Description of intervention(s) / exposure
Participants allocated to the treatment group will be registered as users on the Overcoming Perfectionism intervention program website which delivers an Internet based CBT for perfectionism (ICBT-P; Egan et al., 2014) program. The program consists of eight modules which has previous positive evaluations (A Rozental et al., 2017; Shafran et al., 2017; Wade et al., 2019). The eight modules comprising the program include: (1) understanding perfectionism, (2) your perfectionism cycle, (3) surveys and experiments, (4) new ways of thinking, (5) useful skills for managing unhelpful perfectionism, (6) self-criticism or self-compassion?, (7) re-examining the way we define our self-worth, and (8) staying well: managing unhelpful perfectionism in the long-term. Participants were asked to complete module 1 and were then encouraged to complete as many modules as the liked over 4 weeks. Each module took approximately 30 minutes to complete and addressed specific target areas important in the treatment of perfectionism. Intervention adherence and fidelity is controlled by having set online modules which are delivered to each treatment group participant in an identical fashion. However, the number of modules completed and the order of completion is left entirely to each treatment group participant. No other external assessment is conducted to determine adherence and fidelity or control for how each treatment group participant completes the modules.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After selecting yes to the question "Would you like to proceed with the study and be randomised into treatment or control group?" the participant was randomly allocated to either the Treatment or Control groups using the Randomizer function within the Qualtrics data collection and analysis program. Using this function automates the selection process ensuring complete allocation concealment.

Statistical methods / analysis
A longitudinal designs power analysis (Hedecker, Gibbons, & Waternaux, 1999) was conducted using the between-group effect size previously obtained for depression (Johnson et al., 2019), rather than the larger effect sizes obtained for our primary outcome of perfectionism, to ensure power to detect differences for our secondary outcomes. Assuming three timepoints (adjusting for baseline observations), alpha = .05, power = 0.80, attrition rates of T1 = 25% and T2 = 5%, and d = 0.65, a minimum randomised sample size of 64 was estimated, 32 participants per group.
