Association between perceived organizational support and COVID-19 vaccination intention: A cross-sectional study

We examined the association between perceived organizational support (POS) and COVID-19 vaccination intention as well as the influence of the implementation of workplace infection prevention measures.

We analyzed data from an Internet survey of workers aged 20-65 years conducted in December 2020, during a period of widespread COVID-19 infection in Japan.

Of the 23 846 participants in this survey, 1958 (8%) reported very high POS. In the group with very high POS, 836 (43%) workers wanted the COVID-19 vaccination; in contrast 1382 (36%) workers in the group with very low POS wanted the vaccination. POS was associated with COVID-19 vaccination intention (odds ratio [OR] = 1.11). The OR decreased after additional adjustment for the number of workplace infection control measures (OR = 1.06). In the analysis with POS as a categorical variable, very high POS was associated with COVID-19 vaccination intention (reference: very low POS) (OR = 1.34). The OR decreased after additional adjustment for the number of workplace infection control measures (OR = 1.17). High POS was associated with COVID-19 vaccination intention (OR = 1.17) but not with vaccination intention after additional adjustment for the number of workplace infection control measures (OR = 1.05).

High POS during the COVID-19 pandemic increased employees' vaccination intention. The relationship between POS and vaccination intention was strongly influenced by implementation of workplace infection prevention measures. Implementing appropriate workplace infection prevention measures in the event of an emerging infectious disease outbreak may influence the vaccination behavior of employees, which may contribute to the acquisition of herd immunity in the community.
