Abstract

Cross-national study of adolescents' psychological adjustment requires measures that permit reliable and valid assessment across informants and nations, but such measures are virtually nonexistent. Item-response-theory-based linking is a promising yet underutilized methodological procedure that permits more accurate assessment across informants and nations. To demonstrate this procedure, the Resilience Scale of the Behavioral Assessment for Children of African Heritage (Lambert et al., 2005) was administered to 250 African American and 294 Jamaican nonreferred adolescents and their caregivers. Multiple items without significant differential item functioning emerged, allowing scale linking across informants and nations. Calibrating item parameters via item response theory linking can permit cross-informant cross-national assessment of youth.
