We assessed whether videos with medical footage of organ preservation and transplantation plus sad, unresolved, or uplifting stories differentially affect deceased organ donor registration among clients in Latinx-owned barbershops and beauty salons. In a 2 × 3 randomized controlled trial, participants (N = 1,696, mean age 33 years, 67% female) viewed one of six videos. The control portrayed a mother who received a kidney (uplifting), excluding medical footage. Experimental videos included medical footage and/or showed a mother waiting (unresolved) or sisters mourning their brother's death (sad). Regression models assessed relative impact of medical footage and storylines on: (1) registry enrollment, (2) donation willingness stage of change, and (3) emotions. Randomization yielded approximately equal groups relative to age, sex, education, religion, nativity, baseline organ donation willingness, beliefs, and emotions. Overall, 14.8% of participants registered. Neither medical footage, sad, nor unresolved stories differentially affected registration and changes in organ donation willingness. Sad and unresolved stories increased sadness and decreased positive affect by ~0.1 logits compared with the uplifting story. Educational videos about organ donation which excluded or included medical footage and varying emotional valence of stories induced emotions marginally but did not affect viewers' registration decisions differently. Heterogeneity of responses within video groups might explain the attenuated impact of including medical footage and varying emotional content. In future work, we will report qualitative reasons for participants' registration decisions by analyzing the free text responses from the randomized trial and data from semistructured interviews that were conducted with a subset of participants.
