Urinary 1H NMR Metabolomic Analysis of Prenatal Maternal Stress Due to a Natural Disaster Reveals Metabolic Risk Factors for Non-Communicable Diseases: The QF2011 Queensland Flood Study.

Prenatal stress alters fetal programming, potentially predisposing the ensuing offspring to long-term adverse health outcomes. To gain insight into environmental influences on fetal development, this QF2011 study evaluated the urinary metabolomes of 4-year-old children (n = 89) who were exposed to the 2011 Queensland flood in utero. Proton nuclear magnetic resonance spectroscopy was used to analyze urinary metabolic fingerprints based on maternal levels of objective hardship and subjective distress resulting from the natural disaster. In both males and females, differences were observed between high and low levels of maternal objective hardship and maternal subjective distress groups. Greater prenatal stress exposure was associated with alterations in metabolites associated with protein synthesis, energy metabolism, and carbohydrate metabolism. These alterations suggest profound changes in oxidative and antioxidative pathways that may indicate a higher risk for chronic non-communicable diseases such obesity, insulin resistance, and diabetes, as well as mental illnesses, including depression and schizophrenia. Thus, prenatal stress-associated metabolic biomarkers may provide early predictors of lifetime health trajectories, and potentially serve as prognostic markers for therapeutic strategies in mitigating adverse health outcomes.

Assessing the relationship between psychosocial risk and pregnancy outcomes using the perinatal integrated psychosocial assessment (PIPA) tool.

BACKGROUND: The Perinatal Integrated Psychosocial Assessment (PIPA) tool screens for anxiety, depression, and psychosocial factors in pregnancy. We aimed to assess the association between PIPA-determined psychosocial risk and obstetric and neonatal outcomes. METHODS: Cohort study of all pregnant women who gave birth at ≥20 weeks of gestation in 2017-2019 at a tertiary maternity hospital in, Sydney, Australia. Women completed PIPA at their first antenatal visit and were assigned a PIPA risk category. At-risk women were reviewed and referred for support. The association between PIPA risk category and obstetric and neonatal outcomes was evaluated using multivariable logistic regression adjusting for sociodemographic and pregnancy factors. RESULTS: In all, 5969 women completed PIPA; 71.4% were assessed no/low risk, 17.5% medium risk, and 11.1% medium-high/high risk. Compared with no/low-risk women, medium-high/high-risk women were more likely to remain in hospital for >72 hours (aOR 1.47 [95% CI 1.33-1.64]); to not be breastfeeding at discharge (aOR 1.77 [95% CI 1.20-2.61]); to have their infants experience birth complications (aOR 1.24 [95% CI 1.03-1.50]); and to be admitted to the NICU (aOR 1.63 [95% CI 1.26-2.11]). There was a modest increase in odds of cesarean birth (aOR 1.12 [95% CI 1.00-1.27]), and no association with preterm birth or low birthweight. The risk of adverse outcomes disappeared for medium-high/high-risk women referred for support. CONCLUSIONS: The PIPA tool identified one in 10 women at high psychosocial risk with increased risk of adverse obstetric and neonatal outcomes. Adverse outcomes were attenuated for high-risk women who were referred for extra support, suggesting that psychosocial review and referral for high-risk women may reduce the risk of adverse obstetric and neonatal outcomes.

The clinical performance and cost-effectiveness of two psychosocial assessment models in maternity care: The Perinatal Integrated Psychosocial Assessment study.

