Parallel mediation effects by sleep on the parental warmth-problem behavior links: evidence from national probability samples of Georgian and Swiss adolescents.

Previous research has documented the importance of parenting on adolescent health and well-being; however, some of the underlying mechanisms that link the quality of parent-child relationship to health, adjustment, and well-being are not clearly understood. The current study seeks to address this gap by examining the extent to which sleep functioning mediates the effects by parental warmth on different measures of adolescent problem behaviors. Specifically, we test whether sleep functioning, operationalized by sleep quality and sleep quantity, mediates the relationship between the parental warmth and three measures of problem behaviors, namely alcohol use, illegal drug use, and deviance, in two nationally representative samples of Georgian (N = 6,992; M = 15.
