The distress thermometer (DT) is a useful measure of psychological distress in cancer patients. Our objective was to investigate distress impact on oncology patients in Turkey and determine the optimal cut-off score on the DT for identifying clinically significant distress. One hundred and eighty two cancer patients completed the DT, Problem List (PL), and Hospital Anxiety and Depression scale (HADS), The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30 version 3.0). The receiver operating characteristic (ROC) curve analyses of DT scores yielded an estimated area under the curve of 0.66 when compared to the HADS cut-off score, suggesting the DT is an effective scale to discriminate between classified cancer patients both with and without clinically significant distress. The DT cut-off score of 4 yielded the optimal combination of sensitivity and specificity. Scores on the DT were moderately correlated to the HADS (p<0.01) and EORTC QLQ-C30. Based on the significant correlations, we conclude that the DT has acceptable criterion validity.
痛苦温度计（DT）是衡量癌症患者心理痛苦的一种有用工具。我们的目的是调查痛苦对土耳其肿瘤患者的影响，并确定DT上用于识别具有临床意义的痛苦的最佳临界值。182名癌症患者完成了DT、问题清单（PL）、医院焦虑抑郁量表（HADS）以及欧洲癌症研究与治疗组织生活质量问卷（EORTC QLQ-C30第3.0版）。与HADS临界值相比，DT得分的受试者工作特征（ROC）曲线分析得出曲线下面积估计值为0.六6，这表明DT是区分有和没有临床意义痛苦的分类癌症患者的有效量表。DT临界值为4时产生了敏感性和特异性的最佳组合。DT得分与HADS（p<0.01）和EORTC QLQ-C30中度相关。基于这些显著相关性，我们得出结论，DT具有可接受的效标效度。
