Eleanor Clarke Slagle (1870-1942) is considered to be the “mother” of occupational therapy. Slagle, who was one of the founding members of the National Society for the Promotion of Occupational Therapy (NSPOT), proposed habit training as a primary occupational therapy model of treatment. Based on the philosophy that engagement in meaningful routines shape a person's wellbeing, habit training focused on creating structure and balance between work, rest and leisure. Although habit training was initially developed to treat individuals with mental health conditions, its basic tenets are apparent in modern treatment models that are utilized across a wide scope of client populations.
