This is pilot study will examine the effectiveness of a group curriculum developed from the CO-OP approach. This study has two aims, the first is to standardize the group curriculum and the second is to compare the data from the group receiving CO-OP group curriculum to the control group. Primary methods will include a standardized observation of occupational performance, an semi-structured interview measuring performance and satisfaction of occupational performance, a survey of community participation, and a focus group.

Many people affected by acquired brain injury do not return to participating in their environment. Cognition is a primary predictor of participation after stroke (Wong, Baum, Chen, Young, Heinemann, 2016). Metacognitive strategy training (MST) techniques are effective tools for increasing the independence of occupational therapy patients. The Cognitive Orientation to daily Occupational Performance (CO-OP) (Polatajko & Mandich, 2004) approach is an effective form of MST. The goal of CO-OP is to generalize and transfer skills and problem solving strategies learned in therapy to increase participants' participation in their environment. While CO-OP has proven effective in adults with executive function deficits in a one on one structure and in pediatrics in a group structure, adult day rehabilitation occupational therapists have found this intervention difficult to implement secondary to the current one on one structure favored for adults. As there is a dearth of literature on group CO-OP approaches for adults this is a novel study that provides a significant opportunity to improve outcomes for OT patients.

The primary purpose of this study has two aims. The first is to standardize the CO-OP group curriculum first created for Zera's (2018) feasibility study. The second aim is to examine initial data comparing an adult CO-OP group with a control group.

This randomized control pilot study will estimate for 22 participants, 11 for the CO-OP group and 11 for the control group, expecting 8 for each to complete the study.

Quantitative data will be collected through the Canadian Occupational Performance Measure (COPM) (Law et al., 2014) an objective measure of performance and satisfaction of participants' goals, The Assessment of Motor and Process Skills (AMPS) (Fischer, & Bray Jones 2012) an observational assessment of motor and process skills, and the Community Participation Index (CPI) (Heinemann et al., 2011) a survey that measures community participation. To collect qualitative data a focus group will be completed and field notes collected. Groups will also be video recorded to collect additional qualitative data on participant group process and group facilitator use of the CO-OP cueing hierarchy. Videos will be analyzed for themes.

Inclusion Criteria:

• Current patient in day rehabilitation admitted for rehabilitation from stroke, able to communicate sufficiently to complete the COPM, able to identify two goals on the COPM, English speaking, receiving occupational therapy services, over 18 years of age.

Exclusion Criteria:

• Not a patient in day rehabilitation, primary diagnosis other than stroke, inability to communicate sufficiently to complete the COPM, unable to identify two goals on the COPM, not English speaking, not already receiving occupational therapy services, under 18 years of age.

The principle investigator (PI) will be providing the intervention and therefore will not be blinded to the COPM of the intervention group as the COPM not only provides the objective data of the participant's' performance and satisfaction of goals but the goals themselves to be addressed within the intervention. However, the PI will not be providing the intervention of the control group, the AMPS assessments, and CPI evaluations.
