Chronic pain is a complex phenomenon. Understanding its multiple dimensions requires the use of a combination of several patient-reported outcome measures (PROMs). However, completing multiple PROMs is time-consuming and can be a burden for patients. The objective of our study was to simultaneously reduce the French versions of the Pain Catastrophizing Scale (PCS) and Tampa Scale for Kinesiophobia (TSK) questionnaires to enable their use in an ambulatory and clinical settings.
We conducted a clinical study between May 2014 and August 2020 in our rehabilitation center. 1428 chronic musculoskeletal pain patients (CMSP) were included. The originality of our approach is that the reduction method included qualitative as well as quantitative analyses. The study was divided into two parts: 1) reduction of the questionnaires (n=1363) based on internal consistency (item-to-total correlation), principal component analysis (item loadings), Rasch analysis (infit/outfit), floor and ceiling effect (quantitative analyses) and expert judgment of items (qualitative analysis), and 2) validation of the reduced questionnaires (n=65), including test-retest reliability (intraclass correlation coefficient [ICC]), homogeneity (Cronbach α), criterion validity (Pearson correlation [r] with the long-version score), determination of the pathological cutoff and Minimal Clinically Important Difference (MCID). The two full-length questionnaires include 30 items in total.
The reduction resulted in a 5-item PCS (score 0-20) and 6-item TSK (score 0-24). Psychometric properties of the reduced questionnaires were all acceptable as compared with other version (α=0.89 and 0.71, ICC=0.75 and 0.60, r=0.86 and 0.70, MCID=2 and 2 for PCS and TSK, respectively) while keeping the structure and coherence of the long versions.
The two reduced versions of the PCS and TSK can be used in CMSP patient. As their administration only requires a few minutes, they can be implemented in outpatient consultation as well as in clinical settings.
慢性疼痛是一种复杂的现象。要理解其多个维度，需要使用多种患者报告结局测量指标（PROMs）。然而，完成多个PROMs很耗时，且可能给患者带来负担。我们研究的目的是同时简化疼痛灾难化量表（PCS）和坦帕运动恐惧量表（TSK）问卷的法语版本，以便能在门诊和临床环境中使用。
我们于2014年5月至2020年8月在我们的康复中心进行了一项临床研究。纳入了1428例慢性肌肉骨骼疼痛患者（CMSP）。我们方法的独特之处在于简化方法包括定性和定量分析。该研究分为两个部分：1）基于内部一致性（项目与总分相关性）、主成分分析（项目负荷）、拉施分析（内拟合/外拟合）、地板效应和天花板效应（定量分析）以及项目的专家判断（定性分析）对问卷进行简化（n = 1363）；2）对简化后的问卷进行验证（n = 65），包括重测信度（组内相关系数[ICC]）、同质性（Cronbach α）、效标效度（与长版本分数的皮尔逊相关系数[r]）、确定病理临界值和最小临床重要差异（MCID）。这两个全长问卷总共包括30个项目。
简化后得到了一个5项的PCS（得分0 - 20）和一个6项的TSK（得分0 - 24）。与其他版本相比，简化后问卷的心理测量学特性均可以接受（PCS和TSK的α分别为0.89和0.71，ICC分别为0.75和0.60，r分别为0.86和0.70，MCID分别为2和2），同时保持了长版本的结构和连贯性。
简化后的PCS和TSK两个版本可用于CMSP患者。由于其施测仅需几分钟，它们可在门诊咨询以及临床环境中实施。
