Adherence to Timely Vaccinations in the United States.
Abstract: To estimate 1) the proportion of children not adhering to the Advisory Committee on Immunization Practices (ACIP) recommended early childhood immunization schedule and 2) associations between schedule adherence, sociodemographic characteristics and up-to-date immunization status by 19-35 months of age. Methods: We used 2014 National Immunization Survey (NIS) provider-verified vaccination data to classify vaccination patterns as “recommended” (i.e., in line with ACIP dose- and agespecific recommendations), “alternate” (i.e., in line with either limiting the number of shots per visit or skipping at least one vaccine series) or “unknown/unclassifiable” (i.e., not in-line with ACIP recommendations nor clearly limiting shots per visit or vaccine series). We evaluated predictors of immunization schedule adherence patterns and estimated the association between vaccination patterns and up-to-date status for all ACIP-recommended vaccinations (including rotavirus and hepatitis A vaccines) using Poisson regression. Results: The majority of children’s patterns were classified as “recommended” (63%), with 23% and 14% following alternate or unknown/unclassifiable patterns, respectively; 58% of children were up-to-date with all ACIP-recommended immunizations by 19-35 months. Not being up-to-date was associated with alternate (prevalence ratio [PR] = 4.2, 95% confidence interval [CI] 3.9, 4.5) and unknown/unclassifiable (PR = 2.4, 95% CI 2.2, 2.7) vaccination patterns. Conclusion: Overall high vaccine coverage by 19-35 months of age may miss non-adherence to the recommended immunization schedule in the first 18 months of life, leaving children vulnerable to preventable diseases. With more than one-third of US children not following the ACIP schedule, targeted interventions are needed to minimize vaccine delays and disease susceptibility.
Beyond Fear Appeals: The Role of Hope in Improving Effectiveness of Health Messages.” Paper accepted for poster by Communicating Science, Health, Environment, and Risk Division
Abstract: One of the understudied areas in health communication research is hope. This study examines the effect of efficacy-inducing information on hope and subsequent attitudinal health behaviors. A total of five hundred fifty-three adults in the United States read health promotion social media posts designed to induce perceived self-efficacy (vs. non-efficacy-inducing health information) in fear-appeal […]

Effective Health Risk Communications: Lessons Learned about COVID-19 Pandemic through the Lens of Practitioners
Abstract: The study utilizes semi-structured interviews of health risk communication practitioners in the backdrop of the COVID-19 pandemic. The contingency theory of strategic conflict management is the guide to understanding the challenges and nuances. Insights gained from interviewing practitioners (projected, n=40) from different sectors with diverse professional backgrounds will help advance the contingency theory’s application […]
