RESUMEN
PURPOSE: To investigate the associations between internalizing problems, metacognition problems, and mindfulness levels in university students during the COVID-19 pandemic. DESIGN AND METHODS: Depression, anxiety, and stress levels were compared between university students quarantined in dormitories and their homes under curfew conditions. The direct and indirect associations between internalizing problems, metacognition problems, and mindfulness levels of students under quarantine were evaluated. FINDINGS: Metacognition problems and low mindfulness levels were associated with higher depression, anxiety, and stress symptoms under quarantine conditions. PRACTICE IMPLICATIONS: Therapeutic interventions focusing on metacognition problems and mindfulness levels may reduce the negative psychological effects of quarantine.
