An integrated community mental healthcare program to reduce suicidal ideation and improve maternal mental health during the postnatal period: the findings from the Nagano trial

Suicide Interventions in Spain and Japan: A Comparative Systematic Review

(1) Background: This systematic review presents an overview of psychological interventions in suicide published between 2013 and 2023 in Spain and Japan, sparked by Spain's alarming recent increase in suicide rates and the potential exemplar of Japan's reduction efforts. (2) Methods: Following the PRISMA checklist, the databases Web of Science, Scopus, PubMed, and PsycInfo were searched using the terms [("suicide" OR "suicidal behavior" OR "suicidal attempt" OR "suicidal thought" OR "suicidal intention") AND ("prevention" OR "intervention" OR "psychosocial treatment" OR "Dialectical Behavior Therapy" OR "Cognitive Therapy" OR "psychotherap*")] AND [("Spain" OR "Spanish") OR ("Japan" OR "Japanese")]. We included articles published in peer-reviewed academic journals, written in English, Spanish, and Japanese between 2013 and 2023 that presented, designed, implemented, or assessed psychological interventions focused on suicidal behavior. (3) Results: 46 studies were included, concerning prevention, treatment, and training interventions. The risk of bias was low in both Spanish and Japanese studies, despite the lack of randomization of the samples. We identified common characteristics, such as psychoeducation and coping skills. Assertive case management was only highlighted in Japan, making an emphasis on active patient involvement in his/her care plan. (4) Conclusions: The findings will help professionals to incorporate into their interventions broader, more comprehensive approaches to consider more interpersonal components.

Birth and early parenting during the COVID-19 pandemic: A cross-sectional study in the Austrian and German population

BACKGROUND

During the COVID-19 pandemic, new mothers and their babies represent a particularly vulnerable group. This study investigates the effects of the pandemic on the pregnancy and childbirth experience, as well as on postnatal stress and depression levels.

METHODS

An online survey was completed by 1964 Austrian and German mothers who gave birth during the COVID-19 pandemic. The survey included the Pregnancy Distress Questionnaire (PDQ), the Childbirth Experience Questionnaire (CEQ), the Edinburgh Postnatal Depression Score (EPDS), the Perceived Stress Score (PSS), and additional pregnancy- and pandemic-related questions. We conducted multilinear regression models in order to investigate which factors predict childbirth experience, stress and depression scores.

FINDINGS

There was a high prevalence of depression symptoms (42%), though the mean EPDS score was 8·71 (SD = 5·70), below the cut-off for depression of 10. The prevalence of high stress scores was 9%, and the mean PSS score was 17·7 (SD = 6·64), which indicates moderate perceived stress. The pandemic reduced the time spent with grandparents, as well as the help received by the mother from relatives and friends. Not receiving help was associated with higher stress and depression scores. In the multilinear regression models, the most important predictor for a negative childbirth experience was a high-risk pregnancy, while the strongest predictors for high stress and depression levels were low social support and negatively perceived pandemic repercussions on financial, social or health aspects of family life.

INTERPRETATION

The results suggest that the pandemic had an impact on maternal mental health. While the perceived consequences due to the pandemic negatively affected the postnatal depression and stress levels, perceived social support acted as a protective factor.

Effectiveness of mHealth consultation services for preventing postpartum depressive symptoms: a randomized clinical trial

BACKGROUND

Although many conventional healthcare services to prevent postpartum depression are provided face-to-face, physical and psychosocial barriers remain. These barriers may be overcome by using mobile health services (mHealth). To examine the effectiveness of mHealth professional consultation services in preventing postpartum depressive symptoms in real-world settings, we conducted this randomized controlled trial in Japan, where universal free face-to-face perinatal care is available.

METHODS

This study included 734 pregnant women living in Yokohama city who could communicate in Japanese, recruited at public offices and childcare support facilities. The participants were randomized to the mHealth group (intervention, n = 365), where they could use a free app-based mHealth consultation service with gynecologists/obstetricians, pediatricians, and midwives whenever and as many times as they wanted between 6 p.m. and 10 p.m. on weekdays throughout their pregnancy and postpartum periods (funded by the City of Yokohama government) or the usual care group (control, n = 369). The primary outcome was the risk of elevated postpartum depressive symptoms, defined as Edinburgh Postnatal Depression Scale score ≥ 9. Secondary outcomes were self-efficacy, loneliness, perceived barriers to healthcare access, number of clinic visits, and ambulance usage. All outcomes were collected three months post-delivery. We also conducted subgroup analyses assessing the differences in the treatment effect by sociodemographic status.

RESULTS

Most women completed all questionnaires (n = 639 of 734, response rate: 87%). The mean baseline age was 32.9 ± 4.2 years, and 62% were primipara. Three months post-delivery, women in the mHealth group had a lower risk of elevated postpartum depressive symptoms (47/310 [15.2%]) compared to the usual care group (75/329 [22.8%], risk ratio: 0.67 [95% confidence interval: 0.48-0.93]). Compared with the usual care group, women in the mHealth group had higher self-efficacy, less loneliness, and fewer perceived barriers to healthcare access. No differences were observed in the frequency of clinic visits or ambulance usage. Furthermore, in the subgroup analyses, we did not find differences in the treatment effect by sociodemographic status.

