Personality Characteristics and Interpersonal Relationship Skills in Human Aging

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.
