简要总结
The purpose of this study is to assess the effectiveness of CBT based online guided self-help intervention for perfectionism at reducing symptoms of perfectionism and Axis I disorders post-treatment and at six-month follow-up.
详细描述
Perfectionism is elevated across, and increases risk for a range of Axis I disorders, as well as having a direct negative effect on day to day function. A growing body of evidence shows that cognitive behavioural therapy (CBT) reduces perfectionism and Axis I disorders, with medium to large effect sizes. Given the increased desire for online interventions to facilitate access to evidence-based therapy, web-based CBT self-help interventions for perfectionism have been designed. Existing interventions have not included personalised guidance which has been shown to improve outcome rates.
The purpose of this study is to assess the effectiveness of CBT based online guided self-help intervention for perfectionism at reducing symptoms of perfectionism and Axis I disorders post-treatment and at six-month follow-up.
A randomised controlled trial method is employed, comparing the treatment arm (online guided self-help) with a waiting list control group. Outcomes are examined at three time points, T1 (baseline), T2 (post-intervention at 12 weeks), T3 (follow-up at 24 weeks). Participants will be recruited through universities, online platforms, and social media, and if eligible will be randomised using an online automatic randomiser.

结局指标
主要结局
Frost Multidimensional Perfectionism Scale (Frost et al., 1990)
时间窗: 6 months
This self-report measure consists of 36 items grouped into six subscales. Participants respond on a five point scale ranging from 1 = "strongly disagree" to 5 = "strongly agree". The measure has been found to be both reliable and valid for use with non-clinical and clinical populations (Frost et al., 1990; Hewitt \& Flett, 1991; Hewitt, Flett, Turnbull-Donovan, \& Mikail, 1991). Participants will be considered eligible for inclusion in the study if they score one standard deviation above published norms on the Concern over Mistakes subscale, i.e. a score of ≥ 29. This measure has been amended to reflect participants experience over the past month allowing us to measure change.
