Abstract
Abstract This longitudinal study aimed to assess personality characteristics and interpersonal relationship skills over time. The participants were 20 trade workers, non-patients, between 18 and 56 years old, who answered a sociodemographic questionnaire, the Social Skills Inventory (SSI2-Del Prette), and Zulliger in the Comprehensive System (ZSC). The first assessment (Test) took place between 2009 and 2019; the second (Retest) in 2021 (M=7.7 years; SD=3.8). No statistically significant differences (ANOVA) were evidenced in the assessed personality characteristics (ICC 0.40 to 0.81) and the interpersonal relationship skills remained good and excellent. The study contributes to a broader understanding of personality aspects and relational skills in human aging.
