Predictors of Adolescent
Smoking Cessation and Smoking Reduction
Haug S, Schaub MP, Schmid H.
This study investigated the processes of change, demographic, health- and
smoking-related predictors of both smoking cessation and smoking reduction in
adolescents. METHODS: Data were drawn from a sample of 755 adolescent smokers
who participated in a study testing the efficacy of a text messaging-based intervention
for smoking cessation. Demographic, health- and smoking-related variables were
assessed at baseline. Five processes of smoking cessation, derived from the
Transtheoretical Model and the Social Cognitive Theory, as well as outcome
measures were assessed at 6-month follow up. Univariate and multivariate
regression analyses were conducted to identify baseline and process variables
to predict smoking abstinence and smoking reduction. RESULTS: Male gender
(OR=0.43, p<.01), lower alcohol consumption (OR=0.90, p=.05) and a lower
number of cigarettes smoked per day at baseline (OR=0.87, p<.01) predicted
smoking abstinence. Baseline physical activity predicted smoking reduction
(OR=1.04, p=.03). None of the examined process variables significantly predicted
smoking abstinence. The process variable "counter-conditioning"
predicted smoking reduction (OR=1.46, p=.03). CONCLUSIONS: Baseline predictors
of smoking cessation differ from predictors of smoking reduction.
Counter-conditioning might be an important element in adolescent smoking
cessation interventions.
