Introduction: Internalised homophobia has been associated with maladaptive coping and higher levels of psychological distress. Self-harm within a lesbian population isunder researched, specifically in relation to internalised homophobia. The study aimed to determine whether internalised homophobia is a predictor of self-harm in lesbians. Method: All participants (N = 148) were over 18, assigned female at birth, and identified as lesbian. Participants completed the self-report questionnaire online. The study implemented a mixed method design comprised of a cross-sectional correlational design and a qualitative design. Results: A Pearson r correlation identified an insignificant weak, positive relationship between IH and self-harm. A simple linear regression identified depression as a significant predictor of self-harm. Through thematic analysis three themes were identified: influence of sexuality on self-harm, importance of (L)GBTQ+ community, and negative societal perceptions. Conclusion: Internalised homophobia is not a predictor of self-harm in lesbians. However, through thematic analysis, internalised homophobia was identified as a subtheme of self-harming behaviours. The strengths and limitations of the study are addressed alongside suggestions for future research.
