Construction and reliability and validity analysis of satisfaction scale for medical graduates

Objective To construct the satisfaction scale for medical graduates and evaluate its reliability and validity. Methods Totally 2 961 full-time postgraduates from Guangxi Medical University were investigated in September 2017. Exploratory factor analysis was used to construct dimensions and evaluate the validity. Confirmatory factor analysis was used to verify the scale's fitness. Results A total of 31 items were included in the scale. The overall Cronbach's α coefficient was 0.972. Five common factors were extracted by the principal components method and the cumulative contribution rate reached 81.09%. The results of confirmatory factor analysis showed that χ2/df was 4.451 (95%CI=4.321~4.558), root mean square error of approximation (RMSEA) was 0.062 (95%CI=0.058~0.069), other value-added fitness indicators were all over 0.9; the standardized load of each item was over 0.71 and had statistical significance(t>1.96, P<0.05). Conclusions The scale has good reliability, validity and applicability. It can be used as a tool to evaluate satisfaction for medical graduates.
