time distance. Instead, psychologists have found that people typically perceive positive autobiographical events as overly recent, while perceiving negative events as overly distant. The origins of this temporal distance bias have been sought in self-enhancement strivings and mood congruence between autobiographical events and chronic mood. As such, past research exclusively focused on the evaluative features of autobiographical events, while neglecting semantic features. To close this gap, we introduce a semantic congruence model. Capitalizing on the Big Two self-perception dimensions, Study 1 showed that high semantic congruence between recalled autobiographical events and trait self-perceptions render the recalled events subjectively recent. Specifically, interpersonally warm (competent) individuals perceived autobiographical events reflecting warmth (competence) as relatively recent, but warm (competent) individuals did not perceive events reflecting competence (warmth) as relatively recent. Study 2 found that conscious perceptions of congruence mediate these effects. Studies 3 and 4 showed that neither mood congruence nor self-enhancement account for these results. Study 5 extended the results from the Big Two to the Big Five self-perception dimensions, while affirming the independence of the semantic congruence model from evaluative influences.

This study focuses on body weight motivation based on self-determination theory. The impact of body weight motivation on longitudinal changes in food choices, recreational physical activity and body mass index was explored. A sample of adults (N = 2917, 47% men), randomly selected from the telephone book, completed a questionnaire in two consecutive years (2012, 2013), self-reporting food choices, recreational physical activity and body weight motivation. Types of body weight motivation at T1 (autonomous regulation, introjected regulation, and external regulation) were tested with regard to their predictive potential for changes in food choices, recreational physical activity and body mass index (BMI). Autonomous motivation predicted improvements in food choices and long-term adherence to vigorous recreational physical activity in both genders. Introjected motivation predicted long-term adherence to vigorous recreational physical activity only in women. External motivation predicted negative changes in food choices; however, the type of body weight motivation had no impact on BMI in overweight adults in the long term. Autonomous goal-setting regarding body weight seems to be substantial for healthy food choices and adherence to recreational physical activity.

To identify predictors of initial weight loss among women with abdominal obesity by using a path model. Successful weight loss in the initial stages of long-term weight management may promote weight loss maintenance. A longitudinal study design. Study participants were 75 women with abdominal obesity, who were enrolled in a 12-month Community-based Heart and Weight Management Trial and followed until a 6-month assessment. The Weight Efficacy Lifestyle, Exercise Self-Efficacy and Health Promoting Lifestyle Profile-II measured diet self-efficacy, exercise self-efficacy and health-promoting behaviour respectively. All endogenous and exogenous variables used in our path model were change variables from baseline to 6 months. Data were collected between May 2011-May 2012. Based on the path model, increases in both diet and exercise self-efficacy had significant effects on increases in health-promoting behaviour. Increases in diet self-efficacy had a significant indirect effect on initial weight loss via increases in health-promoting behaviour. Increases in health-promoting behaviour had a significant effect on initial weight loss. Among women with abdominal obesity, increased diet self-efficacy and health-promoting behaviour were predictors of initial weight loss. A mechanism by which increased diet self-efficacy predicts initial weight loss may be partially attributable to health-promoting behavioural change. However, more work is still needed to verify causality. Based on the current findings, intensive nursing strategies for increasing self-efficacy for weight control and health-promoting behaviour may be essential components for better weight loss in the initial stage of a weight management intervention. © 2015 John Wiley & Sons Ltd.

Investigating Flipped Learning: Student Self-Regulated Learning, Perceptions, and Achievement in an Introductory Biology Course

Sletten, Sarah Rae

2017-06-01

In flipped classrooms, lectures, which are normally delivered in-class, are assigned as homework in the form of videos, and assignments that were traditionally assigned as homework, are done as learning activities in class. It was hypothesized that the effectiveness of the flipped model hinges on a student's desire and ability to adopt a self-directed learning style. The purpose of this study was twofold; it aimed at examining the relationship between two variables—students' perceptions of the flipped model and their self-regulated learning (SRL) behaviors—and the impact that these variables have on achievement in a flipped class. For the study, 76 participants from a flipped introductory biology course were asked about their SRL strategy use and perceptions of the flipped model. SRL strategy use was measured using a modified version of the Motivated Strategies for Learning Questionnaire (MSLQ; Wolters et al. 2005), while the flipped perceptions survey was newly derived. Student letter grades were collected as a measure of achievement. Through regression analysis, it was found that students' perceptions of the flipped model positively predict students' use of several types of SRL strategies. However, the data did not indicate a relationship between student perceptions and achievement, neither directly nor indirectly, through SRL strategy use. Results suggest that flipped classrooms demonstrate their successes in the active learning sessions through constructivist teaching methods. Video lectures hold an important role in flipped classes, however, students may need to practice SRL skills to become more self-directed and effectively learn from them.

This work shows the development of self levelling mortars, using micro bubbles based on aluminium silicate with a density of 0.25 g/cm 3 . Mortars formulations are composed by 8 different components in order to achieve properties balance between fresh and solid state. The mean objective is development light weight mortars with high fluidity and compression strength using micro bubbles and some additives. Formulations were designed employing Taguchi DOE of 8 variables and 3 states. Result analysis according to Taguchi method lets indentify the preponderant effect of each variable on the cited properties. Several formulations reached fluidity higher than 250%, with compression strength around 100 kg/cm 2 and a low volumetric weigh. Obtained volumetric weights are 20% less than commercial self levelling mortars weight. Finally some relations are presented such: as relation water/cement with fluidity, and micro bubble content versus mortars volumetric weight, and finally compression strength versus the volumetric weight of mortars

Distancing from experienced self: how global-versus-local perception affects estimation of psychological distance.

Liberman, Nira; Förster, Jens

2009-08-01

In 4 studies, the authors examined the prediction derived from construal level theory (CLT) that higher level of perceptual construal would enhance estimated egocentric psychological distance. The authors primed participants with global perception, local perception, or both (the control condition). Relative to the control condition, global processing made participants estimate larger psychological distances in time (Study 1), space (Study 2), social distance (Study 3), and hypotheticality (Study 4). Local processing had the opposite effect. Consistent with CLT, all studies show that the effect of global-versus-local processing did emerge when participants estimated egocentric distances, which are distances from the experienced self in the here and now, but did not emerge with temporal distances not from now (Study 1), spatial distances not from here (Study 2), social distances not from the self (Study 3), or hypothetical events that did not involve altering an experienced reality (Study 4).

Full Text Available Introduction: Prison is societal implementer unit which accommodate care and develop the delinquent children. It was recorded that 57% of children at Blitar Child Prison undergo some self concept problems such as low self esteem. This was caused by some factors such as society’s stigmatization toward criminals, development pattern and education, and less support from family. If the self esteem problem is not being overcome soon, the children may  fell useless, disable to control their self and recrime when they are back to society. The objective of this study was to analyze the influence of  GAT (Group Activity Therapy perception stimulation in increasing the children  self esteem at prison. Method:  A quasy experimental pre post control design was used in this study. Samples were recruited by using total sampling and there were 22 samples as on inclusion criteria. The independent variable was GAT perception stimulation and the dependent variable was increasing self esteem of these childen. Data were collected by using questionnare and analyzed by using Wilcoxon Signed Ranks Test and Mann Whitney U Test with the significance level α≤0.05.Result:  The result showed that controlled group has significance level was p=0.654, it is mean there was no self esteem change before and after GAT perception stimulation was given. Whereas treatment group has significance level was p=0.001, it revealed that  there was self esteem change before and after GAT perception stimulation was given. The result of Mann Whitney U Test showed p=0.000 which means was accepted. Discussion: It can be concluded that perception stimulation can increase the children self esteem at prison. Further studies are recommended to study the effect of GAT perception stimulation modified by skill therapy in increasing children self esteem in prison.

The effects of acculturation, body perception, and health behaviors on weight status among Vietnamese American students in Houston, Texas were examined for our research. A survey was mailed to 600 randomly selected Vietnamese American students at one university, and 261 complete surveys (response rate, 43.5%) were used for final analyses. Respondents were classified as overweight or normal weight based on the World Health Organization recommended overweight cutoff for Asians (BMI of 23 kg/m(2)). About 32% of respondents were overweight. Men, undergraduate students, and those with an acceptable body perception were more likely to be overweight. Nativity and its interaction with length of US residence were significant predictors of weight status after controlling for other variables. Foreign-born respondents were less likely to be overweight than US-born respondents, but the risk of being overweight with increasing years of US residence was much greater for the foreign-born than for the US-born. The results suggest the need for culturally tailored overweight and obesity prevention programs for Vietnamese Americans.

Parents' Perceptions of Their Children as Overweight and Children's Weight Concerns and Weight Gain.

Robinson, Eric; Sutin, Angelina R

2017-03-01

The global prevalence of childhood obesity is alarmingly high. Parents' identification of their children as overweight is thought to be an important prerequisite to tackling childhood obesity, but recent findings suggest that such parental identification is counterintuitively associated with increased weight gain during childhood. One possibility is that parental identification of their child as being overweight results in that child viewing his or her body size negatively and attempting to lose weight, which eventually results in weight gain. We used data from two longitudinal cohort studies to examine the relation between children's weight gain and their parents' identification of them as being overweight. Across both studies, children whose parents perceive them to be overweight are more likely to view their body size negatively and are more likely than their peers to be actively trying to lose weight. These child-reported outcomes explained part of the counterintuitive association between parents' perceptions of their children as being overweight and the children's subsequent weight. We propose that the stigma attached to being recognized and labeled as "overweight" may partly explain these findings.

