History of the CO-OP Approach
CO-OP was initially developed for children with developmental coordination disorder (DCD), a condition that makes it challenging to learn new motor skills. CO-OP has several important components. The Approach was developed as an alternative to the traditional treatment approaches of the day. Traditional approaches to treatment for children with motor-based problems focused on impairment-based goals. Therapy consisted of identifying impairments in underlying components and treating those performance components. For example, if Anna, a child with DCD, has a goal of improving her printing, a therapist might determine that Anna has poor fine motor skills and set “improving fine motor skills” as a treatment goal, believing that improving fine motor skills will lead to improvements in printing. Similarly, if Jim, after having a stroke, has a goal of walking confidently in a busy shopping mall, the therapist might determine that Jim’s problem with walking is his poor balance and set a treatment goal “improve balance”. These treatment goals were based on the idea that performance would generally improve for activities once the impaired underlying components got better.

The CO-OP developers, aware that research had shown that the traditional approaches did not usually lead to improved performance sought an alternative. An early study by Polatajko and Colleagues showed that direct teaching could lead to improved performance in children with DCD. This suggested that using a learning approach might be more successful than traditional impairment reduction approaches. Using this perspective, the CO-OP developers drew on ideas from Donald Meichenbaum, who was using Goal-Plan-Do-Check as a strategy to improve performance through verbal self-instruction, to inform the creation of a research programme designed to develop a new performance-based, problem-solving approach. The new approach was initially called Verbal Self Guidance, but as more was learned and components were added, it became CO-OP.
After a number of smaller studies indicated that CO-OP had potential as an intervention to improve performance, a randomized control trial was undertaken comparing CO-OP to traditional therapy in children with DCD. The RCT, published in 2001, demonstrated a significant effect of CO-OP in skill performance. Research on the CO-OP Approach, which is ongoing, has shown that the problem solving skills learned during CO-OP could be applied to a variety of activities, with different therapists working in in different environments, with different client groups.
Because of CO-OP’s success, two books have been published on the Approach. The first (Polatajko and Mandich, 2004) focused primarily on children with DCD, details the theoretical foundations and key features of the Approach. The second (Dawson, McEwen, Polatajko, xxxx) adopts a lifespan approach and describes the use of the Approach with a variety of other populations, including children with Asperger’s syndrome and cerebral palsy and adults with traumatic brain injury and stroke. The book also describes the application of the Approach in alternative delivery methods, including groups.

Core Principles


Who can benefit from CO-OP?
CO-OP was initially developed for children with developmental coordination disorder (DCD), but since has been demonstrated to be effective with several other populations:Acquired brain injury
· Autism Spectrum Disorder
· Cerebral palsy
· Developmental delays
· Dystonia
· Parkinson’s Disease
· Stroke
· Older adults with self-identified cognitive impairment.
CO-OP is a versatile approach with multiple applications across ages and diagnoses. Despite its versatility, it is recommended that clients have certain pre-requisite skills. These are as follows:
- The client must be able to select occupations or activities that they would like to learn or for which they would like to improve their current performance level. The client identifies these occupations through an interview using the Canadian Occupational Performance Measure (COPM).
- The client must have sufficient language fluency in order to discuss their performance with the therapist.
- The client must have sufficient cognitive ability to benefit from CO-OP’s problem-solving approach. Research has demonstrated that clients with cognitive impairments can benefit from CO-OP, so sufficient cognitive ability relates to the ability to learn and remember from session to session.
Clinical Objectives
Skill acquisition | Skill acquisition is the primary objective of CO-OP. Clients acquire the skills they select as personally meaningful. |
Cognitive strategy use | Clients learn how to use cognitive strategies to solve performance problems. They learn to use the global cognitive strategy, Goal-Plan-Do-Check, as a problem-solving framework. Within the Plan phase, they learn to analyse their performance and discover domain-specific strategies that are specific to that individual and the particular skill and context. |
Generalization | Clients are able to do the occupations or activities they learned in multiple environments, rather than just in therapy. For example, if Anna identifies in therapy that she needs to stabilize a piece of paper to improve her printing, she will also be able to do this at home and in her classroom. |
Transfer | Skills learned in CO-OP, including both the occupations and using the global cognitive strategy, are transferred to facilitate the learning of new skills as needed. For example, if Jim learned to use Goal-Plan-Do-Check to learn to walk in the mall, he may go on to use this problem solving strategy to learn to cut his lawn, or even for a very different skill, such as playing guitar. |

Key Feature 3: Cognitive Strategy Use
Global Strategy | Domain Specific Strategies |
A global cognitive strategy, also known as a metacognitive strategy, is a structured framework that can be used in any situation and includes an evaluation component. In CO-OP, the global cognitive strategy is Goal-Plan-Do-Check. Clients are taught to identify a Goal, Develop a Plan, Do the plan, and Check to see if the Plan worked. | Domain specific strategies are specific to an individual, the skill being learned, and the context. Examples include body position strategies (Jim lifts his knee high when walking), attention to doing (Anna focuses on the lines when she is printing), task specification (Anna notices the long stick on the letter “b” is on the left side), task modification (to reduce fatigue, Jim cuts half the lawn one day and the other half the next), and verbal motor mnemonics (Anna thinks the letter “s” looks like a snake). |





Key Feature 4: Guided Discovery
- One thing at a time
- Ask, don’t tell.
- Coach, don’t adjust
- Make it obvious
Key Feature 5: Enabling Principles
- Make it fun/make it engaging. For children and adults alike, learning is more likely to occur if the process is enjoyable. For children, this may involve using games, fun challenges, or silliness. For adults, it involves encouraging their self-motivated and self-directed exploration of problem-solving solutions to their performance challenges.
-
Promote learning. Use established teaching techniques, including:
- Reinforcement
- Direct teaching
- Modeling
- Shaping
- Prompting
- Fading
- Chaining
- Work towards independence. Similar to how learning is promoted by removing prompts, the therapist should remove their verbal and physical support as the skill improves.
- Promote generalization and transfer. The therapist seeks opportunities to directly promote generalization and transfer, such as explicitly asking the client how their strategy will work outside the practice setting and what other skills it can be used with.
Key Feature 6: Parent or significant other involvement
Parents and significant other involvement is an important component in skill acquisition and generalization and transfer. The therapist should provide education to parents/significant others about CO-OP and its underlying principles. Parents and significant others are encouraged to participate in goal setting and attend at least three sessions to observe how CO-OP is carried out.Key Feature 7: Intervention format
While CO-OP’s intervention format can undergo some alterations to best meet the needs of certain populations or delivery methods, the overall structure remains the same:Pre Intervention | Three goals are established and baseline performance on goals is evaluated. |
Intervention | In the first session, the global cognitive strategy (Goal-Plan-Do-Check) is taught. In subsequent sessions, the global strategy is used together with DPA, guided discovery, and enabling principles to help the client discover domain-specific strategies to overcome performance issues and acquire skills. In “traditional” CO-OP, there are 10 one-on-one intervention sessions of approximately 45-60 minutes; adaptations have included more or less sessions, group delivery, and telehealth delivery. |
Homework | Assigned in all or most sessions to encourage the generalization and transfer of skills learned in the session |
Post Intervention | Re-evaluate performance on the three goals. |
