NCT04261361

Brief Summary

Objectives: The aim of the study is evaluate the efficacy of a telephone assisted cognitive behavioral therapy for adherence (CBCBT) in type 2 diabetes. Hypothesis: CBCBT will primarily reduce depressive symptoms and improve glycemic control and secondarily, improve adherence and self-care and reduce diabetes-specific distress. Design and subjects: This is a prospective randomized two-armed intervention study. One hundred sixty eight participants will be recruited from five sites covering the following clusters: New Territories East, Kowloon East and Hong Kong West. Intervention: The CBT protocol (Safren et al., 2013) will be used in the intervention. Specific components include: 1) introducing CBT for behavior change, 2) increasing pleasurable activities and mood monitoring, 3) cognitive restructuring, 4) problem-solving in self-care and 5) relaxation training. To maximize accessibility, eight sessions will be delivered face-to-face in group setting and the other four sessions will be delivered by telephone. Three monthly follow-up telephone calls will be made to consolidate treatment gains. Main outcome measures: Primary outcomes include the Beck Depression Inventory and glycemic control. Secondary outcomes include self-care and diabetes-specific distress. Data analysis: Treatment outcomes will be assessed by Repeated Measures ANOVA and also Intention to Treat Analysis. Regression models will be used to estimate effect sizes and associations among variables. Expected results: CBCBT would significantly reduce depressive symptoms and improve glycemic control. With secondary outcomes, CBCBT will improve self-care and reduce diabetes-specific distress.

Outcome Measures

Primary Outcomes (2)

  • Depressive symptoms

    The Beck Depression Inventory (BDI-I) assesses cognitive, behavioral and somatic symptoms of depression.

    Change from baseline through study completion, an average of 24 weeks

  • Glycemic control

    Glycated haemoglobin (HbA1c) is used to measure glycemic control

    Change from baseline through study completion, an average of 24 weeks

Secondary Outcomes (2)

  • The Summary of DM Self-care Activities Questionnaire (SDSCA)

    Change from baseline through study completion, an average of 24 weeks

  • DM-specific distress

    Change from baseline through study completion, an average of 24 weeks

Study Arms (2)

CBCBT intervention

EXPERIMENTAL

1. Adherence counseling 2. Psycho-education package 3. The intervention program consists of three components: 1) eight weekly sessions of face-to-face interventions, 2) four weekly consolidation individual telephone calls and 3) three monthly individual follow-up phone calls.

ACTIVE COMPARATOR

1. Adherence counseling; 2. Psycho-education package; 3. To maintain some control over the contact time, we will give them 4 bi-weekly individual phone calls of about 10 minutes each while the CBCBT intervention group is having their 8 weeks of face-to-face group sessions.

Behavioral: Adherence counselingBehavioral: Psycho-education package

Interventions

8 group CBT sessions and 4 weekly follow-up calls

Also known as: CBT
CBCBT intervention

All participants in both CBCBT and ETAU groups will have one session of Life-Steps, a stand-alone CBCBT intervention designed to improve adherence to medical recommendations and individualized DM self-management goals.

CBCBT interventionenhanced treatment as usual (ETAU)

Printed materials of a DM self-management education program will be delivered to both the CBCBT and ETAU groups.
