The efficacy of cognitive behavior therapy for the treatment of perinatal anxiety symptoms: A preliminary meta-analysis

Exposure-based cognitive-behaviour therapy for anxiety-related disorders in pregnancy (ADEPT): Results of a feasibility randomised controlled trial of time-intensive versus weekly CBT

BACKGROUND

Exposure-based cognitive-behaviour therapies (CBT) are effective but their acceptability in pregnancy is untested. Time-intensive delivery of CBT (INT-CBT) may accelerate treatment response. This feasibility trial aimed to explore this.

METHODS

This multi-centre parallel-group trial recruited pregnant women with anxiety-related disorders via maternity and mental health settings and randomised (1:1) to INT-CBT (8-10 treatment hours over two weeks) or standard weekly one-hour CBT sessions (WCBT). Both groups also received late pregnancy and postpartum follow-ups. Participants received 10-12 total hours of individual therapy using remote delivery (95 %). Outcomes were assessed: at baseline; after two weeks of treatment, late pregnancy, at 1 and 3 months postpartum (by blinded assessors), alongside a qualitative interview. Pre-specified primary feasibility outcomes regarding acceptability, recruitment and retention were evaluated. The secondary outcome of adjusted mean difference was estimated for the proposed primary outcome.

RESULTS

All feasibility outcomes were met. Of 135 screened, 59 women were randomised into the trial (29 INT-CBT:30 WCBT). 93 % completed treatment and 81 % provided data at 3 m postpartum. No adverse effects were attributable to treatment. Women receiving INT-CBT showed a reduction in anxiety (GAD-7) after two weeks of treatment compared to WCBT (aMD = -4.17, 95%CI -6.03 to -2.31) with narrower difference at 3-month postpartum aMD = -0.11 (95%CI -3.23, 3.00). Women described the momentum of INT-CBT as helpful to drive change.

CONCLUSIONS

Exposure-based therapies are acceptable to pregnant women. INT-CBT may reduce anxiety quickly and should be tested in a confirmatory trial examining longer term outcomes. There may be limitations to generalisability from sampling and COVID.

Patient and therapist experiences of exposure therapy for anxiety-related disorders in pregnancy: qualitative analysis of a feasibility trial of intensive versus weekly CBT

BACKGROUND

Approximately 15% of pregnant women experience anxiety disorders. Effective treatments exist but their acceptability during pregnancy, particularly exposure therapy, is not known.

AIMS

To understand patient and therapist experiences of time-intensive and weekly exposure-based therapy for anxiety disorders delivered during pregnancy. Trial registration: ISRCTN81203286.

METHOD

In-depth interviews were conducted with patients and therapists who had taken part in a feasibility trial of predominantly online time-intensive versus weekly cognitive-behavioural therapy in pregnancy in a primary care setting in the UK. Data were analysed using reflexive thematic analysis.

RESULTS

In total, 45 women participating in the trial and 6 therapists who had delivered the treatments were interviewed. Five themes were developed from the data that showed convergence from therapist and patient perspectives: 'Acquiring tools to navigate the perinatal period'; 'Motivated yet constrained by pregnancy'; 'Having the confidence to face fears and tolerate uncertainty'; 'Momentum with the need for flexibility'; 'Being removed from the face-to-face world'.

CONCLUSIONS

Exposure therapy is acceptable and helpful in pregnancy and can lead to lasting gains. Exposure is a key element of treatment and needs to be confidently conducted by therapists with perinatal knowledge and expertise. Treatments need to consider the unfolding context of pregnancy. The momentum of intensive therapy can lead to rapid improvements, but is demanding for both patients and therapists, especially fitting round other commitments. Online treatments can work well and are a good fit for perinatal women, but this needs to be balanced with the need for social connection, suggesting a hybrid model is the ideal.

Can psychological interventions prevent or reduce risk for perinatal anxiety disorders? A systematic review and meta-analysis

OBJECTIVE

Little is known about the extent to which interventions can prevent perinatal anxiety disorders. We conducted a systematic review and meta-analysis to examine whether interventions can decrease the onset and symptoms of perinatal anxiety among individuals without an anxiety disorder diagnosis.

METHOD

We conducted a comprehensive literature search across five databases related to key concepts: (1) anxiety disorders/anxiety symptom severity (2) perinatal (3) interventions (4) prevention. We included studies that examined a perinatal population without an anxiety disorder diagnosis, included a comparator group, and assessed perinatal anxiety. We included interventions focused on perinatal anxiety as well as interventions to prevent perinatal depression or influence related outcomes (e.g., physical activity).