PROBLEM: Although perinatal universal depression and psychosocial assessment is recommended in Australia, its clinical performance and cost-effectiveness remain uncertain. AIM: To compare the performance and cost-effectiveness of two models of psychosocial assessment: Usual-Care and Perinatal Integrated Psychosocial Assessment (PIPA). METHODS: Women attending their first antenatal visit were prospectively recruited to this cohort study. Endorsement of significant depressive symptoms or psychosocial risk generated an 'at-risk' flag identifying those needing referral to the Triage Committee. Based on its detailed algorithm, a higher threshold of risk was required to trigger the 'at-risk' flag for PIPA than for Usual-Care. Each model's performance was evaluated using the midwife's agreement with the 'at-risk' flag as the reference standard. Cost-effectiveness was limited to the identification of True Positive and False Positive cases. Staffing costs associated with administering each screening model were quantified using a bottom-up time-in-motion approach. FINDINGS: Both models performed well at identifying 'at-risk' women (sensitivity: Usual-Care 0.82 versus PIPA 0.78). However, the PIPA model was more effective at eliminating False Positives and correctly identifying 'at-risk' women (Positive Predictive Value: PIPA 0.69 versus Usual Care 0.41). PIPA was associated with small incremental savings for both True Positives detected and False Positives averted. DISCUSSION: Overall PIPA performed better than Usual-Care as a psychosocial screening model and was a cost-saving and relatively effective approach for detecting True Positives and averting False Positives. These initial findings warrant evaluation of longer-term costs and outcomes of women identified by the models as 'at-risk' and 'not at-risk' of perinatal psychosocial morbidity.

Patterns of psychiatric admission in Australian pregnant and childbearing women.

PURPOSE: The early postnatal period is a time of increased risk for psychiatric admission. However, there is scope to further examine if this increase in risk extends to the entire perinatal period (pregnancy and first postnatal year), and how it compares to admission outside of the perinatal period. METHODS: Data were linked across birth and hospital admission registers from July 2000 to December 2009. The study cohort, consisting of all pregnant and childbearing women with a psychiatric history, was divided into two groups: case women (at least one perinatal principal psychiatric admission in the study period) (38%) and comparison women (no perinatal principal psychiatric admissions) (62%). Outcomes were admission rate and length of stay adjusted for diagnosis, socio-demographic factors and timing of admission. RESULTS: Antenatal and postnatal admissions rates were both higher than non-perinatal admission rates for case women for all diagnoses. There was little evidence that women with perinatal admissions were at an increased risk of admissions at other times. Socially disadvantaged women had significantly fewer and shorter admissions than their respective counterparts. CONCLUSIONS: The entire perinatal period is a time of increased risk for admission across the range of psychiatric disorders, compared to other times in a woman's childbearing years. Reduced admission rate and length of stay for socially disadvantaged women suggest lack of equity of access highlighting the importance of national perinatal mental health policy initiatives inclusive of disadvantaged groups.

Screening for anxiety disorders in third trimester pregnancy: a comparison of four brief measures.

Evidence regarding the accuracy of existing anxiety screeners used in pregnancy is limited. This study compares the psychometric characteristics of the Generalized Anxiety Disorder 2- and 7-item Scales (GAD-2 and GAD-7), the anxiety subscale of the Edinburgh Postnatal Depression Scale (EPDS-3A) and the two anxiety items of the Antenatal Risk Questionnaire (ANRQ-2A). Nine hundred fifty-four women completed the screening measures and anxiety modules of a diagnostic reference standard (SAGE-SR) in the third trimester. Test performance characteristics of each measure was assessed using Receiver Operator Characteristic (ROC) analysis. We applied four previously recommended criteria to ascertain the value of each measure for widespread clinical use: area under the curve (AUC ≥ 0.8, Youden's index ≥ 0.5, negative predictive value (NPV) ≥ 0.8 and positive likelihood ratio (LR +) ≥ 4.0). Prevalence for any SAGE-SR anxiety disorder was 3%. All measures yielded an acceptable AUC of ≥ 0.8, Youden's index of ≥ 0.5 and NPV of ≥ 0.8. Only the EPDS-3A, at a cut-point ≥ 5, also achieved a LR + of ≥ 4.0 (4.35) but at this cut-point sensitivity was less than 0.75. The ANRQ-2A, at its optimal cut-point of ≥ 6, was the only measure to additionally attain both a sensitivity and specificity of ≥ .75. This study expands the evidence base for brief anxiety screening measures in the maternity setting and provides empirical support for the use of the EPDS-3A and ANRQ-2A in routine screening programmes. Studies assessing the performance of these measures in samples with higher disease prevalence and broader socio-economic status are warranted.

