Acute Traumatic Stress in Neonatal Intensive Care Unit Parents: Relation to Existential Emotion-Based Personality Predispositions

The Prevalence of PTSD of Mothers and Fathers of High-Risk Infants Admitted to NICU: A Systematic Review

Admission of a preterm or sick full-term infant to the neonatal intensive care unit (NICU) is a stressful experience for parents. Indeed, the 'NICU experience' may constitute a traumatic event for parents, distinct from other birth-related trauma, leading to significant and ongoing posttraumatic stress disorder (PTSD) symptoms. However, the rates at which this outcome occurs are not well understood. This review aimed to identify the prevalence of PTSD in mothers and fathers of high-risk infants admitted to the NICU, specifically focusing on the NICU experience as the index trauma. The PRISMA-P: Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols were used to conduct this review. We searched PsycINFO, PubMed, Scopus, EMBASE, Web of Science, ProQuest Dissertations and Theses databases, and reference lists of included articles (1980-2021). Two independent reviewers screened titles and abstracts and conducted the full-text screening assessment. Of the 707 records identified, seven studies met the inclusion criteria. In this systematic review, PTSD symptomatology was assessed by self-report measures rather than a clinical interview. We identified significant variations in the methodologies and quality between studies, with a wide variation of reported prevalence rates of PTSD of 4.5-30% in mothers and 0-33% in fathers. Overall, the findings indicate that up to one-third of parents experience PTSD symptomatology related to the NICU experience. These results emphasize the importance of universal routine antenatal and postnatal screening for symptoms of PTSD to identify parents at risk of distress during the NICU experience and after discharge.Trial registration: The study protocol was registered with Prospero registration number CRD42020154548 on 28 April 2020.

Prevalence of anxiety and post-traumatic stress (PTS) among the parents of babies admitted to neonatal units: A systematic review and meta-analysis

BACKGROUND

Parents of babies admitted to neonatal units (NNU) are exposed to a range of potentially distressing experiences, which can lead to mental health symptoms such as increased anxiety and post-traumatic stress (PTS). This review aimed to describe how anxiety and PTS are defined and assessed, and to estimate anxiety and PTS prevalence among parents of babies admitted to NNU.

METHOD

Medline, Embase, PsychoINFO, Cumulative Index to Nursing and Allied Health literature were searched to identify studies published prior to April 14, 2021. Included studies were assessed using Hoy risk of bias tool. A random-effects model was used to estimate pooled prevalence with 95% CIs. Potential sources of variation were investigated using subgroup analyses and meta-regression. The review is registered with PROSPERO (CRD42020162935).

FINDINGS

Fifty six studies involving 6,036 parents met the review criteria; 21 studies assessed anxiety, 35 assessed PTS, and 8 assessed both. The pooled prevalence of anxiety was 41.9% (95%CI:30.9, 53.0) and the pooled prevalence of PTS was 39.9% (95%CI:30.8, 48.9) among parents up to one month after the birth. Anxiety prevalence decreased to 26.3% (95%CI:10.1, 42.5) and PTS prevalence to 24.5% (95%CI:17.4, 31.6) between one month and one year after birth. More than one year after birth PTS prevalence remained high 27.1% (95%CI:20.7, 33.6). Data on anxiety at this time point were limited. There was high heterogeneity between studies and some evidence from subgroup and meta-regression analyses that study characteristics contributed to the variation in prevalence estimates.

INTERPRETATION

The prevalence of anxiety and PTS was high among parents of babies admitted to NNU. The rates declined over time, although they remained higher than population prevalence estimates for women in the perinatal period. Implementing routine screening would enable early diagnosis and effective intervention.

Posttraumatic stress in NICU mothers: modeling the roles of childhood trauma and infant health

OBJECTIVE

To evaluate acute stress disorder (ASD) symptoms and their predictors in Neonatal Intensive Care Unit (NICU) mothers.

STUDY DESIGN

In this cross-sectional study, 119 mothers (~72% Medicaid) completed surveys during the first month of their infants' hospitalizations. Correlations and structural equation models (SEMs) evaluated relations among mothers' childhood trauma history, infant health appraisals, objective infant health, and ASD.

