Maternal psychological distress and parenting stress after the birth of a very low-birth-weight infant

Predictors of depressive symptom trajectories in mothers of preterm or low birth weight infants

Predictors of maternal depression trajectories were examined longitudinally in families with an infant born preterm or at a low birth weight. A total of 181 mother-infant dyads enrolled in the study before the infant's neonatal intensive care unit (NICU) discharge. Maternal depressive symptoms were assessed at 5 timepoints, and contextual variables and infant risks were assessed at NICU discharge. Hierarchical linear models revealed that mothers who experienced more risk factors reported more depressive symptoms just before their infant's NICU discharge and showed less decline in depressive symptoms in the months immediately following the child's birth. Although cumulative risks predicted depression trajectories, this effect appeared driven by maternal and family sociodemographic risks rather than infant risks. Addition of family support as a covariate in the multilevel models with a subsample of families revealed that social support and depression covaried across time. However, most of the findings regarding the association between risk and depression remained consistent, whereas the effects of maternal race and multiple birth were slightly attenuated.

Parental mental health and child development from six to thirty-six months in a birth cohort study in Taiwan

This study investigated the reciprocity between parental mental health and the different stages of child development at 6, 18, and 36 months. As the pilot of a birth cohort study, this study comprised 2048 children and their parents who were randomly selected and invited to participate. The development of these children and the mental health of their parents were followed at 6, 18, and 36 months postpartum. Child development was assessed using the Taiwan Birth Cohort Study instrument, and parental health was assessed using the Taiwanese version of the 36-Item Short Form Health Survey. Complete responses for all three stages were received from 844 families. Our results showed that parental mental health had a direct effect on language and social development; however, this effect did not become significant until 36 months. The reciprocity between child development and parental mental health and proper intervention are vital.

How do mothers and fathers who have a child with a disability describe their adaptation/ transformation process?

This qualitative study explored the adaptation/transformation process in mothers and fathers at the individual, parental, marital and extrafamilial levels, and the similarities and differences in their experience of living with a child with cerebral palsy. Interviews were conducted with 13 mothers and 13 fathers of children with cerebral palsy. The results show that mothers and fathers are more likely to view the situation differently than similarly. For both parents, the situation offers the potential for transformation. Complementarity between mothers and fathers is an important factor in each of the adaptation or transformation subsystems. Both parents embark on a journey that changes their beliefs about difference, apply their new knowledge to every aspect of their life, and endeavour to normalize their situation.

Anxiety, dysphoria, and depression symptoms in mothers of preterm infants

To compare presence and severity of clinical symptoms of anxiety, dysphoria, and depression in mothers of preterm and of full-term infants and to observe changes in symptoms of mothers of preterm infants during hospitalization of the infants and after discharge, 50 mothers of preterm infants and 25 mothers of full-term infants completed the State-Trait Anxiety Inventory and the Beck Depression Inventory. The mothers with preterm infants had significantly higher clinical symptoms of State Anxiety during hospitalization than the group with full-term infants, but the clinical symptoms of anxiety in mothers of preterm infants decreased significantly after discharge. The health staff in a neonatal intensive care unit should not only be aware of infants' clinical status but also of the mothers' emotional state.

Psychological impact on women after second and third trimester termination of pregnancy due to fetal anomalies versus women after preterm birth--a 14-month follow up study

The objective of this study was to compare psychiatric morbidity and the course of posttraumatic stress, depression, and anxiety in two groups with severe complications during pregnancy, women after termination of late pregnancy (TOP) due to fetal anomalies and women after preterm birth (PRE). As control group women after the delivery of a healthy child were assessed. A consecutive sample of women who experienced a) termination of late pregnancy in the 2nd or 3rd-trimester (N = 62), or b) preterm birth (N = 43), or c) birth of a healthy child (N = 65) was investigated 14 days (T1), 6 months (T2), and 14 months (T3) after the event. At T1, 22.4% of the women after TOP were diagnosed with a psychiatric disorder compared to 18.5% women after PRE, and 6.2% in the control group. The corresponding values at T3 were 16.7%, 7.1%, and 0%. Shortly after the event, a broad spectrum of diagnoses was found; however, 14 months later only affective and anxiety disorders were diagnosed. Posttraumatic stress and clinician-rated depressive symptoms were highest in women after TOP. The short-term emotional reactions to TOP in late pregnancy due to fetal anomaly appear to be more intense than those to preterm birth. Both events can lead to severe psychiatric morbidity with a lasting psychological impact.

