The 21-item English version of the Depression Anxiety Stress Scale (DASS-21) has been proposed as a method for assessing self-perceived depression, anxiety and stress over the past week in various clinical and nonclinical populations. Several Malay versions of the DASS-21 have been validated in various populations with varying success. One particular Malay version has been validated in various occupational groups (such as nurses and automotive workers) but not among male clinic outpatient attendees in Malaysia.
To validate the Malay version of the DASS-21 (Malay-DASS-21) among male outpatient clinic attendees in Johor.
A validation study with a random sample of 402 male respondents attending the outpatient clinic of a major public outpatient clinic in Johor Bahru and Segamat was carried out from January to March 2016. Construct validity of the Malay-DASS-21 was examined using Exploratory Factor Analysis (KMO = 0.947; Bartlett's test of sphericity is significant, p<0.001) through Principal Component Analysis and orthogonal (varimax) rotation with Kaiser Normalization to confirm the psychometric properties of the Malay-DASS- 21 and the internal consistency reliability using Cronbach's alpha.
Construct validity of the Malay-DASS-21 based on eigenvalues and factor loadings to confirm the three factor structure (depression, anxiety, and stress) was acceptable. The internal consistency reliability of the factor construct was very impressive with Cronbach's alpha values in the range of 0.837 to 0.863.
The present study showed that the Malay- DASS-21 has acceptable psychometric construct and high internal consistency reliability to measure self-perceived depression, anxiety and stress over the past week in male outpatient clinic attendees in Johor. Further studies are necessary to revalidate the Malay-DASS-21 across different populations and cultures, and using confirmatory factor analyses.
21项英文版抑郁焦虑压力量表（DASS - 21）已被提议作为一种评估过去一周内不同临床和非临床人群自我感知的抑郁、焦虑和压力的方法。DASS - 21的几个马来语版本已在不同人群中得到验证，但成效各异。其中一个特定的马来语版本已在不同职业群体（如护士和汽车工人）中得到验证，但尚未在马来西亚男性门诊患者中得到验证。
在柔佛州的男性门诊患者中验证马来语版的DASS - 21（马来语 - DASS - 21）。
2016年1月至3月，对柔佛州新山和昔加末一家大型公立门诊的门诊患者中402名男性受访者的随机样本进行了一项验证研究。通过主成分分析和正交（方差最大化）旋转，并采用Kaiser标准化，使用探索性因子分析（KMO = 0.947；Bartlett球形检验显著，p<0.001）来检验马来语 - DASS - 21的结构效度，以确认马来语 - DASS - 21的心理测量特性，并使用Cronbach's alpha检验内部一致性信度。
基于特征值和因子载荷来确认三因素结构（抑郁、焦虑和压力）的马来语 - DASS - 21的结构效度是可以接受的。因子结构的内部一致性信度非常可观，Cronbach's alpha值在0.837至0.863之间。
本研究表明，马来语 - DASS - 21具有可接受的心理测量结构和较高的内部一致性信度，可用于测量柔佛州男性门诊患者过去一周内自我感知的抑郁、焦虑和压力。有必要进行进一步研究，以在不同人群和文化中重新验证马来语 - DASS - 21，并使用验证性因子分析。
