PREventing Pain After Surgery (PREPS)

August 17, 2026 updated by: Samantha Meints, Brigham and Women's Hospital

PREventing Pain After Surgery: A Feasibility and Acceptability Study of Acceptance and Commitment Therapy for the Prevention of Chronic Post-surgical Pain (PREPS)

The present study aims to adapt and modify a brief presurgical Acceptance and Commitment Therapy (ACT) intervention aimed at preventing the transition to Chronic Post-Surgical Pain (CPSP) and reducing long-term opioid use. Investigators will then assess the acceptability, feasibility, and preliminary efficacy of the finalized intervention to prevent the transition to CPSP and reduce post-surgical opioid use six months following lumbar spine surgery. Finally, investigators will identify psychosocial and psychophysical phenotypes associated with response to this intervention.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.

Participants assigned to this arm will receive treatment as usual.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Treatment Helpfulness
Time Frame: Immediately following the ACT workshop
Treatment Helpfulness Questionnaire (THQ); Item assesses the perceived helpfulness of the ACT workshop and is rated from -5 (extremely harmful) to 5 (extremely helpful).
Immediately following the ACT workshop

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
