 The model was first published as a series of articles in "The American Journal of Occupational Therapy" by Kielhofner and others but later extensively developed over Kielhofner's career and disseminated in numerous books and articles.Kielhofner lectured widely and consulted regularly in the United States and abroad, particularly throughout Scandinavia, the United Kingdom, (including Scotland), Ireland, Italy, France, Germany, Spain, Portugal, Japan, Hong Kong, Israel, and Central and South America.An active network of proponents across the international occupational therapy community continues to study and evolve his model through the MOHO Clearinghouse maintained at the University of Illinois at Chicago (UIC).
