Objectives: Single-item mood scales (SIMS) are used in clinical practice and research as simple and convenient measures to track mood and response to interventions but have rarely been formally evaluated in neurological samples. The current study sought to evaluate the psychometric properties of SIMS in verbal and visual formats.Participants: Sixty-one people living in community settings in metropolitan and regional Australia, with a history of traumatic brain injury.Methods: SIMS were compared with measures of related constructs (depressed mood and satisfaction with life) on two occasions between one and three weeks apart.Results: The study met COSMIN method quality criteria for evaluation of validity. The SIMS showed evidence of construct validity, having moderate magnitude correlation coefficients with measures of similar constructs, and conversely low and non-significant correlation with dissimilar constructs. There was also evidence of discriminant validity, with significant differences based on diagnostic status (participants with depression rated SIMS lower). Correlation coefficients on the SIMS between Times 1 and 2 were of moderate magnitude, with a small but statistically significant increase in mean ratings.Conclusions: the data support the SIMS as a valid measure that can be administered to track changes in mood in clinical practice and research.

单项情绪量表（SIMS）对脑外伤患者有效吗？

目标：单项情绪量表（SIMS）在临床实践和研究中用作跟踪情绪和对干预措施的反应的简便方法，但很少在神经系统样本中进行正式评估。当前的研究旨在评估口头和视觉形式的SIMS的心理测量特性。参与者：居住在澳大利亚大都市和区域社区的61人，有颅脑外伤史。方法：将SIMS与相关措施进行比较在相隔一到三周的两个时间里构造（沮丧的情绪和对生活的满意度）。结果：该研究符合COSMIN方法质量标准，以评估有效性。SIMS显示出结构效度的证据，与相似结构的度量具有适度的幅度相关系数，相反，与不同结构的相关性较低且不显着。也有判别效度的证据，根据诊断状态而有显着差异（抑郁症患者的SIMS评分较低）。在时间1和时间2之间，SIMS的相关系数处于中等水平，平均评分略有上升，但在统计上具有显着意义。研究。
