Objective: To construct a brief instrument (≤10 items) for the screening of anxiety and depressive disorders (ADD) in adults in Peru. Method: A secondary analysis of the database from the Epidemiological Study of Integral Health in Metropolitan Lima and Callao – Replication 2012 was conducted, which included numerous items on diverse psychiatric symptomatology and aspects of mental health, the Kessler-6 Distress Scale (K6), perceived need for help (PNH), and identification of ADD using the Mini International Neuropsychiatric Interview (MINI). The participants (N=4445) were randomly divided into 2 groups. With the first group (N=2181), an instrument was constructed by selecting items primarily based on the combination that generated the highest area under the receiver operating characteristic curve (AUC) for ADD detection. With the second group (N=2264), the validity of the generated instrument and the K6 was evaluated in relation to the presence of ADD and ADD with PNH considering the values of the AUC, sensitivity (se), specificity (sp), and Youden's index. Results: The resulting scale (SDADD-9), consisting of 9 items, had a significantly higher AUC than the K6 when considering as the reference standard the presence of ADD (0.8482 vs 0.8008) or ADD with PNH (0.9148 vs 0.8544). The suggested cut-off point for SDADD-9 is >=6 for women (se=75.34%, sp=79.08%) and >=5 for men (se=80%, sp=75.92%). Conclusions: The psychometric characteristics of the SDADD-9 suggest that it may be useful for the screening of ADD, particularly ADD with PNH.
