The BSI-18, an abridged version of the Brief Symptom Inventory of Derogatis, contains the 3 six items scales Somatization, Depression, Anxiety, and the Global Score (GSI). In a sample of N=638 psychotherapeutic patients, reliability and validity were proven. Reliability of the 3 scales was good: Somatization α=0.79, Depression α=0.84, Anxiety α=0.84, and GSI α=0.91. The postulated three-factor structure was proven sufficiently using confirmatory and explorative factor analyses. The questionnaire separated different patients groups. Judgments of the therapists corresponded well with the self-rating behavior of the patients. In conclusion, the psychometric evaluation of the BSI-18 resulted in persuasive evidence for its reliability and validity. The loss of information, as a result of item reduction, is acceptable analyzing large samples; in cases of individual analyses, the SCL-90-R is advised.
BSI - 18是Derogatis简明症状量表的缩写版本，包含躯体化、抑郁、焦虑3个六项目量表以及总体评分（GSI）。在一个N = 638名心理治疗患者的样本中，该量表的信效度得到了验证。3个量表的信度良好：躯体化α = 0.79，抑郁α = 0.84，焦虑α = 0.84，总体评分α = 0.91。通过验证性和探索性因素分析充分证明了假设的三因素结构。该问卷能够区分不同的患者群体。治疗师的判断与患者的自评行为高度一致。总之，对BSI - 18的心理测量学评估为其信效度提供了有说服力的证据。在分析大样本时，因项目缩减导致的信息损失是可以接受的；在个体分析的情况下，建议使用SCL - 90 - R。
