Between 2004 and 2019, researchers recruited 1,256 young offspring, aged 12–22 at baseline, from the Collaborative Study on the Genetics of Alcoholism (COGA), a large, multigenerational family study on the genetic and environmental influences driving AUD. These offspring were interviewed and their brain function was assessed biannually. The interviews covered participants’ substance use, mental health, and aspects of their home environments, including closeness with their mothers and fathers between ages 12-17. Their P3 and FT responses were measured using a visual task. Researchers also collected data on participants’ binge drinking, impulsiveness (a personality trait known to affect alcohol use problems and relationships with parents), demographic characteristics, and parents’ alcohol and substance use. They used statistical analysis to explore associations between these factors.
Overall, greater closeness with fathers was associated with more robust P3 and FT activity in offspring, while closeness with mothers was linked to less binge drinking. Certain sex differences also emerged. Closeness with fathers was linked to larger P3 in sons but not daughters; closeness with mothers was linked to less binge drinking among daughters but not sons. This may reflect distinct roles of fathers and mothers in child and teen development, and differential parenting of boys versus girls. The findings held independent of other risk factors, including parents’ AUD, substance use problems, socioeconomic status, and offspring impulsiveness.
The study provides compelling evidence that warm, close relationships with parents during adolescence may help build resilience to problematic drinking in offspring negatively affected by family AUD and that this, in part, reflects improved neurocognitive functioning. Aspects of parenting affecting children’s risk of AUD include—and go beyond—drinking behaviors. The researchers conclude that close bonds with parents during the key transitional period of adolescence can substantially attenuate offspring’s tendency toward risky behaviors and addictive disorders, with important sex differences.
