Depressive symptoms in psychotic disorders are of high relevance but seem to be heterogeneous when assessed with a standard rating scale. The present analysis is a replication study on the dimensionality of the Bech-Rafaelsen Melancholia Scale (BRMES) in acutely psychotic patients with substantial depression defined according to a functional approach across the nosological borders of schizophrenia with major affective symptoms, schizoaffective disorder, depressed subtype, and major depression with psychotic features. The baseline data of 123 patients participating in a multicenter pharmacological trial were evaluated with structural equation models. A previously reported three-dimensional model of the BRMES comprising the facets retardation, depressive core symptoms, and accessory depressive symptoms was cross-validated by confirmatory factor analysis (CFA). The three-dimensional model proved to be superior to one-, two-, or four-factor models with respect to goodness-of-fit (goodness-of-fit index [GFI] = 0.91 and comparative fit index [CFI] = 0.89) and parsimony (adjusted GFI [AGFI] = 0.85). When comparing the present model with the previously reported model, a highly satisfactory correspondence emerged (CFI = 0.87). The results corroborate our previous findings that depression-like symptoms in acutely psychotic patients assessed by the BRMES can best be represented by a three-dimensional model and should not be treated as a homogeneous syndrome.
