Family conflict is a core concept within family studies and related social sciences that investigates the processes, patterns, and manifestations of opposition, discord, or strain among family members. This research area examines the sources, characteristics (including intensity, frequency, and expression), and consequences of disagreements and tensions across different family subsystems and developmental stages. Its significance lies in its role as a salient predictor of relational quality, individual well-being, and systemic functioning, informing theoretical understanding and clinical interventions.
