[Inpatient Psychodynamic Therapy for Children and Adolescents with Complex ADHD: Results of a Naturalistic Clinical Trial].

The Attention deficit/hyperactivity disorder (ADHD) is a common mental disorder in childhood and adolescence. However, it is a very heterogeneous disorder with subgroups of patients with mild symptoms and others with severe and complex impairments. Patients suffering from complex ADHD are usually characterized by multiple developmental disorders and impaired personality development. Due to the multimodal origin of the disorder, multimodal treatment approaches aimed at reducing the various deficits are usually indicated. The current study evaluated a multimodal inpatient psychodynamic treatment (PDT) for children and adolescents suffering from ADHD. 47 patients (age 9-17 years) were included in the study. Next to complex impairments (comorbid mental disorders, deficits regarding psychic structure, learning disorders and sensorimotor integration disorders), a high number of adverse childhood experiences (M = 11.71) was particularly remarkable in the sample. The PDT led to significant improvements regarding ADHD symptoms and general level of functioning. However, first symptom improvements were already evident at the end of the waiting period. For ten patients who participated in the follow-up assessment effects remained stable six months after treatment. Due to the high drop-out rate, however, the study results have to be regarded as preliminary.
