Peteroy, Pirrello, and Adams' (1982) findings on two Wiggins content scales, DEP and PSY, were re-examined. In contrast to Peteroy et al.'s results, both scales were found to relate significantly to length of psychiatric hospitalization (LOH) when a larger, more heterogeneous sampling (N = 362) was employed, together with a wider range of LOH values. This study demonstrates how attention to relevant sampling parameters in predictive validity studies can help to ensure that the utility of measures such as PSY is not misjudged.
对彼得罗伊、皮雷洛和亚当斯（1982年）关于威金斯两个内容量表（DEP和PSY）的研究结果进行了重新审视。与彼得罗伊等人的结果相反，当采用更大、更具异质性的样本（N = 362）以及更广泛的精神科住院时间（LOH）值时，发现这两个量表都与精神科住院时间显著相关。这项研究表明，在预测效度研究中关注相关抽样参数有助于确保不会错误判断诸如PSY等测量方法的效用。
