Labor Pain

Brief 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. The rest of participants will be the control group.

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.

Interventions

BEHAVIORALABM affective pain stimuli

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

BEHAVIORALABM sensory pain stimuli

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

BEHAVIORALPlacebo

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