abstract="BACKGROUND: An important issue in alcohol and drug use research is the degree to which study participants cooperate with survey interviewers and provide accurate information. We examine the year-by-year trends in the perceived cooperativeness of participants in a large national survey focused on alcohol and drug use in the United States between 2002 and 2015. <br><br>METHODS: We examine fourteen years of cross-sectional data (2002-2015) from the National Survey on Drug Use and Health (NSDUH) using the NSDUH's Restricted Data Analysis System. The main variable of interest was field interviewer reported participant cooperativeness (i.e., &quot;How cooperative was the respondent?&quot;). We present estimates of proportional rates of cooperation and examine the degree to which the estimated proportions for cooperativeness vary from 2002 to 2003 estimates based on non-overlapping 95% confidence intervals as a proxy for secular trend tests. <br><br>RESULTS: The proportion of respondents classified as &quot;very cooperative&quot; was consistently elevated in all survey years, increasing significantly from 95.6% (CI = 95.4-95.8) in 2002-2003 to 96.7% (CI = 96.5-96.8) in 2014-2015. Elevated levels of cooperation were observed for participants reporting no/any past-year alcohol, marijuana, cocaine, and heroin use. Rates were elevated-96 to 98% in 2014-2015-among respondents of all sociodemographic backgrounds (i.e., age, gender, race/ethnicity, income, nativity). Only a fraction of participants were classified as &quot;not very cooperative&quot; (0.2-0.4%) or &quot;openly hostile&quot; (0.1%). <br><br>CONCLUSIONS: Cooperativeness with NSDUH survey research has been very high since the early 2000s with perceived participant cooperativeness increasing in recent years and consistently low rates of non-cooperativeness across all years.<br><br>Copyright © 2019.
