Purpose : This study attempts to facilitate sailors' adaptation to the fleet through examination of support relative to the sailors' depression, stress, and Perceived Organizational Support. Method : 230copies of surveys were distributed to shipboard sailors using convenience sampling, 218 surveys out of the 223 returned were analyzed, and 5 untrustworthy replies were omitted by using the SPSS/WIN 17.0. Result : 214(98.2%) of the subjects were categorized as the non-depressed group, 4(1.8%) fell into the depressed group, and the average stress factor was 2.15, This is labeled as 'unlikely ~ normal',since most of the subjects were in highly perceived organizational support. The perceptions of unhealthiness were different: depression being higher in the perception of the unhealthiness group than in the healthiness group. Smaller ships, perception of the unhealthiness, self-agonizing with no one to turn to, and prevailing household difficulties yielded significantly different levels of stress, being higher in high stress groups than in lower stress group. Higher perceived organizational support came with longer service periods and better health. In the relation of among stress, perceived organizational support,and depression, higher stress resulted in higher depression, and higher perceived organizational support was related to lower depression. Negative correlation could be determined between perceived organizational support and stress. Conclusion : In order to facilitate healthy military service for sailors on board ships, efforts need to be exerted to lower stress and depression and to heighten perceived organizational support, along with the development of policies and institution to support these.
