Study type
Interventional
Description of intervention(s) / exposure
Internet-based Cognitive Behavioural Therapy for Perfectionism (ICBT-P) is being compared to a waitlist control condition in an online, indicated prevention trial for adolescents displaying at-risk symptoms of eating disorders. Participants will be randomly allocated via computer generated groups to the intervention or waitlist control group. Those in the intervention group will be sent a link and password whereby they can access the ICBT-P modules. The ICBT-P program consists of eight online video/audio and text-based modules based on the Shafran, Egan, and Wade (2018) self-help book. Module 1 defines perfectionism and explores maintaining factors, Module 2 looks at individualised formulations of perfectionism, Module 3 looks at enhancing motivation to change, Module 4 provides psychoeducation, discusses self-monitoring, and survey construction and completion, Module 5 covers behavioural experiments and challenging dichotomous thinking, Module 6 explores unhelpful thinking styles, Module 6 discusses procrastination and time management, and Module 8 covers self-criticism and self-compassion, and relapse prevention. Participants will be encouraged to complete one module every week (approximately no more than 30 minutes), with generic reminder emails being sent to participants over the course of the eight-week program, one per week at the commencement of the week. Participants will also be asked to rate each week how much time they spent on each module, and how many of the activities they completed, to assess fidelity. This is an unguided program, with modules ‘unlocked’ to allow participants to move between them at will. Participants will be requested to complete post-intervention measures after they have completed the eight-week intervention. Links to the follow-up questionnaires will also be sent to them at three- and six-months post-intervention.

Following completion of the study, those in the wait-list control group will have access to the treatment program, in line with the NHMRC chapter 3.1.5, which outlines control groups being ethical and appropriate where participants would otherwise have no recourse treatment that is known to be effective.

Eligibility
Key inclusion criteria
Inclusion criteria are being female and aged 13- to 18-years, having reliable internet access, and reporting elevated symptoms of eating disorder psychopathology [An EDE-Q global score greater than 1.5, as per norms citing a mean EDE-Q global score of 1.5 in a community sample (Fairburn & Beglin, 1994)].
Minimum age
13 Years
Maximum age
18 Years
Sex
Females
Can healthy volunteers participate?
No
Key exclusion criteria
Exclusion criteria are a MINI-Kid score indicating suicidality (module B1), an EDE-Q global score above three (O'Brien et al. (2016) found a mean EDE global score of 3.26 for a clinical paediatric population), and if the participant is currently receiving psychotherapy.

Efficacy
Statistical methods / analysis
An a priori power analyses using G*power (version 3.1.9.2) (Faul, Erdfelder, Lang, & Buchner, 2007), assuming a small effect size, with an adjusted alpha-level of .01 and 80% power indicates that 196 participants (98 per group) is required to adequately power this study. However, if there is difficulty in achieving 98 participants per group, based on previous RCTs conducted by Egan et al. (2014) and Shafran et al. (2017) 40 participants per group would be the minimum required to adequately power this study (based on finding a large effect size [d = .80], with an alpha level of 0.05, and at 80% power). Therefore whilst 196 participants is ideal, the minimum required to still perform the required statistical analyses is an overall sample of 80.

Summary
Brief summary
The aim of this study is to examine the efficacy of an ICBT-P program targeting perfectionism, in a sample of adolescents displaying elevated eating disorder symptoms as an indicated prevention study. It is hypothesised that after completion of the online Overcoming Perfectionism intervention, participants will report significantly fewer eating disorder and perfectionism symptoms than at pre-intervention. It is hypothesised that those in the ICBT-P program will score significantly lower on measures of perfectionism and eating disorder psychopathology when compared to a waitlist control. It is predicted that these results will be maintained at three month and six month follow up.