RESULTS

Thirty-six studies were included. No study assessing the incidence of perinatal anxiety disorder (n = 4) found a significant effect of an intervention. Among studies assessing anxiety symptom severity and included in the quantitative analysis (n = 30), a meta-analysis suggested a small standardized mean difference of -0.31 (95% CI [-0.46, -0.16], p < .001) for anxiety at post intervention, favoring the intervention group. Both mindfulness (n = 6), and cognitive behavioral therapy approaches (n = 10) were effective.

CONCLUSIONS

Interventions developed for perinatal anxiety were more effective than interventions to prevent perinatal depression. Psychological interventions show promise for reducing perinatal anxiety symptom severity, though interventions specifically targeting anxiety are needed.

Non-pharmacological interventions for the management of perinatal anxiety in primary care: a meta-review of systematic reviews

BACKGROUND

Perinatal anxiety (PNA), anxiety that occurs during pregnancy and/or up to 12 months postpartum, is estimated to affect up to 21% of women, and may impact negatively on mothers, children, and their families. The National Institute for Health and Care Excellence (NICE) has called for further research around non-pharmacological interventions in primary care for PNA.

AIM

To summarise the available international evidence on non-pharmacological interventions for women with PNA in a primary care population.

DESIGN & SETTING

A meta-review of systematic reviews (SRs) with narrative synthesis was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidance.

METHOD

Systematic literature searches were conducted in 11 health-related databases up to June 2022. Titles, abstracts, and full-text articles were dual-screened against pre-defined eligibility criteria. A variety of study designs were included. Data were extracted about study participants, intervention design, and context. Quality appraisal was performed using the AMSTAR 2 tool (A MeaSurement Tool to Assess systematic Reviews). A patient and public involvement group informed and contributed towards this meta-review.

RESULTS

Twenty-four SRs were included in the meta-review. Interventions were grouped into the following six categories for analysis purposes: psychological therapies; mind-body activities; emotional support from healthcare professionals (HCPs); peer support; educational activities; and alternative or complementary therapies.

CONCLUSION

In addition to pharmacological and psychological therapies, this meta-review has demonstrated that there are many more options available for women to choose from that might be effective to manage their PNA. Evidence gaps are present in several intervention categories. Primary care clinicians and commissioners should endeavour to provide patients with a choice of these management options, promoting individual choice and patient-centred care.

The effectiveness of psychological interventions for anxiety in the perinatal period: A systematic review and meta-analysis

PURPOSE

Anxiety disorders are relatively common during pregnancy and the postnatal period. Despite their potential acceptability to users, psychological interventions research for this population is still in its infancy. The meta-analysis aimed to comprehensively evaluate the evidence of the effectiveness of psychological interventions for reducing perinatal anxiety.

METHOD

The review followed PRISMA guidelines. A total of 26 studies published between 2004 and 2022 fulfilled inclusion criteria of which 22 were included in the meta-analysis.

RESULTS

Results indicated that psychological interventions were more effective than control conditions in reducing symptoms of perinatal anxiety (equivalent to a medium post treatment effect size). Effect sizes were robust for cognitive, behavioural and mindfulness-based interventions. Targeting anxiety also appeared to impact on depression symptoms. There was substantial evidence of methodological heterogeneity.

CONCLUSIONS

This review demonstrates that psychological interventions are effective in reducing symptoms of both anxiety and comorbid anxiety and depression in both the antenatal and postnatal periods. Further research on longer-term effects, infant outcomes, treatment approach and modality are required.

Effects of maternal stress and/or anxiety interventions in the first 1000 days:Systematic review of reviews

OBJECTIVE

Effective interventions are needed to mitigate effects of stress and anxiety from conception and up to two years postpartum (the first 1000 days), but it is unclear what works, for what populations and at what time points. This review aimed to synthesise evidence from existing reviews of the effects of stress and anxiety interventions.

METHODS

A systematic review of systematic reviews was conducted. PsycINFO, CINAHL, MEDLINE and the Cochrane databases were searched (inception to January 2020). Reviews were eligible if they examined effects of interventions during the first 1000 days on women's stress and/or anxiety. Extracted data were narratively synthesised. Review quality was assessed using existing recommendations including the AMSTAR tool .

RESULTS

Thirty-four reviews were eligible for inclusion; 21 demonstrated high methodological quality. Cognitive behavioural therapy demonstrates some beneficial effects for anxiety across the first 1000 days for general and at-risk populations. Support-based interventions demonstrate effects for stress and anxiety for at-risk mothers in the postpartum. Music, yoga and relaxation demonstrate some effects for stress and anxiety, but studies are limited by high risk of bias.