RESULT

ASD symptoms (~55%) and childhood trauma (~33%) were prevalent. ASD was correlated with childhood trauma, infant health, and infant health appraisals. All SEMs had good fit, indicating that (a) infant health appraisals partially mediated relations between childhood trauma and ASD, and (b) infant health appraisals fully mediated relations between objective infant health and ASD.

CONCLUSION

ASD symptoms are prevalent among NICU mothers regardless of infant health severity. Recognition of childhood trauma history and appraisals of infant health is critical for trauma-informed care.

Emotional disorganization: The prominent experience of Iranian mothers with preterm neonate: A qualitative study

When a preterm neonate is born and needs to be taken care of in the neonatal intensive care unit (NICU), the mother experiences a different process of mothering. A grounded theory study was conducted to explore the maternal role attainment in mothers of preterm infants. The authors of this paper report the most prominent experience of Iranian mothers with preterm neonates during their stay in the NICU that emerged as part of the process of maternal role attainment. Data were collected through in-depth semi-structured interviews with mothers in the NICU. We found four categories as emerged from experiences that formed the concept of "emotional disorganization". We argue that these findings can help caregivers and nurses to provide sensitive and supportive care to mothers of preterm neonates.

Shame and guilt in the postnatal period: a systematic review

Objective: The aim of this review was to explore the unique contribution of shame (negative evaluation of the self) and guilt (negative evaluation of behaviour) to postnatal psychological symptoms. Background: Although shame and guilt are related to psychological symptoms, the separate effect of each in postnatal psychological symptoms are not yet known. Methods: Seven electronic databases were systematically reviewed for articles on: (1) quantitative measures of shame, guilt, and psychological symptoms (2) in the postnatal period for infants under two years of age (3) published in English. Results: Of the 1,615 articles retrieved using PRISMA guidelines, five met criteria and were analysed independently by two reviewers using the STROBE criteria. In mothers, shame was significantly related to stress and postnatal depression. Shame significantly predicted postnatal depression. Guilt was significantly related to postnatal depression; however, the relationship was substantially reduced when included with shame. In fathers, shame, but not guilt, was significantly related to stress, anxiety, and depression. Conclusion: Shame and guilt are trans-diagnostic phenomena, negatively impacting on postnatal psychological health, and potentially the parent-child relationship. More research is needed to develop awareness of the unique effects of shame and guilt to optimise perinatal intervention.

Acute and Post-traumatic Stress Disorder Symptoms in Mothers and Fathers Following Childbirth: A Prospective Cohort Study

Introduction: Up to 30% of women view their childbirth as traumatic. This experience can lead to acute stress disorder or post-traumatic stress disorder. The negative impact of maternal post-traumatic stress disorder following childbirth reaches beyond the mother, potentially affecting her child's development and the couple's relationship. Research on paternal post-traumatic stress disorder following childbirth is scarce. Acute stress disorder is suggested to be an important predictor of post-traumatic stress disorder in mothers, but little is known about paternal acute stress disorder following childbirth. Furthermore, there is limited information about the comparison or relation of acute stress disorder and post-traumatic stress disorder following childbirth between parents. Aim: [1] To compare the prevalence rates and severity of acute stress disorder and post-traumatic stress disorder symptoms between parents following childbirth by taking anxiety and depression symptoms, as well as obstetric variables and previous traumatic events into account and [2] To determine if acute stress disorder is a predictor of post-traumatic stress disorder. Method: A prospective population-based design was used. N = 647 participants were recruited from future parents who attended appointments at the Obstetrics and Gynecology unit at a Swiss university hospital. Self-report questionnaires were used: Post-traumatic Diagnostic Scale in the third trimester of pregnancy (T1) and 1 month post-partum (T3), Acute Stress Disorder Scale at 1 week post-partum (T2), and Hospital Anxiety and Depression Scale at all time points. Obstetric and neonatal variables were retrieved from hospital records. Results: At T2, 63.9% of mothers and 51.7% of fathers presented symptoms of acute stress disorder. At T3, 20.7% of mothers and 7.2% of fathers had symptoms of post-traumatic stress disorder. Acute stress disorder was a predictor of post-partum post-traumatic stress disorder (Odds ratio: 8.6, IC 95% [1.85; 40.42]). Depression symptoms was a significant confounder in the prediction of post-traumatic stress disorder following childbirth, but not anxiety or previous perinatal loss. Conclusion: Little is known about parental differences in acute stress disorder and post-traumatic stress disorder symptoms following childbirth. Results indicate that both parents may suffer from acute stress disorder and post-traumatic stress disorder symptoms after childbirth and that acute stress disorder is a predictor of post-traumatic stress disorder after childbirth for both parents. Sensitization of maternity staff to these results may assist in earlier identification of and appropriate treatment for at-risk parents.

