Objective We conducted a cross-sectional survey in France in a cohort over 55 years of age to characterize the impact of psychological dimensions on quality-of-life (QoL). Methods The predictors of QoL in relation with aging were studied using an adapted quality-of-life model, based on emotional, cognitive and physical symptoms, functional status, and general health perception. Adding psychological dimensions such as self-esteem, psychological distress, perceptions of ageing and coping, was hypothesized to improve the QoL model. Responses were analyzed using structural equation modeling and path analysis. Results The study involved 258 participants, mean age 66.9±7.9 years. Psychological distress and positive perception of aging exhibited the strongest direct impact on QoL (p<0.0001). Psychological distress also appeared to be mediator on QoL for perceived health status, self-esteem and negative perception of aging. Coping centred on emotion exhibited direct impact on self-esteem and so, indirect impact on QoL (p = 0.0002). Perception of personal financial situation (p = 0.0007) and coping centred on social support (p = 0.02) appeared as direct mediators influencing QoL. Conclusions Psychological dimensions are predictors of QOL and have to be taken into account to maximize the resources with a view to successful aging. Further interventions targeting successful aging should focus on positive perception aging.