Why do some pregnant women not fully disclose at comprehensive psychosocial assessment with their midwife?

PROBLEM: While comprehensive psychosocial assessment is recommended as part of routine maternity care, unless women engage and disclose, psychosocial risk will not be identified or referred in a timely manner. We need to better understand and where possible overcome the barriers to disclosure if we are to reduce mental health morbidity and complex psychosocial adversity. AIMS: To assess pregnant women's attitude to, and reasons for non-disclosure at, comprehensive psychosocial assessment with their midwife. METHODS: Data from 1796 pregnant women were analysed using a mixed method approach. After ascertaining women's comfort with, attitude to, and non-disclosure at psychosocial screening, thematic analysis was used to understand the reasons underpinning non-disclosure. FINDINGS: 99% of participants were comfortable with the assessment, however 11.1% (N = 193) reported some level of nondisclosure. Key themes for non-disclosure included (1) Normalising and negative self-perception, (2) Fear of negative perceptions from others, (3) Lack of trust of midwife, (4) Differing expectation of appointment and (5) Mode of assessment and time issues. DISCUSSION: Factors associated with high comfort and disclosure levels in this sample include an experienced and skilled midwifery workforce at the study site and a relatively advantaged and mental health literate sample. Proper implementation of psychosocial assessment policy; setting clear expectations for women and, for more vulnerable women, extending assessment time, modifying mode of assessment, and offering continuity of midwifery care will help build rapport, improve disclosure, and increase the chance of early identification and intervention. CONCLUSIONS: This study informs approaches to improving comprehensive psychosocial assessment in the maternity setting.

Disclosure of sensitive material at routine antenatal psychosocial assessment: The role of psychosocial risk and mode of assessment.

PROBLEM: While routine psychosocial assessment is acceptable to most pregnant women, some women will not fully disclose psychosocial concerns to their clinician. AIMS: To assess the impact of psychosocial risk, current symptoms and mode of assessment on women's honesty of disclosure at psychosocial assessment. METHODS: Logistic regression was used to examine associations between disclosure and a range of psychosocial characteristics in women who were 'always honest' and 'not always honest'. Mixed ANOVAs were used to test the influence of mode of assessment and honesty on scores on a repeated measure of psychosocial risk. FINDINGS: 10.8% (N=193 of 1788) of women did not fully disclose at psychosocial assessment. Non-disclosure was associated with a mental health history (aOR=1.78, 95%CI: 1.18-2.67, p<0.01) and lack of social and partner support (aOR=1.74, 95%CI: 1.16-2.62, p<0.05; aOR=2.08, 95%CI: 1.11-3.90, p<0.05, respectively). Those reporting not always being honest at face to face assessment showed a greater increase in psychosocial risk score when the assessment was repeated online via self-report, compared to women who were always honest. DISCUSSION: A history of mental health issues and lack of social and partner support are associated with reduced disclosure at face to face assessment. Online self-report assessment may promote greater disclosure, however this should always be conducted in the context of clinician feedback. CONCLUSION: Greater psychosocial vulnerability is associated with a lower likelihood of full disclosure. Preliminary findings relating to mode of assessment warrant further exploration within a clinical context.

Supporting routine psychosocial assessment in the perinatal period: The concurrent and predictive validity of the Antenatal Risk Questionnaire-Revised.

