Abstract
The article raises the issue of the quality of life (QoL) of adolescents during the COVID-19 pandemic, its relationships with coping and mediating role of the received social support (RSS). The nationwide survey was conducted from September 13, 2021 to October 1, 2021. The total of 4970 individuals aged 10-18 years old were researched in Poland. The KIDSCREEN-27, the Brief COPE by Charles S. Carver in the Polish adaptation and the Berlin Social-Support Scales were employed in the research. SPSS and PROCESS macro were used for descriptive, correlational, and mediation analyses. The results indicate the relationship between the perceived QoL (QoL) with active coping, seeking social support coping and helplessness coping. The essential mediating role of the RSS was confirmed for the relationship between coping with stress and QoL in the group of the individuals researched. The findings imply that both in daily and difficult situations, social systems of support should be activated to provide environment for optimal development of adolescents, diminish consequences of potential risk factors, and enhance the significance of protective factors.
