Open Access Senior Honors Thesis
The Depressive Personality Disorder Inventory (DPDI) was created by Dr. Steven Huprich to assess depressive personality in clinical and nonclinical samples. A statistical method called varimax factor analysis was used to compare DPDI scores of 851 individuals with scores on the Beck Depression Inventory-II (BDI-II). Resulting data showed the two measures were highly intercorrelated. Subsequent revisions were made to the DPDI to increase its utility as an assessment tool while also maintaining internal consistency.
