胆石症手术患者生活质量量表的编制策略及条目筛选

Development of Quality of Life Scale Before Operating on Cholelithiasis and Item Selection

目的:编制评价胆石症手术患者生活质量的多维测评量表。方法:采用初始量表对200例将实施胆石症手术的患者进行生活质量的实测后,采用t检验法、相关分析法、因子分析法等5种方法联合进行条目筛选,由保留条目组建量表测试版。结果:①胆石症手术患者生活质量量表(QualityofLifeScaleofoperatingoncholelithiasis,QLSOC)测试版量表由23个条目组成4个维度,其中疾病维度11条目,生理维度4条目,社会维度5条目,心理维度3条目;②条目分析显示测试版量表条目与各维度、总分间的相关分别为0.297～0.868、0.389～0.747;③探索性因素分析抽取6个共因子,累积解释变异量为69.446%,可分属四个维度;④总量表和各维度的Cronbachs’α系数为0.774～0.907。结论:胆石症手术患者生活质量量表的建构基本符合理论构想,达到了编制的要求。

Objective： To develop a self-administered quality of life （QOL） scale for patients before operating for cholelithiasis. Methods： The theory and methodology in developing rating scale were employed to establish the instrument. The QOL data measured from 200 cases before operating for cholelithiasis were used to evaluate the scale. Results： ①Form 23-item Quality of Life Scale before operating for cholelithiasis, including four domains： disease（11 items）, physical（4 items）, social（5 item） and psychological（3 items）. ②The correlation coefficients between items and the scores of the scale and its subscales were 0.297-0.868 and 0.389-0.747 respectively.③Exploratory principal component analysis of the items identified that the scale had six factors that made up four domains, explaining 69.446% of total variance. ④The Cronbach＇s α of total scale and its subscales ranged from 0.774-0.907. Conclusion： The QOLs was developed according to our purpose and meet the need of psychometrics.
