Each intervention was performed twice a week for 3 days. At the end of treatment all three groups were tested. Findings: The finding showed that there is a significant difference between the experimental group under the influence of Acceptance and Commitment Therapy and Schema Therapy in post-test resiliency. F (1.41) = 530/35. Conclusion: The results showed that schema therapy is more effective on resiliency than, Commitment-Based and Acceptance.
