The statistical population comprised women attending psychological clinics in Western Tehran during 2024–2025. Forty-five eligible participants were selected through purposive sampling and randomly allocated to MCT, NR, and control groups (n = 15 each). The two experimental groups received ten sessions of their respective interventions, whereas the control group received no intervention during the study period. Data were collected using the Dysfunctional Attitudes Scale (DAS-26) and the Prolonged Grief Disorder-13 (PG-13) scale. Mixed-design analysis of variance and Bonferroni post-hoc comparisons were performed using SPSS version 26.</p> <p><strong>Findings:</strong> Mixed ANOVA revealed significant time-by-group interaction effects for dysfunctional attitudes, F(4,84) = 33.71, p &lt; .001, η² = .616, and grief symptoms, F(4,84) = 9.63, p &lt; .001, η² = .314. Bonferroni comparisons showed that both MCT and NR significantly reduced dysfunctional attitudes compared with the control group (MD = 23.435 and 39.697, respectively; p &lt; .001). NR was also significantly more effective than MCT in reducing dysfunctional attitudes (MD = 16.262, p &lt; .001). Both MCT and NR significantly reduced grief symptoms relative to the control group (MD = 3.180 and 4.179, respectively; p &lt; .001); however, the difference between the two interventions was not statistically significant (MD = 0.999, p = .192).</p> <p><strong>Conclusion:</strong> Both MCT and NR are effective interventions for reducing prolonged grief symptoms in women with PGD, whereas NR appears to have greater efficacy in modifying dysfunctional attitudes and underlying maladaptive cognitive schemas. These findings support selecting psychotherapeutic approaches according to the dominant cognitive and emotional mechanisms maintaining prolonged grief.</p> https://www.journalecs.com/index.php/ecs/article/download/456/429
