The Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) questionnaire. A validation study with Spanish schizophrenia spectrum outpatients.

Introduction: The Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) is a disease-specific subjective Quality of Life (QL) questionnaire for patients with schizophrenia. This study assesses the psychometric properties of the SQLS-R4 when applied to a sample of Spanish schizophrenia spectrum outpatients with stable disease.

Methods: The SQLS-R4 and EUROQOL-5D-5L were completed once by 168 schizophrenia and schizoaffective disorder patients.

The association of clinical insight and depression with quality of life in schizophrenia.

This study assesses how insight influences depression and Quality of Life (QOL) in schizophrenia-spectrum outpatients and whether depression modifies the relationship between insight and QOL. 141 patients with schizophrenia or schizoaffective disorders with stable disease completed the EUROQOL-5D-5L and SQLS-R4, SAI-E and Calgary scales. Univariate and multivariate linear regression models were fitted to assess whether insight was related to QOL and/or depression.
