Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A subset of participants, who qualify for and and desire vocational rehabilitation (VR), will receive VR from the Alabama Department of Rehabilitation Services (ADRS) in addition to CICT or BFT. ADRS VR will include career counseling, prescription of on-the-job accommodations, and guidance on return-to-work. Those in the CICT + VR group will also receive on-the-job coaching from a peer mentor for a month after completing training.
CICT, with or without VR, will involve 30 hours of training. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of gaming; the remainder will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life and improving skills essential to work; the set of the latter procedures is termed the Transfer Package. ta-VNS will administered for 10 minutes before gaming and in-lab target behavior training. To accommodate the demands of participants' other activities, training sessions will be permitted to be scheduled as tightly as every weekday over 2 weeks or as loosely as every other weekday or so over 4 weeks. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life.
BFT, with or without VR, will involve 30 hours of training following the same schedule as for CICT. Ten 3-hour in-lab, face-to-face, therapist-directed sessions will be scheduled. These sessions will feature one hour of gaming; the remainder will be committed to in-lab training on the target behaviors (healthy sleep, nutrition and relaxation habits) and the procedures designed to promote transfer of behavior change to daily life. ta-VNS will be administered for 10 minutes before gaming and in-lab target behavior training. If a family caregiver is available, they will receive training on how to best support participants in their therapeutic program. After training ends, four follow-up phone calls will be scheduled approximately one-week apart with participants to promote integration of the skills gained during training into everyday life.
Participants will be randomly assigned to the interventions. Randomization will be stratified by whether participants qualify for and desire VR from ADRS or not. If yes, participants will be randomized in equal numbers to CICT + VR or BFT + VR. If no, participants will be randomized in equal numbers to CICT or BFT.
Testing will happen one month before treatment, one day before treatment, one day afterwards, and 6-months afterwards. Outcomes measured will include cognitive processing speed, cognitive function on laboratory tests, and spontaneous performance of everyday activities with important cognitive components in daily life. Another important outcome measure will be whether or not participants were able to return back to work or had significant improvements in their work activities.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CICT
Constraint-Induced Cognitive Therapy uses in-lab training on everyday activities with important cognitive components and procedures designed to transfer improvements from the treatment setting to every day life. This will be combined with computer-based processing speed training and non-invasive vagus nerve stimulation.
Processing Speed Training
Speed of processing training involves trainer-guided practice of computer-based video "games." The games require the "player" to rapidly distinguish targets from decoys, which trains how rapidly the player processes information received through their senses.
In-lab Instrumental Activities of Daily Living Training
Participant will receive shaping on IADLS. Participants will receive training on everyday tasks with important cognitive components, in which the difficulty is increased in small steps over the course of treatment.
Transfer Package
The Transfer Package was designed to try and bridge the gap between what is trained in the lab and what the participant does outside of the treatment setting. This components includes negotiation of a behavioral contract with participants at the outset of treatment regarding the responsibilities of the participant, family caregivers, if available, and the treatment team, self-monitoring, assignment of "homework," review of homework by the trainer, and support of problem-solving by the participant.
Follow Up Phone Calls
After completing training, participants will receive four follow up phone calls in the first month of training. Each call will separated by about a week. The focus of the calls will incorporating the lessons learnt during treatment into daily life.
Trans-auricular Vagus Nerve Stimulation: High Intensity
The vagus nerve run from the brain to the external ear, throat, chest, and abdomen and controls, among other functions, the rest and relax response, which supports learning and turns down inflammatory processes. The rest and relax response can be turned on by electrically stimulating the vagus nerve. We will place electrodes on the external part of each ear and safely apply a microcurrent of at least 4 milliamps. Stimulation will administered for 10 minutes near the start and midway point of each treatment session.
CICT + VR
Constraint-Induced Cognitive Therapy plus Vocational Rehabilitation uses in-lab training on everyday activities with important cognitive components and procedures designed to transfer improvements from the treatment setting to every day life. This will be combined with computer-based processing speed training and non-invasive vagus nerve stimulation. This group will also receive vocational rehabilitation from the Alabama Department of Rehabilitation Services, such as career counseling and building important career skills.

Vocational Rehabilitation
In partnership with the Alabama Department of Rehabilitation Services (ADRS), participants who are eligible may receive vocational rehabilitation. Participants will receive typical services offered by the ADRS. These could include career counseling, guidance regarding job retention or return-to-work, and guidance regarding workplace accommodations.
Peer Mentoring
Participants who are eligible for vocational rehabilitation, and agree will also have a peer mentor, a co-worker that will be trained by our team, to reinforce strategies the participant learned during training, and to help the participant problem solve issues that may arise on the job during the first month after treatment. Peer mentors will meet with trainers during the month after treatment to make sure procedures are being followed and address any issues that may arise.
