AFFIRM Online: Utilising an Affirmative Cognitive–Behavioural Digital Intervention to Improve Mental Health, Access, and Engagement among LGBTQA+ Youth and Young Adults

Digital mental health interventions may enable access to care for LGBTQA+ youth and young adults that face significant threats to their wellbeing. This study describes the preliminary efficacy of AFFIRM Online, an eight-session manualised affirmative cognitive behavioural group intervention delivered synchronously. Participants (M(age) = 21.17; SD = 4.52) had a range of sexual (e.g., queer, lesbian, pansexual) and gender (e.g., non-binary, transgender, cisgender woman) identities. Compared to a waitlist control (n = 50), AFFIRM Online participants (n = 46) experienced significantly reduced depression (b = −5.30, p = 0.005, d = 0.60) and improved appraisal of stress as a challenge (b = 0.51, p = 0.005, d = 0.60) and having the resources to meet those challenges (b = 0.27, p = 0.059, d = 0.39) as well active coping (b = 0.36, p = 0.012, d = 0.54), emotional support (b = 0.38, p = 0.017, d = 0.51), instrumental support (b = 0.58, p < 0.001, d = 0.77), positive framing (b = 0.34, p = 0.046, d = 0.42), and planning (b = 0.41, p = 0.024, d = 0.49). Participants reported high acceptability. This study highlights the potential of digital interventions to impact LGBTQA+ youth mental health and explores the feasibility of digital mental health to support access and engagement of youth with a range of identities and needs (e.g., pandemic, lack of transportation, rural locations). Findings have implications for the design and delivery of digital interventions for marginalised youth and young adults.
