Trial summary

The primary objective of this study is to examine the effects of Attentional Bias Modification (ABM) on the labor pain in parturients. One-third of the participants will undergo ABM training away from affective pain stimuli. One-third of the participants will undergo ABM training away from sensory pain stimuli.

About this study

The primary objective of this study is to examine the effects of Attentional Bias Modification (ABM) on the labor pain in parturients. One-third of the participants will undergo ABM training away from affective pain stimuli. One-third of the participants will undergo ABM training away from sensory pain stimuli. The rest of participants will be the control group.

Read the detailed description

In recent years, significant attention has been paid to the attentional bias in patients with chronic pain. Studies found that Attentional Bias Modification (ABM) could reduce the pain intensity in participants with chronic pain. The investigator's goal is to evaluate the effects of ABM on labor pain and patient satisfaction with the labor and delivery experience.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ABM affective pain stimuliBehavioural

    Patients undergo ABM training to shift attention away from affective pain stimuli

  • ABM sensory pain stimuliBehavioural

    Patients undergo ABM training to shift attention away from sensory pain stimuli

  • PlaceboBehavioural

    Patients undergo ABM training to receive affective/neutral and sensory/neutral word pairs

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Effects of Attentional Bias Modification (ABM) on labor pain

    Change in pain threshold and labor pain as measured by Fear of Pain Questionnaire (FPQ), Brief Pain Inventory (BPI) and McGill Pain Questionnaire (MPQ) before and after the ABM training.

    Measured: 4 weeks (starting from 36-week gestation)

Questions about this trial

What is this clinical trial studying?

A study testing ABM affective pain stimuli and ABM sensory pain stimuli in people with Labor Pain, run by Harvard Medical School (HMS and HSDM).

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 4 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: withdrawn, as of the sponsor's last update on 13 May 2024. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 was withdrawn before enrolling participants, so there are no results.

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?

Effects of Attentional Bias Modification (ABM) on labor pain (time frame: 4 weeks (starting from 36-week gestation)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04662450, which also lists 3 linked publications.

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 13 May 2024.
