Social participation is the main outcome of physical rehabilitation programs. The aim of this study is to improve the measurement of social participation, using an instrument called the Assessment of Life Habits Scale and the Rasch model. The interval level measurement, the dimensionality and the generalizability of the item hierarchy were verified. The data from a large sample of people with spinal cord injury was analyzed and specific results were compared with expert opinions. The main properties of the instrument were satisfactory and the agreement with expert opinion was high. Principal component analysis showed multidimensionality. The item difficulty hierarchy obtained with spinal cord injury experts was different from the one obtained with traumatic brain injury experts, indicating a different difficulty level of items in relation to each population characteristics. We conclude that the instrument is appropriate for the measurement of social participation and suggest ways to improve the instrument.
社会参与是身体康复计划的主要成果。本研究的目的是使用一种名为生活习惯评估量表和拉施模型的工具来改进社会参与的测量。对项目层次结构的区间水平测量、维度和可推广性进行了验证。分析了来自大量脊髓损伤患者样本的数据，并将具体结果与专家意见进行了比较。该工具的主要特性令人满意，与专家意见的一致性很高。主成分分析显示出多维性。脊髓损伤专家获得的项目难度层次结构与创伤性脑损伤专家获得的不同，这表明与每个人口特征相关的项目难度水平不同。我们得出结论，该工具适用于测量社会参与，并提出了改进该工具的方法。
