The French version of the Lancashire Quality of Life profile was evaluated in 60 patients treated in a day hospital and an outpatient clinic. All patients were diagnosed with schizophrenia using the ICD-10 scale. Both groups were age matched, with the exception that patients treated in a day hospital had more severe illness, compared with those treated as outpatients. Data from the French version of the Lancashire Quality of Life profile were compared to data obtained from the following scales: Global Assessment Scale, Clinical Global Impression Scale, Positive and Negative Syndrome Scale, and Daily Attitude Inventory.

The results indicate differences between the two patient groups with respect to both objective and subjective quality of life. Compared with patients treated in a day hospital, patients treated in the outpatient clinic were more satisfied with their work, life, and overall well being. Correlations were found between level of symptomatology and patient satisfaction. This was apparent in areas such as living conditions, social and family relations, health, and well being. No correlation was found between objective and subjective quality of life.

Comparing ratings of global level of symptomatology with the Clinical Global Impression Scale and the Positive and Negative Syndrome Scale, the study demonstrated that the French version of the Lancashire Quality of Life Profile accurately measured domain-specific and global quality of life, and could be used to assess quality of life in patients with schizophrenia.
