Due to occupational pressures and specific working conditions, nurses may be at a higher risk of experiencing this phenomenon.</span><span style="color:black"></span></span><br> <span style="unicode-bidi:embed"><span style="color:#2980b9;"><span style="display: none;">&nbsp;</span><b>Objectives:</b></span><span style="color:#003399;"><b> </b></span><span style="display: none;">&nbsp;</span><span style="color:black">The present study aimed to predict the propensity for infidelity based on quality of life and emotional literacy, with resilience serving as a mediating role in nurses.</span></span><br> <span style="color:#2980b9;"><b>Methods:</b> </span><span style="color:black">This descriptive correlational study, based on structural equation modeling (SEM), was conducted on 265 nurses in 2023-2024. Participants were recruited using a convenience sampling method. Data were collected using the Scale of Marital Infidelity (Bashirpour et al.), the Medical Outcomes Study (MOS) 36-item, Short-Form Health Survey (SF-36) (Ware & Sherbourne), the Emotional Literacy Scale (Kimiyaee), and the Connor-Davidson Resilience Scale (CD-RISC). Data were analyzed using Pearson&rsquo;s correlation in SPSS version 25 and SEM in LISREL version 8.8.</span><br> <span style="unicode-bidi:embed"><span style="color:#2980b9;"><b>Results:</b></span><span style="color:#000066;"> </span><span style="color:black">The results revealed that the propensity for infidelity had significant negative correlations with quality of life (r =&minus;0.38, p < 0.01), emotional literacy (r = &minus;0.43, p < 0.01), and resilience (r=&minus;0.49, p < 0.01). Furthermore, quality of life (&beta; = 0.41, p < 0.01) and emotional literacy (&beta; = 0.39, p < 0.01) had significant positive effects on resilience. The mediating role of resilience in the relationship between quality of life and emotional literacy with the propensity for infidelity was also confirmed (p < 0.01).</span></span><br> <span style="unicode-bidi:embed"><span style="color:#2980b9;"><b>Conclusion:</b></span> <span style="color:black">Emotional literacy and quality of life are effective variables in predicting the propensity for infidelity in nurses. Therefore, strengthening these skills can be beneficial in counseling and preventative interventions to reduce the likelihood of marital infidelity within this population.</span></span></span></span></span><br> &nbsp; Propensity for Infidelity, Quality of Life, Emotional Literacy, Resilience, Nurses 67 76 http://nmcjournal.zums.ac.ir/browse.php?a_code=A-10-1013-1&slc_lang=en&sid=1 Mohammad saeid Ahmadi ghavaghy57@cfu.ac.ir 100319475328460014511 100319475328460014511 Yes PhD in educational psychology, Assistant Professor, Department of Psychology and Counseling, Farhangian University, Tehran, Iran Hossein Masoomi Jahandizi hmjfh@zums.ac.ir 100319475328460014512 100319475328460014512 No PhD in Educational Psychology, Faculty member of Zanjan University of Medical Sciences, School of Health, Department of Public Health, Zanjan Maryam Mohammadloo Maryam_mohamadlou@yahoo.com 100319475328460014513 100319475328460014513 No PhD in Psychology, Islamic Azad University, Semnan, Iran Mina Alinejad Mina.alinejad100@gmail.com 100319475328460014514 100319475328460014514 No Master of Clinical Psychology, Islamic Azad University, Zanjan, Iran
