#PerceivedRisk

We use verbal phrases to communicate probability. "Certain" is higher than "Will never happen", but how much higher? Also, phrases like "Highly probably" refer to a narrower range than "Presumably". A number of studies have categorized how such phrases are used in the English language. (1/3)

We found support for the associations most frequently cited in the literature: #conscientiousness <-> #compliance, and #neuroticism <-> #perceivedRisk. Other associations that are only occasionally seen in the literature were less strongly indicated, and there were some novel discoveries.

We often assume that perceived risk determines compliance with protective measures. But both factors may vary over time, and what happens at one point may influence what happens at a later point. In a registered report that reached stage 2 approval this week (osf.io/jehm7), our team led by @sebastianbjorkheim.bsky.social examined this dynamic and bi-directional relationship over four time-points during the first year of the COVID-19 pandemic in Norway.

A robust multiverse analysis did not show consistent relationships between risk and compliance at given measurement points, nor that risk at one time predicted future compliance, or vice versa.

What characterised people who became infected in the few first weeks of the COVID-19 pandemic? Had they underestimated the risk, been in more risky situations, or not followed public health advice? We compared perceived risk, behaviour and compliance of early covid patients with that of other types of patients and the general public.

We found that COVID-19 patients had travelled more, had been more exposed to other infected people and thought of themselves as generally less compliant to infection prevention. It is less clear whether they had thought differently about infection risk, had been more exposed in other types of situations, or had been less compliant to specific examples of infection prevention measures. Self-reported memory artefacts should be taken into account.

Title: Perceived infection risk, infection exposure, and compliance to infection control measures among the first COVID-19 patients in Norway Aims: The COVID-19 pandemic provided a unique opportunity to assess how infected patients viewed risk. We investigated whether cases infected early in the pandemic had assessed the risk to be lower, been more exposed and took fewer precautions to prevent infection. Methods: We asked first-wave Norwegian COVID-19 patients (n = 88) to recall how they had thought about risk of infection, exposure in potential infectious situations and their compliance to infection control measures early in the pandemic. Answers from this group were compared WITH emergency room patients with non-pulmonary complaints (n = 75) and with a nationally representative sample (n = 4083). Results: Both patient groups saw the risk as lower than did the representative sample. Contact with infected people was more frequent for the COVID-19 patients than for the other patients. More of the COVID-19 patients had travelled abroad immediately before the outbreak. COVID-19 patients complied less with the infection control measures than did the representative sample. The COVID-19 patients agreed less than the other patients with a statement that they had ‘complied in general’. Conclusions: Risk-behaviour was overrepresented among the first COVID-19 patients. Potential memory artefacts should be considered when interpreting the results.

I presented a poster at a conference today, but I don't think a single person saw it! 😭 Please take a look to justify the resources I put into it.

We compared how people lining up for COVID-19 testing in 2020 compared to the average population. We found that test-takers saw the risk as lower, were more exposed to infection and took fewer precautions.

Those getting tested for COVID-19 had seen the risk as low, been more exposed and taken fewer precautions Effective public health strategies in multi-crises situations often require members of the public to make informed choices that align with expert evaluations of the situation. In a pandemic, it is critical that individuals seek testing when they have legitimate concerns about being at risk. It is an empirical question whether those seeking testing are motivated by concerns that align with one or more of the legitimate reasons for testing. People may be motivated to seek testing due to believing they have been at risk for infection, they have been exposed to infection, or they have not taken sufficient precautions. We asked people at a COVID-19 test station in October 2020 (T1, n = 179) and in January-February 2021 (T2, n = 184) about their risk perception, exposure to infection sources and infection control measure compliance. Their responses were compared to those from a representative sample (T1 n = 2,523 and T2 n = 2,194) taken at approximately the same time. We found that people at test stations had seen the risk as lower, that they had more frequently been in situations where they could have been exposed to infection, and they had complied less with infection control measures. This indicates that those seeking testing had good reasons to do so. This largely supports the assumption that a well-informed public can make reasonable choices about voluntary testing.
