Long-Term Advantages of Adolescent Optimism: Nonlinear Associations With Adult Outcomes and its Protective Role in Buffering Socioeconomic Risk

This study examined whether optimism in early adolescence predicts occupational and psychosocial outcomes in early adulthood and explored the functional form of this relation. We also investigated whether these associations continue to hold after accounting for concomitant factors and whether optimism acts as a protective factor that helps early adolescents deal with socioeconomic adversity. We followed a large sample of German seventh graders (N = 1596; 63.8% females; baseline Mage = 12.9) at two measurement points over a period of 18 years and estimated latent regression models. Optimism in early adolescence predicted several adult outcomes, including occupational prestige, social integration, psychosocial symptoms, and depression. Analyses with social integration, depression, and life satisfaction revealed a nonlinear association: Optimism promoted life outcomes, but this positive association reached a plateau in above-average ranges of optimism and a minimum value in below-average optimism ranges. Moreover, optimism in early adolescence buffered the negative effects of low parental socioeconomic status on occupational prestige, job satisfaction, and psychosomatic symptoms in adulthood. The findings offer increased knowledge about the long-term significance of optimism and underscore the necessity of considering these effects from a more comprehensive and interactional point of view.
