ENThe present investigation evaluated multiple patterns of change and stability in Berzonsky’s identity styles (informational, normative, and diffuse-avoidant) in a four-annual-wave longitudinal study with 468 adolescent boys and girls from Lithuania. A combination of mean level changes, high rank-order stability, and high profile stability has been found in this study. First, levels of informational and normative identity styles remained stable for girls, but decreased significantly for boys; levels of diffuse-avoidant identity styles remained stable for girls and boys. Second, the rank-order stability of the normative and diffuse-avoidant styles was lower for boys, than for girls. Third, the mean profile stability was high for girls and moderate for boys. In general, our findings highlighted substantial gender differences in multiple indices of change and stability of identity styles. [From the publication]
