Abstract The objective of this systematic literature review was to investigate the variables that would improve well-being in retirement by analyzing relevant empirical studies. In the literature search, six keywords (retirement, positive psychology, well-being, satisfaction, happiness and quality of life) were used in six international academic portals. This search identified 403 articles, and those meeting the pre-established inclusion criteria were extracted. The 55 articles selected were analyzed based on nine categories: language, year, journal, country, objective, dependent variable, instruments, independent variables and results. The studies had a longitudinal, transversal design or reported on instrument creation and validation. The literature review pointed out a large number of variables, confirming the multidimensionality of the constructs. Aspects highlighted include health, economic situation, gender, marital status, interpersonal relationships, whether retirement was voluntary, retirement duration and leisure activities. A compilation of variables and an agenda for future studies are proposed based on the results of this review.
