Positive affect and physical activity: Testing effects on goal setting, activation, prioritisation, and attainment

Abstract

Objective: The present research tested whether incidental positive affect promotes pursuit of physical activity goals. Four key features of goal pursuit were examined – setting physical activity goals (Study 1), goal activation (Study 2), and goal prioritization and goal attainment (Study 3).

Design: Participants (N_s = 80, 81, and 59, in Studies 1–3, respectively) were randomized to positive affect (joy, hope) or neutral affect (control) conditions in each study.

Main Outcome Measures: Questionnaire measures of goal level, goal commitment, and means selection (Study 1); a lexical decision task indexed goal activation (Study 2), a choice task captured goal prioritization and MET minutes quantified goal attainment (Study 3).

Results: Study 1 showed that positive affect led to a greater number of intended physical activities, and that joy engendered greater willingness to try activities. In Study 2, a positive affect induction led to heightened activation of the physical activity goal compared to the control condition. The joy induction in Study 3 led to greater physical activity, and a trend towards greater goal prioritization.

Conclusion: These findings suggest that positive affect enhances the pursuit of physical activity goals. Implications for health behavior theories and interventions are outlined.

Notes

1. We also collected data concerning the accessibility of temptations and inhibition of temptations by physical activity goals. Consistent with counteractive control theory (Fishbach et al., 2003), we observed no significant effects on temptation. The findings for temptation are not discussed further.
