The Depressive Personality Disorder Inventory and its relationship to quality of life, hopefulness, and optimism.
The construct validity of the Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996) was examined through its relationship to the constructs of hope, optimism, and quality of life (QOL). Three hundred thirty-two undergraduate students were administered the DPDI and measures of the aforementioned constructs. As predicted, the DPDI negatively correlated with all measures. Individuals classified with a depressive personality disorder had significantly higher scores on measures of hope, optimism, and QOL compared to a control group. Stepwise regression analysis indicated that optimism, QOL, and one component of hope significantly predicted DPDI scores, although more variance was accounted for in women than men. These findings are explained in light of Carver and Scheier's (2000) explanation of optimism and its relationship to hope. In sum, it appears that the construct validity of the DPDI is supported within an undergraduate sample.
