Associations between cognitive impairment and quality of life in schizophrenia

Abstract

BACKGROUND: The Quality of Life (QoL) is a valuable way of assessing the impact of diseases in daily life and favors more effective interventions under a biopsychosocial perspective. OBJECTIVES: This article aimed to critically analyze the available data on the relationship between QoL and cognitive function in schizophrenia. METHODS: We performed a search in PubMed and Lilacs databases with the terms "schizophrenia" and "cognition disorder" or "cognition" and "quality of life" or "outcome assessment". RESULTS: From the 27 selected articles that studied the relationship between cognition and QoL measured by scales, 20 articles showed associations. The association was more robust in studies using scales administered by a researcher, compared to self-report scales. DISCUSSION: The cognitive assessment is important not only as a parameter for determining QoL of patients, but also as a factor to be taken into account when analyzing the data obtained by self-report QoL scales.
