Personal and social aspects of professional identity.: An extension of Marcia's identity status model applied to a sample of university students

The study proposed an extension of Marcia's identity status model based on validation of the Professional Identity Status Questionnaire (PISQ-5d), a scale able to measure both intra-individual and intergroup processes connected with the development of a professional identity in university students. The aims were to prove the construct validity of the PISQ-5d, to determine the appropriate number of identity statuses, and to assess the concurrent validity of the identity statuses considering both job-related and academic factors. In this study, 477 university students completed a questionnaire with the PISQ-5d scale; 220 also completed the measures of work values; and 168 completed the measures of student self-esteem and self-efficacy, academic motivation, and grades. Results confirmed the expected five-dimensional structure of the PISQ-5d and the scale's effectiveness at differentiating five types of identity status. Relationship between professional identity status and job-related and academic factors showed that the students with achievement or foreclosure identities had higher scores on measures of academic self-esteem and intrinsic work value and had lower scores for intention to leave university. Implications in terms of considering the PISQ-5d scale a useful tool for the evaluation of professional identity construction processes in university students will be discussed.
