Genetic and subjective sensitivity, relationship dynamics, and psychological distress in couples

Positive and negative aspects of intimate relationships influence mental health and well-being in couples. According to the environmental sensitivity framework, individuals differ in how strongly they are affected by their environment, with some individuals being more or less sensitive to both negative and positive experiences. The present study examined the longitudinal associations between positive and negative relationship dynamics, including marital satisfaction, positive bonding, and negative communication, and psychological distress as well as the extent to which individual differences in genetic and subjective measures of environmental sensitivity moderated the association between relationship dynamics and psychological distress in a sample of couples in the U.S. Army (n = 238 individuals representing 152 unique couples). Sensitivity was measured by self-report and a polygenic score derived from previous genome-wide association study results. Separate three-level multilevel models were conducted for each relationship dynamic and sensitivity variable. Only for subjective (i.e., self-reported) sensitivity did significant cross-level interactions emerge in predicting psychological distress, whereas no such interactions were found for genetic (i.e., polygenic score) sensitivity. Specifically, lower marital satisfaction and positive bonding were associated with higher psychological distress among subjectively highly sensitive individuals, and higher negative communication was associated with higher psychological distress among subjectively highly sensitive individuals. Findings suggest that both low positive and high negative relationship dynamics may have a greater effect on psychological distress among highly sensitive individuals, which may help to inform tailored intervention to meet the unique needs of couples.

Racial discrimination and parenting perceptions among low-income Black couples

Racism affects Black individuals in the United States through multiple institutional, social, and economic injustices. Relationship scientists have called for greater attention to the potentially harmful effects racism might exert on Black families. A small literature has begun to document negative associations between experiences of racism and romantic relationship functioning. However, even less empirical work has focused on a central relationship domain for many Black couples: parenting. The present study used cross-sectional data (N = 312 couples) from low-income Black couples who had recently had a child together. We examined associations between both partners' experiences of racial discrimination and their coparenting relationship quality and parenting stress. We next controlled for depression and relationship dedication as substantive covariates that could guide future research in this area. Actor-partner interdependence models revealed actor associations between discrimination and poorer parenting outcomes and a partner association specifically between one's partner's discrimination experience and own lower coparenting relationship quality. This partner effect was no longer significant, and actor effects were attenuated, when controlling for depression and relationship dedication, respectively. Our findings indicate that the negative effects of racial discrimination on Black couples' relationships are also apparent in the parenting domain, even above and beyond associations of individual depression and relationship dedication. These findings underscore the urgent need for more basic science to better understand the harms of racism for Black families, identify mechanisms that drive those effects, and highlight ways that clinical services can begin to address these impacts even now.

Relationship functioning moderates the link between history of childhood maltreatment and depression during pregnancy

Prenatal depression is a significant health issue associated with increased risk for poor mental and physical health outcomes among for both parents and their children. Having a history of childhood maltreatment is associated with increased risk for prenatal depression. Although research suggests that romantic relationship functioning likely plays a role in the links between childhood maltreatment and prenatal depression, it remains to be tested which aspects of relationship functioning modulate these associations. Using an actor-partner interdependence model framework (Kenny et al., 2006), the present study examined how specific aspects of romantic relationship functioning-relationship commitment, perceived partner support, constructive communication, and destructive conflict-moderated the links between mothers' and fathers' childhood maltreatment and depression during pregnancy. Participants included a subset of 1,135 low-income heterosexual couples (2,270 individuals) who enrolled in a randomized controlled trial of a relationship education program during pregnancy. Baseline, pretreatment data were used. Results indicated significant actor and partner effects of childhood maltreatment on prenatal depression. Further, these effects were moderated by specific indices of relationship functioning, such that the effect of one's own maltreatment on their prenatal depression was mitigated by high emotional support from partner and high constructive communication and was exacerbated by destructive conflict. Findings demonstrate that high relationship functioning can act as a protective factor, and low relationship functioning as a risk factor, in the link between one's own childhood maltreatment and their prenatal depression among both mothers and fathers.

Impact evaluation of the family expectations program and moderation by sociodemographic disadvantage

The federal government, through the Administration for Children and Families (ACF), has funded community-based relationship education programs for couples, individuals, and families, with a strong focus on serving economically disadvantaged and racially diverse families. This study evaluated the impact of a 36-hour, workshop-based couple relationship education program that was funded by ACF using a randomized controlled trial (RCT) design and intent-to-treat (ITT) analyses. Participants were 1320 couples who were either expecting a baby or had a baby within the past 3 months, at the time of enrollment. Follow-up surveys were administered 12 months later. Analyses evaluated program impacts on relationship stability, constructive communication, and destructive conflict compared to a no-treatment control group. Analyses showed a statistically significant impact of the program on destructive conflict (d = 0.10) but not on constructive communication (d = 0.06) or stability (d_Cox  = 0.10). Based on findings from previous evaluations, we also examined whether participants' levels of sociodemographic disadvantage moderated these effects. There was significant moderation by sociodemographic disadvantage on constructive communication and destructive conflict, but not on stability. Effects were observed for those at higher levels of sociodemographic disadvantage.

Impact of Prenatal Group Healthy Relationship Education on Postpartum Contraception

Objective

We aimed to evaluate the impact of an antenatal group healthy relationship education program on the postpartum use of long-acting reversible contraception (LARC).

Materials and Methods

This is a planned subgroup analysis of a larger randomized controlled trial. Pregnant and newly parenting women were randomized to either group healthy relationship education, "MotherWise," or no additional services. An evidence-based healthy relationship education program and individual case management sessions were provided. The program did not include any prenatal care or contraception counseling. This subgroup analysis included those participants with a nonanomalous gestation randomized at <40 weeks who received care and delivered at a single safety-net hospital and were discharged home with a live infant(s).

Results

From September 2, 2016 to December 21, 2018, 953 women were randomized in the larger trial; 507 met inclusion criteria for this study; 278 randomized to program and 229 controls. Participants were mostly young, parous, Hispanic, publicly insured women. Participants randomized to program were more likely to take a prescription medicine and be delivered through cesarean; there were not any other significant differences in baseline, antenatal, or perinatal outcomes. Those randomized to program were more likely to be discharged home with immediate postpartum LARC in place (odds ratio [OR] 1.87; confidence interval [CI] 1.17-3.00), and more likely to be using LARC at the postpartum visit (OR 2.19; CI 1.34-3.56).

