Growing up, getting drunk : development and prevention of adolescent alcohol use

Alcohol use is the main cause of disease and death among adolescents in Europe. This is the first Dutch research that studied the effects of intensified enforcement of the age limits for alcohol use (formal control) and of making alcohol less available to adolescents via the social environment (informal control via parents and schools). Increasing the formal and informal control turned out to reduce the risk of intoxication in drinking adolescents. Given the upcoming decentralization of enforcement to municipalities, this means that the Dutch community must actively increase formal and informal control to reduce intoxication among adolescents

Are the effects of early pubertal timing on the initiation of weekly alcohol use mediated by peers and/or parents? A longitudinal study

Item does not contain fulltextWe investigated whether the link between early pubertal timing and initiation of weekly alcohol use is mediated by changes in perceived parental alcohol-specific rule setting and changes in perceived proportion of drinkers in the peer group. Longitudinal data including 3 annual waves were used to estimate the hazard for adolescents to initiate drinking alcohol using Cox proportional hazard structural equation models in 1,286 Dutch adolescents (50.2% boys) 13–14 years old at baseline in 2008. Early pubertal timing increased the risk to initiate weekly alcohol use. However, this risk was entirely mediated by a large increase in the perceived proportion of drinkers in the peer group and a large decrease in the frequency of perceived alcohol-specific rules for early pubertal timers within a period of 1 year. There is no direct risk for early pubertal timers to initiate weekly drinking per se but an indirect one via changes in their social environments, that is, a large increase in the perceived proportion of drinkers in their peer group and parents becoming more lenient in their alcohol-specific rule setting. It is important to motivate parents not to relax their alcohol-specific rule setting over time, particularly parents of early pubertal timers.9 p

Drinking motives and drinking behavior over time: A full cross-lagged panel study among adults

Item does not contain fulltextDrinking motives are among the most proximal factors for drinking behavior and serve as a mechanism through which more distal factors are mediated. However, it is less clear whether drinking motives are precursors of drinking or, in contrast, shaped by previous drinking experiences (reciprocal effects), or both. Moreover, in adults it is unclear whether drinking motives, usually shaped in adolescence, influence each other over time. In this longitudinal study (N = 2440, 47% women, average age 53 years), drinking motives and drinking behavior (i.e., number of drinks on the heaviest drinking day and number of drinking days; both during the past week) were assessed at 2 time points, separated by 3 months. Full cross-lagged regression models revealed that drinking motives were positively associated with drinking behavior over time and that drinking motives are shaped by the number of drinking days (i.e., reciprocal effects). Furthermore, coping and enhancement motives, as well as social and conformity motives, positively reinforced each other. Moreover, social motives were positively associated with enhancement motives over time. In conclusion, drinking motives influence each other over a 3-month period in adulthood and predict drinking behavior over time, making them important candidates for prevention efforts. Drinking motives are likely to be modifiable and might be used to stimulate drinking decrease.5 p

Preventing adolescent a0lcohol use: Effects of a two-year quasi-experimental community intervention intensifying formal and informal control

Contains fulltext : 126421.pdf (publisher's version ) (Closed access)Purpose: To determine the effect on adolescent alcohol use of a community intervention combining intensified formal control (restricting retail supply) and informal control (restricting social supply). Intervention effects on intermediate intervention goals were investigated. Analyses for different age groups were performed. Methods: A longitudinal quasi-experimental design (baseline at 2008, plus two yearly post-measurements) was used, including one intervention and one matched-comparison community in The Netherlands. We assessed outcomes by observing 1,368 Dutch adolescents aged 13-15 years at baseline. Main dependent variables were weekly drinking status and progression into drunkenness among weekly drinkers. Additional dependent variables were formal control intermediate intervention goals (frequency of alcohol purchases and perceived ease of purchasing alcohol) and informal control intermediate intervention goals (frequency of alcohol-specific rules and parental alcohol supply). Results: Survival analyses showed no significant reduction in the risk of drinking weekly for adolescents in the intervention region; however, the risk of progressing into drunkenness was reduced by 15% (p = .04) for adolescents drinking weekly. No intervention effects on the intermediate intervention goals were found among 14- and 15-year-olds. The intervention had a positive effect on two of four intermediate intervention goals (i.e., parental alcohol supply and alcohol-specific rules) among 13-year-olds. Conclusions: A combined formal and informal community intervention package is associated with a reduced risk of progressing into drunkenness among drinking adolescents. Interventions focusing on discouraging drinking below a certain age might cause a greater increase in the frequency of purchasing alcohol once reaching this age.7 p

The Effect of Pubertal and Psychosocial Timing on Adolescents' Alcohol Use: What Role Does Alcohol-Specific Parenting Play?

In scientific literature, early pubertal timing emerges as a risk factor of adolescents' drinking, whereas alcohol-specific rules (the degree to which parents permit their children to consume alcohol in various situations) showed to protect against adolescents' drinking. This study investigated whether alcohol-specific rules mediate and/or moderate the effect that early pubertal and psychosocial timing (personal, relational, socio-institutional) has on adolescents' alcohol use. Mediation and moderation models were tested conducting ordinal logistic structural equation modeling in a cross-sectional sample of 1,893 Dutch adolescents (49% males), aged 13-15 years. Findings showed that early pubertal, relational and socio-institutional timers were at greater risk to initiate alcohol use and for heavy episodic drinking. Alcohol-specific rules more often mediated, rather than moderated, the effect of early timing on alcohol use. Alcohol-specific rules are mostly relaxed when adolescents mature, rather than reinforced, indicating that parents partly facilitate adolescents' drinking

Effects of a natural community intervention intensifying alcohol law enforcement combined with a restrictive alcohol policy on adolescent alcohol use

Item does not contain fulltextPurpose Determining whether intensified inspections on alcohol retailers, combined with a policy withdrawing liquor licenses if retailers are fined twice per annum, is effective in reducing adolescents' odds to initiate weekly drinking and drunkenness. Causal pathways by which the intervention was assumed to work were tested. Methods A longitudinal (2008, 2009, and 2010) quasi-experimental comparison group design including two Dutch communities, one intervention and one comparison, was used. Outcomes were assessed by following a cohort of 1,327 adolescents (aged 13–15 years at baseline). Results The intervention resulted in increased retail inspections but only seven sanctions and no repeated sanctions in 1 year. The intervention did not reduce adolescents' odds to initiate weekly drinking. Weekly drinking adolescents in the intervention community were at reduced risk to initiate drunkenness. This effect was not mediated by smaller increases in the frequency of adolescents' alcohol purchases or their perceived ease of purchasing alcohol. Conclusions Intensified enforcement was effective in preventing adolescent drunkenness. No mediating causal pathways were detected. Effectiveness of enforcement could be increased by adopting enforcement methods with a high likelihood of apprehension, increasing social support for restrictive measures, and mobilizing the community to be more outspoken against adolescent (heavy) drinking.8 p
