Global Ecology and Geography of Gender Equality.

Proximal socio-economic drivers of gender equality tend to obscure its remote ecological origins. General systems theory predicts that the greater annual variability in daylength, temperature, and daily precipitation at higher latitudes requires greater psychosocial flexibility. We extend this prediction to gender equality as a likely consequence. Accordingly, for 87 pre-industrial societies after 1500 CE, we find more gender equality in more variable habitats, and that this link is mediated by greater subsistence flexibility-foraging rather than raising plants and animals. Mutatis mutandis, these ecological predictors of global gender equality replicate in 175 modern countries after 2000 CE. Gender equality was, and still is, lowest around the Equator, higher toward the North and South Poles, and invariant in east-west direction. The geographical positioning of gender equality in pre-industrial times can predict over 40% of the opposite north-south gradients of gender equality in the opposite Northern and Southern Hemispheres today.

Changes in Relationship Commitment Across the Transition to Parenthood: Pre-pregnancy Happiness as a Protective Resource.

The transition to parenthood is both a joyous and a challenging event in a relationship. Studies to date have found mostly negative effects of the birth of the first child on the parental relationship. We propose that partners' pre-pregnancy individual happiness may serve as a buffer against these negative effects. We predicted that parents who are happy prior to pregnancy fare better in terms of relationship commitment after childbirth than unhappy parents. To test our prediction, we used data of a 5-wave longitudinal study among 109 Dutch newlywed couples who had their first child during the study and a comparison group of 55 couples who remained childless. We found that the relationship commitment of fathers with higher pre-pregnancy happiness and fathers with a partner with higher pre-pregnancy happiness increased slightly in the years after childbirth, whereas the relationship commitment of fathers with lower pre-pregnancy happiness and fathers with a partner with lower pre-pregnancy happiness decreased. In addition, the relationship commitment of mothers with a happier partner prior to pregnancy decreased only slightly across the transition to parenthood but showed a steeper decline for mothers with a partner with average or lower pre-pregnancy happiness. In line with the idea that happiness acts as a resource when partners have to deal with relationship challenges, individual happiness predicted changes in relationship commitment for parents, but not for partners who remained childless.

Predictors of forgiveness among divorced parents.

Forgiveness is crucial for establishing coparenting relationships following divorce, yet little is known about the predictors of forgiveness after divorce. In 2 studies, we explore dispositional and divorce-specific factors that correlate with ex-partner forgiveness. In Study 1, we used data from a convenience sample of 136 divorced parents. In Study 2, we used a clinical sample of 165 parents involved in a complex (high-conflict) divorce, who were referred to treatment because of the threat their conflicts posed to their children's well-being. Across samples, forgiveness was negatively associated with conflict severity, narcissistic entitlement, hostile attributions, and traumatic impact of the divorce, and positively with trust and acceptance of the divorce. The main predictors of forgiveness in both samples were more acceptance of the divorce and less narcissistic entitlement. Forgiveness was unrelated to dispositional self-control and trait anger in either sample. We found no evidence of cross-partner effects in Study 2, except for women's hostile attributions on men's forgiveness. Theoretical and practical implications are discussed.

Machine learning uncovers the most robust self-report predictors of relationship quality across 43 longitudinal couples studies.

Given the powerful implications of relationship quality for health and well-being, a central mission of relationship science is explaining why some romantic relationships thrive more than others. This large-scale project used machine learning (i.e., Random Forests) to 1) quantify the extent to which relationship quality is predictable and 2) identify which constructs reliably predict relationship quality. Across 43 dyadic longitudinal datasets from 29 laboratories, the top relationship-specific predictors of relationship quality were perceived-partner commitment, appreciation, sexual satisfaction, perceived-partner satisfaction, and conflict. The top individual-difference predictors were life satisfaction, negative affect, depression, attachment avoidance, and attachment anxiety. Overall, relationship-specific variables predicted up to 45% of variance at baseline, and up to 18% of variance at the end of each study. Individual differences also performed well (21% and 12%, respectively). Actor-reported variables (i.e., own relationship-specific and individual-difference variables) predicted two to four times more variance than partner-reported variables (i.e., the partner's ratings on those variables). Importantly, individual differences and partner reports had no predictive effects beyond actor-reported relationship-specific variables alone. These findings imply that the sum of all individual differences and partner experiences exert their influence on relationship quality via a person's own relationship-specific experiences, and effects due to moderation by individual differences and moderation by partner-reports may be quite small. Finally, relationship-quality change (i.e., increases or decreases in relationship quality over the course of a study) was largely unpredictable from any combination of self-report variables. This collective effort should guide future models of relationships.

A Dyadic Test of the Association Between Trait Self-Control and Romantic Relationship Satisfaction.

