Depression and quality of life in old age: a closer look

Depressive disorders are among the most widespread mental disorders in old age, with negative consequences for quality of life (QOL). Understanding QOL as a multidimensional construct, in this article we have a closer look on what specific aspects are affected by depression. We used a representative sample of the German population (n = 805) and one of individuals diagnosed with depression (n = 106) to compare QOL using the WHOQOL-BREF and the WHOQOL-OLD. Multivariate analysis showed that individuals diagnosed with depression exhibited lower QOL with regard to WHOQOL-BREF-dimensions physical health, psychological, social relationships and global QOL and with regard to WHOQOL-OLD-facets sensory abilities, past, present, and future activities and social participation. In addition, in the regression analysis, there were no significant differences between individuals with and without depression with regard to environment (WHOQOL-BREF), autonomy, death and dying, intimacy and overall (WHOQOL-OLD). Associations between depression and QOL in older age are selective in terms of which aspects of QOL are affected. From a methodological perspective, a multidimensional approach to QOL is recommended. From a clinical perspective, our research highlights those areas of QOL that are relevant for health professionals working with older people and that could be the focus of interventions.
