Cancer involves numerous physical, psychological and emotional changes and has a negative impact on patients. Although there are a wide variety of questionnaires for general use in patients with cancer, very few are available that assess the pain, disability and craniomandibular functionality of patients with head and neck cancer (HNC) in a more specific manner. The purpose of this study is to present the preliminary behavior of the CF-PDI in its reduced version adapted for patients with HNC.
A total of 61 patients with HNC were included in a study to preliminarily analyze the internal consistency of the instrument, the convergent validity and the floor and ceiling effects. All the patients completed the informed consent document and a battery of 5 questionnaires: The Numerical Rating Scale (NRS), the Tampa Scale for Kinesiophobia for Temporomandibular Disorders (TSK-TMD), the Pain Catastrophizing Scale (PCS), the Quality of Life Questionnaire in patients with HNC (QLQ-HN) and the reduced version of the Craniofacial Pain and Disability Inventory (CF-PDI-11). Patients also performed 2 physical tests: measurements of the pain threshold on the masseter muscle and on the distal phalanx of the first finger; and the maximum mouth opening in neutral head position.
Cronbach's α coefficient showed a very high internal consistency of 0.92. In terms of convergent validity, a statistically significant correlation was found between the CF-PDI-11 and the following variables: NRS, TSK-TMD, PCS, QLQ-HN, the threshold of pain in the distal phalanx of the first finger and the maximum interincisal opening. However, 21.3% of patients obtained the lowest possible score. The strongest correlation was found between the CF-PDI-11 and the QLQ-HN (r = 0.85, p <0.01).
The preliminary version of the CF-PDI-11 shows that it could be a valid and reliable instrument to measure pain, disability and quality of life in patients with HNC.
癌症涉及到许多身体、心理和情感上的变化，对患者产生负面影响。尽管有许多通用的问卷可用于癌症患者，但很少有专门评估头颈部癌症（HNC）患者疼痛、残疾和颅颌功能的问卷。本研究旨在介绍简化版 CF-PDI 在头颈部癌症患者中的初步表现。
共纳入 61 例 HNC 患者，对该工具的内部一致性、收敛效度以及地板和天花板效应进行初步分析。所有患者均完成了知情同意书和一套 5 份问卷：数字评分量表（NRS）、颞下颌关节运动恐惧症 Tampa 量表（TSK-TMD）、疼痛灾难化量表（PCS）、头颈部癌症患者生活质量问卷（QLQ-HN）和简化版颅面疼痛和残疾量表（CF-PDI-11）。患者还进行了 2 项物理测试：测量咬肌和第一指远节的疼痛阈值；以及中立头位下的最大张口度。
Cronbach's α 系数显示出非常高的内部一致性，为 0.92。在收敛效度方面，CF-PDI-11 与以下变量之间存在统计学显著相关性：NRS、TSK-TMD、PCS、QLQ-HN、第一指远节疼痛阈值和最大切牙开口度。然而，21.3%的患者获得了最低可能得分。CF-PDI-11 与 QLQ-HN 之间的相关性最强（r = 0.85，p <0.01）。
简化版 CF-PDI-11 表明，它可能是一种有效且可靠的工具，用于评估 HNC 患者的疼痛、残疾和生活质量。
