Values are presented as Pearson's r (P value).

Data are represented as below: children and adolescents, 6–18 years; adult, 19–64 years; elderly = ≥ 65 years.

PTSD-PC-5 = Primary Care Posttraumatic Stress Disorder Screen for DSM-5, CDI = Children's Depression Inventory, PSWQ-C = Penn State Worry Questionnaire for Children, PHQ-9 = Patient Health Questionnaire-9, GAD-7 = Generalized Anxiety Disorder Scale-7.