BACKGROUND: Australian clinical practice guidelines support comprehensive psychosocial assessment as a routine component of maternity care. AIM: To examine the concurrent and predictive validity of the Antenatal Risk Questionnaire-Revised (ANRQ-R) when used across the perinatal period. METHODS: Women completed the ANRQ-R and a diagnostic reference standard (SAGE-SR) in the second and third trimesters and at 3-months postpartum. ANRQ-R test performance for cut-off scores at each time-point was assessed using Receiver Operator Characteristic (ROC) analysis. FINDINGS: Overall sample sizes were N=1166 (second trimester), N=957 (third trimester) and N=796 (3-month postpartum). 6.5%, 5.6% and 6.2% of women met SAGE-SR criteria for any depressive or anxiety disorder at these time-points ('cases'), respectively. ROC analysis yielded acceptable areas under the curve (AUC) when the ANRQ-R was used to detect current (AUC=0.789-0.798) or predict future (AUC=0.705-0.789) depression or anxiety. Using an example cut-off score of 18 or more, the ANRQ-R correctly classified 72-76% of concurrent 'cases' and 'non-cases' (sensitivity=0.70-0.74, specificity=0.72-0.76) and correctly predicted 74-78% of postnatal 'cases' and 'non-cases' (sensitivity=0.52-0.72, specificity=0.75-0.79). Completion of the ANRQ-R earlier in pregnancy yielded greater positive likelihood ratios for predicting depression or anxiety at 3-months postpartum (cut-off ≥18: second trimester=3.8; third trimester=2.2). CONCLUSION: The ANRQ-R is a structured psychosocial assessment questionnaire that can be scored to provide an overall measure of psychosocial risk. Cut-off scores need not be uniform across settings. Such decisions should be guided by factors including diagnostic prevalence rates, local needs and resource availability.

Increases in use of Medicare Benefits Schedule mental health items among women who gave birth in New South Wales, 2009-2015.

OBJECTIVE: To report rates of Medicare Benefits Schedule (MBS) mental health item use among a sample of women who gave birth in NSW (2009-2015) and examine if the SAFE START policy increased use of these items among perinatal women. METHODS: Data was drawn from women participating in the Australian Longitudinal Study on Women's Health 1973-1978 cohort, linked to data from the NSW Perinatal Data Collection and MBS. RESULTS: Use of Medicare-subsidised mental health items increased 2.7-fold among perinatal women (n=1,453) between 2009 and 2015 (4.1% versus 11.0% respectively), compared to a 1.3-fold increase among non-perinatal women (n=1,800, 6.3% versus 8.4% respectively). However, the increased use of MBS mental health items among perinatal women was not observed to be impacted by the SAFE START policy, after accounting for time trends. CONCLUSION: There was a substantial increase in the use of MBS mental health items among women in NSW between 2009 and 2015, with a more pronounced increase among women who had given birth compared to those who had not. Implications for public health: This study provides important information about changes in mental health service use during a time of significant investment in perinatal mental health, and demonstrates the value of longitudinal survey data linked with administrative health data to evaluate the impact of health policy.

The antenatal risk questionnaire-revised: Development, use and test-retest reliability in a community sample of pregnant women in Australia.

BACKGROUND: Routine psychosocial assessment during pregnancy and the first postnatal year is a public health strategy that prioritises early identification of known risk factors for poor perinatal mental health. We aimed to report on the development and use of the Antenatal Risk Questionnaire-Revised (ANRQ-R), contribute normative data for a community sample of pregnant women and examine its test-retest reliability. METHODS: The ANRQ-R was developed in consultation with an expert advisory group. Women completed the ANRQ-R with their midwife at their first antenatal appointment. Test-retest analysis was restricted to women who consented to follow-up and completed a repeat ANRQ-R within four weeks. RESULTS: 7183 women completed the ANRQ-R (total score M = 12.05, Mdn=10; range =5-49). There were some statistically significant differences in total score across maternal age group (χ2=69.75, p<.001), country of birth (χ2=144.01, p<.001) and socioeconomic quintiles (χ2=20.13, p<.001), however the effect sizes of all differences were either small or not clinically significant. Test-retest reliability for the ANRQ-R total score was good (N = 1670; ICC=0.77). Item-level test-retest reliabilities were moderate to good (ICC range=0.65-0.80; kappa coefficient range=0.31-0.74). LIMITATIONS: The study was conducted at a single site. Although there was significant diversity in terms of maternal age and country of birth, the majority of participants were partnered and resided in socio-economically advantaged areas, limiting the generalisability of results. CONCLUSIONS: This study contributes significant normative data for the ANRQ-R and offers valuable insights for clinicians and researchers working with particular sub-groups of the perinatal population. Additional psychometric examination of the ANRQ-R, including its concurrent and predictive validity, is required.

