To adapt and evaluate the unweighted version of the London Handicap Scale (LHS) for use in Sweden.
MATERIALS & METHODS: Respondent burden, linguistic validity and patient perceived relevance was assessed in 16 neurologically ill patients. Internal consistency reliability and construct validity were evaluated among 89 stroke survivors six months after discharge.
Patients perceived the LHS as relevant and easy to understand and complete. Mean time to complete the questionnaire was 10 min. Cronbach's alpha reliability was 0.85. The LHS differentiated between patients living at home and in special accommodations. As expected, scores correlated strongly and weakly with indices of related and more remote constructs, respectively. There were no floor-, but large ceiling effects.
The observations reported here are in accordance with previous studies using the original British LHS and provide initial support for the reliability and validity of the instrument for use in Sweden. However, ceiling effects may limit its usefulness as an outcome measure.
对伦敦残障量表（LHS）的非加权版本进行改编并评估其在瑞典的适用性。
对16名神经疾病患者评估了应答负担、语言效度和患者感知相关性。在89名卒中幸存者出院6个月后评估了内部一致性信度和结构效度。
患者认为LHS相关且易于理解和填写。完成问卷的平均时间为10分钟。克朗巴哈α信度为0.85。LHS能够区分居家患者和住在特殊护理机构的患者。正如预期的那样，分数分别与相关和较远结构指标呈强相关和弱相关。没有地板效应，但有较大的天花板效应。
此处报告的观察结果与之前使用原始英国LHS的研究一致，并为该量表在瑞典使用的信度和效度提供了初步支持。然而，天花板效应可能会限制其作为结局指标的效用。
