本研究的目的是评估抑郁性人格障碍问卷(DPDI；Huprich，Margrett，Barthelemy，&Fine，1996)的心理测量学特性。DPDI被发现在本科生和老兵精神科门诊人群中都具有很强的内部一致性。DPDI与抑郁人格的其他测量有显著的正相关，支持其收敛效度。即使在控制了状态样抑郁之后，这些关系仍然存在，这表明DPDI具有递增的有效性。DPDI还显著预测人际关系损失的得分，即使在控制了状态样抑郁之后也是如此，表明DPDI具有良好的结构效度。为了支持区分效度，DPDI与抑郁人格的另一种衡量标准的相关性比与其他人格障碍的衡量标准更高。最后，DPDI有很强的诊断效率统计：(A)灵敏度=0.82，(B)特异度=0.80，(C)阳性预测力=0.75，(D)阴性预测力=0.86，以及(E)总体诊断能力=0.81。DPDI似乎具有良好的心理测量学特性。
The purpose of this study was to evaluate the psychometric properties of the Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996). The DPDI was found to have strong internal consistency in both an undergraduate and a veteran, psychiatric outpatient population. The DPDI had significant, positive correlations with other measures of depressive personality, supporting its convergent validity. These relationships remained even after controlling for state-like depression, suggesting that the DPDI has incremental validity. The DPDI also significantly predicted scores on measures of interpersonal loss, even after controlling for state-like depression, suggesting that the DPDI has good construct validity. In support of discriminant validity, the DPDI was more correlated with another measure of depressive personality than it was with measures of other personality disorders. Finally, the DPDI had strong diagnostic efficiency statistics: (a) Sensitivity =.82, (b) Specificity =.80, (c) Positive Predictive Power =.75, (d) Negative Predictive Power =.86, and (e) Overall Diagnostic Power =.81. It appears that the DPDI has good psychometric properties.
