There is little research from low- and middle-income countries examining the psychometric properties of a screening tool for social anxiety disorder. The sensitivity and specificity of the Social Anxiety Screening Questionnaire against the Mini-International Neuropsychiatric Interview as a gold standard in social phobia diagnosis were investigated using analyses of receiver operating characteristics. The %26quot;best subsets%26quot; selection procedure was conducted to determine the best three to five questions. Three questions on the screening questionnaire that best discriminate between a positive and negative diagnosis of social anxiety disorder on the MINI module were identified. Answering yes to all three of these questions gives a false-positive rate of 0.44 and a false negative rate of 0.11. For this combination, the sensitivity was 0.84, and specificity was 0.67. Additional work is needed to develop a more accurate scale that could help increase the percentage of people who receive appropriate treatment of this debilitating disorder.