Attitudes and Engagement of Pregnant and Postnatal Women With a Web-Based Emotional Health Tool (Mummatters): Cross-sectional Study.

BACKGROUND: Mummatters is a web-based health tool that allows women to self-assess the symptoms of depression and the presence of psychosocial risk factors throughout pregnancy and the postnatal period. It aims to increase women's awareness of their own symptoms or risk factors and their knowledge of the available support options, to encourage engagement with these support options (as appropriate), and to facilitate communication about emotional health issues between women and their health care providers. OBJECTIVE: The aim of this study is to report the uptake of mummatters; the sociodemographic and psychosocial risk profiles of a subsample of users; and the acceptability, credibility, perceived effect, and motivational appeal of the tool. The help-seeking behaviors of the subsample of users and barriers to help seeking were also examined. METHODS: Mummatters was launched in November 2016. Women who completed the mummatters baseline assessment were invited to complete a web-based follow-up survey 1 month later. RESULTS: A total of 2817 women downloaded and used mummatters between November 13, 2016, and May 22, 2018, and 140 women participated in the follow-up study. Approximately half of these women (51%; 72/140) were Whooley positive (possible depression), and 43% (60/140) had an elevated psychosocial risk score on the Antenatal Risk Questionnaire. Mummatters was rated favorably by pregnant and postnatal women in terms of its acceptability (94%-99%), credibility (93%-97%), appeal (78%-91%), and potential to affect a range of health behaviors specific to supporting emotional wellness during the perinatal period (78%-93%). Whooley-positive women were more likely to speak with their families than with a health care provider about their emotional health. Normalizing symptoms and stigma were key barriers to seeking help. CONCLUSIONS: Although mummatters was rated positively by consumers, only 53% (19/36) to 61% (22/36) of women with possible depression reported speaking to their health care providers about their emotional health. There was a trend for more prominent barriers to seeking help among postnatal women than among pregnant women. Future studies that investigate whether social barriers to seeking help are greater once a woman has an infant are warranted. Such barriers potentially place these women at greater risk of remaining untreated, as the demands on them are greater.

Honesty and comfort levels in mothers when screened for perinatal depression and anxiety.

PURPOSE: To evaluate the degree of honesty and level of comfort reported by women when questioned about their emotional wellbeing during the perinatal period; to investigate if honesty and comfort are associated with perinatal depression or perinatal anxiety; and to examine the reasons why women may not always respond honestly. METHODS: Qualitative and quantitative data from 1597 women from the cross-sectional perinatal mental health substudy (part of the Australian Longitudinal Study on Women's Health) were analysed using a mixed methods approach. RESULTS: When questioned by their health practitioner about their emotional wellbeing in the perinatal period, 20.7% of women indicated they had not always responded honestly. Reasons for not being honest reflected four main themes: normalizing of symptoms/coping; negative perceptions (self-and others); fear of adverse repercussions; and fear of involvement of health services (trust and confidentiality). The 38.9% of women who did not feel comfortable when questioned by their health practitioner about their emotional wellbeing were four times more likely to report perinatal depression (odds ratio = 4.09; 95% confidence interval = 2.55, 6.57) and nearly twice as likely to report perinatal anxiety (odds ratio = 1.90; 95% confidence interval = 1.24, 2.94) than other women. CONCLUSIONS: Women who are most likely to need mental health care during the perinatal period are also those least likely to be honest about their mental health. A non-judgemental, open and reassuring approach by clinicians may help to reduce the stigma and fears contributing to lack of honest responses, and improve early diagnosis and treatment of mental health problems.

Adversity in childhood and depression in pregnancy.

