We replicated a 1961 study of stigma in childhood obesity to see what effect this increased prevalence has had on this stigma. Research Methods and Procedures: Participants included 458 5th-and 6th-grade children attending upper-middle and lower-middle income U.S. public schools. Children ranked six drawings of same-sex children with obesity, various disabilities, or no disability ("healthy"), in order of how well they liked each child. Results: Children in both the present and the 1961 study liked the drawing of the obese child least. The obese child was liked significantly less in the present study than in 1961 [Kruskal-Wallis H(1) ϭ 130.53, p Ͻ 0.001]. Girls liked the obese child less than boys did [H(1) ϭ 5.23, p Ͻ 0.02]. Children ranked the healthy child highest and significantly higher than in 1961 [H(1) ϭ 245.40, p Ͻ 0.001]. The difference in liking between the healthy and obese child was currently 40.8% greater than in 1961. Discussion: Stigmatization of obesity by children appears to have increased over the last 40 years.

Ninth grade girls (n = 50) received the peer-led program within the school curriculum. A quasi-experimental design was used to assess changes in ED risk factors preintervention and postintervention compared with waitlist control. Participants were followed through 3-month follow-up. Peer-leader adherence to an intervention manual tailored for this age group was high. The intervention was rated as highly acceptable, with a large proportion of participants reporting that they enjoyed the program and learned and applied new information. Intervention participants exhibited significantly greater pre-post reductions in a majority of risk-factor outcomes compared to waitlist controls. When groups were combined to assess program effects over time there were significant pre-post reductions in a ma...

These stigmatizing experiences can lead to detrimental psychological, physical, and societal consequences and may further perpetuate the increasing prevalence of obesity. A. J. Stunkard was one of the first medical professionals to identify and address the serious ramifications of obesity stigmatization on both individual and societal levels. Throughout the last half-century, Stunkard contributed numerous findings and publications to the field of obesity stigmatization. His work laid the foundation and direction for important areas of current research, such as the cultural influences on weight bias, stigmatization among healthcare professionals, weight stigma among children, and the internalization of weight bias by obese individuals. His contributions have had an important influence on the current directions of these fields.

The relationship between internalized weight bias and psychological functioning was also assessed. Participants were 106 men and women with overweight or obesity enrolled in a treatment outcome study using the Lifestyle Balance Program. Participants completed measures of internalized weight bias, anti-fat attitudes, self-esteem, body image concern, depressive symptoms, anxiety, and stress. Variables were assessed at baseline, post-treatment, and six-month follow-up. Weight bias internalization significantly decreased over the course of treatment. Baseline and follow-up internalized weight bias scores predicted change in body weight. Participants reporting the lowest levels of internalized weight bias at baseline lost nearly twice as much weight as participants reporting the highest levels of internalized weight...

We examined whether there were relationships between factors such as weight stigma, weight bias internalization, appearance evaluation, and fears of negative appearance evaluations, and enjoyment and avoidance of physical activity and sport. Undergraduate students (N = 579) completed a survey assessing demographics, and the variables described above. In hierarchal multivariate regression models, weight stigma (β = −0.16, p < 0.001), appearance evaluation (β = 0.19, p = 0.001), and weight bias internalization (β = −0.19, p = 0.003) were associated with lower enjoyment of physical activity and sport. Weight stigma (β = 0.46, p = 0.001), weight bias internalization (β = 0.42, p = 0.001), and fear of negative appearance evaluations (β = 0.16, p = 0.000) were also significantly associated with the tendency t...

However, it remains unclear how a food addiction model (FAM) explanation for obesity and weight control will affect weight stigma. In two experiments (N = 530 and N = 690), we tested the effect of a food addiction explanation for obesity and weight control on weight stigma. In Experiment 1, participants who received a FAM explanation for weight control and obesity reported lower weight stigma scores (e.g., less dislike of ‘fat people’, and lower personal willpower blame) than those receiving an explanation emphasizing diet and exercise (F(4,525) = 7.675, p = 0.006; and F(4,525) = 5.393, p = 0.021, respectively). In Experiment 2, there was a significant group difference for the dislike of ‘fat people’ stigma measure (F(5,684) = 5.157, p = 0.006), but not for personal willpower weight stigma...

Regression models were used to examine the relative contributions of BD and IWB in accounting for variance in physical and mental QoL impairment.ResultsBD and IWB were highly correlated with bivariate analysis in both women (r = .76) and men (r = .60). In multivariable analysis, IWB was found to be associated with both physical (b = − 1.33, 95% CI − 1.93, − 0.72) and mental (b = − 2.58, 95% CI − 3.45, − 1.72) QoL impairment, whilst BD was not associated with impairment in either physical (b = − 0.29, 95% CI − 0.68, 0.09) or mental (b = − 0.48, 95% CI − 1.03, 0.07) QoL. While levels of both BD and IWB were higher for women than for men, sex did not moderate the association between either BD or IWB and either physical or mental QoL.ConclusionsThe findings support the view that IWB warrants greater attention in interventions seeking to reduce the adverse impact of BD in both women and men and both normal-weight and overweight individuals.

Participants included 8,303 children from 7th to 10th grade in the Health Behavior of School-Aged Children (HBSC) 2009-2010 data set, a large-scale sample in the United States. Several multiple linear regressions (with health outcomes as dependent variables) and multivariate logistic regressions (with being bullied or not as dependent variable) were conducted to investigate the associations between each dependent variable and the following independent variables: relationship with parents, frustration with appearance, and actual and self-perceived weight status. Self-perceived underweight, self-perceived overweight (OW), and frustration with appearance were positively associated with being bullied. Frustration with appearance was a risk fac...

