title: Dimensions of the Typus melancholicus personality type.
abstract: The Typus melancholicus personality type (TMP) is characterised by orderliness, conscientiousness and interpersonal dependence. Several standardised instruments have been developed for the assessment of the Typus melancholicus personality. To date there has been no systematic comparison of these instruments and in particular it has been unclear whether TMP represents a single trait or a personality trait constellation. The aim of this study was the comparison of four TMP questionnaires and the investigation of the dimensionality of the personality as revealed by these questionnaires. The factorial validity of four TMP questionnaires was examined based on a sample of n = 264 psychiatric inpatients and normal controls. In a factor analysis of the items of the TMP questionnaires, four dimensions could be differentiated: Dependence, Intolerance of Ambiguity, Norm-Orientation, and Perfectionism. Psychometric evaluation showed good values for the individual items and the new TMP scales. The four subscales had a differential correlation profile in relation to the dimensions of the five-factor model of personality. The TMP scales could distinguish a group of depressed patients from a group of normal controls. The results show that TMP personality is not a single trait but consists of four related but separate traits. These can be clearly distinguished from those of the five-factor model of personality. The analysis of the TM concept therefore also represents a theoretical perspective for the integration of the personality characteristics which are relevant for depression. Based on this analysis, we constructed a multidimensional TMP inventory which forms the basis for the investigation of the effect of TM personality on clinical outcome and on psychotherapeutic treatment.
