Abstract

Improvement of subjective quality of life (QoL) is seen as an important treatment outcome in clinical practice. The aim of this study is to test the theoretical model of Cummins, which includes a homeostatic management system. According to this model, objective variables are almost irrelevant to general well-being, while the feeling of having an influence on one's circumstances (perceived deficit) is related to subjective QoL. The variables of the Cummins model were operationalised based on the Lancashire Quality of Life Profile, a structured interview to assess the subjective QoL of people with severe mental health problems. The Cummins model was tested using structural equation modelling and a mediator model between Objective QoL, Subjective QoL and Perceived Deficit. Subjective QoL and General Well-Being were significantly related and having a meaningful perspective in life was related to General Well-Being. Contrary to the Cummins model, both Objective QoL and Perceived Deficit had a significant relation to Subjective QoL and Perceived Deficit was a partial mediator between Objective QoL and Subjective QoL. Cummins' theoretical model was partially confirmed. The current study suggests that meaningful (treatment) evaluation of subjective QoL can only be performed if objective QoL, General Well-Being and subjective evaluation (Perceived Deficit and Framework) are taken into account.