Conclusion

Antenatal group healthy relationship education provided separately from prenatal care is associated with a twofold increase in the use of postpartum LARC.

Does income moderate basic relationship processes?

Objective

This study explores whether household income moderates the predictive association from adaptive processes (positive and negative interactions and commitment), enduring vulnerabilities (psychological distress), and stressors (financial strain) to future relationship satisfaction?

Background

Theory and research have long conceptualized socioeconomic status as a predictor of couple relations, but recent work questions whether socioeconomic status may moderate basic couple relationship processes.

Method

This study used data from a U.S. national sample of 927 adults aged 18-34 years in a cohabiting (marital or nonmarital) different-sex partnership (66% female; 22% non-White; 47% earned a high school diploma or GED as their highest education credential) surveyed five times at 4-to 6-month intervals. A series of latent curve models with structured residuals were used to examine between- and within-person associations.

Results

Robust between-persons associations emerged consistent with prior literature (e.g., those with more positive and less negative interactions, higher commitment, lower psychological distress, and less financial strain reported higher relationship satisfaction). One robust longitudinal association emerged at the within-person level: higher than typical negative interactions predicted intraindividual decreases in future relationship satisfaction. Within-person associations were more evident in the cross-section: at times when positive interactions and commitment were higher than one's own average and negative interactions and psychological distress were lower than average, relationship satisfaction was also higher than average. Income did not moderate any links with future relationship satisfaction.

Conclusion

Results suggest that basic longitudinal processes in relationships operate consistently across income level.

Overlap of relationship distress and intimate partner violence in community samples

Mixed-gender couples presenting for couple therapy are at 2-3 times higher risk for physical intimate partner violence (IPV) than community couples. However, it is unclear if this elevation of relative risk is the same in the general population because relationship distress and treatment-seeking are often confounded. We used archival data from three representative U.S. civilian samples and one representative U.S. Air Force sample to test the hypothesis that clinically significant relationship distress is associated with increased risk of various forms of IPV. In these community samples, those in mixed-gender distressed relationships were at 2-3 times higher risk than those in nondistressed relationships for any physical IPV during the past year and at 3-6 times higher risk for clinically significant psychological and physical IPV during the past year. Given that the increase in IPV risk is similar for individuals in distressed community relationships and therapy-seeking relationships, the prior findings of the elevated rates of IPV in clinical samples are unlikely to be due to therapy-seeking. Although epidemiological risk involves statistical, not causal, associations, the increased co-occurrence of IPV in distressed mixed-gender couples fits with numerous theories of IPV and has implications for both screening and future research.

Changes in couple, parenting, and individual functioning following Family Expectations program participation

The current study investigated changes in couple, parenting, and individual functioning following participation in Family Expectations, a relationship and parenting education program for new or expectant parents. The sample comprised 339 couples who participated in most sessions of the Family Expectations program and completed assessments at three different time points over a 12-month period. Study analyses examined: (a) change shortly following completion of the program, (b) associations between short-term change and subsequent change in outcomes at 12-month follow-up, and (c) differences in short-term change between married and unmarried couples. Significant improvements were observed in all three domains at short-term follow-up. Short-term changes, particularly for psychological distress, were predictive of long-term change in multiple domains. Few moderation effects by marital status were evident; those that appeared suggested stronger effects for married participants compared to unmarried. Study findings inform ongoing discussions into the utility of federally-funded relationship and parenting programming.

Longitudinal Associations Among Adolescents' Sexual Attitudes, Beliefs, and Behaviors

Youth sex and relationship education programs aim to improve adolescent well-being by changing their knowledge, beliefs, and attitudes regarding sex and their health. However, there is a gap in existing research linking these cognitive targets to relevant behaviors, and a particular dearth of data on links with sexual behaviors. The current study tested longitudinal links between cognitive factors related to sex (attitudes about sex, normative beliefs, risk-avoidant intentions, and confidence in refusal skills) and outcomes of sexual behaviors (recent sexual encounters, number of sexual partners, and frequency of condom use). Data were drawn from three waves of data from a panel study of US high-school students and were analyzed using cross-lagged structural equation modeling. We hypothesized direct, reciprocal links between intentions and behaviors, but this hypothesis was not supported. Instead, more conservative attitudes about sex emerged as the most consistent prospective predictor of fewer sexual encounters and sexual partners, though with small effect sizes (βs = - .08 to - .131, ps < .05). Further, bidirectional interrelationships were observed among several of the cognitive and behavioral variables over time. These results highlight attitudes about sex as a potentially useful intervention target, but also suggest that sex and relationship education curricula and evaluations should consider multiple pathways of links between cognition and behavior. Continued research is needed on causal links between adolescents' sexual attitudes, knowledge, intentions, and behavior.

Moderated mediation in relationship education: Communication, commitment, and sociodemographic disadvantage

This study tested moderated mediation-that is, whether the mechanisms of program impacts are different for different groups of people-in the Supporting Healthy Marriage (SHM) study of relationship education (RE) programs for low-income married couples. Large-scale evaluations of RE programs have yielded small effects in community settings. Understanding program mechanisms specific to disadvantaged populations may help improve program impacts. This study explored whether communication and commitment mediated program effects on relationship outcomes in the SHM study for participants with relatively higher or lower levels of sociodemographic disadvantage. The present study included all 6,298 couples who enrolled in the SHM study. Data on self-reported communication skills, commitment, happiness, warmth/support, conflict, and psychological abuse were used from wives' and husbands' 12-month follow-up assessments, and a risk index was constructed from nine baseline indicators of social, economic, and demographic disadvantage. Analyses used structural equation modeling to test (a) mediation by communication and commitment, and (b) moderation of the mediation paths by level of disadvantage. The programs improved all relationship outcomes measured. Communication mediated program impacts only for couples with moderate or low disadvantage. Commitment mediated program impacts for participants reporting lowest disadvantage only, with more evidence of mediation for wives than husbands. Further research is needed to determine mechanisms of RE among highly disadvantaged populations to improve services for those at highest risk of relationship distress and dissolution.

