[The exploration of the depressive personality disorder]

Abstract

Lately the concept of the depressive personality disorder has been regarded more often again in the context of chronic and subthreshold forms of depression. The purpose of the present study was the psychometric evaluation of a German version of the "Depressive Personality Disorder Inventory" (DPDI), which is a questionnaire for the exploration of the depressive personality disorder. A total of 138 depressive patients and controls were included in the study. The inter-rater-reliability as well as the internal consistency and the test-retest-reliability of the DPDI revealed satisfactory and good results. A short version of the DPDI was developed by means of a factor analysis. Medium correlations were found between the DPDI and two interviews for the depressive personality disorder. These results are discussed and it is concluded that the DPDI as well as its short version are reliable, valid and economic self-rating instruments for the exploration of the depressive personality disorder.
