Internet-guided self-help with or without exposure therapy for phobic and panic disorders

Area of Science:

• Psychiatry
• Psychology
• Digital Health

Background:

• Phobia and panic disorders present accessibility challenges for many patients seeking therapy.
• Internet-delivered, computer-aided self-help interventions offer a scalable solution for managing these conditions.
• These interventions can incorporate therapeutic elements like exposure therapy or be minimal without exposure.

Purpose of the Study:

• To compare the effectiveness of internet-based cognitive behaviour therapy (CBT) self-help with and without exposure instructions for phobia/panic disorders.
• To evaluate treatment outcomes at the end of a 10-week program and at a 1-month follow-up.
• To assess patient satisfaction with the self-help interventions.

Main Methods:

• A randomized controlled trial allocated phobia/panic patients to either self-exposure CBT (FearFighter) or minimal CBT (Managing Anxiety) via the internet.
• Participants received brief phone support from a clinician.
• Outcomes were measured using self-ratings and blinded assessor ratings at 10 weeks and 1-month follow-up.

Main Results:

• Both self-help groups showed improvement over 10 weeks.
• The self-exposure CBT group demonstrated significantly greater improvement on 5 out of 10 measures by the 1-month follow-up.
• Standardized effect sizes confirmed the superiority of self-exposure CBT over minimal CBT at follow-up.

Conclusions:

• Computer-aided CBT self-help delivered online, with brief helpline support, is effective for phobia/panic disorders.
• Including exposure instructions in the self-help program enhances effectiveness at the 1-month follow-up.
• Further analysis is warranted to understand the mechanisms behind the short-term effects of non-exposure-based CBT.
