From Growth Mindsets to Life Satisfaction: Examining the Role of Cognitive Reappraisal and Stressful Life Events

<b>Background/Objectives:</b> Implicit theories of thoughts, emotions, and behavior (TEB) describe beliefs that these attributes are either changeable (growth mindset) or unchangeable (fixed mindset). While the impact of mindsets on negative mental health indicators, such as psychopathological symptoms, is well-documented, their relations with positive indicators such as life satisfaction, particularly in the context of stress, remain underexplored. This study aimed to address this gap by testing whether the association between adolescents' implicit theories of TEB and life satisfaction is mediated by cognitive reappraisal and whether stressful life events moderated two paths within the mediation model. <b>Methods:</b> Participants were 620 high school students (49.5% female, 43.5% male, 5.8% gender-nonconforming, 1.1% undisclosed) aged 14 to 19 years (M = 17.51, SD = 1.23), who completed an online survey in Spring 2022, while the COVID-19 pandemic still significantly affected daily life. Mediation and moderated mediation models were tested using PROCESS macro in SPSS. <b>Results:</b> Mediation analysis revealed that growth mindset positively influenced life satisfaction both directly and indirectly through cognitive reappraisal. Stressful life events significantly moderated the direct effect of growth mindset on life satisfaction, with the positive direct effect diminishing as stress increased. <b>Conclusions:</b> The positive link between growth mindset and life satisfaction was strongest under lower stress and transmitted through cognitive reappraisal across stress levels. Given the cross-sectional design, findings should be interpreted as correlational, not causal. Future longitudinal research should clarify temporal directionality and reciprocal links among mindset, coping, and well-being to inform interventions that strengthen adaptive beliefs and regulation skills.
