The personality disorders are defined according to the DSM-5 like “an enduring maladaptive patterns of behavior, cognition and inner experience, exhibited across many contexts and deviating markedly from those accepted by the individual's cultures. These patterns develop in adolescence and the beginning of adulthood, and are associated with significant distress or disability”. The personality disorders can be a risk factor for different processes of the psychiatric pathology like suicide. The personality disorders are classified in 3 groups according to the DSM-5:
– cluster A (strange subjects): paranoid, schizoid and schizotypal;
– cluster B (immature subjects): antisocial, bordeline, histrionic and narcissistic;
– cluster C (frightened subjects): avoidant, dependent and obsessive-compulsive.
To describe the influence of personality disorders in suicide attempts.
