Retirement Resources Inventory in Portugal: An Adaptation and Validation Study

Abstract

A quarter of Portugal’s population is aged 65 years or over, mostly retired individuals. However, there is a lack of studies and instruments to facilitate retirement planning. This study aims to validate the Retirement Resources Inventory in Portugal to use it in future interventions. In total, 450 Portuguese retirees from all regions who responded to the inventory and sociodemographic questions participated in this study. According to the exploratory and confirmatory analyses, 23 items were found, confirming the four-factor model [χ2(gl) = 404.63(216); CFI = 0.90; TLI = 0.88; RMSEA = 0.06; SRMR = 0.06], with good evidence of internal and convergent validity. The first factor corresponded to physical and financial aspects, the second to social and family resources, the third to received support, and the fourth to emotional and cognitive resources. We recommend the replication of the RRI in a longitudinal study before and after retirement.
