Strategies of humans with stress are divided into two major groups by means of the stress coping inventory (SCI) after Lazarus, i.e. an emotion-focused type (E-type) and a problem-focused type (C-type). We have examined whether responses to stress were different between college students with these two coping strategies. By means of SCI, coping styles of the college students volunteered were divided either into E-type or C-type. Cardiovascular and mucus immune responses to stress were compared between two groups. Waiting still for a sentence-completion test was regarded as an acute, passive stress. The secretion of secretory immunoglobulin A(sIgA) was decreased by the stress both in E-type and C-type students. However, covariance of heart beat intervals (CVPP) was decreased by the stress in C-type students but not in E-type students. A decrease in finger skin temperature, i.e. vasoconstriction of the cutaneous vasculatures, was observed only in C-type students. There was no difference in subjective reports on the strength of stress between two groups. In conclusion, acute, passive stress induced cardiovascular responses predominantly in C-type students, although caused a decrease in sIgA secretion both in E-type and C-type students. By these results, we have confirmed that stress responses are different between humans with different coping strategies with stress. [Jpn J Physiol 55 Suppl:S225 (2005)]
