精神障碍患者社会功能缺损评定量表的信效度分析

目的 检测精神障碍患者社会功能缺损评定量表(SSFD-MD)的信度和效度.方法 对1003例精神残疾鉴定患者施测,其中100例患者相隔1个月进行重测,并由2名熟悉SSFD-MD评分细则的评定人背对背测评.对其中300例同时实测社会功能缺陷筛选量表(SDSS)、住院精神病人社会功能评定量表(SSPI)、精神功能大体评定昔表(GAF)、简明精神病评定量表(BPRS)、世界卫生组织残疾评定量表Ⅱ(WHO-DASⅡ)、成人智残评定量表(ARSMD)及锥体外系副反应量表(RSESE).结果 ①信度:全量表总分及各分量表的Cronbach's α系数均大于0.90;各分量表及总分重测一致性在0.67～0.83之间;评分者信度在0.87～0.97之间.②效度:各分量表间的相关系数在0.46～0.74之间,各分量表与总分的相关系数在0.73～0.87之间,均具有显著性(P＜0.01);经方差最大化正交旋转后全量表提取5个主成分,累计解释的总变异为82.25%.SSFD-MD与SDSS、SSPI及GAF呈高度相关,分别为0.71,0.72和0.78;与BPRS、WHO-DASⅡ及成人智残评定量表呈中度相关,r分别为0.62,0.50与0.46;与锥体外系副反应量表(RSE-SE)呈低度相关(0.22),均差异具有显著性(P＜0.01).结论 SSFD-MD编制符合心理测量学的基本要求,具有良好的信度和效度.

Abstract：

Objective To test the reliability and validity of the rating scale of social function deficit due to mental disorders (SSFD-MD). Methods 1003 cases with mental disability evaluation were tested by SSFDMD. At sametime, 100 cases of 1003 cases were test-retested and back to back tested by two examiners. 300 cases of 1003 cases also were tested by social disability screening schedule( SDSS),scale of social function for psychosis inpatients(SSPI),global assessment function(GAF) ,the brief psychiatric rating scale(BPRS) ,WH0 disability assessment scale Ⅱ (WHO-DASⅡ ), adult rating scale of mentally disabled ( ARSMD) and rating scale for extrapyramidal side effects (RSESE). Results ①The Cronbach's α coefficients of the total score and all dimensions of SSFD-MD were more than 0.90. The test-retest reliability ranged from 0.67～0. 83 ,and the scorer reliability were 0. 87～0.97. ②The correlations between item scores ranged from 0.46 ～0.74(P＜0.01). The correlations between the factor scores and the total scores ranged from 0.73～0.87(P＜0.01). To extract five full-scale principal components after orthogonal rotation to maximize variance,the cumulative total variance explained was 82.25%.There were highly correlations between SSFD-MD and SDSS.SSPI and GAF,respectively ( r = 0. 71,0.72 and 0. 78). There were moderate correlations between SSFD-MD and BPRS WHO-DAS II ARSMD,respectively(0.62,0. 50 and 0.46). There was a low correlations between SSFD-MD and RSESE ( r = 0.22) ,but all correlations were significant(P＜0.01). Conclusion SSFD-MD has acceptable psychometrics properties on reliability and validity.
