In order to define the possibilities and approaches to the humanization and democratization of labour rehabilitation of mental patients, to reveal and consider individual requirements constituting each patient's personality, a study was made of the motives of attending the treatment and industrial shops (TIS) by them and preferable types of labour activities. Use was made of special formalized maps devised for the given study purposes. All the possible motives of attending TIS and preferable labour activities were registered in those maps as was an objective assessment of the output per man-hour. 221 patients were examined. The results of the examination were assessed in accordance with distribution of the patients by the clinical parameters. The hierarchy of the motives and preferences and output per man-hour depended on the patients' clinical characteristics. Still, it has been established on the whole that attending TIS, 91% were willing to work, 85% to change the environment, 70% to speed up the discharge, 65% to enhance the treatment efficacy, 45% to communicate with new people, 33% to earn money. 46% of the patients reported to work passively, under the influence of persuasions. 71% preferred performing collective work, 68% unsophisticated, 63% very simple work without any responsibility, 53% mobile, 51% sedentary, 49% physical, 32% complicated, 25% individual, 7% intellectual. Only 85% of the patients attending TIS worked. The highest productivity was recorded in patients with borderline mental disorders, the lowest in patients with actual psychotic disorders.
