Description of intervention(s) / exposure

Mind-2-Body is an online brief intervention for body image based on five key components of Cognitive Behaviour Therapy (CBT). These five lessons cover learning 1) positive body image strategies (self-compassion, gratitude, body functionality, appreciation, and body neutrality); 2) Mind & body relaxation; 3) Combating problematic body image thoughts; 4) combating problematic body image behaviours; 5) removing negative body image triggers.
The content is delivered via an online browser (podia.com). In this, participants learn strategies via videos, texts, images, mini-lectures delivered by Dr. Mariel Messer and via homework tasks.
This program will take approx 60 minutes to complete. Participants are asked to complete the program in one sitting. Homework tasks will take approximately 90 minutes to complete.
This program is purely self-guided. Website analytics from Podia will provide details on number of participant log ins, time spent on the intervention, and lessons completed.

Secondary outcome [9]

Attitudes to help-seeking via single, study derived items:
"I feel confident to seek help for my binge eating behaviour" 0 = not at all confident, 10 = extremely confident).

"I feel confident to seek help for my body image" 0 = not at all confident, 10 = extremely confident).

"I feel motivated to seek help for my binge eating behaviour" 0 = not at all motivated 10 = extremely motivated).

"I feel motivated to seek help for my body image" 0 = not at all motivated, 10 = extremely motivated).

I am willing to seek help for my binge eating or body image problems

I am willing to complete an online intervention for body image to improve my binge eating behaviour

I would prefer face-to-face treatment delivered by a professional for body image and binge eating compared to completing an online intervention

I believe completing an online intervention for body image could improve my binge eating behaviour

Baseline, 4-weeks and 8-weeks post-intervention

Eligibility

Key inclusion criteria

Inclusion criteria will be deliberately kept broad, given that we want to reach a broad population of individuals wanting to address binge eating behaviour, consistent with previous trials of internet-based programs (e.g., Jacobi et al 2007). The inclusion criteria will be adults aged 18 years or over, who have access to the Internet, and who self-report the presence of recurrent binge eating (eating a large amount of food in a short period, accompanied by sense of loss of control), defined as one episode per every two weeks, on average, over the past three months.

Minimum age

18 Years

Maximum age

Summary

Brief summary

DEAKIN UNIVERSITY HUMAN RESEARCH ETHICS COMMITTEE approved the following study design:
There are two phases to this study.  
Phase 1 will involve all respondents to study advertisements to complete a brief screener to determine their eligibility. Those who meet eligibility criteria will then complete an online questionnaire battery that will ask them about their demographics, eating behaviour, self-esteem, body image, and attitudes and acceptability of online interventions. Participants who complete this questionnaire battery will then be randomly allocated via a computer-generated sequence to one of two conditions (Mind-2-Body or wait-list). Participants allocated to the online program will have access to the content of the program immediately and will be asked to practice the exercises as often as they like, and whenever they feel it would be useful. Mind-2-Body is a single-session program that can be completed via an online platform in about 60 minutes. It consists of 5 lessons designed to help people improve their body image, with each step offering a key exercise grounded in cognitive, behavioral, or mindfulness principles. Participants allocated to the wait-list will be notified that they will have access to the program 8-weeks after baseline. 

Phase 2 will occur at the end of the 4-week intervention phase. For both groups, phase 2 involves completing the baseline questionnaire again 4-weeks after the baseline assessment was completed. This will be to assess for the acceptability and efficacy of Mind-2-Body. Participants allocated to the immediate intervention group will also be asked some brief questions about their experiences with the intervention and will be offered an opportunity to debrief about the study with the Principal Investigator (Dr Messer), either via email or telephone.  All participants will complete a final follow-up survey at 8 weeks from baseline. The entire study is therefore done online, and no face to face contact with participants is required. All participants will be reimbursed $25 for the 4-week post survey, and $25 for the 8-week post-survey.

It is hypothesised that those allocated to the body image intervention will show lower levels of negative body image, lower levels of binge eating and eating disorder psychopathology, higher levels of positive body image (appreciation/functionality, flexibility), self-esteem and mental health, and improved attitudes to help-seeking at 4 and 8 weeks post-intervention compared to the control group.
