In this study, predictors of quality of life (QOL) in psychiatric outpatients (n = 410) were investigated using the psychological stress model developed by Taylor and Aspinwall (Psychosocial Stress. Perspective on Structures, Theory, Life-Course and Methods. San Diego, CA: Academic Press, 1996; pp. 71-110). External resources, personal resources, stressors, appraisal of stressors, social support, coping, and QOL were assessed with several questionnaires. The complete original Taylor and Aspinwall model was tested with SEM analyses. These analyses were not able to explain the data adequately. Therefore, initially a more exploratory data analytic strategy was followed using a series of multiple regression analyses. These analyses only partially supported the Taylor and Aspinwall model. In fact, QOL was not predicted by coping, while all other antecedents affected QOL directly, explaining considerable amounts of QOL variance. As a next step, taking the outcomes of the regression analyses as point of departure, new SEM analyses were carried out, testing a modified model. This model, without coping, had an excellent fit. Consequently, modifications of the model are recommended concerning psychiatric outpatients when QOL is the psychosocial outcome measure.
