新型コロナウイルス感染症のヘルスリテラシーとリスクテイク行動および予防行動との関連

In our previous study Survey 1, we found infection prevention behaviors were characterized by health literacy and found to be divided into six segments: "majority/social defense”, “self-judgment/self-protection”, "threat denying”, "hoax affinity/optimism," "vigilance/self-protection”, and "hyper-vigilance/social defense”.The purpose of this study is to confirm the validity of segmentation by health literacy and to examine its relationship with risk-taking behavior and infection prevention behavior.The 6,000 respondents to Survey 1 were asked to answer again, and the 3,800 who responded were targeting in the study.In the results, we found that the fear of infectious diseases and the cognitive bias to believe that they will not be infected led to a regression to each segment, with significant differences between the segments. Significant differences in risk-taking and infection prevention behaviors were also found among the segments. In addition, there was no significant difference in the use of the “ Go to campaign “ among the segments.In risk-taking behavior, "self-judgment and self-protection" is considered to be a risk-taking behavior if the risk of infection is judged to be low based on accurate information obtained by the individual. Threat denial" has the lowest level of infection prevention behavior and is considered to take high-risk behaviors without hesitation. Over-vigilance and social defense" is considered to be a preventive behavior instead of risk-taking behavior due to over-vigilance against infection. In the “Go to campaign” , even if the respondents were highly susceptible to infection and felt threatened by infectious diseases, and even if they had no cognitive bias against infectious diseases, they would use this campaign.
