The Effectiveness of Rollo May Existential-Humanistic Approach to the Willingness toInfidelity in Disloyal Men: A Single Case Study

The present study investigated the effectiveness of Rollo's Existential-Humanistic Approach to the willingness to infidelity in disloyal men. The present study was a single case study (A-B phase design). The research population included men involved in marital infidelity in Shahindaj in 2021. The participants were three people who were selected using purposive sampling to participate in treatment. The data were collected using the Whitley Attitudes toward Infidelity Scale (ATIS). The intervention was performed individually, two sessions per week for 120 to 160 minutes on the participants. The collected data were analyzed using visual analysis, the change stability index, and the recovery rate formula. The visual analysis of the curves for the tendency to marital infidelity in the intervention stage showed that the two variables underwent a downward trend and the change stability index of both variables was greater than 1.96. Furthermore, the tendency to marital infidelity and existential crises were improved by 41.66% and 31%, respectively, indicating that the intervention implemented following Rollo's approach had a significant impact on these two variables. Based on the findings of the present study, it can be concluded that therapists can use the Rollo's existential-humanistic approach as an efficient model to reduce existential crises in clients and also reduce the tendency to infidelity in the individuals or couples engaged in marital infidelity.
