This study aimed to examine the psychometric properties of the PROMIS depression, anxiety, and anger item banks in a large Australian population-based sample. The study tested for unidimensionality; evaluated invariance across age, gender, and education; assessed local independence; and tested item bank scores as an indicator for clinical criteria. In addition, equivalence of the 7-day time frame against an alternative 30-day time frame was assessed. A sample of 3,175 Australian adults were recruited into the study through online advertising. All three item banks showed strong evidence of unidimensionality and parsimony, with no items showing local dependence. All items were invariant across age, gender, and education. The item banks were accurate in detecting clinical criteria for major depressive disorder, generalized anxiety disorder, and panic disorder, although legacy measures designed for this purpose sometimes performed marginally better. Responses to the 30-day time frame were highly consistent with the original 7-day time frame. The study provided support for the validity of the PROMIS emotional distress item banks as measures of depression, anxiety, and anger in the Australian population, supporting the generalizability of the measures. The time frame chosen for assessing mental health outcomes using these item banks should be based on pragmatic considerations.
本研究旨在检验 PROMIS 抑郁、焦虑和愤怒项目库在澳大利亚大样本人群中的心理测量特性。该研究检验了单维性；评估了年龄、性别和教育方面的不变性；评估了局部独立性；并测试了项目库分数作为临床标准的指标。此外，还评估了 7 天时间框架与替代的 30 天时间框架的等效性。通过在线广告，从 3175 名澳大利亚成年人中招募了一个样本参与研究。所有三个项目库都显示出很强的单维性和简约性，没有任何项目显示出局部依赖性。所有项目在年龄、性别和教育方面都是不变的。项目库在检测重性抑郁障碍、广泛性焦虑障碍和惊恐障碍的临床标准方面具有较高的准确性，尽管为此目的设计的传统测量方法有时表现略好。对 30 天时间框架的反应与原始的 7 天时间框架高度一致。该研究为 PROMIS 情绪困扰项目库作为澳大利亚人群中抑郁、焦虑和愤怒的测量工具的有效性提供了支持，支持了这些测量工具的可推广性。使用这些项目库评估心理健康结果时选择的时间框架应基于实际考虑。
