The Multidimensional Assessment of Interoceptive Awareness (MAIA) measures interoceptive body awareness, which includes aspects such as attention regulation, self-regulation, and body listening. Our purpose was to perform a preliminary validation of the MAIA in adults with stroke using Rasch Measurement Theory.
The original MAIA has 32 items that measure interoceptive sensibility, which is an aspect of body awareness. We performed a preliminary analysis with Rasch Measurement Theory to evaluate the unidimensionality and structural validity of the scale. We investigated overall fit to assess unidimensionality, person and item fit, person separation reliability, targeting, local item dependence, and principal components analysis of residuals.
Forty-one adults with chronic stroke (average 3.8 years post-stroke, 13 women, average age 57±13 years) participated in the study. Overall fit (χ 2 = 62.26, p = 0.26) and item fit were obtained after deleting 3 items and rescoring 26 items. One participant did not fit the model (2.44%). There were no floor (0.00%) or ceiling effects (0.00%). Local item dependence was found in 42 pairs. The person separation reliability was 0.91, and the person mean location was 0.06±1.12 logits.
The preliminary structural validity of the MAIA demonstrated good targeting and reliability, as well as unidimensionality, and good item and person fit in adults with chronic stroke. A study with a larger sample size is needed to validate our findings.
多维内感受性觉察评估量表（MAIA）测量内感受身体意识，包括注意力调节、自我调节和身体倾听等方面。我们的目的是使用 Rasch 测量理论初步验证 MAIA 在脑卒中成人中的有效性。
原始的 MAIA 有 32 个项目，用于测量内感受敏感性，这是身体意识的一个方面。我们使用 Rasch 测量理论进行了初步分析，以评估该量表的单维性和结构有效性。我们调查了整体拟合度以评估单维性、个体和项目拟合度、个体分离可靠性、目标、局部项目依赖性和残差主成分分析。
41 名慢性脑卒中患者（平均发病后 3.8 年，13 名女性，平均年龄 57±13 岁）参与了研究。经过删除 3 个项目并重新计分 26 个项目后，获得了整体拟合度（χ 2 = 62.26，p = 0.26）和项目拟合度。有 1 名参与者不符合模型（2.44%）。无地板（0.00%）或天花板（0.00%）效应。发现 42 对局部项目依赖性。个体分离可靠性为 0.91，个体平均位置为 0.06±1.12 对数单位。
MAIA 的初步结构有效性在慢性脑卒中成人中显示出良好的针对性和可靠性，以及单维性、良好的项目和个体拟合度。需要更大的样本量研究来验证我们的发现。