CONCLUSION

Existing evidence is inconsistent. Cognitive behavioural therapy and support-based interventions demonstrate some benefits. Further methodologically and conceptually robust research is needed.

In-person 1-day cognitive behavioral therapy-based workshops for postpartum depression: a randomized controlled trial

BACKGROUND

Postpartum depression (PPD) affects up to one in five mothers and birthing parents, yet as few as 10% access evidence-based treatment. One-day cognitive behavioral therapy (CBT)-based workshops for PPD have the potential to reach large numbers of sufferers and be integrated into stepped models of care.

METHODS

This randomized controlled trial of 461 mothers and birthing parents in Ontario, Canada with Edinburgh Postnatal Depression Scale (EPDS) scores ⩾10, age ⩾18 years, and an infant <12 months of age compared the effects of a 1-day CBT-based workshop plus treatment as usual (TAU; i.e. care from any provider(s) they wished) to TAU alone at 12-weeks post-intervention on PPD, anxiety, the mother-infant relationship, offspring behavior, health-related quality of life, and cost-effectiveness. Data were collected via REDCap.

RESULTS

Workshops led to meaningful reductions in EPDS scores (m = 15.77 to 11.22; b = -4.6, p < 0.01) and were associated with three times higher odds of a clinically significant decrease in PPD [odds ratio (OR) 3.00, 95% confidence interval (CI) 1.93-4.67]. Anxiety also decreased and participants had three times the odds of clinically significant improvement (OR 3.20, 95% CI 2.03-5.04). Participants reported improvements in mother-infant bonding, infant-focused rejection and anger, and effortful control in their toddlers. The workshop plus TAU achieved similar quality-adjusted life-years at lower costs than TAU alone.

CONCLUSIONS

One-day CBT-based workshops for PPD can lead to improvements in depression, anxiety, and the mother-infant relationship and are cost-saving. This intervention could represent a perinatal-specific option that can treat larger numbers of individuals and be integrated into stepped care approaches at reasonable cost.

The impact of telemental health interventions on maternal mental health outcomes: a pilot randomized controlled trial during the COVID-19 pandemic

Background

The lethal potential of COVID-19 was often emphasized and repeatedly brought to the attention of pregnant women, leading to a higher level of anxiety, depression, and COVID-19-specific phobia among this population. Furthermore, legislation forced social distancing and isolation to interrupt the infection cycle. Together these factors resulted in higher maternal mental health distress requiring intervention. Nevertheless, there is a lack of evidence regarding the impact of low-intensity psychosocial telemental interventions on maternal mental health outcomes. Therefore, the objective of this pilot study is to assess the efficacy of video low-intensity psychosocial telemental maternal intervention on COVID-19-specific phobia, antenatal depression, and anxiety among pregnant women. We hypothesized that the intervention arm would be superior to the control arm. A parallel design randomized interventional controlled trial with 1:1 randomization was conducted at the Women Wellness and Research Center. We enrolled fifty-eight pregnant women in their second trimester who spoke English or Arabic. We assessed antenatal anxiety, depression, and Covid-19-specific phobia at baseline (T₀), and thirty-three pregnant women completed the follow-up after four weeks (T₁). Pregnant women receiving psychotropic medications and follow up in mental health services were excluded.

Results

A low-intensity psychosocial telemental maternal session helps reduce antenatal anxiety. We found statistically significant differences in antenatal anxiety scores between the intervention (2.4 ± 2.2) and control (4.2 ± 1.6) groups (p = 0.013) with a large effect size of Hedges' g value (0.96, 0.22-1.74). The absolute risk reduction was 27.27 percent. However, the intervention had no statistically significant effect on reducing antenatal depression or COVID-19-specific phobia.

Conclusions

Low-intensity psychosocial telemental maternal sessions effectively reduce antenatal anxiety. While our findings are promising, further RCTs are needed to replicate these findings.

RAPID-2 study protocol: a cluster randomised feasibility trial of a midwife facilitated intervention for pregnant women with symptoms of mild to moderate anxiety

INTRODUCTION

Many women experience symptoms during pregnancy. Elevated and prolonged anxiety can have negative effects on the woman and baby. The RAPID intervention aims to provide suitable, timely support for women with mild-moderate anxiety. The RAPID intervention is based on social support, relational continuity, psychological and relaxation response theory, and comprises midwife facilitated group discussions, one-to-one support and directed self-help materials.

