Per the UNAIDS 90–90–90 target, 81% of people living with HIV should receive medication. However, numerous previous studies focused on adherence rather than the initial healthcare seeking intention if diagnosed with HIV (HIV HSI). Based on the Theory of Planned Behavior (TPB), anonymous online survey data were collected from December 2016 through February 2017 from 2709 young MSM (YMSM) ages 15–39. Multivariate logistic regression found the significant factors and strengths of associations with HIV HSI varied by their HIV voluntary counseling and testing (VCT) experience. YMSM without VCT experience perceiving high support from salient others (AOR = 1.28) and high control under facilitating conditions (AOR = 2.73) had higher HIV HSI. YMSM with VCT experience perceiving high control under facilitating (AOR = 1.79) and constraining (AOR = 1.54) conditions had higher HIV HSI. Regardless of VCT experience, YMSM with positive attitudes toward positive healthcare seeking outcomes (AOR = 3.72–3.95) had highest HIV HSI, highlighting the importance of increasing positive outcome expectations in YMSM. ? 2018, Springer Science+Business Media, LLC, part of Springer Nature.EnglishHealthcare seeking intention if diagnosed with HIV (HIV HSI); HIV voluntary counseling and testing (VCT); HIV/AIDS; Taiwan; Theory of Planned Behavior (TPB); Young men who have sex with men (YMSM)[SDGs]SDG3article; counseling; diagnosis; expectation; human; Human immunodeficiency virus; men who have sex with men; nonhuman; Taiwan; Theory of Planned Behavior; adolescent; adult; behavior; comparative study; Human immunodeficiency virus infection; male; male homosexuality; patient attitude; psychology; serodiagnosis; sexual counseling; Taiwan; young adult; Adolescent; Adult; AIDS Serodiagnosis; HIV Infections; Homosexuality, Male; Humans; Intention; Male; Patient Acceptance of Health Care; Sex Counseling; Taiwan; Young AdultHealthcare Seeking Intention if Diagnosed with HIV Among Young MSM in Taiwan: A Theory-Based Comparison by Voluntary Counseling and Testing Experiencejournal article10.1007/s10461-018-2169-3298082582-s2.0-85047659383
