Purpose: This study aimed to examine how participants aged 80 years old or over describe their mental well-being-exploring the suitability of the model of healthy ageing when outlining the mental well-being concept.Methods: Six structured focus group interviews with 28 participants were conducted in Western Finland in 2017. Qualitative content analysis was performed, where both manifest and latent content was considered in a process involving meaning condensation and coding, followed by categorization.Results: The healthy ageing model constituted a useful framework for the conceptualization of mental well-being, illustrating the links between these two constructs. The analysis resulted in a four-dimensional model of mental well-being in oldest old age, the key components being: Activities-enjoyment and fulfilment; Capability-functioning and independence; Orientation-awareness, shifted perspectives and values; and Connectedness-sense of belonging.Conclusions: Although functional status plays an important role for well-being in general, it is not the principal component of self-reported mental well-being within the heterogeneous group of the oldest old. Further, many persons in this age group do not view themselves as passive or dependent, on the contrary, they underline the importance of empowering attitudes, a positive mindset and actively creating circumstances which support their mental well-being.