METHODS AND ANALYSIS

Four National Health Service Trusts in England that provide maternity care will be cluster randomised to the RAPID intervention plus usual care or usual care. At each intervention site, two midwives and two maternity support workers will facilitate the intervention over a 12-week period. Eligibility includes nulliparous women at 16-20 weeks of pregnancy (n=50) with self-report symptoms of mild-moderate anxiety. Community midwives will signpost women to the study. The aim of the study is to establish the feasibility of conducting a definitive trial to examine the effectiveness of the RAPID intervention in addition to usual care. The objectives are to assess recruitment and completion rates, and a qualitative assessment of women's and facilitators' experiences of participation. An estimation of change in the seven-item Generalised Anxiety Disorder scale will inform the sample size for a definitive cluster trial.

ETHICS AND DISSEMINATION

Ethical approval was given by East Midlands-Derby Research Ethics Committee 14 March 2022 (REC Reference: 22/EM/0018). Findings will be made available through publication in peer-reviewed journals, conferences and to participants. A final report will be submitted to HEE/NIHR ICA awards committee for publication.

The Efficacy of Digital Cognitive–Behavioral Interventions in Supporting the Psychological Adjustment and Sleep Quality of Pregnant Women with Sub-Clinical Symptoms: A Systematic Review and Meta-Analysis

The present meta-analysis investigated the overall and differential efficacy of digital cognitive–behavioral therapies (CBTs) vs. third-generation CBTs deployed to pregnant women in reducing sub-clinical depression, anxiety, and stress symptoms while fostering sleep quality and quality of life. A PRISMA-guided systematic search was used, including randomized controlled trials (RCTs) evaluating the above-mentioned interventions. Data were pooled using either the mean difference (MD) or standardized MD (SMD). Sub-group analyses were carried out when appropriate. The primary outcomes were depression, anxiety, and stress symptoms, as well as sleep quality and quality of life. The interventions’ acceptability was evaluated through the odds ratio (OR) of drop-out rates. Seven RCTs were included, comprising 1873 pregnant women. The results showed the interventions’ efficacy in terms of reducing depression symptoms (SMD = −0.36, CI = 0.61, −0.11, k = 9) at the endpoint, although it was not maintained at follow-up during the postpartum period. The interventions’ efficacy in terms of reducing anxiety symptoms (SMD = 1.96, CI = −2.72, −1.21, k = 3) at the endpoint was also significant, while having no effect on sleep quality. The interventions were well accepted (OR = 1.68; 95% CI = 0.84, 3.35; k = 7). Although no sound conclusions can be drawn concerning the joint or differential efficacy of the considered interventions, this study was useful in highlighting the need to develop evidence-based digital prevention programs for pregnant women with sub-clinical symptoms.

Intolerance of Uncertainty and Perfectionistic Beliefs About Parenting as Cognitive Mechanisms of Symptom Change During Cognitive Behavior Therapy for Perinatal Anxiety

OBJECTIVE

A recent randomized controlled trial of group cognitive behavior therapy (CBGT) for perinatal anxiety showed that CBGT is effective in reducing anxiety and depression in pregnant and postpartum women. In secondary analyses, the role of potential mechanisms of symptom change was examined, including intolerance of uncertainty (IU), self-oriented parenting perfectionism (SOPP) and societal-prescribed parenting perfectionism (SPPP).

METHOD

The sample included 75 women (M_age = 31.99, SD = 3.57; 37.3% pregnant, 62.7% postpartum) who sought treatment for anxiety and completed the 6-week CBGT or 6-week waitlist within the larger trial. Measures of anxiety (State-Trait Inventory for Cognitive and Somatic Anxiety; STICSA), depression (Edinburgh Postnatal Depression Scale; EPDS), and the proposed mediators (IU, SOPP, SPPP) were completed at baseline and 6-weeks post-baseline.

RESULTS

Two moderated mediation models were evaluated to identify potential mediators of the effect of condition (CBGT, waitlist) on anxiety (STICSA; Model 1) or depressive symptoms (EPDS; Model 2). In Model 1, changes in IU partially mediated the effect of condition on anxiety (STICSA) for both pregnant and postpartum women. Changes in SOPP and SPPP were partial mediators for postpartum women only. Change in depression (EPDS) was also a partial mediator for pregnant women in this model. In Model 2, none of the cognitive variables mediated the effect of condition on depressive symptoms (EPDS). However, change in anxiety (STICSA) was a significant mediator of the effect of condition on depression (EPDS) and only among pregnant women.

CONCLUSIONS

The results provide support for IU, SOPP and SPPP as mechanisms of change during CBGT and identify differences in important mechanisms among pregnant and postpartum women.

