Effects of an early intervention on maternal post-traumatic stress symptoms and the quality of mother–infant interaction: The case of preterm birth

Early psychosocial parent-infant interventions and parent-infant relationships after preterm birth-a scoping review

Objective

Early psychosocial interventions for preterm infants and their parents are diverse. This study aimed to structure the knowledge on psychosocial parent-infant interventions and to identify gaps in the intervention studies.

Methods

We included studies on early (during first year of life) psychosocial parent-infant interventions with parent-infant relationship outcomes after preterm birth (< 37 weeks). We excluded studies that did not focus on preterm infants, failed to indicate the studied intervention and outcomes, were not written in English, were not controlled or peer-reviewed studies, or did not provide essential information for eligibility. The search included studies published between January 2000 and March 2024 in PubMed and PsycINFO. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed in reporting. Psychosocial parent-infant intervention studies were classified adapting the International Classification of Health Interventions (ICHI) and the Template for Intervention Description and Replication (TIDieR).

Results

The included 22 studies reported data from 18 different interventions with preterm infants (< 37 weeks). Studies excluded preterm infants with health risks (19/22, 86%), with very low gestational age and/or birth weight (7/22, 32%), and/or mothers with psychosocial risks (14/22, 64%). Of the 18 interventions, 12 (67%) were classified as counseling, 3 (17%) as emotional support, 2 (11%) as psychotherapeutic, and 1 (6%) as educational. The parent-child relationship was assessed using 30 different methods and varying time points up to 18 months of age. Most studies (17/22, 77%) reported positive changes in the parent-child relationship favoring the intervention group.

Conclusion

We identified four types of interventions to influence parenting behavior; the most used was counseling. All four intervention types showed positive effects on parent-infant relationships, although the preterm populations studied were selective, the effects were evaluated using different methods, and the follow-up periods were short. These findings indicate a need for studies with standardized methods, longer follow-up, and less-restricted preterm populations to develop guidelines for all families with preterm infants.

Effectiveness and family experiences of interventions promoting partnerships between families and pediatric and neonatal intensive care units: a mixed methods systematic review

OBJECTIVE

The objective of this mixed methods review was to examine the effectiveness and family experiences of interventions promoting partnerships between families and the multidisciplinary health care team in pediatric and neonatal intensive care units.

INTRODUCTION

Hospitalization of infants and children in neonatal intensive care units and pediatric intensive care units has a significant effect on their families, including increased stress, anxiety, and depression. Available evidence syntheses focused on specific family-centered care, but not on partnership, which is another aspect that may improve families' outcomes and experiences.

INCLUSION CRITERIA

This review considered studies that focused on effectiveness or family experiences of interventions by health professionals in partnership with families of infants or children hospitalized in an intensive care unit. For the quantitative component of the review, the type of intervention was a partnership between the health care team and the family, and focused on outcomes of stress, anxiety, depression, quality of life, attachment, or satisfaction with family-centered care. For the qualitative component, the phenomenon of interest was family experiences of interventions that included collaboration and partnering with the health care team in the pediatric or neonatal intensive care unit. Quantitative, qualitative, and mixed methods studies, published from 2000 to August 2022 in English or French, were eligible for inclusion.

METHODS

The JBI methodology for convergent segregated mixed methods systematic reviews was followed using the standardized JBI critical appraisal and data extraction tools. Ten databases were searched in December 2019 and again in August 2022. Study selection, critical appraisal, and data extraction were performed by 2 reviewers independently. Findings of quantitative studies were statistically pooled through meta-analysis and those that could not be pooled were reported narratively. Qualitative studies were pooled through meta-synthesis.

RESULTS

This review included 6 qualitative and 42 quantitative studies. The methodological quality varied, and all studies were included regardless of methodological quality. Meta-analyses showed improvements in anxiety, satisfaction with family-centered care, and stress, yet no conclusive effects in attachment and depression. These results should be interpreted with caution due to high heterogeneity. Qualitative analysis resulted in 2 synthesized findings: "Interventions that incorporate partnerships between families and the health care team can improve the family's experience and capacity to care for the child" and "Having a child in intensive care can be an experience of significant impact for families." Integration of quantitative and qualitative evidence revealed some congruence between findings; however, the paucity of qualitative evidence minimized the depth of this integration.

CONCLUSIONS

Partnership interventions can have a positive impact on parents of children in intensive care units, with improvements reported in stress, anxiety, and satisfaction with family-centered care.

Psychological interventions to pregnancy-related complications in patients with post-traumatic stress disorder: a scoping review

OBJECTIVE

This scoping review sought to investigate the association between pregnancy-related complications and post-traumatic stress disorder (PTSD) among postpartum women, then summarize effective psychological interventions for pregnancy-related PTSD or sub-PTSD.

METHOD

Publications in English and Chinese were searched in PubMed, Embase, Cochrane, ISI Web of Science, China National Knowledge Infrastructure (CNKI), and WanFang databases using the subject headings of "Stress Disorders, Post-Traumatic", "Pregnant Women", and "psychotherapy". To ensure that as many relevant studies are incorporated as possible, free terms such as prenatal, postnatal, perinatal and gestation were also used. Intervention studies and related cases published by July 1st, 2023, were also searched.

RESULTS

Twenty-one articles (including 3,901 mothers) were included in this review. Evidence showed that typical psychological interventions exhibited great effect, and family support programs, peer support, online yoga, and music therapy were also effective in reducing risk and improving the psychological well-being of the studied population.

CONCLUSION

Fetal abnormalities, miscarriage, premature birth, infants with low birth weights, hypertension, pre-eclampsia, HELLP syndrome, and hyperemesis gravidarum are associated with an increased risk of PTSD. Moreover, high-risk pregnant women may benefit from psychological interventions such as cognitive behavioral therapy (CBT). It may also be feasible and well-accepted for music therapy and exposure therapy to lessen the intensity of PTSD in mothers.

Preventing posttraumatic stress disorder following childbirth: a systematic review and meta-analysis

OBJECTIVE

Women can develop posttraumatic stress disorder in response to experienced or perceived traumatic, often medically complicated, childbirth; the prevalence of these events remains high in the United States. Currently, no recommended treatment exists in routine care to prevent or mitigate maternal childbirth-related posttraumatic stress disorder. We conducted a systematic review and meta-analysis of clinical trials that evaluated any therapy to prevent or treat childbirth-related posttraumatic stress disorder.

DATA SOURCES

PsycInfo, PsycArticles, PubMed (MEDLINE), ClinicalTrials.gov, CINAHL, ProQuest, Sociological Abstracts, Google Scholar, Embase, Web of Science, ScienceDirect, Scopus, and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched for eligible trials published through September 2023.

STUDY ELIGIBILITY CRITERIA

Trials were included if they were interventional, if they evaluated any therapy for childbirth-related posttraumatic stress disorder for the indication of symptoms or before posttraumatic stress disorder onset, and if they were written in English.

METHODS

Independent coders extracted the sample characteristics and intervention information of the eligible studies and evaluated the trials using the Downs and Black's quality checklist and Cochrane's method for risk of bias evaluation. Meta-analysis was conducted to evaluate pooled effect sizes of secondary and tertiary prevention trials.

RESULTS

A total of 41 studies (32 randomized controlled trials, 9 nonrandomized trials) were reviewed. They evaluated brief psychological therapies including debriefing, trauma-focused therapies (including cognitive behavioral therapy and expressive writing), memory consolidation and reconsolidation blockage, mother-infant-focused therapies, and educational interventions. The trials targeted secondary preventions aimed at buffering childbirth-related posttraumatic stress disorder usually after traumatic childbirth (n=24), tertiary preventions among women with probable childbirth-related posttraumatic stress disorder (n=14), and primary prevention during pregnancy (n=3). A meta-analysis of the combined randomized secondary preventions showed moderate effects in reducing childbirth-related posttraumatic stress disorder symptoms when compared with usual treatment (standardized mean difference, -0.67; 95% confidence interval, -0.92 to -0.42). Single-session therapy within 96 hours of birth was helpful (standardized mean difference, -0.55). Brief, structured, trauma-focused therapies and semi-structured, midwife-led, dialogue-based psychological counseling showed the largest effects (standardized mean difference, -0.95 and -0.91, respectively). Other treatment approaches (eg, the Tetris game, mindfulness, mother-infant-focused treatment) warrant more research. Tertiary preventions produced smaller effects than secondary prevention but are potentially clinically meaningful (standardized mean difference, -0.37; -0.60 to -0.14). Antepartum educational approaches may help, but insufficient empirical evidence exists.

CONCLUSION

Brief trauma-focused and non-trauma-focused psychological therapies delivered early in the period following traumatic childbirth offer a critical and feasible opportunity to buffer the symptoms of childbirth-related posttraumatic stress disorder. Future research that integrates diagnostic and biological measures can inform treatment use and the mechanisms at work.

[Post-hospital support for families: current situation and outlook]

After neonatal hospitalization, our healthcare system offers multidisciplinary care for premature babies and their families during the first years of life. However, there are disparities and gaps, particularly in the case of medium prematurity. Maternal and child protection, a major player in early prevention and family follow-up, is a partner likely to be able to deploy post-hospital support perspectives in favor of child development and parenting support.

