This qualitative study seeks to examine one major aspect (or "pillar") of Islam, prayer (salat). Prayer is a widely practiced religious act; however, a dearth of social science research exists on prayer in relation to Muslim couples and families. The influence of prayer among Muslim couples, marriages, and family life is explored to better inform social work practice in working with American Muslim families. Specifically, we address: (a) prayer during courtship, (b) prayer as a unifying influence in marriage, (c) "a prayer for everything"(even sexual intimacy), and (d) prayer as "the most important foundation"for family relationships. Supportive primary data and social work implications are presented.

We investigated how power dynamics in close relationships influence the tendency to devote resources to the pursuit of goals valued by relationship partners, hypothesizing that low (vs. high) power in relationships would lead individuals to center their individual goal pursuit around the goals of their partners. We study 2 related phenomena: partner goal prioritization, whereby individuals pursue goals on behalf of their partners, and partner goal contagion, whereby individuals identify and adopt as their own the goals that their partner pursues. We tested our ideas in 5 studies that employed diverse research methods, including lab experiments and dyadic studies of romantic partners, and multiple types of dependent measures, including experience sampling reports, self-reported goal commitment, and behavioral goal pursuit in a variety of goal domains. Despite this methodological diversity, the studies provided clear and consistent evidence that individuals with low power in their relationships are especially likely to engage in both partner goal prioritization and partner goal contagion.

Extradyadic sex is prevalent in adult romantic relationships and it can have numerous negative consequences. It can negatively affect relationship functioning and makes both members of a romantic dyad more susceptible to particular health risks. The present research provides evidence for an association between problem drinking and extradyadic sex. In two studies, participants completed measures of problem drinking, extradyadic sex, relationship satisfaction, and social desirability. In Study 1 (N = 353), problem drinking predicted higher rates of extradyadic sex controlling for sex, age, relationship satisfaction, and social desirability. In Study 2, this finding replicated both cross-sectionally (N = 500) and prospectively (N = 384), controlling for Time 1 extradyadic sex. Moreover, a majority of participants who engaged in extradyadic sex did not disclose this information to partners and a significant minority did not use a condom during the extradyadic incident.

Prayer is a widely practiced religious behavior. Research has associated prayer with various physical, psychological, and relational benefits. This study used in-depth, interview-based qualitative methods to explore how prayer may foster improvement in married individuals as well as in couples’ relationships in a richly diverse sample of 184 religious couples (N = 368 individuals). Qualitative data analyses revealed the following related themes: (a) prayer is a catalyst for change; (b) prayer facilitates humility and positivity; (c) prayer facilitates communication and understanding among couples; and (d) prayer unifies couples and helps in resolving conflict. Illustrative and supportive primary data are presented in connection with each theme. Implications of the findings are discussed.

Relationship self-efficacy (RSE) is the belief that one can resolve relationship conflicts, and it may lead victims of situational violence to remain in their relationships because they expect to minimize subsequent violence. Indeed, a longitudinal study of two samples of college students demonstrated that RSE moderates the effects of victimization on relationship dissolution; intimate partner violence (IPV) victimization was positively associated with dissolution among intimates low in RSE but was unassociated with dissolution among intimates high in RSE. Interestingly, although RSE was negatively associated with dissolution among victims, it was associated with experiencing less subsequent IPV in one sample. Ultimately, whether victims' RSE is adaptive may depend on the extent to which any minimization of conflicts eliminates violence.

Internet pornography is a multi-billion-dollar industry that has grown increasingly accessible. Delay discounting involves devaluing larger, later rewards in favor of smaller, more immediate rewards. The constant novelty and primacy of sexual stimuli as particularly strong natural rewards make Internet pornography a unique activator of the brain's reward system, thereby having implications for decision-making processes. Based on theoretical studies of evolutionary psychology and neuroeconomics, two studies tested the hypothesis that consuming Internet pornography would relate to higher rates of delay discounting. Study 1 used a longitudinal design. Participants completed a pornography use questionnaire and a delay discounting task at Time 1 and then again four weeks later. Participants reporting higher initial pornography use demonstrated a higher delay discounting rate at Time 2, controlling for initial delay discounting. Study 2 tested for causality with an experimental design. Participants were randomly assigned to abstain from either their favorite food or pornography for three weeks. Participants who abstained from pornography use demonstrated lower delay discounting than participants who abstained from their favorite food. The finding suggests that Internet pornography is a sexual reward that contributes to delay discounting differently than other natural rewards. Theoretical and clinical implications of these studies are highlighted.

