Against the background of the growing importance of symptom validity assessment both in forensic and clinical or rehabilitation contexts, a new instrument for identifying overreporting was developed. In order to study the equivalence of the German and the French versions, we divided the item pool of the Self-Report Symptom Inventory (SRSI) into two presumably equivalent half-forms. A sample of 40 adult bilingual Swiss nationals with a mean age of 39.9 years responded honestly to one of the half-forms in German and to the other in French. In a subsequent experimental malingering condition, they were asked to simulate sequelae of a whiplash injury and to respond to the SRSI again. In both conditions, they also filled out the Structured Inventory of Malingered Symptomatology (SIMS). The results showed no differences between the two language versions in both conditions. Classification accuracy was very high (100% specificity, 90% sensitivity for the standard cutoff score). Reliability estimates were 0.93 for endorsement of genuine symptoms and 0.97 for pseudosymptom endorsement. In the malingering condition, the correlation between the number of reported pseudosymptoms and the SIMS scores was 0.69. The current results add to the database available for the SRSI and support the appropriateness of the French version.

自我报告症状量表的德语和法语版本的等效性

在法医和临床或康复环境中症状有效性评估日益重要的背景下，开发了一种用于识别过度报告的新工具。为了研究德语和法语版本的等效性，我们将自我报告症状清单 (SRSI) 的项目池划分为两个可能等效的半形式。一个由 40 名平均年龄为 39.9 岁的双语瑞士成年人组成的样本对其中一个用德语和另一个用法语的半形式做出了诚实的回应。在随后的实验伪装条件下，他们被要求模拟鞭打损伤的后遗症并再次对 SRSI 做出反应。在这两种情况下，他们还填写了伪装症状的结构化清单 (SIMS)。结果表明，两种语言版本在两种情况下都没有差异。分类准确度非常高（100% 的特异性，90% 的标准临界值敏感性）。真实症状认可的可靠性估计值为 0.93，伪症状认可的可靠性估计值为 0.97。在伪装条件下，报告的假症状数量与 SIMS 分数之间的相关性为 0.69。当前结果添加到 SRSI 可用的数据库中，并支持法语版本的适当性。报告的假症状数量与 SIMS 分数之间的相关性为 0.69。当前结果添加到 SRSI 可用的数据库中，并支持法语版本的适当性。报告的假症状数量与 SIMS 分数之间的相关性为 0.69。当前结果添加到 SRSI 可用的数据库中，并支持法语版本的适当性。
