Factors associated with ICD-11 posttraumatic stress disorder and complex posttraumatic stress disorder among older adults during the COVID-19 pandemic.

ICD-11 posttraumatic stress disorder (PTSD) and complex PTSD have been understudied in the older population. The study focused on the associations between traumatic exposure before the pandemic, COVID-19 worries, depression, and loneliness with current PTSD and CPTSD among older adults. A random sample of five hundred and twelve Israeli older adults ( 72.67 ± 3.81, range 68-87) was recruited using a Web-based survey company ( Participants completed questionnaires of demographic details, self-rated health, COVID-19 worries, trauma exposure, depressive symptoms, level of loneliness, PTSD, and CPTSD. Univariate logistic regression revealed that trauma exposure, COVID-19 worries, depression, and loneliness were associated with PTSD. Multinomial regression revealed that only trauma exposure was associated with PTSD among older adults with PTSD compared with those not reaching the PTSD cutoff level. In the comparison between older adults suffering from CPTSD with those not reaching the PTSD cutoff level, being married, higher levels of trauma exposure, COVID-19 worries, depression, and loneliness were associated with a higher risk of CPTSD. Results suggest that specific factors may be significant psychological correlates of CPTSD symptoms among older adults during the COVID-19 pandemic. Identifying these factors could assist practitioners in tailoring more effective interventions.
