Choice, knowledge, and utilization of a practice theory: a national study of occupational therapists who use the model of human occupation.

Objective. To identify how therapists choose and use the Model of Human Occupation (MOHO). Method. A systematic random sample of 1,000 occupational therapists was surveyed as to whether they used MOHO in their practice. Those who were using MOHO were then sent a detailed questionnaire; 259 therapists responded to the survey questionnaire, forming a response rate of 60.2 percent. Results. A total of 80.7% of therapists indicated that they had used MOHO in their practice. A number of factors influenced therapists' choice to use MOHO. The most frequently cited factors were therapists' judgment that MOHO fit their own practice philosophy and their clients' needs. Most therapists used multiple means of learning about MOHO, and the number of means they used was related to both self-reported levels of knowledge and utilization of this model. Many therapists are also actively engaged in sharing their knowledge and utilization of this model. Conclusion. Multiple factors contribute to therapists' choice and use of MOHO. Therapists actively make a decision to use MOHO in practice and put forth substantial efforts to learn and share their knowledge of MOHO.
