Dispositional Authenticity, Internalized Homonegativity, and Relationship Quality in Same-Gender Couples: An Actor-Partner Interdependence Moderation Model

This dyadic study with 158 same-gender couples examined the relationships between dispositional authenticity, internalized homonegativity, and perceived relationship quality, introducing The Internalized Homonegativity-Authenticity Interaction Theory. Internalized homonegativity was found to moderate the relationships between external aspects of dispositional authenticity and perceived relationship quality within same gender couples. Individuals’ authentic living was only positively related to their own perceived relationship quality when their partners experience below-average levels of internalized homonegativity. The relationship between individuals’ accepting external influence and their partners’ perceived relationship quality was negative when they experience above-average levels of internalized homonegativity. Different aspects of
authenticity interact with internalized homonegativity in unique ways. Negative self beliefs stemming from external environments could alienate internal authenticity. The level of external influence and inclusivity within an environment may shape the diverse development trajectories of LGB individuals’ perception of their social group, resulting in varying outcomes for their attitudes and beliefs towards the group. Furthermore, behavioural or relational authenticity is not always positive; it may contribute to lower relationship quality when one’s partner harbours homonegative beliefs. This study highlights the complex interplay between authenticity, internalized homonegativity, and relationship quality, with significant implications for future research and action.
