Summary

The quality of life concept has been increasingly used as a major tool for patient care and clinical investigations. The Heinrichs quality of life scale (QLS) is the quality of life assessment method widely used in schizophrenic patients. The QLS was translated into its French version by J.D.Guelfi according the back-translation method. This version of the validation study included 60 schizophrenic inpatients. The scale possesses acceptable psychometric qualities. The test-retest reliability is good for nearly all items of the scale and for the categories and overall score. The internal consistency alpha-coefficients were 0.9 for the global score and varied between 0.6 and 0.9 according to the category. Factor analysis elicited four factors. Convergent validity is good. Recommendations for future use of the QLS are proposed.
