College students are particularly vulnerable at this critical life juncture as transitioning to adulthood may impact emotional health and well-being, contributing to anxiety, depression, and feelings of hopelessness, all of which are linked to increased risk of substance use and disorders. Objective: This study characterizes the design and status of the MAPme Project, a prospective project centered on substance use and emotional wellness during and beyond college. Herein, we describe the 2018\u20132024 pilot cohort that was followed during the first two years of college, remotely during the COVID-19 pandemic, and upon the return to campus. We also describe our latest 2025+ cohort with ongoing data collection. Participants: The 2018\u20132024 cohort comprised 301 college freshmen who completed online assessments at baseline (Wave 1). The 2025+ cohort has currently enrolled 618 students and counting. Methods: We provide descriptive information on both cohorts, along with preliminary associations of pre- and early collegiate substance use outcomes, psychopathology, sleep patterns, and personality traits. Results: Approximately 64% of first-year students reported use of a substance in the 90 days leading up to college in 2018. Alcohol and cannabis were the most prevalent substances used in both cohorts with males consuming more alcohol than females. Females reported greater levels of daily stressors and mood symptoms. Other health and personality characteristics and observed associations between psychosocial risk and protective factors are described. Prior studies demonstrate the ability to test research hypotheses in the social, health, and clinical areas of psychology with robust statistical power. Conclusions: Substance use and emotional well-being vary considerably upon entry into college\/university and at any particular moment in time. The MAPme Project encourages the engagement of students to address challenges associated with lack of awareness, inclusivity, and acceptance of scientific research. Overcoming barriers of inclusivity and empowering the community is key to the successful adoption and implementation of campus health and community-oriented research programs and systematically enhancing research training.<\/jats:p>","DOI":"10.3390\/ijerph23081084","type":"journal-article","created":{"date-parts":[[2026,8,20]],"date-time":"2026-08-20T08:10:20Z","timestamp":1787213420000},"page":"1084","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The MAPme Project: Implementing a College-Based Study of Substance Use and Mental Wellness"],"prefix":"10.3390","volume":"23","author":[{"given":"Whitney L.","family":"Barfield-Steward","sequence":"first","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8926-0236","authenticated-orcid":false,"given":"Yijin","family":"Xiang","sequence":"additional","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dalora","family":"Najera","sequence":"additional","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jenipher","family":"Ober-Oluoch","sequence":"additional","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chelsie","family":"Benca-Bachman","sequence":"additional","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"},{"name":"Department of Psychiatry and Human Behavior, Brown University, Providence, RI 02906, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hope","family":"Derricott","sequence":"additional","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rameez","family":"Syed","sequence":"additional","affiliation":[{"name":"Behavioral Genetics of Addiction Laboratory, Department of Psychology, Emory University, Atlanta, GA 30322, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6418-744X","authenticated-orcid":false,"given":"Justine W.","family":"Welsh","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences, School of Medicine, Emory University, Atlanta, GA 30329, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6809-9962","authenticated-orcid":false,"given":"Rohan H.
