This paper presents a replication of a study by Kiloh and Garside (1963). These workers carried out a factor analysis of 35 clinical features of 143 depressed patients. They demonstrated the presence of a factor which showed strong positive loadings with the clinical features classically accepted as characterizing neurotic depression and strong negative loadings with the clinical features characterizing endogenous depression. Of the 143 patients, 92 were diagnosed as more definitely suffering from endogenous or neurotic depression. Correlation coefficients were calculated between the diagnosis in these 92 cases and each clinical feature.
