This study investigated the psychological characteristics in patients with temporomandibular joint disorders(TMD). On MMPI's diagnostic impressions, somatization and depression were about 60%, anxiety were about 11%, normal profile were about 14%, psychotic impression and personality disorders were about 2-3%. Comparing the TMD group with exception of the normal profile and psychiatric patients who had the same diagnostic impression, we gave the result that two groups exhibited the elevation in 1, 2, 3, 7 scales in MMPI at the level of 60-65T range. On the contrary, the TMD group exhibited the marked elevation of the 4(Pd) scale in statistically significant level, but psychiatric group exhibited the tendency of the decrease in K scale. The result indicated that the TMD and psychiatric(especially the neurotic group) group had the similarity in depressive mood, pessimistic thought, high anxiety and apprehension level, somatic complaint etc., but exhibited the difference in tension level and/or aggression and ego-strength. The clinical implication, additional analyses including significant sex difference, and prospect of the further study were discussed.
