PrEParing for NextGen: Cognitive Interviews to Improve Next Generation PrEP Modality Descriptions for Young Men Who have Sex with Men.

Next generation PrEP formulations may circumvent factors that impede daily oral pre-exposure prophylaxis (PrEP) use among young men who have sex with men (YMSM). We conducted video-based cognitive interviews with 20 YMSM (age 16-24) recruited in the US Northeast to assess participants' attitudes and comprehension of written descriptions of next generation PrEP modalities. Participants were predominately racial/ethnic minorities and half used daily oral PrEP. We identified four main areas for improvement of descriptions: defining scientific terms and balancing medical jargon and casual language; referencing more established products to contextualize PrEP formulations (e.g., hormonal implants); ensuring clarity and reducing redundancy; and including imagery (e.g., rectal douche applicator). The refined descriptions serve as exemplar text that may be used in future studies examining YMSM's preferences across next generation PrEP modalities. Accurate descriptions of next generation PrEP products strengthen measurement accuracy and can help roll-out products that become approved for clinical use.