Mindfulness-Based Strategies: A Cost-Effective Stress Reduction Method for Parents in the NICU

Stress in parents who have an infant in the NICU is well documented in literature. Prematurity and related comorbid conditions, high-tech NICU environments, presence of multidisciplinary health care professionals, altered parenting roles, and concerns of health outcomes in the infant are common stress factors. Further, inadequate management of stress can result in poor parent-infant bonding, poor infant outcome, and postpartum depression in parents. Effective stress management strategies may help parents adapt to their parental role thereby improving infant outcomes. Research has shown mindfulness-based strategies help reduce stress in the general population. Can this strategy be applied in the context of parents of infants in the NICU? Literature is scant on the impact of mindfulness-based strategies on parents of infants in the NICU and on the infant's health outcomes. This article explores the application of mindfulness-based strategies to reduce stress in parents of infants in the NICU.

Personality Traits, State Positive and Negative Affect, and Professional Quality of Life in Neonatal Nurses

OBJECTIVE

To explore the relationships of core self-evaluations of personality (self-esteem, generalized self-efficacy, emotional stability, and internal locus of control), the five-factor model personality traits (neuroticism, agreeableness, extraversion, conscientiousness, and openness), and positive and negative affect with neonatal nurses' professional quality of life (burnout, secondary traumatic stress, and compassion satisfaction).

DESIGN

Cross-sectional cohort study.

SETTING

Four Level 3-4 NICUs in New South Wales, Australia.

PARTICIPANTS

One hundred forty-two (35%) of 405 eligible neonatal nurses.

METHODS

Online self-report measures of personality traits, positive and negative affect, and professional quality of life.

RESULTS

Core self-evaluations explained 33%, 21%, and 26% of the variance in burnout, secondary traumatic stress, and compassion satisfaction, respectively. After controlling for core self-evaluations, agreeableness, neuroticism, and extraversion contributed to the respective variances in burnout, secondary traumatic stress, and compassion satisfaction. After controlling for core self-evaluations and the five-factor model personality traits, positive affect contributed to the variance in burnout and compassion satisfaction, whereas negative affect contributed to the variance in secondary traumatic stress. No five-factor model personality trait contributed to the variance in professional quality of life in the final regression models. Positive affect mediated the effect of core self-evaluations on burnout and compassion satisfaction, whereas negative affect mediated the effect of core self-evaluations on secondary traumatic stress.

CONCLUSION

Neonatal nurses should be aware of and accept responsibility for personality traits and moods that benefit or detract from their professional quality of life. NICU nurse managers should ensure that neonatal nurses have ready access to psychological support services.

Posttraumatic Stress in Mothers While Their Preterm Infants Are in the Newborn Intensive Care Unit: A Mixed Research Synthesis

In this mixed research synthesis on posttraumatic stress in mothers related to their preterm infants' stay in the newborn intensive care unit (NICU), we synthesized and integrated a total of 37 studies, 25 of which were quantitative and 12 were qualitative studies. The prevalence rates of NICU mothers with elevated posttraumatic stress symptoms ranged from 18% in the United States to 81% in Turkey. Nine of the 12 studies testing interventions to decrease mothers' stress related to their NICU experiences reported significant results. Content analysis of the qualitative studies' findings revealed 5 themes: stark contrast to images of joyous motherhood, cultural overlay, issues of ownership and control, support, and learning to be a NICU mother.

