Abstract

The current study evaluated the long-term effectiveness of acceptance and commitment therapy (ACT) for promoting exercise behavior in comparison with planning in the form of implementation intentions (forming situational cues and action plans as to when, where, and how to incorporate exercise). We expected both interventions to increase exercise behavior (assessed using the Godin Leisure-Time Exercise Questionnaire; Godin and Shephard 1985) from baseline to 6-months post-intervention, but expected only ACT to also increase exercise enjoyment (assessed using the Physical Activity Enjoyment Scale; Kendzierski and DeCarlo 1991). A total of 32 women, randomized to receive a single session of either ACT training or instructions to form implementation intentions for exercise activities, took part in this study. The participants were contacted by email 6-months following the intervention to determine the amount of self-reported exercise. As expected, exercise amount increased in both groups. Contrary to our expectations, both groups also increased in exercise enjoyment. This study provides initial evidence that exercising can be increased through an ACT intervention. ACT and implementation intentions may both be effective and brief interventions for promoting exercise behavior and exercise-related enjoyment in low-active women. Future research needs to establish the psychosocial and personality factors that lead to the effectiveness of ACT and implementation intentions.
