Compararing the Impact of Face-to-Face and Online Peer Education on Pregnant Women’s Fear of Childbirth: A Randomized Clinical Trial

Introduction

Pregnancy is a memorable experience and at the same time the most critical period in women’s lives, and can also be one of the most stressful situations for them. Women's mental health during pregnancy is important for the well-being of the mother and child (1). Pregnant women express constant concerns about the health of the fetus, child care, lifestyle changes, and fear of labor pain (2). Fear of childbirth (FOC) is a prevalent condition that impacts the outcome of pregnancy (3). The prevalence of FOC in Scandinavian countries, England, Australia, and Sweden is reported to be 22% (4), and in Iran, it is prevalent in 5-20% of pregnant women. In other words, every 1 out of 5 women is afraid of giving birth (5).

 The Fear of labor pain and the mother’s attitude of her inability to tolerate the labor and childbirth process are the reasons for increasing cesarean sections without indications (6). A lot of fear during pregnancy may be accompanied by decreased uterine contractions and prolonged and obstructed labor, irregular fetal heart rate patterns, low Apgar score, increased perinatal death, and low birth weight neonates (7,8). Moreover, blood flow to the pelvic muscles is restricted and oxygenation is reduced in response to an increase in catecholamines and serum cortisol due to fear that can lead to increased pain in the mother (9,10). FOC is associated with depression, anxiety, and nutritional disorders (8). Fear of labor pain, fear of death, fear of unknown problems, low childbirth self-efficacy, concerns about postpartum sexual health, newborn health concerns (11), and unawareness (12) are some of the factors that contribute to FOC.

Considering that primiparous women are more afraid of giving birth training these mothers can improve their mental health (13). Education can be applied by a group of peers who have experienced similar situations in life (14). A peer is a person who is similar to another person in terms of some characteristics such as age, gender, occupation, socio-economic status, or health status. Peer education is a process whereby well-trained and motivated young individuals engage in organized or informal education with their peers. Peer education causes to share knowledge and experience among people thus addressing their health needs. They take responsibility for their peers. This process aims to develop people's awareness, attitudes, beliefs, and skills and empower them to accept responsibility and protect their health (15). Peer support means the use of individual support with experiential knowledge used and managed in the best way to support people in a similar situation (16). Peer education can be provided in different ways, including group support, individual support, and offline communication such as telephone and the Internet. The World Health Organization has described mobile health (mHealth) as the use of mobile and wireless communication technologies in providing health services to improve healthcare delivery, outcomes, and research (17).

The heavy burden of responsibility for care, lack of human resources in healthcare centers, limited financial resources to support the healthcare infrastructure and the development of education, and the rapid growth of mobile phone penetration among nations, and low-income countries are the reasons for turning to the use of mobile phones in the field of health (18). Several studies have addressed peer support using mobile phones to reduce depression (19), breast cancer problems (20), and diabetes (21). In addition, studies have confirmed the positive effect of peer education on reducing FOC (22) and increasing the intention to have a natural birth (23).

In Iran, the rate of cesarean section is high due to FOC (6), yet there is an urgent need for low-cost, and simple training interventions to reduce FOC in women. To this end, this study aimed to compare two types of educational approaches including face-to-face and online peer education in reducing FOC in pregnant women referring to comprehensive health centers in Meshgin Shahr, Ardabil Province, Iran.

Materials and Methods

This three-armed clinical trial was conducted from June 2020 to December 2020 on 66 pregnant women referring to community health centers in Meshgin Shahr, Ardabil Province, Iran. The study was registered in Iranian Registry of Clinical Trials (IRCT) under code of IRCT20200404046943N1.

Following the rsults of the study by Ghazaie et al. (24), the population size was calculated as 66 people (22 people in each group) using the following formula, considering a 30% dropout probability. The mean and standard deviation for the two intervention groups (S1=7.12 and X1=85.64) and the control group (S2=10.21 and X2=97.41) were calculated at a 99% confidence interval and a 95% test power. 

