Inclusion criteria
Inclusion criteria: - Female adolescents between 14.01 and 18.11 years of age - Presence of either a diagnosis of bulimia nervosa (BN), binge eating disorder (BED) or its atypical forms (BN/BED of low frequency and/or limited duration) based on DSM-5 - At least three objective binge eating episodes within the last three months with subjective distress or relevant impairment in psychosocial functioning due to the binge eating episodes - Informed Consent (for underage participants also that of the legal guardian).
Exclusion criteria
Exclusion criteria: - Acute suicidality - Anorexia nervosa - Severe psychopathological abnormalities outside the eating disorder symptoms (mild to moderate comorbidities do not lead to exclusion) - Indication for inpatient treatment (e.g. BN or BED with high frequency of binge eating and purging behavior according to severity classification of DSM-5) - Current eating disorder-specific interventions in concurrent outpatient psychotherapy: therapists will be asked not to conduct eating disorder-specific interventions (e.g., cue exposure, mirror exposure, eating attack-related behavior analysis) with the participant during study participation. - Participant's inability to consent
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Testing the efficacy of the cue-exposure intervention in comparison to the standard intervention: The primary aim is to test the efficacy on eating in the absence of hunger, measured by ad-libitum consumption of typical binge foods immediately after the intervention, one week later as well as three months after the intervention (follow-up, FU). | — |
Secondary
| Measure | Time frame |
|---|---|
| As a secondary objective, efficacy will be assessed on the desire to eat/ craving. The desire to eat will be recorded both before and immediately after the intervention as well as one week after the end of treatment. The presumed changes should also be shown to be stable at the 3-month-FU. Furthermore, the treatment effect on ED pathology, including the number of objective binge eating episodes and overeating in the last four weeks will be examined. In addition, it will be investigated whether there are meaningful changes regarding body weight and body fat percentage after the intervention and three months after the end of the intervention in the FU. Furthermore, the change in generic response inhibition will be examined. Potential covariates, such as severity of ED pathology and general psychopathology, as well as treatment experiences and expectations are measured. In addition, the feasibility is to be analyzed: The appropriateness of the cue-exposure intervention for the relevant age and disorder group (13-20-year-old adolescents with binge eating-related disorders) will be tested for acceptance, adherence and therapeutic feasibility. | — |
