This study examined the effect of an intervention program for university students on their knowledge of stress and social support, support seeking behavior, perceived social support from family and friends, and stress responses. Participants (n=40) were randomly assigned to either an intervention or a waiting list control group. The program, including psychoeducation seminar (lecture and small group discussion), workbook fulfillment, and follow-up interviews, was conducted for the intervention group for three weeks. Participants (n=15 and n=13 for the intervention and waiting list control groups, respectively) responded to three ways of questionnaire surveys (pre, post and follow-up). The result showed the significant intervention effect for knowledge of stress and social support on the both post and follow-up test. Moreover, the marginally significant intervention effect was found for support seeking behavior on the both post and follow-up test. However, no intervention effects were found for perceived social support from family and friends and stress responses. These results suggest that this program would lead to increase in knowledge of stress and social support and support seeking behavior.
