Evaluation of a 20-Month Physical Activity Intervention to Improve Motivational and Affective Outcomes Among Disadvantaged Adult Women.

Grounded in self-determination theory, this study aimed to qualitatively examine women's perception of a set of motivational and affective consequences during and immediately after a physical activity intervention. In total, 11 disadvantaged adult women participated in this 20-month intervention. A total of 102 physical activity sessions based on need-supportive strategies were performed. Six discussion groups, 14 semi-structured interviews, and field notes were used to collect data. A thematic analysis was conducted based on self-determination theory. Findings highlighted that it might be advisable among these disadvantaged women to begin with relatedness-support strategies to increase group cohesion, followed by competence support strategies to increase self-confidence, and, finally, autonomy support strategies to empower women to be physically active. The development of a need-supportive environment in a physical activity intervention may have the potential to achieve motivational and affective consequences, which might promote the empowerment of these disadvantaged women to be physically active.
