PTSD, depression, and anxiety after the October 7, 2023 attack in Israel: a nationwide prospective study

The magnitude of the Oct 7, 2023 attack in southern Israel was without precedent. More than 1300 civilians were murdered, and 240 civilians were kidnapped and taken hostage. In this national cohort study, for which baseline outcome data were established before the attacks, a prospective assessment of posttraumatic stress disorder (PTSD), depression, and generalized anxiety disorder (GAD) was conducted one month after the attack.

A representative sample of 710 Israeli adults (362 female, 51.1%), Jews (557, 79.9%) and Arabs (153, 20.1%), aged 18-85 years (mean = 41.01, SD = 13.72) completed the study at two timepoints: T1, on Aug 20-30, 2023 (6-7 weeks before the attack) and T2, on Nov 9-19, 2023 (5-6 weeks after the attack). 30 (4.2%) of the 710 participants had direct exposure to the attack, and 131 (18.5%) had loved ones who were murdered, kidnapped, or injured during the attack.