Effect of short-term psychological intervention on anxiety of pregnant women with positive screening results for chromosomal disorders: a randomized controlled trial

Background and aim

Prenatal diagnosis of fetal abnormalities is a critical and stressful event for women. Most pregnant women are concerned about fetal abnormalities and screening tests. Due to the importance of anxiety reduction in pregnant women, this study was conducted to determine the effect of short-term psychological intervention on the anxiety of pregnant women with positive screening results for chromosomal disorders.

Methods

A randomized clinical trial was performed on women referred to Akbarabadi Hospital in Tehran, Iran, who had positive screening results for chromosomal abnormalities. Participants were selected from eligible individuals by a continuous method and were assigned to two groups of cognitive-behavioral training (n = 46) and control (n = 46), using the block balanced randomization method. Participants in the cognitive-behavioral training group received 4 sessions of individual counseling. The control group received routine pregnancy visits. The Spielberger State-Trait Anxiety Inventory was completed before the intervention and immediately at the end of the intervention (before receiving the amniocentesis result). The analysis of intervention effects was performed as intention-to-treat and per-protocol analysis.

Results

There was a statistically significant difference in post-intervention state anxiety scores and trait anxiety scores (p <  0.001) between the intervention and control groups, when their means were adjusted for pre-intervention scores for both intention-to-treat and per-protocol analysis. Also, there was a large effect size between the groups in terms of state (ITT: η_p² = 0.63, PP: η_p² = 0.71) and trait (ITT: η_p² = 0.72, PP: η_p² = 0.75) anxiety scores clinically for both intention-to-treat and per-protocol analysis. The intervention group had a statistically significant and large decrease in state and trait anxiety scores from pretrial to post-trial. In contrast, the control group had a statistically significant and medium increase in state and trait anxiety scores from pretrial to post-trial.

Conclusion

The results showed that cognitive-behavioral training reduced the anxiety of pregnant women with positive screening results for chromosomal disorders. According to the results, it is recommended to hold cognitive-behavioral training classes to reduce the anxiety of pregnant women with a positive screening result for chromosomal disorders.

Effect of Online 1-Day Cognitive Behavioral Therapy-Based Workshops Plus Usual Care vs Usual Care Alone for Postpartum Depression: A Randomized Clinical Trial

IMPORTANCE

Postpartum depression (PPD) affects as many as 20% of mothers, yet just 1 in 10 of these women receives evidence-based treatment. The COVID-19 pandemic has increased PPD risk, reduced treatment access, and shifted preferences toward virtual care.

OBJECTIVE

To determine whether an online 1-day cognitive behavioral therapy (CBT)-based workshop added to treatment as usual improves PPD, anxiety, social support, mother-infant relationship quality, and infant temperament more than treatment as usual alone.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial included 403 women with PPD who were recruited across Ontario, Canada, during the COVID-19 pandemic (April 20 to October 4, 2020). Women with Edinburgh Postnatal Depression Scale (EPDS) scores of at least 10 who were 18 years or older and had an infant younger than 12 months were eligible.

INTERVENTIONS

Women were randomly assigned to receive a live, interactive online 1-day CBT-based workshop delivered by a registered psychotherapist, psychiatrist, or clinical psychology graduate student in addition to treatment as usual (n = 202) or to receive treatment as usual and wait-listed to receive the workshop 12 weeks later (n = 201).

MAIN OUTCOMES AND MEASURES

The primary outcome was change in PPD (EPDS scores) in experimental and wait list control groups 12 weeks after baseline. Secondary outcomes included maternal anxiety (7-item Generalized Anxiety Disorder Questionnaire [GAD-7]), social support (Social Provisions Scale), quality of the mother-infant relationship (Postpartum Bonding Questionnaire), and infant temperament (Infant Behavior Questionnaire-Revised Very Short Form).

RESULTS

Participants all identified as women with a mean (SD) age of 31.8 (4.4) years. The workshop led to significant mean (SD) reductions in EPDS scores (from 16.47 [4.41] to 11.65 [4.83]; B = -4.82; P < .001) and was associated with a higher odds of exhibiting a clinically significant decrease in EPDS scores (odds ratio, 4.15; 95% CI, 2.66-6.46). The mean (SD) GAD-7 scores decreased from 12.41 (5.12) to 7.97 (5.54) after the workshop (B = -4.44; 95% CI, -5.47 to -3.38; P < .001) and participants were more likely to experience a clinically significant change (odds ratio, 3.09; 95% CI, 1.99-4.81). Mothers also reported improvements in bonding (B = -3.22; 95% CI, -4.72 to -1.71; P < .001), infant-focused anxiety (B = -1.64; 95% CI, -2.25 to 1.00; P < .001), social support (B = 3.31; 95% CI, 1.04 to 5.57; P < .001), and positive affectivity/surgency in infants (B = 0.31; 95% CI, 0.05 to 0.56; P < .001).

