Predictors and outcomes of sports coaches' athlete-invested contingent self-worth.

Some sports coaches not only invest considerable time and energy in their athletes, but also attach their self-worth to the successes and failures of their athletes. Grounded in Self-Determination Theory, the present study aimed to examine the theoretical predictors and outcomes of such Athlete-Invested Contingent Self-worth (AICS). Results from a cross-sectional study (Study 1; N = 740, Mage = 34.37 years) and an experimental vignette-based study among youth sports coaches (Study 2; N = 318, Mage = 38.94 years) indicated that AICS was positively related to a controlling coaching style and negatively related to a structuring style. Study 1 showed that a perceived evaluative club board was positively related to AICS, and Study 2 further demonstrated that poor performance was negatively associated with AICS and that an evaluative climate was related to AICS through experiences of need frustration. The discussion focuses on the pitfalls of coaches' contingent self-worth for the development of their athletes.
