Method: Anonymous online multi-national/language survey in the general population (representative/weighted non-representative samples, 14-17years), measuring change in well-being (WHO-5/range=0-100) and psychopathology (validated composite P-score/range=0-100), WHO-5 <50 and <29, pre- versus during COVID-19 pandemic (26/04/2020-26/06/2022). Coping strategies, nine a-priori defined individual/cumulative risk factors were measured. χ2, penalized cubic splines, linear regression, and correlation analyses were conducted. Results: Analyzing 8,115 of 8,762 initiated surveys (representative=75.1%), the pre-pandemic WHO-5 and P-score remained stable during the study (excluding relevant recall bias/drift), but worsened intra-pandemic by 5.55±17.13 (standard deviation) and 6.74±16.06 points, respectively (effect size d=0.27 and d=0.28). The proportion of adolescents with WHO-5 scores suggesting depression screening (<50) and major depression (<29) increased from 9% to 17% and 2% to 6%. WHO-5 worsened (descending magnitude, with cumulative effect) in adolescents with a mental or physical disorder, female gender, and with school closure. Results were similar for P-score, with the exception of school closure (not significant) and living in a low-income country, as well as not living in a large city (significant). Changes were significantly but minimally related to COVID-19 deaths/restrictions, returning to near-pre-pandemic values after >2 years. The three most subjectively effective coping strategies were internet use, exercise/walking, and social contacts. Conclusion: Overall, well-being/mental health worsened (small effect sizes) during early stages of COVID-19, especially in vulnerable subpopulations. Identified at-risk groups, association with pandemic-related measures, and coping strategies can inform individual behaviours and global public health strategies.20252025-09-12 10:47:44Članek v reviji21723sl
