OBJECTIVE: To evaluate the personality and psychosocial status of adult malocclusion patients through the Eysenck Personality Questionnaire (EPQ) and the Symptom Checklist 90 (SCL-90). METHODS: The EPQ and the SCL-90 were administered to 348 adult respondents with Angle's Class I, II, III malocclusion and normal occlusion. Personality and psychosocial traits were analyzed and compared among the groups. RESULTS: Patients in Angle's Class I, II and III groups scored lower on the EPQ-E and higher on the EPQ-N than those in the normal occlusion group, whereas patients in the Class II group scored higher on the EPQ-P. The mean scores of Class I, II and III groups were significantly higher than those of the normal group on somatization, obsessive-compulsiveness, interpersonal sensitivity, depression, anxiety, and paranoid ideation. All SCL-90 scores were significantly positively correlated with EPQ-N. Psychoticism and neuroticism scores of female respondents were higher than those of male respondents. The impact of education was greatest on the EPQ-P and the EPQ-E of adult personality, whereas the impact of deformity was greatest on the EPQ-N of adult personality. CONCLUSIONS: Personality and psychosocial status show differences in adult patients with Class I, II, III malocclusion and normal occlusion and can be influenced by gender, deformity, age and education.
