This study examined the mediation effect of career decision self‐efficacy in relation to work values and career decision status. The authors surveyed 308 college students about their own intrinsic (e.g., helping others) and extrinsic (e.g., high income) work values and those of significant others, career decision self‐efficacy, and career decision status. The results indicated that the intrinsic and extrinsic work values of significant others were related to the intrinsic and extrinsic work values of the self and that intrinsic work values were more adaptive than extrinsic work values in career development.
