Occupational identity development, school performance, and social support in adolescence: findings of a Dutch study.

Three hundred adolescents completed a Dutch version of the Dellas Identity Status Inventory-Occupation (DISI-O). Reliability of the five subscales ranged from "sufficient" to "very good," and the four identity status classifications accommodated about 90% of the respondents. As expected, achievement and social support by friends in the educational setting stimulated development of occupational identity.
