Both interventions were delivered in twelve 90-minute sessions across three months. Standardized self-report measures assessed dysfunctional relationship beliefs, cognitive and experiential avoidance, conflict resolution styles, and sexual satisfaction at pretest, posttest, and three-month follow-up. Data were analyzed using repeated-measures analysis of variance, followed by Bonferroni post hoc comparisons to examine within- and between-group differences over time.</p> <p><strong>Findings: </strong>Repeated-measures analyses revealed significant group × time interaction effects for dysfunctional beliefs (total score and selected components), experiential avoidance, and conflict resolution dimensions, indicating differential change trajectories across groups (p &lt; .05). ACT-C produced significantly greater reductions than IBCT in belief in the destructiveness of disagreement, belief in spouse unchangeability, total dysfunctional beliefs, and experiential avoidance (p &lt; .05). ACT-C also led to greater improvements in positive problem solving and greater reductions in withdrawal and compliance compared with IBCT (p &lt; .05). No significant between-group differences were found for cognitive avoidance. Both ACT-C and IBCT demonstrated significant improvements over time relative to the control group on sexual satisfaction components and total score; however, between-therapy differences on sexual satisfaction were not statistically significant (p &gt; .05). Treatment gains were largely maintained at follow-up.</p> <p><strong>Conclusion: </strong>Both ACT-C and IBCT are effective interventions for improving relational and sexual outcomes in infertile couples, with ACT-C showing incremental advantages on experiential avoidance, specific dysfunctional beliefs, and key conflict resolution styles, suggesting added value of flexibility-focused processes in this population.</p> https://journals.kmanpub.com/index.php/aftj/article/download/5038/10393
