Intellectual humility predicts COVID-19 preventive practices through greater adoption of data-driven information and feelings of responsibility

Preventive health practices have been crucial to mitigating viral spread during the COVID-19 pandemic. In two studies, we examined whether intellectual humility—openness to one's existing knowledge being inaccurate—related to greater engagement in preventive health practices (social distancing, handwashing, mask-wearing). In Study 1, we found that intellectually humble people were more likely to engage in COVID-19 preventive practices. Additionally, this link was driven by intellectually humble people's tendency to adopt information from data-driven sources (e.g., medical experts) and greater feelings of responsibility over the outcomes of COVID-19. In Study 2, we found support for these relationships over time (2 weeks). Additionally, Study 2 showed that the link between intellectual humility and preventive practices was driven by a greater tendency to adopt data-driven information when encountering it, rather than actively seeking out such information. These findings reveal the promising role of intellectual humility in making well-informed decisions during public health crises.     

A comparison of prompts and feedback for promoting handwashing in university restrooms

We compared the effects of prompts versus feedback on handwashing behavior across six restrooms at a large university. We evaluated the effects using two separate multiple baseline designs across three men's and three women's restrooms. Results indicate that feedback was more effective for increasing handwashing.     

Effects of a handwashing intervention package on handwashing in preschool children

Young children who attend out‐of‐home care (e.g., preschool) are more susceptible to infections than children who do not attend out‐of‐home care. Previous research suggests handwashing is effective in reducing risk of infection and illness. However, research suggests that individuals do not routinely wash their hands using methods that healthcare agencies, such as the Centers for Disease Control and Prevention, have determined best practice. We evaluated the effects of a multicomponent handwashing intervention package on correct handwashing across groups of preschool children. Furthermore, we measured the degree to which their hands were clean using premeasures and postmeasures. Results suggest the intervention package was effective at increasing both correct handwashing and cleanliness of participants' hands.     

The effects of perceived social norms on handwashing behaviour in students

Handwashing is widely considered the most effective method of preventing the spread of infectious illness. Exploring the determinants of handwashing is vital to the development of interventions to increase this behaviour. A survey based on Social Norms Theory assessed handwashing frequency and perceptions of peer handwashing in 255 university students. Participants reported their own handwashing frequency, and how often they thought their peers washed their hands in particular circumstances, to determine whether misperceptions around handwashing exist, and whether these influence the behaviour of individuals. Gender was found to be a significant determinant of handwashing frequency as females reported washing their hands significantly more often than males. Participants also believed they washed their hands significantly more frequently than their peers. Perceived peer handwashing frequency was significantly correlated with participants’ own behaviour. This effect was seen in overall handwashing and in food, waste and illness-related hand washing. These results suggest perceived social norms around hand washing have a clear association with individual behaviour. Future research might test the effectiveness of a social norms intervention in other settings which carry an increased risk of infection spread.     

Increasing handwashing in young children: A brief review

Personal hygiene is critical for preventing the spread of infection. One important component of personal hygiene is handwashing. This review summarizes research on behavioral strategies to address handwashing in children, offers areas for additional research, and suggests a treatment package to teach handwashing to young children.
