Innovative Sampling Methods to Generate Representative Asian American, Native Hawaiian, and Pacific Islander Health Data
Objective/Purpose: This study assessed the feasibility of an alternative approach for population-level surveillance in a large yet understudied Asian subgroup (South Asians). Time-location sampling depends on enumeration and weighting of venues where the priority population congregates, generated by qualitative inquiry. Selected units, and potential respondents with each unit, were randomly sampled.
Methods: Qualitative methods were utilized to generate a sampling frame of venues where South Asians congregate, along with specific days/times where high volumes of community members were present. Using randomization methods, a pre-specified number of time-location sampling units were selected within a 30 day period. Within each unit, individuals were systematically sampled and invited to complete a tobacco use survey. Consenting participants were able to complete a paper survey or provide responses via electronic tablet, and provided a $5.00 incentive upon completion.
Results: Findings indicated time-location sampling generated high response rates among South Asians for tobacco surveillance (90+%). Community-based outreach was paramount in ensuring research was able to be conducted at randomly-selected venues without interference. Success was dependent on a relatively large and diverse data collection team, to allow concordance with potential respondents. U.S.-born South Asians preferred electronic surveys while immigrants tended to request paper surveys.
Discussion/Conclusion: This feasibility test provides proof-of-principle that time-location sampling can be utilized in large Asian American subgroup to collect health behavior data. Analyses are being conducted to determine if this probabilistic sampling method generates representative population-level data and is comparably feasible among other racial/ethnic minorities.
