The primary aim of this feasibility study is to determine if a theory-based lifestyle intervention consisting of telephone counseling is associated with improvements in physical activity and dietary intake.
Goal setting has become an integral part of physical activity and dietary interventions; however, few studies have examined the theoretical constructs that drive goal-setting theory. To address the limitations and gaps in the literature, we designed an 8-week health behavior intervention for a racially and ethnically diverse sample of older adults. The primary aim of this study was to determine whether older adults randomized to a goal-setting intervention for physical activity or fruit and vegetable (F&V) intake would make significant improvements in physical activity or F&V intake. The secondary aim of this study was to determine whether participating in goal-setting interventions was associated with changes in theoretical constructs related to goal-setting. We hypothesized that older adults assigned to the physical activity condition would significantly increase metabolic minutes (MET-minutes) of physical activity from baseline to follow-up and that participants assigned to the F&V intake condition would significantly increase mean servings of F&V. In addition, we hypothesized that mean scores of goal specificity, difficulty, effort, commitment, persistence, barrier self-efficacy, and task self-efficacy would significantly increase from baseline to follow-up for both groups.

|---|---|---|---|
| Physical activity | Experimental | Participants received individual tailored telephone counseling and group-tailored newsletters encouraging leisure time physical activity. Content was based on goal setting theory and decisional balance. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Physical activity | Behavioral | Participants received two individually tailored phone calls and two condition specific newsletters encouraging goal setting and weighing the pros and cons for physical activity. |
| Measure | Description | Time Frame |
|---|---|---|
| Leisure Time Physical Activity | Physical Activity was measured using an adaptation of the Godin Leisure-Time Exercise Questionnaire. Participants reported how many times during an average week they participated in mild (i.e., takes minimal effort), moderate (i.e., increases your heart and breathing rate a little), and strenuous activity (i.e., caused one's heart to beat rapidly) for at least 30 minutes at a time. | 8-weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Goal specificity and difficulty | Goal Specificity and Difficulty. Four items were created for each concept: (1) "The goals I set for number times I will [eat F&V or exercise] in a week are," (2) "the goals I set for the type of [F&V or exercise] I will [eat or do] in a week are," (3) "the goals I set for the [amount or duration] of [F&V or exercise] I get in a week are," and (4) "the goals I set for intensity of my exercise sessions within a week are." |
