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

Abstract

Objective \nTo 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. \n \n \nMethods \nThe 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 ClassⅢ 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. \n \n \nResults \nAll 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. \n \n \nConclusions \nThe 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. \n \n \nKey words: \nSafety;\xa0Hospital safety culture;\xa0Parents;\xa0Reliability;\xa0Validity
