DeMuth reviews his three years of experience with the psychiatric problems of tuberculous patients at the Montefiore Hospital Country Sanatorium at Bedford Hills, New York. The psychiatric program in this hospital consisted essentially of a variable amount of analytically oriented brief psychotherapy. Similar psychodynamic mechanisms are visible in the case material of both tuberculous and nontuberculous patients. In the tuberculous patients themselves, the psycho-dynamics are shown to vary considerably. DeMuth concludes, as a result of his study, that there is no specific personality type but that the tuberculous infection is superimposed upon different pre-existing personalities.
