Trial Outcomes & Findings for Pain, Inflammation and Opioid Craving (NCT NCT04190563)

NCT ID: NCT04190563

Last Updated: 2026-08-13

Results Overview

Investigators will assess opioid craving using the Opioid Craving Scale, a participant-reported measure of opioid craving. This is a continuous measure that is quantified as a total scale score representing an average of the 3 items, with a range from 0-10, with higher scores reflecting more craving. This outcome is the mean score at a single time point, immediately following completion of the intervention.

Measure
Pain Education
Brief behavioral education on pain. This includes a standardized script providing basic education on pain and responses to pain and an acute induction of pain. Pain Education: Experimenter-administered education.
Pain De-Catastrophizing
Brief behavioral education on how to modify the interpretation of pain. This includes a standardized script, a scripted practice application and application of the skill during an acute pain induction. Pain De-Catastrophizing: Experimenter-administered education and skill practice.
