ACTIVEAcceptance and Commitment Therapy Integrated Vestibular Rehabilitation (ACTIVE) RCT

The ACT intervention group will receive Acceptance and Commitment Therapy (ACT) + usual care rehabilitation exercises and behavioral management during four weekly in person sessions along with daily at-home activities during the 4 week treatment period. The four ACT sessions will last 60 minutes each and will include: 1) values clarification and goal setting; 2) skills training in psychological flexibility including emotional acceptance, cognitive defusion, and present moment awareness; and 3) practice engaging these skills to overcome mental obstacles to values-driven goal attainment.

The CONTROL group will receive standard of care evaluations and treatments involving a holistic multidisciplinary approach, but will exclude any ACT components. Because usual standard of care is individualized to the patient's unique functional deficits, treatments may focus on any one or more of the following: vestibular, rehabilitation, neuro-optometry, neuropsychology, physical and occupational therapy, or speech and language pathology, or general mental health interventions such as instruction regarding stress reduction. The usual care intervention will be coordinated by a primary treating clinician and additional specialty care providers as indicated by the participant's evaluation, individualized patient goals, and concomitant treatments.

Participants will receive the ACT treatment. It is comprised of three processes: Open Up, Be Present, and Do What Matters. Each of these is further sub-divided, for a total of six core processes. These processes include, but are not limited to, present moment awareness, de-fusion, and committed action. This group will also receive targeted vestibular therapy and standardized behavioral management strategies (physical activity, sleep, hydration, and nutrition prescription). Participants will also receive usual care at the discretion of each site's treating providers.

Participants will receive usual care treatment at the discretion of each site's treating providers, excluding any components associated with ACT. Because usual standard of care is individualized to the patient's unique functional deficits, treatments may focus on any one or more of the following: vestibular rehabilitation, neuro-optometry, neuropsychology, physical and occupational therapy, or speech and language pathology, or general mental health interventions.
