Objective To evaluate, before undertaking a larger trial, feasibility of the study processes to determine the effectiveness of occupation-based strategy training for producing changes on trained real-world behaviors, and to determine whether far transfer of training effects to measures of real-world impact, including participation in everyday life, could be achieved. Design Partially randomized controlled trial with pre- and postintervention assessments done by assessors masked to the treatment arm. Setting Testing occurred at a research institute, interventions at participants' homes. Participants People (N=13) with chronic traumatic brain injury (TBI), 7 in the experimental group (mean age, 42.6y; mean time post-TBI, 9.8y; 4 men) and 6 in the control arm (mean age, 40.5y; mean time post-TBI, 10.8y; 3 men), were assessed immediately before and after the intervention phase. Intervention Occupation-based strategy training, an adapted version of the Cognitive Orientation to daily Occupational Performance (CO-OP), was provided in two 1-hour sessions per week for 10 weeks. Main Outcome Measures Canadian Occupational Performance Measure, Dysexecutive Questionnaire, Mayo-Portland Adaptability Inventory-4 Participation Index, and Assessment of Motor and Process Skills. Results The study processes (testing and intervention) were acceptable to all participants. Evidence of far transfer was found as the experimental group improved significantly more than the control group on performance and satisfaction with performance ratings on untrained goals (P<.05), and reported increased levels of participation (P<.01). Conclusions Findings must be interpreted with caution since the sample is small and comparisons are made with a no-treatment control. Nevertheless, they suggest that the training is feasible and a larger trial warranted.
