The WORLD HEALTH ORGANIZATION in a report on Mental Health stated: in its effect on productivity, a recent investigation of the United Kingdom Medical Research Council demonstrated that psychoneurosis in an industrial community caused losses rather greater than those produced by the common cold. Very little is known of the effect of the mental health factor in rural and underdeveloped communities. The first great need is to gather information. This WHO proposes to do with the aid of the recently established World Federation for Mental Health by sending investigation teams to rural and industrial communities, as well as a special team to a selected university to investigate mental hygiene of students.
