Plain English Summary

Background and study aims
Pregnancy is a stressful life event, and according to Social Readjustment Rating Scale, it has been ranked 12th of the 43 most stressful life events. Pregnancy stress is common and comes from a variety of pregnancy-specific problems, including physical symptoms and changes, changes in body image, medical problems, anxiety about delivery, and concerns about birth and the baby's health. Previous studies have examined the incidence and prevalence of stress levels during pregnancy. The impact of pregnancy stress on women and fetal health can lead to adverse outcomes, including miscarriage, premature labor and birth defects. Maternal psychological stress can also be responsible for any learning and cognitive developmental delays in the child. Many researchers have used cognitive behavioral therapy (CBT) to release stress. Elements of CBT include cognitive restructuring, raising awareness about stress, relaxation training, problem-solving training, self-management and adequate social support. Cognitive behavioral stress management has been applied successfully in many physical and emotional conditions, such as cancer, depression, insomnia and heroin-dependent individuals. However, cognitive behavioral stress management has not yet been fully applied to pregnant women in reducing their pregnancy stress. Thus, this study aims to examine the effects of cognitive behavioral stress management, with cognitive intervention, relaxation techniques, problem-solving training and social support, to reduce pregnancy stress among pregnant women.

Who can participate?
Pregnant women (at early stage of pregnancy, i.e., 6 to 8 weeks of the pregnancy) aged 20-38 years, who are able to come to the hospital for antenatal examinations

What does the study involve?
Participants will be asked to join this study while they came to the hospital obstetric outpatient clinic for antenatal examination. Participants must pass the screening to ensure that they meet the inclusion criteria. Participants will be randomly assigned to either the intervention group and the control group.
The control group receive routine antenatal examination and pregnancy health education instructions (including advice on diet, fetal monitoring and daily care during pregnancy) and the intervention group receive an extra seven cognitive behavior stress management sessions between weeks 8 and 38 of their pregnancy. Participants will be asked to complete a questionnaire at the beginning and end of the study to assess the effectiveness of intervention in terms of reducing pregnancy stress levels.

What are the possible benefits and risks of participating?
The possible benefit of participating is that the intervention may help to reduce pregnancy stress, and the results may enable the improvement of the quality of antenatal care received by women in the future. There are no known risks to participants taking part in this study.

Where is the study run from?
The study is being run by Bengbu Medical College, Anhui, China and takes place in obstetrics of Obstetrics department of the First Affiliated Hospital of Bengbu Medical College, Anhui Prov, China

When is the study starting and how long is it expected to run for?

Scientific title

Effective cognitive behavioural stress management to reduce pregnancy stress among pregnant women: a randomised controlled trial

All pregnant women were required to undergo 7 antenatal visits in accordance with the "Chinese Guidelines for pre-pregnancy and prenatal care" from 12 to 41 weeks of their pregnancy. 100 participants were randomly divided into the control group (N=50) and the intervention group (N=50) using a computerized random number generator.
The control group received routine antenatal care and pregnancy health education instruction (including advice on diet, fetal monitoring and daily care during pregnancy).
Participants in the intervention group underwent an extra 7 cognitive behavioural stress management sessions between weeks 8 and 38 of their pregnancy. The sessions covered information on the physiological and psychological changes in pregnancy, coping methods for pregnancy stress, relaxation techniques, and family support. Following each seminar, the facilitator invited participants to participate in group discussions to share their pregnancy experience, including their problem-solving strategies. The facilitator recorded the process but did not participate the discussion. At the end of the session the facilitator summarized the results of the group discussion and proposed strategies of reducing pregnancy stress to participants. Additionally, individual counseling was provided if the participants required this.The cognitive behavioral stress management was delivered mainly through face-to-face communication in the hospital, but in some cases, it was delivered via phone and e-mail. The whole process for each intervention lasted 40-60 minutes.
