The purpose of present study was to investigate important measurement properties of the Body Awareness Rating Questionnaire (BARQ) subscales: Function; Mood; Feelings; and Awareness. Samples of 50 patients with prolonged musculoskeletal pain and psychosomatic disorders, and 50 gender and age-matched healthy persons participated in the study. Relative (ICC 2,1) and absolute reliability (S(w)) were calculated. Construct validity was examined by testing hypothesis using Pearson (r) or Spearman rank (r(s)) correlation. Discriminate ability was examined using a receiver operating characteristic (ROC) curve, the area under the curve (aROC) being the measure of discriminative validity. All patients reported more or less improvement after treatment, using the Patient Global Impression of Change (PGIC) as an external indicator of important change. Responsiveness to important change was therefore examined by one-way repeated measures analysis of variance (ANOVA), relating change scores of BARQ subscales to the PGIC categories. Relative and absolute reliability values were within recommended limits for all four subscales. Construct and discriminate validity was indicated for Function, Feelings and Awareness, but not for Mood. Responsiveness was indicated for the subscales Function and Awareness, but not for Feelings and Mood. Further research is needed to complement the subscales of BARQ, found with appropriate measurement properties.
本研究的目的是探讨身体意识评定问卷（BARQ）分量表的重要测量特性：功能；情绪；感觉；和意识。50 名患有慢性肌肉骨骼疼痛和身心障碍的患者和 50 名性别和年龄匹配的健康人参加了这项研究。相对（ICC 2,1）和绝对可靠性（S（w））进行了计算。使用 Pearson（r）或 Spearman 等级（r（s））相关来检验假设，以检验结构效度。使用受试者工作特征（ROC）曲线来检验区分能力，曲线下面积（aROC）是区分有效性的度量。所有患者在治疗后或多或少都报告了改善，使用患者整体印象变化（PGIC）作为重要变化的外部指标。因此，通过单向重复测量方差分析（ANOVA），将 BARQ 分量表的变化分数与 PGIC 类别相关联，来检验对重要变化的反应性。所有四个分量表的相对和绝对可靠性值均在推荐范围内。功能、感觉和意识的结构和区分效度得到了证实，但情绪和感觉没有。功能和意识分量表的反应性得到了证实，但感觉和情绪分量表没有。需要进一步研究来补充具有适当测量特性的 BARQ 分量表。
