Objective To investigate the feasibility of Six Dimensions Scale (6-D scale) of Nursing Performance used for evaluating the effect of standardized hospital-department training on new graduate nurses.Methods 6-D Scale of Nursing Performance was conducted to evaluate the nursing ability of 216 new graduate nurses (2013) of our hospital pre and post the three-month intervention,including the self-appraisal and appraisals by head nurses.Results The nursing ability was improved significantly after the training.The total score of self-appraisal 6-D scale were significantly higher than that before the training (142.34±19.92 vs 135.81±18.30),in which the subscales scores within the dimensions of leader-ship,critical care,teaching/collaboration,planning/evaluation,interpersonal relations/communication were increased significantly,while the increase of professional development was not significant.Six-D Scale and six subscales scores based on self-appraisal were higher than that based on the head nurses' appraisals.Conclusions The application of 6-D scale is scientific to evaluate the effect of standardized nurse training.We had demonstrated that standardized hospital-department training is of great benefit for new graduates to improve the nursing ability and adapt to the clinical circumstances.
