Mental Health Provider Training to Improve LGBTQ Competence and Reduce Implicit and Explicit Bias: A Randomized Controlled Trial of Online and In-Person Delivery

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals in most countries face strong stigma and often rely on affirmative mental health care to foster coping and resilience. We tested an LGBTQ-affirmative mental health training for psychologists and psychiatrists by comparing in-person versus online modalities and the added benefit of supervision. Participants were randomized to a two-day training either in-person (n = 58) or via live-stream online broadcast (n = 55). Outcomes were assessed at baseline and 5, 10, and 15 months posttraining. Optional monthly online supervision was offered (n = 47) from months 5 to 15. Given the substantial need for LGBTQ-affirmative expertise in high-stigma contexts, the training took place in Romania, a Central-Eastern European country with some of the highest LGBTQ stigma in Europe. Participants (M age = 35.1) were mostly cisgender female (88%) and heterosexual (85%). Trainees, regardless of whether in-person or online, reported significant decreases from baseline to 15-month follow-up in implicit and explicit bias and significant increases in LGBTQ-affirmative clinical skills, beliefs, and behaviors. LGBTQ-affirmative practice intentions and number of LGBTQ clients did not change. Participants who attended at least one supervision session demonstrated greater reductions in explicit bias and increases in LGBTQ-affirmative behaviors from baseline to 15-month follow-up than participants who did not attend supervision. LGBTQ-affirmative mental health training can efficiently and sustainably improve LGBTQ competence and reduce provider bias in high-stigma contexts. Future research can identify additional ways to encourage mental health providers' outreach to LGBTQ clients in need of affirmative care. Public Significance Statement This study provides initial evidence that LGBTQ-affirmative mental health trainings can improve providers' LGBTQ competence and reduce their bias, with sustained effects across time. The fact that online training showed similar effects as in-person training paves the way for efficient dissemination of such training, including in high-stigma global contexts.
