The purpose of this investigation was to evaluate the effectiveness of a life development intervention on career transition adjustment in retired professional athletes. Intervention (n = 32) and control groups (n = 39) were recruited for this study, both of which contained recently retired male professional soccer players. Data were collected on measures of career termination adjustment and coping with transitions, and the intervention group also participated in a life development intervention package. Results revealed significant post-intervention treatment group differences on career transition adjustment in favor of the life development intervention, while significant within-group differences on career transition adjustment over time were also achieved for the intervention group. Results are discussed in relation to the personal and developmental costs of pursuing performance excellence.