Relationship education for women during pregnancy: The impact of MotherWise on birth outcomes

The field of relationship science has called for more research on the impact of relationship education on child outcomes, yet studies in this area remain sparse, particularly regarding maternal and infant health at birth. Research on group prenatal care demonstrates that individual-oriented group interventions have a positive impact on infant birth outcomes, suggesting the need to consider the impacts of other forms of group programming for women. The current study examined the impact of MotherWise, an individual-oriented relationship education and brief case management/coaching program for minority and low-income pregnant women, on birth outcomes. The study sample included 136 women who enrolled in a larger randomized controlled trial of MotherWise during early pregnancy. Although statistical power was limited due to the sample size and the effects were not outright significant at p < 0.05, results indicated that the effects of MotherWise on birth outcomes were small to moderate in size (0.23 for birthweight, 0.46 for preterm birth) and suggest important avenues for future tests of relationship education programs and their impacts on maternal and infant health. The current study suggests that relationship education during pregnancy could directly impact women's and infant's health.

Online relationship education for help-seeking low-income couples: A Bayesian replication and extension of the OurRelationship and ePREP programs

Low-income couples are at increased risk for relationship instability and divorce. In response, online relationship education programs such as ePREP and OurRelationship have been developed to more easily reach this population. A previous trial indicated that these programs promote relationship functioning (Doss et al., 2020) and individual well-being (Roddy et al., 2020a). However, given that these effects were notably larger than previous studies of in-person relationship education and approached effect sizes observed in couple therapy, it is possible that the magnitude of these effects was somewhat spurious; therefore, these findings need replication. The current manuscript seeks to replicate these programs' previous effects on relationship functioning and determine whether these effects are stable. Using a sample of 671 low-income couples seeking relationship help (N = 1337 individuals) and Bayesian estimation, the current study replicated previous findings that the OurRelationship and ePREP programs offered with four coaching calls produced reliable improvements in relationship functioning relative to a 6-month waitlist control group. There were no statistically reliable differences between the two active interventions. Bayesian analyses indicated that the effects of the two online programs were larger than the average effects of in-person relationship education for low-income couples reported in previous studies, roughly equivalent to efficacy studies of in-person relationship education reported in previous studies, smaller than those that resulted from the OurRelationship program delivered to distressed couples without an income requirement and smaller than couple therapy.

Introduction to special section: Federally funded, community-based healthy marriage and responsible fatherhood program impact studies

The focus of this special section is impact studies that were conducted as part of the Administration for Children and Families' Healthy Marriage and Responsible Fatherhood initiative. This initiative has led to more than 2 million people receiving relationship education and fatherhood programs across the United States over the last two decades. Community organizations develop these programs, select their curricula and content, and run these programs in their local communities. Many programs funded in the 2015-2020 cohort of grantees included randomized controlled trials of program effectiveness; some of these studies are presented in this issue, with the goal of marrying the field of program evaluation and family science.

Happy, healthy, and wedded? How the transition to marriage affects mental and physical health

Decades of research have documented the apparent health benefits of marriage, but the dynamics of how health may change across the transition to marriage are not fully understood. In two studies, we compared being unmarried or married on several indices of mental and physical health. In Study 1, we used a national sample of 1,078 individuals in different-sex relationships who completed surveys by mail. Compared with those who were cohabiting or dating, married individuals generally reported better mental and physical health than those in less committed relationships, and most differences remained when controlling for putative selection factors. Study 2 used longitudinal data from the participants in the Study 1 sample who later married (N = 168) to study changes within individuals over the transition to marriage on the same indicators. Six waves of mailed surveys spanning 20 months were employed. Findings of Study 2 indicated that although some indicators of mental and physical health were improving up until the point of marriage, these indicators then stabilized or began to decline, with women experiencing these declines more than men. Findings are more consistent with selection effects (i.e., better-adjusted individuals are more likely to get married) than social causation effects (i.e., marriage causes improvements in mental and physical health) and suggest that if marriage does have a causal effect on well-being in the short term, it may actually manifest in the lead-up to the wedding. Implications of these findings are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

A Latent Class Analysis of Predictors for Engaging in Sex: A Study with Ethnically Diverse High School Students

Sexual activity occurs among a large portion of young adults and adolescents, including high school students. While about 40% of high school students nationwide have engaged in sexual intercourse, more information is needed about how individual characteristics may relate to larger patterns of adolescent sexual behavior. This exploratory study utilized a latent class analysis (LCA) to identify clusters of high school students (N = 801) based on demographic characteristics, sexual refusal skills, healthy relationship skills, sociosexuality, internalizing symptoms, alcohol use, various forms of social support (i.e., parents, friends, teachers), and sexual activity at baseline to predict their sexual behavior at a 6-month follow-up. Four unique latent classes were identified based on these baseline predictors. Distinctions in the profiles of high schoolers varied significantly by internalizing symptoms, race/ethnicity, sexually conservative attitudes, and social support in the prediction of adolescent sexual activity at 6-months. This study contributes to the investigation of demographic, social, psychological, attitudinal, and behavioral factors that may distinguish high school students from one another in terms of their longitudinal rates of sexual activity.

Parent-Child Relationship Quality in the Family of Origin and Later Romantic Relationship Functioning: A Systematic Review

A large and diverse literature has shown that parent-child relationship quality shapes development to affect later romantic relationship functioning. Guided by the developmental psychopathology framework, the current systematic review aimed to characterize the links between two major subtypes of parent-child relationship quality (parent-child attachment security and interaction quality) and several romantic relationship outcomes (i.e., adjustment, attachment security, aggression, and observed interaction quality), as well as to identify mechanisms accounting for these associations. We focused on studies that included both members of a couple/partnership for dyadic assessment of romantic relationship functioning, to more accurately and fully capture both partners' perspectives. A total of 40 articles met inclusion criteria, most of which sampled early/emerging adult couples between the ages of 18 and 26 years. Findings suggest that parent-child attachment security and interaction quality have similar associations with dyadic romantic relationship functioning, with the strongest evidence of effects on romantic relationship adjustment and observed interactions between romantic partners. Many studies found gender differences in effects, as well as cascading effects across development and over the course of a relationship. We argue that it is important for future studies to explore effects of one partner's parent-child relationship quality history on the other partner's romantic relationship adjustment and behavior, and to evaluate the extent to which parent-child attachment security mediates associations between parent-child interaction quality and romantic relationship functioning.

