Revised Schizophrenia Quality of Life Scale Found Highly Sensitive

Key clinical point: In adults with schizophrenia, the Schizophrenia Quality of Life Scale Revision 4 (SQLS-R4) demonstrated a high level of sensitivity and similar validity to the EuroQoL-5D-5L, a generic quality of life self-report questionnaire.

Major finding: The SQLS-R4 is a disease-specific subjective quality of life measure that showed strong convergent validity with the EuroQoL-5D-5L, with the strongest correlations (Spearman’s Rho greater than 0.60) between psychosocial feelings, vitality, and SQLS-R4 global score, and EuroQoL-5D-5L anxiety/ depression subscore.

Study details: The data come from a study of 168 adults with schizophrenia or schizoaffective disorders who had stable disease and mild or no positive symptoms.

Disclosures: The researchers had no financial conflicts to disclose.
