Different Personality Profiles Between Methamphetamine Abusers with Psychotic Features and without Psychotic Features

Objectives：This study aimed to investigate personality profile differences among methamphetamine abusers admitted to Bugok National Hospital according to the presence or absence of psychotic features. Participants & Methods：Participants were 37 hospitalized male patients who met the DSM-IV criteria for methamphetamine abuse or dependence. We evaluated their psychotic symptoms using the Brief Psychiatric Rating Scale (BPRS). To measure personality traits, we used the Temperament and Character Inventory (TCI) and the NEO Five Factor Inventory (NEO-FFI). We used the independent t-test to analyze differences in inventory profiles between participants with the sole diagnosis of Methamphetamine Dependence with, or without, psychotic symptoms. Results：Compared with their non-psychotic counterparts, methamphetamine users with psychotic features showed significantly higher Novelty-Seeking and, Harm Avoidance and lower Extraversion. Conclusion：This study suggests that differences in methamphetamine abusers’ personality profiles might suggest possible vulnerability to methamphetamine-induced psychotic features. Further trials, larger and well-designed, could more accurately define differences in personality profiles between methamphetamine users with psychotic features and without psycho-tic features.
