Background: The Composite International Diagnostic Interview (CIDI) has been clinically reappraised in several studies conducted mainly in the US and Europe. This report describes the methodology used to conduct one of the Middle East's largest clinical reappraisal studies. The study was carried out in conjunction with the World Mental Health Qatar-the first national psychiatric epidemiological study of common mental disorders in the country. This study aimed to evaluate the diagnostic consistency of core modules of the newly translated and adapted Arabic version of the CIDI 5.0 against the independent clinical diagnoses based on the Structured Clinical Interview for DSM-5 (SCID-5). Methods: Telephone follow-up interviews were administered by trained clinicians using the latest research edition of the SCID for DSM-5. Telephone administered interviews were key in the data collection, as the study took place during the COVID-19 pandemic.Results: Overall, within 12 months, 485 interviews were completed. The response rate was 52%. Quality control monitoring documented excellent adherence of clinical interviews to the rating protocol. Conclusions:The overall methods used in this study proved to be efficient and effective. For future research, instrument cultural adaptation within the cultural context is highly recommended.

Dandy–Walker malformation is a group of brain malformations that sometimes present with psychotic features, violent and impulsive behavior, or mood symptoms. Here, we present a case report of a patient with Dandy–Walker malformation who presented with intermittent explosive disorder. A young man, aged 18 years, was brought to the author’s hospital [Hamad Medical Corporation] with anger outbursts, irritable mood, and violent behavior. His magnetic resonance imaging scans showed typical alterations of Dandy–Walker malformation. He also had mild intellectual disabilities and epilepsy. After a few weeks of treatment with sodium valproate 1000 mg/day and risperidone 2 mg/day, his condition improved, and his violent behavior was significantly reduced in 3 months, 6 months, and 1 year of follow-up. There is broad consensus that Dandy–Walker malformation is associated with psychosis and other behavioral abnormalities because of a possible disruption in the prefrontal, thalamic, and cerebellar circuits. The link between Dandy–Walker malformation and intermittent explosive disorder may help us understand this type of brain malformation as a potential psychiatric comorbidity.