Being overweight and having negative self-perceptions (body dissatisfaction) can have problematic consequences for adolescents physically, socially, and psychologically. Understanding associations between weight, self-perceptions, and peer experiences across ethnicities is particularly important given recent increases in obesity among ethnic minorities. The current study aimed to address these issues by examining Body Mass Index (BMI) z-scores and body dissatisfaction predicting change in general self-worth over time via peer victimization experiences in a diverse sample of 236 youth (ages 10-16 years). Body dissatisfaction predicted decreases in self-worth over time even after controlling for BMI z-score. BMI z-scores predicted decreases in self-worth over time only for white adolescents, whereas body dissatisfaction directly predicted decreases in self-worth for African American youth and indirectly via peer victimization for white youth. Associations were also considered by gender. Implications for intervention efforts for both white and African American adolescents are discussed.

Considering Attachment and Partner Perceptions in the Prediction of Physical and Emotional Sexual Satisfaction.

Øverup, Camilla S; Smith, C Veronica

2017-01-01

Attachment theory provides a framework for understanding sexual satisfaction; in general, research suggests that attachment anxiety and avoidance are associated with decreased sexual satisfaction. Given their different working models of self and other, perceptions of the partner's level of satisfaction might differentially influence people's own perceptions of satisfaction based on their attachment avoidance and anxiety. To examine the predictive value of attachment anxiety and avoidance and perceptions of partner satisfaction in predicting physical and emotional satisfaction after sexual interactions in two studies. Participants (study 1, n = 52; study 2, n = 144) completed a one-time survey containing a measurement of attachment and then reported on their physical and emotional sexual satisfaction after each sexual interaction over the course of 2 to 3 weeks. The Experiences in Close Relationships Scale-Revised was completed during the one-time survey, and ratings of personal physical and emotional sexual satisfaction (studies 1 and 2) and perceptions of partner's physical and emotional satisfaction were completed after sexual interactions (study 2). Greater attachment avoidance was associated with lesser physical and emotional satisfaction. Moreover, when perceiving the partner to be emotionally satisfied, people with more attachment avoidance reported less emotional satisfaction for themselves. For greater attachment anxiety, greater perceived partner satisfaction (physical and emotional) predicted greater personal satisfaction of the two types. The findings support attachment theory as a valuable lens through which to study sexual satisfaction. Moreover, the results suggest that it is important to consider perceptions of partner sexual satisfaction in understanding the sexual satisfaction of people who demonstrate attachment anxiety and avoidance.

Phillips, Ceib; Beal, Kimberly N Edwards

2009-01-01

To examine, in adolescents with mild to moderate malocclusion, the relationship between self-concept and demographic characteristics, a clinical assessment of malocclusion, self-perception of malocclusion, and self-perception of facial attractiveness. Fifty-nine consecutive patients ages 9 to 15 years scheduled for initial records in a graduate orthodontic clinic consented to participate. Each subject independently completed the Multidimensional Self-Concept Scale (MSCS), the Facial Image Scale, and the Index of Treatment Need-Aesthetic Component (IOTN-AC). Peer Assessment Rating (PAR) scores were obtained from the patients' diagnostic dental casts. Forward multiple-regression analysis with a backward overlook was used to analyze the effect of the demographic, clinical, and self-perception measures on each of the six self-concept (MSCS) domains. Self-perception of the dentofacial region was the only statistically significant predictor (P self-perception of the dentofacial region were statistically significant predictors (P < .05) of Social Self-Concept. The self-perceived level of the attractiveness or "positive" feelings toward the dentofacial region is more strongly related to self-concept than the severity of the malocclusion as indicated by the PAR score or by the adolescent's perception of their malocclusion.

Haptic perception accuracy depending on self-produced movement.

Park, Chulwook; Kim, Seonjin

2014-01-01

This study measured whether self-produced movement influences haptic perception ability (experiment 1) as well as the factors associated with levels of influence (experiment 2) in racket sports. For experiment 1, the haptic perception accuracy levels of five male table tennis experts and five male novices were examined under two different conditions (no movement vs. movement). For experiment 2, the haptic afferent subsystems of five male table tennis experts and five male novices were investigated in only the self-produced movement-coupled condition. Inferential statistics (ANOVA, t-test) and custom-made devices (shock & vibration sensor, Qualisys Track Manager) of the data were used to determine the haptic perception accuracy (experiment 1, experiment 2) and its association with expertise. The results of this research show that expert-level players acquire higher accuracy with less variability (racket vibration and angle) than novice-level players, especially in their self-produced movement coupled performances. The important finding from this result is that, in terms of accuracy, the skill-associated differences were enlarged during self-produced movement. To explain the origin of this difference between experts and novices, the functional variability of haptic afferent subsystems can serve as a reference. These two factors (self-produced accuracy and the variability of haptic features) as investigated in this study would be useful criteria for educators in racket sports and suggest a broader hypothesis for further research into the effects of the haptic accuracy related to variability.

Exclusive breastfeeding reduces infant infectious disease. Losing > or =10% birth weight may lead to formula use. The predictive value of first-day weight loss for subsequent weight loss has not been studied. The objective of the present study was to evaluate the relationship between weight loss at or =10%. For 1,049 infants, we extracted gestational age, gender, delivery method, feeding type, and weights from medical records. Weight nadir was defined as the lowest weight recorded during birth hospitalization. We used multivariate logistic regression to assess the effect of first-day weight loss on subsequent in-hospital weight loss. Mean in-hospital weight nadir was 6.0 +/- 2.6%, and mean age at in-hospital weight nadir was 38.7 +/- 18.5 hours. While in the hospital 6.4% of infants lost > or =10% of birth weight. Infants losing > or =4.5% birth weight at or =10% (adjusted odds ratio 3.57 [1.75, 7.28]). In this cohort, 798 (76.1%) infants did not have documented weight gain while in the hospital. Early weight loss predicts higher risk of > or =10% in-hospital weight loss. Infants with high first-day weight loss could be targeted for further research into improved interventions to promote breastfeeding.

On the Role of Crossmodal Prediction in Audiovisual Emotion Perception

2013-07-01

Full Text Available Humans rely on multiple sensory modalities to determine the emotional state of others. In fact, such multisensory perception may be one of the mechanisms explaining the ease and efficiency by which others’ emotions are recognized. But how and when exactly do the different modalities interact? One aspect in multisensory perception that has received increasing interest in recent years is the concept of crossmodal prediction. In emotion perception, as in most other settings, visual information precedes the auditory one. Thereby, leading in visual information can facilitate subsequent auditory processing. While this mechanism has often been described in audiovisual speech perception, it has not been addressed so far in audiovisual emotion perception. Based on the current state of the art in (a crossmodal prediction and (b multisensory emotion perception research, we propose that it is essential to consider the former in order to fully understand the latter. Focusing on electroencephalographic (EEG and magnetoencephalographic (MEG studies, we provide a brief overview of the current research in both fields. In discussing these findings, we suggest that emotional visual information may allow for a more reliable prediction of auditory information compared to non-emotional visual information. In support of this hypothesis, we present a re-analysis of a previous data set that shows an inverse correlation between the N1 response in the EEG and the duration of visual emotional but not non-emotional information. If the assumption that emotional content allows for more reliable predictions can be corroborated in future studies, crossmodal prediction is a crucial factor in our understanding of multisensory emotion perception.

Weight loss and maintenance goals are highly prevalent in many affluent societies, but many weight regulators are not successful in the long term. Research started to reveal psychological mechanisms that help successful weight regulators in being successful. In the present study, we tested the assumption that these mechanisms facilitate successful self-regulation particularly under conditions of self-regulatory depletion. Participants exerted or did not exert self-control in a first task before engaging in a taste test of a tempting but unhealthy food. Participants who had initially exerted self-control ate more than participants in the control condition. This effect was reduced in self-perceived successful weight regulators as compared to perceived unsuccessful self-regulators. A reduced susceptibility to self-regulatory depletion may be an important contributor to long-term weight regulation success in successful weight regulators. Copyright © 2014 Elsevier Ltd.

Attitudes to weight and weight management in the early teenage years: a qualitative study of parental perceptions and views.

Wills, Wendy J; Lawton, Julia

2015-10-01

As most young teenagers grow up in families, parents might be well situated to facilitate and support their weight management and thereby prevent or manage obesity prior to adulthood. This paper explores parents' perceptions of, and views about, their teenage children's weight and the factors that influence parents' weight management strategies. We conducted two qualitative studies in Scotland, UK, involving in-depth interviews with the parents of overweight/obese and 'normal' weight 13-15 year olds (n = 69). Parents' concerns about their own weight provided useful context for understanding their attitudes or actions with regards to their teenage child. Some parents described their teenager's weight as being of concern to them, although puberty often introduced confusion about a child's weight status. Genetic explanations were very often put forward as a way of making sense of teenage weight or body size. Frustration about advising teenagers about weight management was expressed, and some parents worried about giving their growing child a 'problem' if they directly raised concerns about weight with them. Parents' views about their own weight as well as social and moral norms about labelling a teenager as overweight or as needing help with their weight could usefully inform patient-centred service development. Parent/teenage partnerships and supporting parents to create a healthy home in which teenagers can make healthier choices are suggestions for intervention development. The study highlights the importance of taking parents' perceptions into account when developing family-based interventions to address teenage overweight and obesity. © 2014 The Authors Health Expectations Published by John Wiley & Sons Ltd.

