Erectile Dysfunction, Suspicious Jealousy, and Partner-Directed Behaviors in Heterosexual Romantic Couples.

Erectile dysfunction (ED) can have negative consequences for men and their intimate partners. The purpose of the present research was to replicate and extend the results of previous studies concerning the connections that ED has with partner-directed behaviors using a sample of heterosexual romantic couples. Specifically, we used an actor-partner interdependence mediation model to examine whether the associations that ED had with men's mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injuries were mediated by suspicious jealousy, but not reactive jealousy. These associations were examined in 113 romantic couples, using men's self-reports, and partner-reports provided by their female partners. Results indicated that suspicious jealousy (but not reactive jealousy) mediated the associations that ED had with men's use of partner-directed behaviors, such that higher levels of ED were associated with men experiencing more suspicious jealousy, which, in turn, was associated with more cost-inflicting mate retention behaviors, benefit-provisioning mate retention behaviors, partner-directed insults, partner-directed violence, and partner-inflicted injury. However, there were some discrepancies between the reports provided by men and women such that these associations emerged more consistently in the partner-reports provided by women than in the self-reports provided by men. Discussion addresses evolutionary implications of these findings, as well as limitations of this research and directions for research concerning ED.

Sexual Communal Strength Partially Mediates the Associations between Mate Retention Behaviors and Relationship Satisfaction.

Mate retention behaviors are associated with several aspects of romantic relationships, but different categories of mate retention behaviors have divergent associations with relationship satisfaction. The present studies examined whether sexual communal strength - which refers to the motivation to meet the sexual needs of one's partner - mediated the associations that benefit-provisioning and cost-inflicting mate retention behaviors had with relationship satisfaction. We investigated the associations that mate retention behaviors had with relationship satisfaction through sexual communal strength using men's self-reports (Study 1) and women's partner-reports (Study 2). We found that sexual communal strength partially mediated the associations that mate retention behaviors had with relationship satisfaction in both studies. Benefit-provisioning mate retention behaviors had a positive indirect association with relationship satisfaction through sexual communal strength in both studies, whereas cost-inflicting mate retention behaviors had a negative indirect association with relationship satisfaction through sexual communal strength in Study 1 but not in Study 2. We explore the reasons why sexual communal strength may play an important role in the connections that mate retention behaviors have with relationship satisfaction.

Narcissism and Exercise Addiction: The Mediating Roles of Exercise-Related Motives.

The present research examined whether the associations that narcissistic personality features had with exercise addiction were mediated by particular motives for engaging in exercise in a large Israeli community sample (N = 2629). The results revealed that each aspect of narcissism was positively associated with exercise addiction. Narcissistic admiration and narcissistic rivalry had similar positive indirect associations with exercise addiction through the interpersonal motive for exercise. However, these aspects of narcissism diverged in their indirect associations with exercise addiction through psychological motives, body-related motives, and fitness motives for exercise such that these indirect associations were positive for narcissistic admiration but negative for narcissistic rivalry. Narcissistic vulnerability had positive indirect associations with exercise addiction through body-related motives and fitness motives that were similar to those observed for narcissistic admiration. These results suggest that exercise-related motives may play important roles in the associations that narcissistic personality features have with exercise addiction. The discussion will focus on the implications of these results for understanding the complex connections between narcissism and exercise addiction.
