The vast majority of psychiatric morbidity which manifests during adult life has its onset before the age of 25 years, either evolving from childhood emotional and behavioral disorder, or appearing from early adolescence through the mid-twenties. There is growing recognition that the need for care in psychiatry substantially precedes the point that a diagnosis can be assigned according to classical concepts, with negative effects on the treatability of disorders when we wait for perfect diagnostic clarity.
In 2015, the iBerry Study was started to learn more about the etiology and course of psychopathology. This longitudinal cohort study follows 1000 adolescents from the Rotterdam Rijnmond region, the Netherlands. The study is to expect to run for ten years, inviting participants for a follow-up visit every two or three years.
Participating adolescents are invited with one of their parents for a baseline visit consisting of interviews, questionnaires, neuropsychological tests, and biological measurements to assess several determinants of psychopathology. In 2019 the inclusion will be completed.
Selected adolescents are derived from the general population by screening on behavioral and emotional problems in the first class of secondary school. Screening takes place at the ‘Centrum Jeugd & Gezin Rijnmond’ in close collaboration with the Erasmus MC, department of Psychiatry. By assessing their self-reported emotional and behavioral problems, adolescents having more emotional and/or behavioral problems at the age of 13 years were oversampled in the cohort. Using this strategy we hope to find higher incidence of psychiatric disorders, and therefore, to enhance power to identify developmental trajectories and causal pathways.
the iBerry Study is open to many different types of research collaboration. For more information or to pursue a research collaboration, contact dr. Nina Grootendorst at firstname.lastname@example.org.

1. Monitoring service use and treatment outcome. Service use is evaluated by investigating trends in the use of different types of compulsory measures and routine outcome monitoring.
2. Reduction of the use of involuntary care. Studies are aimed at prevention of compulsory measures by means of risk assessment, risk management, and tailor maid care arrangements that contribute to continuity of care.
3. Strengthening treatment engagement in severe mentally ill patients. Impaired awareness of illness and lack of social support prevent severely mentally ill patients from influencing their care plan.
