Occupational therapy and obsessive-compulsive disorder.

The Model of Human Occupation, used as a frame of reference in the assessment and treatment of obsessive-compulsive disorder, helped identify how major disruptions in habituation and volition can affect a person's ability to perform and adapt in his or her environment. Careful application of this model promoted a more holistic view of John's life-style and guided me, as his occupational therapist, in creating a purposeful and meaningful treatment plan.