Joint observation in NICU (JOIN): A randomized controlled trial testing an early, one-session intervention during preterm care to improve perceived maternal self-efficacy and other mental health outcomes

BACKGROUND

Parents of preterm infants in the Neonatal Intensive Care Unit (NICU) environment may experience psychological distress, decreased perceived self-efficacy, and/or difficulties in establishing an adaptive parent-infant relationship. Early developmental care interventions to support the parental role and infant development are essential and their impact can be assessed by an improvement of parental self-efficacy perception. The aims were to assess the effects of an early intervention provided in the NICU (the Joint Observation) on maternal perceived self-efficacy compared to controls (primary outcome) and to compare maternal mental health measures (perceived stress, anxiety, and depression), perception of the parent-infant relationship, and maternal responsiveness (secondary outcomes).

METHODS

This study was a monocentric randomized controlled trial registered in clinicatrials.gov (NCT02736136), which aimed at testing a behavioural intervention compared with treatment-as-usual. Mothers of preterm neonates born 28 to 32 6/7 weeks gestation were randomly allocated to either the intervention or the control groups. Outcome measures consisted of self-report questionnaires completed by the mothers at 1 and 6 months after enrollment and assessing perceived self-efficacy, mental health, perception of the parent-infant relationship and responsiveness, as well as satisfaction with the intervention.

RESULTS

No statistically significant group effects were observed for perceived maternal self-efficacy or the secondary outcomes. Over time, perceived maternal self-efficacy increased for mothers in both groups, while anxiety and depression symptoms decreased. High satisfaction with the intervention was reported.

CONCLUSIONS

The joint observation was not associated with improved perceived maternal self-efficacy or other mental health outcomes, but may constitute an additional supportive measure offered to parents in a vulnerable situation during the NICU stay.

Psycho-emotional intervention with parents of very preterm babies during the first year: A single-arm pilot study

Studies of intervention programs that aim to improve the emotional state of parents of children admitted to the neonatal intensive care units (NICU) are scarce in Spain. The aims of this single-arm pilot study are to get to know the emotional profile of parents of high-risk preterm newborns, and to explore parents' patterns of emotional well-being before and after a psychological program called the Parental Empowerment Program, to increase parental readiness levels. The sample was made up of 100 parents (50 couples) who participated in the program. Measurements were taken of post-traumatic stress, depression, and resilience at 1 month and 12 months. Repeated measurements and dyadic data analyses were performed. One month after the birth of the baby and prior to the start of the program, mothers show more symptoms of stress and depression than fathers. After the intervention, both parents experienced improvements in their mood levels. The evidence obtained seems to show that high resilience levels and low post-traumatic stress symptoms are associated with reduced depression levels after implementing the program. However, the heterogeneity of the responses obtained, the observed associations between stress, resilience, and maternal depression, along with the reciprocal influence between maternal and paternal depression 1 year after the intervention, highlight the need for a more in-depth exploration of the interplay between risk and protective factors in this population. Despite the identified potential threats to validity, further work in this direction is recommended, including the implementation of clinical trials to demonstrate intervention efficacy. The adaptation of the parents' mutual emotional adjustment at each stage would allow them to participate more actively in the baby's care.

A Systematic Review of Interventions for Prevention and Treatment of Post-Traumatic Stress Disorder Following Childbirth

Objective

Postpartum women can develop post-traumatic stress disorder (PTSD) in response to complicated, traumatic childbirth; prevalence of these events remains high in the U.S. Currently, there is no recommended treatment approach in routine peripartum care for preventing maternal childbirth-related PTSD (CB-PTSD) and lessening its severity. Here, we provide a systematic review of available clinical trials testing interventions for the prevention and indication of CB-PTSD.

Data Sources

We conducted a systematic review of PsycInfo, PsycArticles, PubMed (MEDLINE), ClinicalTrials.gov, CINAHL, ProQuest, Sociological Abstracts, Google Scholar, Embase, Web of Science, ScienceDirect, and Scopus through December 2022 to identify clinical trials involving CB-PTSD prevention and treatment.

Study Eligibility Criteria

Trials were included if they were interventional, evaluated CB-PTSD preventive strategies or treatments, and reported outcomes assessing CB-PTSD symptoms. Duplicate studies, case reports, protocols, active clinical trials, and studies of CB-PTSD following stillbirth were excluded.

Study Appraisal and Synthesis Methods

Two independent coders evaluated trials using a modified Downs and Black methodological quality assessment checklist. Sample characteristics and related intervention information were extracted via an Excel-based form.

Results

A total of 33 studies, including 25 randomized controlled trials (RCTs) and 8 non-RCTs, were included. Trial quality ranged from Poor to Excellent. Trials tested psychological therapies most often delivered as secondary prevention against CB-PTSD onset (n=21); some examined primary (n=3) and tertiary (n=9) therapies. Positive treatment effects were found for early interventions employing conventional trauma-focused therapies, psychological counseling, and mother-infant dyadic focused strategies. Therapies' utility to aid women with severe acute traumatic stress symptoms or reduce incidence of CB-PTSD diagnosis is unclear, as is whether they are effective as tertiary intervention. Educational birth plan-focused interventions during pregnancy may improve maternal health outcomes, but studies remain scarce.

Conclusions

An array of early psychological therapies delivered in response to traumatic childbirth, rather than universally, in the first postpartum days and weeks, may potentially buffer CB-PTSD development. Rather than one treatment being suitable for all, effective therapy should consider individual-specific factors. As additional RCTs generate critical information and guide recommendations for first-line preventive treatments for CB-PTSD, the psychiatric consequences associated with traumatic childbirth could be lessened.

Prevalence of postpartum post-traumatic stress disorder and its determinants in Mainland China: A systematic review and meta-analysis

BACKGROUND

The prevalence and risk factors of postpartum posttraumatic stress disorder reported by population-based studies have significantly varied and the data are all collected from regional populations in Mainland China.

AIMS

To utilize published data to estimate the overall prevalence of postpartum posttraumatic stress disorder and its determinants in Mainland China.

METHODS

Comprehensively electronic searches were performed across six English databases and three Chinese databases. Random effects of the meta-analysis were performed to evaluate the pooled prevalence of postpartum posttraumatic stress disorder. Meta-regression was performed with the variable of study design, sample size, setting, measures, region, time points, and publication year.

RESULTS

Totaling of nineteen studies was included, with a sample size of 13,231 postpartum women. The pooled prevalence of postpartum posttraumatic stress disorder was 11.2 % in Mainland China, with a higher prevalence at the timepoint within 1 month postpartum (18.1 %). Significant publication bias and heterogeneity were found (I² = 97.1 %). Sample size and measurements were conditional on the prevalence of postpartum posttraumatic stress disorder. Postpartum depressive symptoms, sleep problems, cesarean section, and low levels of social support were the major risk factors for postpartum posttraumatic stress disorder. While being the one child in the family was the protective factor.

CONCLUSION

An increasing prevalence of posttraumatic stress disorder within one month postpartum significantly arises awareness to provide screening and more mental health services during this period. Screening programs for postpartum posttraumatic stress disorder are still needed in Mainland China.

Symptoms of post-traumatic stress disorder in parents of preterm newborns: A systematic review of interventions and prevention strategies

Background

Preterm birth and subsequent NICU admission can be a traumatic experience for parents who may subsequently develop post-traumatic stress (PTS) disorder (PTSD). Given that developmental issues are common among children of parents with PTSD, interventions for prevention and treatment are essential.

Objective

To assess the most effective non-pharmacological interventions to prevent and/or treat PTS symptoms in parents of preterm newborns.

Methods

Systematic review performed in accordance with the PRISMA statements. Eligible articles in English language were searched in MEDLINE, Scopus, and ISI Web of Science databases using the following medical subject headings and terms: “stress disorder, post-traumatic,” “parents,” “mothers,” “fathers,” “infant, newborn,” “intensive care units, neonatal,” and “premature birth.” The terms “preterm birth” and “preterm delivery” were also used. Unpublished data were searched in ClinicalTrials.gov website. All intervention studies published until September 9th, 2022 and including parents of newborns with gestational age at birth (GAb) &lt;37 weeks which underwent ≥1 non-pharmaceutical interventions for prevention and/or treatment of PTS symptoms related to preterm birth were included. Subgroup analyses were conducted by type of intervention. The quality assessment was performed according to the criteria from the RoB-2 and the “NIH Quality Assessment Tool for Before-After studies.”

Results

Sixteen thousand six hundred twenty-eight records were identified; finally, 15 articles (1,009 mothers, 44 fathers of infants with GAb ≤ 366/7 weeks) were included for review. A good standard of NICU care (effective as sole intervention: 2/3 studies) and education about PTSD (effective in association with other interventions: 7/8 studies) could be offered to all parents of preterm newborns. The 6-session Treatment Manual is a complex intervention which revealed itself to be effective in one study with low risk of bias. However, the effectiveness of interventions still remains to be definitively established. Interventions could start within 4 weeks after birth and last 2–4 weeks.

Conclusion

There is a wide range of interventions targeting PTS symptoms after preterm birth. However, further studies of good quality are needed to better define the effectiveness of each intervention.

Parenting Style Interventions in Parents of Preterm and High-Risk Infants: Controversies, Cost, and Future Directions

This review highlights the current state of evidence on interventions whose primary purpose is to change parenting style in parents of preterm, and other-high risk, infants. To date, interventions for parents of preterm infants are heterogeneous with variability in intervention timing, measured outcomes, program components, and cost. Most interventions target parental responsivity/sensitivity. Most reported outcomes are short-term, measured at age less than 2 years. The few studies that report later child outcomes in prekindergarten/school-aged children are encouraging, overall indicating improved cognition and behavior in the children of parents who received a parenting style intervention.

