Victoria Clarke's research primarily examines the psychological well-being of heterosexual couples, particularly in the context of marriage.

Victoria Clarke does not focus mainly on heterosexual couples’ psychological well‑being in marriage. Her work is mainly about sexual and gender identity, looking at how people understand and live out their identities. She studies how people’s experiences of gender and sexuality shape their mental health and social interactions. For example, she has researched how transgender people navigate stigma and support systems. Thus, her research interests lie in gender and sexuality rather than marital well‑being.
