Within the psychometric framework of assessing a measure's dependability (Watson, 2004), this study considered the 2-week and 5-week test-retest correlations of the Depressive Personality Disorder Inventory (DPDI; Huprich, Margrett, Barthelemy, & Fine, 1996). DPDI scores were compared with the test-retest reliability (i.e., dependability) of the Beck Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996). Three-hundred sixty-three undergraduates completed the DPDI and BDI-II and were reevaluated at either a 2- or 5-week interval. Two- and 5-week test-retest correlations for the DPDI were .89 and .82, respectively, and test-retest correlations for the BDI-II were .88 and .75. The effect sizes of the mean scores' changes in the measures across time were larger for the DPDI (ds = .48, .23) than the BDI-II (ds = .28, -.21), with mean BDI-II scores not significantly differing at the 5-week assessment from the baseline mean. Although the 5-week retest correlation for the BDI-II trended toward decreasing reliability from baseline, it did not significantly differ from the DPDI 5-week retest correlation. It is concluded that both measures are dependable and assess latent propensities toward depressive thoughts and feelings, along with the current influence of depressive states.
在评估测量可靠性的心理计量学框架内（Watson，2004），本研究考虑了抑郁人格障碍量表（DPDI；Huprich、Margrett、Barthelemy 和 Fine，1996）的 2 周和 5 周测试重测相关性。DPDI 分数与贝克抑郁量表-II（BDI-II；Beck、Steer 和 Brown，1996）的测试重测可靠性（即可靠性）进行了比较。363 名本科生完成了 DPDI 和 BDI-II 测试，并在 2 周或 5 周的时间间隔内进行了重新评估。DPDI 的 2 周和 5 周测试重测相关性分别为.89 和.82，BDI-II 的测试重测相关性分别为.88 和.75。跨时间测量中平均分数变化的效应大小在 DPDI 上更大（ds =.48，.23），而在 BDI-II 上更小（ds =.28，-.21），5 周评估时的 BDI-II 平均分数与基线平均分数没有显著差异。虽然 BDI-II 的 5 周重测相关性趋于从基线开始降低可靠性，但与 DPDI 的 5 周重测相关性没有显著差异。结论是，这两种测量都可靠，评估潜在的抑郁思维和感觉倾向，以及当前的抑郁状态影响。
