Behavioural evaluation in patients affected by chronic pain: a preliminary study

Area of Science:

• Pain Management
• Clinical Nursing
• Behavioral Science

Background:

• Assessing chronic pain involves subjective patient reports and objective behavioral observations.
• The Verbal Numerical Scale (VNS) captures patient-reported pain intensity.
• The Pain Behaviour Rating Scale (UAB) quantifies observable pain behaviors.

Purpose of the Study:

• To analyze the relationship between subjective pain evaluation (VNS) and objective behavioral measures (UAB).
• To determine if VNS and UAB provide complementary or interchangeable pain assessment data.
• To enhance the understanding of chronic non-malignant pain assessment in a clinical setting.

Main Methods:

• Observational correlation study conducted in a hospital setting.
• Inclusion of 61 patients with various forms of non-malignant chronic pain.
• Pain behaviors were systematically observed and recorded by nursing staff using the UAB scale.

Main Results:

• A positive, moderate correlation was observed between the Verbal Numerical Scale (VNS) and the Pain Behaviour Rating Scale (UAB) (r=0.29, p<0.0001).
• The findings suggest that subjective pain reports and observed behaviors are related but distinct indicators.
• Neither method alone is sufficient for a complete pain assessment.

Conclusions:

• Subjective pain reporting (VNS) and behavioral observation (UAB) are complementary, non-interchangeable methods for pain assessment.
• Combining both subjective and objective measures provides a more global and objective portrayal of the patient's pain experience.
• This integrated approach can improve the accuracy and comprehensiveness of chronic pain management strategies.
