Does “open” rhyme with “special”? Comparing personality, sexual satisfaction, dominance and jealousy of monogamous and non-monogamous practitioners
Romantic relationships are changing in Western culture. The recent rises of alternative relationship models called consensual non-monogamies (CNMs) like polyamory, relational anarchy or open relationships have drawn some attention towards them. However, the psychological characteristics of non-monogamous practitioners have not yet been investigated and compared to monogamous practitioners, mainly for being a hard to reach population. In this study, 372 participants (with 193 hard-to-reach non-monogamous practitioners) were assessed in their relational style and compared in personality, sexual satisfaction, dominance, and jealousy. On most investigated dimensions, monogamous and non-monogamous participants did not significantly differ from each other. However, non-monogamous practitioners were significantly more open, less conscientious, and also experienced more dominance by their partner, which provided mixed evidence to the study hypotheses. Possible psychological and methodological explanations were outlined. In addition, these significant differences were small, thereby needed to be taken with caution. These differences could not be explained by differences in age, gender, education, marital status, sexual orientation or other measured variables. Since only a few small differences between monogamous and non-monogamous participants were found, this study suggests that monogamous and non-monogamous practitioners are psychologically not different overall. Methodological limitations and future recommendations were assessed and provided, with particular emphasis on replication studies.
