Brief summary
Persistent memory symptoms after concussion are common, and likely perpetuated by unhelpful illness beliefs and coping behaviors. Results from a pilot study suggested that traditional cognitive rehabilitation and a novel cognitive-behavioral therapy (CBT) protocol were both associated with improvements in subjective memory functioning. The present study will more definitively compare the effectiveness of these interventions for improving subjective memory functioning after concussion.
Detailed description
The primary research aims of this study are to determine whether cognitive behavioral therapy (CBT) and cognitive compensatory strategy training (CCST) improves subjective memory functioning compared to usual care, and to compare the effectiveness of CBT and CCST. This study is a multisite three-armed randomized control trial (RCT) that will randomize adults with persistent memory symptoms following concussion to CBT, CCST, or a covert waitlist condition (2:2:1). Participants will be blinded to the other arms of the study and the study hypotheses.
Interventions
Cognitive behavioral therapy (CBT) is delivered by a psychologist over 10 individual (1:1) manualized videoconference sessions. The goal of this therapy is for participants to use their memory more normally (i.e., reduce avoidance and safety behaviors) and view memory lapses as less threatening.
Cognitive compensatory strategy training (CCST), a traditional cognitive rehabilitation intervention, is delivered by a Occupational Therapist over 10 individual (1:1) manualized videoconference sessions. Participants optimize their use of current compensatory strategies and/or learn new ones suited to their needs and lifestyle. The goal is to minimize memory lapses in daily life.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Multifactorial Memory Questionnaire-Satisfaction scale | Week 20 | Measures participants' concern, satisfaction, and overall appraisal of their memory ability. Participants rate their agreement with 18 statements. Total scores range from 0 to 72, with lower total scores indicating worse subjective memory functioning. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fear-Avoidance of Memory Loss Scale | Week 1 and week 20 | Assesses fears and avoidance behaviors associated with memory decline. Participants rate 24 items on a 5-point scale, where the higher scores indicate greater memory concern and maladaptive coping. |
| Patient Global Impression of Change scale | Week 20 | Participants rate how much their memory functioning has improved or declined overall since the beginning of the study, on a single item rated on a 7-point scale where the midpoint is no change. |
| Work and Social Adjustment Scale | Week 1 and week 20 | Participants rate how much their condition interferes with their ability to carry out occupational and social activities across 5 items, on a scale from 1-7 where higher scores indicate more difficulty. |
