The purpose of this study was to examine the cross-sectional relation between reported levels of parental smoking restriction and several behavioral and cognitive variables in a sample of 757 (363 males, 394 females) adolescent smokers. Experimenters administered surveys to students in the homerooms of three Florida high schools. After controlling for student age, gender, and parental smoking status, results revealed that more restrictive parental smoking policies were significantly associated with less smoking on weekdays and weekend days, greater latency to smoking the first cigarette of the day, greater motivation to quit smoking, greater confidence in ability to quit smoking, and higher estimated risk perception regarding the health consequences of smoking. Results also revealed that 44% of adolescent smokers reported that their parents or legal guardians did not know that they smoked tobacco. These findings suggest that parental smoking restrictions may have the potential to impede adolescent progression to adult smoking behavior by reducing smoking rates and nicotine dependence, and increasing motivation to quit, self-confidence to quit, and health risk perception. Parental restrictions on smoking may present obstacles and inconveniences to adolescent smoking behavior that make smoking cessation a more attractive option.
