Model fit indices of DERS-18 without “Awareness”.

ObjectiveThe Difficulties in Emotion Regulation Scale-18 (DERS-18) is an instrument used to measure deficits in emotion regulation. However, the instrument has not been adapted to Malaysians and has never been validated in the Malay language. This study aimed to examine the psychometric properties of the Malay version of DERS-18.MethodThe DERS-18 underwent forward-backward translation and assessment of face and content validity. Both Malay version of the DERS-18 and DASS-21 were completed by 701 adolescents (44.4% boys) aged 13 and 14 years old. To assess its dependability, a floor and ceiling effect evaluation and Cronbach’s analysis were both performed. A series of confirmatory factor analyses (CFA), bivariate correlation, and regression were performed to evaluate the construct and criterion validity, respectively.ResultsThe Malay version of DERS-18, after excluding “Awareness”, indicated excellent reliability (Cronbach’s α = 0.93), and acceptable internal consistency for each subscale (range of α from 0.63 to 0.82). Floor or ceiling effects were observed at item level and subscale level, but not at total level. CFA results revealed that the Malay version of the DERS-18 bifactor model (excluding “Awareness”) portrayed the best construct validity (χ2/df = 2.673, RMSEA = 0.049, CFI = 0.977, TLI = 0.968) compared to a single factor, a correlated factor, and a higher-order factor model. The DERS-18 subscales (except “Awareness”) and DERS-18 total scores were significantly correlated with stress, anxiety, and depression in a positive direction (r ranged from 0.62 to 0.64, p R2 ranged from 0.44 to 0.46, p ConclusionThe Malay version of the DERS-18, excluding “Awareness”, possessed good reliability, construct validity, and criterion validity to assess emotion dysregulation among Malaysian adolescents.### 研究目的 情绪调节困难量表-18（Difficulties in Emotion Regulation Scale-18, DERS-18）是用于评估情绪调节缺陷的标准化测评工具，但该量表尚未针对马来西亚人群进行文化适配，且从未开展过马来语版本的效度验证工作。本研究旨在检验马来语版DERS-18的心理测量学特性。 ### 研究方法 首先对DERS-18进行双向翻译，并开展表面效度与内容效度评估。共招募701名13至14岁的青少年（其中男生占比44.4%）完成马来语版DERS-18与抑郁焦虑压力量表-21（DASS-21）。为评估量表的可靠性，分别进行了地板效应、天花板效应检验以及克朗巴赫α系数（Cronbach’s α）分析。同时通过一系列验证性因子分析（Confirmatory Factor Analysis, CFA）、双变量相关分析与回归分析，分别检验其结构效度与效标效度。 ### 研究结果 剔除「情绪觉察（Awareness）」维度后，马来语版DERS-18展现出优异的内部一致性信度（克朗巴赫α=0.93），各子量表的内部一致性亦处于可接受范围（α值区间为0.63~0.82）。在条目与子量表层面存在地板或天花板效应，但总量表层面未出现此类现象。验证性因子分析结果显示，剔除「情绪觉察」维度后的双因子模型，相较于单因子、相关因子与高阶因子模型，展现出最优的结构效度（χ²/df=2.673，RMSEA=0.049，CFI=0.977，TLI=0.968）。马来语版DERS-18各子量表（「情绪觉察」除外）与总量表得分，均与压力、焦虑及抑郁水平呈显著正相关（相关系数r区间为0.62~0.64，p<0.001；决定系数R²区间为0.44~0.46，p<0.001）。 ### 研究结论 剔除「情绪觉察」维度后的马来语版DERS-18，具备良好的信度、结构效度与效标效度，可用于评估马来西亚青少年的情绪调节失调状况。