Previous research has demonstrated that trait self-control is related to a range of positive romantic relationship processes, suggesting that trait self-control should be positively and robustly linked to relationship satisfaction in both partners in a romantic relationship. However, the existing empirical evidence is limited and mixed, especially regarding partner effects (i.e., the effect of one's self-control on the partner's relationship satisfaction). With three datasets of heterosexual couples (S1: N = 195 newlyweds, longitudinal; S2: N = 249 couples who transition into first parenthood, longitudinal; S3: N = 929 couples, cross-sectional), the present pre-registered studies examined: (1) the dyadic associations between trait self-control and relationship satisfaction both cross-sectionally and longitudinally, and (2) whether these effects hold when controlling for both partners' relationship commitment. The results indicated a cross-sectional positive actor effect, some support for a positive cross-sectional partner effect, and only little support for a longitudinal actor (but not partner) effect. After controlling for relationship commitment, all effects of trait self-control on satisfaction diminished except for a longitudinal actor effect among women in Study 2. Potential explanations for the current results, and implications for theory and practice, are discussed.

Autonomy in Relatedness: How Need Fulfillment Interacts in Close Relationships.

A driving force of relationship maintenance is the fulfillment of basic psychological needs, in particular, the needs for relatedness and autonomy. Until now, research has considered the fulfillment of relatedness and autonomy needs as independent determinants of relationship functioning or as one merged construct called need fulfillment. Little is known about how motivational states interact, even though partners possess and pursue multiple needs at a time in everyday life. Combining theoretical insights from self-determination theory and family systems theory, we test the hypothesis that relatedness and autonomy need fulfillment interact to affect relationship maintenance behavior. In three studies (N = 388, N = 241, and N = 220), we found that relatedness was positively related to accommodation, but especially (or only) when participants reported high, rather than low, autonomy. This research emphasizes the importance of maintaining a sense of self while being closely connected to the partner.

Work-family enrichment, work-family conflict, and marital satisfaction: a dyadic analysis.

This study was designed to examine whether spouses' work-to-family (WF) enrichment experiences account for their own and their partner's marital satisfaction, beyond the effects of WF conflict. Data were collected from both partners of 215 dual-earner couples with children. As hypothesized, structural equation modeling revealed that WF enrichment experiences accounted for variance in individuals' marital satisfaction, over and above WF conflict. In line with our predictions, this positive link between individuals' WF enrichment and their marital satisfaction was mediated by more positive marital behavior, and more positive perceptions of the partner's behavior. Furthermore, evidence for crossover was found. Husbands who experienced more WF enrichment were found to show more marital positivity (according to their wives), which related to increased marital satisfaction in their wives. No evidence of such a crossover effect from wives to husbands was found. The current findings not only highlight the added value of studying positive spillover and crossover effects of work into the marriage, but also suggest that positive spillover and crossover effects on marital satisfaction might be stronger than negative spillover and crossover are. These results imply that organizational initiatives of increasing job enrichment may make employees' marital life happier and can contribute to a happy, healthy, and high-performing workforce.

Workload and the trajectory of marital satisfaction in newlyweds: job satisfaction, gender, and parental status as moderators.

Stress, on average, is bad for relationships. Yet stress at work is not always associated with negative relationship outcomes. The premise of the current study was that associations between workload and trajectories of marital satisfaction depend on circumstances that may constrain or facilitate partners' ability to negotiate their multiple roles. We hypothesized that the covariance between changes in workload and marital satisfaction over time should be moderated by (a) the extent to which spouses like their work, (b) their parental status, and (c) their gender. Analyses drawing upon eight waves of data on workload, work satisfaction, and marital satisfaction from 169 newlywed couples assessed over four years confirmed these predictions. Specifically, across couples, demands at work covaried positively with marital satisfaction for spouses who were more satisfied with their jobs. For nonparent couples, increases in husbands' workload covaried with increases in marital satisfaction for both spouses. For parent couples, however, increases in husbands' workload covaried with declines in marital satisfaction for both spouses. Unexpectedly, for parent couples, increases in wives' workload corresponded with increased marital satisfaction. Finally, consistent with predictions, wives were more affected by their husbands' workload than vice versa. Thus, tension between work and marriage is not inevitable, instead depending on circumstances that facilitate or impair performance in multiple roles. Couples, employers, and practitioners should recognize the role that external circumstances play in determining how work and marital life interact.

When forgiving enhances psychological well-being: the role of interpersonal commitment.

The present research addresses the question of when and why forgiving might enhance psychological well-being. The authors predict that forgiving is associated with enhanced well-being but that this association should be more pronounced in relationships of strong rather than weak commitment. This hypothesis received good support in Studies 1-3. Studies 2 and 3 addressed the issue of why forgiving might be associated with psychological well-being, revealing that this association was reduced after controlling for psychological tension (i.e., a psychological state of discomfort due to conflicting cognitions and feelings). Study 4 revealed that in the context of marital relationships, tendencies toward forgiving one's spouse exhibited a more pronounced association with psychological well-being than did tendencies to forgive others in general.
