脑瘫（CP）是儿童身体残疾的最常见原因，通常与继发性肌肉骨骼疼痛有关。脑瘫是一种异质性疾病，运动和认知能力存在很大差异。尽管存在疼痛量表，但仍然需要一种经验证的具有高临床实用性的慢性疼痛评估工具，用于有和无认知障碍的异质性患者人群。本研究的目的是初步评估的12项修订的简明疼痛量表（BPI）的疼痛干扰分量表作为代理报告工具，在一个异质性样本的儿童CP与认知功能障碍和不。参与者（n = 167; 47%为男性;平均年龄= 9.1岁）在痉挛治疗前通过护理人员报告在诊所完成疼痛评估（对于一个亚组，术后重复改良的BPI）。为了测量同时有效性，我们获得了疼痛强度等级（疼痛数字评定量表）和疼痛强度、持续时间和频率评分（达尔豪西疼痛访谈）。改良的BPI评分内部一致（Cronbach α = 0.96），并与数字评定量表强度评分显著相关（rs = 0.67，P < 0.001），达尔豪西疼痛访谈疼痛强度（rs = 0.65，P < 0.001）、疼痛频率（rs = 0.56，P = 0.02）和疼痛持续时间评分（rs = 0.42，P = 0.006）。痉挛治疗后改良BPI评分也显著降低（前测[评分0-10; 3.27 ± 2.84]，后测[2.27 ± 2.68]; t（26）= 2.14，95%置信区间[0.04-1.95]，P = 0.04）。总的来说，修改后的BPI产生的分数具有很强的内部一致性，并同时作为代理报告工具与CP儿童的有效性。
Cerebral palsy (CP) is the most common cause of physical disability in children and is often associated with secondary musculoskeletal pain. Cerebral palsy is a heterogeneous condition with wide variability in motor and cognitive capacities. Although pain scales exist, there remains a need for a validated chronic pain assessment tool with high clinical utility for use across such a heterogeneous patient population with and without cognitive impairment. The purpose of this study was an initial assessment of several psychometric properties of the 12-item modified brief pain inventory (BPI) pain interference subscale as a proxy-report tool in a heterogeneous sample of children with CP with and without cognitive impairment. Participants (n = 167; 47% male; mean age = 9.1 years) had pain assessments completed through caregiver report in clinic before spasticity treatment (for a subgroup, the modified BPI was repeated after procedure). To measure concurrent validity, we obtained pain intensity ratings (Numeric Rating Scale of pain) and pain intensity, duration, and frequency scores (Dalhousie Pain Interview). Modified BPI scores were internally consistent (Cronbach α = 0.96) and correlated significantly with Numeric Rating Scale intensity scores (rs = 0.67, P < 0.001), Dalhousie Pain Interview pain intensity (rs = 0.65, P < 0.001), pain frequency (rs = 0.56, P = 0.02), and pain duration scores (rs = 0.42, P = 0.006). Modified BPI scores also significantly decreased after spasticity treatment (pretest [scored 0–10; 3.27 ± 2.84], posttest [2.27 ± 2.68]; t (26) = 2.14, 95% confidence interval [0.04–1.95], P = 0.04). Overall, the modified BPI produced scores with strong internal consistency and that had concurrent validity as a proxy-report tool for children with CP.
