Many musculoskeletal pain conditions are characterized by hypersensitivity, which is induced by central sensitization (CS). A questionnaire, the Central Sensitization Inventory (CSI), was recently developed to help clinicians identify patients whose presenting symptoms may be related to central sensitivity syndrome (CSS). The aims of the present study were to examine criterion validity and construct validity of the Japanese version of the CSI (CSI-J), and to investigate prevalence rates of CS severity levels in patients with musculoskeletal disorders.
Translation of the CSI into Japanese was conducted using a forward-backward method. Two hundred and ninety patients with musculoskeletal pain disorders completed the resultant CSI-J. A subset of the patients (n = 158) completed the CSI-J again one week later. The relationships between CSI and clinical symptoms, EuroQol 5-dimension (EQ-5D) and Brief Pain Inventory (BPI), were examined for criterion validity. EQ-5D assesses Health-related QOL and BPI measures pain intensity and pain interference. The psychometric properties were evaluated with analyses of construct validity, factor structure and internal consistency, and subsequently investigate the prevalence rates of CS severity levels.
The CSI-J demonstrated high internal consistency (Cronbach's α = 0.89) and test-retest reliability was excellent value (ICC = 0.85). The CSI-J was significantly correlated with EQ-5D (r = -0.44), pain intensity (r = 0.42), and pain interference (r = 0.48) (p < 0.01 for all). Ten percent of the participants were above the cutoff "40". The exploratory factor analysis resulted in 5-factor model.
This study reported that the CSI-J was a useful and psychometrically sound tool to assess CSS in Japanese patients with musculoskeletal disorders. The finding of the prevalence rates of CS severity levels in patients with musculoskeletal disorders may help clinicians to decide strategy of treatment.
许多肌肉骨骼疼痛疾病的特征是敏感性过高，这是由中枢敏化（CS）引起的。最近开发了一种问卷，即中枢敏化量表（CSI），以帮助临床医生识别其表现症状可能与中枢敏感综合征（CSS）相关的患者。本研究的目的是检验 CSI-J 的效标效度和结构效度，并调查肌肉骨骼疾病患者 CS 严重程度水平的患病率。
使用正向-反向翻译法将 CSI 翻译成日语。290 名患有肌肉骨骼疼痛疾病的患者完成了由此产生的 CSI-J。其中一部分患者（n=158）在一周后再次完成了 CSI-J。为了检验效标效度，对 CSI 与临床症状、EuroQol 5 维度（EQ-5D）和简明疼痛量表（BPI）之间的关系进行了检验。EQ-5D 评估健康相关生活质量，BPI 测量疼痛强度和疼痛干扰。通过结构效度、因子结构和内部一致性分析评估心理测量特性，随后调查 CS 严重程度水平的患病率。
CSI-J 具有较高的内部一致性（Cronbach's α=0.89），重测信度极好（ICC=0.85）。CSI-J 与 EQ-5D（r=-0.44）、疼痛强度（r=0.42）和疼痛干扰（r=0.48）显著相关（p<0.01）。10%的参与者超过了“40”的临界值。探索性因子分析产生了 5 因素模型。
本研究报告称，CSI-J 是一种有用且具有良好心理测量特性的工具，可用于评估日本肌肉骨骼疾病患者的 CSS。肌肉骨骼疾病患者 CS 严重程度水平的患病率可能有助于临床医生决定治疗策略。
