BACKGROUND
Assessment of function and functional interference is an important component of chronic pain assessment and treatment and is commonly based on self-report questionnaires. Existing questionnaires for assessing functional interference are language dependent, which can limit their utility for patients across cultures with literacy, fluency, or cognitive restrictions.
OBJECTIVE
The objectives of this study were to create a tool with minimal language dependence and literacy requirement for measuring functional interference due to chronic pain and evaluate the psychometric properties and usability of this new assessment scale, the Pictorial Pain Interference Questionnaire (PPIQ), in a clinical sample of participants with chronic pain.
DESIGN
The study employed a prospective, cross-sectional design in a clinical chronic pain setting.
PARTICIPANTS AND METHODS
A total of 113 participants with chronic non-cancer pain were recruited from a private chronic pain clinic. A pictorial scale was developed and tested via psychometric procedures, including comparisons with validated measures of functional interference and related chronic pain constructs.
RESULTS
Excellent internal consistency reliability (=0.91), good construct validity (total score: =0.72-0.81), and adequate-to-good convergent and discriminant validities were demonstrated through comparative analyses with existing self-report questionnaires. A scoring metric for classifying low, moderate, and high levels of interference was found to have good construct validity. Evaluation of satisfaction revealed adequate understanding of the PPIQ among most users.
CONCLUSION
Initial support for the PPIQ as an alternative to language-based questionnaires for assessing functional interference from chronic pain was found. Subsequent research will help to clarify psychometric properties of the PPIQ and user response among various chronic pain subgroups.
背景
功能及功能干扰评估是慢性疼痛评估与治疗的重要组成部分，通常基于自我报告问卷。现有的评估功能干扰的问卷依赖语言，这可能会限制其对有读写能力、语言流利程度或认知受限的不同文化背景患者的效用。
目的
本研究的目的是创建一种对语言依赖和读写要求最低的工具，用于测量慢性疼痛引起的功能干扰，并在慢性疼痛参与者的临床样本中评估这种新的评估量表——图像疼痛干扰问卷（PPIQ）的心理测量特性和可用性。
设计
本研究在临床慢性疼痛环境中采用前瞻性横断面设计。
参与者和方法
从一家私立慢性疼痛诊所招募了113名患有慢性非癌性疼痛的参与者。通过心理测量程序开发并测试了一种图像量表，包括与功能干扰及相关慢性疼痛结构的有效测量方法进行比较。
结果
通过与现有自我报告问卷的比较分析，证明了其具有出色的内部一致性信度（=0.91）、良好的结构效度（总分：=0.72 - 0.81）以及充分至良好的聚合效度和区分效度。发现一种用于分类低、中、高水平干扰的评分指标具有良好的结构效度。满意度评估显示大多数用户对PPIQ有充分的理解。
结论
发现PPIQ初步支持作为一种替代基于语言的问卷来评估慢性疼痛引起的功能干扰。后续研究将有助于阐明PPIQ的心理测量特性以及不同慢性疼痛亚组中的用户反应。