Weight status and the perception of body image in men

Gardner, Rick M

2014-01-01

Understanding the role of body size in relation to the accuracy of body image perception in men is an important topic because of the implications for avoiding and treating obesity, and it may serve as a potential diagnostic criterion for eating disorders. The early research on this topic produced mixed findings. About one-half of the early studies showed that obese men overestimated their body size, with the remaining half providing accurate estimates. Later, improvements in research technology and methodology provided a clearer indication of the role of weight status in body image perception. Research in our laboratory has also produced diverse findings, including that obese subjects sometimes overestimate their body size. However, when examining our findings across several studies, obese subjects had about the same level of accuracy in estimating their body size as normal-weight subjects. Studies in our laboratory also permitted the separation of sensory and nonsensory factors in body image perception. In all but one instance, no differences were found overall between the ability of obese and normal-weight subjects to detect overall changes in body size. Importantly, however, obese subjects are better at detecting changes in their body size when the image is distorted to be too thin as compared to too wide. Both obese and normal-weight men require about a 3%–7% change in the width of their body size in order to detect the change reliably. Correlations between a range of body mass index values and body size estimation accuracy indicated no relationship between these variables. Numerous studies in other laboratories asked men to place their body size into discrete categorizes, ranging from thin to obese. Researchers found that overweight and obese men underestimate their weight status, and that men are less accurate in their categorizations than are women. Cultural influences have been found to be important, with body size underestimations occurring in cultures

Only Behavioral But Not Self-Report Measures of Speech Perception Correlate with Cognitive Abilities.

2016-01-01

Good speech perception and communication skills in everyday life are crucial for participation and well-being, and are therefore an overarching aim of auditory rehabilitation. Both behavioral and self-report measures can be used to assess these skills. However, correlations between behavioral and self-report speech perception measures are often low. One possible explanation is that there is a mismatch between the specific situations used in the assessment of these skills in each method, and a more careful matching across situations might improve consistency of results. The role that cognition plays in specific speech situations may also be important for understanding communication, as speech perception tests vary in their cognitive demands. In this study, the role of executive function, working memory (WM) and attention in behavioral and self-report measures of speech perception was investigated. Thirty existing hearing aid users with mild-to-moderate hearing loss aged between 50 and 74 years completed a behavioral test battery with speech perception tests ranging from phoneme discrimination in modulated noise (easy) to words in multi-talker babble (medium) and keyword perception in a carrier sentence against a distractor voice (difficult). In addition, a self-report measure of aided communication, residual disability from the Glasgow Hearing Aid Benefit Profile, was obtained. Correlations between speech perception tests and self-report measures were higher when specific speech situations across both were matched. Cognition correlated with behavioral speech perception test results but not with self-report. Only the most difficult speech perception test, keyword perception in a carrier sentence with a competing distractor voice, engaged executive functions in addition to WM. In conclusion, any relationship between behavioral and self-report speech perception is not mediated by a shared correlation with cognition.

It is obvious that self-perception can play an important role in the development of self-management behaviours among adolescents with diabetes to promote their health and quality of life. This study seeks to explain self-perception in adolescents with diabetes. This qualitative study, which is of "grounded theory" type, was performed in 2013 in Ahvaz, Iran, through semi-structured interviews with ten adolescents with type 1 diabetes, two parents and a nurse, who were chosen objectively. Data analysis was performed using Strauss and Corbin 1998 method. Four main theme was obtained from the analysis of data, and the consequence theme was inferred as follows: getting insight (knowledge acquisition and belief management), perceiving similarities with others (not hiding the disease, showing the illness is normal, and accepting an active role in the family), and self-care management (independent control of food and treatment regimen and understanding of capabilities to manage the future of life and manage the daily activities of life), and life satisfaction (perception of being healthy and having a normal life). Getting insight into the disease is the most important part of perceiving similarities with others and offering self-care, which can provide a person's positive perception of himself/herself and the illness, as well as life satisfaction for their adolescent over time. These results are an operational guide for personnel providing health care services, especially diabetes specialist nurses.

In bistable vision, subjective perception wavers between two interpretations of a constant ambiguous stimulus. This dissociation between conscious perception and sensory stimulation has motivated various empirical studies on the neural correlates of bistable perception, but the neurocomputational mechanism behind endogenous perceptual transitions has remained elusive. Here, we recurred to a generic Bayesian framework of predictive coding and devised a model that casts endogenous perceptual transitions as a consequence of prediction errors emerging from residual evidence for the suppressed percept. Data simulations revealed close similarities between the model's predictions and key temporal characteristics of perceptual bistability, indicating that the model was able to reproduce bistable perception. Fitting the predictive coding model to behavioural data from an fMRI-experiment on bistable perception, we found a correlation across participants between the model parameter encoding perceptual stabilization and the behaviourally measured frequency of perceptual transitions, corroborating that the model successfully accounted for participants' perception. Formal model comparison with established models of bistable perception based on mutual inhibition and adaptation, noise or a combination of adaptation and noise was used for the validation of the predictive coding model against the established models. Most importantly, model-based analyses of the fMRI data revealed that prediction error time-courses derived from the predictive coding model correlated with neural signal time-courses in bilateral inferior frontal gyri and anterior insulae. Voxel-wise model selection indicated a superiority of the predictive coding model over conventional analysis approaches in explaining neural activity in these frontal areas, suggesting that frontal cortex encodes prediction errors that mediate endogenous perceptual transitions in bistable perception. Taken together, our current work

Understanding physical (in-) activity, overweight, and obesity in childhood: Effects of congruence between physical self-concept and motor competence.

Both the physical self-concept and actual motor competence are important for healthy future physical activity levels and consequently decrease overweight and obesity in childhood. However, children scoring high on motor competence do not necessarily report high levels of physical self-concept and vice versa, resulting in respective (in-) accuracy also referred to as (non-) veridicality. This study examines whether children's accuracy of physical self-concept is a meaningful predictive factor for their future physical activity. Motor competence, physical self-concept and physical activity were assessed in 3 rd grade and one year later in 4 th grade. Children's weight status was categorized based on WHO recommendations. Polynomial regression with Response surface analyses were conducted with a quasi-DIF approach examining moderating weight status effects. Analyses revealed that children with higher motor competence levels and higher self-perceptions show greater physical activity. Importantly, children who perceive their motor competence more accurately (compared to less) show more future physical activity. This effect is strong for underweight and overweight/obese children, but weak for normal weight children. This study indicates that an accurate self-perception of motor competence fosters future physical activity beyond single main effects, respectively. Hence, the promotion of actual motor competence should be linked with the respective development of accurate self-knowledge.

General practitioners (GPs) play an important role in the management of patients who are overweight or obese. Previous research suggests that GPs' physical characteristics may influence patients' perceptions of health care received during consultations, mediating the likelihood of patients following health advice provided by GPs. This study aimed to explore patients' perceptions of their GP's health status and its influence on patients' perceptions of healthy eating and exercise advice. An interpretive approach to phenomenology underpinned the qualitative inquiry and study design. Twenty-one participants (aged 55.9 ± 6.5 years; 14 females, 7 males) who had previously received healthy eating and/or exercise advice from a GP participated in an individual semi-structured interview. A constant comparison approach to thematic analysis was conducted. Participants identified three key indicators of perceived health of their GP. These included the GP's physical appearance, particularly weight status; perceived absence of ill health; and disclosure of a GP's health behaviours. Participants expressed favourable perceptions of the weight status of their GP. Participants expected their GP to be a healthy role model and often, but not always, felt more confident receiving advice from a GP that they perceived as healthy. The findings highlight that a GP's perceived health status influences patients' perceptions of the health advice received during consultations. These findings provide a foundation for future research that may allow GPs to modify patients' perceptions of their health status in order to facilitate behaviour change in overweight or obese patients.

Full Text Available Introduction & Objective: The survey of smoking as the most toxic, common and cheapest ad-diction, and its psychological and demographic variables especially among the youth who are efficient and constructive individuals of the society is of great importance. This study was performed to compare efficacy and threat perception in predicting cigarette smoking among university students based on Expended Parallel Process Model (EPPM. Material & Methods: This cross sectional descriptive study was carried out on 700 college stu-dents of Hamadan recruited with a stratified sampling method. The participants completed a self-administered questionnaire including demographic characteristics, smoking status and EPPM Data analysis was done with the SPSS software (version 16, using t-test, one way ANOVA, Pierson correlation and logistic regression methods. Results: The average scores of threat and efficacy perception were 39.7 and 38.6, respectively. The prevalence of cigarette smoking among participants was 27.1 percent. Also, there were significant differences between the average score of efficacy perception and age, gender, his-tory of drug abuse and dwelling of students (P<0.05. Efficacy and threat perception both predicted student cigarette smoking. Conclusions: Cognitive mediating process of threat perception was a more powerful predictor of cigarette smoking as an unsafe behavior. Therefore, increasing self efficacy and response efficacy of university students aimed at facilitating the acceptance of safe behavior could be note-worthy as a principle in education.

The aim of the current research was to explore the relationship between motor competence, physical fitness and self-perception, and to study to which extent this relationship may vary by gender. A sample of 67 children (mean age 11.46 years, SD 0.27) completed Harter's Self-Perception Profile for Children (SPPC), the Movement Assessment Battery for Children (MABC) and the Test of Physical Fitness (TPF) to assess self-perception, motor competence and physical fitness. The SPPC was stronger related to total score on TPF than to total score on MABC. However, when looking at boys and girls separately, this result was found for the boys only. In the group in general, total scores on both TPF and MABC correlated significantly with three of the domains of SPPC (social acceptance, athletic competence and physical appearance) and general self-worth. This relationship varied by gender. Interestingly, TPF was highest correlated with perception of athletic competence in boys but with perception of social acceptance in girls. A high and significant correlation was found between physical fitness and motor competence for both genders. The results indicated a strong relationship between physical fitness, motor competence and self-perception in children that varied by gender. This implies that all these factors are essential contributions in order to facilitate participation in physical activity in children. © 2011 Blackwell Publishing Ltd.

Wasylkiw, Louise; Butler, Nicole A

2014-08-01

Undergraduate women (N = 143) completed self-reports on exercise behavior, body orientation, body appreciation, and body-related talk. Results showed that conversations about weight loss/dieting and conversations about exercise differentially predicted body appreciation. Importantly, multiple regression analyses showed that the relationship between talk type and body appreciation was explained by the object-process dichotomy: Conversations about exercise oriented women to consider what their bodies can do which, in turn, predicted appreciation of one's body. In contrast, the relationship between conversations about weight loss/dieting and body appreciation was mediated by negative attitudes about one's body but not by an object orientation. © The Author(s) 2013.

