(PSYCHIATRIC TIMES) - Anxiety disorders are one of the most common psychiatric disorders in children and adolescents, but they often go undetected or untreated. Identification and effective treatment of childhood anxiety disorders can decrease the negative impact of these disorders on academic and social functioning in youth and their persistence into adulthood.
This article reviews assessment and focuses on evidence-based treatment interventions for childhood anxiety disorders: cognitive-behavioral therapy (CBT) and SSRIs. The following anxiety disorders are discussed: separation anxiety disorder (SAD), generalized anxiety disorder (GAD), specific phobia, panic disorder, social phobia, and selective mutism. Obsessive-compulsive disorder and posttraumatic stress disorder are not covered in this article.
The prevalence of any anxiety disorder in youths ranges from 2% to 4%, with 6- and 12-month estimates between 10% to 20%, and lifetime estimates only slightly higher.1 Anxiety disorders are common in preschool children, and they follow patterns similar to those in older children. The impact of anxiety symptoms in young children may be clinically significant even if full criteria are not met.
One anxiety disorder is often comorbid with another anxiety disorder, as well as with other psychiatric disorders—especially depression and attention-deficit/hyperactivity disorder (30%). Anxiety often precedes depression; the co-occurrence of anxiety and depression increases with age and is associated with greater impairment. Furthermore, the presence of anxiety disorders in childhood increases the risk of abusing alcohol in adolescence.
Screening and assessment
During the diagnostic evaluation, clinicians need to distinguish transient and developmentally appropriate worries and fears from anxiety disorders. In addition, the impact of stressors or traumas on the development or maintenance of anxiety symptoms needs to be assessed.
Common fears among infants include loud noises, being dropped, and later, normal separation anxiety. Toddlers typically experience fear of imaginary creatures (monsters) and darkness. From age 5 to 6 years, children experience worries about physical well-being (eg, injury, kidnapping) and later, fears of natural events (storms) develop. School-aged children worry about school performance, behavioral competence, rejection by peers, health, and illness. In adolescence, worries about social competence, social evaluation, and psychological well-being are prominent.
The American Academy of Child and Adolescent Psychiatry Practice Parameter for the Assessment and Treatment of Children and Adolescents With Anxiety Disorders2 recommends the following: routine screening for anxiety in childhood, gathering information from various sources about anxiety symptoms (child, parent, teacher), assessing for comorbid disorders, and evaluating severity and functional impairment. Children may be more aware of their inner distress (GAD), parents are more likely to appreciate the impact of anxiety on family life (SAD), and teachers are skilled at observing social functioning relative to same-age peers (social phobia).
Table 1 reviews the clinical presentation for each anxiety disorder and considers the anxious thoughts, physical sensations, and behavior related to children and adolescents.
Self-report measures for anxiety, such as the Multidimensional Anxiety Scale for Children (MASC)3 and Screen for Child Anxiety-Related Emotional Disorders (SCARED),4 can help clinicians screen for anxiety symptoms at baseline and monitor response to treatment. Children and parents can use visual analogues, such as a feelings thermometer, to rate severity of anxiety symptoms and impairment during the diagnostic evaluation. Younger children may prefer other visual tools for rating, such as smiley faces and upset faces.
Somatic symptoms, such as headaches, abdominal complaints, muscle tension, restlessness, and difficulty in sleeping, commonly accompany childhood anxiety disorders. Early screening for anxiety can help decrease excessive medical workups. Assessing somatic symptoms before initiating treatment can decrease later confusion with adverse effects of medication.
