Overview

While most children and adolescents will recovery from concussion without complication, a sizeable minority will go on to experience persistent symptoms that last for months or even years after injury. Prolonged recovery typically results in difficulties with daily activities, such as going to school, work productivity, and familial and peer relationships. Pre-existing mental health problems, coping styles, and other psychosocial factors can hugely influence recovery following concussion. As such, our research seeks to identify and understand the psychological, social, and cognitive risk and resilience factors that affect recovery outcomes from concussion and use these discoveries to develop and evaluate accessible/scalable behavioral interventions.

Research

MBI-4-mTBI Adolescents (Mindfulness-based Intervention for mild traumatic brain injury)
Our lab recently completed a small pilot (N=10) of a mindfulness-based intervention (MBI) for adolescents following concussion in collaboration with a team at the Children’s Hospital of Eastern Ontario. We found that the mindfulness-based intervention, delivered via smartphone app, was viewed as credible and was well tolerated by patients with acute and chronic concussion symptoms. We are now planning for a multi-centre randomized controlled feasibility trial of the mindfulness-based intervention for adolescents with persistent post-concussion symptoms (N=70). Participants will be randomized to receive the mindfulness-based intervention or an active control intervention. We will assess feasibility related to recruitment methods, intervention and control credibility, adherence to the intervention, and trial retention. This feasibility trial will lay the necessary ground work for a large-scale multi-centre efficacy trial.

Digital Connections
Given the poor adherence and attrition rates associated with digital interventions, and increased interest in delivering therapy online, it is of great importance to understand how best to maximize factors that may increase patient engagement with treatment. Social presence, or the extent to which a digital encounter feels like it is occurring in-person and has a sense of human connection to it, may be relevant to therapeutic alliance and engagement in self-guided digital interventions. Using a qualitative exploratory design (N=10), we will identify the factors that may be relevant to adolescents’ experience of social presence in self-guided digital interventions and determine if these factors are important for user experience and adherence to treatment. These findings will inform design changes to our digital intervention for concussion.

ABC (Attentional Bias in Concussion)
Pain catastrophizing and avoidance of pain-related stimuli can lead to disability in patients with chronic pain conditions. Attentional bias (measured via eye-tracking) plays a role in pain-catastrophizing, offering potential understanding of mechanisms that could be targeted to improve outcomes for this group. Pain catastrophizing and avoidance behaviour similarly lead to poorer outcomes from concussion. No previous research has examined the role of attentional bias in pain catastrophizing and fear avoidance behaviour in adolescents post-concussion. We will assess whether attentional bias to symptom-related stimuli is associated with pain-catastrophizing and fear-avoidance behaviour in adolescents post-concussion.
