Psychometric evaluation of the Spasticity-related Quality of Life 6-Dimensions instrument (SQoL-6D).
A clinimetric evaluation conducted in a multicentre, prospective, longitudinal cohort study at 8 UK sites.
Adult patients (n=104) undergoing focal treatment of upper-limb spasticity.
The SQoL-6D was administered in the clinic at enrolment and at 8 weeks, then 1-4 days later at home to assess test-retest reliability.
The SQoL-6D demonstrated adequate construct validity and unidimensionality of the scale, allowing the calculation of a Total score. Cronbach's alpha (0.74) supported the internal consistency reliability, while the intraclass correlation coefficient supported test-retest reliability (0.82). Correlation coefficients with established instruments supported convergent validity, while significant differences between known-groups (of differing clinical severity) in SQoL-6D Total score confirmed its sensitivity to both cross-sectional and longitudinal differences.
The SQoL-6D is a promising new measure to assess health status for patients with upper-limb spasticity of any aetiology. Further investigation and exploration of the allocation of weights to convert the SQoL-6D to a health-related quality of life utility index, are required.
对痉挛相关生活质量 6 维度量表（SQoL-6D）进行心理计量学评估。
在 8 个英国中心进行的多中心、前瞻性、纵向队列研究中的临床计量学评估。
接受上肢痉挛局灶性治疗的成年患者（n=104）。
在入组时和 8 周时在诊所进行 SQoL-6D 评估，然后在 1-4 天后在家中进行评估，以评估测试-重测可靠性。
SQoL-6D 表现出足够的结构有效性和量表的单维性，允许计算总分。Cronbach's alpha（0.74）支持内部一致性可靠性，而组内相关系数支持测试-重测可靠性（0.82）。与既定工具的相关系数支持收敛有效性，而在 SQoL-6D 总分方面的已知组（不同临床严重程度）之间的显著差异证实了其对横断面和纵向差异的敏感性。
SQoL-6D 是一种有前途的新方法，可用于评估任何病因的上肢痉挛患者的健康状况。需要进一步调查和探索将 SQoL-6D 转换为健康相关生活质量效用指数的权重分配。
