This study investigated central markers of processing body stimuli by means of event-related potentials in BN. EEG was recorded from 20 women with BN and 20 matched healthy controls while watching and evaluating underweight, normal and overweight female body pictures. Bulimics evaluated underweight bodies as less unpleasant and overweight bodies as bigger and more arousing. A higher P2 to overweight stimuli occurred in BN only. In contrast to controls, no N2 increase to underweight bodies was observed in BN. P3 was modulated by stimulus category only in healthy controls; late slow waves to underweight bodies were more pronounced in both groups. P2 amplitudes to overweight stimuli were correlated with drive for thinness and body dissatisfaction. We present novel support for altered perceptual and cognitive-affective processing of body images in BN on the subjective and electrophysiological level. (C) 2015 Elsevier B.V.

Design Randomized Controlled Trial (RCT), three-intervention-group design, with two intervention groups and one active control group with a 3-month and 12-month follow-up. Setting A project in nine schools within the state of Rhineland-Palatine, Germany; funded by the Ministry of Health and Social Affairs (MSAGD) and the Ministry of Education, Culture and Research (MBWWK). Participants 1,654 adolescents (female/male: 781/873; mean age: 13.1±0.7; BMI: 20.0±3.5) recruited from randomly selected schools. Interventions The implementation and development of the skills based program was based on a systematic review of 63 scientific articles regarding eating disorder prevention in childhood and adolescence. One intervention group was conducted by psychologists and one by trained teachers. The active control group was performed by trained teachers using a stress and addiction prevention program. Main outcome measures The primary outcome measure was the incidence of partial-syndrome and full-syndrome eating disorders after completion of the program; secondary outcomes included self-reported questionnaires about eating disorder pathology. Results MaiStep did not reveal significant group differences at 3-month follow-up but showed a significant difference between the intervention groups and the active control group for partial anorexia nervosa (CHI²(2)) = 8.74, p = .01**) and partial bulimia nervosa (CHI²(2) = 7.25, p = .02*) at 12-month follow-up. Consistent with the primary outcome, the secondary measures were even more effective in the intervention groups at 12-month follow-up. The subscales of the Eating Disorder Inventory (EDI-2) drive of thinness (F (2, 355) = 3.94, p = .02*) and perfectionism (F (2, 355) = 4.19, p = .01**) and the Body Image Avoidance Questionnaire (BIAQ) (F (2, 525) = 18.79, p = .01**) showed significant differences for the intervention groups and demonstrated the effectiveness of MaiStep. Conclusions MaiStep has shown to be a successful program to prevent eating disorders in adolescents at 13 to 15 years of age. In addition, MaiStep was equally effective when conducted by teachers compared to psychologists suggesting feasibility of implementation in real world settings. Trial registration MaiStep is registered at the German Clinical Trials Register (DRKS00005050).}, language = {de} }
