Vocational identity develops through the interplay between process and content dimensions. A three-wave longitudinal study investigated how identity process dimensions (in-breadth exploration, in-depth exploration, commitment making, identification with commitment, self-doubt, flexibility) and content dimensions represented by career goals (intrinsic goals, extrinsic goals) are interconnected across time. Participants were 327 full-time college students in South Korea at Time 1, 253 at Time 2, and 227 at Time 3. They rated values associated with their current career goal and completed the Vocational Identity Status Assessment 3 times with a 6-month interval. The autoregressive cross-lagged path analysis found positive reciprocal associations between intrinsic career goals and identification with commitment. Furthermore, intrinsic career goals positively predicted in-depth exploration, and self-doubt negatively predicted intrinsic career goals. These findings support the reciprocal relationships between vocational identity process and career goals in general, and between intrinsic career goals and the commitment dimension of identity more specifically.
