An Initial Psychometric Evaluation of the Pain Concepts Questionnaire in a Low-SES Setting

The examination of pain beliefs for chronic pain assessment and treatment has been a growing area of interest. A variety of questionnaires have been developed to assess pain beliefs, however, these questionnaires often require high levels of literacy and education. The pain concepts questionnaire (PCQ) was developed with literacy-adaptations to better evaluate pain beliefs in a low socioeconomic (SES) population. This study is an initial exploratory evaluation of the PCQ in a sample of patients with chronic pain and multiple disparities as part of the learning about my pain (LAMP) trial, a randomized controlled trial comparing literacy-adapted psychosocial treatments for chronic pain. All data were collected at pretreatment. Exploratory factor analysis was performed to examine the underlying factor structure of the PCQ and cross-sectional correlational analyses examined relationships between pain beliefs with sociodemographic factors and chronic pain-related variables. Results suggested a 2-factor solution with a Biopsychosocial factor and Biomedical factor. Consistent with the literature, correlational analyses highlighted racial and SES disparities in pain beliefs and the importance of beliefs in pain- and cognitive/affective-related functioning. The study emphasizes the importance of pain beliefs in chronic pain management and recommends future research to further examine additional psychometric properties of the PCQ. Perspective: This study is an initial evaluation of the psychometric properties of a new measure of chronic pain beliefs, the pain concepts questionnaire (PCQ). The PCQ is literacy-adapted and was assessed within a low-SES population. Psychometric proprieties of this measure were promising and could be useful in pain assessment and interventions.

Automated summary

This study provides an initial evaluation of a new measure of chronic pain beliefs, the pain concepts questionnaire (PCQ), within a low-SES population. The psychometric properties of the PCQ were found to be promising and could be useful in pain assessment and interventions. These results highlight the importance of pain beliefs in chronic pain management and the need for further research in this area.
