Most of the evidence concerns the SF-36 and EQ-5D , and for these instruments there was evidence for known group validity .
Although the evidence base is limited in a number of important respects , including problems with the measures used to develop constructs in the validation studies , it is sufficient to raise doubts about the use of generic measures of health like the EQ-5D and SF-36 in patients with schizophrenia
OBJECTIVES Generic health status measures such as the short form health survey ( SF-36 ) and EuroQol-5D ( EQ-5D ) are increasingly being used to inform health policy .
They are cl aim ed to be applicable across disease areas and have started to be used within mental health research .
This review aims to assess the construct validity and responsiveness of four generic health status measures in schizophrenia , including the preference-based SF-6D and EQ-5D .
Development and validation of a patient-based health-related quality of life questionnaire in schizophrenia: the S-QoL
We developed a self-administered instrument to assess  health-related quality of life ( HRQL ) among people with schizophrenia . The S-QoL , based on Calman 's approach to the subject 's point of view , is a multidimensional instrument that is sensitive to change . The scale is a 41-item question naire with eight subscales ( psychological well-being , self-esteem , family relationships , relationships with friends , resilience , physical well-being , autonomy and sentimental life ) and a total score . In-depth interviews with patients determined the pertinent issues for item development . The validation study , performed with 207 patients , showed high internal consistency reliability , reproducibility and responsiveness . Construct validity was confirmed using established clinical and HRQL measures . S-QoL covers domains that differ from areas tapped in other measures , with greater responsiveness . The S-QoL is an efficient instrument for the measurement of the impact of schizophrenia  on individuals ' lives
