Self-injury among trans individuals and matched controls: prevalence and associated factors

This study aims to determine the prevalence rate of current non-suicidal self-injury (NSSI) among trans individuals, in comparison with a control sample of non-trans adults. It also aims to compare those with current NSSI and those with no history of NSSI in terms of psychological well-being, self-esteem, body dissatisfaction, social support and demographic factors. Participants were 97 adults, diagnosed with transsexualism (ICD-10, F64.0), attending a national gender clinic in the United Kingdom, and a matched control group. Clinical participants were all engaged on the treatment pathway. Participants completed the following self-report measures: Self-Injury Questionnaire - Treatment Related (SIQ-TR), Symptom Checklist 90 Revised (SCL-90-R), Rosenberg Self-Esteem Scale (RSE), Hamburg Body Drawing Scale (HBDS) and Multidimensional Scale of Perceived Social Support (MSPSS). The results showed that the trans participants had a significantly higher prevalence of current NSSI behaviour than the non-trans group, with 19% currently engaging in NSSI. Current NSSI was also significantly more prevalent among trans men than trans women. Compared with both trans and non-trans participants with no history of NSSI, trans participants with current NSSI had significantly higher scores on SCL; significantly lower scores on RSE, HBDS and MSPSS; and were younger in age. The study concludes that trans men, specifically, are more at risk of NSSI than trans women and the general population, even when on the treatment pathway. Those who currently self-injure have greater psychopathology, lower body satisfaction, lower self-esteem, lower social support and tend to be younger, than those who do not engage in NSSI.
