Based on the assumption that cultural orientations affect interpersonal conflicts, the study examined conflict styles across two national cultures of neighboring European countries, i.e. Lithuania and Poland. Whereas Poland and Lithuania score relatively high in terms of individualism, they differ in terms of power distance, uncertainty avoidance, and masculinity-femininity. For the research purposes, a conflict resolving style questionnaire was applied, which was prepared by T. Wach according to the Thomas-Kilmann Conflict Mode Instrument. The questionnaire was administered to 520 participants aged 13–15. Conflict style comparisons demonstrated that the Lithuanians chose dominating and accommodating styles more often than the Polish did, and the Polish chose integrating more often than the Lithuanians. The research findings can be a valuable source in predicting conflict resolution patterns.
