Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Summary: This study involves a 3-week intervention period during which participants will listen to audio recordings of brief self-compassion meditations each day. Pre- and post-intervention measures of body dissatisfaction, body appreciation, and psychological wellbeing will be administered via an online survey, and these measures will be administered again 6 weeks after the intervention. The purpose of the study is to investigate whether regular listening to self-compassion meditations decreases body dissatisfaction, increases body appreciation, and improves psychological wellbeing.
Brief name: Self-compassion meditation
Materials: All audio recordings of the self-compassion meditations are freely available at www.self-compassion.org. The specific meditations are: Week 1, Compassionate Body Scan (24 minutes); Week 2, Affectionate Breathing (21 minutes); Week 3: Loving Kindness (20 minutes).
Procedures: Participants randomly allocated to the intervention group following the pre-intervention online survey will be given a commencement date for the intervention period. They will be provided the links to the relevant meditations via email and text reminders each day during the intervention period, and will be asked to listen to the relevant meditation each day.
Who: The research team will send the email and text reminders. The meditation recordings were made by Dr Kristen Neff, a leading expert in self-compassion. It will be up to participants to access and listen to these recordings.
Mode of delivery: Participants will access the recordings online.
Duration and intensity: Participants will listen to the relevant meditation recordings (approximately 20 minutes) once a day for three weeks.
Location: All participants will complete online surveys and listen to audio recordings of the meditations at a location of their choosing, provided they have internet access.
Adherence and fidelity: Participants will receive daily reminders via email and text to access and listen to the recordings. As the recordings are provided by a third party, we will not be able to track adherence. However, in the post-intervention survey we will ask participants to report how often they listened to the recordings.

Comparator / control treatment
A multiple baseline design will be adopted whereby a control group will complete the pre- and post-intervention surveys at the same times as the intervention group. During the intervention period, the control group will not be exposed to the intervention and will be requested not to do anything they would not normally do. However, following the main intervention period and the post-intervention survey, those in the control group will then undergo the same intervention, as it is our ethical responsibility to provide access to the intervention to all participants involved in the study. The control group will commence the intervention immediately after the main intervention group completes the intervention (i.e., 3 weeks after the commencement of the main intervention group). Participants will not be told which group they are in; they will simply be given different commencement dates.

Eligibility
Key inclusion criteria
Participants will be young adults in the Australian general population
Minimum age
18 Years
Maximum age
39 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Individuals with a formal diagnosis of an eating disorder and/or an anxiety disorder are ineligible. The pre-intervention survey will also screen for eating disorder symptoms using the Eating Disorder Examination Questionnaire Short (EDE-QS; Gideon et al., 2016), and anxiety symptoms using the Anxiety subscale of the Depression, Anxiety, and Stress Scale short form (DASS-21; Lovibond & Lovibond, 1995). EDE scores above 15 indicate the possible presence of an eating disorder, therefore individuals with a score above 15 will be excluded. Similarly, anxiety scores above 15 indicate severe or extremely severe anxiety, therefore individuals with scores above 15 will be excluded.

Other design features
This study follows a multiple baseline design whereby all participants will receive the intervention but commence at different times. The main intervention group will receive it first, and the control group will receive it after the main intervention period. See below for further detail:
(a) Participants are randomly assigned to intervention or control group after registering in the study.
(b) All participants complete pre-intervention measures at the starting date.
(c) The intervention group undergoes the self-compassion meditation intervention for a 3 week period while the control group do not do anything they would not usually do.
(c) All participants complete post-intervention measures at the same time, 3 weeks after the commencement of the intervention period for the intervention group.
(d) The control group commences the intervention immediately after the intervention group are finished (i.e., 3 weeks after study commencement).
(e) The main intervention group ONLY complete follow-up measures 6 weeks after concluding their intervention (i.e., 9 weeks after study commencement).

Efficacy
Statistical methods / analysis
A priori sample size estimation using the software G*Power Version 3.1.9.2, assuming at least an 80% chance of detecting a moderate anticipated between-groups effect size (f = .25) at an alpha level of 0.05, suggested that a total sample of N = 98 would be sufficient. The estimation of a small to moderate effect size was based on the effect sizes for mindfulness based intervention examinations reported in previous studies. We are aiming to acquire 120 participants, whilst taking into account an estimated attrition rate of 15% .
A mixed model analysis of variance will be used to assess differences in each of the outcome variables between the intervention and waitlist control groups over time.
