Objective We sought to develop Nurse Job Performance Scale and test its validity and reliability.Methods Initial version of Nurse Job Performance Scale was formulated by using literature review and qualitative interview.By cross-sectional investigating of 562 nurses in coastal cities by convenience sampling as well as screening and selecting items through item analysis,the validity and reliability was tested under the statistics.Results Three factors containing 14 items were extracted by using exploratory factor analysis:work coordination,working enthusiasm and work involvement.The average value of factor loading was between 0.643～0.839,the 3 factors explained 73.9％ of the total variance.The total Cronbach's α was 0.937 and the Cronbach's α coefficients of every dimension were between 0.767～0.930.Conclusions Nurse Job Performance Scale has good validity and variability.

ObjectiveTo explore the status of mild cognitive impairment （MCI） among the elderly in Shanghai communities， and to identify the factors associated with MCI. MethodsThe Montreal Cognitive Assessment-Basic （MoCA-B） was used to screen for MCI in elderly adults. Logistic regression analysis was conducted to identify the factors associated with MCI. ResultsAmong 629 participants， 226 （35.90%） were positive for MCI. Older age （OR=1.04， 95%CI： 1.01-1.07）， lower family income （average OR=2.20， 95%CI： 1.01-4.80； poor OR=2.59， 95%CI： 1.03-6.50）， hearing impairment affecting daily life （OR=1.86， 95%CI： 1.19-2.91）， and anxiety symptoms （OR=1.58， 95%CI： 1.02-2.44） were associated with the positive for MCI. Living in central urban area （OR=0.57， 95%CI： 0.37-0.89） and having higher social support （OR=0.97， 95%CI： 0.94-1.00） were protective factors for MCI. ConclusionThe current status of MCI among the elderly in Shanghai communities is not optimistic. It is important and necessary to establish the cognitive-friendly community for the elderly.
