The National Immunization Survey-Adult COVID Module (NIS-ACM) and National Immunization Survey-Child COVID Module (NIS-CCM) are random-digit dialing cellular telephone surveys of households, sponsored by the CDC, used to generate weekly and monthly COVID-19 attitudinal measures for adults 18 years and older and children 6 months to 17 years. This paper discusses the use of small area estimation models and methods to generate estimates by state for 5 to 17-year-old children for key attitudinal measures (as reported by the parent or guardian) including vaccination status and intent, COVID-19 vaccine safety, importance of getting vaccinated, and mask wearing in past seven days. Cross-sectional, bivariate, and time-series small area models (i.e., linear mixed models) were used to combine (a) direct survey estimates from the NIS-CCM, (b) direct survey estimates from the NIS-ACM, and (c) regression estimates based on auxiliary data sources.
