The intuition behind supervised teen drinking is plausible on its surface: introducing alcohol at home, in controlled amounts, might satisfy curiosity and teach moderation before peer pressure enters the picture. The data from three decades of prospective cohort research does not support this narrative. The Australian Parental Supply of Alcohol Longitudinal Study (APSALS), which followed 1,927 families from grades 7 through 12, found that adolescents who received alcohol exclusively from their parents had 2.58 times the odds of binge drinking, 2.53 times the odds of alcohol-related harm, and 2.51 times the odds of alcohol use disorder symptoms compared to adolescents who received no alcohol from any source (Mattick et al., Lancet Public Health, 2018). Critically, those supplied only by parents were twice as likely to begin accessing alcohol from other sources the following year — the supervised exposure did not contain the behaviour, it accelerated it.
The cross-jurisdictional comparison by Smolkowski and colleagues (2011) is particularly useful for this decision frame because it provides directly comparable child-harm rates across two policy environments that map onto parental approaches. In Victoria, Australia — where supervised home drinking was normative and two-thirds of students reported it by grade 8 — 36% of students experienced harmful alcohol consequences by grade 9. In Washington State, where zero-tolerance norms prevailed and only 35% reported supervised drinking, the rate was 21%. The gap is not merely cultural: the same study found that adult-supervised drinking settings were associated with higher harmful-consequence rates within both populations. A meta-analysis pooling 7 prospective studies across Sweden, the USA, the Netherlands, and Australia found a pooled odds ratio of 2.00 (95% CI 1.72–2.32) for risky drinking among adolescents supplied alcohol by parents versus those not supplied (Mattick et al., IJERPH, 2017).
Under Gilovich and Medvec’s temporal regret framework, actions generate more intense short-term regret when their consequences materialise quickly — and parental alcohol supply consequences tend to appear within one to three years. The action-dominates pattern is consistent with the evidence: parents who gave supervised access and watched their child develop problem drinking have a clear counterfactual (I could have said no) that is cognitively vivid. Parents who maintained strict prohibition and worry their child drinks covertly face a murkier counterfactual. The proxy gap between 36% and 21% represents a 15-point differential in immediate child harm, not a direct bilateral regret survey. Both sides carry real uncertainty: a minority of prohibition-context adolescents become drinkers anyway, and a minority of supervised-access adolescents show no problem trajectory. The evidence does not justify categorical certainty in either direction — it justifies noting that, on average, the supervised-access route produced more measurable harm.

Smolkowski et al. (2011), Prevention Science 12(3):250–263. Prospective cohort of 1,945 grade-7 students (989 females) from Washington State and Victoria, Australia; analysis sample 1,888. Victoria students—where parental supervised drinking was normative and common (66% reported supervised drinking by grade 8)—experienced a 36% rate of harmful alcohol consequences by grade 9. This covers eight harms: blackouts, injuries, loss of control, and violent behaviour. Used here as the action-side regret proxy: parental decision to allow supervised access is judged by whether the child suffered measurable alcohol-related harm within 3 years. No large-scale survey directly asks parents whether they regret giving supervised access.
[2]The Lancet Public Health — Association of parental supply of alcohol with adolescent drinking, alcohol-related harms, and alcohol use disorder symptoms: a prospective cohort study
Revisado por pares
Adolescents receiving alcohol exclusively from parents had OR 2.58 (95% CI 1.96–3.41) for binge drinking, OR 2.53 (1.99–3.24) for alcohol-related harm, and OR 2.51 (1.46–4.29) for AUD symptoms vs no supply
Extracto
“"Providing alcohol to children is associated with alcohol-related harms" with no protective effect demonstrated. Parental supply only was associated with significantly elevated odds of binge drinking (OR 2.58), alcohol-related harm (OR 2.53), and alcohol use disorder symptoms (OR 2.51) compared to no supply from any source.

Mattick et al. (2018), Lancet Public Health 3(2):e64–e71. APSALS cohort, n=1,927 families, grades 7–12, Sydney/Perth/Hobart, 2010–2016. Adjusted odds ratios compare parental-supply-only group vs no-supply group controlling for multiple confounders. These ORs corroborate the Smolkowski harm-rate figure as the primary proxy. The OR 2.53 for alcohol-related harm among parental-supply recipients is directionally consistent with the 36% vs 21% raw rates across jurisdictions in Smolkowski.

UNSW/NDARC media release accompanying the Mattick et al. (2018) Lancet Public Health APSALS paper cited directly above (same cohort, n=1,927 families). Confirms the body-text "cross-over" claim: parental-only supply in a given year predicted a higher rate of subsequently sourcing alcohol from non-parental channels the following year — i.e. supervised access did not substitute for or delay access via other sources.

Same Smolkowski et al. (2011) cohort, Washington State subsample (n=874 of 1,888 total). Washington State enforces strict zero-tolerance underage alcohol laws; parental supervised drinking was reported by only 35% of students by grade 8 vs 66% in Victoria. The 21% harm rate in the prohibition-norm context is the inaction-side proxy: parents who maintained prohibition saw lower rates of immediate alcohol-related harm in their children.

Mattick et al. (2017), Int J Environ Res Public Health 14(3):287. Meta-analysis of 7 prospective longitudinal studies (6 in the pooled OR), sample sizes 428–2,625. The pooled OR 2.00 supports the no-supply (prohibition) inaction side as having roughly half the downstream risky drinking risk. The review notes methodological heterogeneity and cautious causal inference, consistent with the proxy-only framing of this entry.
Advertencias
Ambos lados usan tasas de daño infantil como proxies para el arrepentimiento parental, no encuestas directas que pregunten a los padres si lamentan su decisión de suministro de alcohol. Ningún estudio a gran escala ha rastreado prospectivamente el arrepentimiento reportado por los padres sobre el acceso supervisado versus prohibido. Las muestras de Victoria (proxy de acción) y el estado de Washington (proxy de inacción) provienen de diferentes ambientes culturales y de política, por lo que la comparación 36% vs 21% refleja parcialmente el contexto político más que únicamente la decisión parental. Los odds ratios APSALS de Mattick et al. (2018), y el OR meta-analítico 2,00 de Mattick et al. (2017), corroboran la dirección del efecto pero no son medidas de arrepentimiento parental. Todos los estudios son observacionales; el confundido residual por cultura familiar de bebida, estatus socioeconómico y temperamento del niño es plausible. El marco de arrepentimiento también asume que el daño infantil se mapea directamente al arrepentimiento parental. La brecha de 15 puntos debe interpretarse como una dirección de efecto, no un diferencial preciso de arrepentimiento bilateral.
