Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
An online Single Session Educational Program (SSEP) delivered by a chabot for waitlisted clients seeking eating disorder treatment.

Participants will be randomised into the intervention group or control group. Participants in the intervention group will have access to a 30-minute online SSEP delivered by a chatbot. This will be accessed through a password protected login on a website. The SSEP is based on the single session intervention described by Fursland et al. (2018).

The SSEP focuses on assessment of eating disorder symptoms and providing psychoeducation to the user. Psychoeducation includes information about starvation syndrome and the maintenance cycle of eating disorders which is conducted through interactive activities and short videos. The aim of the SSEP is to provide short term treatment for participants and offer them information so the participant can gain a deeper understanding of their experiences. Participants will complete the SSEP once and they will have on-going access to a summary of the session and material. Upon completion, the participants in the intervention group will complete a post-intervention survey. Analysis of website analytics will be conducted to monitor adherence to the intervention.

Participants will be assessed at baseline, 2-4-weeks, and 3-4 months post-randomisation (the latter representing when the participant has completed the first in-person session of their eating disorder treatment with a psychologist).
