We aimed to find the depression rating scale with the greatest accuracy when applied by psychiatrists in Iraqi Kurdistan. We recruited 200 patients with primary depression and 200 controls living in the Kurdistan region of Iraq. The Mini International Neuropsychiatry Inventory (MINI) was used as a gold standard for DSM-IV depression. We also used: the two-item and the nine-item versions of the Patient Health Questionnaire (PHQ2, PHQ9), the Hospital Anxiety and Depression Scale (HADS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Centre for Epidemiological Studies Depression (CES-D) scale. Interviews were performed by psychiatrists who also rated their clinical judgement using the Clinical Global Impression (CGI) scale and other mental health practitioners. All scales and tools performed with high accuracy and reliability. The least accurate tool was the PHQ2; however, with only two items it was efficient. Sensitivity and specificity for all tools were above 90%. Clinicians using the CGI were accurate in their clinical judgement. The CDSS appeared to be the most accurate scale for DSM-IV major depression and the PHQ2 the most efficient. However, only the CDSS appeared to offer an advantage over psychiatrists' judgement.
