Parent-child mental health in Ukraine in relation to war trauma and drone attacks.

Background: We aimed to address the knowledge gap regarding mental health in Ukrainian children and parents one year after Russia's 2022 full-scale invasion including associations with exposure to drone attacks.

Methods: A cross-sectional, quota-sampled survey was conducted among parents of children aged 3-17 in Ukraine one year after the invasion (n = 858). Participants completed self-reported screening measures of the Pediatric Symptom Checklist-17, Child and Adolescent Trauma Screen-Caregiver, Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, the International Trauma Questionnaire, and the University of California, Los Angeles (UCLA) 3-Item Loneliness Scale.

Knowledge-based risk assessment under uncertainty for species invasion.

Management of invasive species depends on developing prevention and control strategies through comprehensive risk assessment frameworks that need a thorough analysis of exposure to invasive species. However, accurate exposure analysis of invasive species can be a daunting task because of the inherent uncertainty in invasion processes. Risk assessment of invasive species under uncertainty requires potential integration of expert judgment with empirical information, which often can be incomplete, imprecise, and fragmentary.