Post-traumatic stress symptoms in mothers of very low birth weight infants 2-3 years post-partum

We examined symptoms of post-traumatic stress disorder (PTSD) in mothers of very low birth weight (VLBW) infants 2-3 years post-partum, compared with mothers of term, normal weight infants. Mothers were asked to report current symptoms relating specifically to the birth of their infant using The Impact of Event Scale-Revised (IES-R). Mothers of VLBW infants recorded significantly higher levels of PTSD symptoms overall (median scores: VLBW 25 [range 2-82], versus controls: 0 [range 0-5], P < 0.001), and in all sub-categories (p < 0.001). These findings suggest that mothers of VLBW infants have a relatively high prevalence of symptoms of PTSD at 2-3 years postnatal.

Effects of interview on mood status of pregnant women with high-risk delivery

BACKGROUND

Expectant mothers at high risk for preterm labor admitted to the Mother and Child Health Centers (MCH) often have psychological problems and mood disturbances. The purpose of the present study was to evaluate the effects of an interview by health professionals on their mood status.

METHODS

Participants consisted of 52 women admitted to the MCH of Kansai Medical University (KMU) hospital and who had delivered between December 2006 and September 2007. Interview sessions by health professionals consisting of a neonatologist and a clinical psychologist, termed 'KMU baby doctor-team interview', were held once a week. During the interview the neonatologist discussed the physiology of preterm infants and treatment for the possible complications while the clinical psychologist listened to the expectant mothers talk about their anxieties or complaints and responded to their requests as much as possible. To investigate their mood status objectively, the participants were asked to complete the Japanese version of the Profile of Mood States (POMS) before and after the first session.

RESULTS

On admission, more than 20% of participants ranging from 19 to 42 years of age had mood disturbances in Tension-Anxiety, Depression-Dejection, and Vigor categorized by POMS. The average score for Depression-Dejection, however, significantly improved after the first interview sessions.

CONCLUSIONS

Mood disturbances were observed in a considerable number of expectant mothers at high risk for preterm labor. Interviews by health professionals consisting of a neonatologist and a clinical psychologist may alter their mood status.

Parents' Use of Nonmedical Support Services in the Neonatal Intensive Care Unit

Parents frequently identify the need for support while their infant is in the Neonatal Intensive Care Unit (NICU), however, they may simultaneously distance themselves from traditional family and friend support. Recognizing this, many NICUs provide additional nonmedical support services such as social workers, chaplains/religious counselors, and support groups. This article, part of a larger research study, suggests an inverse relationship between social support and the use of supportive services. In addition, parents in this study appear to use support services less often than would be anticipated based on their reports of utility. Suggestions are provided to potentially improve desirability/accessibility of these services.

Nutritional paradigms of ovine fetal growth restriction: Implications for human pregnancy

Low birth weight and prematurity are associated with short inter-pregnancy intervals, low pre-pregnancy weights, insufficient maternal weight gains during pregnancy, multifetal pregnancies and a young maternal age. Improvements in maternal nutritional status are arguably imperative for ensuring an appropriate pregnancy outcome in these vulnerable groups, but ethical boundaries limit these investigations. Experimental paradigms using the pregnant sheep have been widely used to identify the nutritionally sensitive periods of conceptus development. In adult sheep, severe undernutrition during the periconceptual period accelerates maturation of the fetal hypothalamic-pituitary adrenal axis and results in pre-term delivery. Low pre-pregnancy weight, followed by undernutrition during mid-pregnancy, results in reduced placental growth and lower birth weights at term. Studies that have restricted nutrients during mid-gestation only reveal variable effects on the placental and fetal growth trajectory, however if undernutrition is prolonged during late-pregnancy, fetal growth is compromised, particularly in twin pregnancies. In contrast, overnourishing the adolescent sheep to promote rapid maternal growth, results in the premature delivery of low birth weight lambs. These effects are mediated by impaired placental growth, uteroplacental blood flows and fetal nutrient uptakes. At the other end of the nutritional spectrum, undernourishing the adolescent sheep to gradually deplete nutrient reserves, results in fetal growth restriction which is independent of alterations in placental mass.

Behavioral problems and cognitive performance at 5 years of age after very preterm birth: the EPIPAGE Study

OBJECTIVES

We compared the frequency of behavioral problems in very preterm and term children at 5 years of age. We hypothesized that behavioral problems would be associated with cognitive impairment and environmental factors and that differences between the 2 groups would be reduced but persist after adjusting for cognitive performance and environmental factors.

