Objectives

This study examined the construct validity of a measure of psychopathy derived from Add Health data.

Methods

Two recruitment sites were used, resulting in 446 undergraduate participants in sample 1, and 332 undergraduate participants in sample 2. In addition to the measure from the Add Health data, participants completed three well-validated self-report measures of psychopathy, a measure of general personality, and measures of externalizing behaviors (e.g., crime and aggression).

Results

Factor analyses failed to confirm a one-factor solution consistent with the original Add Health measure; instead, a five-factor solution fit the data best. The Add Health measure failed to demonstrate convergent and criterion validity. Alternate coding and subscales showed some improvement; however, content and construct validity remained lacking.

Conclusions

The Add Health measure is not a valid measure of psychopathy and its continued use is not recommended.

Add Health心理疾病量表：评估其结构效度

目标

这项研究检查了从Add Health数据得出的一种精神病量度的结构效度。

方法

使用了两个招聘站点，样本1中的446名本科生和样本2中的332名本科生。除了Add Health数据中的测度外，参与者还完成了三项经过充分验证的自我报告的精神病自我测度，即一般人格，以及衡量行为外在化的手段（例如犯罪和侵略）。

结果

因子分析未能确认与原始“添加健康”指标一致的单因子解决方案；相反，五因素解决方案最适合数据。“添加健康状况”度量未能证明收敛性和标准有效性。替代编码和分量表显示了一些改进；但是，内容和结构的有效性仍然缺乏。

结论

“添加健康”措施不是对精神疾病的有效措施，不建议继续使用。
