Deviant peer affiliation mediates the prospective association from impulsivity to alcohol use in late adolescence.

Introduction: Previous research has found that impulsivity and deviant peer affiliation predict alcohol use among adolescents. However, it remains unclear to what extent these risk factors predict alcohol use in conjunction with one another, and to what extent they predict over and above correlated risk factors, such as pre-existing externalizing problems and sociodemographic characteristics. The present study tested the hypothesis that deviant peer affiliation would mediate the prospective association between impulsivity and alcohol use in adolescence (ages 13-18 years), controlling for a wide range of family and child-level covariates.

The pregnancy compensation hypothesis, not the staying alive theory, accounts for disparate autoimmune functioning of women around the world.

The pregnancy compensation hypothesis provides a mechanistic explanation for the evolution of sex differences in immune system functioning, the excess of women experiencing autoimmune disease, and why this is observed only in industrialized nations; none of which can be explained by the staying alive theory, as proposed by the authors of the target article.

Maternal use of corporal punishment and behavior problems in early childhood: A sibling comparison analysis.

Background: Previous research demonstrates that there are environmental and genetic factors associated with the use of corporal punishment (CP) and children's behavior problems. Thus, it is difficult to disentangle whether CP has a causal effect on children's developmental outcomes.

Objective: This study explored the relationship between maternal use of CP at ages 3-4 years and symptoms of internalizing and externalizing behavior problems between the ages of 6 and 9 years using a sibling comparison design.

Couple Communication Behaviors During Sexual and Nonsexual Discussions and Their Association with Relationship Satisfaction.

The quality of communication between romantic partners has consistently been found to be associated with relationship well-being and stability. Studies on sexual and nonsexual communication, however, have typically assessed communication skills and behaviors using self-report measures. The use of observational methods has several advantages, including the ability to capture and allow for the independent coding of both partners' communication behaviors.

A Typology of Women with Low Sexual Desire.

Low sexual desire is the most common sexual issue reported by women and research suggests that the presentation and experience of low sexual desire may vary considerably between women. This study explored whether women with low desire differ qualitatively from one another based on several key contextual factors theoretically associated with low desire. We collected data from women in long-term relationships (N = 508) using an online platform.
