The effects of visual remediation intervention in patients with schizophrenia: an exploratory randomized controlled trial.

Abstract

Objective: Previous studies have identified visual perception and functional impairments in individuals with schizophrenia, particularly in areas such as contour integration and contrast sensitivity. These deficits can significantly impact daily functioning and social interactions. This study aims to investigate the impact of a visual remediation intervention (VRI) on visual perception deficits, specifically contour integration and contrast sensitivity, while also assessing its effects on social cognition, visual attention, and disease symptoms.

Methods: Forty schizophrenia patients were randomly assigned to a VRI group or control group (treatment as usual). The VRI group completed 30 sessions of the 'Sightseeing' program over 10 weeks. Pre- and post-treatment assessments included measures of social cognition, visual attention, psychopathology, contour integration, and contrast sensitivity.

Results: Following intervention, the VRI group showed significant improvements in contrast sensitivity, social cognition, visual attention, and contour integration tasks, along with reduced disease symptoms.

Conclusions: The 'Sightseeing' VRI program demonstrated beneficial effects across multiple domains in schizophrenia patients. These findings suggest potential implications for future therapeutic interventions. However, it should be noted that the control group did not receive an intervention or placebo condition, which represents a limitation of the study.
