The thesis commences with a review of the literature on eating disorder (ED) symptoms and Quality of Life (QoL). Limitations of the research are discussed, and gaps in understanding are identified. The review concludes with a discussion on the measurement of QoL in ED research, and summarises the needs of research in this area. Following from this, the empirical paper investigated whether eating behaviours, general psychopathology, coping styles, and social support moderate the relationship between ED symptoms and QoL. Female students completed questionnaires on ED symptoms, QoL, general psychiatric symptoms, coping styles, and levels of social support. ED symptoms were found to be associated with QoL, and general psychiatric symptoms and maladaptive forms of coping moderated this relationship. The results are considered in relation to prior research, and methodological limitations as well as clinical implications are discussed.
