Abstract
This study aimed to examine the effects of a 7-session Acceptance and Commitment Therapy (ACT) intervention on motivation and participation in physical activity among physically inactive adolescent students. This experimental study, employing a repeated-measures design with a control group, was conducted in Shahroud city. A total of 132 female students aged 13 to 18 were randomly assigned to either the intervention or control group. The intervention group participated in a 7-session ACT program over seven weeks, while the control group received no intervention. Motivation and participation in physical activity were assessed before and after the intervention using the BREQ-2 and PAR-Q questionnaires. Data were analyzed using mixed-design ANOVA in SPSS 21. The findings indicated that the ACT intervention significantly increased intrinsic motivation (effect size: 0.86) and identified regulation (effect size: 0.20) while reducing external regulation (effect size: 0.50) in the intervention group compared to the control group (p < 0.001). Additionally, participation in physical activity significantly increased in the intervention group (effect size: 0.82) (p < 0.001). The use of ACT can help enhance motivation and participation in physical activity among physically inactive adolescent students. Therefore, schools can adopt this approach to promote students' motivation and engagement in physical activities.
