Deciding to exercise: the role of anticipated regret

Two studies tested (a) whether anticipated regret (AR) qualifies as an additional predictor of intentions to engage in a health-enhancing behaviour (exercise) after variables from the Theory of Planned Behaviour (TPB) and past behaviour have been controlled, and (b) whether a manipulation that induces participants to focus on AR causes stronger intentions to exercise.

Study 1 employed a cross-sectional questionnaire design; Study 2 employed a between-participants experimental design (AR focus vs. no AR focus).

Participants (N = 385) completed standard, multi-item, reliable measures of TPB constructs and AR and also reported their past behaviour (Study 1). Participants in Study 2 (N = 70) completed measures of AR and intention; salience of AR was manipulated by means of item order.

Study 1 showed that even though TPB variables and past behaviour were reliable predictors of intention, and explained 51% of the variance, AR contributed a substantial increment in the variance (5%) even after these predictors had been taken into account. Study 2 showed that participants who were induced to focus on AR prior to intention formation had significantly stronger intentions to exercise compared to controls.

The findings indicate that AR predicts a health-enhancing behaviour (as well as the health-risk behaviours examined in previous research) and that effects of AR are independent of TPB variables and past behaviour. The findings also indicate that a simple and inexpensive manipulation of the salience of AR can be used to promote exercise intentions.
