The Identity Style Inventory: A Revision with a Sixth-Grade Reading Level (ISI-6G)

The Berzonsky (1992b) Identity Style Inventory (ISI) was revised to a sixth-grade reading levelfor use with adolescents and adults with reading limitations. This version of the ISI differs from the original version, which was developed with college students and had a higher than ninth-grade reading level. College students (N = 361) were given both versions of the ISI in a counterbalanced order The revised ISI (ISI-6G) scales (Information, Normative, and Diffuse/Avoidant) were found to be reliable and valid. Construct validity was demonstrated through factor analysis and paired sample t-tests. Correlations between factor scores for each version were high (.79 through .84). Criterion validity was supported by the relations between the ISI-6G scales and predicted alcohol consumption patterns, level of expressed optimism, codependence, and religiosity. Overall, the ISI-6G was comparable to the original ISI and could be used with adolescents and adults.
