Goal Setting and Lifestyle

University of Hawaii43 enrolled

Overview

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.

Outcomes

Primary Outcomes

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.

Time frame: 8-weeks

Secondary Outcomes

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."

Time frame: 8-weeks
