A Latent Profile Analysis of Need Fulfillment in Romantic Relationships
Do people have their psychological needs fulfilled uniformly or unevenly within romantic relationships? We measured fulfillment of seven psychological needs and used latent profile analysis to identify potential heterogeneity in need fulfillment (NF) across two convenience samples: a sample of dating college students (Study 1: N = 688) and a sample of cohabiting participants recruited from Prolific (Study 2: N = 294). Five profiles consistently e…
How Do Invested Partners Become Invested? A Prospective Investigation of Fledgling Relationship Development
Investment—the feeling that one has put considerable resources into a relationship—is theorized to play a key role in relationship persistence. Yet, the development of investment is not well-understood. We recruited 256 individuals in new dating relationships and surveyed them each week for up to 25 weeks. This design allows us to test underlying theoretical assumptions about how people become invested in new dating partners. Some assumptions, su…

Are We Still Friends If You Are No Longer Single? The Impacts of a Friend Entering a New Romantic Relationship
When a previously single close friend enters a romantic relationship, the friendship may be impacted as the friend shifts time and attention toward the romance. The current research investigated whether need fulfillment, uncertainty, and negative affect change when a person's close friend begins a new romantic relationship. In Study 1, participants ( N = 334) retrospectively reported their perceptions of a best friendship before and after the bes…
A Latent Profile Analysis of Reasons for Cohabitation
We used latent profile analysis to further understand the heterogeneity of individuals' reasons for cohabitation. Using two samples of cohabitors ( N = 563), we measured the extent to which cohabitors endorsed three reasons for cohabiting (time together, testing, and convenience). We identified six profiles: low levels of time together and testing and an average level of convenience (Profile 1; moderately convenience‐driven), high levels of time …
Changing for the worse: The effects of attachment anxiety on perceived self-adulteration
In romantic relationships, people's self-concepts (i.e., a person's conceptualization of themselves) change. They expand to incorporate partners' characteristics and contract to eliminate no longer relevant self-characteristics. This process is a sign that a couple is growing closer and is associated with positive outcomes. However, not all incorporated characteristics are positive. Some individuals are more likely to have selves that expand to i…
Single while partnered: Perceived relationship status in various contexts
Why are you single: Examining the influence of reasons for being single on the stereotypes associated with single adults
In the current work, consisting of 1 correlational study and 1 experiment ( N = 534), we examined the societal acceptability of different reasons for being single and investigated whether there are differences in perceptions of single adults depending on the reason that they are single. In Study 1, we found that reasons for being single vary regarding how acceptable they are considered by others. Drawing on the stereotype content model, in Study …
Direct-proactive communication and the post-infidelity stay-leave decision
Research at the intersection of infidelity and communication has primarily focused on how partners communicate post-infidelity. However, researchers have yet to investigate whether direct-proactive communication (i.e. having an intentional conversation with one’s partner about attitudes toward infidelity prior to its occurrence) can influence victims’ stay-leave decision-making process in response to the transgression. We conducted two studies (t…
The effects of conflict resolution styles on perceived relational self-concept change
No romantic relationship, no matter how fulfilling and satisfying it may be, is without conflict. We sought to understand how the conflict resolution styles a person uses in their relationship are associated with their perception of their self. Specifically, we examined negative conflict resolution styles and their influence on perceived relational self-concept degradation. In two studies (Ns = 272 and 184), we predicted and found that the more f…
Committed to staying single: Adapting the investment model of commitment processes to study singlehood
In the current work, we adapt the investment model of commitment processes for single adults. Across two cross-sectional studies using undergraduate and internet samples (total N = 647), we tested whether the same factors that predict relationship commitment (investment, satisfaction, and quality of alternatives) also predict commitment to singlehood. In line with this theoretical model, we found that singlehood satisfaction and investment in sin…
Breaking‐up is hard to study: A review of two decades of dissolution research
The dissolution of romantic relationships can be conceptualized in many ways, from a distressing event or a consequential life decision to a metric of a relationship's success. In the current review, we assess how relationship science has approached dissolution research over roughly the past 20 years. We identified 207 studies (from 195 papers) published between 2002–2020 that captured relationship dissolution events and coded the papers for rele…
When one's partner wants out: Awareness, attachment anxiety and accuracy
Can a person tell whether their romantic partner wants to break up and, if so, how is such accuracy associated with their own attachment anxiety? We examined these questions by proposing and assessing the construct of perceived partner dissolution consideration (PPDC), including its validity. We then assessed the extent to which partners were accurate in their perceptions of each other's dissolution consideration, focusing on the perceiver's atta…
Social isolation and subclinical vascular pathways to cerebrovascular disease
Social isolation and lack of social support are risk factors for cardiovascular and cerebrovascular disease (CVD). This study explored the relationship between measures of social support and subclinical measures of CVD risk. 58 healthy adults ages 18 to 85 years participated in this study. The Berkman-Syme Social Network Inventory (SNI) was used to assess social isolation, with higher scores signifying less isolation. Social support was defined u…

Discrimination is not just Black and White in romantic relationships: A consideration of perspective taking and self-expansion
531), we found that partners who engaged in perspective taking when discrimination was salient experienced greater positive self-expansion, which in turn led to greater reports of relationship quality. Collectively, these results suggest that perspective taking provides one process by which interracial relationships can be fortified against the adversity of racial discrimination.

The influence of perspective-taking on stress during discrimination in interracial relationships
Interracial couples experience stressors that can negatively impact their relationship quality, such as racial discrimination. In dyads in which one partner identifies as White and the other identifies as Black or Hispanic, the stress due to racial discrimination is associated with differential alternatives: The White partner can end the relationship to stop their experience with the stress of racial discrimination, but Black or Hispanic partners…
The Reasons People Think About Staying and Leaving Their Romantic Relationships: A Mixed-Method Analysis
Across three studies (total N = 993) with diverse methodologies (i.e., experimental studies, longitudinal in vivo sampling), we found that there are distinct reasons why individuals believe their romantic relationship will become, or did become, less committed, and reasons why individuals believe their relationships will become, or became, more committed. Whereas the strongest endorsed reasons to stay (e.g., satisfaction) are the same as the stro…
Machine learning uncovers the most robust self-report predictors of relationship quality across 43 longitudinal couples studies
Significance What predicts how happy people are with their romantic relationships? Relationship science—an interdisciplinary field spanning psychology, sociology, economics, family studies, and communication—has identified hundreds of variables that purportedly shape romantic relationship quality. The current project used machine learning to directly quantify and compare the predictive power of many such variables among 11,196 romantic couples. P…
A longitudinal study of friends with benefits relationships
Friends with benefits relationships (FWBRs) uniquely combine friendship with sexual activity but differ from romantic relationships in that they may be less likely to be exclusive or long lasting. A longitudinal analysis of the trajectory of FWBRs is presented, in which participants in FWBRs at Time 1 reported on their relationship outcomes at Time 2 ( N = 192). Results demonstrated that a plurality of FWBRs transitioned into having no relationsh…
When Beliefs Lead to (Im)Moral Action: How Believing in Torture's Effectiveness Shapes the Endorsement of Its Use
Does believing in torture's effectiveness shape the endorsements of its use? Using a multimethod approach across six studies, we provide converging evidence that efficacy beliefs can help increase understanding of individual differences and situational influences on torture support. Studies 1a and 1b found that torture opinions contained more efficacy‐based language than other types of harm and that people relied more on torture efficacy than tor…
