The objective of this study was to assess monetary and non-monetary factors that can influence the decision to participate in a future health survey. A questionnaire was administered to eligible, low-income participants (n = 1502) of the 2012 Los Angeles County Health and Nutrition Examination Survey (LAHANES-II). Multivariable regression analyses were performed to describe factors potentially associated with future intent to participate in similar survey designs. The results of the survey suggest that, overall, female participants had a greater interest in participating under a variety of incentive scenarios. Compared to the 25–34 age group, older participants (35–44, 45–84) reported more interest to participate if $10 cash [prepaid gift/debit card], a coupon for product/travel, or a small item [e.g., granola bar, t-shirt, pen] was offered, whereas younger participants (18–24) reported greater interest for $25 cash or a coupon for product/travel. Non-Whites, when compared to Whites/Non-Hispanics, reported greater interest to participate if any of the incentives was offered. High school graduates, when compared to those with some college education, reported greater interest to participate if $10 cash, a small item, or a lottery ticket was offered. Presence of two or more chronic conditions increased interest while concerns about participation in LAHANES-II was associated with reduced interest to participate in future health-related surveys. The results suggest that both incentives and non-monetary considerations (e.g., personal concerns about participating and individual level characteristics) can influence the decision to participate in health-related surveys and offer insights into strategies that can improve response rates for these assessments that are often used to inform community planning.
