This study examined theoretical relationships among the three stress-related. variables:(1) perceived pressure of time for the school and hospital responsibilities as stressors, (2) job satisfaction, psychophisical exhausion, and school-life satisfaction as strain measures, and (3) a number of friends in school and hospital support for attending school as social support measures. Perceived shortage of time highly correlated with two strain measures: psychophisical exhausion and job satisfaction with working conditions. Hospital support for attending school highly correlated with all of the strain measures. A moderating effect of social support on the relationship between the time shortage and strain measures showed two different patterns, reflecting the differetial quality of social support measures (as moderators). One result obtained using hospital support as a moderator confirmed the hypothesis on the stress buffering effect. When a number of friends was employed as a moderator, students with both fewer and moderate number of friends confirmed the stress buffering hypothesis, but for the students with a large number of friends the result showed disagreement with this hypothesis. As a conclusion, implications of the findings of this sutdy, especially of those regarding the social support effects were discussed for practices of the nurse education and development at the work place.
