A sample of patients with chronic hepatitis B was selected from all patients visiting specialized clinics in Tehran -Iran in 2021. Thirty patients with hepatitis B were selected and randomly allocated to two experimental and control groups (15 patients per group). Eight sessions of group CBT (one 90-minute session per week for two months) were performed, and the post-test was then administered to both groups. The data was collected by the Health Promoting Lifestyle Profile-II (HPLP-II) and analyzed via the analysis of covariance (ANCOVA) and t-test in SPSS 26.</span></span></span></span></span><br> <span style="font-size:12pt"><span style="line-height:150%"><span style="font-family:Calibri,sans-serif"><span style="line-height:150%"><span new="" roman="" style="font-family:" times="">&nbsp;<b>Results: </b>There was no significant difference between the lifestyle mean score of the groups in the pre-test stage.
