Evaluation of a Visual Remediation Intervention for Schizophrenia

Schizophrenia is a severe psychiatric condition that is associated with significant distress and disability. In addition to cognitive difficulties in domains such as attention, memory, and problem-solving, individuals with schizophrenia can experience visual-processing abnormalities, including impairments in visual acuity, low-contrast stimulus detection, and perceptual organization (i.e., perceiving visual information in an organized "perceptual whole"). These visual impairments are clinically significant, with research indicating that specific visual-processing alterations are significantly related to poorer performance on higher-level cognitive tasks, impaired facial emotion recognition, impaired reading ability, and worse functional outcomes. Despite such findings, very few studies have evaluated the therapeutic potential of interventions that are specifically designed to improve visual processing ("visual remediation") for individuals with schizophrenia. Thus the aim of this study is to evaluate the efficacy of a computerized visual perceptual training program that targets low- and mid-level visual processes to improve visual, cognitive, and emotion-recognition functions in outpatients with schizophrenia through a small randomized controlled trial. The investigators will recruit up to 40 individuals with schizophrenia or schizoaffective disorder who are receiving treatment in Rutgers University Behavioral Health Care (UBHC) Partial Hospital Program; half will be randomized to receive the computerized visual training, which will be delivered in small groups over a period of 12-14 weeks. The specific aims of this study are to collect preliminary data on: 1) the feasibility of participant recruitment and retention, and tolerability of the treatment components of the study; and 2) the efficacy of computerized visual training (VT) to improve low- and mid-level visual processes, and higher-level cognitive and social-cognitive performance.
