Abstract
Background: The current study explored whether higher- (up to 8 modules) versus lower-dose (3 or less modules) unguided internet CBT for perfectionism (ICBT-P) was more effective, and the best method to promote higher dosage. Methods: Two sequential randomized ICBT-P studies were conducted with participants who selfidentified as having difficulties with perfectionism; in the first participants (N=51) received 3-module ICBT-P or wait-list, and in the second participants (N=55) received fixed (asked to complete all 8 modules two per week over 4-weeks) or flexible format (after completing the first psychoeducational module, participants decided how many/in what order they completed the modules). We examined impact on our primary variables, perfectionistic concerns and standards, and secondary outcomes of negative affect, body image flexibility, and self-efficacy. Results: More modules were completed in the higher- (M modules=4.36, SD=3.29) versus lower-dose (M=1.96, SD=1.23) ICBT-P, d = 0.86 (95% CI: 0.39, 1.34). The latter impacted perfectionism but not secondary outcomes; the former impacted all outcomes (except for self-efficacy), and within-group effect size improvements were double in the high- compared to low-dose ICBT-P. There was no difference between the fixed and flexible formats in terms of the number of modules completed or impact. Conclusion: We can offer a patient-centred approach to ICBT-P that is effective, while suggesting completion of more modules can result in larger, more pervasive improvements.
