Family member marginalization, or feeling different, not included, or not approved of by family, is a chronically stressful interpersonal process with negative mental and physical health consequences. Framed by hurtful communication, this study took an interpretive approach to understanding the process of marginalization in families. Across 30 marginalized family members, 184 turning points were reported, which were organized into 22 event categories and 4 supracategories. Communication events included disclosures, ceasing contact, and deception, among others. The most commonly reported turning points were “normative” life events such as weddings and having children. Five trajectories captured the process of marginalization. Ambivalent events and a new way of understanding the underlying motivations behind turning points are forwarded, with implications for interpersonal process scholars.
