Stress and negative mood during pregnancy increase risk for poor childbirth outcomes and postnatal mood problems and may interfere with mother-infant attachment and child development. However, relatively little research has focused on the efficacy of psychosocial interventions to reduce stress and negative mood during pregnancy. In this study, we developed and pilot tested an eight-week mindfulness-based intervention directed toward reducing stress and improving mood in pregnancy and early postpartum. We then conducted a small randomized trial (n=31) comparing women who received the intervention during the last half of their pregnancy to a wait-list control group. Measures of perceived stress, positive and negative affect, depressed and anxious mood, and affect regulation were collected prior to, immediately following, and three months after the intervention (postpartum). Mothers who received the intervention showed significantly reduced anxiety (effect size, 0.89; p<0.05) and negative affect (effect size, 0.83; p<0.05) during the third trimester in comparison to those who did not receive the intervention. The brief and nonpharmaceutical nature of this intervention makes it a promising candidate for use during pregnancy. This study examined whether a short-term psychosomatic intervention during pregnancy had effects on characteristics of labour and delivery as well as on the long-term course of anxiety, depression and physical complaints in pregnant in-patient women.
                All gynaecological and obstetric inpatients of a university hospital, who had either exhibited complications during their pregnancy or were considered high-risk pregnancies, were examined. Symptoms of anxiety and depression (HADS) and physical symptoms (GBB) were assessed by standardised questionnaires. Women with elevated scores on either the HADS or the GBB were randomly assigned to either a treatment group, which had received a psychosomatic intervention or an untreated control group. Of the n = 238 women who were assessed during their stay in our hospital, n = 135 were included in the follow-up 1-year later.
                More than one-third of the participants (38.7%) had elevated scores of anxiety, depression and/or physical symptoms. The psychosomatic intervention had a significant effect on anxiety scores (p = 0.006), but not on depression scores, physical complaints and characteristics of labour and delivery.
                Findings suggest that a short-term psychosomatic intervention can have a positive long-term effect on anxiety symptoms. Future studies are needed to show whether the reduction of anxiety symptoms in turn can lead to a reduction of postnatal complications and lower rates of disturbed mother-child interactions. Maternal anxiety and stress are found to be predictors of adverse pregnancy outcomes, including low birth weight and prematurity.
                The aim of the study was to determine whether relaxation education in anxious pregnant Iranian women in their first pregnancy affects selected pregnancy outcomes, including birth weight, preterm birth, and surgical delivery rate.
                A total of 110 obstetrically and medically low-risk primigravid women in Iran with a high anxiety level demonstrated by Spielberger's State-Trait Anxiety Inventory were randomly assigned into experimental and control groups.
                In this randomized controlled trial, the experimental group received routine prenatal care along with 7-week applied relaxation training sessions, while the control group received only routine prenatal care. Anxiety and perceived stress were measured by pre-educational and post-educational intervention. Data related to pregnancy outcomes include birth weight, gestational age at birth, and type of delivery.
                Significant reductions in low birth weight, cesarean section, and/or instrumental extraction were found in the experimental group compared with the control group. No significant differences were found in the rate of preterm birth.
                The findings suggest beneficial effects of nurse-led relaxation education sessions during the prenatal period. This intervention could serve as a resource for improving pregnancy outcomes in women with high anxiety. Prior research by the author showed that psychosocial factors distinguished complicated from uncomplicated birth outcome. The purpose of this study was to determine if prenatal hypnosis could facilitate uncomplicated birth. Following a psychosocial assessment, 520 pregnant women in their first or second trimester of pregnancy were randomized to receiving prenatal hypnosis or attention-only groups. The author provided all of the hypnosis in a manner similar to that taught by David Cheek. The goal was to reduce fear of birth and parenthood; to reduce anxiety; to reduce stress; to identify specific fears that might complicate the labor process (addressing them whenever possible); and to prepare women for the experience of labor. The attention-only group was matched to a no-contact comparison group. Women receiving prenatal hypnosis had significantly better outcomes than women who did not. Further assessment suggested that hypnosis worked by preventing negative emotional factors from leading to an complicated birth outcome. Attention only was associated with minimal differences in outcome over the no-contact group. The routine prenatal use of hypnosis could improve obstetric outcome. The majority of randomised controlled trials examining the effectiveness of antenatal group interventions at preventing postnatal depression in "at risk" women have used a "psychoeducational" intervention. The aim of the present study is to evaluate the effectiveness of an antenatal cognitive behavioural group intervention in a primary care setting for pregnant women identified with mild to moderate symptoms in pregnancy and/or at risk of developing depression or anxiety in the perinatal period.
                Subjects were randomised to a CBT group intervention or control condition (information booklet) and administered the EPDS and STAI at pre (Time 1) and post intervention (Time 2), and at 2 months (Time 3) and 4 months postpartum (Time 4). MINIs were administered at Times 1, 3 and 4.
                Of the 774 women approached, 277 accepted and were suitable; thus 191 were randomised to the CBT intervention and 86 to the control condition. The subsequent 52% drop-out left 89 women "completing" the CBT groups and 43 in the control group; these two groups were well matched on demographic variables. Intention to treat analyses revealed relatively low mean baseline EPDS scores (means 6.88 -8.16) with no reduction in EPDS scores in either group from Time 1 to Time 4. MINI depression criteria were fulfilled by 19% of all participants at Time 1 but there was no reduction in depression in either group; in contrast those with MINI anxiety diagnoses reduced from 28% in late pregnancy to 16% at four months postpartum in the CBT group with similar reductions in the control group. Analyses on the 132 "completers" showed significant symptomatic improvement over time for both the CBT group and control condition. Depression scores in the most symptomatic women (EPDS>12; N=19) decreased steadily by over 50% over the total time course but there were no differences in improvement between the CBT and control groups.
