Background. Despite the increasing importance of quality of life in the mental health Želd, the
theoretical conceptualization of the construct remains poorly developed. A proposed mediational
model of quality of life, which links subjective quality of life with self-related constructs, is examined
with a group of long-term psychiatric hostel residents. The present study aims to develop a measure
of quality of life based on the proposed model, to explore the data and their implications for service
development and Žnally to conduct a preliminary analysis of the model's predictions.
Method. A cross-sectional research design was employed. Quality of life interviews, using a modiŽed
version of Lehman's Quality of Life Interview, were carried out with 54 psychiatric residents in
Greece. The model's predictions were examined by using a series of regression analyses.
Results. The results indicate that perceived improvements in lifestyle, greater autonomy and positive
self-concept are signiŽcantly and directly associated with better quality of life. In contrast, a direct
relationship between objective indicators and subjective quality of life was not found.
Conclusions. The traditional two-part quality of life model that includes objective indicators of life
circumstances and subjective indicators is extended to included the constructs of self-concept and
perceived autonomy. The present extended mediational model of quality of life for individuals with
long-term mental health problems appears to have important implications for the planning and
delivery of mental health programmes.
