• Conditions: Type 1 Diabetes Mellitus; Type 2 Diabetes Mellitus (T2DM)

• Registration Number: NCT07051005
• Lead Sponsor: Canterbury Christ Church University

Brief Summary

The goal of this clinical trial is to examine the feasibility and acceptability of an online programme that is based on Compassionate Mind Training (CMT) over four-weeks. The programme intends to share information and strategies to reduce diabetes distress, self-criticism, and shame, and improve physical health in people who have Type 1 and Type 2 Diabetes Mellitus.

Detailed Description

This pilot randomised controlled trial seeks to examine the feasibility and acceptability of online compassion training tailored for adults living with Type 1 and Type 2 diabetes. Participants will be randomised to either the compassion training course or a waitlist control group, in which participants will be offered the intervention at the end of the study. Four self-report measures will be administered online at baseline (weeks 0-1) and post-intervention (weeks 9-10). The indices of feasibility and acceptability that will be examined include: 1. ease of recruitment; 2. participant retention in the intervention; 3. participant retention in the study; 4. acceptability of the intervention; 5. outcome measure completion; 6. whether there is a preliminary signal of efficacy on the primary outcome measure (diabetes distress). These indices will be compared to progression criteria which determine whether the intervention is sufficiently feasible and acceptable to progress to a full-scale RCT in future research.

Primary Outcome Measures

Name	Time	Method
Number of participants recruited	6 months following the start of recruitment	The number of participants recruited over 6-months will be compared against the following progression criterion to assess the feasibility of recruitment: Green: 40-50; Amber 24-39; Red: \<24.
Proportion of study participants who remain in the study	Weeks 0 to 10	The proportion of study participants who remain in the study will be compared against the following progression criterion to assess retention in the study: Green: ≥50%; Amber 25-49%; Red: \<25%.
Estimate of between group effect size of the compassion training course intervention compared to control on the primary outcome measure of change in Diabetes Distress Scale scores from baseline (weeks 0-1) to post-intervention (weeks 9 - 10).	Weeks 9 - 10	The estimated between group effect size of the compassion training intervention compared to control on the primary outcome measure of change in Diabetes Distress Scale scores from baseline (weeks 0-1) to post-intervention (weeks 9-10) will be compared against the following progression criterion to provide a preliminary indicator of effectiveness: Green: effect size in favour of intervention arm and 95% confidence interval for that effect size contains (or is greater than) the minimal clinically important difference (MCID) found in previous research (0.25 or greater). Amber: effect size is in favour of control, but the minimum clinically important difference is included in the 95% confidence interval; Red: effect size is in favour of control, and the minimum clinically important difference is not included in the 95% confidence interval.
Proportion of intervention group participants who complete at least half of the compassion training course intervention sessions	Weeks 2 to 8	The proportion of participants who completed at least half of the intervention sessions will be compared against the following progression criterion to assess retention in the intervention: Green: ≥50%; Amber 25-49%; Red: \<25%.
Compassion training course acceptability	Weeks 9 to 10	Response to Likert type questions and content analysis of qualitative data will be compared against the following progression criterion to assess retention in the study: Green: the majority of intervention participants report the intervention is acceptable as it is or with minor adjustments; Amber: there are inconsistent reports of acceptability or the intervention requires bigger adjustments; Red: the majority of intervention participants report the intervention is unacceptable or requires adjustments which cannot be completed.
Completion rate of the outcome measures	Weeks 0 to 10	The rate of the outcome measures completion will be compared against the following progression criterion to assess the feasibility of outcome measure completion: Green: ≥60%; Amber 40-59%; Red: \<40%.

Secondary Outcome Measures

Name	Time	Method
Estimate of the between group effect size of compassion training intervention compared to control on change in the External and Internal Shame Scale (EISS) from baseline (weeks 0-1) to post-intervention (weeks 9-10).	Weeks 9-10	This is an eight-item scale informed by the evolutionary, biopsychosocial model measuring external and internal dimensions of shame. Research shows that individuals with chronic physical health conditions report higher levels of internal and external shame.
Estimate of the between group effect size of compassion training intervention compared to control on change in the Forms of Self-Criticising/ Attacking & Self-Reassuring (FSCRS) Scale from baseline (weeks 0-1) to post-intervention (weeks 9-10).	Weeks 9-10	The FSCRS is a 22-item self-report measure developed to measure self-criticism and the ability to self-reassure. The scale comprises three subscales: Inadequate-Self, which focuses on feelings of personal inadequacy, Hated-Self, measuring the desire to hurt or punish oneself, and Reassured-Self, which is an ability to reassure and support the self.
Estimate of the between group effect size of compassion training intervention compared to control on change in the Compassionate Engagement and Action Scale (CEAS) from baseline (weeks 0-1) to post-intervention (weeks 9-10).	Weeks 9-10	The scale has been validated to measure self-compassion through engagement, by assessing engagement with sensitivity, sympathy, non-judgement, empathy, distress tolerance and caring, and self-compassion through action, by balanced reasoning, focusing attention on helpful contexts, actions that alleviate distress and cultivating inner support to alleviate distress. The 13-item sub-scale within the CEAS will be used (compassion to self).
