About this study
This study will evaluate the practicality (i.e. acceptability to stakeholders; outcome battery feasibility; recruitment, retention, and adherence rates) and the preliminary effect of a cognitive strategy training intervention in adults with post-concussive syndrome.
Read the detailed description
Up to 90% of known traumatic brain injuries are classified as mild, with many more injuries likely going undetected. While each of these individuals experiences somatic, cognitive, and/or affective symptoms acutely following the injury, an estimated 10-15% will continue to experience these symptoms for months up to a year post-injury. The persistence of symptoms for three months or greater is termed post-concussive syndrome (PCS) and can lead to decreases in academics, job performance, leisure, daily life activities, and routines. Traditionally, rehabilitation is either not provided to these individuals or has a specific focus on alleviating impairments (e.g. sustained attention) instead of mitigating effects on daily life function. Transfer of improvements in said impairments is known to be limited. Cognitive Orientation to daily Occupational Performance (CO-OP), a type of metacognitive strategy training, has known positive effects on activity performance outcomes in acquired brain injury (e.g. subacute and chronic stroke; moderate traumatic brain injury)1-5. CO-OP has yet to be evaluated in a sample of individuals with PCS. In sum, (1) CO-OP is an evidence-based intervention for improving activity performance, and (2) it is reasonable to hypothesize that the positive effects of CO-OP may be applied in PCS to overcome similar cognitive difficulties to improve activity performance.
The central research hypothesis is that a functionally-oriented metacognitive strategy training intervention, CO-OP, will be feasible and have a positive effect on activity performance in individuals with PCS syndrome. A single-group, prospective design with outcomes gathered pre-and post-intervention will be used (n=15) to evaluate the acceptability and feasibility of CO-OP in PCS. We will also be evaluating effect size on outcome measures of activity performance and perceptions of the functional impact of PCS symptoms.
Specific Aim 1: Determine the feasibility of CO-OP in Post-Concussive Syndrome. Hypothesis 1.1: Participants will report positive perceptions of the intervention via scores greater than 3 on the Client-Satisfaction Questionnaire. Hypothesis 1.2: The study will demonstrate acceptable recruitment, retention, and adherence rates. Hypothesis 1.3: The proposed assessment battery will be feasible (average completion time <2 hours).
Specific Aim 2: Explore the preliminary effect of CO-OP in a sample of individuals with PCS on activity performance outcomes. Hypothesis 2.1: The CO-OP group will demonstrate improvements in activity performance outcomes.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CO-OP GroupBehavioural
CO-OP focuses on learning of a global problem-solving strategy, Goal-Plan-Do-Check (GPDC), within the performance of participant-chosen goals. Use of a broadly applicable strategy and meaningful activity ensures the intervention is salient to the participant and increases likelihood of transfer. Uniquely, therapists applying CO-OP use guided discovery methods, such as asking a series of probing questions, to support participants in analyzing their own performance of a given task and generating potential solutions for improving performance. Participants become equipped with these skills through repetitive application of the GPDC process. First, participants identify a specific goal (Goal). Then, participants consider a detailed plan (Plan) for accomplishing the goal. By carrying out the plan (Do) and critically analyzing the results (Check), participants determine how the plan worked. The intervention focuses on learning GPDC with gradual withdrawal of guided discovery methods.
