Összefoglaló szövege

Individual differences in reinforcement sensitivity are associated with substance use, with this link particularly relevant in adolescence; a developmental phase characterized by heightened reward sensitivity and that marks the onset of substance use experimentation. Despite data on pairwise associations among these variables, no comprehensive, systematic investigation of reinforcement sensitivity and adolescent substance use is available and mechanisms through which heightened reinforcement sensitivity predisposes youth to substance use remain unknown.
Aims were to examine whether (1) reinforcement sensitivity, indexed by behavioral approach (BAS) and behavioral inhibition (BIS) system sensitivity, is associated with substance use and (2) associations are mediated by positive (PA) and negative (NA) affectivity. Participants were N=71 adolescents (Mage=15.01 years, SD=.80; 44% boys).
Findings evince bivariate associations across variables, with greater reinforcement sensitivity associated with greater substance use and greater BAS and BIS associated with greater PA and NA, respectively (all rs>.3 and/or ps<.05). Results further show that the association between BAS and nicotine use (point estimate=-.28; SE=.12; 95%CIs [-.52;-.05]) and BAS and marijuana use (point estimate=-.02; SE=.01; 95%CIs [-.05;-.01]) was mediated by PA but no mediational effect of temperament on the BAS-alcohol use association was observed. The association between BIS and alcohol use was mediated by NA (point estimate=.06; SE=.02; 95%CIs [.02;.12]) but no mediational effect of temperament on the BIS-nicotine or the BIS-marijuana use association was observed. With data collection ongoing, findings will be presented on a larger sample, and clinical (e.g., for personalized prevention) and conceptual implications will be discussed at the conference.