PATIENTS AND METHODS

The Etude Epidémiologique sur les Petits Ages Gestationnels (EPIPAGE) study was a prospective population-based cohort study that included all births occurring between 22 and 32 weeks' gestation and a control group of infants born at 39 to 40 weeks' gestation in 1997 in 9 French regions. Neonatal and obstetrics data were collected at birth. At 5 years of age, sociodemographic status and neurodevelopmental and cognitive development of the children, as well as maternal mental well-being, were assessed. The behavioral problems of 1102 very preterm and 375 term singletons without major impairments were studied by using the parent-completed Strengths and Difficulties Questionnaire.

RESULTS

Parents of very preterm children reported significantly more behavioral problems, with a twofold higher prevalence compared with term children for hyperactivity/inattention, emotional symptoms, and peer problems. Behavioral problems were associated with low cognitive performance, developmental delay, hospitalizations of the child, young maternal age, and poor maternal mental well-being. Very preterm children were still at higher risk of behavioral problems compared with term children after adjustment for cognitive performance and all others factors.

CONCLUSIONS

Behavioral problems were strongly related to cognitive impairment, but very preterm children were still at higher risk even after adjusting for cognitive performance. Early screening for behavioral problems should be encouraged for all very preterm children, and maternal well-being should also be the focus of special attention.

Patterns of distress in African-American mothers of preterm infants

OBJECTIVE

To examine inter-relationships among stress due to infant appearance and behavior in the neonatal intensive care unit (NICU), parental role alteration stress in the NICU, depressive symptoms, state anxiety, posttraumatic stress symptoms, and daily hassles exhibited by African-American mothers of preterm infants and to determine whether there were subgroups of mothers based on patterns of psychological distress.

METHOD

One hundred seventy-seven African-American mothers completed questionnaires on their psychological distress at enrollment during infant hospitalization and 2, 6, 12, 18, and 24 months after term.

RESULTS

Psychological distress measures were intercorrelated. There were four latent classes of mothers: the low distress class with low scores on all measures; the high NICU-related stress class with high infant appearance and parental role stress and moderate scores on other measures; the high depressive symptoms class with high depressive symptoms and state anxiety and moderately elevated scores on NICU-related stress and posttraumatic stress symptoms; the extreme distress class with the highest means on all measures. Infants in the high stress class were sicker than infants in the other classes. The extreme distress class mothers averaged the lowest educational level. The classes differed on distress measures, worry about the child, and parenting stress through 24 months with the extreme distress class having the highest values.

CONCLUSION

Although different types of maternal psychological distress were substantially related, there were distinct subgroups of mothers that were identifiable in the NICU. Moreover, these subgroups continued to differ on trajectories of distress and on their perceptions of the infants and parenting through 24 months after term.

Early interventions involving parents to improve neurodevelopmental outcomes of premature infants: a meta-analysis

OBJECTIVE

To determine in a systematic review, whether interventions for infant development that involve parents, improve neurodevelopment at 12 months corrected age or older.

STUDY DESIGN

Randomized trials were identified where an infant intervention was aimed to improve development and involved parents of preterms; and long-term neurodevelopment using standardized tests at 12 months (or longer) was reported.

RESULT

Identified studies (n=25) used a variety of interventions including parent education, infant stimulation, home visits or individualized developmental care. Meta-analysis at 12 months (N=2198 infants) found significantly higher mental (N=2198) and physical (N=1319) performance scores favoring the intervention group. At 24 months, the mental (N=1490) performance scores were improved, but physical (N=1025) performance scores were not statistically significant. The improvement in neurodevelopmental outcome was not sustained at 36 months (N=961) and 5 years (N=1017).

CONCLUSION

Positive clinically meaningful effects (>5 points) are seen to an age of 36 months, but are no longer present at 5 years.

Screening for maternal depression in the neonatal ICU

Postpartum depression is common in women with infants in the neonatal ICU. Maternal depression can affect infant health and development adversely. A screening program for depression in the neonatal ICU could identify women who have depressive symptoms and facilitate their referral for follow-up services.

Acute posttraumatic stress symptoms among urban mothers with newborns in the neonatal intensive care unit: a preliminary study

OBJECTIVES

Traumatic stress symptoms from multiple causes are endemic among impoverished women who are also at high risk for delivering infants requiring neonatal intensive care unit (NICU) care, but whether this event itself constitutes a distinct traumatic stress trigger is unknown. Previous research does suggest having an infant in the NICU generates traumatic stress among white middle-class mothers, stress that can impact their infant's behavior and development. This study evaluated the prevalence of acute posttraumatic stress symptoms among low-income mothers of infants admitted to the NICU compared with similar mothers with infants in the well baby nursery (WBN).

