The Revised Body Awareness Rating Questionnaire (BARQ-R) is a self-report measure of body awareness. First aim: evaluate the structural validity of BARQ-R with Rasch analysis in community-dwelling Americans with and without musculoskeletal pain. Subaim: validate a Rasch analysis of BARQ-R done in Norwegian adults with musculoskeletal pain, through a secondary analysis in our sample of Americans with musculoskeletal pain.
BARQ-R has 12 items with scores ranging from 0 (completely disagree) to 3 (completely agree), with higher total scores reflecting lower degrees of body awareness. Through Rasch analysis, we evaluated unidimensionality, item hierarchy, and structural validity with item and person fit, targeting, person separation reliability (PSR), local item dependence (LID), differential item functioning (DIF), and principal components analysis of residuals (PCAR).
We recruited 623 adults with and without musculoskeletal pain (average age = 50.27 ± 17.25 years). After rescoring 1 item and deleting 3 items, the 9-item Rasch-based BARQ-R had no misfitting items, the hierarchical ordering of the items followed clinical expectations, 3 (0.48%) misfitting persons, person mean location: -0.62 ± 1.03 logits (max -0.53, min 0.72 logits), minimal floor effect (1.93%) and ceiling effect (0.48%), no DIF, and PSR = 0.72. LID was found in 5 item pairs. The PCAR's eigenvalue was 2.18. The secondary Rasch analysis in 152 adults with musculoskeletal pain (average age = 52.26 ± 16.13 years), demonstrated that, after rescoring 2 items, BARQ-R had no misfitting items and only 2 (1.32%) misfitting persons, good targeting (person mean location: -0.36 ± 0.88 logits), minimal floor effect (0.01%), no ceiling effect (0.00%), and PSR = 0.75. LID was found in 6 item pairs. The PCAR's eigenvalue was 2.47.
BARQ-R had good item and person fit. PSR with items covering a limited logit range suggests that differing levels of body awareness are measured with only modest precision. Adding and revising items to cover a wider range of body awareness and to better address concepts of internal body awareness and body movements would improve BARQ-R's utility. Further analyses are needed before BARQ-R's use for research or in the clinic. In addition, future BARQ-R Rasch validation is needed in other populations with body awareness deficits, such as stroke or spinal cord injury.
修订后的身体意识评定问卷（BARQ-R）是一种自我报告的身体意识测量工具。目的一：通过对有和没有肌肉骨骼疼痛的社区居民进行 Rasch 分析，评估 BARQ-R 的结构有效性。目的二：通过对我们的肌肉骨骼疼痛患者样本进行二次分析，验证在挪威有肌肉骨骼疼痛成年人中进行的 BARQ-R 的 Rasch 分析的有效性。
BARQ-R 有 12 个项目，分数范围为 0（完全不同意）到 3（完全同意），总分越高表示身体意识越低。通过 Rasch 分析，我们使用项目和个体拟合、目标、个体分离可靠性（PSR）、局部项目依赖（LID）、差异项目功能（DIF）和残差主成分分析（PCAR）来评估单维性、项目层次结构和结构有效性。
我们招募了 623 名有和没有肌肉骨骼疼痛的成年人（平均年龄 50.27±17.25 岁）。在重新评分 1 项并删除 3 项后，基于 Rasch 的 9 项 BARQ-R 没有不拟合的项目，项目的层次结构符合临床预期，3 名（0.48%）不拟合的个体，个体平均位置：-0.62±1.03 对数单位（最大-0.53，最小 0.72 对数单位），最小的地板效应（1.93%）和天花板效应（0.48%），没有 DIF，PSR=0.72。在 5 对项目中发现了 LID。PCAR 的特征值为 2.18。在 152 名有肌肉骨骼疼痛的成年人（平均年龄 52.26±16.13 岁）的二次 Rasch 分析中，表明在重新评分 2 项后，BARQ-R 没有不拟合的项目，只有 2 名（1.32%）不拟合的个体，良好的目标定位（个体平均位置：-0.36±0.88 对数单位），最小的地板效应（0.01%），没有天花板效应（0.00%），PSR=0.75。在 6 对项目中发现了 LID。PCAR 的特征值为 2.47。
BARQ-R 具有良好的项目和个体拟合度。PSR 与涵盖有限对数单位范围的项目一起表明，身体意识的不同水平仅以适度的精度进行测量。添加和修改项目以涵盖更广泛的身体意识范围，并更好地解决内部身体意识和身体运动的概念，将提高 BARQ-R 的效用。在研究或临床应用之前，还需要进一步分析。此外，还需要在其他身体意识缺陷人群中，如中风或脊髓损伤，进行 BARQ-R 的 Rasch 验证。
