Vocational identity is one core component of identity construction in adolescence.
The current study investigated whether vocational interest structure in terms of
differentiation, coherence, elevation, and interest–aspiration congruence would
differentiate among students in vocational identity achievement, foreclosure,
moratorium, and diffusion. Swiss students at the beginning of eighth grade (N ¼ 341) participated in the study. Groups were created using cluster analysis based on the dimensions of career exploration and career commitment, and group differences were explored with discriminant analysis. Controlling for sociodemographic variables, higher interest differentiation and elevation distinguished students in achievement/moratorium from those in diffusion. More interest elevation differentiated moratorium from foreclosure.
