Therapy satisfaction is widely considered an important aspect of clinical care. Still, there are currently no freely available questionnaires for its measurement. We developed the Lübeck Medication Satisfaction Questionnaire (LMSQ) for that purpose. Here, we present its content and psychometric properties.
The LMSQ was validated on 86 patients in a single center study. The Kaiser-Meyer-Olkin test, confirmatory factor analysis, covariance analysis, and a test of exact fit were performed. Reliability was tested using Cronbach's α and McDonald's ω. The relationship to other patient-reported outcomes was tested using Pearson's correlation.
Confirmatory factors analysis yielded moderate factor loadings with < 0.001 in all subscales. Reliability was adequate (α = 0.857 and ω = 0.872). Model fitness was excellent in all tests. The LMSQ was positively correlated with medication adherence (r = 0.603, < 0.001) and most dimensions of health literacy.
The LMSQ possesses adequate psychometric properties for its purpose. We recommend further validation in a more diverse patient collective.
治疗满意度被广泛认为是临床护理的一个重要方面。然而，目前尚无免费可得的用于测量治疗满意度的问卷。我们为此开发了吕贝克药物满意度问卷（LMSQ）。在此，我们介绍其内容和心理测量特性。
在一项单中心研究中，对86名患者进行了LMSQ验证。进行了凯泽 - 迈耶 - 奥尔金检验、验证性因子分析、协方差分析和精确拟合检验。使用克朗巴赫α系数和麦克唐纳ω系数检验信度。使用皮尔逊相关性检验其与其他患者报告结局的关系。
验证性因子分析在所有子量表中产生了中等因子载荷，P < 0.001。信度良好（α = 0.857，ω = 0.872）。在所有测试中模型拟合度都非常好。LMSQ与药物依从性呈正相关（r = 0.603，P < 0.001），与健康素养的大多数维度也呈正相关。
LMSQ具有适用于其目的的心理测量特性。我们建议在更多样化的患者群体中进一步验证。