Acceptability and feasibility of a digital educational intervention designed to improve the psychological well-being of parents with a preterm infant at the neonatal intensive care unit: A pilot project

BACKGROUND

Families experience psychological distress when their preterm infant is in the Neonatal Intensive Care Unit. A tailored educational intervention may be beneficial for their psychological well-being. Unfortunately, existing websites have moderate to low information quality and there is no educational website for French-speaking parents.

AIM

To measure the acceptability and feasibility of a digital educational intervention designed to improve the psychological well-being of parents with a preterm infant, as well as the acceptability and feasibility of the study methods used.

METHODS

A pilot randomized controlled trial was conducted. Participants were randomized to have access to either an educational website or information pamphlet. They were invited to complete an online questionnaire about stress and depressive symptoms 2 and 4 weeks after recruitment. An online questionnaire regarding the acceptability of the intervention and the data collection process was completed 5 weeks after recruitment.

RESULTS

Twenty parents participated. All participants with access to the website considered it was acceptable in terms of the appropriateness, convenience, and efficiency to meet their informational needs. 85 % of participants assigned to the website viewed it 1 to 3 times per day during the data collection period and 69.4 % consulted the website for 5 to 20 min each time. The data collection process was acceptable for 85 % to 95 % of participants.

DISCUSSION

The educational website was an acceptable and feasible intervention and the data collection process used was acceptable according to participants.

Risk factors and preventive strategies for post-traumatic stress disorder in neonatal intensive care unit

BACKGROUND

Preterm birth and admission to the neonatal intensive care unit (NICU) could induce post-traumatic stress disorder (PTSD). PTSD is an important factor to focus on, as it is associated with parental mental health difficulties and with changes in caregiving quality such as increased intrusiveness, reduced sensitivity, and increased attachment insecurity for the child.

AIMS

We aimed to study the main risk factors, in the early life of newborns, and preventive measures for PTSD in parents of neonates hospitalized in the NICU.

METHODS

We included parents of preterm newborns, consecutively admitted to the NICU of the University La Sapienza of Rome. The presence of PTSD following preterm birth and NICU admission was assessed using the Clinician-administered PTSD scale (CAPS) at enrollment and at 28-30 days following NICU admission or the moment of discharge. We also evaluated the Family Environment Scale which measures the social environment of all types of families; the Parental Stressor Scale which measures parental anxiety and stress; the Spielberger State-Trait Anxiety Inventory consisting of two parts measuring the State (response to present situation) and Trait (pre-disposition to be anxious) anxieties separately, and the Beck Depression Inventory Second Edition assessing depressive symptoms.

RESULTS

We found, in a multivariate analysis, that the gestational age of newborns admitted to NICU significantly (β = 2.678; p = 0.040) influences the occurrence of PTSD. We found that the cases showed significantly (β = 2.443; p = 0.020) more pathological Parental Stressor Scale sights and sounds scores compared to controls. The early Kangaroo-Care (KC) significantly (β = -2.619; p = 0.015) reduces the occurrence of PTSD.

CONCLUSION

Post-traumatic stress disorder in parents of preterm newborns is a pathological condition that should be properly managed, in the very first days after birth. The NICU environment represents a main risk factor for PTSD, whereas KC has been demonstrated to have a protective role in the occurrence of PTSD.

Supportive psychological therapy can effectively treat post-stroke post-traumatic stress disorder at the early stage

Post-traumatic stress disorder (PTSD) can develop after stroke attacks, and its rate ranges from 4 to 37% in the stroke population. Suffering from PTSD not only decreases stroke patient’s quality of life, but also relates to their non-adherence of treatment. Since strokes often recur and progress, long-term medical management is especially important. However, previous studies generally focused on the epidemiological characteristics of post-stroke PTSD, while there are literally no studies on the psychological intervention. In our study, 170 patients with a first-ever stroke during the acute phase were recruited. They were randomized into Psycho-therapy group 1 and Control group 1, and were administered with preventive intervention for PTSD or routine health education, respectively. At 2-month follow-up, PTSD symptoms were evaluated. Participants who were diagnosed with post-stroke PTSD were further randomized into Psycho-therapy group 2 and Control group 2, and received supportive therapy or routine health counseling, respectively. At 6-month follow-up (1°month after the therapy was completed), PTSD symptoms were re-evaluated. Our results showed that at 2-month, the PTSD incidence in our series was 11.69%, and the severity of stroke was the only risk factor for PTSD development. The preventive intervention was not superior to routine health education for PTSD prevention. At 6-month, results indicated the supportive therapy did have a fine effect in ameliorating symptoms for diagnosed PTSD patients, superior to routine health counseling. Thus, our study was the first to provide evidence that the supportive therapy was effective in treating post-stroke PTSD early after its diagnosis. This clinical trial was preregistered on www.chictr.org.cn (ChiCTR2100048411).

Effective stress intervention programs for parents of premature children: A systematic review

The birth of a child alters family dynamics and can be stressful for parents, especially in the case of prematurity. This article carried out a systematic review on interventions in parents to reduce the stress experienced by the birth of a premature infant. The aims were to describe and classify the different interventions and to have an overview of their effectiveness. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guide and the PICO model. For searching the bibliography, we used Web of Science, Science Direct, PubMed and PsycINFO databases. From a total of 450 articles identified, this review finally included 46 studies with empirical evidence. The articles clustered into different types of interventions, such as psychoeducational and parental or maternal support programs, relaxation techniques, expressive writing, art therapy, music therapy and interventions related to interaction and tactile stimulation. There is a wide range of effectiveness in reducing parental stress to a greater or lesser degree. There is a great heterogeneity of interventions. Despite that, they all have a parental educational component that needs to be studied in greater depth.

Mothers' experiences of a new early collaborative intervention, the EACI, in the neonatal period: A qualitative study

AIM

To explore mothers' experiences of the EArly Collaborative Intervention.

BACKGROUND

Preterm birth puts a considerable emotional and psychological burden on parents and families. Parents to moderate and late premature infants have shorter stays at the neonatal intensive care unit and have described a need for support. The EArly Collaborative Intervention was developed to support parents with preterm infants born between gestational Weeks 30 to 36. In this study, mothers' experiences of the new intervention were explored.

DESIGN

A qualitative design guided by a reflexive thematic analysis according to Braun and Clarke. Interviews were individually performed with 23 mothers experienced with the EArly Collaborative Intervention. Data were identified, analysed and reported using reflexive thematic analysis. The COREQ checklist was used preparing the manuscript.

RESULTS

Two main overarching themes were constructed. The first theme, 'mothers' feelings evoked from the EArly Collaborative Intervention' describes the emotions raised by the intervention and how the intervention affected their parental role. Their awareness of the preterm baby's behaviour increased, and the intervention helped the parents to communicate around their baby's needs. The second theme, 'based on the preterm baby's behavior', describes experiences of the provision and the learning process about their preterm baby's needs and communication. The intervention was experienced as helpful both immediately and for future interaction with the baby.

CONCLUSIONS

Mothers found the intervention to be supportive and encouraging. They came to look upon their baby as an individual, and the new knowledge on how to care and interact with their baby affected both their own and their baby's well-being. Furthermore, the intervention felt strengthening for their relationship with the other parent.

RELEVANCE TO CLINICAL PRACTICE

The EArly Collaborative Intervention can support parents' abilities as well as their relation to their baby and may thereby contribute to infant development, cognition and well-being.

Attachment- and Relationship-Based Interventions during NICU Hospitalization for Families with Preterm/Low-Birth Weight Infants: A Systematic Review of RCT Data

This study conducts a systematic review and meta-analysis of the randomized-controlled clinical trials (RCTs) of attachment- and relationship-based interventions in the NICU. A systematic search of the PubMed, MEDLINE, Embase (OVID), PsycINFO, and CINAHL databases and the Cochrane Database of Systematic Reviews was conducted in February 2021. Of the 32,904 studies examined, 15 were identified as relevant, and 10 RCTs were eligible for meta-analysis. Cochrane’s risk of bias tool was used to assess the quality of the trial reporting. Interventions were categorized as (1) parent–infant interactions, (2) parent education, and/or (3) support through qualitative synthesis. The attachment- or relationship-based intervention was effective in relieving maternal traumatic stress, maternal depression, infant weight growth, and infant development. Subgroup analyses suggested that interventions significantly improved sub-domains of mothers’ and children’s interactive behavior. Tailored, staged interventions may contribute to better health outcomes in preterm infants and their families.

Parental Reflective Functioning as a Moderator of the Link Between Prematurity and Parental Stress

We examined group differences between parents, both mothers and fathers, of premature and full-term infants to determine whether they differed in their reports of subjective parenting stress and in their level of parental reflective functioning (PRF). We also tested whether each parent's reflective functioning moderated the links between birth status (prematurity vs. full-term) and parenting stress. A sample of 73 cohabiting, heterosexual Israeli families with a premature (28-36th week gestational age, N = 34) or full-term infant (37th week and above gestational age, N = 39) participated, comprising the two parents' groups. Infants' age averaged 7.07 months (SD = 1.28). Each parent completed the Parent Stress Inventory (PSI) individually to determine his/her subjective personal and childrearing stress levels. The Parent Development Interview (PDI-R2-S) was used to obtain each parent's PRF (self and child/relation-focused) level. Findings showed that the premature and full-term parents did not differ in their PSI scores or PRF levels. However, mothers' self-focused PRF moderated the link between prematurity and personal parenting stress, whereas fathers' self-focused PRF moderated the link between prematurity and childrearing parenting stress. Furthermore, fathers' and mothers' PRF operated differently in the premature and full-term parents' groups. The findings highlight the importance of mothers' and fathers' PRF in predicting parents' subjective stress in general and particularly in the case of infant prematurity. We discuss these findings and their relevance for preventive and therapeutic perinatal interventions.

