Mental health problems.
Mental health impacts, which include common mental disorders, post-traumatic stress syndrome, and suicide, have not been well documented [13]. Again, much of the existing evidence comes from Western countries [3], where coping mechanisms and cultural contexts are likely to be different than in many lower-income countries [14]. However, several studies have reported increased symptoms, such as anxiety, depression, and sleeplessness, among flood victims [3,15]. Behaviour change in children has also been observed, with Durkin et al. reporting increased bed-wetting and aggression [16], and other studies reporting post-traumatic stress disorder and dissatisfaction with life [3]. Only two studies have studied suicide among flood victims, and the evidence of an effect is unclear [3].
