Structural, Relative, and Absolute Agreement between Parents' and Adolescent Inpatients' Reports of Adolescent Functional Impairment

This study assessed agreement between parents' and adolescent inpatients' scores on caretaker and self-report versions of the Functional Impairment Scale for Children and Adolescents (FISCA and FISCA-SR). Self-report data describing impairment in eight domains were collected from 375 inpatients (M age = 15.0 years, 55% females), with parent data available for 233 (62%). Confirmatory factor analysis demonstrated structural congruence between a hypothesized, three-factor model, based on a prior study of the parent FISCA, and an observed model, based on responses to the FISCA-SR (GFI = .95). Correlations (measuring relative agreement) and paired comparisons of means (assessing absolute agreement) generally identified stronger agreement in public than private domains of impairment, and greater relative than absolute agreement in covert, antisocial domains.