While mother's perception of child's weight is important for the success of early childhood obesity prevention programs, few studies have examined that of Asian Americans. Our study examined their perception and compared it to that of mothers of other racial/ethnic groups. Cross-sectional study of 2,051 randomly selected mothers of children aged 2-5 years living in Los Angeles County who were enrolled in the Special Supplemental Nutrition Program for Women Infants and Children (WIC). The primary outcome was mother's perception of child's weight. We found that Asian American mothers were 2.12 (95% CI: 1.27-3.54) times as likely as Hispanic mothers to accurately perceive their children's weight, adjusting for child's age, sex and birthweight, and mother's age and education. However, this relationship disappeared after adjusting for mother's BMI. We did not find differences in perception of child's weight among non-Hispanic White, non-Hispanic Black and Hispanic mothers. It appears that Asian American mothers' increased accurate perception of child's weight status can be partially explained by their lower prevalence of obesity. Our findings suggest that early childhood obesity prevention programs should consider the weight status of mothers.

Drawing from self-determination theory (Ryan & Deci, 2002, Overview of self-determination theory: An organismic-dialectical perspective. In E. L. Deci & R. M. Ryan (Eds.), Handbook of self-determination research (pp. 3-33). Rochester, NY: The University of Rochester Press.), we examined how individuals' psychological needs, motivation, and behaviours (i.e., physical activity and eating) associated with weight management could be predicted by perceptions of their important others' supportive and controlling behaviours. Using a cross-sectional survey design, 235 participants (mean age = 27.39 years, SD = 8.96 years) completed an online questionnaire. Statistical analyses showed that when important others were perceived to be more supportive, participants reported higher levels of more optimal forms of motivation for weight management, which in turn predicted more physical activity and healthy eating behaviours. In contrast, when important others were perceived to be controlling, participants reported higher levels of less optimal forms of motivation, which in turn predicted less physical activity and healthy eating behaviours, as well as more unhealthy eating behaviours. Significant indirect effects were also found from perceived support and control from important others to physical activity and eating behaviours, all in the expected directions. The findings support the importance of important others providing support and refraining from controlling behaviours in order to facilitate motivation and behaviours conducive to successful weight management. What is already known on this subject? Autonomy support is related to basic need satisfaction and autonomous motivation in the context of weight management. In turn, these variables are related to adaptive outcomes for weight management. What does this study add? Measurement of perceived controlling behaviours by important others. Measurement of perceived need thwarting. Structural model on how important others affect

In this study, we aimed to assess the relationship between normative and perceived orthodontic treatment need associated with quality of life, self-esteem, and self-perception. The sample included 248 schoolchildren aged 12 years. The normative aspect of orthodontic treatment was assessed by the Dental Health Component and the Aesthetic Component of the Index of Orthodontic Treatment Need. The subjects were further evaluated for their oral health-related quality of life, self-esteem, and self-perception of oral esthetics. The Aesthetic Component of the Index of Orthodontic Treatment Need was considered as the response variable, and generalized linear models estimated by the GENMOD procedure (release 9.3, 2010; SAS Institute, Cary, NC). Model 1 was estimated with only the intercept, providing the basis for evaluating the reduction in variance in the other models studied; then the variables were tested sequentially, considering P ≤0.05 as the criterion for remaining in the model. In the model, self-perception and self-esteem were statistically significant in relation to the perceived need for treatment. The normative need was significantly associated with the outcome variable and was not influenced by independent variables. The normative need for orthodontics treatment was not overestimated by the perceived need, and the perceived need was not influenced by sex and the impact on quality of life.

Objective To examine, in adolescents with mild to moderate malocclusion, the relationship between self-concept and demographic characteristics, a clinical assessment of malocclusion, self-perception of malocclusion, and self-perception of facial attractiveness. Methods and Materials Fifty-nine consecutive patients ages 9 to 15 years scheduled for initial records in a graduate orthodontic clinic consented to participate. Each subject independently completed the Multidimensional Self-Concept Scale (MSCS), the Facial Image Scale, and the Index of Treatment Need–Aesthetic Component (IOTN-AC). Peer Assessment Rating (PAR) scores were obtained from the patients’ diagnostic dental casts. Forward multiple-regression analysis with a backward overlook was used to analyze the effect of the demographic, clinical, and self-perception measures on each of the six self-concept (MSCS) domains. Results Self-perception of the dentofacial region was the only statistically significant predictor (P < .05) for the Global, Competence, Affect, Academic, and Physical domains of self-concept, while age, parental marital status, and the adolescent's self-perception of the dentofacial region were statistically significant predictors (P < .05) of Social Self-Concept. Conclusion The self-perceived level of the attractiveness or “positive” feelings toward the dentofacial region is more strongly related to self-concept than the severity of the malocclusion as indicated by the PAR score or by the adolescent's perception of their malocclusion.

Self-esteem is implied as a factor in the development of eating disorders. In adolescence peers have an increasing influence. Support for the role of self-esteem in eating disorders is ambiguous and little is known about the influence of social status as judged by others. The present study investigates whether self-esteem and peer status in early adolescence are associated with eating pathology in young adulthood. This study is part of TRAILS, a longitudinal cohort study on mental health and social development from preadolescence into adulthood. At age 11, participants completed the Self-Perception Profile for Children, assessing global self-esteem and self-perceptions regarding social acceptance, physical appearance, and academic competence. At age 13, peer status among classmates was assessed regarding likeability, physical attractiveness, academic performance, and popularity in a subsample of 1,007 participants. The Eating Disorder Diagnostic Scale was administered at age 22. The present study included peer-nominated participants with completed measures of self-perception at age 11 and eating pathology at age 22 (N = 732; 57.8% female). In a combined model, self-perceived physical attractiveness at age 11 and peer popularity at age 13 were inversely correlated with eating pathology at 22 years, while likeability by peers at age 13 was positively related to eating pathology. Both self-perceptions and peer status in early adolescence are significant predictors of eating pathology in young adults. Specific measures of self-esteem and peer-perceived status may be more relevant to the prediction of eating pathology than a global measure of self-esteem. © 2018 The Authors International Journal of Eating Disorders Published by Wiley Periodicals, Inc.

This research examines the association between measured body mass index (BMI) and the perception of BMI by young students. Moreover, this research tests the importance of BMI and self-concept, in order to predict body dissatisfaction in high school students. The sample consisted of 2087 individuals from different high schools in Extremadura, Spain, both males (n = 1046) and females (n = 1041), ranging in age from 15 to 17 years old (M = 15.42; SD = 0.86). Initially, participants' BMIs were assessed through anthropometry. Later, all individuals were asked about their weight and height, and their self-reported BMI was calculated. Participants also answered a questionnaire about their perception of self-concept, as well as completed a test about body image perception using Stunkard images. Outcomes revealed that factors concerning self-concept and perceived BMI explained body dissatisfaction. Finally, results are discussed with the aim of improving knowledge in body dissatisfaction context. © 2018 International Union of Psychological Science.

To evaluate if self-efficacy (SE) and financial incentives (FI) mediate the effect of health behavior on weight loss in a group of overweight and obese nursing-home employees participating in a 16-week weight-loss intervention with 12-week follow-up. Ninety nine overweight/obese (body mass index [BMI] > 25) employees from four nursing-homes participated, with a mean age of 46.98 years and BMI of 35.33. Nursing-homes were randomized to receiving an incentive-based intervention (n = 51) and no incentive (n = 48). Participants' health behaviors and eating and exercise self-efficacy (Ex-SE) were assessed at week 1, 16, and 28 using a self-reported questionnaire. Mediation and moderated mediation analysis assessed relationships among these variables. Eating self-efficacy (Eat-SE) and Ex-SE were significant mediators between health behaviors and weight loss (P self-efficacy (P = 0.00) on weight loss. Self-efficacy and FI may affect weight loss and play a role in weight-loss interventions.

Few researchers have examined multi-dimensional physical self-concept among athletes with disabilities despite extensive evidence indicating the value of such an approach. To describe multidimensional self-concept and to predict both physical activity (PA) and self-esteem using various dimensions of physical self-concept (e.g., endurance, strength). The study was a one-time cross-sectional design involving self-report questionnaires. Participants (n = 50) were adolescents and adult athletes with physical disabilities (M age = 26.5, SD = 10.1) who completed the short version of the Physical Self-Description Questionnaire (PSDQ-S). Athletes reported neutral to positive perceptions of multidimensional physical self-concept (M's ranging from 3.3 to 5.9 of 6). Using multiple regression analyses, we were able account for 29 and 47 percent of the variance in global self-concept and PA, respectively. Global physical self-concept and strength self-concept were important in predicting global self-concept and PA, respectively. These findings support the promotion of weight training programs specifically and PA programs more generally for people with disabilities. Copyright © 2012 Elsevier Inc. All rights reserved.

2011-12-01

The relative contributions of self-efficacy, self-regulation, and self-handicapping student procrastination were explored. College undergraduate participants (N = 138; 40 men, 97 women, one not reporting sex) filled out the Procrastination Scale, the Self-Handicapping Scale-Short Form, and the Self-regulation and Self-handicapping scales of the Motivated Strategies for Learning Questionnaire. A hierarchical regression of the above measures indicated that self-efficacy, self-regulation, and self-handicapping all predicted scores on the Procrastination Scale, but self-regulation fully accounted for the predictive power of self-efficacy. The results suggested self-regulation and self-handicapping predict procrastination independently. These findings are discussed in relation to the literature on the concept of "self-efficacy for self-regulation" and its use in the field of procrastination research.

