NCT06239428

Brief Summary

This clinical study aims to compare the efficacy of an internet-based therapist-guided self-help intervention (named i-TREAT) in reducing eating disorder symptoms in Danish adolescents and adults with Other Specified Feeding or Eating Disorders (OSFED). The study is a randomized controlled trial, comparing the intervention group, receiving i-TREAT, with an active waitlist-control group, receiving online mindfulness material. The investigators hypothesize the intervention group to be superior to the waitlist-control group in terms of 1) reducing eating disorder symptoms and 2) increasing quality of life. The internet-based intervention (i-TREAT) consists of 12 online treatment sessions. It is mainly based on Cognitive Behavior Therapy while inspired by Acceptance and Commitment Therapy. Participants are instructed to complete session-related tasks and receive written feedback from their therapist throughout the treatment. Furthermore, the intervention is also supported by text, illustrations, videos, and a chat function, allowing asynchronous text messaging with the therapist. The treatment courses are expected to run for up to 12 weeks. Participants completing the 12-week waitlist are subsequently offered the i-TREAT intervention. The investigators expect to include 63 participants in each group, who will be recruited through 1) self-referral on the project's website and 2) referral from mental health institutions and doctors.

Outcome Measures

Primary Outcomes (1)

  • Eating Disorder Examination Questionnaire (EDE-Q)

    The Eating Disorder Examination Questionnaire (EDE-Q) is a self-report questionnaire assessing the severity and type of eating disorder symptoms and psychopathology during the preceding 28 days. The current version is designed to generate Diagnostic and Statistical Manual of Mental Disorders (DSM-5) compatible eating disorder diagnoses. Finally, the EDE-Q has an excellent internal consistency reliability (Cronbach's α = .95) and is considered the gold standard for measuring eating disorder psychopathology.

    Baseline (Day 0), mid-treatment (up to six weeks), post-treatment (up to 12 weeks), and follow-up (three months)

Secondary Outcomes (3)

  • SCOFF Questionnaire

    Baseline (Day 0), mid-treatment (up to six weeks), post-treatment (up to 12 weeks), and follow-up (three months)

  • Major Depression Inventory (MDI)

    Baseline (Day 0), mid-treatment (up to six weeks), post-treatment (up to 12 weeks), and follow-up (three months)

  • EuroQol - 5 Dimension - 5 Level (EQ-5D-5L)

    Baseline (Day 0), mid-treatment (up to six weeks), post-treatment (up to 12 weeks), and follow-up (three months)

Study Arms (2)

i-TREAT

EXPERIMENTAL

The intervention in the experimental group is an internet-based therapist-guided self-help program, called i-TREAT. The program consists of 12 online treatment sessions. It is mainly based on Cognitive Behavior Therapy while inspired by Acceptance and Commitment Therapy. Participants are instructed to complete session-related tasks and receive written feedback from their therapist throughout the treatment. Furthermore, the intervention is also supported by text, illustrations, videos, and a chat function, allowing asynchronous text messaging with the therapist. The treatment courses are expected to run for 12 weeks.

Behavioral: i-TREAT

Waitlist-control

ACTIVE COMPARATOR

Participants randomized to the active waitlist-control group gains access to online mindfulness material for 12 weeks, however, using the material is non-mandatory. After completing the waitlist, participants are offered the i-TREAT intervention. The active waitlist was implemented to prevent potential adverse effects of being on a passive waitlist (which currently comes closest to treatment as usual since no other treatment modalities exist for the target group in the Danish psychiatry).

Other: Waitlist
