Background Sudden and unpredictable changes caused by the COVID-19 pandemic have profoundly threatened the psychological well-being and increased insecurity among adolescents worldwide. At a critical developmental stage, the well-being of the youth is more vulnerable to adverse environments. This study constructed a moderated mediation model to explore the buffering factors between insecurity and subjective well-being of the youth during the pandemic. Methods During the COVID-19 outbreak in June 2020, data of 5,503 Chinese youth (15–29 years old) were collected via an online questionnaire. Subjective well-being, insecurity, self-control, and hope were measured, and the moderated mediation model was analyzed. Results Findings from this study showed that with the mediating effect of self-control, insecurity negatively predicted subjective well-being, and hope moderated the association between insecurity and self-control. Specifically, the link between insecurity and self-control was stronger when hope was low but weaker when hope was high. Limitations Since this study was mainly conducted in China, and considering the continuous change of the pandemic on a global scale, it is of great significance to conduct cross-cultural and cross-time studies in the future. Conclusions The results demonstrate that self-control and hope play important roles in buffering the negative effects of insecurity on the subjective well-being of adolescents and young adults. The findings provide implications for reducing the negative impact of insecurity from a positive psychology perspective and for youth mental health interventions during public health crises.