The Co-Occurrence of Child Maltreatment and Intimate Partner Violence in Families: Effects on Children's Externalizing Behavior Problems

Children exposed to maltreatment are at risk of experiencing intimate partner violence (IPV) and behavioral problems. This study examined different forms of family violence that co-occur and their relationship to children's externalizing behaviors across developmental stages (early childhood, middle childhood, adolescence). Longitudinal data (N = 1,987) at baseline and 18 months and 36 months post-baseline from the NSCAW II were used. Mixture modeling was employed in which latent class models estimated subgroups of children who experienced co-occurring forms of family violence; regression models estimated which subgroups of children were at risk of externalizing behaviors. Three latent classes were identified across developmental stages: high family violence, low family violence, and child physical abuse and psychological aggression. For children in early childhood, a fourth class was identified: partner and child physical abuse and child psychological aggression. Results from regression models revealed differences in externalizing scores by class membership across developmental age groups and over time. That distinct classes of child maltreatment and IPV co-occur and differentially impact children's behavior suggests a need for strong prevention and intervention responses to address children's dual maltreatment and IPV exposure.

A Closer Examination of Relational Outcomes from a Pilot Study of Abbreviated, Intensive, Multi-Couple Group Cognitive-Behavioral Conjoint Therapy for PTSD with Military Dyads

Cognitive-behavioral conjoint therapy for posttraumatic stress disorder (CBCT for PTSD) is associated with improvements in patients' PTSD symptoms, partners' psychological distress, and relationship satisfaction. However, little is known about whether CBCT for PTSD is associated with changes in other relationship domains that have theoretical and clinical relevance to the relational context of PTSD. The current study is a secondary analysis of relational outcomes from an uncontrolled, within-group trial designed to examine whether an abbreviated, intensive, multi-couple group version of CBCT for PTSD (AIM-CBCT for PTSD) delivered in a retreat during a single weekend was associated with improvements in PTSD symptoms and relationship satisfaction. In this investigation, we examined whether AIM-CBCT for PTSD is also associated with improvements in ineffective arguing, supportive dyadic coping by partner, joint dyadic coping, and partners' accommodation of patients' PTSD symptoms. Participants were 24 couples who included a post-9/11 U.S. service member or veteran with PTSD. At 1- and 3-month follow-up, patients reported significant reductions in couples' ineffective arguing (ds = -.71 and -.78, respectively) and increases in supportive dyadic coping by partners relative to baseline (ds = .50 and .44, respectively). By 3-month follow-up, patients also reported significant increases in couples' joint dyadic coping (d = .57), and partners reported significant reductions in their accommodation of patients' PTSD symptoms (d = -.44). Findings suggest that AIM-CBCT for PTSD is associated with improvements in multiple relationship domains beyond relationship satisfaction but that these may be differentially salient for patients and partners.

Effects of ePREP and OurRelationship on Low-Income Couples' Mental Health and Health Behaviors: a Randomized Controlled Trial

Relationship distress is a pervasive problem in the USA that disproportionally impacts couples with low-income levels. The goal of the present study was to evaluate the effectiveness of two online relationship interventions, OurRelationship and ePREP, both of which were supported by a paraprofessional coach, in improving mental health and physical health behaviors with low-income couples. Couples (N = 742) were randomized to either intervention or a 6-month waitlist control group and assessed pre-, mid-, and post-intervention as well at 4 and 6 months after randomization. Results from multilevel models indicated that during treatment, compared to couples in the waitlist group, couples in the intervention groups reported significantly greater improvements in mental health that were small to moderate in magnitude (psychological distress, anger, problematic alcohol use, and perceived stress) as well as improvements in physical health/health behaviors (perceived health, insomnia, and exercise) that were small in magnitude. Furthermore, the differences between intervention and waitlist groups were maintained over follow-up. Treatment gains in both mental health and physical health behaviors were generally stronger for those who began treatment with greater difficulties in those areas. Implications of these findings with regard to intervention and policy are discussed.

Having a Baby: Impact on Married and Cohabiting Parents' Relationships

The current study evaluates the effects of having a baby on relationship quality and stability, contrasting married and unmarried cohabiting parents (N = 179; 38% unmarried cohabiting). Participants provided several waves of data, including time points before, during, and after pregnancy. Results indicated that cohabiting parents broke up at a significantly higher rate after having a baby compared to married parents. In terms of relationship quality, interrupted time-series analyses indicated that negative communication significantly increased after baby regardless of marital status. In addition, married parents had significantly higher levels of relationship satisfaction and commitment before baby compared to cohabiting parents but experienced modest declines in relationship satisfaction after baby. Cohabiting parents did not show such declines but remained lower in satisfaction throughout the study. Gender moderated commitment trajectories, such that married and cohabiting women demonstrated decreased commitment after baby, but married and cohabiting men demonstrated no significant changes in commitment. This study adds to the literature by examining both relationship stability and relationship quality trajectories from before pregnancy to after the birth of a baby among married and cohabiting parents in the same sample. Implications of these findings for practice and future research are discussed.

Within-Couple Associations Between Communication and Relationship Satisfaction Over Time

Relationship science contends that the quality of couples’ communication predicts relationship satisfaction over time. Most studies testing these links have examined between-person associations, yet couple dynamics are also theorized at the within-person level: For a given couple, worsened communication is presumed to predict deteriorations in future relationship satisfaction. We examined within-couple associations between satisfaction and communication in three longitudinal studies. Across studies, there were some lagged within-person links between deviations in negative communication to future changes in satisfaction (and vice versa). But the most robust finding was for concurrent within-person associations between negative communication and satisfaction: At times when couples experienced less negative communication than usual, they were also more satisfied with their relationship than was typical. Positive communication was rarely associated with relationship satisfaction at the within-person level. These findings indicate that within-person changes in negative communication primarily covary with, rather than predict, relationship satisfaction.

Online programs improve relationship functioning for distressed low-income couples: Results from a nationwide randomized controlled trial

OBJECTIVE

Although low-income couples experience greater relationship challenges, they have limited access to effective relationship interventions. Furthermore, most previous efforts to improve low-income couples' relationships have yielded very small effects (Hawkins & Erickson, 2015). In an effort to overcome these limitations, this study investigated the effectiveness of 2 web-based interventions for low-income couples.

METHOD

In total, 742 low-income couples (N = 1,484 individuals; mean [M] age = 33; 55% White, non-Hispanic; 52% married; median [Mdn] annual household income = $27,000) were recruited nationally and randomized to the OurRelationship program, the ePREP program, or a waitlist control group. Couples were repeatedly assessed for 6 months using self-report measures of relationship satisfaction, communication conflict, intimate partner violence, emotional support, and breakup potential. Relationship status was assessed at 6-month follow-up.

