Facetten der Körperbildstörung: eine differenzielle Analyse des TEK-KJ (Test zur Erfassung der Körperbildstörung bei Kindern und Jugendlichen) zur direkten Messung haptisch-perzeptiver Anteile
Zusammenfassung. Zur Erfassung der haptisch-perzeptiven Komponente der Körperbildstörung – einem Kernkriterium der Essstörungen Anorexia nervosa und Bulimia nervosa – stehen nur sehr wenige gut evaluierte Verfahren zur Verfügung. In der vorliegenden Arbeit werden differenzielle Analysen zum Test zur Erfassung der Körperbildstörung bei Kindern und Jugendlichen (TEK-KJ) anhand einer großen Kinder- und Jugendlichenstichprobe dargestellt und zum ersten Mal Daten für männliche Kinder und Jugendliche ausgewertet. Dies beinhaltet die Prüfung der konvergenten Validität im Vergleich zur Contour Drawing Rating Scale (CDRS) und die Analyse von Unterschieden zwischen Kindern und Jugendlichen verschied…
Emotion regulation in adolescents with anorexia and bulimia nervosa: Differential use of adaptive and maladaptive strategies compared to healthy adolescents
Objective: Adolescents with anorexia (AN) and bulimia nervosa (BN) often struggle with emotion regulation (ER). These difficulties have predominantly been assessed across emotions, without considering adaptive and maladaptive ER separately.We compared adolescents with AN or BN to healthy adolescents (HCs) regarding the adaptive and maladaptive ER of three emotions. Methods: A treatment-seeking sample of 197 adolescents (atypical/full-threshold AN: N = 118, atypical/full-threshold BN: N = 32; HC: N = 47) reported emotion-specific ER with the FEEL-KJ questionnaire. Mixed models were calculated for adaptive and maladaptive ER to assess differences between emotions (anxiety, anger, sadness) and…
Momentary emotion identification in female adolescents with and without anorexia nervosa.
Individuals with anorexia nervosa (AN) often report difficulties in identifying emotions, which have been mostly studied as an alexithymia trait. In a controlled two-day ecological momentary assessment, we studied the influence of time of day and aversive tension on self-reported momentary emotion identification. Analysis on an aggregated level revealed a significant lower mean emotion identification in the AN group. In a mixed model analysis, the AN group showed lower emotion identification than the control group (HC). Both a general and a group effect of time of day were found, indicating that emotion identification improved during the day in HC, whereas a negligible decrease of the emoti…
Prevalence and severity of eating disorders: A comparison of DSM-IV and DSM-5 among German adolescents.
Objective Changes in the DSM-5 eating disorders criteria sought to increase the clarity of the diagnostic categories and to decrease the preponderance of nonspecified eating disorders. The first objective of this study was to analyze how these revisions affect threshold and EDNOS/OSFED eating disorder diagnoses in terms of prevalence, sex ratios, and diagnostic distribution in a student sample. Second, we aimed to compare the impairment levels of participants with a threshold, an EDNOS/OSFED and no diagnosis using both DSM-IV and DSM-5. Method A sample of 1654 7th and 8th grade students completed self-report questionnaires to determine diagnoses and impairment levels in the context of an ea…
Differential Change of Borderline Personality Disorder Traits During Dialectical Behavior Therapy for Adolescents
Despite the expansion of treatment options for adults with borderline personality disorder (BPD), research on treatment options for adolescent BPD is scarce. The aim of this study was to investigate the impact of dialectical behavior therapy for adolescents (DBT-A) on the individual trait level as primary outcome; and the frequency of suicide attempts and nonsuicidal self-injury, self-reported BPD core pathology, and general psychopathology as secondary outcomes. Seventy-two adolescents (aged 12–17 years) with full- or subsyndromal BPD were treated with DBT-A (25 single sessions, 20 sessions of skills training), and 13 patients (18.1%) withdrew during treatment. From baseline to post-treat…
Prevention of eating disorders-Efficacy and cost-benefit of a school-based program ("MaiStep") in a randomized controlled trial (RCT).
Objective Given the severity of eating disorders, effective and easily implementable prevention programs which reduce incidence rates and in addition have health-economic benefits are essential. The majority of research on prevention programs focuses on questionnaire-based efficacy or the reduction of eating disorder symptoms while neglecting the health-economic perspective. By contrast, the present study focuses on both an efficacy analysis considering diagnostic criteria (DSM-5) and on evaluating the cost-benefit of a universal prevention program for eating disorders ("MaiStep"). Method A three-arm randomized controlled trial with baseline, posttreatment and 12-month follow-up was conduct…
The spanish body image state scale: factor structure, reliability and validity in a colombian population
ObjectiveBody image is a construct highly dependent on culture and ethnicity. Furthermore, recent studies reveal that body image is not only a trait, but also a momentary state subject to change in diverse situational contexts. However, cultural influences on momentary body image have not been sufficiently investigated. To assess the influence of Latin American culture on momentary body image and to enable its comparison to Western countries, the Spanish translation of an existing state body image scale such as the Body Image States Scale (BISS) is needed. In addition, the factor structure, reliability and general validity of the Spanish BISS (S-BISS) should be evaluated prior to its applic…
Treating eating disorders in the real world — MaiStep: A skill-based universal prevention for schools
Eating disorders are difficult to treat and often associated with morbidity and mortality. Universal prevention approaches are increasingly focusing on enhancing skills, but few eating disorder programs are available for under-15-year-olds. This study aimed to develop and examine a school-based universal prevention program ('MaiStep') for adolescent boys and girls. A three-arm randomized controlled trial with baseline, post-intervention and 12-month follow-up was conducted with 1654 adolescents (M = 13.35, SD 0.76). 'MaiStep' was delivered by psychologists in the first intervention group (IG1) and teachers in the second intervention group (IG2), and compared to an active control group (ACG)…
