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.
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).
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.
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.
用于常见精神障碍的基于互联网系统的不断扩散，使得需要简短的在线筛查方法。本研究旨在测试网络筛查问卷（WSQ）的心理测量特性，以检验其在意大利成年社区样本中筛查常见心理健康问题的适用性。
共有1282名受试者（女性 = 819名；平均年龄 = 42.05岁）回答了WSQ。使用敏感性、特异性和曲线下面积（AUC）以及阳性预测值（PPV）和阴性预测值（NPV），将其判别特征与意大利人群中广泛使用的其他经过验证的心理健康测量量表进行比较。
大多数WSQ子量表表现出中度到高度的特异性值。具体而言，“广场恐惧症”量表（0.947；95%置信区间[0.934, 0.960]）、“焦虑”量表（0.959；95%置信区间[0.946, 0.970]）和“惊恐障碍”量表（0.973；95%置信区间[0.964, 0.981]）显示出最高值，而“强迫”维度的值最低，为0.838，95%置信区间[0.815, 0.861]。相反，除了“抑郁”（0.716；95%置信区间[642, 798]）和“酒精滥用”（0.760；95%置信区间[560, 920]）外，WSQ在所有维度上均显示出临界敏感性值（<0.6）。
WSQ适用于区分有和没有精神疾病的人，因为它有助于确认没有疾病。然而，如果WSQ筛查结果为阳性，则需要进一步的诊断程序。
