Abstract

Background: Sensation seeking is a strong correlate of smoking among adolescents, yet the research on mediators of this association is not well established. The proposed model of the present study includes antecedent variables (sensation seeking), mediators (perceived peer smoking, outcome expectancies including negative consequences, positive reinforcement, negative reinforcement, and appetite-and-weight control), and one outcome variable (smoking cigarettes during the past 30 days).

Methods: Self-reported data obtained from Hungarian high-school students (ninth grade, N = 2,565, mean age 15.3 years, SD = 0.56) were analyzed with structural equation modeling. Before testing of the main model, the construct validity of mediators (outcome expectancy scales) was supported with confirmatory factor analysis (CFA) and structural equation modeling. The final model was tested with structural equation modeling, and the goodness-of-fit indices and the proportion of direct and indirect effects were analyzed.

Results: Our mediational model had an excellent model fit, and this study supported both the proposed sensation seeking-->positive and negative reinforcement-->smoking behavior pathways and sensation seeking-->perceived peer smoking-->positive and negative reinforcement-->smoking behavior pathways. The total indirect effect explains 76% of sensation seeking and smoking association. Results support the notion that positive and negative reinforcement expectancies mediate between sensation seeking and smoking.

Discussion: Results support the notion that perceived peer smoking, positive and negative reinforcement expectancies mediate between sensation seeking and smoking.
