Brief summary

The research aimed to develop and examine the efficacy of a selective prevention program consisting of eight sessions of online self-help which targeted clinical perfectionism. A randomised controlled trial involving 94 females without eating disorders aged 14 to 19 years was conducted. Participants were randomised into one of three groups: online cognitive behaviour therapy (CBT) for perfectionism (CBT-P), online CBT for nonspecific stress management (CBT-S) or waitlist control. CBT-P resulted in large reductions in clinical perfectionism (CPQ Factor 1 [Perfectionistic Strivings] and CPQ Factor 2 [Perfectionistic Concerns]), moderate decreases in eating disorder, anxiety and depressive symptoms, and large increases in self-esteem, with changes maintained at 6 month follow- up. Changes in clinical perfectionism, eating disorder symptoms, depressive symptoms, anxiety symptoms and self-esteem were significantly larger in CBT-P than CBT-S and waitlist control. Some clinically significant prevention effects were found, with CBT-P being superior to CBT-S in preventing deterioration of clinical perfectionism (CPQ Factor 2 [Perfectionistic Concerns]), and depressive symptoms, and CBT-P being superior to waitlist control in preventing deterioration of eating disorder symptoms over 6-month follow-up. The findings support the notion of clinical perfectionism as a transdiagnostic process and suggest that it may be a useful target for prevention of eating disorders in female youth. The use of technology to promote and engage young women in prevention programs are increasingly popular and accessible, suggesting that online programs may be useful for the prevention of eating disorders, particularly in a stepped care model.

Interventions

The present study aims to examine the effectiveness of an online prevention program for eating disorders which addresses clinical perfectionism. The proposed study is a Randomised Controlled Trial (RCT) targeting female adolescents aged 14 to 19 years old. Participants will be randomized into one of three groups (online guided self-help cognitive behaviour therapy for perfectionism [CBT-P], online guided self-help cognitive behaviour therapy for nonspecific stress management [CBT-S] or waitlist

The present study aims to examine the effectiveness of an online prevention program for eating disorders which addresses clinical perfectionism. The proposed study is a Randomised Controlled Trial (RCT) targeting female adolescents aged 14 to 19 years old. Participants will be randomized into one of three groups (online guided self-help cognitive behaviour therapy for perfectionism [CBT-P], online guided self-help cognitive behaviour therapy for nonspecific stress management [CBT-S] or waitlist control [WLC]). The intervention is CBT-P, which is based on an empirically supported and theoretically driven material “Overcoming Perfectionism: A self help guide using cognitive behavioural techniques” (Shafran, Egan & Wade, 2010). CBT-P consists of 8 sessions that are completed over 4 weeks (2 sessions per week) with each session taking approximately 30minutes to 1hour. To monitor adherence to the intervention, participants are sent a generic weekly sms reminders to log in to the program "Hi (name), please login this week to the beyoutiful program to complete sessions x and y (session number). Thank you!". Participants who have not provided a mobile phone number will be contacted via email. If unresponsive, participants will be contacted by the phone number they have provided on their consent forms.

Inclusion criteria

Inclusion criteria are: 1. Female, 14-19 years old 2. Internet access either at home or at a location where regular use is possible (e.g. school, library) 3. Adequate English language skills 4. Access to a General Practitioner who would be able to monitor their physical health (in the event that they are at risk of suicidality/eating disorder symptoms, anxiety or depressive symptoms, we recommend them and their caregivers to seek further help at their GP 5. Body Mass Index (BMI) above or equal to 17kg/m2. It is not necessary for participants to have any symptoms/characteristics of perfectionism to be eligible. Anyone who is interested in participating and meets the inclusion criteria are welcome to join.

Exclusion criteria

1. Currently undergoing psychological therapy 2. Current diagnosis of a clinical Eating Disorder Adolescents who express an interest in participating in the study will be screened for eating disorders using the SCOFF questionnaire (Morgan, Reid, & Lacey, 1999), suicidality using the B1 suicidality module of Mini International Neuropsychiatric Interview Kid (MINI-Kid; Sheehan et al., 1998). Interested adolescents cannot endorse two or more items on the SCOFF. Adolescents who endorse two or more items will be excluded from the study. They/their caregivers (if under 18) will be notified and advised to bring their adolescent to their local GP for a full assessment. The SCOFF is a screening tool for eating disorders with five questions addressing the core features of Anorexia Nervosa and Bulimia Nervosa. Interested adolescents cannot endorse any of the three questions on the B1 suicidality module on the MINI-Kid in the past 28 days. If they do, they/their caregivers (if under 18) will be notified and advised to bring their adolescent to their local GP for a full assessment and they are excluded from the study.
