Disturbed body perception may play a role in the aetiology of chronic low back pain (LBP). The Fremantle Back Awareness Questionnaire (FreBAQ) is currently the only self-report questionnaire to assess back-specific body perception in individuals with LBP.
To perform a cross-cultural adaptation of the FreBAQ into Dutch.
Psychometric study.
A Dutch version of the FreBAQ was generated through forward-backward translation, and was completed by 73 patients with LBP and 73 controls to assess discriminant validity. Structural validity was assessed by principal component analysis. Internal consistency was assessed by the Cronbach's alpha coefficient. Construct validity was assessed by examining the relationship with clinical measures (Numerical Rating Scale pain, Oswestry Disability Index (ODI), Tampa Scale for Kinesiophobia). Test-retest reliability was assessed in a subgroup (n = 48 with LBP and 48 controls) using intraclass correlation coefficients (ICC), standard error of measurement (SEM) and minimal detectable change (MDC 95%) RESULTS: The Dutch FreBAQ showed one component with eigenvalue >2. Cronbach's alpha values were respectively 0.82 and 0.73 for the LBP and control group. ICC values were respectively 0.69 and 0.70 for the LBP and control group. In the LBP group, the SEM was 3.9 and the MDC (95%) was 10.8. The LBP group (ODI 22 ± 21%) scored significantly higher on the Dutch FreBAQ than the control group (ODI 0%) (11 ± 7 vs. 3 ± 9, p < 0.001). Within the LBP group, higher Dutch FreBAQ scores correlated significantly with higher ODI scores (rho = 0.30, p = 0.010), although not with pain (rho = 0.10, p = 0.419) or kinesiophobia (r = 0.14, p = 0.226).
The Dutch version of the FreBAQ can be considered as unidimensional and showed adequate internal consistency, sufficient test-retest reliability and adequate discriminant and construct validity in individuals with and without LBP. It can improve our understanding on back-specific perception in the Dutch-speaking population with LBP.
身体感知障碍可能在慢性下背痛（LBP）的发病机制中起作用。Fremantle 背部感知问卷（FreBAQ）是目前唯一评估 LBP 患者背部特定身体感知的自我报告问卷。
将 FreBAQ 进行跨文化适应，转化为荷兰语版本。
心理测量研究。
通过正向-反向翻译生成 FreBAQ 的荷兰语版本，并由 73 名 LBP 患者和 73 名对照者完成，以评估判别效度。结构效度通过主成分分析进行评估。内部一致性通过 Cronbach's alpha 系数进行评估。通过考察与临床测量（数字评分法疼痛、Oswestry 残疾指数（ODI）、坦帕运动恐惧量表）的关系来评估结构效度。在一个亚组（n=48 名 LBP 患者和 48 名对照者）中使用组内相关系数（ICC）、测量误差的标准误差（SEM）和最小可检测变化（MDC 95%）评估测试-重测信度。
荷兰语 FreBAQ 显示出一个特征值>2 的分量。LBP 组和对照组的 Cronbach's alpha 值分别为 0.82 和 0.73。LBP 组和对照组的 ICC 值分别为 0.69 和 0.70。在 LBP 组中，SEM 为 3.9，MDC（95%）为 10.8。LBP 组（ODI 22±21%）的荷兰语 FreBAQ 评分显著高于对照组（ODI 0%）（11±7 对 3±9，p<0.001）。在 LBP 组中，较高的荷兰语 FreBAQ 评分与较高的 ODI 评分显著相关（rho=0.30，p=0.010），尽管与疼痛（rho=0.10，p=0.419）或运动恐惧（r=0.14，p=0.226）无关。
荷兰语版 FreBAQ 可视为单维的，在有和没有 LBP 的个体中表现出足够的内部一致性、足够的测试-重测信度、足够的判别和结构效度。它可以提高我们对荷兰语人群中特定于背部的感知的理解。