Research is lacking on identifying individual differences that impact willingness to use digital interventions, which may affect patient engagement. Health locus of control, the amount of control an individual believes they have over their own health, may predict willingness to use mobile health (mHealth) applications ('apps') and online trackers. A cross-sectional study (n = 276) was conducted to assess college students' health locus of control beliefs and willingness to use health apps and online trackers. Internal and powerful other health locus of control beliefs predicted willingness to use health apps and online trackers while chance health locus of control beliefs did not.

A total of 261 participants completed the LOCES and the Eating Disorder Examination - Questionnaire (EDE-Q) and were identified as non-clinical or having probable ED symptomatology based on previously used EDE-Q cutoff scores. Results indicated that the LOCES and its subscales were significantly associated with and a significant predictor of global ED pathology and binge episode frequency. The LOCES behavioral subscale appeared to be a stronger predictor of episode frequency compared to other subscales. The ED pathology groups reported significantly higher LOCES scores compared to the non-ED pathology groups. Binary logistic regression analyses revealed that the LOCES was able to accurately distinguish between those with ED pathology and those without ED pathology in the majority of cases.

Methods The SF-12 Physical and Mental Component Summary Scales were used to measure health-related quality of life (HRQoL), and the Eating Disorders Examination Questionnaire (EDE-Q) was used to quantify eating disorder behaviors and cognitions. These self-report forms were completed by undergraduate men and women (n = 709). Results Gender was a significant predictor of mental HRQoL, such that women in this sample reported poorer mental HRQoL than men. Eating disorder cognitions were the strongest predictor of undergraduate students' mental and physical HRQoL, while binge eating negatively predicted their physical HRQoL only. Gender was not found to moderate the associations between eating disorder features and HRQoL, and eating disorder cognitions were found to mediate the association between gender and mental HRQoL such that a proportion of the difference between undergraduate men and women's mental HRQoL was attributable to eating disorder cognitions. Conclusion This study provided further evidence of the significant impact of eating disorder features, particularly eating disorder cognitions, on HRQoL. The finding that gender did not moderate the relationships between eating disorder features and HRQoL indicates the importance of investigating these features in both men and women in future research.

The purpose of this study was to use ecological momentary assessment (EMA) to examine the frequency and correlates of body checking behavior, including its association with body image dissatisfaction and negative affect, in non-clinical women with high body concern. Undergraduate female participants with high body concern (n=22) were assessed five times per day for five days via text messages sent to their smart phones. During each assessment, participants reported the number of times they engaged in eight different body checking behaviors and their current level of negative affect and body dissatisfaction. After aggregation, a total of 3064 body checking behaviors were reported by the sample during the five-day period. All participants reported engaging in body checking at least once per day, with a mean of 27.85 checking behaviors per day. Hierarchical...

The aim of the current study was to assess the Factor structure the CAEBS in an online sample of adults seeking information about mental health services. The CAEBS was administered to a nationwide sample of participants from websites offering classified advertisements for mental health related study participation (n = 312). An Exploratory Factor Analysis (EFA) suggested four factors based on 26 of the items: Beliefs Regarding Therapists' Practices, Attitudes about Mental Health Policy, Negative Personal-Level Attitudes toward EBPs, and Negative Societal-Level Attitudes towards EBPs. In order to increase consumer empowerment within the mental health-care system and develop policies supporting EBP usage, mental health professionals need to increase communication with the public to address...

The current study compares traditional CBT with two augmented versions of CBT; schema therapy, which focuses on early life experiences as pivotal in the history of the eating disorder; and appetite-focused CBT, which emphasises the role of recognising and responding to appetite in binge eating. 112 women with transdiagnostic DSM-IV binge eating were randomized to the three therapies. Therapy consisted of weekly sessions for six months, followed by monthly sessions for six months. Primary outcome was the frequency of binge eating. Secondary and tertiary outcomes were other behavioural and psychological aspects of the eating disorder, and other areas of functioning. No differences among the three therapy groups were found on primary or other outcomes. Across groups, large effect sizes were found for improvement in b...

The present study tested whether the association between weight stigma experiences and disordered eating behaviors (emotional eating, uncontrolled eating, and loss-of-control eating) are mediated by weight bias internalization and psychological distress. Six-hundred and thirty-four undergraduate university students completed an online survey assessing weight stigma, weight bias internalization, psychological distress, disordered eating, along with demographic characteristics (i.e., age, gender, weight status). Statistical analyses found that weight stigma was significantly associated with all measures of disordered eating, and with weight bias internalization and psychological distress. In regression and mediation analyses accounting for age, gender and weight status, weight bias internalization and psychological distress mediated the relationship between weight stigma and disordered eating behavior. Thus, weight bias internalization and psychological distress appear to be important factors underpinning the relationship between weight stigma and disordered eating behaviors, and could be targets for interventions, such as, psychological acceptance and mindfulness therapy, which have been shown to reduce the impact of weight stigma. The evidence for the health consequences resulting from weight stigma is becoming clear. It is important that health and social policy makers are informed of this literature and encouraged develop anti-weight stigma policies for school, work, and medical settings.

In regression and mediation analyses accounting for age, gender and weight status, weight bias internalization and psychological distress mediated the relationship between weight stigma and disordered eating behavior. Thus, weight bias internalization and psychological distress appear to be important factors underpinning the relationship between weight stigma and disordered eating behaviors, and could be targets for interventions, such as, psychological acceptance and mindfulness therapy, which have been shown to reduce the impact of weight stigma. The evidence for the health consequences resulting from weight stigma is becoming clear. It is important that health and social policy makers are informed of this literature and encouraged develop anti-weight stigma policies for school, work, and medical settings.
