前驱症状量表是一种用于筛查个体患精神病风险的量表。它在临床和非临床人群（包括大学生）中具有很好的心理测量特性。然而，尚未在亚洲人、白色人、西班牙裔人和多种族样本中检查量表的测量不变性。美国两所大型公立大学共有2，767名本科生完成了前驱症状简介。总分具有几何和标量不变性，而痛苦评分显示几何、度量和部分标量不变性。后续分析显示，三个项目负责缺乏完整的标量不变性的痛苦分数。这表明，总评分和痛苦评分在各组中测量相同的结构，平均评分代表各组中相同水平的潜在前驱症状特征。不同种族之间的痛苦量表的平均值比较应谨慎解释，因为它缺乏完全的标量不变性。白色和西班牙裔参与者的总分低于多种族和亚洲参与者，这种模式出现在13个项目中。对于标量不变的痛苦项目，亚洲组比白色和西班牙裔组报告了更多的痛苦，而多种族组比白色组报告了更多的痛苦。
The Prodromal Questionnaire-Brief is a scale that is used to screen individuals for risk for the development of psychosis. It has promising psychometric properties in clinical and nonclinical populations, including undergraduates. However, the measurement invariance of the scale has not been examined in Asian, White, Hispanic, and Multiracial samples. A total of 2,767 undergraduates at two large public U.S. universities completed the Prodromal Questionnaire-Brief. The Total scores had configural and scalar invariance, while the Distress scores displayed configural, metric, and partial scalar invariance. Follow-up analyses revealed that three items were responsible for the lack of complete scalar invariance for the Distress scores. This suggests that the Total and Distress scores are measuring the same construct across groups and mean scores represent the same level of latent prodromal traits across groups. Mean comparisons for the Distress Scale across ethnicity should be interpreted with caution because it lacks complete scalar invariance. White and Hispanic participants had lower Total scores that Multiracial and Asian participants, and this pattern emerged for 13 items. For the distress items that were scalar invariant, the Asian group reported more distress than the White and Hispanic groups, while the Multiracial group reported more distress than the White group.
