Brief summary
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.
Detailed description
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.
Interventions
BEHAVIORALBreath Control - Equal Breathing Technique
The equal breathing (EB) exercise also known as square or box breathing will follow the four-part breathing cycle of inhalation, hold, exhalation, hold, repeat. Each part of the cycle will be a 4 second count repeated for 20 minutes.
BEHAVIORALGuided Mindfulness Exercise
The guided seated mindfulness (GSM) exercise will lead the participant through a 20 minute mindfulness meditation exercise using an audio recording.
BEHAVIORALControl
The control intervention will utilize a sham exercise. The participant will be asked to rest in a comfortable seated position for the duration of the 20 minute session.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effectiveness of intervention (PANAS) | Assessed at baseline, at the end of weeks 1, 2, 3, 4, 5, 6, 7 and 8 throughout intervention participation | Change in participant outcome measures (questionnaires) for all treatment arms: Change in positive and negative affect measured by PANAS - total score ranges from 10 (lower) to 50 (higher) for each of positive affect and negative affect for all treatment arms |
| Effectiveness of intervention (GAD-7) | Assessed at baseline, at the end of weeks 2, 4, 6, and 8 throughout intervention participation for duration of study | Change in participant outcome measures (questionnaires) for all treatment arms: Change in anxiety symptoms measured by GAD-7 - total score ranges from 0 (no symptoms) to 21 (severe symptoms) for all treatment arms |
| Effectiveness of intervention (RPQ) | Assessed at baseline, at the end of weeks 1, 2, 3, 4, 5, 6, 7 and 8 throughout intervention participation | Change in participant outcome measures (questionnaires) for all treatment arms: Change in post-concussion symptoms measured by RPQ - total score ranges from 0 (not experienced) to 64 (severe problem) for all treatment arms |
| Feasibility of recruitment | Start of recruitment and end of recruitment (approximately 4 months from initiation of study) | Proportion of screened individuals choosing to participate (and reasons for not participating) |
| Feasibility of completion | Start of study participation at baseline and end of study participation at completion of study (approximately 6 months from initiation of study) | Proportion of participants who drop-out prior to program completion |
| Feasibility of compliance | Start of study participation at baseline and end of study participation at completion of study (approximately 6 months from initiation of study) | Proportion of program sessions attended (and reasons for non-attendance); proportion of participants that complete surveys |
| Feasibility of delivery | Start of recruitment and end of study (approximately 6 months from initiation of study) | Investigator time-cost analysis of intervention delivery (investigator time/participant) |
| Acceptability of intervention | Assessed at conclusion of 8-week intervention participation for duration of study | Evaluated using Treatment Acceptability/Adherence Scale - individual item mean score of 10 item questionnaire each ranging from 1 (strongly disagree) to 7 (agree strongly) |
| Effectiveness of intervention (PHQ-9) | Assessed at baseline, at the end of weeks 2, 4, 6, and 8 throughout intervention participation for duration of study | Change in participant outcome measures (questionnaires) for all treatment arms: Change in depressive symptoms measured by PHQ-9 - total score ranges from 0 (no symptoms) to 27 (severe symptoms) for all treatment arms |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Concussion history data | Baseline | Participant concussion history will provide descriptive analysis of mechanism of injury, number of concussions, characteristics of current concussion injury (time since injury, hospitalization due to injury) |
| Participant demographic data | Baseline | Participant demographic data will be used to describe participant volunteers to inform sample population characteristics. |
