[Personality disorders and abstinence from tobacco consumption in a psychological treatment to stop smoking].

The relationship between the presence of personality disorders and the effectiveness of a psychological treatment to stop smoking, measured in terms of abstinence at the end of treatment and at the 6- and 12-month follow-ups was studied. The sample was made up of 202 smokers who received Becoña's psychological treatment called Program to stop smoking . The Millon Clinical Multiaxial Inventory (MCMI-II) was used to assess personality disorders. Abstinence at the end of treatment and at the 6- and 12-month follow-ups was confirmed by a test of carbon monoxide in exhaled air. The results revealed no differences in the percentage of abstinent individuals with and without personality disorders at the end of treatment. At 6 months, the percentage of abstinent individuals was significantly higher in smokers with an antisocial personality disorder. However, the percentage of abstinent individuals was significantly lower in smokers with a dependent personality disorder at 6 and 12 months. We conclude that not all personality disorders have a negative impact either on smoking cessation or on maintaining abstinence.
