[Studies on the occupational maladjustment syndrome. With reference to the survey of examinations, etiological factors and treatment].

A survey of medical examinations has been made on occupational maladjustment syndrome (O.M.A.S.). We have examined and treated on 358 patients with O.M.A.S. during the past 10-15 years at two clinics; one was a company's clinic (this company has 15,000 employees) and the other was the clinic at the Dept. of Mental Health, Osaka Prefectural Institute of Public Health during the past 15 years. Discussions have been made on 150 patients whom we directly treated. Our 358 subjects having O.M.A.S. do not include those with secondary O.M.A. resulting from psychosis, depression, neurosis and physical impairment. From that reason, our subjects are categorized in a narrow sense, in a category which may be called as "adjustment disorder." The results are summarized as follows. 1. The patients with O.M.A.S. were found almost in males and most commonly found among patients in the twenties. 2. The average rate of patients with O.M.A.S. among all the patients who visited two clinics, was 4.1% at our clinic and 16.7% at the company's clinic. 3. At our clinic, the number of patients with O.M.A.S. was followed by the number of those with neurosis, schizophrenia and manic-depressive psychotic zone. This trend was also the same at the company's clinic. 4. As the cause of O.M.A.S., we found the following occupational factors; firstly, transposition by selective promotion, secondly, complication of job-quality, and thirdly, promotion to middle management position. As to personal factors, i.e. as to characteristic individual personality we found mostly rigid and serious trait, next immaturity and egotism, and timidity and nervousness. 5. The relation between the occupational and individual factors was examined from the psychodynamic point of view. From the result, O.M.A.S. was classified into 5 groups which consisted of the core group, dropout group, special job maladjustment group, transient reaction group and others. 6. In conclusion of the above mentioned data, the authors emphasize that it is important to explain and advise by the therapists not only for patients and their families, but also for their colleagues or superiors in their working place.
