RESUMO
Over the past few decades, the role of self-views in life satisfaction has been extensively investigated. Recently, growing attention has been directed to the question of whether an optimistic worldview, termed "reward for application", helps boost life satisfaction. Conceptually, the association between reward for application and life satisfaction can be paradoxical. Due to various methodological and theoretical shortfalls, previous investigations were unable to draw a robust conclusion on this association. To address these shortfalls, two cross-lagged panel studies were conducted with different time lags. Over and above the potential confounds of self-views (namely, self-esteem and self-rated personality traits), reward for application had a positive effect on lagged life satisfaction among both adolescents and young adults, while the reverse effect was not found. Moreover, we found support for the multiplicative effect between worldviews and self-views, in which the positive effect of reward for application on life satisfaction was attenuated by high self-esteem.
