Therapist-guided internet-supported cognitive behaviour therapy (ICBT) shows enduring effects for various mental health conditions. Long-term follow-up data confirms significant symptom improvement, suggesting lasting benefits of this treatment approach.
Area of Science:
- Psychiatry
- Psychology
- Digital Health
Background:
- Internet-supported and therapist-guided cognitive behaviour therapy (ICBT) is recognized for short-term efficacy.
- Long-term outcomes of ICBT, particularly beyond two years, require further investigation.
Purpose of the Study:
- To review and meta-analyze the long-term effects of therapist-guided ICBT.
- To assess the enduring impact of ICBT across various psychological conditions.
Main Methods:
- Literature search conducted in PubMed and other databases.
- Meta-analysis of 14 studies with 902 participants and an average 3-year follow-up.
- Inclusion of studies on panic disorder, anxiety disorders, depression, OCD, and more.
Main Results:
- A significant pre-to-follow-up effect size (Hedge's g = 1.52) was observed, though with heterogeneity.
- Average symptom improvement across studies was 50%.
- Short treatment durations (8-15 weeks) were typical.
Conclusions:
- Therapist-supported ICBT likely yields enduring positive effects.
- Further research on long-term outcomes for more conditions and new technologies is recommended.
