PEO-P vs CMOP-E – Similarities & Differences

Many people ask what the similarities differences between PEO-P (Person-Environment-Occupation-Performance Model) and CMOP-E (Canadian Model of Occupational Performance and Engagement) are. An easy way to remember and compare them is think of this flow chart:

CMOP-E: Person Environment Occupation Fit > Occupational Performance > Occupational Engagement

PEO-P: Enablers and Barriers > Occupational Performance > Occupational Participation

Also, take a look at the two model’s diagrams on Google Images – the ring/triangle model for CMOP-E and the Venn diagrams for PEO-P.


  • Both have person, occupation, and environment.
  • They are both top-down (instead of bottom-up).
  • Both CMOP-E and PEO’s focus on intervention for “occupational performance”.


  • The individual person in CMOP-E is at the center The PEOP model is depicted as Venn diagrams, so there is “equal” importance to person, environment, and occupation in PEOP, but instead greater importance on the person in CMOP-E (individual is in the center with spirituality).
  • The intervention in how you reach occupational performance for each model differs though. With CMOP-E, the focus of intervention is on the person, occupation, environment fit between these factors. With PEO, the focus of intervention is instead on addressing enablers and barriers to each component of person, environment, or occupation.
  • With regards to the environment, and how OT is moving from the individual to the larger population, both the CMOPE and PEOP address the institutional environment.
  • Another difference is the end goal. The desired outcome of CMOP-E is occupational “Engagement”, like the E in CMOP-E, whereas the desired outcome for PEO is occupational “participation”, hence the abbreviation of PEO is now PEO dash P, for participation.
