OBJECTIVE
The German version of the Social Phobia and Anxiety Inventory (SPAI-G) is a validated measure for the detection of social anxiety disorder (SAD). The aim of the present study was to develop optimal cut points (OC) for remission and response to treatment for the SPAI-G.
METHODS
We used Receiver Operating Characteristic methods and bootstrapping to analyse the data of 359 patients after psychotherapeutic treatment. OCs where defined as the cut points with the highest sensitivity and specificity after bootstrapping.
RESULTS
For remission, an OC of 2.79 was found, and for response, a change in score from pre- to posttreatment by 11% yielded best results.
CONCLUSIONS
The OC we identified for remissionmay be used to improve the diagnostic utility of the SPAI-G. However, the cut point for response achieved only borderline-acceptable levels of sensitivity and specificity, calling into doubt their utility in clinical and research setting.
目的
《社交恐惧症与焦虑量表》德文版（SPAI-G）是一种经验证可用于检测社交焦虑障碍（SAD）的测量工具。本研究的目的是为SPAI-G制定缓解和治疗反应的最佳切点（OC）。
方法
我们采用接受者操作特征方法和自抽样法分析了359例接受心理治疗后患者的数据。OC被定义为自抽样后具有最高敏感性和特异性的切点。
结果
对于缓解，发现OC为2.79；对于反应，治疗前后得分变化11%产生了最佳结果。
结论
我们确定的缓解OC可用于提高SPAI-G的诊断效用。然而，反应切点仅达到敏感性和特异性的临界可接受水平，这使其在临床和研究环境中的效用受到质疑。
