With the aim of the effectiveness of "behavioral activation based on values" on marital compatibility and forgiveness in women with the experiment of "spousal infidelity", the present research has been conducted. The research method was "quasi-experimental design" with a pre-test and post-test-follow-up design with a control group. The statistical population includes all women with a report of "spousal infidelity" who referred to the "True Counseling Center" in Gorgan city in 2018, and their number was equal to 78. Among them, 30 people were selected by "purposive sampling" and "voluntarily" methods and randomly assigned to two experimental and control groups. The experimental group underwent intervention, but the control group did not receive treatment. The tools used in this research were Spiner's "Marital Compatibility" questionnaire and Paliri et al.'s "Forgiveness of Marital Resentment" questionnaire. Using the analysis of variance test with repeated measurements hypotheses were analyzed. The results showed: the model of "behavioral activation based on values" by using techniques such as "contentment", "interruption" and "delegating" increased the compatibility and components of "marital forgiveness" in women. According to the findings of the research, it is suggested to hold training courses for people affected by "infidelity" with an emphasis on the treatment of "behavioral activation based on values".
