Objective To translate Parents' Perception of Uncertainty Scale (PPUS) into Chinese,analyze and selected items,and then test the reliability and validity of the Chinese version of PPUS initially.Methods 210 parents of hospitalized children were recruited for the investigation.Frequency analysis,dispersion degree analysis,correlation analysis and so on were applied to analyze and select items.Internal consistency test,Pearson correlation analysis and exploratory factor analysis etc.were applied to test reliability and validity of the scale.Results The final Chinese version of PPUS contained 28 items.The Cronbach α and parity split-half reliability coefficients were 0.844 and 0.835; The Cronbach α coefficient of 4 dimensions ranged from 0.537 to 0.770.The item-total scale correlation coefficient ranged from 0.300 to 0.737.Item-dimension correlation coefficients ranged from 0.376 to 0.762.Item-other dimension correlation coefficients ranged from 0.028 to 0.514.Dimension-total scale correlation coefficients ranged from 0.480 to 0.863 and those between dimensions ranged from 0.226 to 0.536.In the content validity assessed by experts,I-CVI ranged from 0.75 to 1.00,S-CVI/Ave was 0.928.Four-factor model was performed in the principal component analysis and they explained for 41.401％ variances.The maximum factor loading of all items were higher than 0.3,and most of items had adequate loadings in related dimensions.Conclusions Chinese version of PPUS had appropriate reliability and validity as an assessment tool for parental uncertainty in illness of hospitalized children' parents.

Objective To establish a scientific and objective indicator system for nursing quality evaluation according to nursing works of neonatal surgical department. Methods To establish the indicator system based on the three- dimension quality structure. Literature retrieval, expert interview and Delphi expert enquiry were used to filter and improve indicators. Analytic hierarchy process was used to determine the index weight and check the consistency. Results The quality indicator system included three levels. There were 3 indicators in level one, 14 indicators in level two and 70 indicators in level three. Experts coefficient was 0.867, mean of importance values of two rounds were 3.83-5.00 and 4.08-5.00 , Kendall coordination coefficients were 0.292(P<0.01) and 0.301(P<0.01). Conclusions The nursing quality evaluation indicator system has high reliability and it can be used for guiding continuous improvement of nursing in neonatal surgical department.
