Abstract:
Introduction: An emerging literature documents substantial mental-health disparities by sexual orientation amongst adolescents, with sexual-minority youth exhibiting poorer mental health than heterosexual youth. This brief report provides the first empirical account of how the association between sexual-minority status and adolescent mental health differs depending on who assesses adolescents' mental health (child/mother/father/teacher), and how informant discrepancies in assessments of adolescent mental health differ by adolescents’ sexual orientation. Methods: Data come from an Australian national sample of 14-/15-year-old adolescents (Longitudinal Study of Australian Children; n~3,000). Adolescent mental health is measured using multiple measures from the Strengths and Difficulties Questionnaire, and modelled using multivariable linear regression models. Results: Mental-health disparities between sexual-minority and heterosexual adolescents emerged irrespective of who assessed the child's mental health. However, their magnitude varied substantially by informant, being largest when mental-health was reported by adolescents (~0.7 standard deviations) and smallest when reported by teachers (~0.2 standard deviations). Discrepancies between mental-health scores collected from the child and other informants were largest for internalising than externalising behaviours, and in child-father than child-mother comparisons. Conclusions: Understanding informant discrepancies and their meaning is pivotal to designing surveys that generate robust insights into the health of sexual-minority adolescents, as well as appropriate policy interventions.
