title: Psychometric properties of the Spanish version of the diagnostic interview for depressive personality.
abstract: The aim of this study was to evaluate the reliability and validity of the Spanish-language version of the diagnostic interview for depressive personality (DIDP). The DIDP was administered to 328 consecutive outpatients and the test-retest and inter-rater reliability were assessed. Factor analysis was used in search of factors capable of explaining the scale and a cutoff point was established. The DIDP scales showed adequate Cronbach's α values and acceptable test-retest and inter-rater reliability coefficients. Convergent and discriminant validity were explored, the latter with respect to avoidant and borderline personality disorders. The results of the factor analysis were consistent with the four-factor structure of the DIDP scales. The receiver operating characteristic (ROC) analysis revealed the area under the curve to be 0.848. We found 30 to be a good cutoff point, with a sensitivity of 74.5% and a specificity of 78.5%. The DIDP proved to be a reliable and valid instrument for assessing depressive personality disorder, at least among our outpatients. The psychometric properties of the DIDP support its clinical usefulness in assessing depressive personality.