Adverse childhood experiences (ACEs) have been found to be associated with various health conditions; however, there is dearth of evidence on the relationship between ACEs and prenatal depression. This study was conducted to determine the association between overall ACE score and prenatal depression symptoms, assess the moderating effect of social support and partner support on this relationship, and determine the association between individual ACE scores and prenatal depression. A secondary analysis was conducted of data from an RCT that assessed the feasibility of e-screening for maternal mental health among 636 pregnant women recruited from antenatal clinics. Two logistic regression models were built to reach our objectives. Over 80% of the participants were older than 25 years and had education beyond high school. Eighteen percent of the women had an ACE score of four or more. Univariable analysis found a 2.5-fold increase in the odds of prenatal depression for women with an ACEs score of ≥ 4. When examining the overall ACE score, lack of social support during pregnancy [AOR = 4.16; 95%CI (2.10-10.35)] and partner's relationship [AOR = 2.23; 95%CI (1.12-4.44)] were associated with prenatal depression while among the individual ACE scores, living with a person who went to prison was found to be associated with prenatal depression even when controlled for all variables. No moderating effect was found. These findings suggest for the improvement of partner's relationship and provision of social support before women conceive, in order to mitigate the effect of these adversities.

A narrative review of studies addressing the clinical effectiveness of perinatal depression screening programs.

BACKGROUND: Clinical practice guidelines recommend that women be screened for depression as a routine component of maternity care however there is ongoing debate about the benefits of depression screening programs in this context. AIM: This narrative review identifies and describes the clinical effectiveness of perinatal depression screening programs in relation to one or more of the following interrelated domains: referral for additional mental health support or treatment; engagement with mental health support or treatment options; and, maternal mental health or parenting outcomes. METHODS: English-language studies, published up to July 2017, were identified and their methodological quality was assessed. RCTs and non-RCTs were included. RESULTS: Overall, the majority of the fourteen studies identified showed that participation in a perinatal depression screening program increases referral rates and service use, and is associated with more optimal emotional health outcomes. One of four available studies demonstrated an improvement in parenting outcomes as a result of participation in an integrated postnatal depression screening program. CONCLUSION: This small but important body of work is integral to the continuing debate over the merits of screening for depression in the perinatal period. Current evidence favours the overall benefits of perinatal depression screening programs across the three focus areas of this review. Future research should consider a woman's broader psychosocial context and should address the economic as well as clinical outcomes of these programs. Rigorous evaluation of emerging digital approaches to perinatal depression screening is also required.

Insights into implementation of routine depression screening and psychosocial assessment in a private hospital setting: A qualitative study.

BACKGROUND: Studies continue to show that women who give birth in the private maternity sector are less likely to receive depression screening and psychosocial assessment as a routine component of maternity care. However, examples of successfully implemented routine psychosocial assessment programs are beginning to emerge, and there is great value in better understanding the factors that can contribute to the successful delivery of emotional health care in this context. AIM: The aim of this study was to identify factors that facilitated successful implementation of antenatal psychosocial assessment in a private hospital setting. METHODS: This study employed a qualitative research design. Semi-structured interviews were used to explore the views and experiences of health professionals involved in implementation of the program at the participating site. RESULTS: Nine health professionals participated in the study (three midwives, three obstetricians, two managers and one mental health worker). Factors that facilitated successful implementation of the program were reflected in five key themes: (i) multidisciplinary support for the program; (ii) training and clinical supervision; (iii) allocation of sufficient resources; (iv) availability of local referral pathways; and (v) normalisation of the process. CONCLUSION: This study shows that barriers to implementation of perinatal depression screening and psychosocial assessment are surmountable and will provide confidence to other services, that routine 'mental health assessment' as required under updated Medical Benefits Scheme items for obstetric services, can be successfully implemented and sustained in private hospital settings.

Trajectories of clinical and parenting outcomes following admission to an inpatient mother-baby unit.

