Numerous studies have focused on characterizing personality differences between individuals with and without psychopathology. For drawing valid conclusions for these comparisons, the personality instruments used must demonstrate psychometric equivalence. However, we are unaware of any studies that examine measurement invariance in personality across individuals with and without psychopathology. This study conducted tests of measurement invariance for positive emotionality, negative emotionality, and disinhibition across individuals with and without histories of depressive, anxiety, and substance use disorders. We found consistent evidence that positive emotionality, negative emotionality, and disinhibition were assessed equivalently across all comparisons with each demonstrating strict invariance. Overall, results suggest that comparisons of personality measures between diagnostic groups satisfy the assumption of measurement invariance and these scales represent the same psychological constructs. Thus, mean-level comparisons across these groups are valid tests.
许多研究都集中在刻画有和没有精神病理学个体之间的人格差异。为了对这些比较得出有效的结论，所使用的人格工具必须表现出心理测量学等效。然而，我们不知道有任何研究检验人格在有和没有精神病理学个体之间的跨个体测量不变性。本研究对有和没有抑郁、焦虑和物质使用障碍病史的个体进行了正情绪、负情绪和去抑制的跨个体测量不变性检验。我们发现一致的证据表明，正情绪、负情绪和去抑制在所有比较中都是等同评估的，每个比较都表现出严格的不变性。总的来说，结果表明，在诊断组之间进行人格测量比较符合测量不变性的假设，这些量表代表了相同的心理结构。因此，这些组之间的平均水平比较是有效的检验。
