This study will assess the feasibility of a randomized control study designed to remotely deliver a breath control and guided mindfulness exercise to individuals experiencing post-concussion symptoms of anxiety or depression. Participants will be randomized into one of the study arms after they have met eligibility criteria and have given informed consent. Study arm interventions include a 20-minute paced breathing (breath control) exercise, a 20-minute guided mindfulness exercise, and a sham control arm that incorporates a minimal instruction 20-minute quiet sitting meditation exercise. The participant is asked to complete their assigned intervention daily for a period of eight weeks and to complete weekly and biweekly follow-up questionnaires. The questionnaires will include the Rivermead Post-Concussion Syndrome Questionnaire (RPQ) and the Positive Affect Negative Affect Survey Short Form (PANAS) completed weekly, the General Anxiety and Depression questionnaire (GAD-7) and the Patient Health Questionnaire (PHQ-9) completed biweekly. These questionnaires will be completed prior to a participant commencing the study (pre-test measure), at weekly intervals throughout the study (at end of week), and at the conclusion of the 8-week study (post-test measure). At the conclusion of the study participants will be asked to complete the Treatment Acceptability / Adherence Scale (TAAS), a measure used to assess the acceptability of the intervention from the point of view of the participant. All participant outcome measures, and intervention tracking questionnaires will be administered through a secure internet user-input interface.
Persistent-post-concussion symptoms (PPCS) is a condition that effects on average one in seven persons following a concussion. Anxiety and depression symptoms are experienced by over one-third of those with PPCS. These symptoms can delay recovery from a concussion. Two techniques used to treat anxiety and depression symptoms are breath control and mindfulness exercises. This 8-week feasibility study will evaluate the implementation and compliance of a remote delivered breathing and mindfulness treatment program for individuals experiencing PPCS anxiety or depression symptoms.
