Utilization of Mental Health Care Services Among Children and Adolescents with ADHD in Germany: Treatment Satisfaction and Factors Influencing Access.

Background: ADHD is one of the most common mental disorders in children and adolescents. While international research on health service utilization, barriers to care, and treatment satisfaction is growing, evidence from Germany remains limited. This study aimed to examine the utilization of mental health care services in a sample of German children and adolescents with an administrative ADHD diagnosis registered with their health insurance company. Treatment satisfaction, belief in treatment efficacy and factors influencing mental health care utilization were examined.

Methods: As part of the consortium project INTEGRATE-ADHD, data from 4,948 children and adolescents were analyzed. Parents of 7- to 17-year-olds participated in an online survey answering questions about their child's ADHD health care utilization, treatment satisfaction and efficacy, and factors influencing utilization using established instruments. Sociodemographic factors, geographic characteristics, ADHD symptom severity, and parental psychopathology were also assessed. Descriptive analyses and multivariate logistic regressions were conducted.

Results: Approximately 40% of the children and adolescents with an administrative ADHD diagnosis were currently receiving ADHD treatment. The majority of parents (76%) were satisfied with the treatment, and 85% considered the treatment effective. Children with more severe ADHD symptoms had a threefold higher likelihood of receiving treatment, while youths with a migration background were less likely to receive mental health care. The most common reasons for not utilizing mental health care included the treatment having already ended, a lack of available treatment options, long waiting times, a lack of motivation among children, or the inability to continue treatment due to the COVID-19 pandemic.

Conclusions: To overcome the identified barriers in ADHD treatment, we recommend improving access to evidence-based ADHD treatment and expanding its implementation to prevent undertreatment and the associated individual suffering and societal costs.
