Neurosis from the viewpoint of DIS (Diagnostic Interview Schedule).
We examined the relationship between clinical and DIS-Lifetime diagnoses given independently on 106 psychiatric patients clinically diagnosed as suffering from neurosis. They had many coexisting DIS diagnoses, and some of them had no DIS diagnosis. The key to the coexistence relationships in DIS diagnosis was a major depressive episode, and the subjects were classified into four types by the DIS coexistence relationships; Type I: 28 cases (26.4%) had coexisting diagnoses belonging to anxiety disorders or somatoform disorders, in addition to a major depressive episode. They were suffering from clinically severe neurosis accompanied by borderline personality disorder. Type II: 30 cases (28.3%) belonged to anxiety disorders or somatoform disorders without a major depressive episode without anxiety disorders or somatoform disorders, and had clinically depressive neurosis or depressive episode with less distortion of the personality. Type IV: 30 cases (28.3%) were other than Type I-III, and were clinically similar to symptomatic neurosis.
