BACKGROUND/PURPOSE: Dream emotions and contents are associated with psychological well-being. Dream disturbances, such as frequent nightmares and dream anxiety, are associated with a variety of psychopathological conditions. Therefore, it is important to consider nightmares and the resulting dream anxiety. To address this issue, the Van Dream Anxiety Scale (VDAS) was designed especially for measuring nightmare frequency and dream anxiety caused by frightening dreams. As a Chinese version of VDAS may be helpful in promoting study of nightmare and dream anxiety among Chinese population, in the current study, we sought to develop a Chinese version of the VDAS (CVDAS).
We translated the VDAS into Chinese. To evaluate its validity and reliability, a sample of 1,081 Chinese college students from two universities answered the CVDAS, GAD-7, PHQ-9 and EPQ-R-N. Ninety of them answered the CVDAS twice. We also conducted exploratory factor analysis (EFA) to explore the structure of CVDAS.
Excellent internal consistency (Cronbach's alpha coefficient was 0.926), split-half reliability (equal-length Spearman-Brown coefficient was 0.938) and good test-retest reliability (the intraclass correlation coefficient was 0.942 and t=-1.478, =0.143) of the CVDAS was presented. Exploratory factor analyses indicated a two-factor structure: sleep-related disturbances caused by nightmares and dysfunction caused by nightmares. Convergent and divergent validities were acceptable.
The CVDAS shows promise for the measurement of nightmare frequency and specific dream anxiety in Chinese population. Future study should confirm the reliability and validity in the clinical population and further improve this scale.
背景/目的：梦境情绪和内容与心理健康相关。梦境障碍，如频繁的噩梦和梦焦虑，与多种精神病理状况相关。因此，考虑噩梦及由此产生的梦焦虑很重要。为解决这一问题，范氏梦焦虑量表（VDAS）专门设计用于测量噩梦频率以及由可怕梦境引起的梦焦虑。由于VDAS的中文版可能有助于促进对中国人群中噩梦和梦焦虑的研究，在本研究中，我们试图开发VDAS的中文版（CVDAS）。
我们将VDAS翻译成中文。为评估其有效性和可靠性，来自两所大学的1081名中国大学生样本回答了CVDAS、广泛性焦虑障碍量表（GAD - 7）、患者健康问卷（PHQ - 9）和艾森克人格问卷简式量表（EPQ - R - N）。其中90人回答了两次CVDAS。我们还进行了探索性因素分析（EFA）以探究CVDAS的结构。
CVDAS呈现出出色的内部一致性（克朗巴哈α系数为0.926）、分半信度（等长斯皮尔曼 - 布朗系数为0.938）以及良好的重测信度（组内相关系数为0.942且t = -1.478，P = 0.143）。探索性因素分析表明其具有双因素结构：由噩梦引起的与睡眠相关的障碍以及由噩梦引起的功能障碍。聚合效度和区分效度均可接受。
CVDAS在测量中国人群的噩梦频率和特定梦焦虑方面显示出前景。未来研究应在临床人群中确认其信度和效度，并进一步完善该量表。