CONCLUSIONS

Local government-funded mHealth consultation services have a preventive effect on postpartum depressive symptoms, removing physical and psychological barriers to healthcare access in real-world settings.

Measures of suicidality in perinatal women: A systematic review

BACKGROUND

Suicide is a leading cause of death for perinatal women. Identifying women at risk of suicide is critical. Research on the validity and/or reliability of measures assessing suicidality in perinatal women is limited. This review sought to: (1) identify; and (2) evaluate the psychometric properties of suicidality measures validated in perinatal populations.

METHODS

Nine electronic databases were systematically searched from inception to January 2022. Additional articles were identified through citation tracking. Study quality was assessed using an adapted tool, and the psychometric properties of measures were reviewed and presented using a narrative synthesis.

RESULTS

A total of 208 studies were included. Thirty-five studies reported psychometric data on ten suicidality measures. Fifteen studies reported both validity and reliability data, 12 reported more than one type of validity, seven validated more than one measure and four only reported reliability. Nearly all measures primarily screened for depression, with an item or subscale assessing suicidal ideation and/or behaviours. Three measures were specifically developed for perinatal women, but only two were validated in more than one study. The Postpartum Depression Screening Scale (PDSS), suicidal thoughts subscale, was validated most frequently.

LIMITATIONS

Methodological differences and variability between the measures (e.g., suicidality construct assessed, number of items and administration) precluded direct comparisons.

CONCLUSION

Further validation of suicidality measures is needed in perinatal women. Screening for perinatal suicidality often occurs in the context of depression. The development of a standalone measure specifically assessing suicidality in perinatal women may be warranted, particularly for use in maternity care settings.

Developing an obstetric care screening tool to improve social support access for pregnant women: A prospective cohort study

Background

This study aimed to develop an efficient interview sheet during pregnancy and screening tool to identify pregnant women needing social support at obstetric institutions. Moreover, we investigate the perinatal factors associated with the Edinburgh postnatal depression scale (EPDS).

Methods

This prospective cohort study was conducted at three medical institutions that commonly encounter cases with social issues. Pregnant women were assessed using an interview sheet at the first visit (n = 678), at approximately 28 weeks gestation (n = 495), 36 weeks gestation (n = 296), and the postpartum period (n = 822). We investigated the important items identified on the new screening questionnaire (NEW interview sheets) for women needing social support. The items on the interview sheet were scored by multiple linear regression analysis, and the cutoff values were calculated using the receiver operating characteristic curve. The association between perinatal factors and EPDS was assessed using multiple logistic regression analyses.

Results

The study included 166 cases for which all NEW interview sheets for all periods were available. NEW interview sheets and stepwise screening tools during the first and second trimester were developed in which 2.5% of pregnant women were identified as requiring social support, respectively. The factors associated with EPDS ≧ 9 were "Women who felt confused/troubled or did not feel anything to be pregnant" (adjusted odds ratio [aOR]: 6.51, 95% confidence interval [CI]: 1.62-26.15), "Maternal mental disorder" (aOR 4.38; CI 1.06-18.10), "Consultation request at first visit" (aOR 3.22; CI 1.09-9.45), and "Women who have difficulty or anxiety about pregnancy during the second trimester" (aOR 3.14; CI 1.29-7.67).

Conclusions

We created the NEW interview sheets and screening tools during the first and the second trimester. Future studies are needed to validate these screening tools.

Association between prenatal exposure to antidepressants and neonatal morbidity: An analysis of real-world data from a nationwide claims database in Japan

BACKGROUND

Depression during pregnancy is relatively undertreated; however, the relationship between prenatal exposure to antidepressants and neonatal outcomes remains controversial.

METHODS

This retrospective cohort study used a Japanese nationwide claims database. Data of 114,359 singletons born between January 2005 and November 2019 were used to evaluate the relationship between prenatal exposure to antidepressants and neonatal morbidity.

RESULTS

Of 2892 mothers with a history of depression before delivery, 352 (12.1%) received prescriptions within three months before delivery (MP3), and 2540 did not (non-MP3). The participants were propensity score matched (PSM) in a ratio of 1:3 using logistic regression (MP3_PSM [n = 351] vs non-MP3_PSM [n = 1052]), and maternal prescriptions of antidepressants within three months before delivery were associated with neonatal morbidity indicators, including admission to the neonatal intensive care unit (NICU) (15.7 vs. 9.1%, odds ratio (OR) 1.9 [95% confidence interval (CI): 1.3-2.6]), poor neonatal adaptation syndrome (6.0 vs 1.0%, OR 6.6 [95% CI: 3.1-14.2]), transient tachycardia (15.7 vs. 6.7%, OR 2.6 [95% CI: 1.8-3.8]), and meconium aspiration syndrome (3.1 vs 0.7%, OR 4.8 [95% CI, 1.9-12.5]). There were no significant differences in the long-term duration of stay at the NICU (>15 days).

