About this study
Official title: Neural Mechanisms Underlying Psychosocial Contributions to Ethnic Group Differences in Pain
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.

- Osteoarthritis, Knee

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cognitive-Behavioral InterventionBehavioural
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 EducationBehavioural
General information about the neurobiology of pain and knee osteoarthritis will be given to participants assigned to this intervention.
| Study group | Role | What they receive |
|---|---|---|
| Pain Catastrophizing Reduction Group | Experimental | This group will be assigned to a 30-minute, single-session cognitive-behavioral intervention designed to reduce pain catastrophizing. Receives: Behavioral: Cognitive-Behavioral Intervention |
| Pain Education Group | Active comparator | This group will receive general information about the neurobiology of pain and knee OA. Receives: Behavioral: Pain Education |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Pain Catastrophizing Scale (PCS)
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.'
Measured: Baseline; Day 2

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 May 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Pain Catastrophizing Scale (PCS) (time frame: Baseline; Day 2). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2024.
