Trial Outcomes & Findings for Stress Response in Opioid Use Disorder (NCT NCT03616379)

NCT ID: NCT03616379

Last Updated: 2024-04-01

Results Overview

Negative affect will be measured using the Negative Affect Subscale of the Positive and Negative Affect Schedule. This is a 10-item self-report measure on which respondents rate how strongly they are experiencing negative emotion. The range of scores is 10-50, with higher scores representing higher negative affect.

Measure
Psychoeducational Control
Psychoeducational Control: The Psychoeducational Control condition will consist of a brief script describing the body's response to stress and will not discuss cognition or the role of interpretation or affect labeling during stress.
Affect Regulation Condition
Affect Regulation: In the Affect Regulation Condition, participants will be provided instructions for how to reappraise negative thoughts in the context of stress by developing statements consistent with more benign interpretations of stress (e.g., This won't last forever.).
Affect Labelling Condition
Affect Labelling: In the Affect Labeling Condition, participants will be provided with instructions for how to verbalize their emotional response during the stressor.

PRIMARY outcome

Timeframe: Time-to-event outcome; during this 1-session study, this will measure time to outcome (discontinuation of task) from time of initiation of the stress induction task up to a maximum of 15 minutes later.

Distress tolerance will be measured using the Computerized Mirror Tracing Persistence Task. This is a computer-based task in which participants trace a mirror on the screen using the cursor. Participants are asked to persist at the task for as long as possible. Time to discontinuation is used as a measure of distress tolerance (in seconds). Longer duration reflects better tolerance of distress.

SECONDARY outcome

Timeframe: Change measured over 2 time points during this 1-session study (from start of stress induction task to 30 minutes after completion; approximately 40-45 minutes).

Population: Values more than 3 standard deviations from the mean were excluded.

Cortisol levels will be measured using saliva samples. Salivary cortisol levels are measured on a continuous scale (micrograms/deciliter).

SECONDARY outcome

Timeframe: Change measured over 2 time points during this 1-session study (prior to and during the stress induction task; approximately 10-15 minutes).

Population: Participants with data missing due to technical issues with data collection were excluded.

Skin conductance level is a physiological outcome that will be measured using electrodes placed on participants fingers, connected to a Biopac MP150 system with an ECG amplifier. Change will be measures by subtracting the maximum value during the stress task from the value at the end of a baseline recording.

Self-report of opioid craving will be measured using the Opioid Craving Scale, a 3-item measure, with a range of 0-30, with higher scores representing strong opioid craving.