                A number of methodological factors may have obscured our results including a tendency to natural remission in mildly symptomatic subjects and the possibility that our control condition was therapeutic in itself.
                While a modest reduction in depression scores was noted in study "completers", both the CBT group intervention control condition were equally beneficial. The reasons for this finding include the low symptom level at baseline; the potential effectiveness of the control condition; and the brevity of the intervention. Women who are traumatized after childbirth find that listening, support, counseling, understanding, and explanation are the most useful treatments. However, little evidence is available from randomized trials of the relative efficacy of these treatments as a positive postnatal intervention. This study purpose was to examine if postnatal "debriefing" by midwives can reduce psychological morbidity after childbirth.
                A randomized trial was conducted in a regional teaching hospital in northwest England. One hundred and twenty postnatal primigravidas were allocated by sealed envelopes to receive the debriefing intervention (n = 56) or not (n = 58). The main outcome measure was the Hospital Anxiety and Depression (HAD) scale administered by postal questionnaire 3 weeks after delivery. The proportion of women in each group with anxiety and depression scores of more than 10 points were compared, using odds ratios and 95% confidence intervals.
                Women who received the intervention were less likely to have high anxiety and depression scores after delivery when compared with the control group.
                The support, counseling, understanding, and explanation given to women by midwives in the postnatal period provides benefits to psychological well-being. Maternity units have a responsibility to develop a service that offers all women the option of attending a session to discuss their labor. Antenatal maternal anxiety has adverse effects on the fetus and the child. In this study we determined whether a short period of directed or of passive relaxation reduced maternal self-rated anxiety, heart rate, plasma catecholamines, cortisol and uterine artery resistance index, in pregnant women.
                Fifty-eight women (28-32 wks gestation) were assigned randomly to a session of directed active or passive (sitting quietly) relaxation. Spielberger self-rating anxiety questionnaires were completed, and a venous blood sample taken, before and after a Doppler scan.
                Both active and passive relaxation significantly reduced State Anxiety and maternal heart rate, but the effect was significantly greater with the active relaxation. In contrast, the passive relaxation significantly reduced noradrenaline levels whereas active did not. Adrenaline levels were not changed significantly with either type of relaxation. Both methods significantly reduced cortisol, with a trend for the passive to have a greater effect. The active relaxation had no effect on uterine artery blood flow, whereas there was a statistically significant, but clinically negligible, increase in mean resistance index after passive relaxation.
                Both methods reduced maternal State Anxiety and heart rate, the active method more so. However there was a striking lack of correlation with the other biological indices studied. In order to reduce specific biological effects of anxiety during pregnancy, different methods may be needed from those which are most effective at reducing subjective anxiety. To test the effectiveness of an efficacy-enhancing educational intervention to promote women's self-efficacy for childbirth and coping ability in reducing anxiety and pain during labour.
                The evidence of the effective application of the self-efficacy theory in health-promoting interventions has been well established. Little effort has been made by health professionals to integrate self-efficacy theory into childbirth care.
                Randomised controlled trial.
                An efficacy-enhancing educational intervention based on Bandura's self-efficacy theory was evaluated. The eligible Chinese first-time pregnant women were randomly assigned to either an experimental group (n = 60) or a control group (n = 73). The experimental group received two 90-minute sessions of the educational programme in between the 33rd-35th weeks of pregnancy. Follow-up assessments on outcome measures were conducted within 48 hours after delivery. The short form of the Chinese Childbirth Self-Efficacy Inventory was used to measure maternal self-efficacy prior to labour. Evaluation of pain and anxiety during the three stages of labour and performance of coping behaviour during labour were measured by the Visual Analogue Scale and Childbirth Coping Behaviour Scale respectively.
                The experimental group was significantly more likely than the control group to demonstrate higher levels of self-efficacy for childbirth (p < 0.0001), lower perceived anxiety (p < 0.001, early stage and p = 0.02, middle stage) and pain (p < 0.01, early stage and p = 0.01, middle stage) and greater performance of coping behaviour during labour (p < 0.01).
                The educational intervention based on Bandura's self-efficacy theory is effective in promoting pregnant women's self-efficacy for childbirth and reducing their perceived pain and anxiety in the first two stages of labour.
                Relief of pain and anxiety is an important issue for both women and childbirth health professionals. The efficacy-enhancing educational intervention should be further developed and integrated into childbirth educational interventions for promoting women's coping ability during childbirth. Eighty-four depressed pregnant women were recruited during the second trimester of pregnancy and randomly assigned to a massage therapy group, a progressive muscle relaxation group or a control group that received standard prenatal care alone. These groups were compared to each other and to a non-depressed group at the end of pregnancy. The massage therapy group participants received two 20 min therapy sessions by their significant others each week for 16 weeks of pregnancy, starting during the second trimester. The relaxation group provided themselves with progressive muscle relaxation sessions on the same time schedule. Immediately after the massage therapy sessions on the first and last days of the 16-week period the women reported lower levels of anxiety and depressed mood and less leg and back pain. By the end of the study the massage group had higher dopamine and serotonin levels and lower levels of cortisol and norepinephrine. These changes may have contributed to the reduced fetal activity and the better neonatal outcome for the massage group (i.e. lesser incidence of prematurity and low birthweight), as well as their better performance on the Brazelton Neonatal Behavior Assessment. The data suggest that depressed pregnant women and their offspring can benefit from massage therapy.
Mind-body interventions might benefit women’s anxiety during pregnancy. Based on individual studies, there is some but no strong evidence for the effectiveness of mind-body interventions for the management of anxiety during pregnancy. The main limitations of the studies were the lack of blinding and insufficient details on the methods used for randomization.
