Swiss residents' information behavior perceptions during the COVID-19 pandemic: A longitudinal qualitative study.

People's information behavior during the COVID-19 pandemic was challenged through vast amounts of information, misinformation, and disinformation. This study sets out to address the research gap of longitudinal, qualitative inquiries about how people's information behavior changed during the COVID-19 pandemic. It aims to assess how residents of German-speaking Switzerland perceived and evaluated information gathering during a global health crisis. As part of the "Solidarity in Times of a Pandemic" (SolPan) Research Commons, 83 semi-structured interviews with residents of German-speaking Switzerland were conducted in April 2020 (T1), October 2020 (T2), and October 2021 (T3). People were asked about their lived experiences during the COVID-19 pandemic. Qualitative data analysis followed a reflexive thematic analysis approach, using Wilson's model of information behavior as a theoretical framework. Participants perceived high-quality journalistic news media, the Swiss national government, scientific experts, and their direct social environment as trustworthy information sources. They were motivated to gather information through the wish of gaining agency and certainty in the context of a major, global health crisis. Intervening variables that hindered information seeking included a perceived lack of agency, habituation effects in the later stages of the pandemic, information overload, inconsistent information, and conspiracy theories. While information needs were generally high in T1, participants expressed a growing extent of information fatigue in T2. In T3, the most prominent themes were conflicting information and differing interpretations, which led to an increased perception of societal polarization, which was perceived as a direct consequence of participants' information behavior. This finding is contextualized through established models of attitude formation: The study indicates how participants formed rather stable attitudes over time and how this led to a growing polarization and societal segmentation as the pandemic progressed. Practical implications regarding how to meet such societal polarization during crises are discussed.
