Depression and anxiety are recognised increasingly as serious public health problems among women in low- and lower-middle income countries. The aim of this study was to validate the 21-item Depression Anxiety and Stress Scale (DASS21) for use in screening for these common mental disorders among rural women with young children in the North of Vietnam.
The DASS-21 was translated from English to Vietnamese, culturally verified, back-translated and administered to women who also completed, separately, a psychiatrist-administered Structured Clinical Interview for DSM IV Axis 1 diagnoses of depressive and anxiety disorders. The sample was a community-based representative cohort of adult women with young children living in Ha Nam Province in northern Viet Nam. Cronbach's alpha, Exploratory Factor Analyses (EFA) and Receiver Operating Characteristic (ROC) analyses were performed to identify the psychometric properties of the Depression, Anxiety, and Stress subscales and the overall scale.
Complete data were available for 221 women. The internal consistency (Cronbach's alpha) of each sub-scale and the overall scale were high, ranging from 0.70 for the Stress subscale to 0.88 for the overall scale, but EFA indicated that the 21 items all loaded on one factor. Scores on each of the three sub-scales, and the combinations of two or three of them were able to detect the common mental disorders of depression and anxiety in women with a sensitivity of 79.1% and a specificity of 77.0% at the optimal cut off of >33. However, they did not distinguish between those experiencing only depression or only anxiety.
The total score of the 21 items of the DASS21-Vietnamese validation appears to be comprehensible and sensitive to detecting common mental disorders in women with young children in primary health care in rural northern Vietnam and therefore might also be useful to screen for these conditions in other resource-constrained settings.
在中低收入国家，抑郁和焦虑已被公认为女性面临的严重公共卫生问题。本研究旨在验证 21 项抑郁焦虑和压力量表（DASS21）在越南北部农村地区有年幼子女的女性中筛查这些常见精神障碍的适用性。
将 DASS-21 从英文翻译为越南文，进行文化验证，回译，并对单独完成 DSM-IV 轴 1 诊断的精神科医生进行的抑郁和焦虑障碍结构性临床访谈的妇女进行管理。该样本是一个基于社区的成年女性代表性队列，她们的孩子年幼，居住在越南北部的河静省。进行了克朗巴赫的 α、探索性因素分析（EFA）和接收者操作特征（ROC）分析，以确定抑郁、焦虑和压力分量表以及总量表的心理计量特性。
共有 221 名妇女提供了完整数据。每个分量表和总量表的内部一致性（克朗巴赫的α）都很高，范围从压力分量表的 0.70 到总量表的 0.88，但 EFA 表明 21 个项目都加载在一个因子上。三个分量表中的每个分量表的分数，以及其中两个或三个的组合，都能够以 33 分以上的最佳切点检测出女性的常见精神障碍，其敏感性为 79.1%，特异性为 77.0%。然而，它们无法区分仅患有抑郁症或仅患有焦虑症的患者。
DASS21-越南验证的 21 项总分似乎易于理解，并且能够敏感地检测出越南北部农村初级保健中年轻子女的女性常见精神障碍，因此在其他资源有限的环境中也可能有用以筛查这些疾病。