Objective To investigate whether anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other specified feeding and eating disorders (OSFED), including purging disorder (PD), subthreshold BN, and BED at ages 14 and 16, are prospectively associated with later depression, anxiety disorders, alcohol and substance use, and self-harm. Method Eating disorders were ascertained at 14 and 16 years of age in 6,140 youth at age 14 (58% of those eligible) and 5,069 at age 16 (52% of those eligible) as part of the prospective Avon Longitudinal Study of Parents and Children (ALSPAC). Outcomes (depression, anxiety disorders, binge drinking, drug use, deliberate self-harm, weight status) were measured using interviews and questionnaires about 2 years following predictors. Generalized estimating equation models adjusting for gender, socio-demographic variables, and prior outcome were used to examine prospective associations between eating disorders and each outcome. Results All eating disorders were predictive of later anxiety disorders. AN, BN, BED, PD, and OSFED were prospectively associated with depression (respectively AN: odds ratio [OR]=1.39 [95% CIs: 1.00-1.94]; BN: OR=3.39[1.25-9.20]; BED: OR=2.00 [1.06-3.75]; PD: OR=2.56 [1.38-4.74]). All eating disorders but AN predicted drug use and deliberate self-harm (BN: OR=5.72[2.22-14.72], PD: OR=4.88[2.78-8.57], subthreshold BN: OR=3.97[1.44-10.98], subthreshold BED: OR=2.32[1.43-3.75]). Whilst BED and BN predicted obesity (respectively OR=3.58 [1.06-12.14] and OR=6.42 [1.69-24.30]), AN was prospectively associated with underweight. Conclusions Adolescent eating disorders, including subthreshold presentations, predict negative outcomes, including mental health disorders, substance use, deliberate self-harm, and weight outcomes. This study highlights the high public health and clinical burden of eating disorders among adolescents. PMID:26210334

Previous research has indicated that both boys and girls strive for a slim body, with boys having an additional focus on a muscular body build. The current study was designed to evaluate the utility of a biopsychosocial model to explain body image and body change strategies among children. The study evaluated changes over time in body image and strategies to lose weight and increase muscles among 132 normal weight and 67 overweight boys (mean age = 9.23 years) and 158 normal weight and 55 overweight girls (mean age = 9.33 years). The predictive role of BMI, positive and negative affect, self-esteem and perceived sociocultural pressures to lose weight or increase muscle on body image and body change strategies over a 16 month period was evaluated. All participants completed the questionnaire on both occasions. The results demonstrated that both overweight boys and girls were more likely to be dissatisfied with their weight, place more importance on their weight, engage in more strategies to lose weight as well as perceive more pressure to lose weight. Overweight boys and girls were also more likely to report lower levels of self-esteem and positive affect, and higher levels of negative affect, and reported a reduction in their self-esteem over time. Regression analyses demonstrated that among overweight boys, low self-esteem and high levels of perceived pressure to lose weight predicted weight dissatisfaction; for overweight girls, weight dissatisfaction was also predicted by low levels of self-esteem. The implication of these findings in terms of factors contributing to the adoption of health risk behaviors among children is discussed.

To describe African American and White women's perceptions of weight gain, physical activity, and nutrition during pregnancy and to explore differences in perceptions by race. Qualitative interview study. Two Ob/Gyn clinics in South Carolina, USA. Thirty pregnant women (15 African American, 15 White) between 20 and 30 weeks gestation, equally represented across pre-pregnancy BMI categories (10 normal weight, 10 overweight, and 10 obese). White women more frequently described intentions to meet weight gain, physical activity, and dietary guidelines in pregnancy than African American women. African American women were more concerned with inadequate weight gain while White women more commonly expressed concerns about excessive weight gain. More White women discussed the importance of physical activity for weight management. Regardless of race, few women described risks of excessive weight gain or benefits of physical activity as it relates to the baby's health. The primary cited barrier of healthy eating was the high cost of fresh produce. Several knowledge gaps as well as race differences were identified in women's perceptions and intentions toward weight gain, physical activity, and nutrition during pregnancy. Future interventions should seek to educate women about common misperceptions. It may be necessary to culturally tailor gestational weight gain interventions to optimise health outcomes.

Patients' perceptions of their general practitioner's health and weight influences their perceptions of nutrition and exercise advice received

Directory of Open Access Journals (Sweden)

Fraser SE

2013-12-01

Full Text Available INTRODUCTION: General practitioners (GPs play an important role in the management of patients who are overweight or obese. Previous research suggests that GPs' physical characteristics may influence patients' perceptions of health care received during consultations, mediating the likelihood of patients following health advice provided by GPs. This study aimed to explore patients' perceptions of their GP's health status and its influence on patients' perceptions of healthy eating and exercise advice. METHODS: An interpretive approach to phenomenology underpinned the qualitative inquiry and study design. Twenty-one participants (aged 55.9 ± 6.5 years; 14 females, 7 males who had previously received healthy eating and/or exercise advice from a GP participated in an individual semi-structured interview. A constant comparison approach to thematic analysis was conducted. FINDINGS: Participants identified three key indicators of perceived health of their GP. These included the GP's physical appearance, particularly weight status; perceived absence of ill health; and disclosure of a GP's health behaviours. Participants expressed favourable perceptions of the weight status of their GP. Participants expected their GP to be a healthy role model and often, but not always, felt more confident receiving advice from a GP that they perceived as healthy. CONCLUSION: The findings highlight that a GP's perceived health status influences patients' perceptions of the health advice received during consultations. These findings provide a foundation for future research that may allow GPs to modify patients' perceptions of their health status in order to facilitate behaviour change in overweight or obese patients.

Simultaneous contributions of self-esteem, depression, and anxiety to weight and perceived physical health in young adults is understudied. A diverse sample of 424 young adults completed measures of shape/weight based self-esteem, depression, anxiety, and perceived physical health. Height and weight were measured to calculate body mass index (BMI). Latent profile analysis was conducted to derive patterns of depression, anxiety, and shape/weight based self-esteem. Then, we examined the association of the profiles with weight status and perceived physical health. Three profiles emerged: (1) High Shape/Weight Influence (HSWI); (2) Low Shape/Weight, Depression, & Anxiety Influence (LSWDAI); and (3) High Depression & Anxiety Influence (HDAI). The HSWI profile had significantly higher BMI than the LSWDAI and HDAI profiles, and significantly lower perceived physical health than the LSWDAI profile. Over emphasis on shape/weight, regardless of depression and anxiety, is associated with elevated weight and negative internalized health views. Copyright © 2018 Elsevier Ltd. All rights reserved.

Alteration in self-perception is a salient feature in major depression. Hyperactivity of anterior cortical midline regions has been implicated in this phenomenon in depressed adults. Here, we extend this work to depressed adolescents during a developmental time when neuronal circuitry underlying the sense of self matures by using task-based functional magnetic resonance imaging (fMRI) and connectivity analyses. Twenty-three depressed adolescents and 18 healthy controls (HC) viewed positive and negative trait words in a scanner and judged whether each word described them ('self' condition) or was a good trait to have ('general' condition). Self-perception scores were based on participants' endorsements of positive and negative traits during the fMRI task. Depressed adolescents exhibited more negative self-perceptions than HC. Both groups activated cortical midline regions in response to self-judgments compared to general-judgments. However, depressed adolescents recruited the posterior cingulate cortex/precuneus more for positive self-judgments. Additionally, local connectivity of the dorsal medial prefrontal cortex was reduced during self-reflection in depressed adolescents. Our findings highlight differences in self-referential processing network function between depressed and healthy adolescents and support the need for further investigation of brain mechanisms associated with the self, as they may be paramount to understanding the etiology and development of major depressive disorder.

The influence, legitimacy and application of Evidence Based Medicine (EBM) in the world is growing as a tool that integrates, the best available evidence to decision making in patient care. Our goal was to identify the relationship between self-perception about the relevance of Evidence Based Medicine (EBM) and the degree of basic knowledge of this discipline in a group of physicians. A survey was carried out in a third level public hospital in Mexico City. Self-perception was measured by means of a structured scale, and the degree of knowledge through parameter or "rubrics" methodology. A total of 320 questionnaires were given to 55 medical students (17 %); 45 pre-graduate medical interns (14 %); 118 medical residents (37 %) and 102 appointed physicians of different specialties (32 %). Self-perception of EBM: The majority of those surveyed (n = 274, 86 %) declared that they were very or moderately familiar with EBM. The great majority (n = 270, 84 %) believe that EBM is very important in clinical practice and 197 physicians (61 %) said that they implement it always or usually. The global index of self-perception was 75 %. Knowledge of EBM: Definition of EBM; Seven of those surveyed (2 %) included 3 of the 4 characteristics of the definition, 82 (26 %) mentioned only two characteristics of the definition, 152 (48 %) mentioned only one characteristic and 79 (25 %) did not include any characteristic of EBM. Phases of the EBM process: The majority of those surveyed (n = 218, 68 %) did not include the steps that characterize the practice of EBM, of which 79 participants (25 %) mentioned elements not related to it. The global index of knowledge was 19 %. The majority of the surveyed physicians have a high self-perception of the relevance of EBM. In spite of this, the majority of them did not know the characteristics that define the EBM and phases of the process for its practice. A major discrepancy was found between self-perception and the

To improve understanding of directionality in the dynamic relationships among psychosocial predictors of behavioral changes associated with weight loss. In women with obesity participating in a new behavioral weight-loss treatment that emphasizes physical activity (n = 53; body mass index = 34.7 ± 3.3 kg/m 2 ), mediation and moderated-mediation models were fit to assess directionality in the self-efficacy-self-regulation change relationship and additional effects of mood change and its basis on fruit/vegetable intake and physical activity behaviors through month 6 and from months 6 to 24. Self-regulation was a stronger predictor of change in self-efficacy than vice versa. Mood change did not moderate the relationships significantly between changes in self-efficacy and/or self-regulation, and weight loss behavior. Emotional eating significantly changed mediated relationships between changes in mood and fruit/vegetable intake through month 6 (95% confidence interval, -0.05 to 0.00). Findings clarified relationships of self-efficacy, self-regulation, and mood in the prediction of weight loss behaviors, and informed behavioral treatments for improved outcomes.

