Of participants, 66.5% met PrEP eligibility criteria, 53.7% expressed willingness to use LAI-PrEP within 6 months, and 77.9% were PrEP na\u00efve. Current oral PrEP users showed higher LAI-PrEP willingness (adjusted odds ratio [AOR] = 2.23, 95% CI [1.44, 3.44]) than the PrEP na\u00efve group. Condomless anal intercourse (AOR = 1.32, 95% CI [1.08, 1.61]) and recent sexually transmitted infection diagnosis (AOR = 1.84, 95% CI [1.15, 2.95]) were positively associated with willingness. Structural equation modeling revealed distinct predictors: for PrEP na\u00efve group, LAI-PrEP willingness was influenced by outcome expectancies, HIV risk perception, self-efficacy, and subjective norms (p &lt;.05), while the PrEP-experienced group relied more on outcome expectancies. Tailored interventions addressing group-specific cognitive factors are critical to optimize LAI-PrEP adoption.<\/jats:p>","DOI":"10.1521\/aeap.2025.37.6.427","type":"journal-article","created":{"date-parts":[[2025,12,22]],"date-time":"2025-12-22T17:38:51Z","timestamp":1766425131000},"page":"427-442","source":"Crossref","is-referenced-by-count":3,"title":["PrEP-Related
