| OBJECTIVETo explore the constituent elements of nurses'organizational climate, and develop a standardized scale for measuring Chinese nurses'perceptional organizational climate in the hospital. Reliability and validity of the scale were tested to provide a scientific and objective evaluation tool for both nurse leaders and future studies.METHODSTwo steps were taken in this study. First, the development of nurses'organizational climate scale was based on the framework of Stone for the Integrative Model of Organizational Climate (IMOC). According to literature review and semi-structure interviewing, item pool was established, and then screened by specialists. A total of 480 clinical nurses were tested and the items were re-screened by such indexes as item discrimination, spearman correlation analysis, exploratory factor analysis, Cronbach'sɑcoefficient and so on. A preliminary scale consisting of six factors with 37 items was developed. Second, the scale was validated on a sample of 706 clinical nurses , confirmatory factor analysis(CFA) and actual validity analysis were carried out to verify the conceptual model. Data was collected and analyzed by SPSS15.0 and AMOS 7.0.RESULTS1 The scale was finalized with six components including 37 items. The six components including adequate resources, team behavior, management support, quality control, human resources management and evidence-based nursing support.2 Item analysis: The decision values of each item (P<0.001) and the correlation coefficients between each item and total score (P<0.001) were statistically significant. With the deleted items whose correlation coefficient was lower than 0.4, and the D value lower than 2.0, the degree of differentiation of each item is good.3 Reliability verfication: (l)The retest reliability: coefficients for subscales ranged from 0.614 to 0.801, and 0.813 for the total scale; (2)Split-half reliability coefficients were 0.738~0.868 for subscales, and 0.902 for total scale; (3)Cronbach'sαcoefficient: 0.745~0.877 for subscales, and 0.939 for total scale; (4)The consistency of item tables: the correlation coefficients between each item and each subscale were 0.547~0.911, the correlation coefficients of each subscale were 0.323～0.672, and the correlation coefficients between each subscales and total scale were 0.682～0.809, and there were statistical significance in all of them (P<0.01).4 Validity verification: (l)Structure validity: extracted six first-order factors which account for 54.653% of the accumulated variance; extracted one second-order factor which accounts for 55.146%;χ~2,df,χ~2/df,NFI,RFI,IFI,TLI,CFI,RMSEA,GFI,AGFI,SRMR,PNFI,PGFI in the first-order and second-order factors were all acceptable; (2)Criterion-related validity: There was significantly negative correlation between the nurses'perception of organizational climate and emotional exhaustion, and turnover intention (P<0.01), the correlation coefficients were 0.604, 0.572, respectively.CONCLUSIONThe nurse's organizational climate scale meets the requirement of psychometrics with a good degree of discrimination. The index of reliability achieves the demand of psychometrics; The structure validity is good and tallies with the design plan; Psychometric properties analysis shows that the scale is a reliable, consistent and effective instrument for the assessment of nurse's organizational climate in China, and the scale can be used to explain the status and characteristic of nurses'organizational enviornment. More researches should be taken for further confirmation of the scale.
