Distributions of estimated conditional average treatment effects of disaster damages on depressive symptoms/posttraumatic stress symptoms (PTSS) in (a) 2013 and (b) 2016. We used the Geriatric Depression Scale (range, 0–15 points; higher scores indicate more depressive symptoms) to assess depressive symptoms and the Screening Questionnaire for Disaster Mental Health (range, 0–9 points; higher scores indicate more PTSS) to assess PTSS. The heterogeneous effects (ie, conditional average treatment effects) were estimated using the generalized random forest algorithm.
