This study examines relationships between identity status and process measure scores that advance our understanding of methodological characteristics in the context of gender and age. A sample of 391 adolescents and adults (215 males, 176 females) completed the Identity Style Inventory (ISI; Berzonsky, 1992) and Ego Identity Process Questionnaire (EIPQ; Balisteri, Busch-Rossnagel, & Geisinger, 1995). Two of three identity processing styles were related significantly with age; moderated by gender and status. Exploration and commitment were significantly associated with informational and normative style, respectively. The two commitment measure scores were significantly related. Informational identity style and the exploration and commitment measures increased with age. Identity diffused orientation decreased over time and was more prevalent among males. Support was limited for the stability of identity style over time. These findings, founded on a broad age range, help test assumptions regarding the role of maturation and the identity style model in particular.