METHODS

A total of 59 NICU and 60 WBN mothers were recruited from the Boston Medical Center. Within the first week after birth, all participants were assessed for postpartum acute posttraumatic stress and depression symptoms and asked about lifetime traumatic events before the birth of their baby. The acute posttraumatic stress symptoms were analyzed as a continuous variable and whether they reached the categorical severity criteria for acute stress disorder.

RESULTS

NICU mothers show increased symptoms of acute posttraumatic stress and depression. Twenty-three percent of NICU and 3% of WBN reached severity criteria for acute stress disorder. When controlling for relevant covariates, having a newborn in the NICU had a significant association with the number of mothers' acute posttraumatic stress symptoms not fully explained by their symptoms of depression or prior lifetime history of traumatic events.

CONCLUSIONS

Addressing acute posttraumatic stress symptoms may enhance interventions to help urban families of NICU infants.

Persistent maternal anxiety affects the interaction between mothers and their very low birthweight children at 24 months

BACKGROUND

Parental distress following the birth of a premature infant diminishes the parent's ability to be sensitive to the infant's cues, and this may affect infant developmental outcomes.

AIMS

The present study examined the effects of maternal anxiety during infant hospitalization in the Neonatal Intensive Care Unit (NICU) on the interactive behavior of mothers with their very low birthweight (VLBW) children in toddlerhood.

SUBJECTS

A sample of 56 mothers and their VLBW infants were recruited in the NICU.

STUDY DESIGN

During the infant's NICU stay, mothers completed a self-report measure of trait anxiety. These mothers and their infants were followed when the infants were 24 months corrected age, when mothers and their children were videotaped during free play at home. These videotapes were then coded using the Emotional Availability Scales.

RESULTS

Maternal anxiety was not found to be related to severity of neonatal illness. Maternal anxiety in the NICU was associated with less sensitivity and less structure in interaction with their toddlers at 24 months corrected age, even controlling for maternal education and child birthweight. Children of mothers with higher anxiety scores in the NICU were less likely to involve their mothers in their play at 24 months corrected age.

CONCLUSIONS

Maternal anxiety in the NICU predicted adverse interactive behaviors when the children were 24 months corrected age. Early identification of anxious mothers in the NICU is needed in order to initiate preventive intervention to support the mother-infant relationship.

[Following the high-risk newborn: Why? How? Conducting an early medical-psychosocial consultation during hospitalization]

The usual follow-up of high-risk children concentrates on screening for sequelae of perinatal pathology, required by emergency pediatricians and neonatologists to assess their practices. The objective is to manage pathologies by intervening as early as possible. However, is this classical medical model, i.e., the diagnosis of something pathological and a schedule of consultations planned at specific dates, adapted to the needs of high-risk children and their parents? Beyond screening, the child development consultation at the Rozanoff Early Medico-Social Action Center, set up at the A. Trousseau Hospital in 1985, proposes a consultation in which a neuropediatrician, a physical therapist, a pediatric psychiatrist-psychoanalyst, and a social worker closely collaborate. The care begun during neonatal hospitalization concentrates on the needs of the child and parents, with a primary objective of lending support to child-parent interaction. The observation of a child born at 26 GW presenting gaze avoidance concurrent with symptoms of depression in the mother exemplifies the importance of this visit. Why are there still so few of this type of consultation taking into account the medical, psychological, and social risks in a single visit? Why is the attention given to neurologic problems, for which there is currently no cure, so disproportionate to the lack of awareness of the psychological and social risks for which effective prevention and treatment possibilities do exist?

NEURODEVELOPMENTAL IMPAIRMENT: PREDICTORS OF ITS IMPACT ON THE FAMILIES OF EXTREMELY LOW BIRTH WEIGHT INFANTS AT 18 MONTHS

Effects on a family of a child with chronic illness have been described. The Impact on Family Scale (IOF) was developed to measure these effects. The impact of extremely low birth weight (ELBW) infants with neurodevelopmental impairment on families is unknown. This study determined IOF scores for families of ELBW infants with increasing degree of impairment at 18 months and identified factors that increase vulnerability to impact. A total of 3,849 ELBW infant survivors born at the 16 centers of the National Institute of Child Health and Human Development Neonatal Research Network between January 1993 and February 2001 were assessed at 18 to 22 months. Infants were divided into four groups by degree of impairment. IOF scores were analyzed by impairment group. Multivariate analyses assessed effects of impairment, social/demographic factors, unmet service needs, and resource utilization on the IOF. A total of 1,624 (42.2%) infants had moderate/severe impairment. Increasing severity of impairment was associated with higher IOF scores. Severity of impairment contributed 6% of variance to the IOF scores. Twenty-one percent of variance was contributed by additional medical needs, low socioeconomic status (SES), and lack of social support. Although increasing severity of impairment impacts families of ELBW infants, significantly more impact is contributed by additional medical needs, low SES, and lack of social support.

