Associations between sleep habits and different impulsivity facets in adolescence

Sleep patterns change during adolescence due to physiological maturation and psychosocial factors, leading to progressively higher eveningness, sleep deprivation and social jetlag (SJL). These sleep changes are associated with impulsivity, a common behavioral trait in adolescence which can make those with developmental disabilities more vulnerable to behavioral, cognitive and clinical difficulties. However, it is unclear which aspects of sleep and what types of impulsivity are involved.

To investigate the relationships between sleep/circadian variables and self-reported impulsivity.

Three sleep/circadian variables (time in bed on weekdays, eveningness and SJL) and five dissociable facets of self-reported impulsivity (UPPS-P scale) were answered by 389 healthy 9-17-year-olds (225 girls).

A significant (but small) association between eveningness and a multivariate composed of the five facets of impulsivity (5 % of variance explained) was found and negative urgency was the main driver (4 %) of this relationship.

Typically developing adolescents with high eveningness traits display slight difficulty controlling their behavior when in a state of negative affect. This finding deserves an in-depth investigation in youth with neurodevelopmental disabilities, who are more prone to presenting sleep/circadian changes, externalizing problems like impulsiveness and internalizing one such as mood alterations.
