- The aim of the present study was to assess whether behavioral activation (BA) is an efficacious treatment for decreasing eating disorder symptoms in patients with obesity and binge eating disorder (BED). Ninety-six patients with severe obesity and BED were randomized to either 10 sessions of group BA or wait-list control. The study was conducted at an obesity clinic in a regular hospital setting. The treatment improved some aspects of disordered eating and had a positive effect on depressive symptoms but there was no significant difference between the groups regarding binge eating and most other symptoms. Improved mood but lack of effect on binge eating suggests that dysfunctional eating (including BED) is maintained by other mechanisms than low activation and negative mood. However, future studies need to investigate whether effects of BA on binge eating might emerge later than at post-assessment, as in interpersonal psychotherapy for bulimia nervosa.

Impulsivity, Negative Mood, and Disordered Eating in Obesity
- 2014

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Bariatric surgery is a life-altering procedure that leads to substantial weight loss for most patients with obesity. Psychiatric conditions that may interfere with eating behavior and other behavioral prescriptions after surgery are common. Disordered eating is an established risk factor for inferior weight loss but the effects of negative mood and impulsivity are largely unknown. This thesis aims to investigate the prevalence of and associations between these potential risk factors and eating behavior in bariatric surgery patients.Study I assessed the prevalence of adult Attention Deficits/Hyperactivity Disorder (ADHD) symptoms in bariatric surgery patients. Symptoms of adult ADHD were elevated compared to the normal population and associated with symptoms of disordered eating, anxiety, and depression.Study II investigated whether treatment with Behavioral Activation (BA) could ameliorate binge eating and other symptoms of disordered eating in patients with obesity and Binge Eating Disorder. The results showed that BA was effective in increasing activity levels and improving mood but not in ameliorating binge eating in these patients.Study III was a prospective study on disordered eating, symptoms of depression and anxiety, symptoms of adult ADHD, and alcohol risk consumption before surgery and at follow-up after 12 months. After controlling for age, no variable measured before surgery could predict weight loss after surgery. Disordered eating after surgery was associated with inferior weight loss in men and a subgroup of older female participants.The present thesis concludes that symptoms of adult ADHD are common among bariatric surgery patients and associated with disordered eating. There is no indication that symptoms of adult ADHD are associated with short-term inferior weight loss after surgery. However, adult ADHD may be a risk factor for postsurgical alcohol abuse. The treatment study showed no direct association among activity, mood, and binge eating. BA, while effective in improving mood, was found not to be an effective treatment for BED, at least in the short group format investigated.

- INTRODUCTION:Findings regarding psychological risk factors for low weight loss after bariatric surgery have been inconsistent. The association between gender and weight outcome is unclear while younger age has been consistently shown to be associated with better weight outcome. The aim of this study was to analyze the interactions between gender and age on the one hand and symptoms of disordered eating, depression, adult ADHD and alcohol consumption on the other hand in regard to weight loss after gastric bypass.METHODS:Bariatric surgery patients were recruited and asked to fill out self-report questionnaires regarding behavioral risk factors before and twelve months after surgery. Data from one hundred and twenty-nine patients were analyzed.RESULTS:After controlling for age, no psychological variable measured prior to surgery could predict weight loss after twelve months. After surgery, there was an interaction effect between age, gender and specific eating disorder symptoms. Specifically, loss of control over eating was a risk factor for low weight loss among older, but not among younger, female participants. Symptoms of adult ADHD were associated with elevated alcohol consumption after surgery.DISCUSSION:These results indicate that age and gender may moderate the effects of potential risk factors for inferior weight outcome. This interaction could potentially be one of the reasons behind the mixed findings in this field. Thus, there are important gender differences in the bariatric population that should be considered. The present study is the first to show that symptoms of adult ADHD may not be a risk factor for inferior weight loss but for alcohol risk consumption after gastric bypass.

- In the field of bariatric surgery, research on symptoms of adult attention deficit hyperactivity disorder (ADHD) and their interrelationships with other psychological risk factors such as depression and anxiety is scarce. The symptoms of adult ADHD seem to be common in the obese population, but they are rarely investigated before bariatric surgery. ADHD-related symptoms such as impulsivity have at the same time been identified as potential risk factors for less successful weight loss among bariatric surgery patients. The aims of the current study were to screen for symptoms of adult ADHD and to investigate their relationships with other psychological risk factors. Candidates for bariatric surgery ( = 187) were anonymously screened for symptoms of anxiety, depression, and adult ADHD, in addition to disordered eating patterns, by means of questionnaires. The relations between these symptoms were investigated. In the current sample, 10% of patients screened positively for adult ADHD, and the symptoms of adult ADHD were significantly correlated with those of anxiety, depression, and disordered eating. The results show that adult ADHD is more common in this clinical group than in the general population (4%) and that adult ADHD is associated with disordered eating patterns, depression, and anxiety. Further prospective research, using multivariate analysis, is needed to investigate whether the symptoms of adult ADHD, and their interaction with anxiety, depression, or disordered eating, may possibly constitute a risk factor in terms of difficulties in adhering to the post-surgery regime and its potential unfavorable outcome.

- What is already known about this subjectSymptoms of adult attention deficit hyperactivity disorder (ADHD) are common among people with obesity.Symptoms of ADHD are associated with other impulsive behaviours.Impulsivity can manifest differently in women and men.What this study addsThe prevalence of ADHD symptoms was equal in both sexes in this patient group.ADHD symptoms were associated with hazardous alcohol consumption in men but not in women.It may be important to investigate several comorbid conditions simultaneously instead of a single diagnosis.Eating disorders and adult attention deficit hyperactivity disorder (ADHD), both characterized by deficits in impulse control, are common among bariatric surgery patients. Previous studies in other groups have found gender differences in how symptoms of ADHD and eating disorders manifest as women show more disordered eating and men show more risk consumption of alcohol. In the present study, the association between symptoms of adult ADHD, eating disorders and hazardous alcohol consumption was investigated, while considering gender differences. Self-report questionnaires were obtained from 276 bariatric surgery patients 3–6 months before surgery. The prevalence rates of adult ADHD and binge eating disorder (BED) were 8.6% and 6.3%, respectively, with no evidence of gender difference in the prevalence rates. Hazardous alcohol consumption was reported by a significantly larger portion of men (16.9%) than women (8.6%). There was an association between adult ADHD and both BED and hazardous alcohol consumption. However, symptoms of adult ADHD were associated with hazardous alcohol consumption in men but not in women. Our results suggest gender differences in hazardous alcohol consumption and self-reported symptoms of disordered eating despite similar prevalence rate of BED, but no gender difference in symptoms of adult ADHD. Finally, as the associations between these variables seem to be different in women and men, future

- The aim of the present study was to assess the efficacy and effectiveness of the primary prevention program “Everybody’s Different” among fifth grade school children. Pre and post measurements were made in both the intervention and control groups regarding body image, weight concern, emotional well-being, attitudes and behaviors associated with disordered eating, self-esteem, anxiety, and depression. The study did not result in any significant improvements regarding self-esteem, eating attitudes, or body image. The prevention program does not seem to be effective for children in grade five in its present form. Further research on and development of primary prevention programs is needed.
