Attitudes toward consensual non-monogamy predicted by sociosexual behavior and avoidant attachment

Exploring Compersion: A Study on Polish Consensually Non-Monogamous Individuals and Adaptation of the COMPERSe Questionnaire

Compersion is a positive emotion experienced in relation to one's partner's relationship(s) with other partner(s). Experiencing it is highly desired in communities practicing consensual non-monogamy (CNM), especially polyamory. This article presents the results of a study on compersion on Polish CNM individuals. The main goal of the study was to adapt to the Polish-speaking population the COMPERSe (Classifying Our Metamour/Partner Emotional Response Scale; Flicker et al., 2021), the first standardized quantitative scale designed to measure compersion. The analyses were performed on data obtained from 211 individuals in CNM relationships and on a comparative group of 169 people in monogamous relationships. The results of the confirmatory factor analyses suggested that the three-factor model of the original COMPERSe version did not fit well, leading to further revisions that resulted in a 7-item, two-factor solution with excellent fit, excellent internal consistency, strong divergent and convergent validity, and excellent test-retest stability. The CNM individuals were found to have higher scores on compersion and cognitive empathy and were also less jealous than the monogamous participants. Furthermore, polyamorous individuals experienced more compersion and less aversion to partner's autonomy than people in open relationships. It was also revealed that compersion indirectly predicted relationship satisfaction by decreasing jealousy and that compersion was, in turn, predicted by cognitive empathy. However, when polyamorous and open relationships were analyzed separately, compersion predicted relationship satisfaction directly, but only in polyamorous relationships; meanwhile, in open relationships, satisfaction was directly predicted by cognitive empathy.

Multidimensional Measurement of Attitudes Toward Consensual Non-Monogamy

Despite increased interest in consensual non-monogamy (CNM), significant stigma remains against CNM. Consequently, there is a need for scales to assess attitudes toward CNM. In response to this need we developed the Multidimensional Attitudes toward CNM Scale (MACS). Items were developed in consultation with content experts and data were collected from two samples at two different Canadian Universities. Fit indices of exploratory (Sample A) and confirmatory (Sample B) factor analysis suggested a 16-item scale with three underlying factors: CNM is Dysfunctional, CNM is Immoral, and CNM is Healthy and Satisfying. Validity analyses, conducted using the combined sample (n = 806; 79% women; 67% heterosexual), demonstrated that participants with higher MACS total scores (i.e. more negative attitudes) were less likely to have ever been involved in a CNM relationship and were more likely to report monogamy as their ideal relationship style. Higher MACS scores were also associated with more negative attitudes toward bisexuality and toward women, and higher scores on measures of homophobia and jealousy. In contrast, individuals with higher scores on the CNM is Healthy subscale tended to score higher on measures of empathy. The MACS demonstrates strong psychometric properties and can assist in better understanding attitudes toward CNM relationships in research and clinical settings.

Polygamous Interest in a Mononormative Nation: The Roles of Sex and Sociosexuality in Polygamous Interest in a Heterosexual Sample from the UK

Polygamy is a form of "one-sided" consensually non-monogamous relationship where one person has multiple committed partners, each of whom is only involved with that one person. It was likely a reoccurring feature of ancestral mating that posed adaptive problems for our ancestors. Yet polygamy, and multi-partnering more generally, is understudied in Western cultures, raising questions about the existence of polygamous interest and whether this is calibrated adaptively to personal conditions. In two studies, we examined polygamous interest in two heterosexual online samples from the UK. In Study 1 (N = 393), modest interest was found for polygamous relationships overall. Men were six times more open to polygyny than women, but there was little sex difference in openness to polyandry. Further analysis revealed that all forms of multi-partnering were undesirable relative to singlehood and monogamy; however, consensual multi-partner relationships were less undesirable than non-consensual ones. Sex differences were largest for polygyny and arrangements where men had agreed access to a casual partner alongside a committed one, yet these were two of the most acceptable forms of multi-partnering when men and women's responses were combined. Sociosexuality positively predicted interest in most forms of multi-partnering. Study 2 (N = 735) focused on polygyny and added status-linked traits as predictors. The results of Study 1 were broadly replicated, though the status-linked traits did not predict polygynous interest specifically. Instead, sociosexuality and male intrasexual competitiveness uniquely predicted general interest in multi-partner relationships. Overall, interest in polygamy appears to emerge despite social discouragement and sex differences in interest track the relative costs and benefits associated with it. However, there is no strong evidence that polygamous interest is uniquely calibrated to personal conditions when compared to other forms of multi-partnering.

What do we know about consensual non-monogamy?

Recent years have seen considerable interest in consensual non-monogamy from both public and academic perspectives. At least 5% of the North American population is currently in a consensually non-monogamous relationship of some form and there is little difference in measures of relationship quality compared to monogamous relationships. Despite increasing levels of understanding and engagement many practitioners of consensual non-monogamy still experience stigma (and minority stress) which is exacerbated by context (e.g. parenting, healthcare settings), type of consensual non-monogamy (e.g. polyamory vs swinging) and intersects with other identities (e.g. race, sexuality). This review outlines what is currently understood about consensual non-monogamy and argues that relationship diversity has a place alongside gender and sexuality when studying sexual behaviours, romantic relationships, and well-being.
