Daily measures of sport enjoyment, social interaction, and attendance among female adolescent handball players.

This study investigates how sport enjoyment and the immediate impact of social interactions with peers and coaches influence short-term sport participation among early adolescent female handball players. By using a diary study approach, data from 27 players over 10 practices in 4 weeks (270 measurement points) were collected. The findings revealed that coach controlling use of rewards during practice increased the risk of non-attendance at the subsequent practices, while peer relatedness support after practice increased attendance probability.
