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.

In the early stages of romantic relationships, sexual desire is often intense, but over time, as partners get to know each other, desire tends to decline. Low sexual desire has negative implications for relationship satisfaction and maintenance. Self-expansion theory suggests that engaging in novel activities with a long-term romantic partner can reignite feelings of passion from the early stages of a relationship. Across 3 studies using dyadic, daily experience, longitudinal, and experimental methods, we find evidence for our central prediction that engaging in self-expanding activities with a partner is associated with higher sexual desire. In turn, we found that higher desire fueled by self-expansion is associated with greater relationship satisfaction. Self-expansion, through sexual desire, is also associated with an increased likelihood that couples will engage in sex, and when they do engage in sex, they feel more satisfied with their sexual experiences. We also demonstrate that the benefits of self-expansion for relationship satisfaction are sustained over time, and that the effects cannot be attributed solely to increases in positive affect, time spent interacting with the partner or closeness during the activity. Implications for selfexpansion theory and sexual desire maintenance in relationships are discussed.

Compassionate love has been identified as one of the major types of love experienced in relationships (Berscheid, 2010), but one that has been overshadowed by the study of romantic love. In this article, we review research on compassionate love, a relative newcomer to the close relationships field, and present findings that more fully flesh-out the nature of the experience of this kind of love. We begin by discussing conceptions and measurement of compassionate love. We then present a study on the relation between compassionate love and love styles, with a focus on distinguishing between compassionate love and the agape (altruistic) love style. The literature on individual differences in compassionate love is discussed next. The spotlight then shifts to research on the link between compassionate love and prosocial relationship behaviors, relationship quality, and relationship stability. Differences between compassionate love given versus received also are highlighted. We end with a discussion of what compassionate love “looks like” in the context of a romantic relationship and recommend directions for future research.

The goal of this research was to create a self‐report measure of relational boredom using a prototype approach. In the first study, 2 samples (participants in dating relationships and in marital relationships) generated features of the concept of relational boredom. In Study 2, these features were rated for prototypicality by 2 samples (dating and married). A Relational Boredom Scale was constructed by selecting those features (items) that were rated as most central to the construct. In Study 3, the reliability and validity of the scale were assessed, again with participants in dating and marital relationships. There was evidence that the Relational Boredom Scale is a psychometrically sound measurement instrument.

The goal of this research was to examine relational boredom using a script approach. dating individuals (N = 99; Study 1) and married individuals from the community (N = 62; Study 2) generated causes of boredom in their relationship, associated feelings, and coping strategies. Boredom was seen as caused by a lack of novelty and stimulation and was associated with negative affect (particularly low pleasure, low arousal affect). People reported using active relationallyfocused strategies to cope with boredom. Boredom scripts varied somewhat as a function of individual differences in boredom proneness and relationship satisfaction, but not gender. The findings are discussed in terms of aron and aron's (1986) self-expansion model and gable and reis's (2001) model of appetitive relationship processes.

A common reason why people in ongoing romantic relationships report engaging in sex with their partner—in addition to pursuing their own pleasure—is to meet their partner’s sexual needs. While meeting a partner’s needs with responsiveness and care is crucial in romantic relationships, it is important, especially in the domain of sexuality, that people do not neglect their own needs when meeting the needs of their partner. In a 21-day daily experience study of both members of 122 romantic couples recruited from the community, we tested whether being responsive to a partner’s sexual needs (i.e., high sexual communal strength) and focusing on a partner’s needs while neglecting one’s own needs (i.e., high unmitigated sexual communion) were associated with both partners’ daily sexual and relationship satisfaction. We also tested attention to positive partner-focused and negative self-focused cues during the sexual experience as novel mechanisms of these effects. The results generally showed that on days when people (or their romantic partner) reported higher sexual communal strength, they reported greater attention to positive partner-focused sexual cues and, in turn, both partners experienced greater daily sexual and relationship satisfaction. In contrast, on days when people reported higher unmitigated sexual communion, they reported greater attention to negative self-focused sexual cues and, in turn, experienced lower relationship and sexual satisfaction, although these effects did not extend to their romantic partner. Implications of the results for promoting higher quality sexual experiences and relationships are discussed.

Boredom has been described as a major obstacle to maintaining lasting love (Aron & Aron (1986). However, empirical research on this important challenge to relationship maintenance has been hampered by the lack of an agreed-upon definition of the construct. We tested the hypothesis that relational boredom is amenable to a prototype conceptualization. In study 1, participants provided prototypicality ratings for the features of relational boredom. Features such as ''lack of interest in partner'' and ''no longer exciting'' were considered prototypical of the construct, whereas features such as ''nothing in common'' and ''too similar'' were considered nonprototypical. We confirmed this prototype structure in the remaining studies. In study 2, when information that a couple was experiencing boredom was given, participants were more likely to infer that prototypical, than nonprototypical, features characterized the relationship. In study 3, the prototypical features were verified more quickly than the nonprototypical features in a reaction time task. In study 4, when a relationship was described in terms of prototypical, rather than nonprototypical, features of boredom, participants inferred greater boredom in the relationship. Moreover, these inferences were drawn more strongly for boredom than another negative relational state, namely conflict. Implications of these findings for theorizing and research on relational boredom are discussed.
