Several previous studies reported that substance abusers scored siginficantly higher than controls on psychoticism and neuroticism, scale on EPQ, whereas consistent results were not found on extraversion-introversion. The present study attempted to delineate personality characteristics of substance abusers and controls' based on the Eysenck's personality dimensions of psychoticism, neuroticism and extraversion-introversion. The Korean EPQ was administered to 19 substance abusers (3 heroin addicts, 1 marijuana addict and 15 alcohol addicts) and 34 controls. Results showed that substance abusers characteristically exhibited higher scores on psychoticism, and were more introverted and less sociable than controls. On neuroticism, there was no significant difference between the two groups.
