The present study examined the differences in the psychological wellbeing of 270 Polish (198 female) and 209 South Korean (87 female) students. Specifically, it tested the difference in depressive symptom severity between Polish and Korean students, and how this difference may be accounted for by stress and sensitivity to frustration. Poles and Koreans were chosen for this investigation as they vary in terms of culture with Koreans being more collectivistic and more dependent on social context. It was hypothesized that Koreans will have higher levels of depressive symptom severity than Poles due to the elevated levels of stress and sensitivity to frustration. Participants in both countries completed a set of questionnaires including the PHQ-9 -Patient Health Questionnaire, the STAR -Situational Triggers of Aggressive Responses Scale, and the Perceived Stress Scale -PSS 10. We found that Koreans were more depressed than Poles due to the higher stress levels and sensitivity to frustration. We discuss our study from two culturally distinct perspectives: psychological and philosophical. As this article addresses the problem of frustration and stress with attention to social context of emotional expression (or restraining from it), a philosophical concept of resentment may turn out to be a promising area of further research and interpretation.
