Abstract
We plan to conduct an online experiment on improving heat related-illness prevention behaviors and knowledge for the elderly in order to verify whether a daily survey on the behaviors and/or economic incentive will have any impact on the effective prevention. Individual participants (aged 65 and over) will be randomly assigned to one of 3 intervention groups. Each subject participates in a 28 consecutive experimental session. The first group will be assigned every day to an online survey on whether he or she took heat related-illness prevention behaviors last night. The second one will be assigned the same survey and be paid monetary incentive based on the number of days in which he or she used an air-conditioner at hot night. The last one will be the control group without the survey or economic incentive.

Interventions

Intervention(s)
We will conduct an online experiment on improving heat related-illness prevention behaviors and knowledge for the elderly. Individual participants (aged 65 and over) will be randomly assigned to one of 3 intervention groups. Each subject participates in a 28 consecutive experimental session. The first group will be assigned every day to an online survey on whether he or she took heat related-illness prevention behaviors last night. The second one will be assigned the same survey and be paid monetary incentive based on the number of days in which he or she used an air-conditioner at hot night (JPY30 a night). The last one will be the control group without the survey or economic incentive.

Experimental Design Details
Randomization Method
Randomization will be done by assigning computer generated random numbers to participants.
Randomization Unit
Each participant will be randomly assigned to an intervention group.
Was the treatment clustered?
Yes

Experiment Characteristics

Sample size: planned number of clusters
A total of 900 individual subjects will participate in the experiment. The subjects will be randomly assigned to each of three treatment groups (300 subjects X 3 groups).
Sample size: planned number of observations
Each subject participates in one of three treatment groups. Hence, we collect observations of 900 individual subjects in total.
Sample size (or number of clusters) by treatment arms
Each treatment has 300 individual subjects.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