The aim of the present study was to investigate the neural bases of cooperative behaviors and social self-perception underlying the execution of joint actions by using a hyperscanning brain paradigm with functional near-infrared spectroscopy (fNIRS). We firstly found that an artificial positive feedback on the cognitive performance was able to affect the self-perception of social position and hierarchy (higher social ranking) for the dyad, as well as the cognitive performance (decreased error rate, ER, and response times, RTs). In addition, the shared cognitive strategy was concurrently improved within the dyad after this social reinforcing. Secondly, fNIRS measures revealed an increased brain activity in the postfeedback condition for the dyad. Moreover, an interbrain similarity was found for the dyads during the task, with higher coherent prefrontal cortex (PFC) activity for the interagents in the postfeedback condition. Finally, a significant prefrontal brain lateralization effect was revealed, with the left hemisphere being more engaged during the postfeedback condition. To summarize, the self-perception, the cognitive performance, and the shared brain activity were all reinforced by the social feedback within the dyad.

Full Text Available Previous researchers have described the relation between physical self-concept and body mass in adolescents, but those relationships have not been clearly specified by gender. The purpose of this study is to explore physical self-concepts of normal-weight and over-weight Serbian adolescents with respect to gender. The sample consisted of 417 primary school students (229 boys and 188 girls with the average age 13.6 (SD=0.73 years who were divided into normal-weight and overweight groups according to body mass index. To assess the multidimensional physical self-concept, Physical Self-Description Questionnaire (PSDQ was administered. Results showed that overweight adolescents had significantly lower scores than normal-weight on all PSDQ scales except Health and Strength. Differences were greater among girls than boys. Discriminant analysis showed that the scales Body Fat, Endurance and Sports Competence best differentiated normal-weight boys from other students. Also, discriminant analysis showed that, besides the scale Body Fat, scales Flexibility, Self-Esteem, and Coordination best differentiated normal-weight girls from other students. Results indicate that for better understanding of the relationship between adolescent’s physical self-concept and body mass one must take gender into account. Results are potentially valuable for preventing overweight through physical education.

The Impact of Regular Self-weighing on Weight Management: A Systematic Literature Review

Directory of Open Access Journals (Sweden)

Welsh Ericka M

2008-11-01

Full Text Available Abstract Background Regular self-weighing has been a focus of attention recently in the obesity literature. It has received conflicting endorsement in that some researchers and practitioners recommend it as a key behavioral strategy for weight management, while others caution against its use due to its potential to cause negative psychological consequences associated with weight management failure. The evidence on frequent self-weighing, however, has not yet been synthesized. The purpose of this paper is to evaluate the evidence regarding the use of regular self-weighing for both weight loss and weight maintenance. Methods A systematic literature review was conducted using the MEDLINE, CINAHL, and PsycINFO online databases. Reviewed studies were broken down by sample characteristics, predictors/conditions, dependent measures, findings, and evidence grade. Results Twelve studies met the inclusion/exclusion criteria, but nearly half received low evidence grades in terms of methodological quality. Findings from 11 of the 12 reviewed studies indicated that more frequent self-weighing was associated with greater weight loss or weight gain prevention. Specifically, individuals who reported self-weighing weekly or daily, typically over a period of several months, held a 1 to 3 kg/m2 (current advantage over individuals who did not self-weigh frequently. The effects of self-weighing in experimental studies, especially those where self-weighing behaviors could be isolated, were less clear. Conclusion Based on the consistency of the evidence reviewed, frequent self-weighing, at the very least, seems to be a good predictor of moderate weight loss, less weight regain, or the avoidance of initial weight gain in adults. More targeted research is needed in this area to determine the causal role of frequent self-weighing in weight loss/weight gain prevention programs. Other open questions to be pursued include the optimal dose of self-weighing, as well as the

Stigmatization and self-perception in children with atopic dermatitis

Full Text Available Pavel V Chernyshov Department of Dermatology and Venereology, National Medical University, Kiev, Ukraine Abstract: Atopic dermatitis (AD is one of the most common skin diseases. Prevalence of AD is highest in childhood. Because of chronicity and often visible lesions, AD may lead to stigmatization and problems with self-perception. However, problems of self-perception and stigmatization in AD children are poorly studied. Literature data on general tendencies of children’s development, clinical course, and epidemiologic tendencies of AD in different age groups make it possible to highlight three main periods in the formation of self-perception and stigmatization. The first period is from early infancy till 3 years of age. The child’s problems in this period depend on parental exhaustion, emotional distress, and security of the mother–child attachment. The child’s AD may form a kind of vicious circle in which severe AD causes parental distress and exhaustion that in turn lead to exacerbation of AD and psychological problems in children. The second period is from 3 till 10 years of age. During this period, development of AD children may be influenced by teasing, bullying, and avoiding by their peers. However, the majority of children in this age group are very optimistic. The third period is from 10 years till adulthood. Problems related to low self-esteem are characteristic during this period. It is important to identify children with AD and their parents who need psychological help and provide them with needs-based consultation and care. Appropriate treatment, medical consultations, and educational programs may help to reduce emotional problems in AD children and their parents.

More than one-third of adults in the United States are obese, with a higher prevalence among older adults. Obesity among older adults is a major cause of physical dysfunction, hypertension, diabetes, and coronary heart diseases. Many people who engage in lifestyle weight loss interventions fail to reach targeted goals for weight loss, and most will regain what was lost within 1-2 years following cessation of treatment. This variability in treatment efficacy suggests that there are important phenotypes predictive of success with intentional weight loss that could lead to tailored treatment regimen, an idea that is consistent with the concept of precision-based medicine. Although the identification of biochemical and metabolic phenotypes are one potential direction of research, neurobiological measures may prove useful as substantial behavioral change is necessary to achieve success in a lifestyle intervention. In the present study, we use dynamic brain networks from functional magnetic resonance imaging (fMRI) data to prospectively identify individuals most likely to succeed in a behavioral weight loss intervention. Brain imaging was performed in overweight or obese older adults (age: 65-79 years) who participated in an 18-month lifestyle weight loss intervention. Machine learning and functional brain networks were combined to produce multivariate prediction models. The prediction accuracy exceeded 95%, suggesting that there exists a consistent pattern of connectivity which correctly predicts success with weight loss at the individual level. Connectivity patterns that contributed to the prediction consisted of complex multivariate network components that substantially overlapped with known brain networks that are associated with behavior emergence, self-regulation, body awareness, and the sensory features of food. Future work on independent datasets and diverse populations is needed to corroborate our findings. Additionally, we believe that efforts can begin to

Research purpose: The purpose of this study was to investigate the prevalence of selfperception accuracy amongst the managers and to explore the patterns of interaction between self-perception accuracy (regarding their leadership behaviour and perceived transformational leadership behaviour (as measured by composite ‘other’-ratings. Motivation of the study: Research has shown that managers in various work environments typically overestimate their own level of competence and that this could impact on the effectiveness of their leadership behaviour. This phenomenon has however not yet been researched in the context of South African higher education institutions. Research design, approach and method: A quantitative cross-sectional study of the relationship between self-perception accuracy and leadership effectiveness was conducted amongst the total population (N = 204 of staff members in management positions. The response rate was 67% and the realised sample consisted of 137 managers. Leadership behaviour was measured by means of behavioural ratings on the following five dimensions of the Leadership Practices Inventory (LPI: ‘Challenging the process’, ‘Inspiring a shared vision’, ‘Enabling others to act’, ‘Modelling the way’ and ‘Encouraging the heart’. Main findings: Statistically significant discrepancies were found between self- and observer ratings on all five leadership dimensions, indicating a probable overestimation of their own capabilities. Results further provide evidence that perceived leadership effectiveness on three of the five transformational leadership practices varied as a function of the self-perceptions of managers. Practical/managerial implications: Managerial development practices should sensitise managers to what is essentially introspective and provide opportunities for them to reflect upon and question their leadership practices. Contribution/value-add: A challenge for higher education is to embark on feedback intensive

The Worth Index was administered to 176 Division I athletes who were competing in team and individual sports at Brigham Young University. The purpose of the study was to measure and compare their perceptions of worth and self-esteem. The Worth Index is a valid tool measuring whether an individual believes worth and self-esteem are earned by way of performance (conditional) or are inherent (unconditional). The Worth Index measures perceptions of basic human worth and worth as related to personal security, performance, and the physical self. The four subscales represent these four categories. There were no significant differences between the perceptions of athletes in team and individual sports on any of the subscales of the Worth Index. However, on each subscale, all participants combined rated themselves significantly higher on unconditional worth than conditional worth.

Full Text Available Caring for a demented family member has been associated with burden. Studies concerning health self-perception of family caregivers are still scarce. OBJECTIVE: To investigate caregivers perceived health and to look into relationships with patients and caregivers' sociodemographic and clinical data. METHOD: Dyads of dementia outpatients and family caregivers (n=137 were assessed with Mini Mental State Examination, Functional Activities Questionnaire, Neuropsychiatric Inventory and Clinical Dementia Rating. Caregivers answered Sociodemographic Questionnaire, Beck Depression and Anxiety Inventories, Zarit Burden Interview and Maslach Burnout Inventory. RESULTS: Caregivers poor perceived health was associated with emotional exhaustion, burden, depression and anxiety. Logistic regression analyses revealed caregivers' age, anxiety and physical problem as the main predictors of health self-perception. CONCLUSION: Aged family caregivers with anxiety who also report physical problem characterize a group at risk for poor self-perceived health. Evaluation of health self-perception may be useful for designing interventions to improve anxiety and physical health.

