• The tendency to ascribe emotional and physical illness to overwork led to a study of 91 patients in an attempt to identify the occupational factors involved.
A variety of occupational situations was found to precipitate psychic and somatic symptoms. Eightyfour patients had difficulties traceable to interpersonal relations, and in 49 instances the trouble was disagreement with the immediate supervisor. The resultant complaints were somatic in seven patients, and nine typical cases of conversion hysteria were found. But in no case did the disturbance result in actual physical disease.
