Satisfaction in interpersonal interactions as a function of similarity in level of dysphoria.

This study compared dysphoric and nondysphoric male and female undergraduates as they conversed with dysphoric or nondysphoric undergraduates of the same sex. Subjects rated their satisfaction with the conversation after each turn. The results showed that people in homogeneous dyads (i.e., both partners were dysphoric or both partners were nondysphoric) were more satisfied with the interaction, and their satisfaction increased as the conversation proceeded. People in mixed dyads were less satisfied, perceived each other as colder, and spoke about increasingly negative topics. Thus, in accord with other research showing that similarity leads to liking, the crucial determinant of interactional satisfaction was neither the mood of the subject nor the mood of the partner, but their similarity in mood.
