Pain measurement: a comparison using horizontal and vertical visual analogue scales

Area of Science:

• Pain assessment
• Psychometrics
• Clinical evaluation

Background:

• The McGill Pain Questionnaire (MPQ) is a comprehensive pain assessment tool.
• The Short-Form McGill Pain Questionnaire (SF-MPQ) was created to reduce administration time.
• The SF-MPQ includes a visual analogue scale (VAS), unlike the original MPQ.

Purpose of the Study:

• To evaluate the relationship between SF-MPQ scores and both horizontal and vertical VAS.
• To determine the optimal presentation of the VAS within the SF-MPQ for pain assessment.

Main Methods:

• The study involved administering the SF-MPQ with both horizontal and vertical VAS.
• Statistical analysis was performed to compare the scores obtained from each VAS format.
• Patient responses were analyzed to assess the correlation between SF-MPQ and VAS scores.

Main Results:

• The study examined the correlation between SF-MPQ scores and both horizontal and vertical VAS.
• Findings indicate how different VAS presentations may influence pain reporting.
• The research provides data on the psychometric properties of the SF-MPQ with varied VAS formats.

Conclusions:

• The study's findings contribute to understanding the nuances of pain measurement using the SF-MPQ.
• Results may inform future revisions or best practices for utilizing the SF-MPQ and its VAS component.
• Optimizing VAS presentation can enhance the accuracy and efficiency of pain assessment.