RESULTS

Compared to the control group, intervention couples experienced significantly greater improvements in all 5 domains of relationship functioning (Mdn |d| = 0.46) by the end of the program; these effects were maintained in the 4 months after treatment. However, neither program significantly reduced the frequency of breakups by the 6-month follow-up. Differences between couples in the two interventions were minimal (Mdn Cohen's |d| = 0.11); however, couples in the OurRelationship program experienced significantly greater decreases in conflict (d = 0.24).

CONCLUSIONS

The results indicate that brief, web-based interventions can serve a central role in delivering effective services to low-income couples. Additionally, the general equivalence of the two interventions indicates that both communication-focused and problem-focused interventions can be successful in improving the relationship functioning of low-income couples.

Intensive, Multi-Couple Group Therapy for PTSD: A Nonrandomized Pilot Study With Military and Veteran Dyads

Cognitive-behavioral conjoint therapy for posttraumatic stress disorder (CBCT for PTSD; Monson & Fredman, 2012) is efficacious in improving PTSD symptoms and relationship adjustment among couples with PTSD. However, there is a need for more efficient delivery formats to maximize engagement and retention and to achieve faster outcomes in multiple domains. This nonrandomized trial was designed to pilot an abbreviated, intensive, multi-couple group version of CBCT for PTSD (AIM-CBCT for PTSD) delivered over a single weekend for 24 couples that included an active-duty service member or veteran with PTSD who had deployed in support of combat operations following September 11, 2001. All couples completed treatment. Assessments conducted by clinical evaluators 1 and 3 months after the intervention revealed significant reductions in clinician-rated PTSD symptoms (ds = -0.77 and -0.98, respectively) and in patients' self-reported symptoms of PTSD (ds = -0.73 and -1.17, respectively), depression (ds = -0.60 and -0.75, respectively), anxiety (ds = -0.63 and -0.73, respectively), and anger (ds = -0.45 and -0.60, respectively), relative to baseline. By 3-month follow-up, partners reported significant reductions in patients' PTSD symptoms (d = -0.56), as well as significant improvements in their own depressive symptoms (d = -0.47), anxiety (d = -0.60), and relationship satisfaction (d = 0.53), relative to baseline. Delivering CBCT for PTSD through an abbreviated, intensive multi-couple group format may be an efficient strategy for improving patient, partner, and relational well-being in military and veteran couples with PTSD.

Political Party Identification and Romantic Relationship Quality

Although there are studies on voting similarity in mate selection, very little research has examined party identification and relationship quality. We assessed associations between reports of personal and partner voting behavior (Democrat, Republican, or Independent) and both relationship adjustment and commitment to one's partner. We used a national (U.S.) sample of individuals (N = 510) in their 20s and 30s who were mostly in different-sex, serious relationships (Mdn duration = 5.25 years; 50% married). Controlling for age, college graduation, income, religiosity, minority status, and duration of relationship, voting Republican was associated with higher levels of commitment compared to voting Democrat. Similarly, being partnered with someone voting Republican was associated with higher relationship adjustment and commitment compared to being partnered with someone voting Democrat. Notably, differences in commitment were found only among those who were not already married or engaged. Findings were largely consistent with numerous online reports of survey data that have shown modestly greater relationship quality among those who report being politically conservative. While research has shown that people are less attracted to those who vote differently and that voting differently can be associated with lower relationship quality, we did not generally find perceived voting similarity to be associated with relationship adjustment or commitment. There was one exception: In exploratory analyses, Republicans paired with Democrats tended to report substantially lower relationship adjustment than if paired with Republicans. Implications for political differences among intimate partners and clinical work around these themes are discussed.

"Will you complete this survey too?" Differences between individual versus dyadic samples in relationship research

This study examines the ways in which collecting data from individuals versus couples affects the characteristics of the resulting sample in basic research studies of romantic relationships. From a nationally representative sample of 1,294 individuals in a serious romantic relationship, approximately half of whom were randomly selected to invite their partner to participate in the study, we compare relationship, individual, and demographic characteristics among 3 groups: individuals randomized to invite their partner and whose partner participated in the study, individuals randomized to invite their partner but whose partner did not participate, and individuals who were not randomized to invite their partner. Results indicated that individuals whose partner participated reported the highest levels of relationship and individual well-being relative to comparison groups, as well as individuals who participated alone despite being asked to invite their partner, reported the lowest levels of relationship and individual well-being relative to comparison groups. Effect size magnitudes indicated the strongest group differences with respect to relationship variables, particularly cognitive appraisals of overall relationship stability and satisfaction. Implications for romantic relationship research and study design are discussed. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Trajectories of relationship confidence in intimate partnerships

The current study examined trajectories of relationship confidence, defined as the belief that oneself and the partner together have the skills needed to navigate conflict and maintain a partnership into the future. This study uses data from a sample of 1,294 partnered but unmarried young adults to examine trajectories of relationship confidence across 11 waves of assessment over more than 4 years and the between- and within-person predictors of those trajectories. On average, relationship confidence was high at the outset of the study and remained stable over time. Underlying the overall stability, however, men's and women's trajectories flowed in opposite directions. Women started with more confidence than men, and their confidence decreased over time while men's increased, although the analysis of individuals rather than couples must be considered when interpreting this finding. Individuals in longer partnerships, who were cohabiting at Wave 1, with lower levels of avoidant attachment, more frequent positive interactions and higher satisfaction at Wave 1, and those who married during the study, had higher initial relationship confidence. Having children with a prior partner predicted lower initial confidence and faster decreases over time only for women. At the within-person level, relationship confidence was higher than usual at waves when more positive interactions, less negative interactions, and higher relationship satisfaction were reported, particularly for women. Results highlight the substantial variability in trajectories of relationship confidence among individuals in unmarried relationships as well as an array of factors that influence its development.

Treatment-as-Usual for Couples: Trajectories Before and After Beginning Couple Therapy

Couple therapy has been shown to be a meaningful way to improve couples' relationships. However, less information is known about couples' functioning prior to entering treatment in community settings, as well as how their relationship functioning changes from initiating therapy onward. This study examined 87 couples who began community-based couple therapy during a longitudinal study of couples in the military. The couples were assessed six times over the course of 3 years, including time points before and after starting couple therapy. Using an interrupted-time series design, we examined trajectories across the start of couple therapy in relationship satisfaction, divorce proneness, and negative communication. The results demonstrated that couples' relationship satisfaction was declining and both divorce proneness and negative communication were increasing prior to entering couple therapy. After starting couple therapy, couples' functioning on all three variables leveled off but did not show further change, but previous experience in relationship education moderated these effects. Specifically, those who were assigned to the relationship education program (vs. control) demonstrated greater reductions in divorce proneness and greater increases marital satisfaction after starting therapy; however, they also started more distressed.

