Mean scores of internal marketing factors in nursing organization were as follows; horizontal communication 3.42, downward communication 3.32, involvement communication 3.08, upward communication 3.00, education training 2.54, welfare 2.51. The mean score of job satisfaction was 2.79 and organizational commitment was 3.00. 2. Job satisfaction was positively correlated with education training (r=0.54, p=0.0001), upward communication(r=0.49, p=0.0001). welfare (r=0.40, p=0.0001), horizontal communication(r=0.33, p=0.0001), involvement communication(r=0.25, p=0.0001) of internal marketing factors in nursing organization, but negatively correlated with downward communication(r=-0.16. p=0.0082). Organizational commitment was positively correlated with upward communication(r=0.48, p=0.0001), education training (r=0.42, p=0.0001), horizontal communication(r=0.36, p=0.0001), welfare (r=0.34, p=0.0001), involvement communication(r=0.25, p=0.0001) of internal marketing factors in nursing organization. but negatively correlated with downward communication(r=-0.20, p=0.0014).