The purpose of this study was to examine adolescents' physical self-perceptions and their associations with physical activity using a longitudinal perspective. Utilizing data from the Physical Activity in Scottish Schoolchildren (PASS) study, changes in exercise self-efficacy, perceived competence, global self-esteem and physical self-worth were assessed among a sample of 641 Scottish adolescents from age 11-15 years. Girls reported lower levels of perceived competence, self-esteem and physical self-worth than boys at each age. Furthermore, girls' physical self-perceptions decreased markedly over time. Among boys, only perceived competence decreased, while global self-esteem increased. Baseline physical activity was a significant predictor of later activity levels for both genders. Findings demonstrate the importance of physical self-perceptions in relation to physical activity behavior among adolescents. Among older boys, high perceived competence increased the odds of being active by 3.8 times. Among older girls, high exercise self-efficacy increased the odds of being active by 5.2 times. There is a need for early interventions which promote increased physical literacy and confidence, particularly among girls.

Background Halitosis or oral malodor is defined as an unpleasant breath odor. It can become a serious problem affecting individuals’ social communication and self-confidence. Furthermore, it is a discomforting issue for the people around the person affected, because they consider it embarrassing to inform the person of the problem. Aim This study was designed to measure self-perception, knowledge, and awareness of halitosis among female university students in Saudi Arabia. Materials and methods A cross-sectional survey was implemented with 392 volunteer participants who responded to a questionnaire on their self-perception, knowledge, and awareness of halitosis. Results The response rate was 89.1% (392/440). Self-perception of halitosis was low (21.4%), whereas a larger percentage (78.1%) indicated noticing people with bad breath. Most participants (80.4%) thought that the gastrointestinal tract is the primary source of halitosis. Seventy-seven percent preferred using personal methods such as mouthwash and chewing gum to treat oral malodor. According to 82.1% of respondents, a dentist is the most appropriate professional to treat halitosis. Conclusion The investigation revealed low self-perception and limited knowledge regarding halitosis. Therefore, the role of dentists in informing and educating their patients concerning oral malodor should be enhanced. Public education about the causes of and possible ways of managing bad breath should be increased. PMID:28603430

The ability to quickly and reliably assess mental health status would assist health workers, educators and youth workers to provide appropriate early intervention for adolescents. To investigate the validity of a simple self perception score out of ten by correlating the self perception scores of adolescents from a normal, community sample of adolescents with their scores on standardized mental health measures. Study group was 470 early adolescent students aged 11.0-14.5 years from grades 7 and 8 in two secondary schools. Self perception was self reported using a score of zero to ten points, and the scores were then correlated with scores on the Harter Self Perception Profile, Beck Junior Depression, Speilberger State and Trait Anxiety and the Eating Disorders Inventory. A High Risk group (self perception adolescents also had poor self esteem and risk for depression, anxiety, and eating disorders. Self perception scores correlated positively with self esteem and self concept subscales and it was negatively associated with depression, state and trait anxiety, and EDI scores. Of the 15.1% high risk adolescents in the overall sample, 78% scored below the group average on the mean of all Harter Self Concept scores; 70% scored above average for Beck Depression; 64% and 74% scored above average on Speilberger State/Trait Anxiety respectively; 80% scored higher than the average on the group mean EDI. A self perception score from zero to ten can be a simple and accurate way of gaining an initial insight into the current mental health status of adolescents.

Weight Suppression Predicts Bulimic Symptoms at 20-year Follow-up: The Mediating Role of Drive for Thinness

Science.gov (United States)

Bodell, Lindsay P.; Brown, Tiffany A.; Keel, Pamela K.

2016-01-01

Weight suppression predicts the onset and maintenance of bulimic syndromes. Despite this finding, no study has examined psychological mechanisms contributing to these associations using a longitudinal design. Given societal pressures to be thin and an actual history of higher weight, it is possible that greater weight suppression contributes to increased fear of gaining weight and preoccupation with being thin, which increase vulnerability to eating disorders. The present study investigated whether greater drive for thinness mediates associations between weight suppression and bulimic symptoms over long-term follow-up. Participants were women (n = 1190) and men (n = 509) who completed self-report surveys in college and 10- and 20- years later. Higher weight suppression at baseline predicted higher bulimic symptoms at 20-year follow-up (p symptoms, body mass index, and drive for thinness. Increased drive for thinness at 10-year follow-up mediated this effect. Findings highlight the long-lasting effect of weight suppression on bulimic symptoms and suggest that preoccupation with thinness may help maintain this association. Future studies would benefit from incorporating other hypothesized consequences of weight suppression, including biological factors, into risk models. PMID:27808544

Uysal, Ahmet; Knee, C Raymond

2012-02-01

Past research has shown that self-handicapping stems from uncertainty about one's ability and self-presentational concerns. The present studies suggest that low dispositional self-control is also associated with self-handicapping. In 3 studies (N = 289), the association between self-control and self-handicapping was tested. Self-control was operationalized as trait self-control, whereas self-handicapping was operationalized as trait self-handicapping in Study 1 (N = 160), self-reported self-handicapping in Study 2 (N = 74), and behavioral self-handicapping in Study 3 (N = 55). In all 3 studies, hierarchical regression analyses revealed that low self-control predicts self-handicapping, independent of self-esteem, self-doubt, social desirability, and gender. © 2012 The Authors.

Research suggests that people with ASD show a diminished (or absent) self-bias in memory and that severity of ASD predicts the extent of this diminution (more severe ASD = smaller self-bias in memory). However, the current research suggests strongly that people with ASD do show a self-bias in their perception. This research informs our understanding of psychological functioning in ASD and challenges theories regarding self-awareness in this disorder. © 2017 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc.

Overvaluation of shape and weight as a mediator between self-esteem and weight bias internalization among patients with binge eating disorder.

Pearl, Rebecca L; White, Marney A; Grilo, Carlos M

2014-04-01

This study aimed to evaluate the roles of self-esteem and overvaluation of shape and weight in accounting for the internalization of weight bias among patients with binge eating disorder (BED) and obesity. Two hundred forty-five treatment-seeking individuals with BED and obesity were evaluated with diagnostic and semi-structured interviews and completed the Weight Bias Internalization Scale (WBIS) and the Rosenberg Self-Esteem Scale (RSE). Correlations and bootstrapping mediation analyses were computed to evaluate the relationships among self-esteem, overvaluation of shape/weight, and weight bias internalization. The effects of body mass index (BMI) and binge-eating frequency were also tested. Significant correlations emerged between WBIS, RSE, and overvaluation of shape and weight. BMI did not correlate with any measure, and binge-eating frequency only correlated with overvaluation. Mediation analyses provided support for the hypothesis that overvaluation of shape and weight mediates the relationship between self-esteem and weight bias internalization. These findings provide support to the proposed model that self-esteem and overvaluation of shape and weight contribute to weight bias internalization among patients with BED, which holds implications for clinical efforts to address weight bias and associated eating and weight-related psychopathology.

Despite the number of weight management programmes and their wide promotion, most overweight and obese individuals tend to lose weight on their own. The present study aimed to understand the characteristics and strategies of those who successfully engage in self-directed weight loss, which could empower other overweight and obese individuals with information and strategies to manage their weight on their own. Men and women who had lost at least 5% of their body weight without direct interaction with professionals or weight management programmes were recruited. Demographic data were collected by questionnaire and participants' weight-loss experiences were explored using semi- structured interviews to elicit in-depth individual experiences and perspectives. Iterative thematic method data analysis was used to generate themes describing contributing factors to the success of self-directed weight loss identified by participants. Most characteristics of those who successfully self-managed their weight loss were in line with those reported by successful weight losers participating in professional-led projects. However, strategies such as early embedding of new lifestyle behaviours into daily routine, the ability to learn from previous weight-loss experiences, and not requiring social support were identified as distinctive factors that contributed to the success of self-directed weight loss by participants of the present study. Overweight or obese individuals with strong internal motivation, problem-solving skills and self-reliance are more likely to be successful at achieving self-directed weight loss. The patients identified with these characteristics could be encouraged to self-manage their weight-loss process, leaving the places available in more resource-intensive professional-led programmes to those individuals unlikely to succeed on their own. © 2017 The British Dietetic Association Ltd.

Purpose: To develop and evaluate the clinical applicability of advanced machine learning models that simultaneously predict multiple optimization objective function weights from patient geometry for intensity-modulated radiation therapy of prostate cancer. Methods: A previously developed inverse optimization method was applied retrospectively to determine optimal objective function weights for 315 treated patients. The authors used an overlap volume ratio (OV) of bladder and rectum for different PTV expansions and overlap volume histogram slopes (OVSR and OVSB for the rectum and bladder, respectively) as explanatory variables that quantify patient geometry. Using the optimal weights as ground truth, the authors trained and applied three prediction models: logistic regression (LR), multinomial logistic regression (MLR), and weighted K-nearest neighbor (KNN). The population average of the optimal objective function weights was also calculated. Results: The OV at 0.4 cm and OVSR at 0.1 cm features were found to be the most predictive of the weights. The authors observed comparable performance (i.e., no statistically significant difference) between LR, MLR, and KNN methodologies, with LR appearing to perform the best. All three machine learning models outperformed the population average by a statistically significant amount over a range of clinical metrics including bladder/rectum V53Gy, bladder/rectum V70Gy, and dose to the bladder, rectum, CTV, and PTV. When comparing the weights directly, the LR model predicted bladder and rectum weights that had, on average, a 73% and 74% relative improvement over the population average weights, respectively. The treatment plans resulting from the LR weights had, on average, a rectum V70Gy that was 35% closer to the clinical plan and a bladder V70Gy that was 29% closer, compared to the population average weights. Similar results were observed for all other clinical metrics. Conclusions: The authors demonstrated that the KNN and MLR

Over the last decade the internet has come to permeate every aspect of our lives. With huge leaps in accessibility of the internet via mobile personal devices such as smart cellular phones and tablets, individuals are connected to the internet virtually all the time. It is no surprise therefore that social media now dominates the lives of many people within society. The authors take a look at how social media is influencing diabetes with particular focus on weight perception, weight management and eating behaviours. The authors explore the concept of how the advertising of Size 0 models and photo-shopping of images which are easily available on line and via social media is causing an increase in the number of young people with distorted body images. This has led to an increased number of people resorting to sometimes drastic weight loss programmes. We focus on the bid for 'low-fat' consumption and highlight how this could actually be leading to an increased risk for developing diabetes or worsening the complications of diabetes. We also discuss the increase of eating disorder in diabetes related to this distorted body image.

