1 Causes of Anxiety in Adults and Children: A Psychological Perspective Statement of the problem Anxiety is a significant health issue affecting both children and adults. Research by the Centers for Disease Control and Prevention reveals that 25% of children aged between 13 and 18 years have an anxiety disorder, which increases their vulnerability to depression and other mental issues if appropriate interventions are not provided (Mental health surveillance among children...," 2023).
