About

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.

Full description

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.
