The Mediating Role of Dispositional Optimism and Perfectionism on the Relationship Between Perceived Parental Psychological Control and Support and Adolescents’ Well-Being

Abstract

Adolescents’ psychological well-being results from the interaction between individual traits, such as optimism and perfectionism, and contextual factors. According to the Self-Determination Theory (SDT), the living environment can promote well-being by fulfilling basic psychological needs. Perceived parental support or control may influence the satisfaction of these needs and the development of dispositional traits, with significant consequences on well-being. This study, conducted on a sample of Italian adolescents (N = 500, Mage = 18; SD = 0.7), aimed to explore the mediating role of dispositional optimism and both adaptive and maladaptive perfectionism in the relationship between perceived parental support and control and adolescents’ well-being. Structural Equation Model (SEM) results showed that optimism mediated the relationship between paternal support and well-being (β = 0.029, p = 0.05), while adaptive perfectionism mediated the effects of both maternal and paternal support on well-being (β = 0.062, p < 0.001; β = 0.038, p = 0.001). In contrast, maternal control had an indirect negative impact on well-being through dispositional optimism and maladaptive perfectionism (β = −0.045, p = 0.012; β = −0.040, p = 0.009), whereas paternal control was not significant. These findings underscore the importance of supportive parenting in promoting adolescent psychological well-being and the risks associated with excessive control.