[Early mother-infant care, definition and effectiveness: A review of the literature]

OBJECTIVE

Professionals agree on the need for early joint mother-baby care, but its effectiveness remains poorly studied. The aim of our work is to propose a review of the literature on this subject.

METHODS

We included randomized or non-randomized controlled clinical trials of interventions targeting the mother-baby dyad which can begin during pregnancy or during the first three years of life.

RESULTS

Forty-one studies met the inclusion criteria and focused on mother-baby psychotherapy, educational or guidance programs, care for premature infants, infant massage, and home visits. The results show an improvement of the quality of the interactions whatever the type of approach, but according to different indications or modalities. The heterogeneity of intervention methods and indications make the comparison of results almost impossible.

CONCLUSION

This work highlights the lack of consensus on mother-child care methods, both for their indications and their effectiveness. The isolated evaluation of interactions is an insufficient criterion for judging the effectiveness of care. Finally, whatever the theoretical models, the interventions must take into account the environment of the child.

Effects of early intervention on parenting stress after preterm birth: A meta-analysis

BACKGROUND

Preterm infants have a higher risk of development disorders. Prematurity can be considered a source of stress, in both children and their parents, due to the high number of interventions that they require. Early intervention (EI) programmes have shown to have a positive influence on the neurodevelopment of children with neurological risk. On the other hand, parenting stress has a negative influence on the development of any child. This systematic review aimed to identify the effect of EI programmes on decreasing parenting stress suffered by parents of preterm babies.

METHODS

Systematic review and meta-analysis of experimental studies in accordance with the PRISMA declaration guidelines were applied in this work.

RESULTS

Fifteen randomized clinical trials were included whose methodological quality was assessed using the PEDro scale. Stress data extraction was meta-analysed using the inverse variance method in a random effects model. Statistical heterogeneity was assessed with the I² heterogeneity statistic. The domains most commonly reported in the trials were the childcare-related stress (Child Domain), personal discomfort (Parent Domain) and computation of both (Total Stress). The results showed significant (P < 0,05) and clinically relevant differences in favour of the EI programme group at 18 months and 5 years.

CONCLUSIONS

This review found moderate to strong evidence of the impact of EI programmes on the reduction of parenting stress in parents of preterm babies. These findings offer useful insights regarding the delivery of current support and the development of future family interventions. Finally, recommendations are provided for future intervention evaluation studies in this area.

A home-based, post-discharge early intervention program promotes motor development and physical growth in the early preterm infants: a prospective, randomized controlled trial

BACKGROUND

The implementation of early intervention (EI) in medical settings is time-consuming and resource-intensive, which limits its extensive use. In 2018, the Chinese Eugenics Association developed a home-based, post-discharge EI program. This study aims at evaluating the impact of this EI program on neurodevelopment and physical growth of early preterm infants.

METHODS

This study was a prospective, partially blinded, randomized controlled trial (RCT), followed by an open phase. A total of 73 infants born at 28+ 0 ~ 31+ 6 weeks' gestation who were admitted to the Children's Hospital of Chongqing Medical University between December 1, 2019, and June 31, 2020, were enrolled. Another 33 infants were retrospectively recruited as the reference group. Thirty-seven infants randomized in the first early intervention, then standard care (EI-SC) group performed a 30-day EI during RCT period, while 36 infants allocated to SC-EI group were given EI in the following open phase. The test of infant motor performance (TIMP), development quotient (DQ), and anthropometric measures (length, weight, head circumference) were measured at the baseline (T0), termination of the RCT (T1), and termination of the open phase (T2). Repeated measures analysis was performed for comparison among groups.

RESULTS

From T0 to T1, both groups had significant improvements in all outcome measures (all p < 0.001). A 30-day EI program was more effective in improving TIMP than standard care (from 53.12 ± 8.79 to 83.50 ± 11.85 in EI-SC group vs from 50.52 ± 8.64 to 75.97 ± 13.44 in SC-EI group, F = 4.232, p = 0.044). EI-SC group also had greater improvements in length, weight, and head circumference than SC-EI group (all p < 0.05). From T0 to T2, there was no significant difference regarding the improvements in all outcomes between the groups (all p > 0.05). At the endpoint of T2, the EI-SC and SC-EI group had similar TIMP and anthropometric measures, but much higher than the reference group (all p < 0.05).

CONCLUSIONS

These findings demonstrated that a home-based, post-discharge EI program in this study was a practical approach to promote motor development and physical growth in early preterm infants.

Preventing the onset of post traumatic stress disorder

Post-traumatic stress disorder (PTSD) is a common mental health condition that requires exposure to a traumatic event. This provides unique opportunities for prevention that are not available for other disorders. The aim of this review was to undertake a systematic review and evaluation of randomized controlled trials (RCTs) of interventions designed to prevent PTSD in adults. Searches involving Cochrane, Embase, Medline, PsycINFO, PILOTS and Pubmed databases were undertaken to identify RCTs of pre-incident preparedness and post-incident interventions until May 2019. Six pre-incident and 69 post-incident trials were identified that could be included in meta-analyses. The overall quality of the evidence was low. There was emerging evidence that some interventions may be helpful but an absence of evidence for any intervention that can be strongly recommended for universal, selected or indicated prevention before or within the first three months of a traumatic event. The strongest results were found for cognitive-behavioural therapy with a trauma focus (CBT-T) in individuals with a diagnosis of acute stress disorder which supports calls to detect and treat individuals with significant symptoms rather than providing blanket preventative interventions. Further research is required to optimally configure existing interventions with some evidence of effect and to develop novel interventions to address this major public health issue.

Sleep patterns, problems, and ecology in young children born preterm and full-term and their mothers

BACKGROUND

Previous studies of sleep patterns and problems in preterm infants compared to full-term infants have yielded mixed results, with little known about sleep ecology. The aims of this study were to compare sleep patterns, sleep problems, and sleep ecology across developmental stages (birth to 36 months) in preterm (3 or more weeks early) infants and toddlers to those born full-term, in addition to their mothers' sleep.

METHODS

Mothers of 834 young children in Brazil (ages 0-35.9 months), half preterm and half full-term (matched for sex and chronological age), completed the Brief Infant Sleep Questionnaire and the Pittsburgh Sleep Quality Index.

RESULTS

Across the entire sample, preterm and full-term infants were similar for most sleep parameters, including sleep onset latency, number and duration of night awakenings, and sleep duration, as well as sleep ecology parameters, including falling asleep independently and sleep location. However, preterm infants were more likely to be held to initiate sleep, given a bottle to resume sleep after waking, and less likely to be breastfed to resume sleep after waking. Mothers of preterm infants, however, were more likely to report a parent-perceived sleep problem, although maternal-perceived confidence in managing child sleep and bedtime difficulty were similar. Finally, maternal sleep parameters were similar between groups.

CONCLUSIONS

Overall, these results indicate that sleep patterns, sleep problems, and sleep ecology among preterm infants and toddlers and their mothers are largely similar to those of full-term infants and toddlers and their mothers, even within the first few months.

Promoting infant mental health in the neonatal intensive care unit (NICU): A review of nurturing factors and interventions for NICU infant-parent relationships

Premature and medically vulnerable infants experience early and sometimes prolonged separation from their parents, intrusive and unnatural environments, painful and distressing procedures, difficulties with physiological regulation, increased biological and neurological vulnerabilities, and grow up to have higher rates of neurocognitive and psychosocial difficulties. Parents of infants born prematurely or with medical vulnerabilities, in turn, experience significant distress and are a psychiatrically vulnerable population, with very high rates of depression, anxiety, and posttraumatic stress disorder. The combination of these factors cause significant challenges for some of these infants and parents in developing an early optimal relationship and connection. Given the critical importance of early relationships with main caregivers for infant mental health and long-term developmental outcomes, we review various targets of intervention to promote healthy infant and parent mental health and bonding thereby facilitating an optimal infant-parent relationship in the NICU population.

A systematic review of clinical effectiveness of psychological interventions to reduce post traumatic stress symptoms following childbirth and a meta-synthesis of facilitators and barriers to uptake of psychological care

AIM

To review the literature on psychological interventions for post-traumatic stress following childbirth (PTSDFC) and determine clinical effectiveness. To synthesise the qualitative literature on the facilitators and barriers to uptake of care for PTSDFC.

BACKGROUND

The context of childbirth trauma differs from that of other events perceived as traumatic. Current guidance on treatment for PTSDFC requires further clarification.

METHOD

Web of Knowledge, CINAHL, MEDLINE, PSYCINFO, the Cochrane Central Register of Controlled Trials (CENTRAL), Open Grey, UKCTG, and the ISRCTN were consulted to include journal articles published in English.. Articles were segregated according to methodology and appraised using the Mixed Methods Appraisal Tool.

RESULTS

A total of 5355 papers were identified with five quantitative and 13 qualitative included in the review. Four types of interventions were identified: eye movement desensitisation and reprocessing, trauma focussed CBT, debriefing and expressive writing. All showed some effectiveness in treating PTSDFC. Themes emerging from the meta-synthesis included women finding it difficult to recognise having a problem, needing validation and only seeking help 'at breaking point'. Women wanted health professionals actively asking in a non-judgemental way at different time points and providing support and listening, ideally with continuity of carer to make sense of their experiences.

