Clinical Trial 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.

Intervention

Behavioral:
• Cognitive-Behavioral Intervention
This intervention comprises three components: 1) general education about pain (e.g., pain pathways) and a rationale for the intervention (e.g., gate control theory); 2) impact of positive and negative pain-related thoughts on neural process of pain; and 3) a guided imaginal pain exposure exercise.
• Pain Education
General information about the neurobiology of pain and knee osteoarthritis will be given to participants assigned to this intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain Catastrophizing Scale (PCS) at 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.	Day 2
