Associations Between Parental Alcohol Use and Parenting Practices: A Systematic Review

Parental practices strongly influence offspring development, and parental alcohol use may affect parenting behavior. However, most studies have focused on child-related outcomes. This review instead examined associations between parental drinking and parenting practices. Following PRISMA guidelines, a systematic search in MEDLINE, PsycINFO, Embase, and Scopus identified 9053 articles. Of these, 222 full texts were screened by two reviewers, and 77 were included for critical appraisal. After quality assessment, 68 studies published between 1991 and 2026 were reviewed. Studies were included if they (i) measured parental alcohol use as a predictor and parenting practices as an outcome, (ii) involved offspring under 20 years, (iii) had a quantitative design, (iv) were peer-reviewed and published in English, and (v) excluded pregnancy measures and alcohol/parenting treatment interventions. Parenting factors (e.g., parent-child relationship, monitoring, communication, discipline, conflict, abuse) were categorized and grouped into general and alcohol-specific practices. Parental drinking was categorized into alcohol use disorders (AUD) and non-dependent alcohol use. Sixty-four studies reported at least one significant association between parental drinking and poorer parenting practices. Mixed results were observed for non-dependent drinking and alcohol-specific parenting. Some associations varied with parental gender. Overall, different drinking patterns appear to be linked to impaired parenting quality. Despite being the most common pattern of alcohol use, non-dependent drinking remains understudied in parenting research. The present review highlights several critical gaps in the literature, particularly regarding the relationship between non-dependent drinking, maternal AUD, and parenting practices. Moreover, contextual factors, such as socioeconomic status and gender differences, are insufficiently explored, limiting the understanding of heterogeneity in risk and outcomes. Future research would benefit from employing robust longitudinal designs and expanding geographical representation, in order to capture variation across sociocultural contexts and enhance the generalizability of findings.
