Internalized weight bias has been previously associated with impairments in eating behaviors, body image, and psychological functioning. The present study explored the psychological correlates and psychometric properties of the Weight Bias Internalization Scale (WBIS) among overweight adults enrolled in a behavioral weight loss program. Questionnaires assessing internalized weight bias, anti-fat attitudes, self-esteem, body image concern, and mood symptoms were administered to 90 obese or overweight men and women between the ages of 21 and 73. Reliability statistics suggested revisions to the WBIS. The resulting 9-item scale was shown to be positively associated with body image concern, depressive symptoms, and stress, and negatively associated with self-esteem. Multiple linear regression models demonstrated that WBIS scores were significant and independent predictors of body image concern, self-esteem, and depressive symptoms. These results support the use of the revised 9-item WBIS in treatment-seeking samples as a reliable and valid measure of internalized weight bias.

OBJECTIVES: Obesity is an increasingly prevalent public health concern, with associated medical comorbidities and impairment in health-related quality of life (HRQoL). Obese women are frequently victims of weight-related discrimination. The HRQoL impairments among obese people could be related to this discrimination and to internalized weight bias. Design We examined the potential moderating role of discrimination (from others) and self-directed (internalized) weight-based discrimination in the association between body mass index (BMI) and HRQoL. METHODS: Eighty-one women (mean age=41.1years; mean BMI=43.40kg/m(2), 97% Caucasian) completed valid and reliable measures of weight bias internalization (weight bias internalization scale), perceived discrimination by others (everyday discrimination scale) and both physical and mental HRQoL (SF-36 Health Survey). Multiple regression analysis was used to test whether internalized weight bias or discrimination moderated the association between BMI and the summary scores for physical and mental HRQoL, controlling for age. RESULTS: Significant associations were found between BMI and discrimination (r=.36, p=.002), between internalized weight bias and both mental (r=.61, p<.001) and physical HRQoL (r=.45, p<.001), and between discrimination and physical HRQoL (r=.29, p=.014). A statistically significant interaction was found between BMI and internalized weight bias (b=-.21, SE=.10, p<0.05) in accounting for the variance in physical HRQoL. CONCLUSIONS: The association between higher BMI and poorer physical HRQoL was found only in individuals reporting high levels of internalized weight bias. Self-discrimination among overweight individuals may be a critical factor in their physical health impairment.

Obesity is a significant public health problem, and sustainable long-term treatments are needed. This study examined a community-based model of weight-loss treatment. Ninety participants were recruited from eight community organizations (mean age: 49.65 years, mean body mass index: 35.80 kg/m(2); 64% female). Treatment groups were randomly assigned to two maintenance conditions: 1) self-help continuing care, or 2) assessment-only. Both received the same initial 20-session group behavioral treatment. Those randomized to continuing care were additionally instructed to meet as self-sustaining groups for 18 months post-treatment. Weight, physiological, behavioral, and psychological outcomes were assessed at baseline, post-treatment, and at six-month and 18-month follow-up. Eighty-seven percent of participants completed treatment. Participant treatment satisfaction and therapist adherence to treatment protocol were high. No group differences or time by group interaction effects emerged. Participants achieved significant weight losses at post-treatment, with no significant weight regain at six-month or 18-month follow-up. Treatment produced sustained changes in waist circumference, cholesterol, triglycerides, high-density lipoprotein, low-density lipoprotein, insulin, eating patterns, physical activity, quality of life, and body image. A community-based treatment program may be an effective form of behavioral-weight-loss treatment for overweight/obese adults. Weight losses, along with physiological and psychological benefits, were sustained over time.

