Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Internet cognitive behaviour therapy for perfectionism (ICBT-P) comprises eight online modules for the treatment of clinical perfectionism delivered via a secure online platform wherever the participant had access to a computer. The modules are available for use in research, and each take about 30 minutes to complete. The intervention was unguided with just reminder emails sent by a university research student once a week. The modules involve reading and answering questions and trying out new ideas in practice in their own lives. In study 1 modules were completed once a week for 3 weeks, in Study 2 modules were completed around twice a week for 4 weeks. Adherence was assessed by accessing website analytics.
Module 1 (defining perfectionism) defines ‘unhelpful perfectionism’ and examines the impact it can have on your life. Module 2 (Your Perfectionism Cycle) identifies persistent perfectionistic behaviours and starts to combat them. Module 3 (Surveys and Experiments) ‘Reality check’: adjusts standards and re-examines beliefs according to others’ experiences with behaviours linked to your perfectionism. Module 4 (New Ways of Thinking) challenges and changes perfectionism related cognitions and moves towards a flexible thinking style. Module 5 (Using Skills for Managing Unhelpful Perfectionism) seeks to overcome procrastination and improve problem solving skills, learning to engage without feeling guilty over ‘wasted time’. Module 6 (Self-criticism or Self-compassion) teaches how to deal with ‘failure’; decreasing self-criticism and increasing self-compassion. Module 7 (Re-examining the way we define our self-worth) examines how you define your self-worth; self-worth is not defined by achievement. Module 8 (Staying Well) involves a brief review, and planning for the future –aspirations and preparing for possible setbacks.

Summary
Brief summary
It has been suggested that guided ICBT-P can substantially decrease perfectionism in low doses (3 or less modules) but appears to only impact secondary outcomes with higher doses of treatment. The current study addressed this question, as well as the best method to promote higher dosage use.
