焦虑敏感问卷中文版对焦虑障碍患者测试的信度和效度

目的 测试焦虑敏感问卷中文修订版(ASI-CR)应用于焦虑障碍患者中的信度与效度.方法 以ASFCR、特质焦虑问卷(T-AI)、汉密尔顿焦虑量表(HAMA)和焦虑敏感测定量表(ASI-R)调查焦虑障碍患者68例,检验ASI-CR的信度和效度.结果 整个问卷及各因子的内部一致性系数为0.77～0.89,分半信度为0.67～0.88.因子间的相关系数为0.51～0.65,因子与ASI-CR总分之间的相关系数为0.83～0.89,各因子内部的相关系数为0.60～0.90. ASI-CR总分及3个因子分与ASFR总分相关系数为0.76～0.97,ASI-CR 3个因子分与ASI-R中对应的因子分相关系数为0.78～0.97.焦虑障碍患者在ASI-CR总分及“对生理唤醒的恐惧”因子分、“对认知失控的恐惧”因子分均高于中学生常模,差异有统计学意义(P＜0.01).探索性因子分析示3个因子的累积贡献率为65.06％,条目的因子负荷率为0.51～0.88,但因子间条目分布不均,“对认知失控的恐惧”因子中2个条目负荷过低(0.22、0.48).结论 ASI-CR用于焦虑障碍患者有较好的信度、效标效度和内容效度,但结构效度尚待进一步修订完善.

Reliability and validity of Chinese revision of anxiety sensitivity index-revised among patients with anxiety disorders

ObjectiveTo evaluate the reliability and validity of the Chinese version of the anxiety sensitivity index-revised(ASI-CR) among patients with anxiety disorders. MethodsA total of 68 patients with anxiety disorders were interviewed using anxiety sensitivity index-revised (ASI-R), trait anxiety inventory (T-AI), Hamilton anxiety scale (HAMA) and ASI-CR; the reliability and validity of ASI-CR were examined. ResultsInternal consistency of ASI-CR and each factor was 0.77-0.89 and the split-half reliability was 0.67-0.88. The internal correlation coefficient between factors was 0.51-0.65, the correlation coefficient between factors and the total score was 0.83-0.89, and internal correlation coefficient among factors was 0.60-0.90. The correlation coefficient between the total score and factor scores of ASI-CR and total score of ASI-R was 0.76-0.97, and the correlation coefficient between factor scores of ASI-CR and corresponding factor score of ASI-R was 0.78-0.97. The total score and two factor (physical concern and cognitive concern) score of ASI-CR in anxiety patients were significantly higher than the norm (P<0.01). Exploratory factor analysis revealed that the three lower-order ASI-CR factors contributed 65.06% of the total variance. Factor loading of items was 0.51-0.88, but the items were unevenly distributed among factors. Two items had low loading to cognitive concern factor (0.22, 0.48). ConclusionThe ASI-CR displays satisfactory reliability, criterion validity and content validity among anxiety patients, but further research is needed to improve its structural validity.