Four studies measured or manipulated beliefs in free will to illuminate how such beliefs are linked to other aspects of personality. Study 1 showed that stronger belief in free will was correlated with more gratitude, greater life satisfaction, lower levels of perceived life stress, a greater sense of self-efficacy, greater perceived meaning in life, higher commitment in relationships, and more willingness to forgive relationship partners. Study 2 showed that the belief in free will was a stronger predictor of life satisfaction, meaning in life, gratitude, and self-efficacy than either locus of control or implicit person theory. Study 3 showed that experimentally manipulating disbelief in free will caused a reduction in the perceived meaningfulness of life. Study 4 found that inducing a stronger belief in free will caused people to set more meaningful goals for themselves. The possible concern that believers in free will simply claim all manner of positive traits was contradicted by predicted null findings with regard to sense of humor, empathy, and self-rated attractiveness. Taken together, the present studies show that the belief in free will is a strong predictor of several positive traits and outcomes.

The positive impact of active–constructive responding (i.e., showing enthusiasm) to the sharing of good news (i.e., capitalization attempts) on relationship well-being is well documented. The objective of this research was to determine whether individuals in a close relationship benefit from training to increase active–constructive responding to partner capitalization attempts and to document its impact on relationship well-being. Compared with a joint activity control group, individuals who received training in providing active–constructive responses perceived a greater amount of gratitude from their study partner and perceived their study partner as having greater relationship satisfaction; however, there were no significant differences in reported relationship satisfaction or gratitude expression. Gratitude receipt from a study partner mediated the relationship between experimental condition and perceived study partner relationship satisfaction. These results are discussed in terms of their potential impact on interventions and future research.

Religiousness is reliably associated with lower substance use, but little research has examined whether self-control helps explain why religiousness predicts lower substance use. Building on prior theoretical work, our studies suggest that self-control mediates the relationship between religiousness and a variety of substance-use behaviors. Study 1 showed that daily prayer predicted lower alcohol use on subsequent days. In Study 2, religiousness related to lower alcohol use, which was mediated by self-control. Study 3 replicated this mediational pattern using a behavioral measure of self-control. Using a longitudinal design, Study 4 revealed that self-control mediated the relationship between religiousness and lower alcohol use 6 weeks later. Study 5 replicated this mediational pattern again and showed that it remained significant after controlling for trait mindfulness. Studies 6 and 7 replicated and extended these effects to both alcohol and various forms of drug use among community and cross-cultural adult samples. These findings offer novel evidence regarding the role of self-control in explaining why religiousness is associated with lower substance use.

To forgive someone is to forsake vengeance. However, vengeful behavior could also be decreased by motivational states that promote avoiding aggression. Disgust sensitivity is one such state; elevated levels of disgust sensitivity are associated with less aggression. Heightened disgust sensitivity may therefore relate to low levels of vengeance. Using data from a longitudinal study (N = 186), we applied Structural Equation Modeling (SEM) techniques to examine the cross-lagged effects of disgust sensitivity on vengeance toward a close friend. Controlling for initial levels of vengeance, disgust sensitivity predicted lower vengeance one month later. This research highlights the potential positive role of disgust sensitivity in promoting relationship well-being through its association with vengeance.

The viability of using brief observations of behavior (thin slicing) to identify infidelity in romantic relationships was examined. Two studies supported the hypothesis that observers can accuratelsy identify people who are cheating on their romantic dating partner based on thin slices of observed behavior. In Study 1, raters were able to accurately identify people who were cheating on their romantic dating partner after viewing a short 3- to 4-min video of the couple interacting. Study 2 replicated this finding and identified possible variables that may mediate the relation between coder's ratings and participants' actual reported infidelity. Commitment and trustworthiness were found to be mediators of this relation. These results are discussed in terms of application and future research.

In a series of five studies we examined the relationship between sharing positive experiences and positive affect using a diary method (Study 1) and laboratory manipulations (Studies 2 and 3). All of these studies demonstrated that sharing the positive experience heightened its impact on positive affect. In Study 4, we conducted a four-week journal study in which the experimental participants kept a journal of grateful experiences and shared them with a partner twice a week. Control participants either kept a journal of grateful experience (without sharing), or kept a journal of class learnings and shared it with a partner. Those who shared their positive experiences increased in positive affect, happiness, and life satisfaction over the course of four weeks. Study 5 showed that those who received an "active-constructive" response to good news (enthusiastic support) expressed more positive affect than participants in all other conditions, indicating that the response of the listener is important. In sum, our findings suggest that positive affect, happiness, and life satisfaction reach a peak only when participants share their positive experiences and when the relationship partner provides an active-constructive response.
