Whose Outcomes Come Out? Patterns of Caregiver- and Youth-reported Outcomes Based on Caregiver-youth Baseline Discrepancies.

OBJECTIVE: Discrepancies between caregiver and youth reports of emotional and behavioral symptoms are well-documented, with cross-informant correlations often falling in the low to moderate range. Studies have shown that caregiver-youth (dis)agreement in reporting of youth symptoms is related to treatment outcomes. However, commonly used methods for exploring reporter discrepancies (e.g., difference scores) are limited by their inability to assess discrepancies across multiple symptom domains simultaneously, and thus these previous findings do not explore multiple patterns of (dis)agreement. METHOD: We used latent profile analysis (LPA) to identify subgroups of clinically referred youths based on patterns of caregiver- and youth-reported internalizing and externalizing symptoms for 174 caregiver-youth dyads. Longitudinal multilevel models were used to examine changes in weekly caregiver- and youth-reported internalizing symptoms, externalizing symptoms, and top problems for identified subgroups. RESULTS: The LPA identified four latent subgroups: (a) Caregiver Internalizing (9%), (b) Caregiver Internalizing-Externalizing (45%), (c) Youth Internalizing (7%), and (d) Caregiver-Youth Internalizing-Externalizing (39%). Clinical outcomes varied across informants and subgroups. Significant improvements in caregiver- and youth-reported outcome measures were documented within the Caregiver Internalizing, Caregiver Internalizing-Externalizing, and Caregiver-Youth Internalizing-Externalizing subgroups. However, only youth-reported improvements were detected in the Youth Internalizing subgroup. The results show differences in treatment outcomes across caregiver-youth informant subgroups. CONCLUSIONS: These findings suggest how youth and caregiver baseline data could provide guidance for clinicians in interpreting discrepant reporting and its relevance to change during treatment.