The inclusion criteria consisted of living in Meshgin Shahr, being primigravida, age range of 18-35 years, having a low-risk pregnancy, the gestational age of 24-32 weeks, obtaining an FOC score of less than 85 before entering the study, having a smart cell phone, having the possibility of installing the WhatsApp messenger and the ability to use it (for the participants in the intervention group), having the willingness for participation in the study, having Persian reading and writing skills, absence of physical and mental illness, and not having indicators for a cesarean section as indicated in the mothers’ electronic medical records. The exclusion criteria were the absence or irregular attendance in the training classes, the detection of any pregnancy complications (e.g., preeclampsia, bleeding, diabetes, intrauterine fetal death, and preterm delivery), and a history of physical trauma. Moreover, at every stage, a mother who does not want to continue participating in the study were free to leave the study.

The participants in this study were selected through multi-stage sampling. To do so, Meshgin Shahr was divided into three districts in terms of social, economic, and cultural conditions. Then, two comprehensive health centers were randomly selected from each cluster. In the next step, 66 pregnant women who met the inclusion criteria were selected from the selected healthcare centers through convenience sampling. The selected women were assigned to the three groups using permuted blocks with all possible combinations of AABBCC blocks. Moreover, a code was assigned to each candidate, and then 11 codes were randomly selected. The codes were blinded to ensure no bias. It should be noted that all the mothers in the three groups received routine prenatal training, such as getting ready for labor, birth, breastfeeding, and caring for the newborn. Six people were excluded from the study for various reasons (Figure 1).

 The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) is a 33-item self-reported scale, widely known for measuring childbirth fear, and was developed by Wijma et al. (1998). Items are scored on a six-point Likert scale (from ‘never’ =0 to ‘very often’ =5). Total scores vary from 0 to 165, with higher scores suggesting a greater level of FoC.  Items 2, 3, 6, 7, 8, 11, 12, 15, 19, 20, 24, 25, 27, and 31 are scored in reverse. The reliability of this questionnaire in a study done by Wijma and colleagues with a Cronbach’s alpha of 0.93(25).  In study by Mortazavi`, the reliability of W-DEQ (A) was confirmed with a Cronbach’s alpha of 0.91  for nulliparous and multiparous women (26).

The objectives of the study and the research protocols were explained to the selected participants, and written informed consent was then obtained from them. Moreover, the questionnaires were completed for them through the self-report method. The participants in the face-to-face peer education group attended five training sessions once a week in groups of 5 to 6 people. The training content (Table 1) was developed based on the recommendations of the World Health Organization to reduce the rate of cesarean delivery (27).

Each session lasted 90 minutes. The same training content was provided to the participants in the online peer education group via WhatsApp messenger in 4 groups of 5-6 people through group chats, audio files, and educational videos (from various websites), questions and answers with group members, and discussing the training provided by peers. The researcher was the admin and supervisor in the online training sessions. Each group consisted of 5-6 members and one peer. The group members could raise any questions and opinions in the group until the next session, and the peers would answer their questions under the supervision of the researcher. Before and 4 weeks after the last sessions, the items in Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) were completed for all participants in the three groups. Educational content was presented to the members of the control group in the form of pamphlets and CDs after completing the study. Inclusion criteria for peers included: consent to participate in the study, Iranians and residents of Meshgin Shahr, having at least a high school diploma, a history of vaginal birth, and participation in preparation courses for physiological childbirth. The exclusion criteria for the peer volunteers were the absence of more than one training session and the refusal to continue participating in the study. The researcher held a 15-hour training workshop (5 sessions of 3 hours) for candidates separately in each center. Before and after the workshop, the pre-test and post-test were conducted for all volunteers. In the end, 16 candidates who completed the training course and obtained 75% of the post-test scores were selected as peers. The data in the present study were collected using a demographic questionnaire and the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) – Version A (25). The demographic survey includes questions on age, education, occupation, and household income. In the present study, the validity of the questionnaires was determined using the content and face validity methods.

Collected data were analyzed using SPSS version 16.0. First, the Kolmogorov–Smirnov test was used to determine the normal distribution of the data. Analysis of variance (ANOVA) was employed to determine the differences between the three groups in terms of FOC mean score. The paired-Samples t-test was used to assess the mean differences between pre-and post-test scores. The significance level was set at P<0.05.

Results

Kolmogorov–Smirnov test, and finally, demographic data were matched in 3 groups (Table 2). The mean age of pregnant women was 24.03±3.6 years and the mean of gestational age was 26.05±1.43 weeks.

There was no significant difference between the FOC scores in the three groups at baseline measurement (P = 0.101), but a significant difference was observed in FOC scores among the three groups (P = 0.001) after one month of intervention (Table 3).  

