AI Article Synopsis

  • - A new tool called the teen COVID-19 Vaccine Hesitancy Scale (tVHS-COVID) was developed to assess vaccine hesitancy specifically among adolescents and their parents, addressing a gap in existing research. - The study involved a nationally representative survey with 764 parent-teen pairs, where exploratory and confirmatory factor analyses were conducted, confirming a three-factor structure with strong reliability for both adolescents and parents. - Results showed that higher tVHS-COVID scores correlated with a lower willingness to receive the COVID-19 vaccine, highlighting the importance of tracking vaccine hesitancy in adolescents as they begin to take more active roles in healthcare decisions.

Article Abstract

Background: Vaccine hesitancy is an urgent public health threat. While tools have been developed to monitor vaccine hesitancy among parents and the general adult population, no such tool exists for adolescents.

Methods: We modified an existing adult Vaccine Hesitancy Scale to create a teen COVID-19 Vaccine Hesitancy Scale (tVHS-COVID) for adolescents and their parents. To validate our scale, we conducted a nationally representative survey of 764 parent-teen dyads. We performed exploratory factor analysis (EFA) to determine the factor structure followed by confirmatory factor analysis (CFA) to test the factor structure validity using two random subsets. We evaluated internal consistency by Cronbach alpha values and construct validity by comparing tVHS-COVID scores to intention to receive future COVID-19 doses.

Results: EFA suggested a three-factor structure with 13-items. CFA indicated good fit for adolescents (CFI = 1.00; RMSEA = 0.023; SRMR = 0.062; NNFI-TLI = 0.998) and for parents (CFI = 1.00, RMSEA = 0.031; SRMR = 0.028; NNFI-TLI = 1.00). Internal consistency exceeded 0.79 for adolescents and 0.78 for parents. As tVHS-COVID scores increased, the percent of adolescent and parent respondents who reported they were willing to receive a COVID-19 vaccine decreased.

Discussion: The tVHS-COVID offers a unique tool that can be used to monitor COVID-19 vaccine hesitancy among adolescents and their parents. As adolescents take on more proactive roles in medical decision-making, monitoring vaccine hesitancy among this population becomes increasingly important.
