We sought to identify a core subset of Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) items that maintains the validity and psychometric properties of the basic version. A parsimonious subset of items from the Q-LES-Q that can accurately predict the basic Q-LES-Q domain mean scores was sought and evaluated in 339 inpatients meeting DSM-IV criteria for schizophrenia, schizoaffective, and mood disorders. Three additional data sets were used for validation. Assessments included Q-LES-Q, Quality of Life Scale, Lancashire Quality of Life Profile, rating scales for psychopathology, medication side effects, and self-reported emotional distress, self-esteem, self-efficacy, and social support. We found that 18-items predicted basic Q-LES-Q domains (physical health, subjective feelings, leisure time activities, social relationships) and general index scores with high accuracy. Q-LES-Q-18 showed high reliability, validity, and stability of test-retest ratings. Thus, Q-LES-Q-18, a brief, self-administered questionnaire may aid in monitoring quality of life outcomes of schizophrenia, schizoaffective, and mood disorder patients.
