躯体化症状自评量表的初步编制及信度和效度研究

目的 对躯体化症状自评量表(Somatic Self-rating Scale,SSS)进行信度和效度检验.方法 整群抽取某三甲综合医院各科门诊患者589名、住院患者64名,采用SSS量表进行评测,同时完成Zung's量表评测以检验校标效度,随机抽取24名患者在未服用抗焦虑抑郁药物的情况下2周后进行重测以检验重测信度.结果 SSS量表重测信度0.96(P＜0.01),其内部一致性Cronbach's α系数0.89.总分与各因子的相关系数在0.76～0.88之间,各因子间相关系数在0.56～0.70之间.验证性因素分析的指标:CFI=0.890,NFI=0.856,RFI=0.816,IFI=0.891,TLI=0.859,x2/df=3.67,REMEA=0.064,各条目对因子负荷系数在0.427～0.732之间.SSS总分与焦虑自评量表和抑郁自评量表的相关系数在0.74～0.80之间,各因子分与焦虑、抑郁自评量表的相关系数在0.55～0.74之间.ROC曲线下面积AUC=0.841.结论 躯体化症状自评量表具有较好的信度和效度,可应用于综合医院患者心理症状的筛查.

Developing of somatic self-rating scale and its reliability and validity

Objective To assess the reliability and validity of the Somatic Self-rating Scale(SSS). Methods The sample consisted of 589 outpatients and 64 inpatients, which all the patients completed Zung's Scales at the same time to test criterion validity of the SSS. And 24 inpatients were selected randomly to take a retest after two weeks without antidepressant treatment. Result The test-retest reliability of the SSS was 0.96 and the Cronbach' s αcoefficients was 0.89. The correlation coefficients of the four factors with the total scale score ranged from 0.76 to 0.88, the correlation coefficients of the four factors ranged from 0. 56 to 0.70. The confirmatory factor analysis showed that the fit index for GFI, NFI, NNFI, CFI, IFI were all approaching 0.9, REMEA = 0. 064,x2/df = 3.67. The factor loadings ranged from 0. 427 to 0.732. Correlations with Zung's Scales were in range of 0.74to 0. 80 while the four factors were in range of 0.55 to 0.74. Drawing the ROC curve and the area under the curve was 0.841. Conclusion The SSS has a high reliability and a good validity and can be used in general hospital.
