FARINA, Marianne et al. Personality Factors and Health Aspects in Older Adults: A Longitudinal Study. Psicol. teor. prat. [online]. 2023, vol.25, n.1, ePTPPE13383.  Epub 14-Mar-2025. ISSN 1516-3687.  https://doi.org/10.5935/1980-6906/eptppe13383.en.

The Big Five Personality Factors Model is a contemporary theory that effectively assists in understanding an individual’s personality features. Therefore, the present study sought to compare the older adults’ big five personality factors (neuroticism, conscientiousness, openness to experience, agreeableness, and extraversion) before and after a four-year interval and to identify the predictive effect of these factors on health variables. This is a quantitative and longitudinal study. The sample consisted of 60 older adults with a mean age of 73.17 years (SD = 5.99). The following instruments were applied: 1) Sociodemographic and Clinical Data Questionnaire; and 2) Personality Factorial Battery (PFB). The main findings revealed significant changes in the scores of three personality factors over four years: extraversion, conscientiousness, and agreeableness. In this context, the time variable had a significant influence on personality factors.
