 This study integrates cognitive rehabilitation in residential care for homeless Veterans. In a 15-week randomized controlled trial, the investigators will compare an evidence-based, 10-week Compensatory Cognitive Training CCT intervention to an education control condition for homeless Veterans with cognitive impairment. CCT aims to improve real-world cognitive performance by teaching strategies to improve prospective memory remembering to do things, attention, learningmemory, and executive functioning. Strategies to reduce stress and improve sleep are also included. CCT has been shown to improve cognition, functional capacity, neurobehavioral symptom severity, and quality of life in individuals with cognitive impairment associated with psychiatric illness and in Veterans with traumatic brain injury TBI. During the trial, assessments will be administered at baseline, 5 weeks, 10 weeks, and 15 weeks, and monthly follow-up phone calls will assess housing and employmenteducation status for one year following program discharge. The investigators expect CCT-associated improvements in cognition and functional skills co-primary outcomes and generalization to reduced levels of disability, along with improved community reintegration outcomes better housing stability, participation in work or school, and healthcare appointment attendance. If effective, the CCT intervention could be exported to the 80 residential VA programs serving homeless Veterans. The investigators thus propose the following aims:
