南亚缺乏关于 PHQ-9 和 GAD-7 的阶乘结构和不变性的跨文化证据。关于使用这些量表的单位加权分数（项目分数的总和）的建议没有充分的依据。本研究旨在利用印度农村人口的数据来解决这些背景和方法上的差距。该研究调查了喀拉拉邦糖尿病预防计划的 1,209 名 30-60 岁参与者（有糖尿病风险的人数 = 1,007 人，患有糖尿病的人数 = 202 人）。使用 PHQ-9 和 GAD-7 在 2 年内对 1,007 名参与者进行了调查。使用双因子-(S – 1) 建模和多组验证性因子分析。因子分析支持这两个量表都存在躯体和认知/情感子成分，但对于 GAD-7 则不太明确。 PHQ-9 的分层 omega 值为 0.72，GAD-7 的分层 omega 值为 0.76。两种量表均显示出完全标量不变性以及随年龄、性别、教育程度、糖尿病状况和时间的完全或部分残差不变性。通过单位加权分数与潜在均值衡量的类别之间的效应大小遵循类似的趋势，但潜在均值系统性较高。对于这两种疾病，女性和较低的教育程度与较高的症状严重程度评分相关，这与区域和全球趋势相对应。对于这两个量表，心理测量特性与西方环境中的研究相当。不同的临床特征（躯体认知）支持抑郁症，并且在较小程度上支持焦虑症。应谨慎使用全量表的单位加权分数，而不建议对子量表评分。这些量表的稳定性支持它们的使用，并允许在测试的亚组之间进行有意义的比较。澳大利亚和新西兰临床试验注册中心：ACTRN12611000262909 http://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=336603&isReview=true。
Cross-cultural evidence on the factorial structure and invariance of the PHQ-9 and the GAD-7 is lacking for South Asia. Recommendations on the use of unit-weighted scores of these scales (the sum of items’ scores) are not well-founded. This study aims to address these contextual and methodological gaps using data from a rural Indian population. The study surveyed 1,209 participants of the Kerala Diabetes Prevention Program aged 30–60 years (n at risk of diabetes = 1,007 and n with diabetes = 202). 1,007 participants were surveyed over 2 years using the PHQ-9 and the GAD-7. Bifactor-(S – 1) modeling and multigroup confirmatory factor analysis were used. Factor analysis supported the existence of a somatic and cognitive/affective subcomponent for both scales, but less explicitly for the GAD-7. Hierarchical omega values were 0.72 for the PHQ-9 and 0.76 for the GAD-7. Both scales showed full scalar invariance and full or partial residual invariance across age, gender, education, status of diabetes and over time. Effect sizes between categories measured by unit-weighted scores versus latent means followed a similar trend but were systematically higher for the latent means. For both disorders, female gender and lower education were associated with higher symptom severity scores, which corresponds with regional and global trends. For both scales, psychometric properties were comparable to studies in western settings. Distinct clinical profiles (somatic-cognitive) were supported for depression, and to a lesser extent for anxiety. Unit-weighted scores of the full scales should be used with caution, while scoring subscales is not recommended. The stability of these scales supports their use and allows for meaningful comparison across tested subgroups.
