Within the occupational health setting, somatoform disorders are a frequent cause of sick leave. Few validated screening questionnaires for these disorders are available. The aim of this study is to validate the PHQ-15 in this setting.
In a cross-sectional study of 236 sicklisted employees, we studied the performance of the PHQ-15 in comparison with the Mini International Neuropsychiatric Interview (MINI) as golden reference standard. We approached employees who were sick listed for a period longer than 6 weeks and shorter than 2 years for participation. This study was conducted on one location of a large occupation health service in the Netherlands, serving companies with more than 500 employees. All employees who returned the PHQ-15 were invited for the MINI interview. Specificity and sensitivity were calculated for optimal cut point and a receiver operating characteristic (ROC) was constructed.
A total of 107 participants consented to participate in the MINI interview. A non-response analysis showed no significant differences between groups. According to the MINI, the prevalence of somatoform disorders was 21.5%, and the most frequent found disorder was a pain disorder. The PHQ-15 had an optimal cut point of 9 (patients scoring 9 or higher (≥9) were most likely to suffer from a somatoform disorder), with specificity and sensitivity equal to 61.9 and 56.5%, respectively. ROCs showed an area under the curve (AUC) of 0.63.
The PHQ-15 shows moderate sensitivity but limited efficiency with a cut point of 9 and can be a useful questionnaire in the occupational health setting.
在职业健康环境中，躯体形式障碍是导致病假的常见原因。目前仅有少数经过验证的躯体形式障碍筛查问卷。本研究旨在验证 PHQ-15 在该环境中的适用性。
在一项对 236 名请病假员工的横断面研究中，我们研究了 PHQ-15 与迷你国际神经精神访谈（MINI）作为金标准相比的表现。我们接触的是请病假时间超过 6 周且不超过 2 年的员工。这项研究在荷兰一家大型职业健康服务机构的一个地点进行，为拥有 500 多名员工的公司提供服务。所有返回 PHQ-15 的员工都被邀请参加 MINI 访谈。我们计算了最佳截断点的特异性和敏感性，并构建了接收者操作特征（ROC）曲线。
共有 107 名参与者同意参加 MINI 访谈。非应答分析显示两组之间无显著差异。根据 MINI，躯体形式障碍的患病率为 21.5%，最常见的发现障碍是疼痛障碍。PHQ-15 的最佳截断点为 9（得分 9 或更高（≥9）的患者最有可能患有躯体形式障碍），特异性和敏感性分别为 61.9%和 56.5%。ROC 显示曲线下面积（AUC）为 0.63。
PHQ-15 具有中等敏感性，但截断点为 9 时效率有限，在职业健康环境中可以作为一种有用的问卷。
