Parenting and family factors: The impact of parenting styles on adolescent alcohol use: the TRAILS study

Authors: Visser L, de Winter AF, Vollebergh WA, Verhulst FC, Reijneveld SA

Aims. To investigate the influence of parenting styles (overprotection, emotional warmth, and rejection) in early adolescence on regular alcohol use in late adolescence. Methods. We analyzed data from the first three waves (mean ages: 11.09, 13.56, and 16.27 years, respectively) of a population-based prospective cohort study of 2,230 adolescents, conducted between 2001 and 2007. Adolescents reported on parental overprotection, emotional warmth, and rejection (T1). Regular alcohol use was defined as six and seven glasses or more a week for girls and boys, respectively. We further assessed family socioeconomic status, parental divorce, parental alcohol use, educational level of the adolescent, and alcohol use at baseline. Results. Parental overprotection had the strongest relationship to regular alcohol use: adolescents who perceived more parental overprotection were at increased risk of developing regular alcohol use, even after adjustment for several confounders. Rejection was not related to adolescents' alcohol use and, after adjustment for the other variables, neither was emotional warmth. Conclusion. Overprotective parenting is a determinant of future regular adolescent alcohol use and therefore health professionals should pay particular attention to those adolescents who have overprotective parents. The role of adolescent characteristics in the relationship between overprotection and alcohol use deserves further study.

Parenting and family factors: The dopamine receptor D4 and familial loading interact with perceived parenting in predicting externalizing behavior problems in early adolescence. The TRAILS study

Authors: Marsman R., Oldehinkel A.J., Ormel J., Buitelaar J.K.

Although externalizing behavior problems show in general a high stability over time, the course of externalizing behavior problems may vary from individual to individual. Our main goal was to investigate the predictive role of parenting on externalizing behavior problems. In addition, we investigated the potential moderating role of gender and genetic risk (operationalized as familial loading of externalizing behavior problems (FLE), and presence or absence of the DRD4 7-repeat and 4-repeat allele, respectively). Perceived parenting (rejection, emotional warmth, and overprotection) and FLE were assessed in a population-based sample of 1768 10- to 12-year-old adolescents. Externalizing behavior problems were assessed at the same age and 212 years later by parent report (CBCL) and self-report (YSR). DNA was extracted from blood samples. Parental emotional warmth predicted lower, and parental overprotection and rejection predicted higher levels of externalizing behavior problems. Whereas none of the parenting factors interacted with gender and the DRD4 7-repeat allele, we did find interaction effects with FLE and the DRD4 4-repeat allele. That is, the predictive effect of parental rejection was only observed in adolescents from low FLE families and the predictive effect of parental overprotection was stronger in adolescents not carrying the DRD4 4-repeat allele.
