    • Perfectionism is an important transdiagnostic risk factor for several psychopathologies. As such, treatments targeting perfectionism have gained increased attention over recent years. While perfectionism is postulated to be an important underlying mechanism for dysmorphic concern, no research has explored the benefits of targeting perfectionism to reduce dysmorphic concern. The current study evaluated the use of Internet-delivered cognitive behavioural therapy for perfectionism (ICBT-P) with 31 participants (28 women) with high levels of dysmorphic concern to examine the impact on perfectionism, dysmorphic concern, body image disturbance, negative affect, and selective attention towards appearance-based stimuli. Using a case series design, observations were collected at baseline, at the end of a 4-week pre-treatment phase, after the 8-week ICBT-P, and 1-month post-treatment. Intent-to-treat analyses showed significant improvement from baseline to end-of-treatment and follow-up on most of the variables, with a large effect size decrease in dysmorphic concern, and decreased selective attention to BDD-body, BDD-positive, and BDD-negative words. The results of this study support the use of ICBT-P as an efficacious treatment worthy of further examination in populations who experience high levels of dysmorphic concern.

  • Internet-based cognitive behaviour therapy for perfectionism : More is better but no need to be prescriptive

    • Background: The current study explored whether higher- (up to 8 modules) versus lower-dose (3 or less modules) unguided internet Cognitive Behaviour Therapy for perfectionism (ICBT-P) was more effective, and the best method to promote higher dosage.Methods: Two sequential randomised ICBT-P studies were conducted with participants who self-identified 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% confidence interval: 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.Conclusions: 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.ANZCTR Trial Number: ACTRN12619000147189.
