目标：在许多医疗研究中，6项Spielberger州焦虑量表已被用作原始版本的替代。这项研究的目的是使用一般医学实践患者中的Rasch分析评估缩短6个项目Spielberger州焦虑量表的测量特性（n = 297）。基于三种一般医学实践的基础。在任命之前，要求参与者完成6个项目的Spielberger州焦虑量表。研究结果：研究结果表明该量表是单位的，每个项目都测量了不同水平的患者焦虑。评分量表运行良好，项目和人的可靠性很好。此外，对残差的主要组件分析证实了量表衡量了一个单一的概念。生成了一个评分键，以使原始分数转换为连续测量。结论：6个项目Spielberger州焦虑量表比原始版本短，具有良好的心理测量特性。这表明该量表是用于主要医疗保健实践和研究的完整版本的有效替代方法。
Objectives:The 6-item Spielberger State Anxiety Scale has been used as a replacement of the original version in many health-care studies. The purpose of this study was to evaluate the measurement properties of the shortened 6-item Spielberger State Anxiety Scale using Rasch analysis in general medical practice patients (N = 297).Methods:Participants (aged 16 years or above) were recruited on a consecutive basis from three general medical practices. Prior to their appointment, participants were asked to complete a 6-item Spielberger State Anxiety Scale.Results:The results of the study showed that the scale is unidimentional, and each item measures a different level of patient anxiety. The rating scale operated well and item and person reliability was good. Furthermore, principal-components analysis of the residuals confirmed the scale measures a unitary concept. A scoring key was generated to allow conversion of raw scores to a continuous measurement.Conclusion:The 6-item Spielberger State Anxiety Scale is shorter than the original version and has good psychometric properties. This would suggest the scale is a valid alternative to the full version for use in primary health-care practice and research.
