Men who have sex with men (MSM) who take PrEP tend to report reduced condom use, but little is known about the underlying mechanisms. For this study, MSM who take PrEP (i.e., PrEP experienced; <jats:italic>n<\/jats:italic>\u2009=\u200988) and MSM who do not (i.e., PrEP na\u00efve; <jats:italic>n<\/jats:italic>\u2009=\u2009113) completed an online study, including the condom purchase task (CoPT). The CoPT assesses decisions to purchase condoms across escalating prices (range: free\u2013$55) for sex with different types of hypothetical partners: those least likely to have an STD (least STD) and those that participants most want to have sex with (most want sex with). When condoms were free, PrEP\u2010experienced MSM had a lower rate of condom purchasing than did PrEP\u2010na\u00efve MSM. For both partner types, PrEP\u2010experienced MSM reached a price break point (i.e., would not buy condoms) at a lower price than did PrEP\u2010na\u00efve pariticipants. For the most\u2010want\u2010sex\u2010with partner at the price at which participants elected not to buy condoms, only 23% of PrEP\u2010experienced MSM chose to abstain from sex when not purchasing condoms versus 53% among PrEP\u2010na\u00efve MSM. Similar patterns were observed for the least\u2010STD partner. The results support the potential utility of the CoPT in identifying behavioral mechanisms related to condom use and PrEP.<\/jats:p>","DOI":"10.1002\/jeab.905","type":"journal-article","created":{"date-parts":[[2024,2,15]],"date-time":"2024-02-15T07:48:37Z","timestamp":1707983317000},"page":"233-245","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Use of preexposure prophylaxis and condom purchasing decisions"],"prefix":"10.1002","volume":"121","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9335-2667","authenticated-orcid":false,"given":"Nioud Mulugeta","family":"Gebru","sequence":"first","affiliation":[{"name":"Center for Alcohol and Addiction Studies, Department of Behavioral and Social Sciences Brown University School of Public Health  Providence RI USA"},{"name":"Department of Health Education and Behavior University of Florida  Gainesville FL USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justin C.","family":"Strickland","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences Johns Hopkins University School of Medicine  Baltimore MD USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5854-3425","authenticated-orcid":false,"given":"Derek D.","family":"Reed","sequence":"additional","affiliation":[{"name":"Institutes for Behavior Resources, Inc.
