目的：评估修订版视觉模拟情绪量表（VAMS-R）在健康老年人和失语性中风患者中的内部一致性、有效性和因素结构。设计：横断面研究。参与者：50 名健康老年人和 71 名失语性中风患者。地点：社区和医院。措施：要求健康参与者填写医院焦虑和抑郁量表（HADS）和 VAMS-R。失语性中风患者完成了VAMS-R和视觉模拟自尊量表（VASES），中风失语性抑郁问卷21（SADQH-21）由护士或护理人员完成。结果：量表的内部一致性较高（健康成人α0.74，失语性中风患者α0.80）。 VAMS-R 与健康参与者的 HADS 显着相关（HADS 焦虑 r(s) = 0.59，P < 0.001，HADS 抑郁 r(s) = 0.49，P = 0.001）以及 VASES（r(s) = -0.69，P < 0.001）和 SADQH-21（r(s) = 0.43，P = 0.001）中风患者。探索性因素分析确定了量表中的三个因素：消极情绪状态、精力水平和幸福感。这三个因素占健康参与者方差的 73% 和失语性中风患者方差的 70%。结论：VAMS-R 显示出比原始 VAMS 更好的心理测量特性。颠倒快乐和精力充沛的项目可以提高量表评估情绪状态的能力。
Objective: To assess the internal consistency, validity and factor structure of a revised version of the Visual Analog Mood Scales (VAMS-R) in healthy older adults and aphasic stroke patients.Design: Cross-sectional study.Participants: Fifty healthy older people and 71 aphasic stroke patients.Setting: Community and hospital.Measures: The healthy participants were asked to complete the Hospital Anxiety and Depression Scale (HADS) and the VAMS-R. The aphasic stroke patients completed the VAMS-R and Visual Analogue Self Esteem Scale (VASES) and the Stroke Aphasic Depression Questionnaire 21 (SADQH-21) was completed by a nurse or carer.Results: The internal consistency of the scale was high (healthy adults alpha 0.74, aphasic stroke patients alpha 0.80). The VAMS-R correlated significantly with the HADS in healthy participants (HADS Anxiety r(s) = 0.59, P < 0.001, HADS Depression r(s) = 0.49, P = 0.001) and the VASES (r(s) = -0.69, P < 0.001) and SADQH-21 (r(s) = 0.43, P = 0.001) in stroke patients. Exploratory factor analysis identified three factors in the scale: negative mood states, energy levels and happiness. The three factors accounted 73% of the variance in healthy participants and 70% of the variance in aphasic stroke patients.Conclusions: The VAMS-R showed better psychometric properties than the original VAMS. Reversing the happy and energetic items improved the ability of the scale to assess mood states.
