Abstract

Background: The ever-increasing spread of Internet-based systems for common mental disorders has generated the need for brief online screening methods. This study aims to test the psychometric properties of the Web Screening Questionnaire (WSQ) to examine its suitability for screening for common mental health problems among a community sample of Italian adults. Methods: A total of 1282 subjects (F = 819; mean age = 42.05) answered the WSQ. Its discriminant characteristics were examined with other validated selected scales for measuring mental health widely used in the Italian population using sensitivity, specificity, and area under the curve (AUC), as well as positive (PPV) and negative predictive values (NPV). Results: Most of the WSQ subscales exhibited moderate to high specificity values. Specifically, the scales of ‘agoraphobia’ (0.947; 95%CI [0.934, 0.960]), ‘anxiety’ (0.959; 95%CI [0.946, 0.970]), and ‘panic disorder’ (0.973; 95%CI [0.964, 0.981]) showed the highest values whilst the ‘obsessive-compulsive’ dimension had the lowest value at 0.838, 95%CI [0.815, 0.861]. With exceptions observed for ‘depression’ (0.716; 95%CI [642, 798]) and ‘alcohol abuse’ (0.760; 95%CI [560, 920]), instead, the WSQ demonstrated critical sensitivity values (<0.6) in all dimensions. Conclusions: The WSQ was appropriate for discriminating between people with and without a psychiatric condition, as it helps to confirm the absence of disorders. However, further diagnostic procedures are required, in case of a positive WSQ screening result.
