        目的:(1)建立心境和焦虑症状问卷(MASQ)及相关影响因素量表的中文版,并分析其信度、效度;(2)应用建立的量表在湖南大学生人群中对焦虑的易感性-应激理论模式进行实证分析;(3)探索湖南大学生的焦虑易感性因素,初步构建大学生的易感性-应激整合模型。方法:(1)相关量表由加拿大McGill大学心理学系Abela教授提供给本研究使用。量表的中文版均经过了反复的翻译及回译。645名大学生完成了量表的初次测量,3-4周后选取其中的120-130人对相关的易感性因素量表进行了重测,6个月后对MASQ进行了追踪测试。信度检验采用Cronbach’sα系数、条目间平均相关系数和重测信度。效度检验包括内容效度和结构效度(总分与各因子分间的相关系数及验证性因素分析)。(2)用多层复回归分析进行焦虑症状的预测分析,并用路径分析和结构方程模型探索和整合了焦虑易感性-应激模型。结果:(1)MASQ全量表的Cronbach’sα系数为0.93,各分量表的Cronbach’sα系数在0.79-0.92之间:量表的条目间平均相关系数为0.17,各分量表的条目间平均相关系数在0.22-0.41之间;全量表的重测内部一致性系数(ICC)为0.70,各分量表的重测内部一致性系数在0.59-0.71之间,且都具有较显著的意义。(2)MASQ总分与其分量表得分有较强的相关(r>0.6),验证性因素分析显示MASQ四因子结构的拟合指数CFI、IFI、GFI都大于或等于0.9,RMSEA的值在0.1以下。(3)易感性因素各量表的信度、效度指标均达到测量学的要求。(4)多层复回归分析显示:神经质人格、负性认知×应激、不安全依恋×应激、神经质人格×应激、社会支持×应激都对焦虑有显著的预测作用,增强了焦虑发作的可能性。(5)路径分析结果表明神经质人格是焦虑的主要促发因素,它直接或间接地作用于焦虑。整合的焦虑易感性-应激模型的结构方程的拟合指数分别为:x~2/df(4.64)、GFI(0.98)、CFI(0.93)、IFI(0.90)、RMSEA(0.07)。结论:(1)MASQ及相关的焦虑影响因素的各量表都具有较好的同质性信度、重测信度及构想效度。(2)我们提出了焦虑的易感性-应激理论模式,并在大学生样本中进行了试用,结果满意(3)初步建立了一个符合湖南大学生人群的焦虑的易感性-应激的整合模型,为大学生焦虑的防治提供了实证研究的基础。
    Objective:(1)To develop Chinese translation of mood and anxiety symptom questionnaire(MASQ)and a set of assessments scales about diathesis-stress of anxiety and evaluate their reliability and validity.(2)To test the validity of the vulnerability-stress model of anxiety in Hunan undergraduates.(3)To explore the integrated vulnerability-stress model of anxiety in Hunan undergraduate students.Method:(1)The original version of a set of assessments scales about vulnerability-stress of anxiety was provided by Abela professor in McGill University and these final Chinese version scales were approved by repeated translation and back-translation.645 undergraduate students finished first test in time one.The related vulnerability scales were all retested after three-four weeks in 120-130 students among the first test sample.Six months later retested MASQ.The reliability analysis included the Cronbach’s a coefficient,the mean inter-item correlation coefficient and test-retest reliability(intra-class correlation coefficient).The validity analysis included construct validity(the total scale and subscale inter-correlations and several indexes of the maximum-likelihood confirmatory factor analysis).(2)Path Analysis and Structural Equation Model(SEM)were used to explore integrated vulnerability-stress model of anxiety in Hunan undergraduates.Result:(1)The total Cronbach’s a coefficient of MASQ was 0.93 and Cronbach’sαcoefficient of the subscales were between 0.79-0.92. The mean inter-item correlation coefficient of the total scale was 0.17 and the mean inter-item correlation coefficient of the sub scales were between 0.22-0.41.Test-retest reliability(intra-class correlation coefficient)of the total scale was 0.70 and the subscales of the test-retest reliability were between 0.59-0.71.All of the coefficients were significant.(2)The relation between the total scale of MASQ and the subscales were strong(r>0.6).The confirmatory analysis shows that the index of the four-structure of the MASQ all met the adequacy of fit standards, GFIs≥0.9,CFIs≥0.9,IFIs≥0.9 and RMSEA≤0.1.(3)The reliability and validity of all the related scales were met the adequacy of psychometric. (4)The findings of Multiple Hierarchical Regression Analysis revealed that neuroticism,and the interaction between negative cognition and stress,insecurity attachment and stress,neuroticism and stress,society satisfaction and stress were all significantly predicted anxiety symptoms.(5)The structural equation model for integrated vulnerability-stress model of anxiety analysis indicated neuroticism was the most important vulnerability factor for anxiety.It can influence anxiety symptoms directly or indirectly.(5)The structural equation model for integrated vulnerability-stress model of anxiety analysis wereχ~2/df(4.64)、GFI(0.98)、CFI(0.93)、IFI(0.90)、RMSEA(0.07).Conclusion:(1)MASQ and the related vulnerability factor scales exhibited rightly internal consistency,test-retest consistency and construct validity.(2)The result of this study in Hunan undergraduates affirmed the theory of vulnerability-stress model of anxiety,the vulnerability-stress interaction could incremental significantly power to anxiety symptoms.(3)A integrated vulnerability-stress model of anxiety in Hunan undergraduates was provided and to be confirmed,which can be used for intervention of anxiety in undergraduates.
