OBJECTIVE: This study aimed to investigate the influence of anticipated emotions on preventive health behaviour if specified at the level of behavioural outcomes. Consistent with predictions from a recently developed model of goal pursuit, we hypothesized that the impact of emotions on effort levels depended on the perceived proximity to the goal. DESIGN: Participants with weight-loss intentions were randomly selected from an Internet panel and completed questionnaires at three points in time, baseline (T1; N= 725), 2 weeks later at T2 (N= 582) and again 2 months later at T3 (N= 528). METHODS: Questionnaires assessed anticipated emotions (at T1) and experienced emotions (at T2) towards goal attainment and non-attainment. Goal proximity, goal desirability, and effort levels in striving for weight loss were assessed at both T1 and T2. Current and target weights were reported at all three assessments. RESULTS: In line with predictions, we found that negative anticipated emotions towards goal non-attainment resulted in increased effort but only if people perceived themselves in close proximity to their goal. Effort, in turn, predicted weight loss and goal achievement. CONCLUSION: The current data bear important practical implications as they identify anticipated emotions as targets of behaviour change interventions aimed to stimulate effort in striving for broad, health-related goals like weight loss.
