Overview of the study hypotheses and hypothesis testing situation

Hypothesis	Independent variable A：COVID-19 status		Independent variable B: domain		Independent variable C: decision maker role		Testing situation
	pre-COVID-19	during COVID-19	economy	health	choices for others	choices for themselves
H1	The main effect of COVID-19 status is significant. Compared with the pre-COVID-19 condition, the preference for immediate options is enhanced under the during-COVID-19 condition (main effect of A).						Hypotheses 1 is supported.
H2	The main effect of the decision maker role is significant. When making intertemporal choices for others than themselves, decision makers prefer delayed options (main effect of C).						Hypotheses 2 is supported.
H3	The interaction between COVID-19 status and decision makers role is significant. In the during-COVID-19, the difference of self-other intertemporal choice is greater than that in the pre-COVID-19 condition (interaction between A and C).						Hypotheses 3 is supported.
H4	The main effect of the domain is significant. Compared to the intertemporal choice in the economy domain, individuals prefer delayed options in the health domain (main effect of B).						Hypotheses 4 is supported.
H5	The interaction of COVID-19 status and domain is significant (interaction between A and B).						Hypotheses 5 is supported.
H6	The interaction of decision maker role and domain is significant (interaction between B and C).						Hypotheses 6 is not supported.
H7	The interaction among COVID-19 status, decision maker role, and domain is significant (interaction among A, B and C).						Hypotheses 7 is not supported.
H8	Psychological safety plays a moderating role on the relationship between COVID-19 and intertemporal choice (moderate the relationship between A and intertemporal choice).						Hypotheses 8 is supported.
