The present study examined
two measures of sympathetic nervous system (SNS) activity as moderators of the
indirect path from permissive parenting to deviant peer affiliations to
delinquency among a community sample of adolescents.
Participants included 252
adolescents (M = 15.79 years; 53 % boys; 66 % European American,
34 % African American). A multi-method design was employed to address the
research questions. Two indicators of SNS reactivity, skin conductance level
reactivity (SCLR) and cardiac pre-ejection period reactivity (PEPR) were
examined. SNS activity was measured during a baseline period and a
problem-solving task (star-tracing); reactivity was computed as the difference
between the task and baseline periods. Adolescents reported on permissive
parenting, deviant peer affiliations, externalizing behaviors, and substance
use (alcohol, marijuana).
Analyses revealed indirect effects between permissive
parenting and delinquency via affiliation with deviant peers. Additionally,
links between permissive parenting to affiliation with deviant peers and
affiliation with deviant peers to delinquency was moderated by SNS reactivity.
Less SNS reactivity (less PEPR and/or less SCLR) were risk factors for
externalizing problems and alcohol use.
Findings highlight the moderating role
of SNS reactivity in parenting and peer pathways that may contribute to
adolescent delinquency and point to possibilities of targeted interventions for
vulnerable youth.
