Based on the theory of reasoned action (TRA; Fishbein & Ajzen, 1975), we hypothesized that young women's career intentions would be predicted by their gender-role attitudes and perceptions of their boyfriends' and parents' career-related preferences for them. Career intention was expected to predict future career behavior. The model was tested using longitudinal data from 105 women studied in 1973 and followed up 14 years later in 1987. Data were analyzed using structural equation modeling. Results supported the TRA: women's gender-role attitudes and their perceptions of important others' preferences predicted their career intentions, which predicted career behavior 14 years later. Implications for the study of women's careers and the longitudinal application of the TRA are discussed.
