The present study tested the feasibility of an Internet-based method to obtain objective evidence of smoking abstinence and to deliver vouchers for evidence of abstinence. Four heavy smokers participated in this 4-week study. Twice daily, participants made video recordings of themselves providing a breath carbon monoxide (CO) sample with a Web camera. The video was sent electronically to the smoking clinic. Participants could earn vouchers for gradual reductions in breath CO during an initial shaping condition, and then for achieving abstinence (CO < or = 4 ppm). Vouchers could be exchanged for merchandise at select Internet vendors. Relative to baseline conditions, participants substantially reduced their smoke intake, and 3 achieved sustained periods of abstinence. The study suggests that an Internet-based voucher reinforcement program is a feasible method to promote abstinence from cigarette smoking. 相似文献

ABSTRACT Despite the negative health consequences associated with smoking, most smokers find it difficult to quit. This is especially true for smokers with elevated social anxiety. One factor that may play a role in maintaining smoking with elevated anxiety is false safety behavior (FSB), behaviors geared toward decreasing anxiety short-term but that maintain or increase anxiety long-term. The present study tested whether FSB explained the relation of social anxiety severity with smoking among 71 current smokers. Avoidance-related FSB was the only type of FSB related to cigarettes smoked per day (CPD) and it was robustly related to more CPD. Further, social anxiety was related to CPD indirectly via FSB-Avoidance. Findings suggest that more frequent use of avoidance behaviors to manage anxiety may maintain smoking and may partially explain the high rates of smoking among those with elevated social anxiety. Thus, FSB may be a promising target in smoking cessation interventions, especially among those with elevated social anxiety. 相似文献
