Meaning in life and health behavior habits during the COVID-19 pandemic: Mediating role of health values and moderating role of conscientiousness

An increasing number of studies have explored health behavior changes since the COVID-19 outbreak, however, the potential mechanism leading to the acquisition of COVID-19-related health behavior habits remains largely underexplored. The current study aimed to investigate how meaning in life contributed to the Chinese general public's acquisition of COVID-19-related health behavior habits, and whether health values would play a mediating role and conscientiousness would play a further moderating role in this relation. A total of 1024 Chinese participants (age range = 17-63 years; 67.29% females) were recruited by posting flyers on an open-access web forum. All participants voluntarily completed a series of online anonymous questionnaires assessing conscientiousness, meaning in life, health values and health behavior habits. Results showed that (1) the majority of the respondents reported the acquisition of COVID-19-related health behavior habits, and meaning in life positively predicted COVID-19-related health behavior habits; (2) health values mediated the link between meaning in life and health behavior habits; and (3) conscientiousness moderated the indirect effect, such that the indirect effect was stronger among individuals with low conscientiousness. These findings have important implications for revealing the reconstruction of the Chinese public's health behavior habits and its potential mechanism that meaning in life influences health behavior habits through health values during the COVID-19 pandemic, particularly for individuals with low conscientiousness.
