Notes on this study

Respondents were informed that there is a 1 in 50 chance of a large earthquake in York in the next 50 years, and a 1 in 10 chance of a moderate earthquake in the next 50 years. Attribute level range as follows. Status quo in the event of an earthquake: 1200 people (close to half of York's 2500 population) experience a mental health challenge (large earthquake); 250 people (1/10 of the population) experience a mental health challenge (moderate earthquake). Maximum improvement considered from implementing adequate support systems and emergency response plans: 300 people experience mental health challenges (large earthquake); 60 people experience challenges (moderate earthquake). Expected value of the attribute calculated as: p(moderate earthquake) x moderate damage  +  p(large earthquake) x large damage
