Abstract:
|
MEPS is a complex sample survey sponsored by the Agency for Healthcare Research and Quality (AHRQ). Its sample is drawn from respondents to the previous year's National Health Interview Survey (NHIS). The MEPS, like most sample surveys, experiences unit nonresponse. Therefore, the base weight of MEPS respondents is adjusted to compensate for nonresponse. The first level adjustment is at the dwelling unit (DU) level to account for nonresponse among those households subsampled from NHIS for the MEPS. The adjustment is done using socio-economic, demographic, and health variables. Response propensity scores based on various combinations of covariates are calculated and quintiles of propensity scores are used to adjust the MEPS base weights for the assessment. This paper examines the impact on the DU level nonresponse weight adjustment with and without inclusion of health variables.
