Identity styles represent strategies individuals use to explore identity-related issues. Berzonsky (Berzonsky, M. D. (1992). Identity style and coping strategies. "Journal of Personality, 60", 771-788) identified three styles: informational, normative, and diffuse. In three studies, this paper presents (a) the identity processing style Q-sort (IPSQ), a new measurement technique for assessing identity styles, along with the reliability and validity of three criterion sorts that represent "ideal types" for the three respective styles, (b) a description of the styles in a sample of 480 college students along with direct comparisons with the paper-pencil measure of identity styles originally developed by Berzonsky, and (c) an examination of convergent and discriminant validity of the IPSQ in a sample of 321 college students based on correlations with measures tapping identity status, family relationship quality, social competence, coping styles, and social desirability. The general discussion concludes that the reliability and validity of the sort are supported and future directions and potential uses are described. (Contains 6 tables.)
