Enhancing the self-esteem of youth swimmers through coach training: Gender and age effects

Prior research has indicated that improving the behavior of youth sport coaches can enhance the self-esteem of boys age 12–14, particularly for those who begin the season with low self-esteem [Smoll, F. L., Smith, R. E., Barnett, N. P., & Everett, J. J. (1993). Enhancement of children's self-esteem through social support training for youth sport coaches. Journal of Applied Psychology, 78, 602–610]. The purpose of the present study was to extend the literature by testing the efficacy of a psychosocial coach training intervention for enhancing the self-esteem of male and female swimmers aged 7–18 years. Youth ( N=135) and coaches ( N=7) participated in a randomized efficacy trial comparing the effects of a psychosocial coach training intervention to an injury prevention intervention on changes in youth self-esteem over the course of a 7-week swim season. Three waves of data were collected: beginning-of-season (pre-intervention), mid-season, and end-of-season. Longitudinal growth modeling indicated significant variability in initial levels of self-esteem at beginning-of-season, but no significant mean level changes over time. Effects of the experimental intervention were moderated by age, initial level of self-esteem, and gender. Effects of psychosocial coach training were strongest for younger participants, and for girls who started the season with low levels of self-esteem. Training coaches in psychosocial and behavioral principles is an effective way to alter coach behavior and enhance the athlete-coach relational context. Psychosocial coach training is also associated with gains in self-esteem for some, but not all, athletes and may be most important for youth who need it most. Implications for coach training programs are discussed.
