“…The literature search and the material extracted from that search, while not necessarily representing all publications in the field, showed that in general, there are many research reports that encompass one or more aspects of the theme of ‘successful aging’, but there is no comprehensive universally accepted model of the concept, and the concept is defined by a myriad of differing definitions, such as having achieved successful adaptations to an aging body [ 4 ], the absence of disease and disability [ 5 ], resilience/adaptation [ 6 ], and selective optimization with compensation [ 7 ]. As well, an array of research approaches, such as in-depth interviews conducted face to face or by phone [ 4 , 5 , 8 ], focus groups [ 6 ]; questionnaires [ 7 ], life story interviews [ 9 ], concept analysis [ 2 , 10 ], literature reviews [ 3 , 11 , 12 , 13 , 14 ] prevail. In addition, most studies examined small convenience samples of healthy cohorts of varying ages, and very few reports could be found that were devoted to the application of the concept of ‘successful aging’ to the osteoarthritis population.…”
