Abstract
BACKGROUND
Large gaps exist in research on alcohol use and intimate partner aggression (IPA) among sexual minority women (SMW; eg, lesbian, bisexual). Dyadic research with SMW and their partners can illuminate how couple-level factors operate in conjunction with individual-level factors to shape well-being in this understudied and vulnerable population. Given the traditionally gendered lens with which women are primarily viewed as victims and men as perpetrators, understanding the dynamics of IPA in same-sex female couples can also advance research and practice related to IPA more generally.
OBJECTIVE
Guided by a recent extension of the minority stress model that includes relational (couple-level) sexual minority stress and the I-cubed theoretical perspective on IPA, we will collect individual and dyadic data to better characterize the links between hazardous drinking and IPA among SMW and their partners. First, this study aims to examine the associations among minority stress, hazardous drinking, and IPA in SMW and their partners. Minority stressors will be assessed as both individual and couple-level constructs, thus further extending the minority stress model. Second, we aim to examine potential mediators and moderators of the associations among minority stress, hazardous drinking, and IPA. Finally, we aim to test models guided by the I-cubed theoretical perspective that includes instigating (eg, relationship conflict), impelling (eg, negative affect and trait anger), and inhibiting (eg, relationship commitment and emotion regulation) or disinhibiting (eg, hazardous drinking) influences on IPA perpetration.
METHODS
This United States National Institutes of Health-funded project will draw from a large and diverse cohort of SMW currently enrolled in the Chicago Health and Life Experiences of Women (CHLEW) study-a 21-year longitudinal study of risk factors and consequences associated with SMW hazardous drinking. SMW currently enrolled in the CHLEW and their partners will be invited to participate in the CHLEW Couples Study. By analyzing dyadic data using actor-partner interdependence models, we will examine how each partner's minority stress, hazardous drinking, and IPA experiences are associated with both her own and her partner's minority stress, hazardous drinking, and IPA perpetration.
RESULTS
Data collection began in February 2021 and will likely continue through 2023. Initial results should be available by mid-2024.
CONCLUSIONS
The CHLEW Couples Study will fill important gaps in knowledge and provide the basis for future research aimed at clarifying the causal pathways linking hazardous drinking and IPA among SMW. This will support the development of culturally appropriate targeted individual and dyadic prevention and intervention strategies.
