| Research Abstract |
The aims of this study were to verify a cause-effect model for depression, uncooperativeness, self-esteem, and the quality of life (QOL) and to identify variables that allow QOL predictions using a cross-sectional study and a 2-year follow-up longitudinal study, respectively.
There were 73 subjects in the cross-sectional study and 68 subjects in the longitudinal study. All were schizophrenic patients receiving daycare at 3 psychiatric hospitals. The initial (T0), 1-year (T1), and 2-year (T2) surveys were performed from August, 2002 through November, 2003 ; August, 2003 through November, 2004 and August, 2004 through November, 2005, respectively. Data obtained included QOL (WHOQOL-BREF), socio-demographics, clinical characteristics, severity of symptoms (BPRS), ability (SSAS-12), and self-esteem. Covariance structure analysis was performed to determine how well data at T0 fit the cause-effect model. Regression analysis was also performed with variables related to the QOL at T0 as indepen

dent variables and variables for QOL at T0-T2 as dependent variables.
As a result, covariance structure analysis revealed a cause-effect model for QOL was prepared with self-esteem based on depression and uncooperativeness. Thus, the goodness of fit was found to be statistically acceptable (χ^2/d.f., 1.83 ; GFI, 0.98 ; and AGFI, 0.88). Depression and uncooperativeness were negatively correlated with self-esteem, while self-esteem was positively correlated with QOL. Both QOL at T0 and QOL at T1 were predicted by gender and self-esteem, but QOL at T2 was predicted from self-esteem alone. The predictive values of self-esteem were 14.9% (T0), 17.1% (T1), and 21.0% (T2) ; the effects of self-esteem on the QOL increased over time. Depression and uncooperativeness appeared to have affected the QOL in the cross-sectional study, but they did not in the longitudinal study, presumably because there were other factors that affected self-esteem. The results of this study showed that intervention focused on improving self-esteem have the potential to improve the QOL for schizophrenic patients. Less
