Background: Nonmedical prescription opioid (NMPO) use is a problem among young adults, yet young NMPO users are a diverse population that has been challenging to engage in overdose prevention and harm reduction programs.
Objectives: This study compared the effectiveness and characteristics of persons recruited through two different sampling strategies to inform research and intervention efforts with young adult NMPO users.
Methods: We analyzed data from the Rhode Island Young Adult Prescription Drug Study (RAPiDS), which enrolled persons aged 18 to 29 who reported past 30-day NMPO use. We compared the characteristics of two samples recruited simultaneously between February 2015 and February 2016. One sample was recruited using field-based strategies (e.g., respondent-driven sampling, transit ads), and a second from internet sources (e.g., online classifieds).
Results: Among 198 eligible participants, the median age was 25 (IQR: 22, 27), 130 (65.7%) were male, 123 (63.1%) were white, and 150 (78.1%) resided in urban areas. A total of 79 (39.9%) were recruited using field-based strategies and 119 (60.1%) were recruited from internet sources. Internet-recruited persons were younger (median = 24 [IQR: 21, 27] vs. 26 [IQR: 23, 28] years) and more likely to reside in rural areas (16.2% vs. 5.3%), although this finding was marginally significant. Field-recruited participants were more likely to have been homeless (36.7% vs. 17.7%), have been incarcerated (39.7% vs. 21.8%), and engage in daily NMPO use (34.6% vs. 14.5%).
Conclusions: Multipronged outreach methods are needed to engage the full spectrum of young adult NMPO users in prevention and harm reduction efforts.
