Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study is a randomised controlled trial where participants will participate in a brief self-compassion intervention, either starting straight away (intervention group) or starting the following weekend after the intervention group finishes (wait-list control group).

The brief self-compassion intervention will involve two 2.5 hour sessions (one week apart) in groups of 14 participants and will include group activities, meditations and individual reflections. Themes and topics of these activities will include: mindful self-compassion, mindfulness, adolescent brain development and self-esteem vs self-compassion. These activities are taken from the 'Making Friends with Yourself' self-compassion 8-week program for teens teacher manual, with permission given from the developer, Karen Bluth. As per the standardised 8-week program, participants will be given the standardised handout booklet (only including activities that are incorporated in this brief version) and audio recordings of meditations (made available by Karen Bluth's 'Making Friends with Yourself' program). Participants are given examples of situations to use these resources (e.g., mindfulness activities, meditations) and encouraged to try out the different activities to find ones that work well for them.

The sessions will be conducted at the University of Auckland Grafton Campus, face-to-face. The sessions will be conducted by a trained teacher of the 'Making Friends with Yourself' self-compassion program for teens, who is also a PhD candidate.

Outcomes
Primary outcome [1] 319557 0
Disordered eating behaviour assessed by the Diabetes Eating Problem Survey Revised (DEPS-R; Markowitz et al., 2010).

Baseline and at post-intervention.
Primary outcome [2] 322445 0
Feasibility and acceptability of the brief self-compassion program.
Timepoint [2] 322445 0
Feasibility and acceptability will be assessed throughout the study by: (1) evaluating whether adolescents with T1D are willing to participate in the intervention (i.e. recruitment and uptake), (2) reasons for not wanting to participate, (3) the acceptability of the delivered intervention (assessed via qualitative questions), (4) study attrition rate, and (5) the suitability of outcome measures.

Efficacy
Statistical methods / analysis
Pearsons correlations will be used to explore the relationships between the different outcome measures, demographic characteristics, disease characteristics, and current insulin regimen. An independent samples t-test will be conducted at post-intervention (to compare the intervention group with the waitlist control group, before they start the intervention) and will be our main analysis. This test will test our hypothesis for differences between groups in disordered eating behaviour, diabetes-related distress, stress, self-care behaviours and self-compassion. An independent samples t-test will also be conducted at the 12-week follow-up to assess any possible differences between groups for glycaemic control. An exploratory analysis will also combine post-intervention data from participants in both groups to examine changes from baseline, using a paired samples t-test.

Summary
Brief summary
Adolescents with type 1 diabetes are at an increased risk for developing disordered eating behaviours. Using a pilot randomised controlled trial, we would like to examine the feasibility of a brief self-compassion intervention (two 2-hour sessions) and examine any improvements in disordered eating behaviour, self-compassion, self-care behaviours, diabetes-related distress, stress and glycaemic control four weeks after the intervention. We also plan to measure the prevalence of disordered eating behaviour in the clinic population. At least fifty adolescents will be recruited from the diabetes outpatient clinic at Greenlane Clinical Centre. Once participants have consented/assented to participate they will complete a survey measuring disordered eating behaviours. If they score above the cut-off score they will be invited to participate in the intervention and either be randomised into the intervention group (self-compassion intervention) or the waitlist control group (who will receive the intervention four weeks after the intervention group). The intervention will occur in groups of 10-14 and involve group exercises, meditations and individual reflections to teach teens to be more kind to themselves. Participants will complete questionnaires before the intervention and immediately after. We will also examine baseline glycaemic control (HbA1c) when participants are recruited and three months later at their next clinic appointment.
