Materials and Methods: The present pretest-posttest study with a control group design was conducted on patients with COVID-19 obsession in 2021. The required information was collected using the COVID-19 obsession scale, a short form of psychological distress, and a tolerance of ambiguity questionnaire. The experimental group obtained ten 90-minute classes of cognitive-behavioral therapy based on mindfulness. The adjusted post-test scores were compared using an analysis of covariance.

Cognitive-behavioral therapy based on mindfulness significantly reduced anxiety (F=41.99, P=0.001, η2=0.63), depression (F=27.19, P=0.001, η2=0.53), stress (F=26.92, P=0.001, η2=0.52), and increases tolerance of ambiguity (F=31.63, P=0.001, η2=0.57), in patients with COVID-19 obsession disorder. Conclusion: The findings indicated that cognitive-behavioral therapy based on mindfulness appreciably improves the mental health of sufferers with COVID-19 obsession.
