There is evidence to suggest that assessing back-specific altered self-perception may be useful when seeking to understand and manage low back pain (LBP). The Fremantle Back Awareness Questionnaire (FreBAQ) is a patient-reported measure of back-specific body perception that has never been adapted and psychometrically analysed in Italian. Hence, the objectives of this research were to cross-culturally adapt and validate the Italian version of this outcome measure (namely, the FreBAQ-I), to make it available for use with Italians suffering from chronic LBP.
The FreBAQ-I was developed by forward and backward translation, review by a committee skilled in patient-reported measures and test of the pre-final version to assess its clarity, acceptability, and relevance. The statistical analyses examined: structural validity based on Rasch analysis; hypotheses testing by investigating correlations of the FreBAQ-I with the Roland Morris Disability Questionnaire (RMDQ), a pain intensity numerical rating scale (PI-NRS), the Pain Catastrophising Scale (PCS), and the Tampa Scale of Kinesiophobia (TSK) (Pearson's correlations); reliability by internal consistency (Cronbach's alpha) and test-retest repeatability (intraclass correlation coefficient, ICC (2,1)); and measurement error by determining the minimum detectable change (MDC). After the development of a consensus-based translation of the FreBAQ-I, the new outcome measure was delivered to 100 people with chronic LBP.
Rasch analysis confirmed the substantial unidimensionality and the structural validity of the FreBAQ-I. Hypothesis testing was considered good as at least 75% of the hypotheses were confirmed; correlations: RMDQ (r = 0.35), PI-NRS (r = 0.25), PCS (r = 0.41) and TSK (r = 0.38). Internal consistency was acceptable (alpha = 0.82) and test-retest repeatability was excellent (ICC (2,1) = 0.88, 95% CI: 0.83, 0.92). The MDC corresponded to 6.7 scale points.
The FreBAQ-I was found to be a unidimensional, valid, and reliable outcome measure in Italians with chronic LBP. Its application is advised for clinical and research use within the Italian speaking community.
有证据表明，评估背部特定的自我感知改变可能有助于理解和管理下腰痛（LBP）。Fremantle 背部感知问卷（FreBAQ）是一种患者报告的背部身体感知测量工具，从未在意大利进行过适应性和心理测量学分析。因此，本研究的目的是跨文化适应和验证该结果测量的意大利版本（即 FreBAQ-I），使其可用于患有慢性 LBP 的意大利人。
通过正向和反向翻译、由精通患者报告测量的委员会进行审查以及预终版测试来开发 FreBAQ-I，以评估其清晰度、可接受性和相关性。统计分析包括：基于 Rasch 分析的结构有效性；通过调查 FreBAQ-I 与 Roland Morris 残疾问卷（RMDQ）、疼痛强度数字评分量表（PI-NRS）、疼痛灾难化量表（PCS）和坦帕运动恐惧量表（TSK）的相关性来检验假设（皮尔逊相关）；通过内部一致性（克朗巴赫α）和测试-重测重复性（组内相关系数，ICC（2,1））来评估可靠性；通过确定最小可检测变化（MDC）来评估测量误差。在 FreBAQ-I 的基于共识的翻译达成一致后，将新的结果测量方法提供给 100 名患有慢性 LBP 的人。
Rasch 分析证实了 FreBAQ-I 的实质性单维性和结构有效性。假设检验被认为是良好的，因为至少有 75%的假设得到了证实；相关性：RMDQ（r=0.35）、PI-NRS（r=0.25）、PCS（r=0.41）和 TSK（r=0.38）。内部一致性可接受（α=0.82），测试-重测重复性极好（ICC（2,1）=0.88，95%CI：0.83，0.92）。MDC 对应于 6.7 个刻度点。
在患有慢性 LBP 的意大利人中，FreBAQ-I 被发现是一种具有单一维度、有效性和可靠性的结果测量工具。建议在意大利语社区的临床和研究中使用。