LIMITATIONS

Quantitative studies were not disaggregated by intervention timing or follow-up duration. A single independent reviewer with team discussion was utilised.

CONCLUSION

There is little definitive evidence assessing the effectiveness of psychological interventions for PTSDFC. There are psychological barriers for women accessing help for traumatic childbirth which services can mitigate.

Infant-Family Mental Health in the NICU: A Mixed-Methods Study Exploring Referral Pathways and Family Engagement

Parents and infants in the neonatal intensive care unit (NICU) are exposed to considerable stress, and infant-family mental health (IFMH) services foster emotional well-being in the context of the parent-infant relationship. This mixed-methods study examined the role of an IFMH program introduced in a level 4 NICU. The study included (1) retrospective medical record review of NICU patients who were referred to the IFMH program and (2) qualitative interviews with NICU nurse managers, neonatologists, and medical social workers to explore their understanding of the IFMH program, explore the referral pathways and factors that supported family engagement, and identify specific recommendations for program improvement. Of the 311 infant-parent dyads referred to the IFMH program, 62% had at least one session and Spanish-speaking families were more likely to engage. Of those families receiving services, about one-third had brief intervention, one-third had 4 to 10 sessions, and one-third had long-term services, including in-home after-discharge services. Qualitative interviews with health providers identified unique qualities of the IFMH program and why families were and were not referred to the program. Recommendations centered on adding a full-time IFMH mental health provider to the NICU and increasing communication and integration between the IFMH program and the medical team.

Creative Music Therapy with Premature Infants and Their Parents: A Mixed-Method Pilot Study on Parents' Anxiety, Stress and Depressive Symptoms and Parent-Infant Attachment

Premature birth is stressful for infants and parents and can adversely affect the parent–infant dyad. This mixed-methods pilot study evaluates whether creative music therapy (CMT) can alleviate anxiety, stress, and depressive symptoms in parents and support the bonding process with their infant. Sixteen parent couples were included. Ten couples were randomly allocated to the music therapy group (MTG) and six to the control group (CG). All couples completed psychological questionnaires measuring anxiety and depressive symptoms as well as an implicit measure of parent–infant attachment at two weeks postpartum (T1), at approximate neonatal intensive care unit (NICU) hospitalization halftime (T2), and two weeks after the infant had been discharged (T3). At T1 and T2, the parents additionally completed a questionnaire assessing the degree of stress they experienced at the NICU. Qualitative data were collected through a semi-structured, problem-centered interview with MTG parents at T3. The results of the quantitative analyses revealed reductions in anxiety levels from T1 to T2 (p = 0.002) as well as decreases in depressive symptoms from T2 to T3 (p = 0.022). No such changes were apparent in the CG. In fact, parental stress increased from T1 to T2 (p = 0.016). Significant increases in attachment across time were also observed within the MTG, but not in the CG. The qualitative inquiry confirmed that CMT can support the parent–infant relationship. Being in musical interaction evoked feelings of joy and relaxation in the parents and encouraged them to interact more profoundly with their infant. The results call for a more extensive powered follow-up study to further investigate CMT’s potential for parental well-being and parent–infant bonding.

A guided participation nursing intervention to theraupeutic positioning and care (GP_Posit) for mothers of preterm infants: protocol of a pilot randomized controlled trial

Background

In the NICU, interventions intended to enhance maternal sensitivity are indicated in order to optimize preterm infant development and long-term mother-infant attachment. A novel nursing intervention was developed following a theory-oriented methodology and is based upon the guided participation theory for mothers to participate in their preterm infant's therapeutic POSITioning and care (GP_Posit). The primary objective of this study is to evaluate the feasibility and acceptability of (i) the study design; and (ii) the experimental GP_Posit nursing intervention during NICU hospitalization. The secondary objective is to estimate the preliminary effects of GP_Posit on maternal and preterm infant outcomes.

Methods

A pilot parallel-group randomized clinical trial (RCT) was designed where mother-preterm infant dyads are being recruited and randomized to a control group (usual care) or experimental group (GP_Posit intervention). Data collection includes feasibility and acceptability data as well as preliminary effects on maternal sensitivity and infant neurodevelopment. Ethical approval from the University Hospital ethical board was obtained in January 2018 (2017-1540).

Discussion

Data collection for this pilot study is expected to end in 2020. Results of this pilot study will inform about the feasibility and acceptability of the study design and GP_Posit intervention, a nursing intervention having the potential to favor maternal sensitivity and infant neurodevelopment in the NICU and guide the elaboration of a large-scale RCT.

A mother's bond: An ecological momentary assessment study of posttraumatic stress disorder symptoms and substance craving during pregnancy

Pregnant women with substance use disorder (SUD) comprise an underserved population with complex treatment needs, including complications from trauma histories and comorbid psychological disorders. Using ecological momentary assessment, we examined momentary fluctuations in posttraumatic stress disorder (PTSD) symptoms, prenatal bonding, and substance craving, among pregnant women in SUD treatment who had a history of trauma. We hypothesized that (a) PTSD symptoms and prenatal bonding would each be associated with substance craving and (b) PTSD symptoms would be negatively associated with prenatal bonding, and this would at least partially account for the association between PTSD symptoms and substance craving (i.e., indirect effect). Participants (n = 32) were on average 27.1 weeks pregnant (SD = 5.27), 27.8 years old (SD = 4.54), and predominantly Hispanic/Latina (66%). At the within subjects level, higher momentary ratings of PTSD symptoms were associated with lower quality (but not intensity of preoccupation) of prenatal bonding, which in turn was associated with greater craving. Lower quality of prenatal bonding partially mediated the positive association between PTSD symptoms and craving, which remained strong after accounting for prenatal bonding. Our results provide some preliminary support for considering interventions aimed at stabilizing or decreasing PTSD symptoms and stabilizing or increasing prenatal bonding to reduce substance craving and, thus, the risk of perinatal substance use among women with SUD and trauma histories.

Interactive behaviors between mothers and their prematurely born infants in the face-to-face Still-Face Paradigm

Abstract The present study compared and correlated interactive behaviors of 15 mothers and their very preterm infants (gestational age: 28-32 weeks). Mothers and infants were observed in the experimental Face-to-Face Still-Face paradigm, consisting of three episodes: in the first and third episodes (play and reunion episodes), mother and infant interact freely; in the second (still-face episode), the mother maintains a still-face expression. The behaviors of the infants were allocated in three categories: positive social orientation, negative social orientation and self-regulation. Maternal behaviors were classified into positive and negative social orientation. Intragroup comparisons indicated that maternal vocalizations were significantly higher in the play episode. Compared to other studies with preterm infants, babies in this study exhibit fewer interactive behaviors and more self-soothing behaviors in the still-face episode. In addition, in the reunion episode, values of the behaviors presented in the play episode were recovered. Correlations between intrusive maternal behaviors and noninteractive or negative-interaction behaviors of the infant suggest the relevance of providing intervention to promote maternal sensitivity.

Video feedback for parental sensitivity and attachment security in children under five years

BACKGROUND

Children who are securely attached to at least one parent are able to be comforted by that parent when they are distressed and explore the world confidently by using that parent as a 'secure base'. Research suggests that a secure attachment enables children to function better across all aspects of their development. Promoting secure attachment, therefore, is a goal of many early interventions. Attachment is mediated through parental sensitivity to signals of distress from the child. One means of improving parental sensitivity is through video feedback, which involves showing a parent brief moments of their interaction with their child, to strengthen their sensitivity and responsiveness to their child's signals.

OBJECTIVES

To assess the effects of video feedback on parental sensitivity and attachment security in children aged under five years who are at risk for poor attachment outcomes.

SEARCH METHODS

In November 2018 we searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, nine other databases and two trials registers. We also handsearched the reference lists of included studies, relevant systematic reviews, and several relevant websites SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs that assessed the effects of video feedback versus no treatment, inactive alternative intervention, or treatment as usual for parental sensitivity, parental reflective functioning, attachment security and adverse effects in children aged from birth to four years 11 months.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

