Testing social cognitive interest and choice hypotheses across Holland types in Italian high school students

Several hypotheses emanating from social cognitive career theory (SCCT) were tested. Participants (796 Italian high school students) completed measures of self-efficacy, outcome expectations, interests, social supports and barriers, and choice consideration related to occupations representing Holland’s (1997) six RIASEC types. Findings indicated general support, across Holland types, for the hypotheses that self-efficacy and outcome expectations jointly predict interests, and that interests mediate the relations of self-efficacy and outcome expectations to choice consideration. However, the specific nature of the mediation effect (i.e., full versus partial) varied somewhat across the RIASEC types. In addition, contrary to SCCT’s predictions, social supports and barriers related to choice consideration mostly indirectly (through self-efficacy) rather than directly. We consider the implications of these findings for further research on SCCT’s choice and environmental hypotheses.
