Study of Pain Catastrophizing-2 (SPAC-2)

Not Applicable
Completed
Conditions
Osteoarthritis, Knee
Interventions
Behavioral: Cognitive-Behavioral Intervention
Behavioral: Pain Education
Registration Number
NCT04805190
Lead Sponsor
University of Florida
Brief Summary

This study experimentally manipulates pain catastrophizing in order to investigate the neural mechanisms by which pain catastrophizing influences the experience of pain in different ethnic groups among adults with knee osteoarthritis. Participants will be randomized to either a single session cognitive-behavioral intervention to reduce pain catastrophizing or a pain education control group.

Primary Outcome Measures
NameTimeMethod
Change in Pain Catastrophizing Scale (PCS)Baseline; Day 2

13-item scale that assesses catastrophic thinking associated with pain. The study team will administer the PCS using traditional instructions (a measure of trait catastrophizing) and instructions to assess situation-specific catastrophizing ("Thinking back to your experience during the laboratory pain testing"). Thoughts and feelings concerning pain are ranked on a 0-4 scale, with 0 being the patient has this thought/feeling 'not at all' to 4, the patient has this thought feeling 'all the time.'
