Sex Differences in Intimacy Levels in Best Friendships and Romantic Partnerships

Objectives Close romantic and friendship relationships are crucial for successful survival and reproduction. Both provide emotional support that can have significant effects on an individual’s health and wellbeing, and through this their longer term survival and fitness. Nonetheless, the factors that create and maintain intimacy in close relationships remain unclear. Nor is it entirely clear what differentiates romantic relationships from friendships in these terms. In this paper, we explore which factors most strongly predict intimacy in these two kinds of relationship, and how these differ between the two sexes. Results Aside from best friendships being highly gendered in both sexes, the dynamics of these two types of relationships differ between the sexes. The intimacy of female relationships was influenced by similarity (homophily) in many more factors (notably dependability, kindness, mutual support, sense of humour) than was the case for men. Some factors had opposite effects in the two sexes: gift-giving had a negative effect on women’s friendships and a positive effect on men’s, whereas shared histories had the opposite effect. Conclusion These results confirm and extend previous findings that the dynamics of male and female relationships are very different in ways that may reflect differences in their functions.

When Do Friendships Help Versus Hurt? Perceived Best Friend Victimization and Support as Moderators of Peer Victimization-Related Distress

Although high-quality friendships are presumed to protect peer-victimized adolescents from distress, evidence supporting this claim is mixed. This study investigated whether the protective function of high-quality best friendships for victimized youth varies depending on adolescents’ perceptions of their best friend’s victimization. Among a sample of 1,667 eighth graders, we tested the effects of self-perceived victimization, best friend emotional support, and best friend victimization on depressive symptoms and social anxiety across eighth grade. Perceptions of higher emotional support buffered links between boys’ victimization and depressive symptoms. Perceived emotional support buffered links between girls’ victimization and internalizing symptoms if they viewed their best friend as nonvictimized, but it amplified such associations if they viewed their friend as victimized. These results suggest that although perceptions of best friend emotional support benefit peer-victimized youth, highly intimate friendships between victimized adolescent girls may promote maladaptive coping and increased distress.

Associations of Early Adolescents’ Best Friendships, Peer Groups, and Coolness With Overt and Relational Aggression

This study examined associations of best friend and peer group aggressive characteristics with students’ overt and relational aggression, and whether coolness moderated these associations across the fall and spring of the first year in middle school. Students ( N = 174; 57% females) self-reported best friendship and peer group members, as well as peer-nominated coolness and aggression (overt, relational). Results indicated positive relations of best friend and peer group aggressive characteristics with subsequent aggression, and that coolness moderated these associations. Specifically, non-cool youth had higher levels of subsequent overt and relational aggression with aggressive best friends, but lower levels of later relational aggression when in relationally aggressive peer groups. In contrast, cool youth had lower levels of subsequent relational aggression with relationally aggressive best friends, but higher levels of later relational aggression when in relationally aggressive peer groups. Implications for examining multiple peer contexts and coolness during early adolescence are discussed.

Cross-Sex Best Friendships and the Experience and Expression of Jealousy within Romantic Relationships

This study investigated cross-sex best friendships in the experience and expression of jealousy within romantic relationships. Survey data (N = 346) revealed engaged-to-be-married individuals, compared to single, dating and married individuals, have the most negative attitudes regarding cross-sex best friendships. Results further indicated preventive jealousy experience is a predictor of rival-focused jealousy expression, and reactive jealousy experience is a predictor of both constructive and destructive jealousy expressions. Findings also suggest attitudes toward cross-sex best friendships can mediate the relationship between how jealousy is experienced and expressed in relation to reactive jealousy experience and destructive jealousy expression. Implications are discussed regarding how cross-sex best friendships can adversely affect romantic relationships.

With a little help from your friend

Transactive memory is a system for encoding, storing, and retrieving information between people, where each person has knowledge of the other’s memory. Through two studies, we assessed whether transactive memory occurs in best friendships ( N = 682). Results showed that transactive memory systems (TMSs) do exist in best friendships. Importantly, stronger TMSs are associated with higher friendship quality (satisfaction and commitment), and their strength is related to different friendship characteristics (e.g., trust). A novel method for assessing TMS structure was developed. Mixed-gender friendships were associated with more differentiated structures (different knowledge), and friendships higher in inclusion of other in the self were associated with more integrated structures (similar knowledge). These studies have implications for the quality and operation of friendships.

Sex and Gender as Factors in in Romantic Partnerships and Best Friendships

For the majority of people, two key non-kin figures form part of the central support clique that resides at the centre of their social network. These are the best friend and the romantic partner, and both play distinct roles which are of benefit to the individual concerned. However, while the romantic partner will always have been chosen in the context of the mating market, we do not know whether the selection of a best friend occurs within a similar market of competition and assessment. This study used real self-rated attribute data for participants and their best friends and romantic partners to explore: (1) whether best friendships operate within a mating market; (2) whether, once established, they show evidence for positive illusion, projection or competition; and (3) whether assortative mating is present. Further, we considered whether the sex of the best friend relative to the participant influences these results. We found that same-sex best friends have an acknowledged role linked to social connectedness and behaviour, that for same-sex best friends both male and female participants show evidence for homophily or projection rather than mate competition, that neither male nor female participants appear to view cross-sex best friends as potential mates, and that the evidence for ‘assortative mating’ is stronger within best friendships than romantic partnerships regardless of best friend sex. Our results imply that despite a culture of commitment and monogamy, male participants display behaviours within their romantic partnerships which suggest they are still active within the mating market. In contrast, for both sexes the best friendship is unaffected by the mating market and the stability and contentment that characterises best friendships is underpinned by a degree of similarity stronger than that within the romantic partnership.
