Enhancement of PTSD treatment through social support in Idobata-Nagaya community housing after Fukushima’s triple disaster

Cognitive–behavioural therapy is a first-line treatment for post-traumatic stress disorder (PTSD), but it is difficult to implement in disaster settings. We report the case of an 80-year-old Japanese woman, who was diagnosed with PTSD after the 2011 triple disaster (earthquake, tsunami and nuclear plant accident) in Fukushima. Her recovery was greatly enhanced by the social support she received while living in Idobata-Nagaya community housing, established by Soma city in Fukushima, where residents could naturally discuss their traumatic experiences. Habituation to traumatic memories and processing of cognitive aspects of the psychological trauma, which are therapeutic mechanisms of trauma-focused psychotherapies, spontaneously occurred in this setting. The details of this case support the effectiveness of Idobata Nagaya as a provider of psychological first aid, an evidence-informed approach to assist children, adolescents, adults and families in the aftermath of a disaster.
