Marginalized family identity theory: A framework to understand experiences in <scp>LGBTQIA</scp>+ and diverse family structures

Abstract Using an intersectional lens, existing literature, and theories to inform and ground this work, we propose marginalized family identity theory (MFIT). MFIT is a new theoretical framework to understand shared family identities in families shaped by the marginalized individual identity of one or more members. We center the experiences of Queer (LGBTQIA+) parent families, yet we also discuss how this framework may extend to other marginalized families (e.g., adoptive families, multiracial families) with consideration of sociocultural and historical contexts. With a strengths‐based approach, we synthesize social science scholarship (with a focus on psychological, developmental, and family science) related to marginalized family identity and associated outcomes. Here, we emphasize marginalized family processes and individual outcomes beyond typical developmental ones. We describe the utility and promise of MFIT for future research, as well as implications for practice and policy relevant to marginalized families.
