Perceived vulnerability to disease, knowledge about COVID-19, and changes in preventive behavior during lockdown in a...

Area of Science:

• Psychology
• Public Health
• Behavioral Science

Background:

• The COVID-19 pandemic necessitated stringent public health measures, leading to widespread psychological distress.
• Understanding individual responses to pandemics is crucial for effective public health strategies.

Purpose of the Study:

• To investigate the relationship between perceived vulnerability to disease (PVD), COVID-19 knowledge, mental health symptoms (depression, anxiety), and behavioral responses during a pandemic lockdown.
• To identify how different levels of PVD influence behavioral patterns and adaptation.

Main Methods:

• An online survey of 1358 participants in Germany during lockdown.
• Utilized the Perceived Vulnerability to Disease scale (PVD), Patient Health Questionnaire (PHQ-4), and custom questionnaires for COVID-19 knowledge and behavioral changes.
• Employed confirmatory factor analysis and structural equation modeling to analyze data.

Main Results:

• COVID-19 knowledge positively predicted adaptive and preventive behaviors.
• PVD subscales (Perceived Infectability, Germ Aversion) predicted increased preventive behaviors, with Germ Aversion also predicting decreased risk behaviors.
• Psychological distress (PHQ-4) correlated with higher perceived infectability/germ aversion and decreased adaptive behavior.
• Distinct patterns of behavior, knowledge, and mental health were observed across low, medium, and high PVD groups.

Conclusions:

• Perceived vulnerability to disease is a significant factor in adopting preventive behaviors during the COVID-19 pandemic.
• Higher PVD may enhance adaptation to pandemic conditions, suggesting a complex interplay between threat perception and behavioral response.
• Findings highlight the importance of considering psychological factors in public health interventions during pandemics.
