Abstract
ObjectiveWe 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).MethodsThe 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.ResultsThe 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.ConclusionsPsychological 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.
Highlights
The number of Europeans aged 65 and over is expected to increase from 17.4% to 25.6% until 2030, and even up to 30% of the population by 2060 due to both the aging of Baby Boomers and increasing life expectancy [1]

Summary
The number of Europeans aged 65 and over is expected to increase from 17.4% to 25.6% until 2030, and even up to 30% of the population by 2060 due to both the aging of Baby Boomers and increasing life expectancy [1]. The concept of QoL includes two main dimensions: the feeling of well-being and the health related quality of life (HRQol) which are strong indicators of successful aging [2,3]. The distinction of these two dimensions is interesting since well-being may be more sensitive to psychological aspects than measures of HRQoL. No previous study yet included the role or the mediation of all of these predictors in the evaluation of the QoL of aging people Considering their potential impact, it could be useful for practitioners to consider these psychological dimensions to plan appropriate interventions aimed to promote successful aging [4]. The objective of the study was to characterise the relationships of psychological and psychosocial dimensions with the QoL of aging individuals
