BACKGROUND
The BSI-18 contains the three six-item scales somatization, depression, and anxiety as well as the Global Severity Index (GSI), including all 18 items. The BSI-18 is the latest and shortest of the multidimensional versions of the Symptom-Checklist 90-R, but its psychometric properties have not been sufficiently clarified yet.
METHODS
Based on a representative sample of N = 2516 participants (aged 14-94 years), detailed psychometric analyses were carried out.
RESULTS
The internal consistency was good: Somatization α = .82, Depression α = .87, Anxiety α = .84 and GSI α = .93. Confirmatory factor analysis supported the three scales as second-order and GSI as first-order factors. The model fit based on RMSEA is good but that model fit based on CFI and TLI are too low.
CONCLUSIONS
Therefore, it is a very short, reliable instrument for the assessment of psychological distress. The BSI-18 can be used to reliably assess psychological distress in the general population. However, further studies need to evaluate the usefulness of standardization in clinical samples.
背景
BSI - 18包含三个六项量表，即躯体化、抑郁和焦虑量表以及包含所有18个条目的总体严重程度指数（GSI）。BSI - 18是症状自评量表90 - R多维度版本中最新且最短的版本，但其心理测量特性尚未得到充分阐明。
方法
基于N = 2516名参与者（年龄14 - 94岁）的代表性样本进行了详细的心理测量分析。
结果
内部一致性良好：躯体化α = 0.82，抑郁α = 0.87，焦虑α = 0.84，总体严重程度指数α = 0.93。验证性因素分析支持这三个量表为二阶因素，总体严重程度指数为一阶因素。基于RMSEA的模型拟合良好，但基于CFI和TLI的模型拟合度较低。
结论
因此，它是一种用于评估心理困扰的非常简短且可靠的工具。BSI - 18可用于可靠地评估普通人群的心理困扰。然而，需要进一步研究评估其在临床样本中标准化的有用性。
