Acceptance and Commitment Therapy, Diabetes Distress, Type 2 Diabetes
Conditions
Brief summary
This study is a pilot RCT to examine the feasibility, acceptability and preliminary effectiveness of a 6-week acceptance-based diabetes education programme (ACT-DE) on diabetes distress, self-care efficacy and behaviours of adults with type 2 diabetes in Hong Kong. It is hypothesise that the ACT-DE programme will: * Be acceptable, feasible and beneficial for adults with type 2 diabetes to improve their psychological distress and self-care. * Significantly reduce participants' diabetes distress (primary outcomes), when compared with the usual care (control) group immediately post-intervention; * Significantly improve self-care efficacy, self-care behaviour and psychological flexibility (secondary outcomes) than the control group immediately post-intervention.
Detailed description
Diabetes distress is an aversive feeling and emotional disturbance specific to diabetes, including the burden of daily self-care, worry and guilty feelings, and low satisfaction level with health care professionals. Around 36% of people with type 2 diabetes worldwide suffered from diabetes distress, which is associated with poor self-care performance, low self-efficacy in diabetes management and higher blood glucose levels. Acceptance and Commitment Therapy, one of the mindfulness and acceptance-based interventions, integrated with diabetes education are found to be potentially effective interventions for reducing diabetes distress. Participants who agreed to participate in the study were randomly allocated into the intervention (N=24) and the control group (N=24). Participants in the intervention group received a 6-week group-based acceptance and commitment therapy integrated with diabetes education (ACT-DE). There were five sessions in 6 weeks with 120 minutes per session. The group size were 6. While participants in the control group received one session of diabetes education without any information on acceptance and commitment therapy.
Interventions
BEHAVIORALACT-DE
The acceptance and commitment therapy is a psychological component to cultivate participants' acceptance attitude to diabetes and motivate them for a value-driven persistent diabetes self-management, directed by six psychological processes in the hexagonal model of ACT, including acceptance, cognitive defusion, the present moment, self-as-context, value clarification and committed action.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Diabetes Distress Scale | baseline (T0) and immediate post-intervention (T1) | Diabetes distress was measured by the Chinese 15-item Diabetes Distress Scale (CDDS-15). It consists of 15 items rated on a six-point Likert scale from 1 = 'not a problem' to 6 = 'a serious problem'. A mean item score of 2-2.9 and ≥3.0 indicates moderate and severe distress, respectively. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Diabetes self-management behaviours | baseline (T0) and immediate post-intervention (T1) | was measured by the Chinese version of diabetes self-management activities (C-SDSCA). It has 11-items rated on an eight-point Likert scale from 0 to 7, with higher scores indicating more attention to self-management activities. |
| Diabetes management self-efficacy | baseline (T0) and immediate post intervention (T1) | was measured by the Chinese version of Diabetes Management Self-Efficacy Scale (C-DMSES). The C-DMSES contains 20 items rated on an 11-point Likert scale, in which zero indicates not at all confident, and 10 indicates very confident. |
| Psychological flexibility | baseline (T0) and immediate post-intervention (T1) | was measured by the Chinese version of the Acceptance and Action Questionnaire (AAQ-II Chinese). It contains seven items rated on a seven-point, agreement-based response scale from 1 = 'never true' to 7 = 'always true'. The AAQ-II will be scored by summing all item responses, with higher scale scores indicating a greater psychological inflexibility. |