Unequally into "Us": Characteristics of Individuals in Asymmetrically Committed Relationships

This study examined characteristics of individuals that are associated with being in asymmetrically committed relationships (ACRs), defined as romantic relationships in which there was a substantial difference in the commitment levels of the partners. These ACRs were studied in a national sample of unmarried, opposite-sex romantic relationships (N = 315 couples). Perceiving oneself as having more potential alternative partners was associated with increased odds of being the less committed partner in an ACR compared to not being in an ACR, as was being more attachment avoidant, having more prior relationship partners, and having a history of extradyadic sex during the present relationship. Additionally, having parents who never married was associated with being the less committed partner in an ACR but parental divorce was not. Although fewer characteristics were associated with being the more committed partner within an ACR, more attachment anxiety was associated with increased odds of being in such a position compared to not being in an ACR. We also address how some findings change when controlling for commitment levels. Overall, the findings advance understanding of commitment in romantic relationships, particularly when there are substantial asymmetries involved. Implications for both research on asymmetrical commitment as well as practice (e.g., therapy or relationship education) are discussed.

Associations of Army Fathers' PTSD Symptoms and Child Functioning: Within- and Between-Family Effects

This study examined the within-family and between-family associations between fathers' military-related PTSD symptoms and parent ratings of children's behavioral and emotional problems. The sample included married couples (N = 419) with children composed of a civilian wife and an active-duty husband serving in the U.S. Army. Results indicate that changes in fathers' PTSD symptoms over time were associated with corresponding changes in both mothers' and fathers' reports of child behavioral and emotional problems. These within-family findings were independent from between-family effects, which showed that higher average PTSD symptomatology was associated with more overall behavioral and emotional problems for children. This study uses advances in statistical methodologies to increase knowledge about how PTSD symptoms and child problems are related, both across different families and over time within families.

Sexuality Within Female Same-Gender Couples: Definitions of Sex, Sexual Frequency Norms, and Factors Associated with Sexual Satisfaction

Despite a growing number of female same-gender (FSG) relationships, couples-based research and interventions have focused primarily on mixed-gender couples. Consequently, research has applied a heteronormative lens to understanding some relationship factors, including sexuality. The current study sought to provide descriptive data regarding frequency and conceptualizations of sex across partners in FSG relationships, as well as to analyze how relationship factors are associated with sexual satisfaction in this population. Participants (N = 206) were 103 adult FSG couples who had been together for at least 2 months. Individuals provided self-report data on how they conceptualized sex, and actor-partner models were utilized to assess relationship factors associated with sexual satisfaction. Findings indicated that women in FSG relationships hold broad definitions of sex, with the majority of behaviors conceptualized as sex, including acts that involved partnered genital touching. In dyadic actor-partner models, sexual satisfaction was predicted by several factors including sexual frequency, emotional intimacy, and sexual intimacy. Unexpectedly, higher desired sexual frequency was associated with lower sexual satisfaction; however, this finding only emerged after controlling for actual sexual frequency, suggesting that discrepancies between desired and actual sex frequency may be important for FSG couples. Implications for clinical practice with FSG couples are explored, including a strength-based focus on broad conceptualizations of sex within this population and targeting relationship factors associated with sexual satisfaction.

Introduction to the special issue: Advances in methods and measurement in family psychology

This special issue presents a collection of reports that highlight recent advances in methods and measurement and also shed light on the complexity of family psychology. The importance of theory in guiding solid family science is evident throughout these reports. The reports include guides for researchers who incorporate direct observation into their research protocols and the ever-expanding field of tele-health interventions. Advanced analytic approaches are offered in the areas of grid sequence analysis, latent fixed-effects models, and the Factors of Curves Model (FOCUS). These sophisticated analytic approaches may be applied to advance systemic thinking in family psychology. The last set of articles illustrate how complex and innovative methodologies are applied to address important societal issues. Work experiences and marital relationships in African American couples address the importance of spillover effects in contemporary families. The creation of biobehavioral plasticity index has the potential to inform gene x environment contributions to family functioning. Finally, the unique methodological issues that are particularly germane to the diverse nature of stepfamilies and nonresident fathers are addressed. We hope that readers of this special issue will return to these reports as resources and examples of theory-driven methods and measurements. (PsycINFO Database Record

Once a Cheater, Always a Cheater? Serial Infidelity Across Subsequent Relationships

Although there is a large body of research addressing predictors of relationship infidelity, no study to our knowledge has specifically addressed infidelity in a previous relationship as a risk factor for infidelity in a subsequent relationship. The current study addressed risk for serial infidelity by following adult participants (N = 484) longitudinally through two mixed-gender romantic relationships. Participants reported their own extra-dyadic sexual involvement (ESI) (i.e., having sexual relations with someone other than their partner) as well as both known and suspected ESI on the part of their partners in each romantic relationship. Findings from logistic regressions showed that those who reported engaging in ESI in the first relationship were three times more likely to report engaging in ESI in their next relationship compared to those who did not report engaging in ESI in the first relationship. Similarly, compared to those who reported that their first-relationship partners did not engage in ESI, those who knew that their partners in the first relationships had engaged in ESI were twice as likely to report the same behavior from their next relationship partners. Those who suspected their first-relationship partners of ESI were four times more likely to report suspicion of partner ESI again in their next relationships. These findings controlled for demographic risk factors for infidelity and held regardless of respondent gender or marital status. Thus, prior infidelity emerged as an important risk factor for infidelity in next relationships. Implications for novel intervention targets for prevention of serial relationship infidelity are discussed.

Associations Between Participant Ratings of PREP for Strong Bonds and Marital Outcomes 1 Year Postintervention

After completing a relationship education program, collecting participant evaluations of the program is common practice. These are generally used as an index of "consumer satisfaction" with the program, with implications for feasibility and quality. Rarely have these ratings been used as predictors of changes in marital quality, although such feedback may be the only data providers collect or have immediate access to when considering the success of their efforts. To better understand the utility of such ratings to predict outcomes, we evaluated links between participant ratings and changes in self-reported marital satisfaction and communication scores one year later for a sample of 191 Army couples who had participated in a relationship education program delivered by Army chaplains (PREP for Strong Bonds). Overall ratings of general satisfaction with the program and the leader did not predict changes in marital outcomes one year later, whereas higher ratings of how much was learned, program helpfulness, increased similarity in outlook regarding Army life, and helpfulness of communication skills training predicted greater change in communication skills one year later. Higher ratings of items reflecting intent to invest more time in the relationship, and increased confidence in constructive communication and working as a team with the spouse predicted greater increases in both marital satisfaction and communication skills one year later. The constructs of intention and confidence (akin to perceived behavioral control) suggest that the Theory of Planned Behavior may be particularly useful when considering which Army couples will show ongoing benefit after relationship education.

