CDCTreatment Outcomes & Access to Care
Evidence-based treatments like CBT and telehealth have strong outcomes for children, yet significant treatment gaps persist due to workforce shortages and geographic barriers.
~50%
Treatment gap
Only about half of children and adolescents with diagnosable mental health conditions receive needed treatment, leaving millions without care.
AACAP49.4%
CBT remission rate for anxiety
In a meta-analysis of 39 studies, 49.4% of youth with a primary anxiety disorder achieved remission after CBT, compared to 17.8% in waitlist or no-treatment conditions.
PMC / NIH40%
Telehealth share of youth mental health
Telehealth now accounts for approximately 40% of all mental health service encounters for youth, up from 28% in 2022, with outcomes comparable to or exceeding in-person care for anxiety disorders.
PMC / SAMHSA Analysis, 202572%
Counties without child psychiatrists
Nearly three-quarters of U.S. counties lack a single practicing child and adolescent psychiatrist, creating severe geographic barriers to specialty care.
AACAP6 in 10
Moderate-to-severe ADHD
About 6 in 10 children with ADHD have moderate or severe symptoms. Of those ever diagnosed, 92.6% still have current ADHD (6.5 million children), and 51% have two or more co-occurring disorders.
CDC, 2022 NSCH1 in 5
High schoolers considered suicide
In 2023, 20% of U.S. high school students seriously considered attempting suicide in the past year, and 16% made a suicide plan. Suicide remains the second leading cause of death for ages 10-14.
CDC YRBS, 2023Trends & Emerging Data
Pediatric mental health conditions have been increasing in prevalence over the past decade, underscoring the urgency of early intervention and expanded access to care.
+62%
Youth suicide rate increase
The suicide rate among young people ages 10-24 increased 62% from 2007 through 2021, rising from 6.8 to 11.0 deaths per 100,000.
CDC40%
Children not receiving services
Approximately 40% of children with mental, behavioral, and developmental disorders did not receive mental health services in the prior 12 months during 2016-2021.
CDC PCD19.2%
Adolescent depression (12-19)
Based on 2021-2023 data, depression prevalence was highest in adolescents ages 12-19 (19.2%), with the rate in females (26.5%) more than double that of males (12.2%).
CDC NCHS Data Brief #527, April 2025Clinical Terms Parents Should Know
Understanding clinical terminology can help parents and caregivers navigate conversations with healthcare providers and make informed decisions about their child's care.
- Cognitive Behavioral TherapyCBT
- A structured, goal-oriented form of psychotherapy that helps children identify and change unhelpful thought patterns and behaviors. CBT is the most extensively studied psychotherapy for anxiety and depression in children, with meta-analyses showing remission rates of approximately 50% for childhood anxiety disorders.
- Dialectical Behavior TherapyDBT
- A type of cognitive behavioral therapy that emphasizes mindfulness, distress tolerance, emotion regulation, and interpersonal effectiveness. Originally developed for adults, DBT has been adapted for adolescents and is commonly used for self-harm, suicidal ideation, and emotion dysregulation.
- Applied Behavior AnalysisABA
- A therapy approach based on learning theory that systematically applies interventions to improve socially significant behaviors. ABA is the most widely researched intervention for autism spectrum disorder and focuses on reinforcing desired behaviors while reducing those that may be harmful or interfere with learning.
- Psychoeducation
- The process of providing patients and families with information about mental health conditions, treatment options, and coping strategies. Psychoeducation has been shown to improve treatment adherence and outcomes across multiple pediatric mental health conditions.
- Executive Function
- A set of cognitive processes, including working memory, flexible thinking, and self-control, that help children plan, focus attention, remember instructions, and manage multiple tasks. Executive function deficits are a hallmark of ADHD and can also occur with anxiety and mood disorders.
- Comorbidity
- The simultaneous presence of two or more disorders in one individual. In pediatric mental health, comorbidity is common. For example, approximately 51% of children with ADHD have at least two co-occurring conditions such as anxiety or behavioral disorders.
- Measurement-Based CareMBC
- A clinical practice in which standardized rating scales and questionnaires are administered at regular intervals to track symptom severity and treatment progress. MBC enables data-driven treatment adjustments and has been shown to improve therapeutic outcomes.
- Telemental Health
- The delivery of mental health services through video conferencing, phone calls, or other remote communication technologies. Telehealth now accounts for roughly 40% of youth mental health encounters, with research showing outcomes comparable to in-person care while reducing barriers related to geography and scheduling.
- Selective Serotonin Reuptake InhibitorSSRI
- A class of medication commonly prescribed for anxiety and depression in children and adolescents. SSRIs work by increasing serotonin levels in the brain. When combined with CBT, SSRIs have shown superior outcomes compared to either treatment alone for childhood anxiety.
- Individualized Education ProgramIEP
- A legally binding document developed for each public school student who qualifies for special education services under the Individuals with Disabilities Education Act (IDEA). IEPs outline specific academic goals, accommodations, and related services, including mental health supports, tailored to the child's needs.
According to the CDC, approximately 1 in 5 children aged 3-17 in the United States has a diagnosable mental, behavioral, or developmental disorder. The most common conditions are anxiety (11%), ADHD (11.4%), and behavioral disorders (8%). Depression affects about 4% of children in this age range but rises to 19.2% among adolescents aged 12-19.
Cognitive behavioral therapy (CBT) is the most extensively researched and effective psychotherapy for childhood anxiety disorders. Meta-analyses show that approximately 49.4% of children with anxiety achieve full remission after CBT treatment, compared to 17.8% in untreated control groups. Combined CBT and medication (such as SSRIs) has shown even higher response rates.
Yes. Telehealth now accounts for approximately 40% of all youth mental health service encounters, and research consistently shows outcomes comparable to in-person care. A 2025 SAMHSA analysis found telehealth was especially effective for anxiety disorders, with 68% of youth expressing positive sentiment toward telehealth services.
The American Academy of Pediatrics recommends routine developmental screening at 9, 18, and 30 months of age, with autism-specific screening at 18 and 24 months. Mental health screening, including for anxiety and depression, is recommended starting at age 8 for anxiety and age 12 for depression.
The United States has approximately 11,400 practicing child and adolescent psychiatrists, with a national average of just 15 per 100,000 children. Nearly 72% of U.S. counties lack a single practicing child psychiatrist. Contributing factors include lengthy training requirements, lower reimbursement rates, and increasing demand.
Warning signs vary by age and condition but may include: persistent sadness or irritability lasting two or more weeks, excessive worry or fear, significant changes in sleep or appetite, withdrawal from friends and activities, declining school performance, frequent physical complaints without medical cause, difficulty concentrating, and talk of self-harm or hopelessness.
