【 摘 要 】

BackgroundHandwashing with soap and water is an important way to prevent transmission of viruses and bacteria and worldwide it is estimated handwashing can prevent 1 in 5 viral respiratory infections. Frequent handwashing is associated with a decreased risk for infection with SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19). Using a hand sanitizer with at least 60% alcohol when handwashing is not feasible can also help prevent the transmission of viruses and bacteria.ObjectiveSince early 2020, the public has been encouraged to handwash frequently with soap and water and use alcohol-based hand sanitizer when soap and water are not available to reduce COVID-19 transmission. This study’s objectives were to assess U.S. adults’ perceptions of components of the Capability, Opportunity, Motivation and Behavior (COM-B) Model in relation to these two hand hygiene behaviors and to identify relationships between these components and hand hygiene behaviors.MethodsItems assessing capability, opportunity, motivation, and hand hygiene behaviors were included in FallStyles, a survey completed by 3,625 adults in the fall of 2020 through an online panel representative of the U.S. population. We calculated composite capability, opportunity, and motivation measures and descriptive statistics for all measures. Finally, we conducted multiple logistic regressions to identify predictors of handwashing and hand sanitizer use.ResultsMost respondents reported frequently washing hands with soap and water (89%) and using alcohol-based hand sanitizer (72%) to prevent coronavirus. For capability, over 90% of respondents said that neither behavior takes a lot of effort, but fewer agreed that they knew when, or how, they should engage in handwashing (67%; 74%) and hand sanitizer use (62%; 64%). For opportunity, over 95% of respondents said lack of time didn’t make it hard to engage in either behavior; fewer said visual cues reminded them to engage in the behaviors (handwashing: 30%; sanitizer use: 48%). For motivation, the majority believed the two behaviors were good ways to prevent coronavirus illness (handwashing: 76%; sanitizer use: 59%). Regressions indicated that capability, opportunity, and particularly motivation were positively associated with both hand hygiene behaviors.ConclusionsThe COM-B model was a helpful framework for increasing understanding of hand hygiene behavior; it identified capability, opportunity, and motivation as predictors of both handwashing and hand sanitizer use.