This review includes 22 studies from seven countries in Europe and two countries in North America, with a total of 1889 randomised parent-child dyads or family units. Interventions targeted parents of children aged under five years, experiencing a wide range of difficulties (such as deafness or prematurity), or facing challenges that put them at risk of attachment issues (for example, parental depression). Nearly all studies reported some form of external funding, from a charitable organisation (n = 7) or public body, or both (n = 18). We considered most studies as being at low or unclear risk of bias across the majority of domains, with the exception of blinding of participants and personnel, where we assessed all studies as being at high risk of performance bias. For outcomes where self-report measures were used, such as parental stress and anxiety, we rated all studies at high risk of bias for blinding of outcome assessors. Parental sensitivity. A meta-analysis of 20 studies (1757 parent-child dyads) reported evidence of that video feedback improved parental sensitivity compared with a control or no intervention from postintervention to six months' follow-up (standardised mean difference (SMD) 0.34, 95% confidence interval (CI) 0.20 to 0.49, moderate-certainty evidence). The size of the observed impact compares favourably to other, similar interventions. Parental reflective functioning. No studies reported this outcome. Attachment security. A meta-analysis of two studies (166 parent-child dyads) indicated that video feedback increased the odds of being securely attached, measured using the Strange Situation Procedure, at postintervention (odds ratio 3.04, 95% CI 1.39 to 6.67, very low-certainty evidence). A second meta-analysis of two studies (131 parent-child dyads) that assessed attachment security using a different measure (Attachment Q-sort) found no effect of video feedback compared with the comparator groups (SMD 0.02, 95% CI -0.33 to 0.38, very low-certainty evidence). Adverse events. Eight studies (537 parent-child dyads) contributed data at postintervention or short-term follow-up to a meta-analysis of parental stress, and two studies (311 parent-child dyads) contributed short-term follow-up data to a meta-analysis of parental anxiety. There was no difference between intervention and comparator groups for either outcome. For parental stress the SMD between video feedback and control was -0.09 (95% CI -0.26 to 0.09, low-certainty evidence), while for parental anxiety the SMD was -0.28 (95% CI -0.87 to 0.31, very low-certainty evidence). Child behaviour. A meta-analysis of two studies (119 parent-child dyads) at long-term follow-up found no evidence of the effectiveness of video feedback on child behaviour (SMD 0.04, 95% CI -0.33 to 0.42, very low-certainty evidence). A moderator analysis found no evidence of an effect for the three prespecified variables (intervention type, number of feedback sessions and participating carer) when jointly tested. However, parent gender (both parents versus only mothers or only fathers) potentially has a statistically significant negative moderation effect, though only at α (alpha) = 0.1 AUTHORS' CONCLUSIONS: There is moderate-certainty evidence that video feedback may improve sensitivity in parents of children who are at risk for poor attachment outcomes due to a range of difficulties. There is currently only little, very low-certainty evidence regarding the impact of video feedback on attachment security, compared with control: results differed based on the type of measure used, and follow-up was limited in duration. There is no evidence that video feedback has an impact on parental stress or anxiety (low- and very low-certainty evidence, respectively). Further evidence is needed regarding the longer-term impact of video feedback on attachment and more distal outcomes such as children's behaviour (very low-certainty evidence). Further research is needed on the impact of video-feedback on paternal sensitivity and parental reflective functioning, as no study measured these outcomes. This review is limited by the fact that the majority of included parents were mothers.

Multiple session early psychological interventions for the prevention of post-traumatic stress disorder

BACKGROUND

The prevention of long-term psychological distress following traumatic events is a major concern. Systematic reviews have suggested that individual psychological debriefing is not an effective intervention at preventing post-traumatic stress disorder (PTSD). Over the past 20 years, other forms of intervention have been developed with the aim of preventing PTSD.

OBJECTIVES

To examine the efficacy of psychological interventions aimed at preventing PTSD in individuals exposed to a traumatic event but not identified as experiencing any specific psychological difficulties, in comparison with control conditions (e.g. usual care, waiting list and no treatment) and other psychological interventions.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, PsycINFO and ProQuest's Published International Literature On Traumatic Stress (PILOTS) database to 3 March 2018. An earlier search of CENTRAL and the Ovid databases was conducted via the Cochrane Common Mental Disorders Controlled Trial Register (CCMD-CTR) (all years to May 2016). We handsearched reference lists of relevant guidelines, systematic reviews and included study reports. Identified studies were shared with key experts in the field.We conducted an update search (15 March 2019) and placed any new trials in the 'awaiting classification' section. These will be incorporated into the next version of this review, as appropriate.

SELECTION CRITERIA

We searched for randomised controlled trials of any multiple session (two or more sessions) early psychological intervention or treatment designed to prevent symptoms of PTSD. We excluded single session individual/group psychological interventions. Comparator interventions included waiting list/usual care and active control condition. We included studies of adults who experienced a traumatic event which met the criterion A1 according to the Diagnostic and Statistical Manual (DSM-IV) for PTSD.

DATA COLLECTION AND ANALYSIS

We entered data into Review Manager 5 software. We analysed categorical outcomes as risk ratios (RRs), and continuous outcomes as mean differences (MD) or standardised mean differences (SMDs), with 95% confidence intervals (CI). We pooled data with a fixed-effect meta-analysis, except where there was heterogeneity, in which case we used a random-effects model. Two review authors independently assessed the included studies for risk of bias and discussed any conflicts with a third review author.

MAIN RESULTS

This is an update of a previous review.We included 27 studies with 3963 participants. The meta-analysis included 21 studies of 2721 participants. Seventeen studies compared multiple session early psychological intervention versus treatment as usual and four studies compared a multiple session early psychological intervention with active control condition.Low-certainty evidence indicated that multiple session early psychological interventions may be more effective than usual care in reducing PTSD diagnosis at three to six months' follow-up (RR 0.62, 95% CI 0.41 to 0.93; I2 = 34%; studies = 5; participants = 758). However, there was no statistically significant difference post-treatment (RR 1.06, 95% CI 0.85 to 1.32; I2 = 0%; studies = 5; participants = 556; very low-certainty evidence) or at seven to 12 months (RR 0.94, 95% CI 0.20 to 4.49; studies = 1; participants = 132; very low-certainty evidence). Meta-analysis indicated that there was no statistical difference in dropouts compared with usual care (RR 1.34, 95% CI 0.91 to 1.95; I2 = 34%; studies = 11; participants = 1154; low-certainty evidence) .At the primary endpoint of three to six months, low-certainty evidence indicated no statistical difference between groups in reducing severity of PTSD (SMD -0.10, 95% CI -0.22 to 0.02; I2 = 34%; studies = 15; participants = 1921), depression (SMD -0.04, 95% CI -0.19 to 0.10; I2 = 6%; studies = 7; participants = 1009) or anxiety symptoms (SMD -0.05, 95% CI -0.19 to 0.10; I2 = 2%; studies = 6; participants = 945).No studies comparing an intervention and active control reported outcomes for PTSD diagnosis. Low-certainty evidence showed that interventions may be associated with a higher dropout rate than active control condition (RR 1.61, 95% CI 1.11 to 2.34; studies = 2; participants = 425). At three to six months, low-certainty evidence indicated no statistical difference between interventions in terms of severity of PTSD symptoms (SMD -0.02, 95% CI -0.31 to 0.26; I2 = 43%; studies = 4; participants = 465), depression (SMD 0.04, 95% CI -0.16 to 0.23; I2 = 0%; studies = 2; participants = 409), anxiety (SMD 0.00, 95% CI -0.19 to 0.19; I2 = 0%; studies = 2; participants = 414) or quality of life (MD -0.03, 95% CI -0.06 to 0.00; studies = 1; participants = 239).None of the included studies reported on adverse events or use of health-related resources.

AUTHORS' CONCLUSIONS

While the review found some beneficial effects of multiple session early psychological interventions in the prevention of PTSD, the certainty of the evidence was low due to the high risk of bias in the included trials. The clear practice implication of this is that, at present, multiple session interventions aimed at everyone exposed to traumatic events cannot be recommended. There are a number of ongoing studies, demonstrating that this is a fast moving field of research. Future updates of this review will integrate the results of these new studies.

Joint observation in NICU (JOIN): study protocol of a clinical randomised controlled trial examining an early intervention during preterm care

INTRODUCTION

Preterm birth may generate significant distress among the parents, who often present with difficulties in appropriating their parental role. Parental stress and low perceived parental self-efficacy may interfere with the infant's socioemotional and cognitive development, particularly through disrupted parent-infant interactions. Perceived parental self-efficacy represents the belief of efficacy in caring for one's own infant and successful incarnation of the parental role, as well as the perception of one's own abilities to complete a specified task. Interventions to support parental role, as well as infant development, are needed, and parental self-efficacy represents a useful indicator to measure the effects of such early interventions.

METHODS AND ANALYSIS

This study protocol describes a randomised controlled trial that will test an early intervention in the neonatal intensive care unit (NICU) (JOIN: Joint Observation In Neonatology) carried out by an interdisciplinary staff team. Mothers of preterm neonates born between 28 and 32 6/7 weeks of gestational age are eligible for the study. The intervention consists of a videotaped observation by a clinical child psychologist or child psychiatrist and a study nurse of a period of care delivered to the neonate by the mother and a NICU nurse. The care procedure is followed by an interactive video guidance intended to demonstrate the neonate's abilities and resources to his parents. The primary outcome will be the difference in the perceived maternal self-efficacy between the intervention and control groups assessed by self-report questionnaires. Secondary outcomes will be maternal mental health, the perception of the parent- infant relationship, maternal responsiveness and the neurodevelopment of the infant at 6 months corrected age.

ETHICS AND DISSEMINATION

Ethical approval was granted by the Human Research Ethics Committee of the Canton de Vaud (study number 496/12). Results from this study will be disseminated at national and international conferences, and in peer-reviewed journals.

The interplay between prematurity, maternal stress and children's intelligence quotient at age 11: A longitudinal study

Very premature children (<33 weeks of gestational age (GA)) experience greater academic difficulties and have lower, though normal-range, intelligence quotients (IQs) versus their full-term peers. These differences are often attributed to GA or familial socio-economic status (SES). However, additional factors are increasingly recognized as likely contributors. Parental stress after a child's premature birth can present as post-traumatic stress disorder (PTSD) symptoms and can in turn reinforce difficulties in parent-child interaction pattern. Following a longitudinal design, we studied the interplay between a premature child's perinatal history and maternal PTSD symptoms on intelligence abilities assessed at 11 years of age. Thirty-three very preterm and 21 full-term mother-children dyads partook in the study. Children's perinatal risk was evaluated at hospital discharge, maternal PTSD symptoms were assessed when the children were 18 months old, and children's IQ was measured at 11 years old. IQ was significantly lower for preterm than full-term children, without reliable influences from perinatal risk scores. However, lower maternal PTSD symptoms predicted higher IQ in preterm children. This preliminary study highlights the importance detecting maternal PTSD symptoms after a preterm birth and suggests interventions should target reducing maternal PTSD symptoms during early childhood to enhance very preterm children's intelligence development.

