Estimates and correlates of engagement in consensually non-monogamous relationships
Interest in consensually non-monogamous (CNM) relationships—in which partners have explicitly agr... more Interest in consensually non-monogamous (CNM) relationships—in which partners have explicitly agreed that pursuing other romantic or sexual partners is permitted—has grown both among the American public and among researchers and practitioners. Yet, little is known about the prevalence of CNM relationships or factors related to engagement in these relationships. In this review, we synthesize the past 5 years of research on CNM relationships to provide insight on (1) definitions of differing CNM relationships, (2) how many people are engaging in or have previously engaged in CNM relationships, and (3) which social identities and individual differences are associated with CNM engagement. Engagement in CNM relationships has been linked to positive aspects of sexual health such as open conversations about sexual needs and risk, and greater condom use. Researchers and practitioners should further address perceptions of and approaches to relationships outside the standard of monogamy.

Using two separate U.S. Census based quota samples of single adults in the United States (Study 1: n = 3,905; Study 2: n = 4,813), the present studies show that more than one in five (21.9% in Study 1; 21.2% in Study 2) participants report engaging in CNM at some point in their lifetime. This proportion remained constant across age, education level, income, religion, region, political affiliation, and race, but varied with gender and sexual orientation. Specifically, men (compared to women) and people who identify as gay, lesbian, or bisexual (compared to those who identify as heterosexual) were more likely to report previous engagement in CNM. These findings

The association between spirituality and emotional health has been well documented in healthy individuals. A small literature has shown that spirituality plays a role in well-being for some breast cancer (BC) survivors; however, this link is virtually unexplored in partners/spouses of survivors. The current study aimed to assess the relationship between spirituality, emotional distress, and post-traumatic growth for BC survivors and their partners using a dyadic analyses approach.
Methods
A total of 498 couples who were 3–8 years post-BC diagnosis were recruited from the Eastern Oncology Group database.
Results
For BC survivors and their partners, greater levels of spirituality were associated with increases in their own post-traumatic growth. There was no relation between BC and partner spirituality and their own emotional distress, but partner's spirituality was associated with reduced occurrence of intrusive thoughts in the BC survivor. In contrast, BC survivors' spirituality was found to be wholly unrelated to partner's mental health and adjustment.
Conclusions
Following diagnosis and treatment, spirituality appears to associate with positive growth in BC survivors and their partners. However, BC survivor and partner spirituality seem to be ineffective at impacting the other's post-traumatic growth or emotional distress, with the exception of intrusive thoughts. Dyadic analysis takes into account the reciprocal influence of close relationships on health and is an important and under-utilized methodology in behavioral oncology research and clinical practice.

Romantic and dating behaviors among single parents in the United States

Using data collected from a nationally representative U.S. probability sample of single adults, we provide findings on dating attitudes and behaviors among 747 single parents in the United States, aged 21 years and older, who had one or more children under the age of 18 years. Findings show gender differences between single men and single women concerning how they balance being a single parent and make time for dating. Both single fathers and single mothers considered their child's opinion about their dating life, and most parents involved their child(ren) once they knew they wanted or had established a committed romantic relationship with a new partner.

Research on sexting has focussed on youth, with limited data across demographics and with little known about the sharing of private sexual images and messages with third parties. Methods: The present study examines sexting attitudes and behaviours, including sending, receiving, and sharing of sexual messages and images, across gender, age, and sexual orientation. A total of 5805 single adults were included in the study (2830 women; 2975 men), ranging in age from 21 to 75+ years. Results: Overall, 21% of participants reported sending and 28% reported receiving sexually explicit text messages; both sending and receiving 'sexts' was most common among younger respondents. Although 73.2% of participants reported discomfort with unauthorised sharing of sexts beyond the intended recipient, of those who had received sext images, 22.9% reported sharing them with others (on average with 3.17 friends). Participants also reported concern about the potential consequences of sexting on their social lives, careers, and psychosocial wellbeing. Conclusion: Views on the impact of sexting on reputation suggest a contemporary struggle to reconcile digital eroticism with real-world consequences. These findings suggest a need for future research into negotiations of sexting motivations, risks, and rewards.

Forty-five heterosexual undergraduate couples (N = 90) reported measures of the Dark Triad and relationship commitment and satisfaction. Within couples, assortative mating was slightly negative for narcissism, marginally positive for Machiavellianism, and significantly positive for psychopathy. Using actor-partner interdependence models, we explored the extent to which satisfaction mediated the direct associations between the Dark Triad and commitment. Men's satisfaction marginally mediated the women's Dark Triad ? men's commitment negative association. Among the three Dark Triad subscales, satisfaction marginally mediated both of the actor-effect-based psychopathy ? commitment negative associations. We discuss possible implications for couples' relationship strategies.

Drawing on inclusive fitness theory (Hamilton, 1964) and the Kinship, Acceptance, and Rejection Model of Altruism and Aggression (KARMAA; Webster, 2008; Webster et al., 2012), we designed a 2 (participant gender) × 2 (target gender) × 2 (insult: status vs. reproductive) × 3 (relatedness: stranger vs. cousin vs. sibling) between-person experiment in which 489 participants (a) read vignettes in which a stranger, cousin, or sibling was insulted and (b) reported their emotional reaction and retaliation likelihood (six-item α = .91) in response to the insult. Consistent with theory and prior research, men were significantly more aggressive than women, and people were significantly more aggressive responding to insults against kin than non-kin. These...

A life history theory of father absence and menarche: a meta-analysis

Drawing on evolutionary psychology and life history theory, prior research has suggested such a relationship (Belsky, Steinberg, and Draper, 1991; Draper and Harpending, 1982; Ellis, 2004). Although qualitative reviews have shown narrative support for this relationship (Allison and Hyde, 2013; Ellis, 2004; Kim, Smith, and Palermiti, 1997; Susman and Dorn, 2009), no quantitative review exists to provide empirical support for this relationship or to explain mixed results. Thus, we conducted a random-effects meta-analysis of correlations (Card, 2012) on father absence and daughter menarcheal age (k=33; N=70,403). The weighted mean correlation was .14, 95% CI [.09, .19], suggesting that father absence was significantly related to earlier menarche; effect sizes were heterogeneous. Egger's regression (Egger, Smith, Schneider, and Minder, 1997) showed no evidence of publication bias (file-draw...

Across studies, empathy was assessed after reading a pain-related narrative of either a 25-or 85-year-old target and again after assignment to one of two recall conditions. Conditions involved recalling a pain-related autobiographical memory (Studies 1 and 2), or as comparisons, recalling the target's pain narrative (Study 1) or recalling a character in pain from a movie (Study 2). Looking across both studies, empathy levels appear to increase after sharing an autobiographical memory but not in the comparison conditions. Increases in empathy were related to trait-level agreeableness. When target-age differences emerged (Study 2), participants felt greater empathy for the older person. Findings are discussed in terms of the function of autobiographical memory in eliciting pro-social emotions such as empathy and implications for training empathic responding.

Methods: Behavioral data and salivary samples were collected from 19 women during semi-structured interviews. Results: Findings demonstrate substantial individual differences in the magnitude and direction of women's hormonal changes following sexual activity. Conclusions: In an age of individualized medicine, these findings highlight the need to better understand factors shaping variation in physiological responses to sexual activity. Findings contribute to a relatively small and contradictory literature on women's hormonal responses to sexual stimuli.
