Study of Pain Catastrophizing

Not Applicable

Completed

• Conditions: Osteo Arthritis Knee
• Interventions: Behavioral: Pain Education; Behavioral: Cognitive-Behavioral Intervention

• Registration Number: NCT03836586
• Lead Sponsor: University of Florida

Brief Summary

This study proposes to experimentally manipulate pain catastrophizing in order to investigate the neural mechanisms by which pain catastrophizing influences the experience of pain among non-Hispanic Blacks (NHBs) and non- Hispanic Whites (NHWs) with knee osteoarthritis (OA). Therefore, participants will be randomized to either a single session cognitive-behavioral intervention to reduce pain catastrophizing or a pain education control group.

Arm && Interventions

Group	Intervention	Description
Pain Education Group	Pain Education	This group will receive general information about the neurobiology of pain and knee OA.
Pain Catastrophizing Reduction Group	Cognitive-Behavioral Intervention	This group will be assigned to a 30-minute, single-session cognitive-behavioral intervention designed to reduce pain catastrophizing.

Primary Outcome Measures

Name	Time	Method
Pain Catastrophizing Scale (PCS) at Day 2	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.' The PCS total score is computed by summing responses to all 13 items. PCS total scores range from 0 - 52. Higher scores indicate the presence of catastrophizing and therefore worse outcome.
