Eligibility

Age

12 Years to 64 Years

Inclusion criteria

Inclusion criteria: •    Aged between 16 and 25 years. •    Meet the diagnostic criteria for one of the following eating disorders as defined by the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5; American Psychiatric Association, 2013): o    Anorexia nervosa o    Bulimia nervosa o    Binge eating disorder o    Other specified feeding or eating disorders (OSFED) o    Unspecified feeding or eating disorders •    Sufficient proficiency in the Dutch language to complete the questionnaires. •    Willing and able to provide informed consent.  

Exclusion criteria

Exclusion criteria: Participants will be excluded if they meet any of the following criteria:Presence of acute psychotic symptoms that impede treatment.Current substance use, as identified by the referring clinician.Insufficient proficiency in the Dutch language to participate meaningfully in treatment and assessments.A comorbid diagnosis of post-traumatic stress disorder (PTSD). The presence of PTSD will be assessed using the Clinician-Administered PTSD Scale (CAPS; Boeschoten et al., 2018). This exclusion is based on the following considerations:Recommendations from the multidisciplinary PTSD guidelines (Trimbos Institute, 2017), which advise prioritizing PTSD treatment when comorbid conditions are present.The limited number of treatment sessions available within the IST-ED program; additional Eye Movement Desensitization and Reprocessing (EMDR) sessions are typically required in cases of comorbid PTSD.The need to maintain clarity and consistency in research outcomes, as this study specifically focuses on treatment effects on eating disorder symptoms and maintaining factors.
