Objective: This study was carried out to estimate the effectiveness of cognitive-behavioral therapy based on mindfulness of psychological distress and tolerance of ambiguity in patients with COVID-19 obsession . Materials & 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. Results: The mean age of participants in the experimental and control group was 31.84 (standard deviation (SD)=4.68) and 34.09 (SD=7.05) years, respectively. 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. Considering the long-term effects of COVID-19, psychology and counseling facilities should take measures to become aware of and treat vulnerable groups. }, URL = {http://cjhr.gums.ac.ir/article-1-269-en.html}, eprint = {http://cjhr.gums.ac.ir/article-1-269-en.pdf}, journal = {Caspian Journal of Health Research}, doi = {10.32598/CJHR.8.1.362.1}, year = {2023} }
