Brief summary

Previously it was believed that most people recover from a mTBI within days to weeks following injury, However we now know that up to 50% of people can experience ongoing symptoms that can impact daily functioning for months or even years after a brain injury. Experiencing ongoing symptoms can be distressing for those affected and approaches to help people manage their symptoms can help to improve recovery. Acceptance and Commitment Therapy (ACT) is one psychological approach that may help to improve recovery, We expect that the ACT intervention will be feasible to deliver within community-based concussion services, but some modifications to its content and how it is delivered may be necessary,

Interventions

Participants randomised to the intervention arm will receive five sessions of Acceptance and Commitment Therapy. The sessions will be delivered individually, in-person by a Registered Psychologist or Intern Psychologist (working under close supervision of a Registered Psychologist). Sessions will consist of 5x 1 hour sessions covering normalcy of human suffering, difference between goals and committed action, engaging in committed action in conjunction with values, separating self from thoughts,

Participants randomised to the intervention arm will receive five sessions of Acceptance and Commitment Therapy. The sessions will be delivered individually, in-person by a Registered Psychologist or Intern Psychologist (working under close supervision of a Registered Psychologist). Sessions will consist of 5x 1 hour sessions covering normalcy of human suffering, difference between goals and committed action, engaging in committed action in conjunction with values, separating self from thoughts, use of mindfulness, understanding the part of you that notices, contacting the present moment and responding to thoughts flexibly. The five session incorporating these techniques will be held once per week. Sessions will be conducted within a Psychology Clinic at a New Zealand University or concussion service. The total duration of the intervention will be 5 hours. Attendance at each session and rates of withdrawal from the intervention will be monitored.