LIMITATIONS

Confounding factors may remain even after the propensity matching.

CONCLUSION

Maternal prescription of antidepressants within three months before delivery was associated with increased admission to the NICU. However, the absolute risk of severe neonatal morbidity was low. Therefore, collaborative care for prenatal depression and the neonatal intensive care is warranted.

Applying Rasch methodology to examine and enhance precision of the Edinburgh Postnatal Depression Scale

BACKGROUND

The 10-item Edinburgh Postnatal Depression Scale (EPDS) is a widely used depression measure with acceptable psychometric properties, but it uses ordinal scaling that has limited precision for assessment of outcomes in clinical and research settings. This study aimed to apply Rasch methodology to examine and enhance psychometric properties of the EPDS by developing ordinal-to-interval conversion algorithm.

METHODS

The Partial Credit Rasch model was implemented using a sample of 621 mothers of infants (birth to 2 years old) who completed the EPDS as a part of a larger online survey.

RESULTS

Initial analysis indicated misfit to the Rasch model attributed to local dependency between individual EPDS items. The best model fit was achieved after combining six locally dependent items into three super-items resulting in non-significant item-trait interaction (χ²(49) = 46.61, p < 0.57), strong reliability (PSI = 0.86), unidimensionality and item invariance across personal factors such as age and mothers' education. This permitted generation of ordinal-to-interval conversion algorithms derived from person estimates of the Rasch model.

LIMITATIONS

Ordinal-to-interval conversion cannot be applied for individuals with missing data.

CONCLUSIONS

The EPDS met expectations of the unidimensional Rasch model after internal modifications, and its precision can be enhanced by using ordinal-to-interval conversion tables published in this article without the need to alter the original scale format. Scores derived from these conversion tables should decrease error and improve conformity with statistical assumptions in both clinical and research use of the EPDS, making monitoring of clinical status and outcomes more accurate.

Psychological impacts of the COVID-19 pandemic on one-month postpartum mothers in a metropolitan area of Japan

Background

The coronavirus disease 2019 (COVID-19) pandemic has recently become the most important issue in the world. Very few reports in Japan have examined the impact of the COVID-19 pandemic on peripartum mental health. We examined the status of postpartum mental health before and during COVID-19 pandemic from a consecutive database in a metropolitan area of Japan.

Methods

The subjects were women who had completed a maternity health check-up at a core regional hospital in Yokohama during the period from April 1, 2017, to December 31, 2020. We collected the subjects’ scores for the Edinburgh Postnatal Depression Scale (EPDS) and the Mother-to-Infant Bonding Scale (MIBS) at 1 month postpartum. The subjects were divided into four groups (three Before COVID-19 groups and a During COVID-19 group). MANOVA and post-hoc tests were used to determine mental health changes in the postpartum period among the four groups.

Results

The Before and During COVID-19 groups contained 2844 and 1095 mothers, respectively. There were no significant difference in the total scores of the EPDS and MIBS among the four groups. However, the EPDS items related to anxiety factors were significantly higher and the EPDS items related to anhedonia and depression factors (excluding thoughts of self-harm) were significantly lower in the During COVID-19 group.

Conclusion

The EPDS scores changed in connection with the COVID-19 pandemic. Anxiety, which represent hypervigilance, was significantly higher and anhedonia and depression were significantly lower in the During COVID-19 group. Our results may reflect COVID-19-related health concerns and a lack of social support caused by the COVID-19 pandemic.

Edinburgh Postnatal Depression Scale scores at 2-week post-partum may reflect those at 4-week post-partum: A single-center retrospective observational study

AIM

Most Japanese institutions screen for post-partum depression (PPD) using the Edinburgh Postnatal Depression Scale (EPDS) at outpatient visits conducted at 2- and 4-week post-partum, but there are no published data on the usefulness of EPDS scores 2-week post-partum. In the present study, relationships between 2-week post-partum EPDS scores and 4-week post-partum EPDS scores were investigated to determine whether 2-week scores may facilitate early intervention in high-risk mothers.

METHODS

A retrospective analysis of 451 deliveries from 2017 to 2019 was conducted at a single institution. EPDS scores were obtained using the Japanese EPDS 2- and 4-week post-partum, in conjunction with other perinatal data from medical records.

RESULTS

In total, 334 of 451 mothers (74.1%) completed the EPDS at both 2- and 4-week post-partum and were included in the analysis. Of 48 who had higher scores 2-week post-partum, 21 (43.8%) continued to be at high risk of PPD. Of 284 who had lower scores 2-week post-partum, 9 (3.2%) transitioned to scores indicating high risk. Women considered high-risk 4-week post-partum tended to have exhibited higher scores 2-week post-partum. Women who had experienced more deliveries tended to exhibit lower scores, and psychiatric illness was strongly associated with higher EPDS scores (odds ratio 11.2, 95% confidence interval 3.7-33.8, P < 0.01).

CONCLUSION

Two-week EPDS scores closely reflected 4-week scores, and may facilitate early intervention to prevent PPD. Primiparous mothers and those with a history of psychiatric illness should be followed-up closely.
