Abstract
Health-promoting behaviors have been shown to co-exist, but it is unknown if decisional balance with regards to one health behavior may predict change in another behavior. The objective of this study was to examine the relationship between benefits (pros) and costs (cons) of fruit and vegetable (FV) intake and physical activity (PA) and behavior over time, both within behaviors and transbehaviorally. This longitudinal study was conducted in multiethnic adults in Hawaii (n = 700; 63% female; mean age = 47 years; mean BMI = 25.9; mean education = 14.5 years, average household income = $45,000/year). Questionnaires assessed PA and FV pros/cons on a 5-point Likert Scale, PA (MET-min/wk), and FV intake (servings/day). Multiple regression was used to examine the relationship between pros/cons for PA and FV intake and behavior at 6- and 12-month follow-up. At baseline, average FV pros were 4.08 (.91), and average FV cons were 1.88 (.90). Average baseline PA pros were 4.07 (.89), and average PA cons were 1.71 (.77). Multiple regressions revealed that baseline FV pros and cons predicted FV intake, FV cons also predicted PA, and PA pros and cons were not predictive of PA or of FV intake. Study findings provide some support for decisional balance as a useful core construct used in leading theories of behavior change. Improving decisional balance for FV intake may have a beneficial effect on FV intake and potentially PA, indicating a potential gateway effect of decisional balance for FV intake on other behaviors.