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial, an online 1-day CBT-based workshop for PPD provides an effective, brief option for mothers, reducing PPD and anxiety as well as improving social support, the mother-infant relationship, and positive affectivity/surgency in offspring.

Effects of maternal psychological stress during pregnancy on offspring brain development: Considering the role of inflammation and potential for preventive intervention

Heightened psychological stress during pregnancy has repeatedly been associated with increased risk for offspring development of behavior problems and psychiatric disorders. This review covers a rapidly growing body of research with the potential to advance a mechanistic understanding of these associations grounded in knowledge about maternal-placental-fetal stress biology and fetal brain development. Specifically, we highlight research employing magnetic resonance imaging to examine the infant brain soon after birth in relation to maternal psychological stress during pregnancy to increase capacity to identify specific alterations in brain structure and function and to differentiate between effects of pre- versus postnatal exposures. We then focus on heightened maternal inflammation during pregnancy as a mechanism through which maternal stress influences the developing fetal brain based on extensive preclinical literature and emerging research in humans. We place these findings in the context of recent work identifying psychotherapeutic interventions found to be effective for reducing psychological stress among pregnant individuals, which also show promise for reducing inflammation. We argue that a focus on inflammation, among other mechanistic pathways, has the potential to lead to a productive and necessary integration of research focused on the effects of maternal psychological stress on offspring brain development and prevention and intervention studies aimed at reducing maternal psychological stress during pregnancy. In addition to increasing capacity for common measurements and understanding potential mechanisms of action relevant to maternal mental health and fetal neurodevelopment, this focus can inform and broaden thinking about prevention and intervention strategies.

The effectiveness of psychological interventions for pregnant women with anxiety in the antenatal period: A systematic review

OBJECTIVE

Anxiety is a significant public health concern, that if untreated may lead to adverse outcomes for mother, baby and the family unit. The aim of this review was to determine the efficacy of psychological interventions for pregnant women with anxiety in the antenatal period. Although guidelines recommend psychological interventions for managing anxiety in the perinatal period, there is a lack of strong evidence on the most effective psychological intervention for use in the antenatal period. Effective non-pharmacological interventions are an important area that requires significant clinical attention.

DESIGN

A systematic review of quantitative and qualitative studies was conducted using Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, Applied Social Sciences Index and Abstracts (ASSIA), Web of Science and PsychInfo. Quality appraisal was performed using The Joanna Briggs Institute (JBI) critical appraisal tool to assess methodological quality on all six included papers. All four RCT's were assessed separately using the Cochrane Risk of Bias Tool.

FINDINGS

Of the 7278 articles, six quantitative studies were included. The overall results of this review found that mindfulness based interventions are by far the most effective intervention for the treatment of anxiety in the antenatal period. These findings are not in line with current guidance on treatment of women with anxiety in the antenatal period and warrants immediate attention.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

Healthcare professionals need to be aware of the potential benefits of mindfulness based interventions in practice. There is some evidence to support their use in the antenatal period, however, there remains insufficient evidence to confidently advocate for their use in practice. Follow-up research needs to be conducted on the efficacy of mindfulness based interventions on women with anxiety in the antenatal period using rigorous RCT's. Education and training of Midwives to help promote and use this intervention is recommended.

Cognitive-behavioural therapy for a variety of conditions: an overview of systematic reviews and panoramic meta-analysis

BACKGROUND

Cognitive-behavioural therapy aims to increase quality of life by changing cognitive and behavioural factors that maintain problematic symptoms. A previous overview of cognitive-behavioural therapy systematic reviews suggested that cognitive-behavioural therapy was effective for many conditions. However, few of the included reviews synthesised randomised controlled trials.

OBJECTIVES

This project was undertaken to map the quality and gaps in the cognitive-behavioural therapy systematic review of randomised controlled trial evidence base. Panoramic meta-analyses were also conducted to identify any across-condition general effects of cognitive-behavioural therapy.

DATA SOURCES

The overview was designed with cognitive-behavioural therapy patients, clinicians and researchers. The Cochrane Library, MEDLINE, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Child Development & Adolescent Studies, Database of Abstracts of Reviews of Effects and OpenGrey databases were searched from 1992 to January 2019.