Self-perceptions of communicative competence: exploring self-views among first year students in a Mexican university

This research assessed students’ self-perception of communicative competence in EFL in a Mexican university. I argued there was a gap in the knowledge available in the field at the tertiary education level in Mexico that needed filling because of the impact that self-perception has on individuals’ decisions to act, in this case, to engage in communication acts in the foreign language. The objectives guiding my research were: first, to address the information gap; second, to test the scale cre...

Compared to healthy people, patients with chronic kidney disease (CKD) participate less in paid jobs and social activities. The aim of the study was to examine a) the perceived autonomy, self-esteem and labor participation of patients in the pre-dialysis phase, b) pre-dialysis patients' illness perceptions and treatment perceptions, and c) the association of these perceptions with autonomy, self-esteem and labor participation. Patients (N = 109) completed questionnaires at home. Data were analysed using bivariate and multivariate analyses. The results showed that the average autonomy levels were not very high, but the average level of self-esteem was rather high, and that drop out of the labor market already occurs during the pre-dialysis phase. Positive illness and treatment beliefs were associated with higher autonomy and self-esteem levels, but not with employment. Multiple regression analyses revealed that illness and treatment perceptions explained a substantial amount of variance in autonomy (17%) and self-esteem (26%). The perception of less treatment disruption was an important predictor. Patient education on possibilities to combine CKD and its treatment with activities, including paid work, might stimulate positive (realistic) beliefs and prevent or challenge negative beliefs. Interventions focusing on these aspects may assist patients to adjust to CKD, and ultimately prevent unnecessary drop out of the labor market.

Research suggests that making overly positive self-evaluations is the norm rather than the exception. However, unlike other stigmatized groups, overweight individuals do not exhibit a positive in-group social identity and instead exhibit significant explicit, implicit, and internalized weight bias. Therefore, it is not known whether overweight/obese individuals will evidence self-enhancement on general traits (good, attractive), or on traits inconsistent with fat stereotypes (disciplined, active, healthy eater), on an assessment of implicit attitudes. Similarly, it is not known whether these ratings will be associated with preexisting levels of weight bias, gender, or short-term weight loss. At baseline, 53 overweight/obese adults (BMI > 27 kg/m(2), mean BMI = 37.3 kg/m(2), SD = 6.6 kg/m(2), 89% Caucasian, and 77% female) participating in a weight loss intervention completed measures of explicit and internalized weight bias as well as implicit weight bias and identity (self-other comparisons). Although participants evidenced significant anti-fat attitudes, they implicitly identified themselves as significantly thinner, better, more attractive, active, disciplined, and more likely to eat healthy than 'other' people. Compared to men, women were less likely to view themselves as thin and attractive relative to others. Greater implicit anti-fat bias and implicitly seeing the self as thin relative to others was associated with less short-term weight loss. Despite evidence for explicit, implicit, and internalized weight bias, participants generally evidenced a positive implicit self-identity, including areas consistent with negative fat stereotypes.

Nutrition mobile apps have become accessible and popular weight-management tools available to the general public. To date, much of the research has focused on quantitative outcomes with these tools (eg, weight loss); little is known about user experiences and perceptions of these tools when used outside of a research trial environment. Our aim was to understand the experiences and perceptions of adult volunteers who have used publicly available mobile apps to support nutrition behavior change for weight management. We conducted one-on-one semi-structured interviews with individuals who reported using nutrition mobile apps for weight management outside of a research setting. Twenty-four healthy adults (n=19 females, n=5 males) who had used publicly available nutrition mobile apps for weight management for ≥1 week within the past 3 to 4 months were recruited from the community in southern Ontario and Edmonton, Canada, using different methods (eg, social media, posters, and word of mouth). Interviews were audiorecorded, transcribed verbatim, and transcripts were verified against recordings. Data were coded inductively and organized into categories using NVivo, version 10 (QSR International). Participants used nutrition apps for various amounts of time (mean=approximately 14 months). Varied nutrition apps were used; however, MyFitnessPal was the most common. In the interviews, the following four categories of experiences with nutrition apps became apparent: food data entry (database, data entry methods, portion size, and complex foods); accountability, feedback, and progress (goal setting, accountability, monitoring, and feedback); technical and app-related factors; and personal factors (self-motivation, privacy, knowledge, and obsession). Most participants used apps without professional or dietitian support. This work reveals that numerous factors affect use and ongoing adherence to use of nutrition mobile apps. These data are relevant to professionals looking to

Neural correlates of sensory prediction errors in monkeys: evidence for internal models of voluntary self-motion in the cerebellum.

During self-motion, the vestibular system makes essential contributions to postural stability and self-motion perception. To ensure accurate perception and motor control, it is critical to distinguish between vestibular sensory inputs that are the result of externally applied motion (exafference) and that are the result of our own actions (reafference). Indeed, although the vestibular sensors encode vestibular afference and reafference with equal fidelity, neurons at the first central stage of sensory processing selectively encode vestibular exafference. The mechanism underlying this reafferent suppression compares the brain's motor-based expectation of sensory feedback with the actual sensory consequences of voluntary self-motion, effectively computing the sensory prediction error (i.e., exafference). It is generally thought that sensory prediction errors are computed in the cerebellum, yet it has been challenging to explicitly demonstrate this. We have recently addressed this question and found that deep cerebellar nuclei neurons explicitly encode sensory prediction errors during self-motion. Importantly, in everyday life, sensory prediction errors occur in response to changes in the effector or world (muscle strength, load, etc.), as well as in response to externally applied sensory stimulation. Accordingly, we hypothesize that altering the relationship between motor commands and the actual movement parameters will result in the updating in the cerebellum-based computation of exafference. If our hypothesis is correct, under these conditions, neuronal responses should initially be increased--consistent with a sudden increase in the sensory prediction error. Then, over time, as the internal model is updated, response modulation should decrease in parallel with a reduction in sensory prediction error, until vestibular reafference is again suppressed. The finding that the internal model predicting the sensory consequences of motor commands adapts for new

Full Text Available The purpose of the study was to examine the physical self-concept and self-esteem in adolescent girls aged between 13 and 18 years in relation to their body mass status. The Slovenian version of the Self-Description Questionnaire (PSDQ was used to determine the multidimensional physical self-concept among participants. The results indicated that overweight girls reported greater body dissatisfaction in terms self-perceived body fat and physical appearance compared to normal-weight girls. Overweight girls also achieved significantly lower scores in the self-perceived physical abilities, as well as global physical-self and self-esteem than normal-weight peers. As expected, underweight girls reported the lowest amount of body fat. Moreover, they reported lower levels of physical activity than normal-weight peers and had less physical strength compared to the other body mass index categories. The findings has significant implications for the work with adolescent girls in terms of developing appropriate educational intervention and physical education programmes aimed towards reinforcing and increasing self-esteem and promoting active lifestyle.

We define the concept of Dynamic Passive Haptic Feedback (DPHF) for virtual reality by introducing the weight-shifting physical DPHF proxy object Shifty. This concept combines actuators known from active haptics and physical proxies known from passive haptics to construct proxies that automatically adapt their passive haptic feedback. We describe the concept behind our ungrounded weight-shifting DPHF proxy Shifty and the implementation of our prototype. We then investigate how Shifty can, by automatically changing its internal weight distribution, enhance the user's perception of virtual objects interacted with in two experiments. In a first experiment, we show that Shifty can enhance the perception of virtual objects changing in shape, especially in length and thickness. Here, Shifty was shown to increase the user's fun and perceived realism significantly, compared to an equivalent passive haptic proxy. In a second experiment, Shifty is used to pick up virtual objects of different virtual weights. The results show that Shifty enhances the perception of weight and thus the perceived realism by adapting its kinesthetic feedback to the picked-up virtual object. In the same experiment, we additionally show that specific combinations of haptic, visual and auditory feedback during the pick-up interaction help to compensate for visual-haptic mismatch perceived during the shifting process.

Full Text Available Abstract Background Despite the global obesity epidemic, few studies have performed cross-national comparisons of adolescents' attempts to lose weight and weight control practices. This study aims to investigate matters mentioned above by weight status in Europe, Israel, and North America. Methods Nationally representative samples of adolescents from over 30 countries completed an anonymous, standardized questionnaire as part of the Health Behaviour in School-aged Children 2001/2002 survey. The prevalence and likelihood of attempts to lose weight were determined. The effect of weight status, self-perception of overweight, age and country of residence upon the likelihood of current attempts to lose weight were evaluated using multilevel multivariate logistic regression in separate analyses for boys and girls. The study also presented the prevalence of weight control practices of overweight and non-overweight adolescents who had controlled their weight in seven countries. Results In general, overweight and obese adolescents were more likely to be engaged in current attempts to lose weight and had tried to control their weight during the past 12 months more often than non-overweight adolescents. Besides weight status, self-perception of overweight and age were significant individual-level factors determining current attempts to lose weight. Country of residence was a significant second-level factor but no clear geographical pattern was found. Several gender-related differences existed. Conclusion The findings indicated that most overweight adolescents were motivated to reduce their weight. The importance of promoting a healthy body image for all adolescents was highlighted by the fact that self-perception of overweight was found to be the most important factor leading to attempts to lose weight.
