To assess the psychometric properties of the Spanish King's Parkinson's Disease Pain Scale (KPPS). A descriptive transversal study at a Spanish hospital. Fifty-three Parkinson's disease (PD) patients suffering from otherwise explained pain (34 females, age = 63.42 ± 10.52 years, time with disease = 7.25 ± 4.65 years) were evaluated by the KPPS, Brief Pain Inventory (BPI), two Pain Pressure Thresholds (PPTs), Widespread Mechanical Hyperalgesia (WMH), and Conditioned Pain Modulation (CPM). A retest of the KPPS was performed 7-15 days later. Internal consistency, test-retest reliability (intraclass correlation coefficient (ICC)), measurement error, factor structure, and criterion/convergent validity were assessed. Internal consistency of the Spanish KPPS was acceptable (Cronbach's alpha = 0.77). The mean test and retest total KPPS scores were similar (test = 34.83 ± 23.50 points, retest = 35.87 ± 26.23 points), and test-retest reliability was good (ICC = 0.85, 95% CI = 0.75-0.91). Standard error of measurement (SEM) was 9.1 points and smallest detectable change (SDC) was 25.22 points. The sampling adequacy was not sufficient to perform factor analysis. The total KPPS score was not correlated to the BPI intensity subscale ( = 0.18, =0.19), but it was moderately and positively correlated to the interference subscale ( = 0.43, =0.001). The total KPPS was moderately and negatively correlated to both the remote PPT ( = -0.4, =0.003) and WMH ( = -0.38, =0.005). No statistical correlations were found with local PPT or CPM. The present study provides evidence that the Spanish KPPS effectively measures pain in individuals with PD, with its total score demonstrating good reliability, minimal measurement error, and adequate criterion and convergent validity.
评估西班牙版国王帕金森病疼痛量表（KPPS）的心理测量学特性。在一家西班牙医院进行描述性横断面研究。采用KPPS、简明疼痛量表（BPI）、两种疼痛压力阈值（PPT）、广泛机械性痛觉过敏（WMH）和条件性疼痛调制（CPM）对53例患有无法用其他原因解释的疼痛的帕金森病（PD）患者（34例女性，年龄=63.42±10.52岁，患病时间=7.25±4.65年）进行评估。7至15天后对KPPS进行重测。评估内部一致性、重测信度（组内相关系数（ICC））、测量误差、因子结构以及标准/收敛效度。西班牙版KPPS的内部一致性可接受（克朗巴哈系数α=0.77）。重测和初测的KPPS总分均值相似（初测=34.83±23.50分，重测=35.87±26.23分），重测信度良好（ICC=0.85，95%置信区间=0.75 - 0.91）。测量标准误（SEM）为9.1分，最小可检测变化（SDC）为25.22分。抽样充分性不足以进行因子分析。KPPS总分与BPI强度分量表无相关性（=0.18，=0.19），但与干扰分量表呈中度正相关（=0.43，=0.001）。KPPS总分与远程PPT（= - 0.4，=0.003）和WMH（= - 0.38，=0.005）均呈中度负相关。未发现与局部PPT或CPM存在统计学相关性。本研究提供了证据，表明西班牙版KPPS能有效测量PD患者的疼痛，其总分具有良好的信度、最小测量误差以及充分的标准和收敛效度。
