To culturally adapt the Craniofacial Pain and Disability Inventory (CF-PDI) for a Brazilian population and to assess its psychometric properties, including internal consistency, reliability, and construct and structural validity.
A total of 100 female and male TMD patients with temporomandibular disorders (TMD), with or without headaches, were included. Participants were assessed based on the Research Diagnostic Criteria for TMD and the International Headache Society criteria. For statistical analyses, intraclass correlation coefficient (ICC) was used for assessing reliability (test-retest), Cronbach's alpha for internal consistency, Pearson rank correlation for construct validity, and confirmatory factor analysis (CFA) for structural validity.
The CFA provided the following three factors/domains for the Brazilian CF-PDI (CF-PDI/Br): (1) functional and psychosocial limitation; (2) pain; and (3) frequency of comorbidities. Scores for test-retest reliability and internal consistency in each domain were acceptable (ICC > 0.9; Cronbach's α > 0.77). Correlations between CF-PDI scores and jaw functional limitation, pain-related disability, pain catastrophizing, depression, neck pain-related disability, and kinesiophobia scores were confirmed in 89% (50/56) of the comparisons.
The CF-PDI/Br with three factors had sound psychometric properties. Therefore, the Brazilian Portuguese version can be used in clinical settings and for research purposes.
对 Craniofacial Pain and Disability Inventory（CF-PDI）进行文化调适，使其适用于巴西人群，并评估其心理测量学特性，包括内部一致性、信度、结构和建构效度。
共纳入 100 名患有颞下颌关节紊乱症（TMD）的男女 TMD 患者，包括有或无头痛。根据 TMD 的研究诊断标准和国际头痛协会标准对参与者进行评估。对于统计分析，采用组内相关系数（ICC）评估可靠性（测试-重测），克朗巴赫 α 评估内部一致性，皮尔逊等级相关评估建构效度，验证性因子分析（CFA）评估结构效度。
CFA 为巴西 CF-PDI（CF-PDI/Br）提供了以下三个因素/领域：（1）功能和心理社会限制；（2）疼痛；（3）共病频率。各领域的测试-重测信度和内部一致性得分可接受（ICC>0.9；克朗巴赫 α>0.77）。CF-PDI 评分与下颌功能限制、与疼痛相关的残疾、疼痛灾难化、抑郁、颈部疼痛相关残疾和运动恐惧评分之间的相关性在 89%（50/56）的比较中得到证实。
具有三个因素的 CF-PDI/Br 具有良好的心理测量学特性。因此，巴西葡萄牙语版本可用于临床和研究目的。