The five-factor model of personality, work stress and professional quality of life in neonatal intensive care unit nurses

AIMS

The study aim was to determine the direct and indirect relations of the five-factor model of personality traits and work stress with professional quality of life in neonatal nurses.

BACKGROUND

Neonatal intensive care nursing has positive and negative effects on neonatal nurses' psychological well-being. Although individual and situational factors interact to influence professional quality of life, there have been few studies of these relationships in neonatal nurses.

DESIGN

A cross-sectional study conducted in 2016.

METHODS

Self-report questionnaires were used to measure professional quality of life (burnout, secondary traumatic stress and compassion satisfaction), five-factor model of personality traits (neuroticism, agreeableness, extraversion, conscientiousness and openness) and work stress (role ambiguity, role conflict and role overload).

RESULTS

One hundred and forty (34%) of 405 eligible neonatal nurses provided the data. After controlling for work stress, neuroticism and agreeableness were related to burnout, neuroticism was related to secondary traumatic stress, and extraversion was related to compassion satisfaction. Work stress controlled for personality traits was related to burnout and secondary traumatic stress, but not to compassion satisfaction. Neuroticism moderated the effect of work stress on secondary traumatic stress and agreeableness and openness moderated the effect of work stress on compassion satisfaction. Work stress mediated the effect of neuroticism and extraversion on burnout and the effects of extraversion and conscientiousness on compassion satisfaction.

CONCLUSION

Strategies to reduce work stress may not lessen burnout and secondary traumatic stress or increase compassion satisfaction in neonatal nurses who are prone to high neuroticism, low agreeableness and low extraversion.

Scoping Review of the Mental Health of Parents of Infants in the NICU

OBJECTIVE

To synthesize and summarize evidence regarding the mental health of parents of infants in the NICU.

DATA SOURCES

Thirteen electronic databases were searched in October 2014 using the following terms individually and in combination: postpartum woman, mother, NICU, preterm birth, depression, anxiety, acute stress disorder (ASD), posttraumatic stress disorder (PTSD), and parental stress.

STUDY SELECTION

We examined the published research regarding the experiences of parents who have infants admitted to the NICU, the mental health problems that parents may develop, the tools that have been used to identify such problems, and factors related to parental mental health.

DATA EXTRACTION

After the exclusion of articles according to preset criteria, we included 66 articles in the full review.

DATA SYNTHESIS

Mental health issues are common in parents of infants in the NICU across diverse ethnocultural groups and countries. Parents report feelings of guilt and shame, high levels of stress, mood and anxiety symptoms, and the positive influence of specific coping strategies and social support. The ethnocultural meanings of these experience and thus nursing interventions may differ widely.

CONCLUSION

Ongoing assessments of the mental health of parents should be part of routine NICU care. Identification of mood and anxiety symptoms and testing innovative interventions to address at-risk or affected parents is imperative to ensure that there are culturally appropriate policies and services in place to respond to the mental health needs of NICU families.

Factor analysis of the Parental Stressor Scale in parents of term and near-term surgical newborns

OBJECTIVE

A confirmatory factor analysis (CFA) of the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS:NICU) in parents of term and near-term surgical newborns.

BACKGROUND

The PSS:NICU is a common measure of the stressors experienced by parents of NICU newborns. A CFA of the PSS:NICU has not been published.

METHODS

A CFA of the 26-item version of the PSS:NICU (PSS:NICU-26) was conducted using data from 216 parents of term and near-term surgical newborns. A multigroup CFA analysis was conducted to determine if the factor structure of the final PSS:NICU model was invariant across gender.

RESULTS

CFA showed the PSS:NICU-26 model was a poor fit for the data. Exploratory factor analysis and CFAs with post hoc modifications resulted in the exclusion of 10 PSS:NICU-26 items. The resultant PSS:NICU-16 model was a good fit for the data and the factor structure was invariant across gender.

CONCLUSION

The PSS:NICU-16 is a reliable measure of NICU-related parental stressors with a structure that is invariant across gender. Although the study findings should be replicated, researchers should consider using the PSS:NICU-16 in studies of parents of term and near-term surgical newborns and studies where a more parsimonious model of the PSS:NICU may be preferred.
