Collaborative Implementation Intentions, Individual Implementation Intentions, Information Only Control Condition
Conditions
Brief summary
In a 6-week experimental design, up to 90 adult couples in which one partner has Type 2 Diabetes (T2D) will be randomly assigned to either the collaborative implementation intentions (Collaborative IIs), the Individual Implementation Intentions (Individual IIs) condition, or the control condition. As this is a pilot study, randomization for the experimental groups vs the control groups will occur at a 2:1 ratio. Thus, the experimental conditions will contain up to 36 participants and the control condition will contain up to 18 participants. Adults with T2D who are living with a romantic partner, not meeting current physical activity guidelines but able and willing to begin a new physical activity (PA) routine and their partners will be assessed at baseline, 3 weeks and 6 weeks after the experimental manipulation. Partners will report on their own investment in the patient's goal and patients will report on their own PA self-efficacy. Patient's PA will be measured through self-report, partner report and accelerometers for a week prior to each survey assessment. These specific aims are planned: AIM 1: Determine whether collaborative IIs for patient's PA lead to a greater increase in partner investment in partners of adults with T2D than do individual IIs or control. AIM 2: Determine whether collaborative IIs for patient's PA lead to a greater increase in patient PA self-efficacy in adults with T2D than do individual IIs or control. AIM 3: Determine whether collaborative IIs for patient's PA lead to a greater increase in patient PA in adults with T2D than do individual IIs or control.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Objective Physical Activity via accelerometer | Basline, 6 weeks | Participants will wear Actigraph Accelerometers |
| Self-Reported Physical Activity via IPAQ | Baseline, 3 weeks, 6 weeks | Participants will self-report their physical activity over the past week using the International Physical Activity Questionnaire (IPAQ) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Physical Activity Self-Efficacy via a self efficacy scale | Baseline, 3 weeks, 6 weeks | Physical activity self-efficacy will be measured using the self-efficacy for exercise scale (SEE; Resnick & Jenkins, 2000). This 9-item, self-report scale assesses participant's confidence that they could exercise three times per week for 20 minutes under various circumstances (e.g. you had to exercise alone; you felt tired). Respondents are asked to rate items on a scale from 1, (not at all confident), to 10 (extremely confident). |
| Physical Activity Partner Investment Scale | Baseline, 3 weeks, 6 weeks | The Physical Activity Partner Investment Scale assesses the degree to which the partner in a couple defines the patient engaging in regular physical activity as a shared responsibility as well as the degree to which they are taking action to address barriers to the patient engaging in physical activity . The 9 items selected were modified to be specific to engaging in regular physical activity. Participants are asked to rate their agreement each item on a scale from 1 (strongly disagree) to 7 (strongly agree). Example items include If/when my partner decides to engage in regular physical activity , the responsibility will be his or hers alone., My partner and I are able to have useful discussions about how to engage in regular physical activity . and In the long run, my partner and I are able to work together toward helping one or both of us maintain a regular physical activity routine. |
