Anxiety disorders are among the most common psychiatric conditions in children and adolescents. Data from the National Comorbidity Survey-Adolescent Supplement, summarized by the National Institute of Mental Health, place the lifetime prevalence of any anxiety disorder in teens at approximately 32 percent. Presentation varies by age: separation anxiety in younger children, social anxiety emerging around age 13, generalized worry across ages. School refusal, somatic complaints, sleep disruption, and behavioral changes are common signals. Treatment is highly effective: cognitive behavioral therapy (often with parental involvement) and, when indicated, SSRIs that are FDA-approved for several pediatric anxiety conditions.
Pediatric anxiety is among the most common reasons for psychiatric referral and one of the most treatable. The challenge is that anxiety in children often looks like something else: stomachaches, refusal to go to school, clinginess, irritability. Parents and pediatricians sometimes spend months addressing the surface presentation before the underlying anxiety becomes clear.
What pediatric anxiety actually looks like
Anxiety in children rarely presents as the child saying "I'm anxious." It presents as behavioral and physical signals that have to be read.
In younger children (ages 3 to 8): Separation anxiety is the most common form (see separation anxiety disorder in kids and adults for the full picture). Persistent worry about being apart from parents, difficulty sleeping alone, stomachaches before school, clinginess, and excessive worry about parents' safety. Some level of separation anxiety is developmentally normal; the diagnostic threshold is that it's more intense or longer-lasting than expected for age and that it interferes with daily life.
In school-age children (ages 8 to 12): Generalized worry becomes more prominent. Worry about school performance, friendships, world events, family stability. Somatic complaints (headaches, stomachaches) often dominate the picture, with the child themselves not labeling the experience as anxiety. Sleep problems are common.
In adolescents (ages 13 to 18): Social anxiety often emerges, as does panic disorder. Generalized anxiety continues. Obsessive-compulsive symptoms may appear or worsen. The presentation begins to look more like adult anxiety, though irritability is more prominent in teens than in adults.
Across ages, common signals that anxiety has become clinically significant: school refusal, persistent somatic complaints with no clear medical cause, sleep disruption beyond what the situation explains, sudden behavioral changes, withdrawal from activities the child previously enjoyed, and excessive reassurance-seeking from parents.
The diagnostic conditions
The DSM-5-TR recognizes several anxiety conditions in children, several of which overlap with adult diagnoses:
- Separation anxiety disorder (no longer restricted to children in DSM-5)
- Selective mutism (a child who speaks normally at home but doesn't speak in specific social settings)
- Specific phobias
- Social anxiety disorder
- Panic disorder
- Generalized anxiety disorder
- Agoraphobia
- Obsessive-compulsive disorder (now in a separate DSM chapter, but clinically related)
- Post-traumatic stress disorder (also in its own chapter, with developmentally appropriate criteria for children under 6)
The specific diagnosis matters for treatment selection.
When to seek evaluation
A pediatrician or family physician is the appropriate starting point. Red flags that warrant evaluation rather than continued watchful waiting:
- Anxiety that has lasted more than two to three months and is interfering with school, friendships, or family life
- School refusal lasting more than a few days
- Significant changes in sleep, appetite, or behavior
- Recurring somatic complaints (headaches, stomachaches) that have been medically evaluated with no clear cause
- Panic attacks
- Persistent intrusive thoughts or compulsive behaviors
- Thoughts of self-harm or suicide, these warrant immediate evaluation, regardless of severity
For severe symptoms or safety concerns, the appropriate next step is a child or adolescent psychiatrist. Pediatric mental health is a subspecialty, and clinicians trained specifically in working with children and adolescents are meaningfully different from general adult psychiatrists.
What works for treatment
Cognitive behavioral therapy. CBT adapted for children and adolescents is the most-studied psychological treatment for pediatric anxiety. Strong evidence supports it for generalized anxiety, social anxiety, separation anxiety, specific phobias, and OCD. The protocols typically involve the child plus some involvement of parents, with the parental role varying by age. The Coping Cat program is one of the most-validated CBT protocols for children.
SSRIs. Several SSRIs have FDA approval for pediatric conditions: sertraline for OCD in children 6 and older, fluoxetine for OCD in children 7 and older, fluvoxamine for OCD in children 8 and older, and fluoxetine for depression in adolescents. Off-label use for generalized anxiety, social anxiety, and panic disorder is common and supported by clinical trial data, with sertraline and fluoxetine being the most commonly used.
The FDA boxed warning on increased suicidal ideation in patients under 25 applies here. The warning has been controversial in pediatric psychiatry, untreated depression and anxiety also carry suicidal risk, and the balance of risks in serious cases generally favors treatment. The clinical practice is to monitor closely in the first weeks, particularly for new or worsening suicidal thoughts, irritability, or behavioral activation.
Combined treatment. The Child/Adolescent Anxiety Multimodal Study (CAMS), one of the largest pediatric anxiety trials, found that the combination of CBT plus sertraline produced response in about 81 percent of children, higher than either treatment alone. The full results were published by Walkup et al. in the New England Journal of Medicine in 2008. For moderate-to-severe pediatric anxiety, combined treatment is often the right approach.
The parent's role
This is one of the parts of pediatric mental health that differs most from adult care. The parent is part of the treatment.
Specific parent behaviors that tend to maintain pediatric anxiety include excessive accommodation (rearranging family life to avoid the child's fear), reassurance-giving that has become chronic, taking over tasks the child could do anxiously but successfully, and modeling anxious responses to ordinary stressors.
Specific parent behaviors that tend to help include validating the feeling without fixing it ("I can see this is really hard for you"), maintaining expectations the child can meet with effort, modeling regulation rather than escalation, and working with the child's therapist on a consistent approach across home and clinic.
The SPACE program (Supportive Parenting for Anxious Childhood Emotions), developed at Yale, is a structured intervention that works exclusively with parents and has good evidence for reducing childhood anxiety even without the child participating directly in therapy.
What about school
Schools are often a significant part of pediatric anxiety, both as the trigger context and as a partner in treatment. Section 504 plans and Individualized Education Programs (IEPs) can provide accommodations for students with anxiety disorders that interfere with academic function. Common accommodations include extended testing time, breaks during the school day, reduced presentation requirements for social anxiety, and gradual re-entry plans for school refusal.
Working with the school counselor, the child's clinician, and the parent together is often more effective than any single piece in isolation.
