Relationship of level of functioning to self-reported and rated psychopathology.

Performed a principal components analysis on the intercorrelations among the nine same-named scales of the Symptom Check List-90R (SCL-90R) and the Symptom Check List-90 Analogue (Analogue) for 118 female and 62 male outpatients admitted to a community mental health center. The SCL-90R scales constituted one component that reflected self-reported psychopathology, whereas the Analogue scales revealed two components that represented rated psychotic and nonpsychotic aspects of psychopathology. When the three latter components, age, race, sex, marital status, educational attainment, and employment status were correlated with Philadelphia's Adult Level of Functioning Scale (LOF scale), only the two clinically rated components and educational attainment were related significantly to level of functioning. The findings were discussed as supporting use of both self-report and clinical measures for evaluating psychopathology.
