Attachment Styles, Condomless Sex, and Drugs in HIV-Positive Gay and Bisexual Men

Adult Attachment Anxiety Is Protective Against the Effects of Internalized Homophobia on Condomless Sex Among Young Sexual Minority Men: The P18 Cohort Study

Internalized homophobia, or the internalization of negative attitudes toward one's sexual minority identity, is associated with sexual risk behaviors among young sexual minority men (YSMM). However, the formation and maintenance of secure or insecure socio-emotional bonds with friends, family members, and intimate partners (i.e., adult attachment) may mitigate or exacerbate the negative effects of exposure to internalized homophobia. Nevertheless, little is known about how adult attachment influences the association between internalized homophobia and sexual risk behaviors (e.g., condomless anal sex) among YSMM. Thus, this study examined the potential moderating effect of adult attachment on the association between internalized homophobia and condomless anal sex (CAS) behaviors (i.e., insertive CAS and receptive CAS) among a sample of N = 268 YSMM who participated in the study between June 2015-March 2017 using zero-inflated Poisson regression models. We found that adult attachment anxiety, but not adult attachment avoidance, significantly moderated the association between internalized homophobia and receptive CAS behaviors such that those higher on adult attachment anxiety and internalized homophobia had fewer receptive CAS events over the preceding 30 days as compared to those lower on adult attachment anxiety and internalized homophobia. Research efforts should focus on unpacking the complex associations between adult attachment, internalized homophobia, and sexual risk behaviors among YSMM.

Early parent-child interactions and substance use disorder: An attachment perspective on a biopsychosocial entanglement

This review aims to elucidate environmental and genetic factors, as well as their epigenetic and neuroendocrine moderators, that may underlie the association between early childhood experiences and Substance Use Disorders (SUD), through the lens of parental attachment. Here we review those attachment-related studies that examined the monoaminergic systems, the hypothalamic pituitary adrenal stress response system, the oxytoninergic system, and the endogenous opioid system from a genetic, epigenetic, and neuroendocrine perspective. Overall, the selected studies point to a moderating effect of insecure attachment between genetic vulnerability and SUD, reasonably through epigenetic modifications. Preliminary evidence suggests that vulnerability to SUDs is related with hypo-methylation (e.g. hyper-expression) of high-risk polymorphisms on the monoaminergic and hypothalamic pituitary adrenal system and hyper-methylation (e.g. hypo-expressions) of protective polymorphisms on the opioid and oxytocin system. These epigenetic modifications may induce a cascade of neuroendocrine changes contributing to the subclinical and behavioural manifestations that precede the clinical onset of SUD. Protective and supportive parenting could hence represent a key therapeutic target to prevent addiction and moderate insecure attachment.
