The concordance between self‐ and observer‐ratings was investigated for items on Kasahara's Inventory for the Melancholic Type Personality (KIMTP). Subjects consisted of 44 patients diagnosed with an ICD‐10 diagnostic criteria for research (DCR) depressive episode (F32) or recurrent depressive disorder (F33) unipolar affective disorder, and 44 observers. Thirty‐one of the 44 patients were diagnosed with endogenous depression. The observers consisted of five parents, eight children, thre siblings, 25 spouses, and three partners. Concordance was tested with Student's paired t ‐test and one‐way analysis of variance intraclass correlation coefficient ( ANOVA ICC). There was no statistical difference between the mean total self‐rating score and the mean total observer‐rating score in the endogenous depression group, but the mean total self‐rating score was significantly higher than the mean total observer‐rating score in the non‐endogenous depression group. When the self and observer tests in this non‐endogenous depression group were compared on an item‐by‐item basis, most items tended to receive higher scores from the self‐raters than from the observer‐raters. The ICC had good concordance for mean total self‐ and observer‐ratings in the endogenous depression group but not the non‐endogenous depression group. On an item‐by‐item basis, concordance was high between self‐ and observer‐raters for more items in the endogenous depression group than in the non‐endogenous depression group. There were some important differences between self‐ and observer‐ratings for certain items in the non‐endogenous depression group. Patients in this group tended to give higher scores to items representing Typus melancholicus in relation to scores given by observers.
