Latino Mother/Daughter Dyadic Attachment as a Mediator for Substance Use Disorder and Emotional Abuse

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.

The Association Between Social Support and Psychological Distress in Latina Mothers Living in Miami-Dade County, Florida

BACKGROUND

This study analysed the relationship between social support and psychological distress in Latina women in Miami-Dade County. Acculturation was examined as a modifying factor.

METHODS

A 2005 data set from interviews of 155 Latina mothers in Miami-Dade County, from mother-daughter dyads, was analysed. Social support was measured using the Interpersonal Support Evaluation List (ISEL) score. Psychological distress was based on self-reporting symptoms of depression, anxiety, or suicidality. Acculturation was based on English proficiency and length of U.S. residency.

RESULTS

Compared to those with high social support, women with low social support had greater odds of reporting psychological distress (odds ratio = 7.8 [95% CI 2.70-22.10]). Acculturation did not modify the association (p=0.74).

CONCLUSIONS

Social support was inversely associated with psychological distress among Latina women. Acculturation was not an effect modifier, likely due to inadequate power. The study has clinical implications for mental illness prevention in this population.
