Background and Objectives: Improving or reducing the stress caused by cancer in patients is possible with different psychological approaches. Therefore, we compared the effectiveness of spiritual therapy and acceptance and commitment therapy on life expectancy (LE) and quality of life (QoL) of cancer patients. Methods: This quasi-experimental study with the pre-test and post-test and follow-up design and a control group was conducted in ۲۰۲۰, in which we randomly selected ۴۵ cancer patients admitted to the Taleghani Hospital in Kermanshah Province who were divided into three groups: spiritual therapy, acceptance and commitment therapy, and control groups. After the treatment, we compared the three groups’ scores on the QoL questionnaire and LE questionnaire by Schneider by SPSS software, version ۲۰ and analysis of covariance. Results: The mean age of patients was ۲۸±۱۴ years. A family history of cancer was observed in ۱۴% of patients. There were no significant differences in the pre-test (۱۷.۰۴±۲.۳۵) and post-test (۱۸.۱۹±۲.۱۱) scores of LE in the control group. The results of the analysis of covariance showed a significant difference (P<۰.۰۱) between the post-test scores of QoL and LE in the treatment groups compared to the control group. Conclusion: Both types of treatments were effective in patients and increased their QoL and LE. However, spiritual therapy had a greater effect on the QoL and LE among cancer patients compared to acceptance and commitment therapy