The present study sought to identify patterns and predictors of disclosure of sexual orientation to healthcare providers among lesbian, gay, and bisexual (LGB) adults. METHODS: Respondents were 396 self-identified LGB individuals ages 18-59, recruited from diverse community venues in New York City, with equal numbers of men and women and Whites, Blacks, and Latinos. Respondents were interviewed at baseline and 1-year follow-up. We assessed the relationships among disclosure of sexual orientation, demographic characteristics, health, and minority stress. RESULTS: Rates of nondisclosure to healthcare providers were significantly higher among bisexual men (39.3%) and bisexual women (32.6%) compared with gay men (10%) and lesbians (12.9%). Bivariate and multivariate logistic regression models predicting disclosure of sexual orientation indicated that patient age, level of education, immigration status, medical history, level of internalized homophobia, and degree of connectedness to the LGB community were significant factors, along with sexual identity. Nondisclosure of sexual orientation was related to poorer psychological wellbeing at one year follow-up. CONCLUSION: Our findings suggest that interventions targeting sexual minorities ought to carefully tailor messages to subpopulations. In particular, interventionists and clinicians ought to be mindful of differences between bisexually- and gay/lesbian-identified individuals.
RESUMO
Lesbian, gay, and bisexual (LGB) individuals suffer serious mental health disparities relative to their heterosexual peers, and researchers have linked these disparities to difficult social experiences (e.g., antigay victimization) and internalized biases (e.g., internalized homophobia) that arouse stress. A recent and growing body of evidence suggests that LGB individuals also suffer physical health disparities relative to heterosexuals, ranging from poor general health status to increased risk for cancer and heightened diagnoses of cardiovascular disease, asthma, diabetes, and other chronic conditions. Despite recent advances in this literature, the causes of LGB physical health problems remain relatively opaque. In this article, we review empirical findings related to LGB physical health disparities and argue that such disparities are related to the experience of minority stress-that is, stress caused by experiences with antigay stigma. In light of this minority stress model, we highlight gaps in the current literature and outline five research steps necessary for developing a comprehensive knowledge of the social determinants of LGB physical health.
RESUMO
BACKGROUND: Weight bias is widespread and has numerous harmful consequences. The internalization of weight bias has been associated with significant psychological impairment. Other forms of discrimination, such as racial and anti-gay bias, have been shown to be associated with physical health impairment. However, research has not yet examined whether internalized weight bias is associated with physical as well as psychological impairment in health-related quality of life. METHODS: Participants included 120 treatment-seeking overweight and obese adults (mean body mass index = 35.09; mean age = 48.31; 68% female; 59% mixed or Asian ethnicity). Participants were administered measures of internalized weight bias and physical and mental health-related quality of life, and they were assessed for the presence of chronic medical conditions, use of prescription and non-prescription medications, and current exercise. RESULTS: Internalized weight bias was significantly correlated with health impairment in both physical (r = -.25) and mental (r = -.48) domains. In multivariate analyses controlling for body mass index, age, and other physical health indicators, internalized weight bias significantly and independently predicted impairment in both physical (ß = -.31) and mental (ß = -.47) health. CONCLUSIONS: Internalized weight bias was associated with greater impairment in both the physical and mental domains of health-related quality of life. Internalized weight bias also contributed significantly to the variance in physical and mental health impairment over and above the contributions of BMI, age, and medical comorbidity. Consistent with the association between prejudice and physical health in other minority groups, these findings suggest a link between the effects of internalized weight-based discrimination and physical health. Research is needed on strategies to prevent weight bias and its internalization on both a societal and individual level.
RESUMO
OBJECTIVE: The present study examined the relationship between experiences of discrimination and occurrence of binge eating among overweight and obese persons, a population which has previously shown elevated rates of binge eating. METHODS: Internet-based questionnaires were used to measure frequency and impact of discrimination, binge eating frequency, and emotional eating. RESULTS: Pearson correlation analyses demonstrated significant positive relationships between the measures of discrimination and measures of eating behaviors (r = 0.12-0.37). Regression models significantly predicted between 17 and 33% of the variance of emotional eating scores and frequency of binge eating; discrimination measures contributed significantly and independently to the variance in emotional eating and binge eating. Weight bias internalization was found to be a partial mediator of the relationship between discrimination and eating disturbance. CONCLUSION: Results demonstrate the relationship of discrimination to binge eating. Weight bias internalization may be an important mechanism for this relationship and a potential treatment target.

OBJECTIVE: Widespread bias against obese individuals may lead to the internalization of weight bias in obese persons. This study examined correlates of internalized weight bias (IWB) in obese patients with binge eating disorder (BED). METHOD: One hundred treatment-seeking obese patients with BED were administered with the eating disorders examination interview and questionnaires assessing IWB, fat phobia, depression, and self-esteem. RESULTS: The mean IWB score in this group of patients with BED was significantly greater than the mean IWB score observed previously in a community sample of overweight adults. IWB was positively associated with eating disorder psychopathology, fat phobia, and depression, and negatively associated with self-esteem. IWB made significant independent contributions to the variance in eating disorder psychopathology even after accounting for fat phobia, depression, and self-esteem. DISCUSSION: Treatment-seeking obese patients with BED demonstrate high levels of IWB. IWB may contribute to the variance in eating disorder psychopathology in BED patients, beyond the contributions of fat phobia, depression, and self-esteem.

OBJECTIVE: The present study developed the Weight Bias Internalization Scale (WBIS), an 11-item measure assessing internalized weight bias among the overweight and obese. METHODS AND PROCEDURES: An Internet sample was recruited through online community discussion groups and snowball sampling via e-mail. Women (n = 164) and men (n = 34) with a BMI > 25 kg/m2 completed the WBIS and the Antifat Attitudes Questionnaire (AAQ), as well as measures of self-esteem, body image, mood disturbance, drive for thinness, and binge eating. RESULTS: Results indicate that the WBIS had high internal consistency (Cronbach's alpha = 0.90) and correlated significantly with antifat attitudes but was not a completely overlapping construct (r = 0.31). The scale showed strong partial correlations with self-esteem (r = -0.67), drive for thinness (r = 0.47), and body image concern (r = 0.75), controlling for BMI. Internalized weight bias was also significantly correlated with measures of mood and eating disturbance. Multiple regression analyses were conducted using WBIS scores, antifat attitudes, and BMI as predictor variables of body image, mood, self-esteem, and binge eating. WBIS scores were found to significantly predict scores on each of these measures. DISCUSSION: The WBIS showed excellent psychometric properties and construct validity. The study highlights the importance of distinguishing antifat attitudes toward others from internalized weight bias, a construct that may be closely linked with psychopathology.
