Modeling women's quality of life after cardiac events.

Quality of life (QOL) is presented as a global, unidimensional, and subjective assessment of one's life. This study examined the impact of perceived health status, hope, and optimism on QOL in 93 women after suffering a cardiac event. Construct validity was examined by estimating a model where QOL was measured with four indicators, and perceived health was measured with the SF-36 Health Survey. Hope was measured with the Herth Hope Index and dispositional optimism was measured with the Life Orientation Test. The unidimensionality of QOL and its response to health status, hope, and optimism were tested. Fit indices suggested that the theoretical relations posited were compatible with the data, (chi 2(42) = 44.125, p = .382, RMSEA = .0001, GFI = .942). The model explained 66% of the variance in QOL. Modeling suggested the presence of a complex latent concept composed of hope and optimism that influenced QOL.
