Children and adolescents in the United States are facing a mental health crisis. According to a 2019 study by Dr. Daniel G. Whitney and Dr. Mark D. Peterson from the University of Michigan, approximately 16.5% of US children are living with at least one mental health disorder, and the state-level prevalence ranged from 7.6% in Hawaii to 27.2% in Maine. These numbers serve as a sobering reminder of the urgent need for better mental health care. In response, many states have instituted programs to address this crisis, and, as of today, California is the clear leader in this space.
In 2021, Governor Newsom of California established the Children and Youth Behavioral Health Initiative (CYBHI), a multi-year multi-billion-dollar effort to transform how behavioral health services are delivered to youth ages 0–25. CYBHI includes a wide array of programs, such as:
- BrightLife Kids & Soluna: A $680 million contract was awarded to BrightLine and Kooth to develop free digital platforms offering behavioral health coaching and educational content. Between their launch in January 2014 and July 2025, over 62,000 coaching sessions had been provided. However, with over 13 million youth eligible, this means only 0.46% have used the services.
- Cal-MAP: A pediatric mental health e-Consult program supporting primary care providers.
- Evidence-Based Practice Grants: Provides funding for proven and culturally responsive interventions.
- CalHOPE: Crisis support and resilience-building resources.
- School-Linked Fee Schedule: Establishes a standardized reimbursement model for school-based services.
- Dyadic Services: Medi-Cal coverage for joint child-caregiver therapy.
- BHCIP: Infrastructure investments to expand behavioral health facilities.
- SBHIP: Incentives for Medi-Cal plans to partner with schools.
- Positive Parenting Thriving Kids: Programs promoting healthy parenting and child development
What does the data say?
While these policies have good intentions, their real-world impact is uncertain. In 2022, Dr. David Grodberg from Yale University and his colleagues led an investigation into the effectiveness of the BrightLine app as a tool to support behavioral health. However, despite their promising findings, I suspect the state-wide rollout of these apps could have unintended consequences. Here’s what my preliminary research found:
1. No Impact on Major Depression Diagnoses
Using data from Epic Cosmos (covering over half of California’s population), I tracked new diagnoses of major depression among youth from 2021 to 2024. The numbers remained stable, suggesting that while coaching may offer support, it does not replace clinical treatment for serious mental health conditions.
2. Possible Job Losses Among School Psychologists
Using Bureau of Labor Statistics data and a Synthetic Control Method comparing California to other large states, I estimated a 14.4% decline in school psychologist employment after the policy’s rollout. This raises concerns about labor market displacement: are digital tools replacing in-person professionals?
3. Declining Mental Health Over Time
Using the Panel Study of Income Dynamics (PSID) Child Development Supplement, I analyzed Strengths and Difficulties Questionnaire (SDQ) scores for California vs. non-California children in 2024.
- In the first half of 2024, California children had better mental health scores than their peers from other states.
- In the second half, their scores deteriorated significantly, while non-California children improved.
This pattern may suggest a troubling trend, but as a social scientist, I must emphasize that these findings are not causal, as many other factors could explain the observed decline in children’s mental health. For example, 2024 was an election year, and the heightened political tension, particularly in California, may have contributed to the shifts in emotional well-being. These results must be interpreted with caution and viewed as part of a broader, more complex landscape
Where Do We Go From Here?
California’s CYBHI represents a bold and necessary investment in youth mental health, but early data suggests that digital coaching alone may not be enough to meet the complex needs of children and young adults. As the initiative continues to evolve, policymakers should take a thoughtful, evidence-based approach to ensure its success. This means integrating digital tools with in-person care, rather than allowing technology to replace human connection. It also requires monitoring the impact on the behavioral health workforce, especially in schools, where professionals play a critical role in early intervention. And most importantly, success should be measured not just by app downloads or session counts, but by long-term outcomes: are children actually getting better? California’s efforts in this space are commendable, but like any ambitious policy, CYBHI must be continuously evaluated and refined.
