Quality of life (QoL) is defined as a person’s subjective or objective perception towards their physical condition, psychological, social and environmental circumstances in their daily lives. QoL enhancement has been recognized as one factor that contributes to an excellent outcome in patients with schizophrenia and cognitive function was noted as one of the determinants of QoL. Impaired cognitive function may cause the inability to work and to perform their daily activities. Hence it will eventually lead to the decreasing of their quality of life. Method : In this cross sectional study, 106 stable outpatient with schizophrenia were evaluated for quality of live and cognitive function using Lehman’s Quality of Life Interview (QOLI) and ScoRSvI. Consecutive sampling method was used and 95 people were obtained as the sample. The data was then analyzed using Pearson’s correlation anaysis. Result : The result of questionnaires performed on 95 patients shows variation in cognitive scoring, mostly on 3 (28,42%) and 4 (26,31%), meanwhile on the quality of life, most people are on the Average (80%). Pearson’s correlation analysis shows p = 0,000 where p > 0,05 and r : -0,476 indicating a negative correlation and that the strength of relationship between two variables is Average. Conclusion : It is confirmed that the cognitive function appear to have significant correlation with QoL of patients with schizophrenia
