Pilot Brief Communal Coping Intervention for Adults With Type 2 Diabetes

The investigators plan to develop a communal coping intervention aimed at instilling a shared appraisal of diabetes and increasing patient-partner collaboration. To that end, the investigators will pilot the first randomized clinical trial of a brief communal coping intervention among couples in which one person has T12

About this study

The investigators will recruit 66 couples in which one person has type 2 diabetes. Power is based on effect sizes from previous couple intervention studies and meta-analyses on primary outcomes. Couples will be randomly assigned to either a communal coping intervention or an attention (diabetes education) control group. All couples will come to the laboratory or meet via zoom, complete a baseline questionnaire assessment (primary and secondary outcomes, mediators) and have a videotaped conversation about how they cope with diabetes. The intervention group will receive the communal coping intervention. Couples in the intervention group will identify 5 collaborative implementation intentions, whereas controls will identify 5 individual implementation intentions. After the in-person session, couples will individually complete a daily diary at the end of the day for 14 consecutive days which focuses on daily communication, mood, and patient self-care. During the first 7 days, the intervention group will receive two text messages per day (morning focus on shared appraisal, evening focus on one of collaborative implementation intentions identified during in-person session). An in-person follow-up interview will take place 6 weeks after the initial session, during which primary outcomes, secondary outcomes, and mediators will be assessed and the videotaped conversation repeated.

Treatment and study plan

Communal Coping Intervention

Behavioral

The components of the intervention were described in the experimental arm.

Primary outcomes

  1. diabetes distress

    Time frame: baseline, 2 weeks, 6 weeks

    change in Type 1 Diabetes Distress Scale (Fisher et al., 2015) from baseline to 6 weeks; higher scores = more distress; range 1-6; also change over ecological momentary assessment period change in Type 1 Diabetes Distress Scale (Fisher et al., 2015) from baseline to 6 weeks; higher scores = more distress; range 1-6; also change over ecological momentary assessment period change in Type 1 Diabetes Distress Scale (Fisher et al., 2015) from baseline to 6 weeks; higher scores = more distress; range 1-6; also change over ecological momentary assessment period

  2. self-management

    Time frame: baseline, 2 weeks, 6 weeks

    change in Summary of Diabetes Self-Care Activities from baseline to 6 weeks; higher score = better self-care; range 1-5; also change over ecological momentary assessment period

Secondary outcomes

  1. depressive symptoms

    Time frame: baseline, 2 weeks, 6 weeks

    change in Center for Epidemiological Depression Scale from baseline to 6 weeks; higher numbers = more depressive symptoms; range = 0 to 30; also change over ecological momentary assessment period

  2. life satisfaction

    Time frame: baseline, 2 weeks, 6 weeks

    change in Diener's life satisfaction scale from baseline to 6 weeks; higher numbers= more life satisfaction; range = 1-7; also change over ecological momentary assessment period

  3. relationship quality

    Time frame: baseline, 2 weeks, 6 weeks

    change in Quality of Marriage Index and intimacy subscale from Personal Assessment of Intimacy in Relationships from baseline to 6 weeks; higher numbers = better; range = 1 to 7; also change over ecological momentary assessment period

Other outcomes

  1. self-reports of communal coping, raters coding of communal coping from videotapes, we-talk from brief interview

    Time frame: baseline, 2 weeks, 6 weeks

    change in communal coping from baseline to 6 weeks; higher = more communal coping; range = 0 to 10; also change over ecological momentary assessment period

  2. emotional, instrumental, informational support, criticism, overprotective behavior

    Time frame: baseline, 2 weeks, 6 weeks

    change in social support and negative social interactions from baseline to 6 weeks; higher numbers = more support or more negative interactions; range = 1-7; also change over ecological momentary assessment period

  3. self-report of diabetes communication, videotaped observations

    Time frame: baseline, 2 weeks, 6 weeks

    change in diabetes communication from baseline to 6 weeks; higher numbers = more communication; range = 0 to 10; also change over ecological momentary assessment period

  4. self-efficacy with diabetes management

    Time frame: baseline, 2 weeks, 6 weeks

    change in self-efficacy subscale from Multidimensional Diabetes Questionnaire from baseline to 6 weeks; higher numbers = greater efficacy; range = 0 to 100%; also change over ecological momentary assessment period
