The "credibility" and "expectation" regarding the treatment are important factors in the rehabilitation management of patients with spinal pain (SP).
The aim of this study was to translate, culturally adapt, and validate an Italian version of the credibility/expectancy questionnaire (CEQ-I) by Devilly and Borkovec (CEQ) for its application in SP in rehabilitative care.
Cross-sectional observational study.
Ninety-nine patients ( = 99; mean age of 56.9 years ± 16.3 SD) with acute or chronic SP were recruited from September 2023 to September 2024. To evaluate construct validity, exploratory factor analysis (EFA) was conducted using a matrix of polychoric correlations along with promax rotation. The internal consistency and stability of the scale were evaluated using Cronbach's alpha coefficient and test-retest analysis through the intraclass correlation coefficient (ICC). Pearson's analysis between CEQ and other scales (Numeric Rating Scale, NRS; Roland and Morris-Disability Questionnaire, RMDQ; Oswestry Disability Index, ODI; Neuropathic Pain Symptom Inventory, NPSI) was employed to assess external validity.
Ninety-nine subjects were recruited. Test-retest reliability between two consecutive administrations of the CEQ showed an ICC of 0.90 ( < 0.001). The Kaiser-Meyer-Olkin (KMO) statistic was 0.81, indicating suitability for factor analysis. EFA revealed two factors-credibility and expectancy-accounting for 56.6% of the variance. Cronbach's alpha indicated high internal consistency (0.85). External validation using Pearson's correlation found no significant relationships between the CEQ subscale scores and NRS, RMDQ, ODI, and NPSI scales.
The CEQ-I is a valid Italian translation of CEQ that demonstrates acceptable psychometric properties in SP in a rehabilitative setting. However, we recommend further analysis of the construct definition of the CEQ-I.
对于治疗的“可信度”和“期望”是脊柱疼痛（SP）患者康复管理中的重要因素。
本研究的目的是翻译、进行文化调适并验证Devilly和Borkovec的可信度/期望问卷（CEQ）的意大利语版本（CEQ-I），以便将其应用于康复护理中的SP。
横断面观察性研究。
从2023年9月至2024年9月招募了99例急性或慢性SP患者（n = 99；平均年龄56.9岁±16.3标准差）。为评估结构效度，使用多相关系数矩阵并结合promax旋转进行探索性因子分析（EFA）。使用Cronbach's α系数评估量表的内部一致性和稳定性，并通过组内相关系数（ICC）进行重测分析。采用CEQ与其他量表（数字评定量表，NRS；罗兰和莫里斯残疾问卷，RMDQ；奥斯维斯特残疾指数，ODI；神经性疼痛症状量表，NPSI）之间的Pearson分析来评估外部效度。
招募了99名受试者。CEQ连续两次施测之间的重测信度显示ICC为0.90（P < 0.001）。Kaiser-Meyer-Olkin（KMO）统计量为0.81，表明适合进行因子分析。EFA揭示了两个因子——可信度和期望——解释了56.6%的方差。Cronbach's α表明内部一致性较高（0.85）。使用Pearson相关性进行的外部验证发现，CEQ子量表得分与NRS、RMDQ、ODI和NPSI量表之间无显著关系。
CEQ-I是CEQ的有效意大利语翻译版本，在康复环境中的SP中显示出可接受的心理测量特性。然而，我们建议对CEQ-I结构定义进行进一步分析。