Early psychological intervention following recent trauma: A systematic review and meta-analysis

Background: Post-traumatic stress disorder (PTSD) is a common and debilitating disorder which has a significant impact on the lives of sufferers. A number of early psychological interventions have been developed to try to prevent chronic difficulties. Objective: The objective of this study was to establish the current evidence for the effectiveness of multiple session early psychological interventions aimed at preventing or treating traumatic stress symptoms beginning within three months of trauma exposure. Methods: Randomized controlled trials of early multiple session psychological interventions aimed at preventing or reducing traumatic stress symptoms of individuals exposed to a traumatic event, fulfiling trauma criteria for an ICD or DSM diagnosis of PTSD were identified through a search of the Cochrane Common Mental Disorders Group Clinical Trials Registers database, the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO and PILOTS. Two authors independently extracted study details and data and completed risk of bias assessments. Analyses were undertaken using Review Manager software. Quality of findings were rated according to 'Grades of Recommendation, Assessment, Development, and Evaluation' (GRADE) and appraised for clinical importance. Results: Sixty-one studies evaluating a variety of interventions were identified. For individuals exposed to a trauma who were not pre-screened for traumatic stress symptoms there were no clinically important differences between any intervention and usual care. For individuals reporting traumatic stress symptoms we found clinically important evidence of benefits for trauma-focused cognitive-behavioural therapy (CBT-T), cognitive therapy without exposure and eye movement desensitization and reprocessing (EMDR). Differences were greatest for those diagnosed with acute stress disorder (ASD) and PTSD. Conclusions: There is evidence for the effectiveness of several early psychological interventions for individuals with traumatic stress symptoms following trauma exposure, especially for those meeting the diagnostic threshold for ASD or PTSD. Evidence is strongest for trauma-focused CBT.

What's going on in my baby's mind? Mothers' executive functions contribute to individual differences in maternal mentalization during mother-infant interactions

Maternal mentalization refers to a mother's capacity to understand mental-states of herself and her child and to regard her child as a psychological agent. In mother-infant interactions, this capacity is commonly conceptualized as maternal mind-mindedness, which can be divided into two dimensions: appropriate and nonattuned interpretations of the infants' mental-states. Appropriate mind-mindedness refers to interpretations that seem to be compatible with the infant's behaviors, whereas nonattuned mind-mindedness refers to noncompatible interpretations. The aim of this study was to investigate the cognitive mechanisms that contribute to mind-mindedness. Specifically, we investigated the role of executive functions in appropriate and nonattuned mind-mindedness, and the moderating roles of two infant-related factors, prematurity (as a stressful context) and child temperament (as a context of unpredictability and negative emotionality). To this end, mother-infant free play interactions were coded for mind-mindedness in a sample of 102 mothers and their 6-month-old infants (61 preterm, 41 full-term). When children were 66-months old, mothers completed cognitive tasks that assessed working memory updating, resistance to interference, response inhibition, and shifting. Appropriate mind-mindedness was positively associated with updating, and this link was stronger when infant temperament was rated as more difficult. Furthermore, among mothers of full-term infants, mothers' resistance to interference was negatively associated with nonattuned mind-mindedness. This link was not evident in the stressful context of premature birth. Mothers' response inhibition and shifting were not associated with either of the mind-mindedness dimensions. Implications on understanding variability in maternal mentalization during mother-infant interactions and the roles of executive functions in parenting are discussed.

Maternal sensitivity is associated with configural processing of infant's cues in preterm and full-term mothers

BACKGROUND

Prematurity may affect mother-infant bonding and alter maternal sensitivity to infant's cues. Efficient perception of infants' facial and bodily cues is a crucial aspect of maternal sensitivity and may be challenged by prematurity, as infants' signals may not be easily intelligible. However, it is still unexplored how premature birth impacts the maternal ability to perceive infants' signals.

AIMS

To investigate whether prematurity influences the perceptual sensitivity of mothers to infants' cues and, in particular, the configural processing of the faces and bodies of familiar and unfamiliar infants.

STUDY DESIGN

The inversion effect paradigm was used to evaluate the configural vs. detail-based processing of the face and body of own or others' infants. Preterm mothers were compared to full-term mothers with either low or high maternal sensitivity.

PARTICIPANTS

Forty-three healthy full-term and twenty-one preterm mothers of infants aged about six months.

OUTCOME MEASURES

Maternal sensitivity during dyadic interaction, gestational age, accuracy and reaction time in a delayed matching-to-sample task of upright vs. inverted body and face stimuli (i.e., inversion effect).

RESULTS

Preterm mothers were found to be less sensitive than the full-term ones. Higher maternal sensitivity during dyadic interaction was associated with lower inversion effect for unfamiliar as compared to own infants' bodies. However, preterm mothers and full-term mothers with low sensitivity showed comparable inversion effect in perceiving unfamiliar infants' faces or bodies.

CONCLUSIONS

Preterm birth per se does not directly affect body configural processing, but it may be associated to reduced maternal sensitivity, ultimately leading to a less refined perception of own infant's cues.

Effect of skin-to-skin contact on parents' sleep quality, mood, parent-infant interaction and cortisol concentrations in neonatal care units: study protocol of a randomised controlled trial

INTRODUCTION

Separation after preterm birth is a major stressor for infants and parents. Skin-to-skin contact (SSC) is a method of care suitable to use in the neonatal intensive care unit (NICU) to minimise separation between parents and infants. Less separation leads to increased possibilities for parent-infant interaction, provided that the parents' sleep quality is satisfactory. We aimed to evaluate the effect of continuous SSC on sleep quality and mood in parents of preterm infants born <33 weeks of gestation as well as the quality of parent-infant interaction and salivary cortisol concentrations at the time of discharge.

METHODS AND ANALYSIS

A randomised intervention study with two arms-intervention versus standard care. Data will be collected from 50 families. Eligible families will be randomly allocated to intervention or standard care when transferred from the intensive care room to the family-room in the NICU. The intervention consists of continuous SSC for four consecutive days and nights in the family-room. Data will be collected every day during the intervention and again at the time of discharge from the hospital. Outcome measures comprise activity tracker (Actigraph); validated self-rated questionnaires concerning sleep, mood and bonding; observed scorings of parental sensitivity and emotional availability and salivary cortisol. Data will be analysed with pairwise, repeated measures, Mann Whitney U-test will be used to compare groups and analysis of variance will be used to adjust for different hospitals and parents' gender.

ETHICS AND DISSEMINATION

The study is approved by the Regional Research Ethics Board at an appropriate university (2016/89-31). The results will be published in scientific journals. We will also use conferences and social media to disseminate our findings.

The trauma of birth

The trauma of birth is an international concern for all childbearing women globally. Since changes in 1994 to the Diagnostic Statistical Manual that included childbirth as a potentially traumatic event, several clusters of researchers, particularly representing the Scandinavian countries, the United Kingdom, and Australia, have emerged. Their research findings appear in numerous publications; yet, what is known from these studies is based on a variety of methodological designs and differing measurement tools making it difficult to draw many firm conclusions (Ayers, 2004 ; Ayers, Joseph, Mc-Kenzie-McHarg, Slade, & Wijma, 2008 ). This review offers information obtained from frequently cited, current and seminal research studies describing the trauma of birth among women of the world.

Preventing post-traumatic stress disorder following childbirth and traumatic birth experiences: a systematic review

INTRODUCTION

Between 9 and 44% of women experience giving birth as traumatic, and 3% of women develop a post-traumatic stress disorder following childbirth. Knowledge on risk factors is abundant, but studies on treatment are limited. This study aimed to present an overview of means to prevent traumatic birth experiences and childbirth-related post-traumatic stress disorder.

MATERIAL AND METHODS

Major databases [Cochrane; Embase; PsycINFO; PubMed (Medline)] were searched using combinations of the key words and their synonyms.

RESULTS

After screening titles and abstracts and reading 135 full-text articles, 13 studies were included. All evaluated secondary prevention, and none primary prevention. Interventions included debriefing, structured psychological interventions, expressive writing interventions, encouraging skin-to-skin contact with healthy newborns immediately postpartum and holding or seeing the newborn after stillbirth. The large heterogeneity of study characteristics precluded pooling of data. The writing interventions to express feelings appeared to be effective in prevention. A psychological intervention including elements of exposure and psycho-education seemed to lead to fewer post-traumatic stress disorder symptoms in women who delivered via emergency cesarean section.

CONCLUSIONS

No research has been done on primary prevention of traumatic childbirth. Research on secondary prevention of traumatic childbirth and post-traumatic stress disorder following delivery provides insufficient evidence that the described interventions are effective in unselected groups of women. In certain subgroups, results are inhomogeneous.

Validating the Psychometric Characteristics of the Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ) in a Chinese Context

BACKGROUND

Perinatal posttraumatic stress disorder (PPTSD) is a common stress-induced mental disorder worldwide. The Perinatal Posttraumatic Stress Disorder Questionnaire (PPQ) is an excellent questionnaire that measures the symptoms of PPTSD, but has not been translated into Chinese yet.

OBJECTIVES

The aims of this study were to develop a translated Chinese version of the (PPQ) and validate the psychometric characteristics of the PPQ in a Chinese context.

