Gender-based power dynamics within intimate relationships such as controlling behaviours are driven by inequitable gender norms that perpetuate intimate partner violence (IPV). Yet, the ways in which we understand and measure gender-based power dynamics focus on the relationships of monogamous, cisgender, white, heterosexual women. This paper outlines our process of planning and implementing a qualitative, youth-led, community-based research (CBR) study exploring how diverse youth with intersecting identities perceive existing measures of gender equity and understand gender equity based on their own relationships. Between August-November 2022, we used purposive sampling to recruit 30 gender-inclusive young women and non-binary youth aged 17–29 with diverse identities, who live in British Columbia (BC), and have recent experience in a non-heterosexual and/or non-monogamous relationship (within prior 12 months). Using CBR methods, we hired and trained three Youth Research Associates (YRAs) and convened a 10-member Youth Advisory Committee (YAC) comprised of youth aged 19–28 years with queer, trans, and/or non-monogamous identities and experiences to consult on all aspects of our study. YRAs conducted cognitive interviews using an interview guide co-developed and piloted in partnership with the YAC and YRAs. Cognitive interviews explored youth perceptions of gender equity and two gender equity measures widely used in health research today. Interview data will be analyzed collaboratively using intersectional descriptive and thematic analysis. Results from our CBR study will be used to make recommendations to advance gender equity measurement to be more inclusive of and applicable to a diversity of youth relationships, experiences, and identities.
