Rehabilitation psychologists help organize an array of services for people with disabilities over their lifespan. They determine the order of services such as screening, assessment of functioning levels, schooling and vocational options, family support, and ensuring ongoing rehabilitation aid and government benefits. Rehabilitation psychologists conduct psychological assessments in areas like development, adaptive behavior, intellectual ability, information processing, and behavior, and provide interventions including behavior modification, counseling to parents and families, cognitive stimulation therapy, and cognitive behavioral therapy.
