This study examined group differences among interscholastic sport participants (i.e., starters, nonstarters, and survivors) on several psychological constructs. Specifically, achievement goal orientations, perceived ability, and costs/benefits of involvement were examined over the course of an interscholastic sport season. Athletes (N=249) responded to an Interscholastic Sport Questionnaire on three occasions during the season. The results from a doubly multivariate repeated-measures MANOVA revealed a significant Player Status x Time of Assessment interaction. Follow-up analyses for player status differences indicated that perceived ability contributed substantially to group differences. Specifically, starters rated their perceived ability higher than survivors at all three assessments, and higher than nonstarters at the initial assessment. For the time-of-season differences, only survivors differed significantly across the three assessments on the mastery and ability goal orientations, and level of satisfaction. Results indicated that the end-of-season assessments for survivors were lower on each measure than at both the tryout and prior-to-competition assessments.
