Patients with anorexia nervosa (AN) display elevated anxiety and attention biases (ABs) in threat processing. Attention bias modification treatment (ABMT) is considered promising for anxiety disorders, but its potential for AN is limited. In this study, 154 young women hospitalised because of AN were assigned to ED-related and anxiety-related threat stimuli, or to a non-ABMT intervention control condition in a randomized control trial. Hundred-and-ten patients completed the study. ABMT was an add-on to the regular inpatient treatment. Research participants completed two pretreatment training sessions and eight biweekly sessions of ABMT. AB, ED-related symptoms, depression, anxiety and stress were assessed before and after ABMT in the research groups, and, similarly, 5 weeks apart, in the controls. We found that despite the different patterns of change in AB between the three groups following ABMT, the reduction in AB, or the between-group differences in AB-reduction, were not significant. While the severity of ED-symptoms, depression, anxiety and stress was reduced following ABMT, or control condition, in all groups, there were no between-group differences in these changes. Changes in AB were not correlated with baseline and pre-post-treatment changes in ED-related and comorbid symptomatology. Methodological and inpatient treatment-related considerations may explain our negative ABMT-related results., (© 2022 Eating Disorders Association and John Wiley & Sons Ltd.)

Aim: To examine the prevalence of attention-deficit/hyperactivity disorder (ADHD) and related post-surgical weight loss in adolescents with severe obesity seeking bariatric surgery., Methods: The study population included 84 adolescents (age 13-19 years; 44 males, 40 females) with severe obesity who sought bariatric surgery at the Sheba Medical Centre in Israel during the years 2011-2017. Anthropometric and clinical data were collected from medical records. A subgroup of 20 participants filled questionnaires that evaluated ADHD-like symptoms, eating behaviours and quality of life. Data on adolescents that ultimately underwent surgery (n = 45) were also obtained., Results: The prevalence of ADHD was 28.6% in adolescents seeking bariatric surgery, much higher than that of the general adolescent population of Israel (17.1%, P < .001). There were no significant differences in reductions of weight, body mass index, body mass index standard deviation scores and body fat percent between participants with or without ADHD. In the subgroup that filled questionnaires, higher scores on ADHD-Rating Scale at baseline were associated with greater excess weight loss., Conclusion: The prevalence of ADHD in adolescents seeking bariatric surgery was very high. Diagnosed ADHD was not related to post-surgical weight loss, whereas baseline ADHD-related behaviour was associated with higher post-surgical weight loss., (© 2019 Foundation Acta Paediatrica.

Objective: Strong relationships exist between obsessive-compulsive (OC) disorder and eating disorders (EDs). The aim of the study was to investigate whether OC symptoms would be expressed differently in different ED types., Method: Ninety-four female adolescent inpatients with restricting anorexia nervosa (AN-R), 67 with binge/purge AN (AN-B/P), and 48 with bulimia nervosa (BN) were assessed on admission and discharge using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Yale-Brown-Cornell Eating Disorders Scale (YBC-EDS), Eating Attitude Test-26 (EAT-26), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI)., Results: On admission, patients with AN-B/P exhibited higher scores on the Y-BOCS, YBC-EDS, EAT-26, and BDI in comparison with patients with AN-R or BN. A significant improvement on all psychometric variables from admission to discharge was found for all participants taken together. Nonetheless, patients with AN-B/P and/or BN showed a greater improvement on Y-BOCS, BDI, and STAI than patients with AN-R, whereas no between-group difference was found for YBC-EDS and EAT-26., Conclusions: Obsessionality is more severe in acutely ill AN-B/P patients than in patients with AN-R and BN, whereas a greater improvement in obsessionality from the acutely ill to the stabilized ED condition is found in patients with binge/purge in comparison with restrictive pathology., (© 2018 John Wiley & Sons, Ltd and Eating Disorders Association.)

Patients with anorexia nervosa (AN) have been shown to display both elevated anxiety and attentional biases in threat processing. In this study, we compared threat-related attention patterns of patients with AN restricting type (AN-R; n = 32), AN binge/purge type (AN-B/P; n = 23), and healthy controls (n = 19). A dot-probe task with either eating disorder-related or general and social anxiety-related words was used to measure attention patterns. Severity of eating disorder symptoms, depression, anxiety, and stress were also assessed. Patients with AN-R showed vigilance to both types of threat words, whereas patients with AN-B/P showed avoidance of both threat types. Healthy control participants did not show any attention bias. Attention bias was not associated with any of the demographic, clinical, and psychometric parameters introduced. These findings suggest that there are differential patterns of attention allocation in patients with AN-R and AN-B/P. More research is needed to identify what causes/underlies these differential patterns., (Copyright © 2018 John Wiley & Sons, Ltd and Eating Disorders Association.)
