“…In the past years, QOL has become an important outcome measure for those patients, although the associations between predictors and QOL are rather unclear. Several cross-sectional studies have investigated the relationship between the subjective QOL of people with severe mental disorders and socio-demographic and clinical characteristics (Norman et al, 2000;Fitzgerald et al, 2001;Becchi et al, 2004;Caron et al, 2005aCaron et al, , 2005bHofer et al, 2006;Narvaez et al, 2008;Hsiao et al, 2012;Fujimaki et al, 2012).