BACKGROUND: This study aimed to examine trajectories of clinical and parenting outcomes following admission to a mother-baby unit (MBU), and to explore factors associated with these trajectories. METHODS: Women admitted to an MBU completed the Edinburgh Postnatal Depression Scale (EPDS), Depression, Anxiety and Stress Scale (DASS-21), Karitane Parenting Confidence Scale (KPCS) and Maternal Postnatal Attachment Scale (MPAS) at admission, discharge and 3 months following discharge. Questions assessing psychosocial risk and adult attachment style were also completed at admission, and information relating to service engagement in the time since discharge was collected at follow-up. Additional clinical and demographic information was extracted from the patient medical record. RESULTS: Seventy-five women participated in the study. Overall, significant improvements in mean scores on measures of anxiety and parenting confidence were maintained 3-months following discharge. However, the majority of women (93.3%) followed trajectories that were characterised by deterioration in self-reported mother-infant attachment following discharge. 62.9 and 34.6% of women followed trajectories of increased symptoms of depression and stress between discharge and follow-up, respectively. Across measures, the least optimal trajectories, or least optimal scores, at follow-up were associated with less secure maternal attachment style (associated with more anxiety symptoms, poorer parenting confidence and maternal-infant attachment), older maternal age (more depressive symptoms) and increased psychosocial risk (more anxiety symptoms). CONCLUSIONS: The findings of this study highlight the clinical implications of anxious attachment style for the mental health and parenting outcomes of women admitted to an MBU and the importance of incorporating mother-infant therapy as part of an ongoing management plan. Comprehensive discharge planning and transitional care to help ensure women discharged from an MBU are best supported in the longer term is recommended.

'Singing with your baby': an evaluation of group singing sessions for women admitted to a specialist mother-baby unit.

This paper reports on the acceptability, experience of participation and the immediate impact on maternal mood state of group singing sessions, introduced as a routine component of a mother-baby unit (MBU) treatment programme. Data was collected from 27 women who participated in the pilot programme. Results showed that implementation of a singing intervention in this setting is positively appraised by women and is associated with positive changes in self-reported mood state from pre- to post-session. Key facilitators and barriers to the success of the programme and directions for future research are discussed.

Policy Impacts of the Australian National Perinatal Depression Initiative: Psychiatric Admission in the First Postnatal Year.

This paper helps to quantify the impact of the Australian National Perinatal Depression Initiative (NPDI) on postnatal inpatient psychiatric hospitalisation. Based on individual hospital admissions data from New South Wales and Western Australia, we found that the NPDI reduced inpatient psychiatric hospital admission by up to 50% [0.9% point reduction (95% CI 0.70-1.22)] in the first postnatal year. The greatest reduction was observed for adjustment disorders. The NPDI appears to be associated with fewer post-birth psychiatric disorders hospital admissions; this suggests earlier detection of psychiatric disorders resulting in early care of women at risk during their perinatal period.

A randomized controlled trial of 'MUMentum Pregnancy': Internet-delivered cognitive behavioral therapy program for antenatal anxiety and depression.

BACKGROUND: Anxiety and depression are common during pregnancy and associated with adverse outcomes for the mother and infant if left untreated. Despite the need to improve treatment accessibility and uptake in this population, no studies have investigated internet-delivered cognitive behavioural therapy (iCBT) for antenatal anxiety and depression. In a randomised controlled trial, we examined the efficacy and acceptability of a brief, unguided iCBT intervention - the MUMentum Pregnancy program - in pregnant women with anxiety and/or depression. METHODS: Participants meeting clinical threshold on validated self-report measures of generalised anxiety and/or depression were recruited online and randomised to iCBT (n = 43) or a treatment as usual (TAU) control (n = 44). Outcomes were assessed at baseline, post-treatment and four-week follow-up; and included anxiety, depression, psychological distress, antenatal bonding, quality of life, and treatment acceptability. RESULTS: Of the 36 women who started iCBT, 26 completed all three lessons of treatment (76% adherence rate). iCBT produced moderate to large effect size reductions for anxiety on the GAD-7 (Hedges' g = 0.76) and psychological distress on the Kessler-10 (g = 0.88) that were superior to TAU. Only small nonsignificant differences were found for depression outcomes (g = < 0.35). Participants reported that iCBT was an acceptable treatment for antenatal anxiety and/or depression. LIMITATIONS: Lack of an active control condition and long-term postpartum follow-up. CONCLUSIONS: This is the first study to evaluate brief unguided iCBT for antenatal anxiety and depression. While our findings are promising, particularly for anxiety reduction, additional RCTs are required to establish treatment efficacy.
