Purpose

This study will compare two approaches to cognitive rehabilitation in adults with stroke with persistent, mild to moderate, cognitive impairment. Both approaches will feature a web-based computer "game" that trains cognitive processing speed, i.e., how quickly individuals process information that they receive through their senses. This training is termed Speed of Processing Training (SOPT). One approach will add (A) in-lab training on everyday activities with important cognitive components and (B) procedures designed to transfer improvements in cognition from the treatment setting to everyday life. This approach is termed Constraint-Induced Cognitive Therapy (CICT). The other approach will add (A) in-lab training on relaxation, healthy nutrition, and healthy sleep and (B) procedures designed to promote integration of these lifestyle changes into everyday life. This approach is termed Brain Fitness-Heath Education Lifestyle Program (BF-HELP). Both CICT and BF-HELP will involve 35 hours of training. Ten 1-hour sessions of SOPT will be scheduled in the home with training conducted independently by participants. Ten 2.5 hours of in-lab, face-to-face, therapist directed sessions will be scheduled. These sessions will feature a brief period of SOPT; the bulk of the sessions will be committed to in-lab training on the target behaviors and the procedures designed to promote transfer of therapeutic gains to daily life; The set of the latter procedures is termed the Transfer Package. 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. Family caregivers in both groups will also receive training on how to best support participants in their therapeutic program. The study will also test if there is an advantage to placing follow-up phone calls after treatment ends. The purpose of the calls will be to support transition of any behavioral changes achieved during treatment into everyday life on a long-term basis. Participants will be randomly assigned to the interventions. Testing will happen one month before treatment, one day before treatment, one day afterwards, and 6- and 12-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.

Intervention Model Description
Half of the participants will receive CICT, which consists of SOPT, IADL training in the lab, and a Transfer Package targeting IADL performance outside it. The other half will receive BF-HELP, which consists of SOPT, in-lab training on relaxation, nutrition, and sleep hygiene, and a Transfer Package targeting implementation of these lifestyle changes outside it. Half of the CICT group will receive 15 follow-up phone calls over the course of one year. The other CICT participants will receive none. The same will apply to the BF-HELP group. The phone calls will support integration of the behavioral changes targeted during treatment to everyday life afterwards. For all participants, outcome testing will take place one month before treatment (Baseline 1), one day before treatment (Baseline 2 aka Pre-treatment), one day afterwards (Post-treatment), 6-months afterwards (6-month Follow-up), and 12-months afterwards (12-month follow-up). Randomization will take place after Baseline 2.

Experimental
CICT with Follow-up Phone Calls 		Participants in this group will receive 35 hours of training. Ten 1-hour sessions of SOPT will be scheduled in the home with training conducted independently by participants. Ten 2.5 hours of in-lab, face-to-face, therapist directed sessions will be scheduled. These sessions will feature a brief period of SOPT; the bulk of the sessions will be committed to (A) shaping on IADL and (B) the Cognitive Transfer Package. Training sessions will be permitted to be scheduled over 2-4 weeks. Family caregivers will receive training on how to best support participants in their therapeutic program. After treatment ends, four phone calls will be placed once-a-week for four weeks, then once-a-month for 11 months. The follow-up calls will target transition of any changes achieved during treatment into everyday life on a long-term basis.
  • Behavioral: Speed of Processing Training
    This training component targets cognitive processing speed, i.e., how quickly individuals process information that they receive through their senses. Cognitive processing speed is thought to be a basic capacity of the brain that underlies several other cognitive functions. Training is implemented using a web-based computer "game", in which participants are required to fixate on a target at the center of the screen and identify targets in the periphery. The game is made progressively more difficult, in small increments, as participants gain mastery by increasing the speed at which targets are presented and increasing the number of distractors.
    Other names:
    • SOPT
  • Behavioral: Instrumental Activities of Daily Living In-lab Training
    The training component is thought to bridge SOPT training, which targets a basic cognitive capacity, and IADL performance in daily life. This training component will involve repeated trials in which participants will practice carrying out simulated IADL tasks in the lab under the supervision of the trainer. The training will follow shaping principles, i.e., task requirements will be made progressively more challenging, in small increments, as participants gain mastery. Frequent, positive feedback will be provided.
    Other names:
    • IADL In-lab Training
  • Behavioral: Cognitive Transfer Packagke
    This training component is designed to transfer improvements in cognition from the treatment setting to everyday life. Elements of this package include negotiating a behavioral contract about the roles of the participant and family caregiver in the treatment, monitoring behavior outside the lab, and assigning performance of IADL as homework.
  • Behavioral: Family Caregiver Coaching
    One or more family members of the participant will receive coaching on how to best support the participant in carrying out the in-home components of the intervention.
  • Behavioral: Follow-up Phone Calls
    After treatment ends, four phone calls will be placed once-a-week for four weeks, then once-a-month for 11 months. The follow-up calls will target transition of any changes achieved during treatment into everyday life on a long-term basis after.
