Three studies examining the factor structure and psychometric properties of the Anxiety Depression Distress Inventory-27 (ADDI-27) extended the initial instrument development studies for this recently introduced inventory. The ADDI-27 is an empirically derived short form of the Mood and Anxiety Questionaire-90 (MASQ-90) comprising three scales: Positive Affect, Somatic Anxiety, and General Distress. The main objectives of Study 1 (N = 700) were to examine the factor structure of the ADDI-27 and its measurement invariance across gender at the item level. The objective of Study 2 (N = 538) was to examine evidence for the convergent and discriminant validity of scores on the ADDI-27. The objective of Study 3 (N = 240) was to assess further evidence for the nomological network and convergent and discriminant validity of the ADDI-27 scores. Results of exploratory structural equation modeling yielded strong support for a 3-factor model, with approximate fit indexes meeting or exceeding the conventional cutoffs. With p ≤ .001 as the criterion for detecting noninvariance, results of measurement invariance analysis suggested that all of the ADDI-27 items were invariant across gender. Results of multivariate validity analyses across 2 studies provided support for the convergent and discriminant validity of scores on the ADDI-27 scales.
三项研究检验了焦虑抑郁困扰量表-27（ADDI-27）的因子结构和心理测量特性，扩展了该新引入量表的初始工具开发研究。ADDI-27 是情绪和焦虑问卷-90（MASQ-90）的经验衍生的简短形式，包含三个量表：积极情绪、躯体焦虑和一般困扰。研究 1（N = 700）的主要目的是检验 ADDI-27 的因子结构及其在项目水平上的性别测量不变性。研究 2（N = 538）的目的是检验 ADDI-27 得分的收敛和区分效度的证据。研究 3（N = 240）的目的是进一步评估 ADDI-27 得分的效标网络和收敛及区分效度的证据。探索性结构方程建模的结果强烈支持 3 因素模型，近似拟合指数符合或超过传统的截止值。以 p ≤.001 作为检测非不变性的标准，测量不变性分析的结果表明，ADDI-27 的所有项目在性别上都是不变的。两项研究的多元有效性分析结果支持 ADDI-27 量表得分的收敛和区分效度。
