title: Subtypes of smokers who attend psychological treatment in order to stop smoking.
abstract: The aim of this study is to identify subtypes of smokers who attended psychological treatment during the period 2006-2008 for smoking cessation from a sample of current smokers (N = 202) from Galicia, Spain. Eight instruments were used for data collection. Demographic variables, smoking variables, and psychopathological characteristics were clustered to establish typologies of smokers. A two-phase cluster analysis identified two subtypes of smokers (141 in Cluster 1 and 61 in Cluster 2). Those in Cluster 2 were younger, and had made an attempt to quit in the last year. They presented higher levels of nicotine dependence and psychopathology than those in Cluster 1. Differences in nicotine withdrawal syndrome, cigarette consumption at the end of the treatment, and adherence to the treatment were significant across the two clusters.
