Supportive behaviors in adolescent romantic relationships moderate adrenocortical attunement.

This study investigated dyadic adrenocortical attunement within adolescent romantic relationships. An ethnically diverse sample (42% Latino) of adolescent heterosexual dating couples (N=91 dyads, Mage=16.5 years, SD=0.99) donated eight saliva samples (later assayed for cortisol) over the course of a 3-h laboratory session. Supportive behaviors were coded during a conflict and jealousy interaction task from video recordings, and participants completed pre-and-post task questionnaires. Parallel process latent growth models revealed a strong positive association between the couples' cortisol intercept, indicating that couples show attunement in initial levels of cortisol. Further, observed supportive behavior moderated the strength of the association between dyadic cortisol slopes. The results imply that low levels of supportive behavior predicted stronger adrenocortical attunement in the change in cortisol levels over time between adolescent romantic partners. These findings indicate that even early romantic relationships exhibit coordination of physiological activity. Findings raise the possibility that adrenocortical attunement may be a dyadic pathway through which the proximal social context of early romantic relationships is translated into risk or resilience in health and behavior.

Individual and family predictors of psychological control in parents raising children with type 1 diabetes.

The purpose of this research is to examine how metabolic control, parents' marital conflict, and parental caregiver burden are related to parents' use of psychological control in families raising a child with Type 1 diabetes (T1D). Differences between mothers and fathers are also considered. In this cross-sectional study, parents of 85 children with T1D independently completed self-report questionnaires; metabolic control levels were obtained through patient medical records. Structural equation modeling showed that better metabolic control is related to lower levels of fathers' caregiver burden, and marital conflict is positively related to both mothers' and fathers' ratings of caregiver burden. Mothers' caregiver burden is positively related to their psychological control (a type of parental behavior that threatens children's autonomous thoughts and feelings) and, similarly, fathers' caregiver burden is positively related to their psychological control. Paths in the model differed by parent gender, but there were no crossover effects. Future research is needed to develop new, effective interventions for children with diabetes and their parents, focusing not only on the child but on multiple family systems.

Pornography use: who uses it and how it is associated with couple outcomes.

Very little is known about how pornography use is related to the quality of committed relationships. This study examined associations among pornography use, the meaning people attach to its use, sexual quality, and relationship satisfaction. It also looked at factors that discriminate between those who use pornography and those who do not. Participants were couples (N = 617 couples) who were either married or cohabiting at the time the data were gathered. Overall results from this study indicated substantial gender differences in terms of use profiles, as well as pornography's association with relationship factors. Specifically, male pornography use was negatively associated with both male and female sexual quality, whereas female pornography use was positively associated with female sexual quality. The study also found that meaning explained a relatively small part of the relationship between pornography use and sexual quality.
