A consultation with genetic information about obesity decreases self-blame about eating and leads to realistic weight loss goals in obese individuals.

OBJECTIVE: This study tested the effects of a consultation using genetic information about obesity on attitudes relating to weight loss goals, self-blame about eating, and weight-related coping in obese individuals. Furthermore, the study sought to explore possible predictors for weight gain/loss. METHOD: A total of 411 obese individuals were randomly assigned to two standardized consultations, with and without genetic information about obesity, and a control group without any intervention. After a 6-month follow-up, 253 obese individuals of the intervention groups and 98 individuals of the control group had a complete dataset. Data were analyzed regarding the independent variables assessment time, treatment group, and the familial predisposition (at least one obese parent or sibling). As dependent measures, attitudes about weight loss goals, weight-related self-blame, coping, and body shame were assessed via questionnaire or interview. RESULTS: Individuals with and without a familial predisposition profited in different ways from a consultation using genetic information about obesity: at follow-up, individuals with a familial predisposition reported mainly a relieving effect (less self-blame about eating). Both groups reported an adjustment to more realistic weight loss goals and a greater satisfaction with a 5% weight loss. Furthermore, the more negative obese individuals felt about their current weight at baseline, the higher the risk that these individuals had gained weight at follow-up. CONCLUSION: A consultation focusing on genetic factors might be helpful for obese individuals regardless of their familial predisposition, but only predisposed individuals showed a decrease in self-blame about eating. Negative thoughts and feelings about current weight might predict future weight gain.

Causal attributions of obese men and women in genetic testing: implications of genetic/biological attributions.

The present study sought to investigate genetic/biological attributions of obesity, their associations with a predisposition to obesity and their crossectional and longitudinal implications for weight regulation in obese individuals presenting for genetic testing and counselling. A total of 421 obese men and women underwent psychological and anthropometric assessment and a mutation screen of the melanocortin-4 receptor gene. At study entry, women revealed more genetic/biological attributions than men on the Revised Illness Perception Questionnaire adapted to obesity (86.2% versus 59.7%). Genetic/biological attributions of obesity were associated in both sexes with a family history of obesity, assessed through Stunkard's Figure Rating Scale. In both sexes, genetic/biological attributions were unrelated to weight regulation beliefs and behaviour (i.e. self-efficacy, controllability beliefs, restrained eating and physical activity), assessed through standardised questionnaires or interview at baseline and at six-month follow-up. In addition, causal attributions and weight regulation beliefs and behaviour were not predictive of body mass index at six-month follow-up. Overall, the results indicate that causal attributions of obesity to genetic/biological factors in obese individuals presenting for genetic screening and counselling are crossectionally and longitudinally unrelated to weight regulation and longer-term weight outcome. Those who attribute their obesity to genetic/biological factors likely have a familial obesity risk.

Who copes well? Obesity-related coping and its associations with shame, guilt, and weight loss.

The relationship among weight-related coping, guilt, and shame was investigated in a sample of 98 obese German individuals over a 6-month period. In terms of the objectives, the study explored the kind and frequency of typical coping situations in which obese individuals become aware of being obese. Furthermore, the study sought to determine the predictive utility of weight-related shame and guilt concerning coping responses, and to establish whether there is an association between coping responses and weight change. A longitudinal examination over a 6-month period was chosen with two measurement points. As typical distressing coping situations, individuals reported mostly negative evaluations through others/self, physical exercise situations, or environmental hazards (mainly shopping for clothes). Weight-related shame at baseline was a significant negative predictor for problem-focused engagement coping, whereas weight-related guilt was a significant positive predictor for problem-focused engagement strategies and dietary restraint at follow-up. Although Body Mass Index showed no substantial association with the coping measures, weight loss was accompanied by a substantial drop in problem-focused disengagement coping (wishful thinking, problem avoidance). Discussion of these findings focuses on the issue of possible effects of weight-related feelings of guilt and shame on coping behavior, the link between weight loss and disengaging coping strategies, and the possible use of the findings for cognitive-behavioral therapy for obesity.

Is information on genetic determinants of obesity helpful or harmful for obese people?--A randomized clinical trial.

BACKGROUND AND OBJECTIVES: Although more and more genetic information is available, it is unclear whether this information is helpful for patients. Therefore, we assessed the positive and negative effects of informing obese people about the genetic etiology of being overweight. DESIGN, PARTICIPANTS: Two hundred ninety-four obese people were randomized to 2 interventions (a 1-session consultation for obese people on how to manage obesity either including genetic information or not); their results were compared to a control group (116). Subjects were assessed before and after consultation and 6 months later. MEASUREMENTS: Weight, scales on feeling guilty for being overweight, self-control, negative mood (primary endpoint), body acceptance, restraint eating. RESULTS: Both types of consultations were considered helpful by the participants, and had comparable effects on body weight. The consultation with genetic information was rated superior in terms of leading to new insights (advantage for consultation with genetic information, even 6 months later; p = 0.046). No negative effects (e.g., loss of self-efficacy/self-control, increase of body weight; all p > 0.20 for interaction consultation x time) were observed for informing obese people about the genetic etiology of being overweight. The consultation resulted in long-term improvement of negative mood if it included genetic information in the case of participants with a family history of obesity and if it included no genetic information in the case of obese people without a family history of obesity (p = 0.03 for interaction of group, intervention, and time). CONCLUSIONS: Consultations in obesity can be helpful in general. These consultations should include genetic information if people have a family history of obesity.

Development of the Weight- and Body-Related Shame and Guilt scale (WEB-SG) in a nonclinical sample of obese individuals.

In this article, we present the evaluation of the psychometric properties of a new self-report measure of Weight- and Body-Related Shame and Guilt (WEB-SG). The main purpose of the study was to measure shame and guilt feelings separately in obese individuals and investigate differing behavioral and emotional correlates of these emotions. Altogether, 331 obese participants completed the WEB-SG and other established self-report measures. A subset of the participants completed a 6-month follow-up. The WEB-SG proved to be internally consistent and temporally stable over a 6-month period. Regarding the factorial structure, a two-factor conceptualization was supported. The construct validity of the WEB-SG subscales was evidenced by a substantial overlap of common variance with related measures. The subscales Shame and Guilt showed differential correlation patterns to other scales. The WEB-SG is a brief, psychometrically sound measure for assessing body shame and guilt concerning weight control in obese individuals.

What determines well-being in obesity? Associations with BMI, social skills, and social support.

OBJECTIVE: Theory and research suggest that the stigma associated with obesity has an impact on the development of social skills and social relationships which may be related to subjective well-being. The main objective was to clarify the associations between BMI (kg/m2), social skills, social support and subjective well-being in a sample of obese subjects. METHODS: Cross-sectional study of 226 obese adults (75 females and 151 males) from the general population between the ages of 19 and 74 [mean (SD), 46.9 (13.7) years]. Mean (SD) BMI of the subjects was 36 (5.3). OUTCOME MEASURES: subjective well-being was measured by the Satisfaction With Life Scale (SWLS) and by the Positive And Negative Affect Scales (PANAS). Social support was assessed with scales of the Social Support Questionnaire F-SozU and social skills with a short form of the German Insecurity Questionnaire U-24. RESULTS: Hierarchical regression analysis showed that social support and social skill measures are relevant predictors of subjective well-being (with both independent and shared influences), while BMI is not. The obese people in our study neither differed from other comparison groups in their subjective well-being, nor did they report greater impairments in social skills or social support. CONCLUSION: BMI does not seem to be the major determinant of low subjective well-being in obesity. As in healthy controls, subjective well-being is principally associated with social skills and social support.