Further, the Post Hoc test showed a significant difference between the group receiving face-to-face peer education and the control group (P < 0.001) as well as, the online peer education with the control group (P < 0.001). A significant difference was found between the face-to-face peer education and online peer education groups (P = 0.000) (Table 4).

Discussion

This study examined the effect of face-to-face and online training interventions by peers compared with the control group. The findings showed that at the end of the intervention, the FOC scores in both face-to-face and online peer education groups had a significant decrease compared to their pre-intervention scores and the scores obtained by the control group. One month after the completion of the intervention, the two face-to-face and online peer education groups showed a greater decrease in the fear of childbirth score compared to their pre-intervention scores and the scores obtained by the control group.

In line with our results, Rahmani et al. (2020) showed that peer education was more effective in reducing the fear of childbirth in pregnant women compared to the discussion group by healthcare workers (22). Moreover, Alidoost et al. (2014) showed that the intervention by peers increased women’s motivation for natural childbirth and decreased the intention of cesarean section (23).

One of the main reasons for fear of childbirth is incomplete or misleading information(28). The Harsanyi Doctrine states that the difference in the level of knowledge causes different levels of beliefs and attitudes in people (29). Thus, providing psychological training in line with cognitive-behavioral therapy to reduce the causes of fear of childbirth, and anxiety and assess the benefits and harms of natural childbirth and cesarean delivery, leads to the development of the necessary knowledge and skills in expectant mothers and, as a result, reduces their fear.  In line with the present study, most of the studies have shown positive and useful benefits of the peer-centered education approach. The desirable outcomes of this method can be attributed to the fact that peers share their experiences in simple terms and pregnant women are more probably to trust the experiences of those who have already been in similar situations. In the peer education approach, people protect their health and develop their level of knowledge, attitudes, and skills. In this process, the peer and members of a group strengthen the sense of empathy that leads to increased knowledge.

Godarzi et al. (2015) showed that breastfeeding education through peer support increased mothers' perceived ability to breastfeed their new infant (30). Molazem et al. (2018) also concluded that peer education effectively reduced fear and anxiety in patients undergoing coronary angiography (31). Another study showed that patients who have received peer education had higher self-efficacy compared to those who received nursing education (32).

However, Tafazzoli et al. (2013) reported that peer support and education by healthcare workers during pregnancy do not affect the initiation of breastfeeding (33). The inconsistency in these studies can be related to the difference in social values and culture, personality conditions, and different aspects of the birth experience of women. The quality of peer education can play a significant role in learning outcomes. Criteria such as listening, self-confidence, the ability to communicate clearly with peers, and the ability to stimulate and encourage peers should be taken into consideration when choosing peer coaches. The differences in peer education outcomes in different studies can be attributed to various factors such as peer selection, failure to encourage and motivate peers to participate in the selected discussions, and improper group control. Several studies have shown that peer support using mobile phones has been effective in reducing distress and problems of women with breast cancer (34) and self-care in patients with diabetes (35).

Nieminen et al. (2016) assessed the feasibility of CBT-based internet interventions in primigravid women with extreme fear of childbirth. The results showed that primiparous women who had a severe fear of childbirth could be treated using a CBT-based self-help program through the internet (36).

Considering the effectiveness of education through mobile phones, it can be said that mobile phones act as a guide for action (positive signs that people receive from their surroundings and internal environment) and act as a reminder and encourage people to change and improve their attitudes. It seems that the availability of mobile phones and the information and reminders provided by them can reduce worry and fear, confirming the benefits of new technologies, especially mobile phones in health education. Mobile phones are available to almost everyone and can be used to overcome many obstacles, including the problem of access to different social groups, lack of financial resources, and lack of physical space, especially in critical situations such as the COVID-19 pandemic.

The main limitation of this study was the selection of only the women who could access and use a smart cell phone and the WhatsApp messenger. One important strength of our study was its randomised, controlled design. Besides, the study was performed with primiparous women to understand the effect of peer education clearly. This is the first study, to our knowledge to investigate the effects of face-to-face and online peer education.

Conclusion

Face-to-face and online peer education are effective in reducing the FOC in pregnant women. Peer education methods are a complementary supplement to mental health promotion. Such methods can be used for developing national health policies and planning for encouraging women to natural childbirth and as a consequence reduction of cesarean section.
