This study explored the antecedents of enjoyment and intention to continue in youth sports using the social-cognitive model of achievement motivation with the 2 × 2 achievement goal modification. Participants were 327 sports participants between 11 and 15 years of age. Individuals high in incremental beliefs reported greater enjoyment and intention to continue. This was perhaps due to endorsing mastery-approach goals. Individuals relatively high in entity beliefs reported relatively less enjoyment. This was perhaps due to endorsing performance-avoidance goals. These individuals also reported relatively less intention to continue regardless of their achievement goals. Findings could have implications for preventing dropout from youth sports.
