ABSTRACT
The conceptual beginnings of the McMaster Model of Family Functioning (MMFF) originated at McGill University in Montreal, Canada more than 50 years ago. Under the direction of Nathan Epstein, a team of clinicians and researchers began their work in family therapy by focusing on two major areas: (1) research with nonclinical families and (2) research on the process and outcome of conducting family therapy. A nonclinical family refers to a family whose members have no diagnosed psychiatric illness. The family may or may not be healthy and may have good or poor family functioning.
