Insights
The new Conceptualization of Pain Questionnaire (COPAQ) effectively measures children's pain concepts. This reliable tool aids in tracking pain perception and evaluating treatment outcomes in pediatric chronic pain management.
Area of Science:
- Pediatric Psychology
- Pain Management
- Psychometrics
Background:
- Childhood chronic pain significantly impacts quality of life.
- Understanding children's pain concepts is crucial for effective management.
- Validated instruments are needed to track pain perception changes and treatment efficacy.
Purpose of the Study:
- To develop a questionnaire assessing children's concepts of pain.
- To evaluate the psychometric properties of the new instrument.
- To establish a reliable measure for pediatric pain research.
Main Methods:
- Cross-sectional, mixed-method study with 324 participants (ages 8-17).
- Developed and administered the Conceptualization of Pain Questionnaire (COPAQ).
- Utilized Rasch modeling for calibration and psychometric evaluation, including fit statistics and Person Separation Index (PSI).
Main Results:
- The COPAQ demonstrated good fit to the Rasch model.
- Targeting analysis identified easily answerable items.
- Internal consistency was strong with a PSI of 0.814.
- 9.56% of participants were identified as responding erratically.
Conclusions:
- The COPAQ is a user-friendly and reliable measure for assessing children's pain concepts.
- The questionnaire exhibits good psychometric properties, including validity and internal consistency.
- COPAQ is suitable for monitoring pain perception and treatment effectiveness in pediatric populations.
Abstract:
(1) Background: Research has shown that thoughts about pain are important for the management of chronic pain in children. In order to monitor changes in thoughts about pain over time and evaluate the efficacy of treatments, we need valid and reliable measures. The aims of this study were to develop a questionnaire to assess a child's concept of pain and to evaluate its psychometric properties; (2) Methods: This is a cross-sectional, two-phase, mixed-method study. A total of 324 individuals aged 8 to 17 years old responded to the newly created questionnaire. The Conceptualization of Pain Questionnaire (COPAQ) was calibrated using the Rasch model. The chi-square test was used for the fit statistics. Underfit and overfit of the model were determined and a descriptive analysis of infit and outfit was conducted to identify who responded erratically. Internal consistency was measured using the Person Separation Index (PSI); (3) Results: Fit to the Rasch model was good. Suitable targeting indicated which items were simple to answer; Person Fit identified 9.56% children who responded erratically; PSI = 0.814; (4) Conclusions: The findings suggest that COPAQ is a measure of a child's concept of pain that is easy to administer and respond to. It has a good fit and a good internal consistency.
