[Pathological gambling and personality disorders: a pilot-study with the MCMI-II].

In this paper, the most frequent personality disorders related to pathological gambling are described. A sample of 50 pathological gamblers, who were assessed with the MCMI-II before treatment, and of 50 normative subjects from general population with the same demographic features (age, sex and socioeconomic level) was selected. According to the results, the 40% of clinical sample (versus the 14% of normative sample) showed at least one personality disorder. The most prevalent one was the Narcissistic (32%), followed by the Antisocial and Passive-Aggressive (16% each one of them). Furthermore, the gamblers with personality disorders presented an average of 2.2 disorders and tended to be more impulsive. Likewise pathological gamblers abused of alcohol, showed a mild anxiety and were not so adapted to everyday life as much as the control group. Finally, implications of this study for clinical practice and future research in this field are commented upon.
