To date there are only two validations on the Chronic Acquired Polyneuropathy Patient‐Reported Index (CAPPRI) questionnaire, both originated from the North America. We sought to translate and validate CAPPRI for use in Serbian patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We included 109 CIDP patients. CAPPRI, short form (36) health survey (SF‐36), Medical Research Council Sum Score (MRC‐SS), Inflammatory Neuropathy Cause and Treatment (INCAT) sensory and disability scores, Beck Depression Inventory (BDI), and Krupp's Fatigue Severity Scale (FSS) were used. Serbian CAPPRI questionnaire was understandable and the language was appropriate and simple. Calculation demonstrated good person (0.9) and item (0.9) reliability with adequate item (4.1), and person (2.9) separation indices. There was a minor floor effect (13.8%), and no ceiling effect. All items had good fit, except items 2 (pain), 5 (sleeping), and 14 (eating) to some degree. Category responses were well ordered and organized, except item 14 (eating). The CAPPRI score did not vary regarding gender, age, or education. Patients with worse scores on MRC‐SS, INCAT sensory score, INCAT disability score, FSS, and BDI had worse scores on CAPPRI (P < .01). The CAPPRI score showed strong correlation with the SF‐36 score (rho = −0.76, P < .01). The Serbian version of the CAPPRI is reliable and valid patient‐reported index for patients with CIDP, able to differentiate between levels of impairment and disability in this disease.

慢性炎症性脱髓鞘性多发性神经根神经病的慢性获得性多发性神经病患者报告指数（CAPPRI）。

迄今为止，在慢性获得性多发性神经病患者报告指数（CAPPRI）调查表中只有两次验证，均来自北美。我们试图翻译和验证CAPPRI用于塞尔维亚患有慢性炎性脱髓鞘性多发性神经根神经病（CIDP）的患者。我们纳入了109名CIDP患者。CAPPRI，简短形式（36）健康调查（SF‐36），医学研究理事会总分（MRC‐SS），炎性神经病原因和治疗（INCAT）感官和残疾得分，贝克抑郁量表（BDI）和克虏伯疲劳强度使用量表（FSS）。塞尔维亚语CAPPRI问卷是可以理解的，并且语言适当且简单。计算表明，良好的人员（0.9）和人员（0.9）的可靠性以及足够的人员（4.1）和人员（2.9）的分离指数。地板效应很小（13.8％），而没有天花板效应。除了项目2（疼痛），项目5（睡眠）和项目14（饮食）外，所有项目都具有良好的契合度。除项目14（饮食）外，类别回复的命令井井有条，井井有条。CAPPRI分数在性别，年龄或受教育程度方面没有变化。MRC-SS，INCAT感觉评分，INCAT残疾评分，FSS和BDI评分较差的患者的CAPPRI评分较差（P  <.01）。CAPPRI评分与SF‐36评分密切相关（rho = −0.76，P  <.01）。CAPPRI的塞尔维亚语版本对于CIDP患者是可靠且有效的患者报告指数，能够区分该疾病的损伤程度和残疾程度。
