abstract="BACKGROUND AND AIMS: Including a low-intensity blood collection method in population-based alcohol studies would advance our ability to study biological mechanisms related to alcohol. However, the likelihood of participation in such a blood collection method remains understudied. This study's primary aims were to (1) estimate the return rate of mail-in, self-administered dried blood spot (saDBS) samples in national surveys and (2) test correlates of returning a sample. <br><br>DESIGN: Re-contact of all eligible participants from two telephone, population-based alcohol surveys followed by chi-square tests and multivariate logistic regression analysis. SETTING: Non-institutionalized U.S. population in all 50 states and Washington, D.C. PARTICIPANTS: Adults aged 18+ who reported drinking at least one alcoholic beverage in the past 12 months (assessed 2017-2018). Contact was made with 680 eligible participants, and 257 consented. MEASUREMENTS: The return rate of saDBS samples was defined as the proportion of returned samples among those who were eligible and contacted. Key correlates examined were gender, age, race/ethnicity, and education. <br><br>FINDINGS: Among the 680 eligible people contacted, 179 (26.3%) returned a saDBS sample. Blacks (OR = 0.60, 95% CI = 0.37-0.98), Latinos (OR = 0.41, 95% CI = 0.23-0.71) and those with a high school education or less (OR = 0.49, 95% CI = 0.31-0.79) were less likely to return a saDBS sample. <br><br>CONCLUSIONS: The likelihood of participating in mail-in, self-administered dried blood spot (saDBS) sampling among drinkers in the U.S. general population appears low, and Blacks, Latinos, and people with lower levels of education appear less likely to provide a saDBS sample compared with Whites and people with higher levels of education.<br><br>This article is protected by copyright.
