Sheehan残疾量表在美沙酮维持治疗门诊患者中应用的信效度研究

RELIABILITY AND VALIDITY OF SHEEHAN DISABILITY SCALE FOR OUTPATIENTS RECEIVING METHADONE MAINTENANCE TREATMENT

目的:研究Sheehan残疾量表(Sheehan Disability Scale,SDS)在美沙酮维持治疗门诊患者中使用的信度和效度。方法:选择武汉市第一健康门诊的188名美沙酮维持治疗患者完成30天功能问卷、SDS和世界卫生组织生存质量测定量表简表(WHOQOL-BREF),间隔1周后对其中50名患者进行SDS重测。采用相关分析评价量表的信度和效度。结果:SDS三个项目与总分之间的相关系数在0.90-0.93之间(P<0.01),平均相关系数为0.91,项目区分度指数在0.65-0.74之间。量表的Cronbachα系数为0.91,重测信度为0.85(P<0.001),与WHOQOL-BREF自评总分校标关联效度为-0.58(P<0.01)。结论:SDS在美沙酮维持治疗门诊患者中使用具有较好的信度和效度。

Objective ： To examine the reliability and validity of Sheehan Disability Scale （SDS） for outpatients receiving methadone maintenance treatment （MMT）. Methods：One hundred and eighty - eight MMT outpatients from Wuhan First Health Clinic were assessed with 30 - Day Function Questionnaire, SDS and the Brief Version of the World Health Organization＇ s Quality of Life Questionnaire （ WHOQOL - BREF）. Fifty outpatients were re -assessed with SDS one week later. Spearman correlation analysis was used to determine the reliability and validity. Results ： Item - total score correlations were between 0. 90 and 0. 93 （P 〈 0. 01 ）, the average correlation was 0.91, and the index of discrimination ranged between 0. 65 -0. 74. The Cronbach α coefficient was 0. 91, the re - test reliability was 0. 85（P 〈0. 001 ） and the criterion related validity with WHOQOL - BREF general quality of life item score was - 0.58 （ P 〈 0. 01 ）. Conclusion ：sheehan Disability Scale has good reliability and validity for MMT outpatients.
