Participants included 13 conflicted couples referred to counseling centers in Shiraz and 4 expert family counselors, selected through purposive sampling. Data were collected using semi-structured interviews until theoretical saturation was reached. Analysis was carried out through open, axial, and selective coding to generate the emerging concepts and model.<br> <b>Results</b>: Analysis revealed that marital conflict is influenced by multiple interrelated factors, including: tension with traditional family structures; family members&rsquo; persistent control and interference; inadequate emotional support; unresolved childhood wounds; chronic psychological stress; couples&rsquo; cognitive and emotional shortcomings; and breakdowns in communication patterns. These factors jointly contribute to both the emergence and persistence of marital conflict.<br> <b>Conclusions</b>: The resulting conceptual model provides a context-sensitive framework that deepens understanding of the dynamics of marital conflict within extended family systems. The model highlights how individual vulnerabilities, relational processes, and family-of-origin influences intersect to shape couples&rsquo; conflict experiences, offering implications for counseling and intervention programs.</span></span></span></span></div> Model developing, Marital conflict, Family of origin, In-laws 0 0 http://ieepj.hormozgan.ac.ir/browse.php?a_code=A-10-1090-1&slc_lang=en&sid=1 Esmail Zohrei e.zohrei@iau.ac.ir 100319475328460011921 0009-0009-3052-4255 No Department of Psychology & Counselling, Ya.
