The World Health Organization is preparing a primary care version of the eleventh revision of the International Classification of Diseases (ICD-11 PHC). To collaborate with the development of this new classification, it is proposed to examine the validity and reliability of the proposed categories to diagnose the most common mental health disorder presented in primary care: anxious depression and Bodily Distress Disorder (BSS). Methods: It will be analyzed data collected through the ICD-11 PHC field trials in five countries (N= 2.279). General physicians, using screening questionnaires, referred patients they suspected to have depressive and/or anxiety or BSS symptoms to be interviewed by a research assistant using the Clinical Interview Schedule-Revised, a measure of disability (12-WHODAS 2.0) and two five-items depression and anxiety scales. With analysis of variance it will be evaluated the impact of the new anxious depression category on disability and suicidality. Using bifactor models it will be examined the structure and reliability of the scales containing the symptoms proposed for depression, anxiety and BSS in the ICD-11 PHC. Using regression analyses it will be assessed the external validity of the selected model against ICD-11 PHC diagnoses and disability levels. (AU)
