Improving Basic and Social Cognition in Veterans With Schizophrenia
Summary
Veterans with schizophrenia and schizoaffective disorder experience very high levels of disability and poor community outcome. Further improvements in community outcome for patients with these disorders will not occur simply through better control of clinical symptoms. Instead, it will be necessary to find treatments that address the key determinants of poor functional outcome. Evidence strongly suggests that basic (non-social) cognitive and social cognitive deficits are among the key determinants of functional outcome for these illnesses. The primary goal of this 2-year pilot study is to implement and validate a new remediation program for social cognition that is appropriate for veterans with schizophrenia and schizoaffective disorder.
Description
Veterans with schizophrenia and schizoaffective disorder experience very high levels of disability and poor community outcome. Further improvements in community outcome for patients with these disorders will not occur simply through better control of clinical symptoms. Instead, it will be necessary to find treatments that address the key determinants of poor functional outcome. Evidence strongly suggests that basic (non-social) cognitive and social cognitive deficits are among the key determinants of functional outcome for these illnesses. The primary goal of this 2-year pilot study is to implement and validate a new remediation program for social cognition that is appropriate for veterans with schizophrenia and schizoaffective disorder.
We plan to recruit 72 patients over the 2 years of the study from the outpatient clinics at the VA Greater Los Angeles Healthcare System (VAGLAHS). They will receive baseline assessment that includes measures of social cognition, basic cognition, electrophysiology, functional capacity, clinical symptoms, community status, and demographics / clinical history. Follow up assessments will be administered at the mid-point of training (at 6 weeks) and end of training (at 12 weeks). Each follow up assessment will include measures of basic cognition, social cognition, electrophysiology, functional capacity, and clinical symptoms. The tester administering the assessments will be blind to treatment group.
Subjects will be randomly assigned to one of four groups: 1) social cognitive training, 2) basic cognitive remediation, 3) a combined social cognitive and basic cognitive intervention, or 4) social skills training. All groups will meet in one-hour sessions held twice a week over the course of 12 weeks in small groups of 3-6. The Social Cognition Intervention (SCI) is a new 24-session, manualized intervention program specifically designed to improve emotion perception, social context processing, and theory of mind / attributional bias in veterans with schizophrenia and schizoaffective disorder. The Basic Cognitive Intervention (BCI) will involve computer-assisted training exercises. Each participant will work individually on a notebook computer. The combined intervention will cover the same content areas as the social cognitive and basic cognitive interventions, but will not go into as much detail as the separate intervention programs. The control condition will be facilitated discussion of current events. Treatment will be administered in a group format with three to six patients and a training coach.

Medical and Biotech [MESH] Definitions
Cognitive Remediation
Behavioral treatment that uses drill and practice, compensatory and adaptive strategies to facilitate improvement in targeted learning areas.
Delirium, Dementia, Amnestic, Cognitive Disorders
Cognitive disorders including delirium, dementia, and other cognitive disorders. These may be the result of substance use, trauma, or other causes.
Executive Function
A set of cognitive functions that controls complex, goal-directed thought and behavior. Executive function involves multiple domains, such as CONCEPT FORMATION, goal management, cognitive flexibility, INHIBITION control, and WORKING MEMORY. Impaired executive function is seen in a range of disorders, e.g., SCHIZOPHRENIA; and ADHD.
Recreation Therapy
The enhancement of physical, cognitive, emotional and social skills so an individual may participate in chosen activities. Recreational modalities are used in designed intervention strategies, incorporating individual's interests to make the therapy process meaningful and relevant.
Cognitive Therapy
A direct form of psychotherapy based on the interpretation of situations (cognitive structure of experiences) that determine how an individual feels and behaves. It is based on the premise that cognition, the process of acquiring knowledge and forming beliefs, is a primary determinant of mood and behavior. The therapy uses behavioral and verbal techniques to identify and correct negative thinking that is at the root of the aberrant behavior.
