This study investigates the impact of individuals' family of origin position (birth order) and internal dynamics on decision-making processes and conflict resolution strategies within their marital unions. Recognizing that marital satisfaction and stability are influenced by the interpersonal patterns learned in one's family of origin, this research explores how birth order roles and familial communication styles are replicated or adapted in spousal interactions. Using a mixed-methods design, quantitative data were collected from a purposive sample of 150 married couples, measuring birth order, decision-making dominance, and preferred conflict resolution styles. Qualitative data from in-depth interviews with a subset of 20 couples were analyzed to explore the subjective experiences and dynamics behind the numerical trends. Findings reveal that complementarity and conflict in birth order roles between spouses (e.g., a firstborn married to a lastborn) significantly influence decision-making dominance and the adoption of constructive versus destructive conflict management strategies. The study highlights the enduring influence of familial background on marital functioning and underscores the importance of conscious awareness of these patterns for fostering healthy, equitable, and resilient marriages.
