To investigate the psychometric properties of the Multidimensional Assessment of Fatigue (MAF) scale in a traumatic brain injury (TBI) sample.
Prospective survey study.
Community.
One hundred sixty-seven individuals with TBI admitted for inpatient rehabilitation, enrolled into the TBI Model Systems national database, and followed up at either the first or second year postinjury.
Not applicable.
MAIN OUTCOME MEASURE(S): Multidimensional Assessment of Fatigue.
The initial analysis, using items 1 to 14, which are based on a 10-point rating scale, found that only 1 item ("walking") misfit the overall construct of fatigue in this TBI population. However, this 10-point rating scale was found to have disordered thresholds. When ratings were collapsed into 4 response categories, all MAF items used to calculate the Global Fatigue Index formed a unidimensional scale.
CONCLUSION(S): Findings generally support the unidimensionality of the MAF when used in a TBI population but call into question the use of a 10-point rating scale for items 1 to 14. Further study is needed to investigate the use of a 4-category rating scale across all items and the fit of the "walking" item for a measure of fatigue among individuals with TBI.
研究多维疲劳评估量表（MAF）在创伤性脑损伤（TBI）样本中的心理测量特性。

多维疲劳评估量表。
最初的分析使用基于 10 分制的 1 至 14 项条目，发现只有 1 项条目（“行走”）在 TBI 人群中不符合疲劳的整体结构。然而，这种 10 分制被发现存在无序阈值。当评分被归为 4 个反应类别时，用于计算总体疲劳指数的所有 MAF 条目形成了一个单一维度的量表。
研究结果普遍支持 MAF 在 TBI 人群中的单一维度性，但对使用 1 至 14 项条目的 10 分制提出了质疑。需要进一步研究来探讨在所有条目上使用 4 级评分制以及“行走”项对于 TBI 个体疲劳测量的适用性。
