家长版医院安全文化问卷的修订及信效度评价

Revision and evaluation of reliability and validity of the parental version of Hospital Survey on Patient Safety Culture

目的修订家长版医院安全文化问卷(Hospital Survey on Patient Safety Culture, HSOPSC)并进行信效度评价,探索其对患儿家长的适用性。方法通过专家函询、预调查编制预试量表,2017 年 11 月— 2018 年2 月,采用方便抽样法选取江苏省3 所三级甲等儿童医院住院患儿家长为施测对象,共发放问卷643 份,回收有效问卷562 份,有效回收率为90.2%。采用临界比值法、相关性分析、同质性检验、探索性因素分析、Cronbach's α系数及重测信度进行条目筛选和信效度检验。结果家长版HSOPSC 14个条目均保留;总问卷的内容效度指数(S-CVI)为0.93;探索性因素分析共提取4个公因子,累计方差贡献率65.001%;问卷总的Cronbach's α系数为0.845;重测信度Cronbach's α系数为0.893。结论家长版 HSOPSC 区分度较好,信效度理想,可作为测量我国患儿家长对医院安全文化认知的测评工具。

Objective To revise the English version of Hospital Survey on Patient Safety Culture (HSOPSC) into Chinese, evaluate the reliability and validity of the questionnaire, and analyze its applicability to parents of pediatric patients. Methods The parental version HSOPSC was formulated based on expert consultation and a pilot study. A total of 643 parents were recruited using convenience sampling method from 3 Class Ⅲ Grade A hospitals in Jiangsu province from November 2017 to February 2018. 562 valid samples were collected with a response rate of 90.2%. Item analysis including critical ratio method, Pearson correlation coefficient, homogeneity check, exploratory factor analysis, Cronbach's α and test-retest reliability coefficient were used to perform item screening and evaluate the reliability and validity of the scale. Results All 14 items of parental version HSOPSC were retained. The scale-content validity index( S-CVI) was 0.93;Exploratory factor analysis indicated that the parental version HSOPSC consisted of 4 factors which explained of 65.001% of total variance;The internal consistency reliability coefficients were 0.845 for total scale;Test-retest reliability coefficient was 0.893 for the total scale. Conclusions The parental version of HSOPSC meet the requirement of psychometrics with good discriminative ability, reliability and validity, which could be used as a tool measuring parents' perspective of hospital safety culture.
