Article
There are a variety of conditions under which religiosity may be positively or negatively associated with sexual and relationship satisfaction. To better understand these conditions, we conducted two studies using two separate samples: one with individuals (1,695 individuals), and one with couples (481 dyads), to test how sexual sanctification and...
Article
Full-text available
A central feature of couple relationships research is the use of self-report measures of relationship satisfaction. Despite the widespread use of such measures in couples’ research, scholars have raised critical questions about satisfaction-focused assessment, including concerns about taking an ontologically individualistic focus. Moving beyond ont...
Article
Full-text available
Most research has shown that sexual satisfaction in long-term relationships tends to decline over time. Studies showing the average trajectory, however, are limited by only assessing one slope. With longitudinal data from the Flourishing Families Project, Marital Instability Dataset, and the Iowa Youth and Families Project, we utilized growth mixtu...
Article
While scholars have increasingly explored associations between pornography use and relationship quality, this research has been limited by various methodological and conceptual problems. One specific limitation noted by previous scholars is the assumption that such associations are always linear. Using a national sample of 3750 individuals in commi...
Article
Full-text available
Previous scholars have found that when individuals feel that pornography use is uncontrollable, it is linked to more extreme negative outcomes than frequency of use. With a Mechanical Turk sample of 1421 individuals, we used structural equation modeling to evaluate how multiple aspects of sexual desire (sexual drive and dyadic desire) and multiple...
Article
Objective To provide a more comprehensive understanding of couple relationship satisfaction, commitment, and the dynamic between the two over the transition to parenthood. Background The transition to parenthood is an ideal time to concurrently study relationship satisfaction and commitment, as this period is filled with familial transitions such...
Article
In this study we explored the sexual response process in couple relationships. With a U.S. sample of 383 mixed-sex couples we found seven different classes of couple sexual response using Dyadic Latent Class Growth Analysis for ratings of self and partner about their most recent sexual experience. These classes ranged from synchronous High Arousal...
Article
Background The transition to parenthood is associated with changes to new parents’ mood and sexual health. Sexual dysfunction—problems with sexual function accompanied by sexual distress (i.e., worries and concerns about one’s sex life)—is linked to poorer overall health, yet few studies have examined how sexual dysfunction unfolds for couples duri...
Article
Background Curvilinearity has been found for sexual frequency, but research has not examined whether curvilinear associations exist for other aspects of sexual relationships like orgasm consistency. Aim We examined whether there is curvilinearity and the nature of that curvilinearity between orgasm consistency and sexual and relational satisfactio...
Article
Background: While links between pornography use and couple relational well-being have been the subject of multiple research studies, less attention has been paid to the associations between pornography use and specific sexual behavior within the relationship. Aim: This study aimed to explore associations between each partner's pornography use, sex...
Article
Full-text available
Harmonious, obsessive, and inhibited sexual passion comprise the Triadic Model of Sexual Passion. Research has shown that together they play an important role in sexual and relationship satisfaction. Little is known, however, about the factors that predict the likelihood of having these types of passion expression. Using a Mechanical Turk sample of...
Article
Full-text available
Objectives The objectives were to examine the recently emerging topic of sexual passion in relationships by addressing four research questions: Was sexual passion in a relationship distinct from general passion for sexuality, general passion in life, and romantic passion? Did the different sexual passion styles in a relationship meet the criteria f...
Article
Sexual well-being is an important contributor to romantic relationship quality, health, and quality of life, yet couples face significant disruptions to their sexuality during the transition to parenthood. While there is evidence of variability in the sexual well-being of new parents, distinct classes of dyadic trajectories have not been establishe...
Article
Religiosity can influence sexual satisfaction both positively and negatively. To test positive and negative mechanisms, we assessed how religiosity is indirectly associated with sexual satisfaction through sexual sanctification and inhibited sexual passion. We sampled individuals from Amazon's Mechanical Turk (N = 1,695, Study 1) and mixed-sex dyad...
Article
Attachment insecurity is negatively linked to sexual satisfaction in committed relationships, but we have much to learn about the specific mechanisms underlying this connection. With a sample of 1,421 participants from Amazon’s Mechanical Turk, we used structural equation modeling to explore whether sexual passion expression (harmonious, obsessive,...
Article
Numerous scholars have claimed that positive ethical traits such as virtues are important in human psychology and behavior. Psychologists have begun to test these claims. The scores of studies on virtue do not yet constitute a mature science of virtue because of unresolved theoretical and methods challenges. In this article, we addressed those chal...
Article
Pornography use is now considered a normative sexual activity, including for partnered individuals. Although there are documented positive and negative effects of pornography use on romantic relationships, studies to date suffer from key limitations, narrowing their clinical relevance. Most rely on vague recall measurement that may inadequately cap...
Article
Full-text available
To understand how non-university emerging adults think about marriage and how these beliefs differ by gender, we used a diverse national quantitative sample (Study 1, n = 667) from the United States and qualitative data (Study 2, n = 63) from participants of diverse geographic locations, also from the United States. Women and men valued marriage as...
Article
In this study we explored why there are sometimes conflicting findings regarding the influence of past sexual experience on relationships. Consequently, we studied the effects of body-esteem and religiosity on sexual experience in two relational contexts (casual or committed relationships) and how all of these variables were associated with life sa...
Article
Full-text available
Historically the male sexual response cycle was seen as uniform and used as the standard for women. Recent research has suggested that men’s sexual response cycle may vary more than previously thought. We asked 520 sexually active men between the ages of 18–73 to report on their sexual desire and arousal patterns during their last sexual experience...
Article
Research exploring the correlates, moderators, and potential consequences of viewing pornography for romantic couples has surged in recent years. Research in this area has primarily focused on the question of whether viewing pornography for either partner (or together) is related to enhanced, diminished, or has no effect on relational well-being. H...

