Mediating Role of Environmental Awareness for the Nexus between Perceived Risks of COVID-19 Pandemic and Use of Sustainable Transportation: Evidence from Urban Passengers in Ethiopia, 2022

Table 1

Operationalization of variables.

Variables	Variable type	Measurement level
Actually used mode for mobility (public vs. private transport)	Variables of interest	Nominal and binary
Use intentions for mobility (public vs. private transport)	Variables of interest
The COVID-19 pandemic is a risk (mode and speed of transmission, infection, death, and recovery rates) to me	Observed variables: for perceived risks of COVID-19 pandemic, as independent variable	Ordinal/7-point Likert scale
The COVID-19 pandemic is a risk to others
Environmental degradation caused COVID-19 pandemic	Observed variables: for environmental awareness and values, as mediator variable	Ordinal/7-point Likert scale
Climate change is anthropogenic
Climate change/global warming is a risk to me
Climate change/global warming is a risk to others
My transport mode usage helped to reduce CO2 emissions	Observed variables: for sustainable transport use behavior, as dependent variable	Ordinal/7-point Likert scale
My transport mode usage improved air quality
My transport mode usage helped to decrease noise
The environmental sustainability of my transport mode usage has increased significantly
The range/variety of my transport mode usage has increased significantly
