A mixed-methods randomized controlled trial pilot study evaluated an educational curriculum focused on the medical needs of transition-age youth (TAY) with autism (ASD) for family nurse practitioner students. Fourteen out of a cohort of 16 (87.5%) nursing students consented to participate in the study and were randomly assigned to either a waitlist control group (WLC) (n = 8) or an intervention group (INT) (n = 6). Three measures were used to determine pre- and post-intervention levels of self-efficacy, knowledge, and attitudes. Quantitative and qualitative data provide preliminary support that participation in intervention may improve and enhance knowledge and level of self-efficacy in working with TAY with ASD.