METHODS

After translation, back-translation, and expert discussion, 280 mothers at 1 to 18months postpartum filled out the questionnaires through the Internet. Then the reliability and validity of the translated questionnaire were tested.

RESULTS

The Chinese version of PPQ (PPQ-C) was composed of 14 items. Cronbach's α coefficient was 0.84, test-retest reliability was 0.88, and the content validity was 0.99. Exploratory factor analysis extracted three factors (representing "arousal", "avoidance" and "intrusion") accounted for 53.30% of the variance. The established 3 factors model was well fitted with the collected data (χ²=76.40, p<0.05).

IMPLICATIONS FOR PRACTICE

The PPQ-C is a short, reliable, and valid instrument that measures the symptoms of PPTSD, and it is recommend for clinical screening.

IMPLICATIONS FOR RESEARCH

Further research could involve diverse participants, as well as better adapt the PPQ-C to Chinese culture.

Postnatal post-traumatic stress: An integrative review

PROBLEM

Post-traumatic stress disorder and post-traumatic stress symptoms following birth occur amongst a small proportion of women but can lead to poor maternal mental health, impairment in mother-infant bonding and relationship stress. This integrative review aims to examine the associated risk factors and women's own experiences of postnatal post-traumatic stress in order to better understand this phenomenon.

METHOD

Fifty three articles were included and critically reviewed using the relevant Critical Appraisal Skills Program checklists or Strengthening the Reporting of Observational studies in Epidemiology assessment tool.

FINDINGS

Risk factors for postnatal post-traumatic stress symptoms and disorder include factors arising before pregnancy, during the antenatal period, in labour and birth and in the postnatal period. Potential protective factors against postnatal post-traumatic stress have been identified in a few studies. The development of postnatal post-traumatic stress can lead to negative outcomes for women, infants and families.

DISCUSSION

Risk factors for post-traumatic stress symptoms and disorder are potentially identifiable pre-pregnancy and during the antenatal, intrapartum and postnatal periods. Potential protective factors have been identified however they are presently under researched. Predictive models for postnatal post-traumatic stress disorder development have been proposed, however further investigation is required to test such models in a variety of settings.

CONCLUSIONS

Postnatal post-traumatic stress symptoms and disorder have been shown to negatively impact the lives of childbearing women. Further investigation into methods and models for identifying women at risk of developing postnatal post-traumatic stress following childbirth is required in order to improve outcomes for this population of women.

The Effect of a Social-Emotional Intervention on the Development of Preterm Infants in Institutions

This study examined the effect of a social-emotional intervention implemented in one St. Petersburg (Russian Federation) institution (called a Baby Home, BH) on the general behavioral development of preterm children (gestational ages of 30-36 weeks) during their first two years of life. The intervention consisted of training caregivers and implementing structural changes to create a more family-like environment. The study included preterm (N = 56) and full-term (N = 93) children from one BH that implemented the intervention and from another BH with no intervention. Children were assessed at 3, 6, 9, 12, 18 and 24 months of age with the Battelle Development Inventory (LINC Associates, 1988). The results showed that the intervention positively influenced the general behavioral development of BH preterm children throughout their first two years of life compared to preterms from the no-intervention BH. Also, results indicated that the intervention effect was developmentally similar for preterm and for full-term children, but preterm children consistently scored lower than full-terms during their first two years living in the BH. In general, our research emphasizes the crucial role of warm, sensitive, and responsive interactions with a constant and emotionally available caregiver for healthy child development for both term and preterm children.

Maternal Sensitivity: a Resilience Factor against Internalizing Symptoms in Early Adolescents Born Very Preterm?

Compared with full-terms, preterm individuals are more at risk from infancy to adulthood for developing internalizing symptoms. Early maternal interactive behavior, especially maternal sensitivity, has been found to be a resilience factor in the developmental outcome of preterm children. The present longitudinal study aimed at examining whether early interactive parenting behaviors have a long term impact on the internalizing symptoms of preterm-born young adolescents. A total sample of 36 very preterm and 22 full-term children participated in an 11-year follow-up study. Maternal interactive behavior was assessed during a mother-infant interaction when the infant was 18 months old. At 11 years, internalizing symptoms were assessed with the Child Behavior Checklist (CBCL). Hierarchical regression analyses revealed that the interaction between groups (preterm/full-term) and maternal sensitivity at 18 months significantly explained CBCL internalizing symptoms at 11 years (β = -0.526; p < 0.05). Specifically, although prematurity was related to internalizing problems, preterm children with higher maternal sensitivity did not differ from their full-term-born peers on the CBCL internalizing problems domain. These results suggest that maternal sensitivity is a long-term resilience factor preventing the development of internalizing problems at early adolescence in very preterm individuals.

Risk factors for the development of post-traumatic stress disorder and coping strategies in mothers and fathers following infant hospitalisation in the neonatal intensive care unit

AIMS AND OBJECTIVES

The aim of this study was to identify the potential risk factors for the development of post-traumatic stress disorder in mothers and fathers following infant hospitalisation in the neonatal intensive care unit.

BACKGROUND

The development of neonatal intensive care units has increased the survival rate of infants. However, one of the major parental problems is post-traumatic stress disorder.

DESIGN

An observational study covered 125 parents (72 mothers and 53 fathers) of infants aged 3-12 months who were hospitalised in the neonatal intensive care unit during the neonatal period.

SETTING

Third-referral neonatal intensive care unit. Several standardised and self-reported research tools were used to estimate the level of post-traumatic stress symptoms (Impact Event Scale-Revised), perceived stress (Perceived Stress Scale) and coping strategies (COPE Inventory). The respondents also completed a Parent and Infant Characteristic Questionnaire.

RESULTS

The mothers and fathers did not differ in their parental and infant characteristics. Post-traumatic stress disorder was present in 60% of the mothers and 47% of the fathers. Compared to the fathers, the mothers felt greater stress (p = .020) and presented a higher severity of post-traumatic stress disorder (p < .001). Previous miscarriages (p = .023) and the presence of chronic diseases (p = .032) were risk factors for post-traumatic stress disorder in the mothers. In the fathers, an Apgar test at 1 min after birth (p = .030) and a partner's post-traumatic stress disorder (p = .038) were related to post-traumatic stress disorder. The mothers compared to the fathers were more likely to use strategies such as: positive reinterpretation and growth, focusing on and venting of emotions, instrumental social support, religious coping and acceptance. In the fathers, the predictors included an Apgar score at 1 min after birth, a lack of congenital anomalies in the child and mental disengagement.

CONCLUSION

Risk factors for post-traumatic stress disorder, as well as coping strategies, differ in women compare to men.

RELEVANCE TO CLINICAL PRACTICE

Knowledge of risk factors for post-traumatic stress disorder, specific to men and women, may help identify the parents in whom probability of the occurrence of this disorder is increased.

Parental engagement and early interactions with preterm infants during the stay in the neonatal intensive care unit: protocol of a mixed-method and longitudinal study

INTRODUCTION

The preterm infants' developmental outcomes depend on biological and environmental risk factors. The environmental factors include prolonged parental separation, less exposure to early mother/father-infant interactions and the parents' ability to respond to the trauma of premature birth. In the case of premature birth, the father's ability to take an active part in the care of the infant from the start is essential. The parents' emotional closeness to the preterm infant hospitalised in the neonatal intensive care unit (NICU) may be crucial to the well-being of the newborn, the development of mutual regulation, the establishment of a functioning parent-infant affective relationship and the parents' confidence in their ability to provide care for their baby.

METHODS AND ANALYSIS

This is a mixed-method, observational and longitudinal study. The methodological strategy will include: (1) ethnographic observation in a level III NICU located in Italy for a duration of 18 months; (2) 3-minute video recordings of mother-infant and father-infant interaction in the NICU; (3) a semistructured interview with fathers during the infants' hospital stay; (4) 3-minute video recordings of mother-infant and father-infant face-to-face interaction in the laboratory at 4 months of corrected age; (5) self-report questionnaires for parents on depression and quality of the couple relationship at the approximate times of the video recording sessions.

ETHICS AND DISSEMINATION

The study protocol was approved by the Ethical Committee for Clinical Trials of the Verona and Rovigo Provinces. Results aim to be published in international peer-reviewed journals, and presented at relevant national and international conferences. This research project will develop research relevant to (1) the quality and modalities of maternal and paternal communication with the preterm infant in the NICU; (2) the influence of maternal/paternal social stimulation on the infant behavioural states; (3) the quality and modalities of paternal support to the partner and possible influences on mother-infant relationship.

Posttraumatic Stress in Mothers Related to Giving Birth Prematurely: A Mixed Research Synthesis

BACKGROUND

Globally the preterm birth rate for 184 countries in 2010 was 11.1%. Preterm births can be a traumatic experience for mothers.

OBJECTIVE

This article provides a mixed research synthesis of the quantitative and qualitative studies on posttraumatic stress in mothers who have given birth prematurely.

DESIGN

Narrative synthesis was the mixed research synthesis approach used.

RESULTS

Included in this narrative synthesis were quantitative prevalence studies ( n = 19), quantitative intervention studies ( n = 6), and qualitative studies ( n = 5). Prevalence rates ranged from 14% to 79%. Four of the intervention studies had significant results and two did not. Qualitative data synthesis revealed five themes: (a) shocked and horrified, (b) consuming guilt, (c) pervasive anxiety and hypervigilance, (d) intrusive thoughts, and (e) numbing and avoiding reminders.

CONCLUSIONS

Women's traumatic experiences of preterm birth are clearly important issues for psychiatric nurses to address.
