ABSTRACT
This study aimed to examine health-related quality of life of adolescents before and during the COVID-19 outbreak, and its relationship to resilience embodied in hope and a sense of coherence. Typically developed adolescents between the ages of 13 to 18 participated in the study; 84 were recruited before the pandemic outbreak and 64 in March to April 2020 during the worldwide outbreak. The participants completed the Pediatric Quality of Life Inventory, Sense of Coherence Scale, and Children's Hope Scale. During the outbreak, adolescents reported higher physical health-related quality of life scores (F(1146) = 3.710, p < 0.05, η² = 0.027) and lower school health-related quality of life scores (F(1146) = 5.748, p < 0.05, η2 = 0.028), compared to adolescents during the pre-outbreak period. Furthermore, adolescents during the outbreak reported a significantly (p < 0.05) higher sense of coherence but no difference in levels of hope. Finally, the results of multiple linear regression indicated that resilience factors (hope and sense of coherence) contributed to the prediction of health-related quality of life, independent of socio-demographic variables. Hope and a sense of coherence were both found to positively impact one core aspect of health, which highlights the importance of addressing resilience factors in educational and therapeutic settings for adolescents thus that they are better able to adapt to stressful events such as pandemics.
