Five studies examined whether receiving gratitude expressions from a romantic partner can buffer insecurely attached individuals from experiencing low relationship satisfaction and commitment. In Study 1, the negative associations between attachment avoidance and both satisfaction and commitment were weaker among individuals who perceived that their partner expressed gratitude more frequently. The same pattern was found with attachment anxiety and satisfaction. Study 2 showed that among individuals who perceived high (vs. low) levels of gratitude expressions from the partner, both attachment dimensions were less strongly related to the belief that the partner is low in communal strength, which, in turn, was associated with greater satisfaction and commitment. In Studies 3-5, we examined whether perceptions or a partner's actual gratitude expression can have benefits on insecurely attached individuals' daily satisfaction. Our results indicated that perceived, rather than a partner's self-reported, gratitude expressions were critical to buffering insecurely attached individuals' daily dissatisfaction. Study 5 also provided evidence for long-term benefits of perceiving a partner's gratitude expressions on avoidantly attached individuals' relationship. Perceiving high levels of a partner's gratitude expressions on average enhanced avoidantly attached individuals' feelings of being cared for by the partner 3 months later, which were associated with greater satisfaction and commitment. Results from our meta-analysis indicated that benefits of perceiving a partner's gratitude expressions may be specific to buffering the negative effects of attachment avoidance on satisfaction. Overall, our findings highlight the powerful function of gratitude in insecurely attached individuals' romantic relationships.

Despite the worldwide increase in single-person households, little research has examined what factors contribute to a satisfying single life. We used three data sets ( N = 3,890) to examine how satisfaction with sexual and social aspects of life are linked with single people’s perceptions of marriage and singlehood. Our results suggest that higher sexual satisfaction is associated with less desire to marry (Study 1), stronger beliefs that unmarried people can be happy without marriage (Study 2), and greater satisfaction with singlehood and less desire for a partner (Study 3). All effects in Studies 1 and 3 remained significant controlling for life satisfaction and sexual frequency. Satisfying friendships were associated with variables related to satisfaction with singlehood but not variables related to desire for a partner, whereas no effect was found for satisfaction with family. This study highlights the potential importance of maintaining a satisfying sex life in people’s satisfaction with singlehood.

Although some evidence exists to suggest that single (i.e., unpartnered) individuals are less sexually satisfied on average than are partnered individuals, it is unclear whether the variables correlating with each group’s sexual satisfaction are similar or different. This research sought to examine how desire for and actual engagement in solitary and partnered sexual activities are associated with both groups’ sexual satisfaction. We first conducted a preliminary study ( n = 572) to test and refine existing measures of sexual satisfaction for applicability across relationship status. In two follow-up studies ( N = 1,238), measurement invariance (across relationship status and gender) of the resulting 4-item sexual satisfaction scale was established. Further, results across the studies showed that for singles dyadic sexual desire was negatively related to sexual satisfaction, whereas no significant link was found with solitary desire. For individuals in romantic relationships, having higher sexual desire involving a partner and lower solitary desire were both associated with greater sexual satisfaction. When analyzing participants’ responses on the desired and actual frequency of engaging in specific sexual acts, we found that for both single and partnered individuals, frequent engagement in partnered acts was associated with greater sexual satisfaction. Wanting frequent engagement in partnered acts was associated with lower sexual satisfaction for both groups, but only if the current frequency of engaging in these acts was low. These findings suggest that at least during the COVID-19 pandemic, meeting desires for partnered sex plays an important role in maintaining a sexually satisfying life, regardless of one’s relationship status.

With a growing body of relationship research relying on dyadic data (i.e., in which both members of a couple are participants), researchers have raised questions about whether such samples are representative of the population or unique in important ways. In this research, we used two large data sets (Study 1: n = 5,118; Study 2: n = 5,194) that included participants with and without a romantic partner participating to examine if co-participation status has substantive relationship implications. Results showed that co-participation status predicted breakup even after controlling for other known predictors such as satisfaction, although the effect weakened over time (Study 2). There was also tentative evidence that factors such as conflict may be differentially related to breakup among couples in which one versus both partners participated. These findings raise caution in interpreting effects found in dyadic studies and highlight the need to be mindful of potential bias in recruitment.

Singlehood, defined as not being in a romantic relationship, is becoming increasingly common worldwide. Despite this, research on singlehood has not received remotely equivalent research attention as romantic relationships. Well-being research that has explicitly included singles has focused on whether coupled versus single people are more satisfied with their lives. However, these between-group comparisons have not attended to within-group variability among singles that can point to when and for whom singlehood is associated with thriving. In this review, we document findings from the emerging field of singlehood studies to highlight what is and is not known about factors that are associated with the well-being of single individuals from a within-group perspective. Our review examines (a) intrapersonal factors (characteristics of the individual), (b) interpersonal experiences (qualities of one’s social relationships and experiences), and (c) societal influences (features related to one’s broader social or cultural context) related to well-being in singlehood. We conclude by offering future directions for the conceptualization of and research on singlehood with the goal of promoting a thorough and inclusive perspective.