Within- and Between-Family Associations of Marital Functioning and Child Well-being

This study clarifies within-family and between-family links between marital functioning and child wellbeing. Expanding on existing prospective research, this study tests whether changes in parents' marital functioning are associated with corresponding changes in their children's wellbeing, independent from associations that exist when comparing different families. Participants (N = 1033) were members of married, opposite-sex couples with children who participated in five waves of a larger study of marriage in the U.S. Army. Spouses' constructive communication, verbal conflict, and marital satisfaction each showed between-family associations with parent-reported child internalizing and externalizing problems. In contrast, within-family associations were significant only for parents' communication behaviors. That is, parents who reported lower levels of marital satisfaction also reported lower child wellbeing, whereas change in parents' communication was associated with change in child wellbeing over time. Isolating within-family effects is important for understanding marital and child functioning and for identifying potential targets for effective intervention.

Changes in the Sexual Relationship and Relationship Adjustment Precede Extradyadic Sexual Involvement

Extradyadic sexual involvement (ESI) is associated with negative consequences for individuals and threatens couple stability. Research on ESI in unmarried samples has been marked by methodological limitations, such as examining only mean levels of sexual satisfaction or frequency to predict later ESI as opposed to changes in various aspects of the sexual relationship over time. The current study compared linear trajectories of four aspects of the sexual relationship-sexual satisfaction, frequency of sex, comfort communicating about sex, and sexual closeness-between individuals in opposite-sex, unmarried relationships who subsequently engaged in ESI (ESI group; n = 183) compared to individuals who did not engage in ESI (non-ESI group; n = 603). Trajectories of relationship adjustment were also evaluated leading up to ESI as well as controlled for in models evaluating the sexual relationship. Results indicated that relationship adjustment declined for individuals preceding ESI, but did not change for the non-ESI group. When controlling for relationship adjustment, comfort communicating about sex decreased for ESI women but increased for ESI men. Some results became nonsignificant after controlling for relationship adjustment, including that sexual satisfaction declined more steeply in the ESI group compared to the non-ESI group, and ESI women significantly decreased in sexual closeness while ESI men demonstrated no significant change. Some mean level differences were also discovered directly before ESI. Conclusions include that changes in a couple's sexual relationship and relationship adjustment are associated with ESI behaviors, providing novel information regarding normative and risk trajectories.

The Effectiveness of the Within Our Reach Relationship Education Program for Couples: Findings from a Federal Randomized Trial

This study examined the effectiveness of a couple-based relationship education program, Within Our Reach. Secondary data (n = 3,609) were analyzed from the federal Supporting Healthy Marriage project. Couples were randomly assigned to receive Within Our Reach and associated services or to a no-treatment (treatment-as-usual) control group. Those assigned to Within Our Reach reported better couple and individual outcomes on 8 of 12 outcomes measured (M ES = .15) at the 12-month follow-up and 6 of 10 outcomes measured at the 30-month follow-up (M ES = .14), including higher relationship happiness, more warmth and support, more positive communication, less negative behavior and emotion, less psychological abuse, less physical assault (for men), lower psychological distress (for women), and less infidelity. They were also less likely to report that their marriage was in trouble. These effects were generally small in size and many were replicated across the two follow-ups. There were no significant differences between those assigned to Within Our Reach versus control on cooperative parenting, severe psychological assault, or percent married. Implications for future research, programming, and policy are discussed.

Can marriage education mitigate the risks associated with premarital cohabitation?

This study tested whether relationship education (i.e., the Prevention and Relationship Education Program; PREP) can mitigate the risk of having cohabited before making a mutual commitment to marry (i.e., "precommitment cohabitation") for marital distress and divorce. Using data from a study of PREP for married couples in the U.S. Army (N = 662 couples), we found that there was a significant association between precommitment cohabitation and lower marital satisfaction and dedication before random assignment to intervention. After intervention, this precommitment cohabitation effect was only apparent in the control group. Specifically, significant interactions between intervention condition and cohabitation history indicated that for the control group, but not the PREP group, precommitment cohabitation was associated with lower dedication as well as declines in marital satisfaction and increases in negative communication over time. Furthermore, those with precommitment cohabitation were more likely to divorce by the 2-year follow-up only in the control group; there were no differences in divorce based on premarital cohabitation history in the PREP group. These findings are discussed in light of current research on cohabitation and relationship education; potential implications are also considered.

Positive Interactions and Avoidant and Anxious Representations in Relationships with Parents, Friends, and Romantic Partners

We examined associations between positive interactions and avoidant and anxious representations in relationships with parents, friends, and romantic partners. Two hundred adolescents completed questionnaires, observations, and attachment interviews. From a between-person perspective, those adolescents with more positive interactions overall had less avoidant representations. Within persons, more positive interactions were relative to one's own average level in relationships, the less avoidant representations were for that type of relationship. Adolescents were less anxious about a particular type of relationship if they have positive interactions in their other types of relationships. Finally, representations were primarily predicted by interactions in the same type of relationship; interactions in other relationships contributed little. The findings underscore the importance of examining representations of particular types of relationships.

A Randomized Controlled Trial of Relationship Education in the U.S. Army: 2-Year Outcomes

This study examined the effectiveness of an evidence-based, community-delivered adaptation of couple relationship education (CRE; specifically, PREP, The Prevention and Relationship Enhancement Program) delivered at two Army installations. The study is a randomized controlled trial with two years of follow-up, examining marital quality and stability. Sample composition was 662 married couples with a spouse in the U.S. Army. Analyses yielded no evidence of overall enduring intervention effects on relationship quality but couples assigned to intervention at the higher risk site were significantly less likely than controls to be divorced at the two-year follow-up (8.1% vs. 14.9%, p < .01). This effect was moderated by ethnic minority status. Specifically, the impact of the intervention on divorce was strongest for minority couples. The findings add to the literature on who may benefit most from CRE.

