Abstract
This study aims to explore the complex and multifaceted relationship between Behavioral Activation and Behavioral Maintenance in sports participation, delving into the underlying mechanisms to provide practical insights into how individuals initiate and sustain engagement in sports activities. Utilizing a combination of convenience sampling and snowball sampling methods, 378 sports participants from over ten provinces and cities in China were selected as survey subjects, and an intermediary model concerning the activation and maintenance of sports participation behavior was constructed. Discriminant validity and mediation effect analyses were conducted using SPSS and AMOS 23.0. The results indicate that Behavioral Activation indirectly influences Behavioral Maintenance through Competence (ad = 0.39), with a 95% confidence interval [0.201, 0.642], excluding 0. Behavioral Activation also indirectly influences Behavioral Maintenance through Autonomy (be = 0.23), with a 95% confidence interval [0.109, 0.421], excluding 0. However, Behavioral Activation indirectly influences Behavioral Maintenance through Relatedness (cf. = 0.09), with a 95% confidence interval [-0.068, 0.336], which includes 0. The study reveals that both Competence and Autonomy significantly mediate the activation and maintenance of sports participation behavior among athletes. However, Relatedness does not play a significant mediating role in the activation and maintenance of sports participation behavior among the participants.
