Abstract

Parental knowledge about adolescents' whereabouts and activities remains one of the strongest predictors of reduced adolescent substance use. A recent study found that across middle childhood and adolescence, parental knowledge is characterized by fluctuations on a year-to-year basis, termed lability, even more-so than by linear trends, and that lability too is a predictor of adolescent substance use (Lippold et al., Dev. Psychol. 17, 274-283, 2016). The present study replicates Lippold et al. (Dev. Psychol. 17, 274-283, 2016) by quantifying developmental change and lability in parental knowledge across adolescence and examining associations with drinking, smoking, and other drug use later in adolescence, and extends the study by examining the sources of knowledge: child disclosure, parental solicitation, and parental control, separately. Using a community-based sample of 1023 youth in the Northeastern region of the USA, all three sources of knowledge were characterized by developmental change and lability. In general, higher levels and steeper developmental declines in knowledge were associated with substance use outcomes.

FINDINGS for child disclosure replicated the prior findings: increased lability of child disclosure predicted substance use. Unexpectedly, decreased lability of parental solicitation and control was associated with worse substance use outcomes.

FINDINGS suggest different mechanisms by which lability in child- and parent-driven cultivation of knowledge is associated with substance use. If replicated in studies that address causality, these mechanisms could be leveraged for prevention/intervention efforts. For example, increasing the consistency of child disclosure may help prevent substance use, but teaching parents to be more responsive to time-specific challenges with adolescents may be more effective than increasing the consistency of parents' knowledge-building parenting behaviors.