REVIEW METHODS

Study inclusion criteria were as follows: (1) fulfil the Centre for Reviews and Dissemination criteria; (2) intervention reported as cognitive-behavioural therapy or including one cognitive and one behavioural element; (3) include a synthesis of cognitive-behavioural therapy trials; (4) include either health-related quality of life, depression, anxiety or pain outcome; and (5) available in English. Review quality was assessed with A MeaSurement Tool to Assess systematic Reviews (AMSTAR)-2. Reviews were quality assessed and data were extracted in duplicate by two independent researchers, and then mapped according to condition, population, context and quality. The effects from high-quality reviews were pooled within condition groups, using a random-effect panoramic meta-analysis. If the across-condition heterogeneity was I2 < 75%, we pooled across conditions. Subgroup analyses were conducted for age, delivery format, comparator type and length of follow-up, and a sensitivity analysis was performed for quality.

RESULTS

A total of 494 reviews were mapped, representing 68% (27/40) of the categories of the International Classification of Diseases, Eleventh Revision, Mortality and Morbidity Statistics. Most reviews (71%, 351/494) were of lower quality. Research on older adults, using cognitive-behavioural therapy preventatively, ethnic minorities and people living outside Europe, North America or Australasia was limited. Out of 494 reviews, 71 were included in the primary panoramic meta-analyses. A modest effect was found in favour of cognitive-behavioural therapy for health-related quality of life (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.05 to 0.50, I2 = 32%), anxiety (standardised mean difference 0.30, 95% confidence interval 0.18 to 0.43, prediction interval -0.28 to 0.88, I2 = 62%) and pain (standardised mean difference 0.23, 95% confidence interval 0.05 to 0.41, prediction interval -0.28 to 0.74, I2 = 64%) outcomes. All condition, subgroup and sensitivity effect estimates remained consistent with the general effect. A statistically significant interaction effect was evident between the active and non-active comparator groups for the health-related quality-of-life outcome. A general effect for depression outcomes was not produced as a result of considerable heterogeneity across reviews and conditions.

LIMITATIONS

Data extraction and analysis were conducted at the review level, rather than returning to the individual trial data. This meant that the risk of bias of the individual trials could not be accounted for, but only the quality of the systematic reviews that synthesised them.

CONCLUSION

Owing to the consistency and homogeneity of the highest-quality evidence, it is proposed that cognitive-behavioural therapy can produce a modest general, across-condition benefit in health-related quality-of-life, anxiety and pain outcomes.

FUTURE WORK

Future research should focus on how the modest effect sizes seen with cognitive-behavioural therapy can be increased, for example identifying alternative delivery formats to increase adherence and reduce dropout, and pursuing novel methods to assess intervention fidelity and quality.

Impact of an on-site perinatal mood disorders clinic in the diagnosis and management of perinatal mood disorders

Objectives To assess change in Edinburgh Postnatal Depression Scale (EPDS) scores in women treated at the Perinatal Mood Disorders Clinic (PMDC) as a measure of improvement in perinatal mood disorders (primary outcome), and treatment disposition at final visit. Methods Chart review was performed for all PMDC patients between March 1, 2017 and June 1, 2018 (n=120), as a self-controlled case series design. Two-tailed t-tests compared initial and final EPDS scores for all patients with >1 visit (n=64), where EPDS score of ≥13 indicated a positive screen for depression. A multivariable linear regression model with robust standard errors estimated the relationship between patient characteristics and final EPDS scores. Results Of 120 patients, n=56 had one visit and n=64 had >1 visit. Of these 64, mean final score (11.04) was lower than mean initial score (16.54; p<0.001). Additionally, certain patient characteristics were associated with higher final EPDS score, including history of mood disorder and treatment with both pharmacotherapy and psychotherapy. Conclusions Women treated at the PMDC showed improved EPDS scores when receiving at least two separate care visits. Therefore, the clinic may be filling a gap in access to timely care for women with perinatal mood disorders.

Chinese Taoist Cognitive Therapy for Symptoms of Depression and Anxiety in Adults in China: A Systematic Review and Meta-Analysis

Background: Chinese Taoist cognitive therapy (CTCT), a culture-oriented psychological therapy for Chinese mental well-being, has been proposed for decades. However, the evidence for its effects is unclear. This study aimed to systematically assess the effect of this therapy on symptoms of depression and anxiety in Chinese adults.

Methods: Relevant studies were searched from major electronic databases through November 2018 without language limits. Several search terms used include “anxiety” OR “depression” AND “Taoism” OR “Daoism” OR “Chinese Taoist Cognitive Therapy.” A total of 11 clinical trials focusing on CTCT were included in this meta-analysis. Random-effects meta-analytical models were conducted. Heterogeneity and publication bias were also explored.

