“…To our knowledge, the advantages associated with the use of generic QOL questionnaires compared to disease-specific questionnaires are more variable. In previous studies, the SF-36 or sickness impact profile was a better indicator of health-related QOL in patients suffering from calcaneal fractures [27], systemic lupus erythematosus [28], epilepsy [29] or asthma [30]. On the contrary, although several generic QOL questionnaires including SF-36 were more comprehensive in coverage of different health status domains, the disease-specific QOL questionnaires had better psychometric properties than did the generic QOL questionnaires in coronary artery disease and congestive heart failure [31], or multiple sclerosis [32] and had a better ability to predict treatment outcome in total joint arthroplasty [33], carpal tunnel syndrome [34], peripheral arterial disease [35], transurethral resection of the prostate [36], carpal tunnel syndrome [37], chronic sinusitis [38] or varicose veins [39].…”
