Summary
This study validated the Chronic Pain Behavioral Pain Scale for Adults (CBPS) against the Numeric Rating Scale (NRS) in chronic pain patients. The CBPS demonstrated acceptable reliability and validity, showing potential as an objective pain assessment tool.
Area of Science:
- Pain Management
- Clinical Assessment
- Psychometrics
Background:
- The Numeric Rating Scale (NRS) is widely used but subjective.
- Objective pain scales are less common in outpatient chronic pain settings.
- Evaluating objective measures is crucial for comprehensive pain assessment.
Purpose of the Study:
- To assess the reliability and validity of the Chronic Pain Behavioral Pain Scale for Adults (CBPS).
- To compare the CBPS with the traditional NRS in adult chronic pain patients.
- To establish an objective pain scale for outpatient use.
Main Methods:
- Cross-sectional study design.
- Patients assessed pre- and post-procedure using CBPS and NRS by a researcher and nurse.
- Analysis of interrater reliability, concurrent validity, and construct validity.
Main Results:
- Fair-good interrater reliability for CBPS (kappa 0.59-0.65).
- Moderate concurrent validity for postprocedure measurements (correlation 0.67-0.68).
- Significant reduction in pain scores (CBPS and NRS) postprocedure (p < 0.001).
Conclusions:
- The CBPS demonstrates interrater reliability, concurrent validity, and construct validity.
- The CBPS shows potential as an objective measure in chronic pain assessment.
- Further research is needed to confirm long-term benefits and effectiveness.

Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...
