Perioperative ACT for Preventing CPSP (PREPS)

April 27, 2026 updated by: Samantha Meints

Feasibility and Acceptability of a Single-session Perioperative Acceptance and Commitment Therapy (ACT) Workshop for Preventing Chronic Postsurgical Pain: A Single-arm, Non-randomized Pilot Trial

The present study aims to adapt and modify a brief perioperative 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 assess the acceptability, feasibility, and preliminary efficacy of the intervention via a non-randomized, non-controlled pilot trial.

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

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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.

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

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.

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 (THQ)
Time Frame: Immediately following the ACT workshop
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.
Outcome Measure
Measure Description
Time Frame
Treatment Helpfulness (THQ)
Time Frame: 1 month post-op
Item assesses the perceived helpfulness of the ACT workshop and is rated from -5 (extremely harmful) to 5 (extremely helpful).
1 month post-op
Treatment Credibility
Time Frame: immediately following ACT workshop
Credibility and Expectancy Questionnaire (CEQ); 3 items are rated to indicate the logic, success, and confidence in the treatment. Scores are summed with a range from 3-27 where higher scores indicating greater treatment credibility
immediately following ACT workshop
Treatment Expectancy
Time Frame: immediately following ACT workshop
Credibility and Expectancy Questionnaire (CEQ); 3 items are used to assess the likelihood of the success of the therapy to reduce pain and improve function. Scores are summed with a range from 0-29 where higher scores indicate greater expectancy for beneficial treatment outcomes
immediately following ACT workshop
Pain Interference
Time Frame: 1 month post-op
Assesses how much a person's pain impacts their daily activities, including general activity, mood, walking, work, relationships with others, enjoyment of life, and sleep, with higher scores indicating greater interference with daily functioning due to pain. Each of the seven domains is rated on a scale from 0 (no interference) to 10 (complete interference), and the average score across these domains represents the overall pain interference level.
1 month post-op
Pain Interference
Time Frame: 3 months post-op
The Brief Pain Inventory assesses how much a person's pain impacts their daily activities, including general activity, mood, walking, work, relationships with others, enjoyment of life, and sleep, with higher scores indicating greater interference with daily functioning due to pain. Each of the seven domains is rated on a scale from 0 (no interference) to 10 (complete interference), and the average score across these domains represents the overall pain interference level.
3 months post-op
Pain Interference
Time Frame: 6 months post-op
The Brief Pain Inventory assesses how much a person's pain impacts their daily activities, including general activity, mood, walking, work, relationships with others, enjoyment of life, and sleep, with higher scores indicating greater interference with daily functioning due to pain. Each of the seven domains is rated on a scale from 0 (no interference) to 10 (complete interference), and the average score across these domains represents the overall pain interference level.
6 months post-op
Pain Severity
Time Frame: 1 month post-op
The Brief Pain Inventory (BPI) measures pain severity by asking patients to rate their "worst pain" on a scale from 0 to 10, where a higher score indicates greater pain intensity