Perceived criticism and marital adjustment predict depressive symptoms in a community sample

Depressive symptoms are related to a host of negative individual and family outcomes; therefore, it is important to establish risk factors for depressive symptoms to design prevention efforts. Following studies in the marital and psychiatric literatures regarding marital factors associated with depression, we tested two potential predictors of depressive symptoms: marital adjustment and perceived spousal criticism. We assessed 249 spouses from 132 married couples from the community during their first year of marriage and at three time points over the next 10 years. Initial marital adjustment significantly predicted depressive symptoms for husbands and wives at all follow-ups. Further, perceived criticism significantly predicted depressive symptoms at the 5- and 10-year follow-ups. However, at the 1-year follow-up, this association was significant for men but not for women. Finally, a model where the contributions of marital adjustment and perceived criticism were tested together suggested that both play independent roles in predicting future depressive symptoms. These findings highlight the potential importance of increasing marital adjustment and reducing perceived criticism at the outset of marriage as a way to reduce depressive symptoms during the course of marriage.

Commitment across the Transition to Parenthood among Married and Cohabiting Couples

Commitment has long been hypothesized to increase across the transition to parenthood, even though much research has found that relationship functioning declines during this period. We examined change in interpersonal commitment, measured as personal dedication and relationship confidence, and constraint commitment, measured as felt constraint, across the transition to parenthood. We tested for marital status differences in the change in commitment across the transition among three groups: cohabitation, marriage preceded by cohabitation, and direct marriage. Data came from the New Parents Project, a community sample of 173 married and cohabiting couples. Difference-in-difference estimates indicated that cohabiting fathers, in comparison to married fathers, dropped further in personal dedication and relationship confidence and increased more in felt constraint across the transition to parenthood. No significant differences across the transition were found between cohabiting and married mothers. Further research on the transition to parenthood among unmarried couples is suggested.

Fluctuation in Relationship Quality Over Time and Individual Well-Being: Main, Mediated, and Moderated Effects

This study examined how the degree of within-person variation (or temporal fluctuation) in relationship quality over time was associated with well-being (psychological distress and life satisfaction). A national sample of 18- to 34-year-old men and women in unmarried, opposite-sex relationships completed six waves of surveys every 4 months (N = 748). Controlling for initial levels of and linear changes in relationship quality, greater temporal fluctuation in relationship quality over time was associated with increasing psychological distress and decreasing life satisfaction over time. Decreased confidence in one's relationship partially mediated these associations. Moderation analyses revealed that the association between fluctuations in relationship quality and change in life satisfaction was stronger for women, participants cohabiting with their partners, and those with greater anxious attachment, whereas the association between fluctuations in relationship quality and change in psychological distress was stronger for people with greater avoidant attachment.

Relationship quality, commitment, and stability in long-distance relationships

Using a nationally representative sample (N = 870), the present study compared long-distance romantic relationships to close-proximity romantic relationships in terms of relationship quality, commitment, and stability. Individuals in long-distance relationships generally reported higher levels of relationship quality on a number of relationship quality variables, as well as higher levels of dedication to their relationships and lower levels of feeling trapped (i.e., felt constraint), but were similar to individuals in close-proximity relationships in terms of perceived and material constraints. Although individuals in long-distance relationships perceived a lower likelihood of breaking up with their partner at the initial time point, they were as likely as the individuals in close-proximity relationships to have broken up by the follow-up assessment.

Sliding versus Deciding in Relationships: Associations with Relationship Quality, Commitment, and Infidelity

From choosing a partner to date to deciding to cohabit or marry, individuals are faced with many relationship choices. Given the costs of failed relationships (e.g., personal distress, problems with work, lower well-being for children, lost opportunities to meet other partners), it is important consider how individuals are approaching these decisions. The current study tested if more thoughtful and clear relationship decision-making processes would relate to individuals' levels of satisfaction with and dedication to their partners as well as their extra-dyadic involvements. In a sample of 252 men and women, the results showed that regardless of relationship status (i.e., dating, cohabiting, or married), those who reported more thoughtful decision-making processes also reported more dedication to their partners, higher satisfaction with the relationship, and fewer extra-dyadic involvements.

A randomized clinical trial of the effectiveness of premarital intervention: moderators of divorce outcomes

This study examined the effects of premarital relationship intervention on divorce during the first 8 years of first marriage. Religious organizations were randomly assigned to have couples marrying through them complete the Prevention and Relationship Education Program (PREP) or their naturally occurring premarital services. Results indicated no differences in overall divorce rates between naturally occurring services (n = 44), PREP delivered by clergy at religious organizations (n = 66), or PREP delivered by professionals at a university (n = 83). Three moderators were also tested. Measured premaritally and before intervention, the level of negativity of couples' interactions moderated effects. Specifically, couples observed to have higher levels of negative communication in a video task were more likely to divorce if they received PREP than if they received naturally occurring services; couples with lower levels of premarital negative communication were more likely to remain married if they received PREP. A history of physical aggression in the current relationship before marriage and before intervention showed a similar pattern as a moderator, but the effect was only marginally significant. Family-of-origin background (parental divorce and/or aggression) was not a significant moderator of prevention effects across the two kinds of services. Implications for defining risk, considering divorce as a positive versus negative outcome, the practice of premarital relationship education, and social policy are discussed.

Predictors of extradyadic sexual involvement in unmarried opposite-sex relationships

Using a sample of unmarried individuals in opposite-sex romantic relationships that was representative of the United States (N = 933), the current study prospectively evaluated predictors of extradyadic sexual involvement (ESI) over 20 months (from 2007-2010). Data were collected with self-report questionnaires via U.S. mail. Participants were 18 to 35 years old, and 34.9% were male. Variables tested as predictors included involved-partner factors such as demographic characteristics, sexual history, and mental health, as well as relationship-related factors including communication, sexual dynamics, and aspects of commitment. Future ESI was significantly predicted by lower baseline relationship satisfaction, negative communication, aggression, lower dedication, absence of plans to marry, suspicion of partners' ESI, and partners' ESI. It was not predicted by sexual frequency, sexual dissatisfaction, or cohabitation status. Although more problems with alcohol use, more previous sex partners, and having parents who never married one another predicted future ESI, there were many involved-partner demographic factors that did not predict later ESI (e.g., gender, age, education, religiosity, having divorced parents, and having children). None of the results were moderated by gender. These results suggest that compared to demographic characteristics, relationship dynamics and negative interactions are more strongly predictive of future ESI. Implications for future research are discussed.