Full-text available
Because early initiation of sexual behavior can lead to negative health outcomes, it is important to understand the influence of family of origin (FOO) on adolescent sexual debut. This brief report explores the relationship between time spent living with both biological parents, overall quality of FOO experience, and various sexual behaviors (vagin...
Conference Paper
Full-text available
Recently Galovan and Schramm (2018) argued for a new perspective to understand healthy, vibrant relationships. They argued for a strongly relational view of the self that integrates who one is with the way they respond to others in any given situation. They argued that from a strong relationality perspective, “who we are is who we are in relation t...

Article
Full-text available
Although research has suggested a net negative influence of sexual media on sexual quality, enough researchers have found results suggesting that sexual media has no effect or a positive influence that the matter warrants further investigation. We present an organizational framework utilizing primarily the acquisition, activation, application model...
Article
Spouses perceiving that they have shared power in marriage has been linked to higher marital quality and attachment security. Existing research, however, is limited in assessing how these perceptions influence both spouses and whether these influences endure over time. To address these limitations, we analyzed the longitudinal relationship reports...
Article
Research has suggested women’s sexual response cycle may vary more than previously thought. We asked 769 sexually active women between the ages of 18–70 to report on their sexual desire and arousal patterns during their last sexual experience. Using a latent class mixture model from retrospective sexual response data, we found six classes of desire...
Article
With a Mechanical Turk sample of 1,614 sexually active individuals (62.6% women, 85% heterosexual, mean age of 34.47 years) who had been in a committed sexual relationship for at least two years, we used structural equation modeling to better understand how global religiosity may indirectly influence sexual satisfaction. Because religiosity has bee...
Article
Most previous research on the associations between pornography use and relational well-being has utilized individual data sets that have limited scholars’ ability to truly understand the dyadic nature of pornography use within romantic couples. Using a dyadic data set of 240 committed heterosexual couples from the United States, we explored actor a...
Article
The purpose of this study is to discuss the need for a new triadic model of sexual passion in relationships and to present the preliminary psychometric properties of a scale designed to measure these three approaches to passion (harmonious, obsessive, and inhibited) for use in clinical and scholarly work. Existing theory and measures of general pas...
Article
Qualitative data analysis of in-depth interviews with 28 Latter-day Saint families (N = 67 individuals) revealed several recurring themes and concepts. Sharing an “eternal perspective” (i.e., shared belief in eternal marriage, eternal progression, eternal life, and eternal family) emerged as the overarching theme. In connection with the life streng...
Article
Background: Self-reported orgasm, perception of partner's orgasm, and misperception of partner's orgasm have each been correlated with individual sexual and relationship satisfaction, but these associations have rarely included dyadic data, have not fully accounted for potentially confounding variables such as sexual communication, and have never...
Article
Full-text available
Despite recent policy initiatives and substantial federal funding of individually oriented relationship education programs for youth, there have been no meta-analytic reviews of this growing field. This meta-analytic study draws on 17 control-group studies and 13 one-group/pre-post studies to evaluate the effectiveness of relationship education pro...
Article
Recent research has suggested that sexual content and sexual satisfaction are multifaceted. Yet, no study has parceled out how distinct aspects of sexual content may be associated with multiple aspects of sexual satisfaction. In this study of 858 individuals in a committed romantic relationship, we used structural equation models to evaluate how tw...

We surveyed 592 individuals (357 males) who were making efforts to stop their pornography use to understand how perceptions of their behavior as an addiction related to individual and relationship outcomes.
Article
While the scholarly literature on pornography use is growing, much of this literature has examined pornography use as a static feature that does not change. Despite this trend, pornography use, like most sexual behaviors, is likely best viewed as a dynamic feature that may shift across the developmental life span. Using a sample of 908 adults from...
Article
Limited research exists concerning pornography’s influence on emerging adult’s relationship trajectories, with no research examining how pornography use predicts emerging adults’ beliefs about marriage. The study includes cross-sectional results of 568 emerging adults and longitudinal results of 142 participants who were followed from the original...
Article
Sexuality is presumptively and observably a powerful core element of the human pair-bond relationship. Technological advances of the last half-century have made media a dominant cultural and developmental presence, including scripting sexual relationship attitudes and behavior. Theoretically and empirically, we examine loneliness as it relates to p...
Article
Recent research on pornography suggests that perception of addiction predicts negative outcomes above and beyond pornography use. Research has also suggested that religious individuals are more likely to perceive themselves to be addicted to pornography, regardless of how often they are actually using pornography. Using a sample of 686 unmarried ad...