Results: Eight clinical trials for 580 subjects were included. The majority of these studies explored samples with depressive symptoms. Overall, CTCT significantly reduced depressive symptoms with a small positive effect (SMD = 0.16, 95% CI: −0.36–0.68). Medium-to-large effect sizes were observed across individuals with clinical or non-clinical depression and chronic physical diseases (SMD = 0.70, 95%CI: 0.27–1.13 and SMD = 0.72, 95%CI: 0.09–1.35, respectively). However, the effectiveness for anxiety symptoms remains debatable.

Conclusions: Our findings hold promise that CTCT can help reduce depressive symptoms in Chinese adults, including patients with chronic physical diseases and clinical or non-clinical depression. Our findings may be generalized to Chinese communities in other countries.

Cognitive behavioral therapy for perinatal anxiety: A randomized controlled trial

BACKGROUND

Up to one in five women meet diagnostic criteria for an anxiety disorder during the perinatal period (i.e. pregnancy and up to 1 year postpartum). While psychotropic medications are effective, they are associated with risks for mothers and babies. There is a growing demand for evidence-based non-pharmacological treatments for perinatal anxiety.

OBJECTIVE

To evaluate the effectiveness of a cognitive behavioral group therapy protocol for perinatal anxiety.

METHODS

In total, 96 women were randomized to cognitive behavioral group therapy or waitlist at a clinic specializing in women's mental health. Participants were 22-41 years of age, pregnant or up to 6 months postpartum and had an anxiety disorder with or without comorbid depression.

RESULTS

Compared to waitlist, participants in cognitive behavioral group therapy reported significantly greater reductions in the primary outcome of anxiety (State-Trait Inventory of Cognitive and Somatic Anxiety, η²_p = .19; Hamilton Anxiety Rating Scale, η²_p = .16), as well as in secondary outcomes including worry (Penn State Worry Questionnaire, η²_p = .29), perceived stress (Perceived Stress Scale, η²_p = .33) and depressive symptoms (Edinburgh Postnatal Depression Scale, η²_p = .27; Montgomery-Åsberg Depression Rating Scale, η²_p = .11). Maternal status (pregnant, postpartum) and medication use were unrelated to treatment outcomes. All gains were maintained, or continued to improve, at 3-month follow-up.

CONCLUSION

Cognitive behavioral group therapy was effective in improving anxiety and related symptoms among women with anxiety disorders in the perinatal period.

Mental health care for parents of babies with congenital heart disease during intensive care unit admission: Systematic review and statement of best practice

INTRODUCTION

Congenital heart disease (CHD) is one of the most common causes of infant admission to pediatric intensive care and is associated with profound psychological stress for mothers, fathers and their infants. Intensive care unit admission represents an opportunity to offer evidence-based strategies to prevent or minimize severe psychological distress and promote secure bonding and attachment, alongside high-quality infant medical care.

OBJECTIVES

We aimed to identify, synthesize and critically appraise published evidence on the efficacy and cost-effectiveness of mental health interventions delivered in neonatal, pediatric or cardiac intensive care units for parents of infants with CHD. A secondary goal was to develop recommendations for advancing health policy, practice and research in the field.

METHODS

In accordance with a prospectively registered protocol (CRD42019114507), six electronic databases were systematically searched for studies reporting results of a controlled trial of a mental health intervention for parents of infants aged 0-12 months with a congenital anomaly requiring intensive care unit admission. To maximize generalizability of results, trials involving infants with any type of structural congenital anomaly requiring surgery were included. Outcomes included intervention type, process, efficacy, and cost-effectiveness.

RESULTS

Across all forms of congenital anomaly, only five trials met inclusion criteria (four in CHD, one in gastrointestinal malformation). All interventions engaged parents face-to-face, but each had a distinct therapeutic approach (parent-infant interaction and bonding, early pediatric palliative care, psycho-education, parenting skills training, and family-centered nursing). Four of the five trials demonstrated efficacy in reducing maternal anxiety, although the quality of evidence was low. Positive results were also found for maternal coping, mother-infant attachment, parenting confidence and satisfaction with clinical care, as well as infant mental (but not psychomotor) development at 6 months. Mixed results were found for maternal depression and infant feeding. No evidence of efficacy was found for improving parent, infant or family quality of life, physical health or length of infant hospital stay, and there were no data on cost-effectiveness.

CONCLUSIONS

Stronger evidence for the efficacy of mental health interventions to buffer the effects of intensive care unit admission for parents of infants with CHD is urgently needed. Robust, high-quality trials are lacking, despite the established need and demand, and health policies prioritizing parent mental health care in the context of early childhood adversity are needed.
