Researchers often question the validity of multi-informant assessments among adolescents with child welfare involvement. Yet, within other clinical populations, prior research finds that multi-informant reports have a discernable structure characterized by discrete patterns of agreement and disagreement. This structure "tracks" contextual displays of behavior and clinical severity. We examined the structure of multi-informant reports (i.e., adolescent, caregiver, teacher) of adolescent externalizing and internalizing problems in a sample of adolescents with a history of child welfare involvement. Across problem domains and informants, reporting patterns mirrored those observed in other clinical populations, and displayed characteristics robustly present in meta-analytic work on cross-informant correspondence. Specifically, informants agreed more on reports of externalizing problems than internalizing problems and caregiver-teacher dyads agreed more than adolescent-caregiver dyads. Overall, we found robust, replicable patterns of multi-informant reports among child welfare involved adolescents. These reporting patterns may facilitate use and interpretation of multi-informant evidence-based assessments among this population.
