意象对话心理咨询技术中焦虑意象特征因子结构的分析

Analyses of anxiety imagery characteristic factor structure in imagery dialogue psychological counse-ling techniques

目的探索焦虑意象特征问卷的因子结构及有效性，作为对焦虑情绪判定和测量的依据。方法参照国内文献自行拟定焦虑意象特征因子49项调查问卷，对本院心理科来访者、武警某总队官兵和中南大学学生共221例进行调查，将49个条目的初测问卷测试106例，经过项目分析，确定了20个焦虑意象特征的正式施测问卷，测试115例，对数据进行主成分分析及因子选取，而后进行方差最大正交旋转法进行因子旋转，选定特征值〉1的主成分数目为因子数目，并进行KMO和Bartlett球形度检验分析。结果通过探索性因素分析，在10个项目中抽取特征值〉1的因子4个：情绪恐慌、心情不安、肌肉紧张、运动不安，4个因子共解释总方差的56．43％。验证性因子分析显示：卡方值与自由度之比（X^2／df）为2．151、近似误差均方根（RMSEA）为0．056、比较拟合指数（CFI）为0．923、拟合优度指数（GFI）为0．946、不规范拟合指数（NNFI）为0．874。结论10个特征的焦虑意象问卷构建了四因子结构，数据对模型拟合较好，验证焦虑意象特征四因子模型是合理的。可以作为焦虑情绪判定和测量的依据。

Objective To explore the factor structure of the anxiety imagery characteristics ques- tionnaire. Methods Through the literature review and expert group discussion, the initial anxiety imagery features questionnaire was created. The first questionnaire contained 49 items of anxiety imagery, which was answered by 106 imagery dialogue psychotherapists. After analysis of the items and exploratory faetors, the formal questionnaire that contained 20 items of anxiety imagery characteristics was formed. The formal ques- tionnaire was measured by 115 imagery dialogue psychotherapists, then, exploratory and confirmatory factor analyses were made. Results The exploratory factor analysis showed that four factors whose Eigen value were more than 1 were extracted from 10 items, including emotional panic, uneasy, tense muscles, and mo- tor restlessness. Those four factors explained 54. 39% of the total variance. Confirmatory analysis showed that X^2/df was 2. 142; root mean square error of approximation （RMSEA） was 0. 059; and comparative fit index （ CFI）, goodness-of-fit index （ GFI）, non-normed fit index （NNFI） and RSMEA was o. 912, 0. 935, 0. 896, and 0. 057, respectively. Conclusions The four-factor structure was constructed by 10 items of anxiety imagery characteristics questionnaire.