Implementation and evaluation of an individualized developmental care program in a neonatal intensive care unit

PURPOSE

This study aims to detect differences in outcomes for very preterm infants after the introduction of developmental care in a neonatal nursery, and to evaluate the effect of developmental care on parental well-being.

DESIGN AND METHODS

Prospective before and after cohort study of very preterm babies, with education for all staff between cohorts.

RESULTS

No significant differences were found between cohorts for short-term outcomes for babies or parental anxiety levels or depression. All infants scored within normal temperament ranges at 4 months.

PRACTICE IMPLICATIONS

Developmental care is a safe practice model. The interdisciplinary study facilitated professional development and increased the knowledge of nurses.

Assessing the feasibility and acceptability of an intervention to reduce anxiety and enhance sensitivity among mothers of very low birth-weight infants

PURPOSE

A pilot study was conducted to assess the feasibility and acceptability of an intervention program for mothers of very low birth-weight infants in the neonatal intensive care unit (NICU).

SUBJECTS

Thirty-three mothers of infants born weighing less than 1500 g.

DESIGN

A single-group, pretest-posttest design was used.

METHODS

Preintervention mothers completed self-report questionnaires and their interaction with their infant was observed. Mothers then received the intervention program. Mothers were assessed twice postintervention, first when the infant was 1/2 months old and again at 6 months. At the postintervention assessments, mothers completed the same questionnaires and interaction was observed.

MAIN OUTCOME MEASURES

Mothers completed the State-Trait Anxiety Inventory, the revised Parental Stress Scale: Neonatal Intensive Care Unit, the NICU Parental Beliefs Scale, and the Perinatal PTSD Questionnaire. Interactions between mothers and infants were rated by trained research staff using the Index of Parental Behaviour in the NICU. Postintervention mothers also responded to a questionnaire that assessed their perceptions of the intervention program.

RESULTS

It was feasible to enroll mothers because 62% of eligible mothers agreed to participate. However, 39% of mothers who enrolled withdrew. Most of the mothers who withdrew did so before even beginning the intervention, and many of these women were mothers of multiples. It was also feasible to provide the intervention because more than 80% of mothers who began the intervention received all 6 teaching sessions. Mothers found both the content and the format of the program to be acceptable. There were nonetheless several challenges in conducting an intervention study with mothers early in the NICU hospitalization.

CONCLUSIONS

The results of this pilot study are encouraging. It was found to be both feasible and acceptable to provide the intervention program to mothers during the NICU hospitalization. The effectiveness of this program needs to be assessed in a randomized controlled trial.

The Cues and Care Trial: a randomized controlled trial of an intervention to reduce maternal anxiety and improve developmental outcomes in very low birthweight infants

BACKGROUND

Very low birthweight infants are at risk for deficits in cognitive and language development, as well as attention and behaviour problems. Maternal sensitive behaviour (i.e. awareness of infant cues and appropriate responsiveness to those cues) in interaction with her very low birthweight infant is associated with better outcomes in these domains; however, maternal anxiety interferes with the mother's ability to interact sensitively with her very low birthweight infant. There is a need for brief, cost-effective and timely interventions that address both maternal psychological distress and interactive behaviour. The Cues and Care trial is a randomized controlled trial of an intervention designed to reduce maternal anxiety and promote sensitive interaction in mothers of very low birthweight infants.

METHODS AND DESIGN

Mothers of singleton infants born at weights below 1500 g are recruited in the neonatal intensive care units of 2 tertiary care hospitals, and are randomly assigned to the experimental (Cues) intervention or to an attention control (Care) condition. The Cues intervention teaches mothers to attend to their own physiological, cognitive, and emotional cues that signal anxiety and worry, and to use cognitive-behavioural strategies to reduce distress. Mothers are also taught to understand infant cues and to respond sensitively to those cues. Mothers in the Care group receive general information about infant care. Both groups have 6 contacts with a trained intervener; 5 of the 6 sessions take place during the infant's hospitalization, and the sixth contact occurs after discharge, in the participant mother's home. The primary outcome is maternal symptoms of anxiety, assessed via self-report questionnaire immediately post-intervention. Secondary outcomes include maternal sensitive behaviour, maternal symptoms of posttraumatic stress, and infant development at 6 months corrected age.

DISCUSSION

The Cues and Care trial will provide important information on the efficacy of a brief, skills-based intervention to reduce anxiety and increase sensitivity in mothers of very low birthweight infants. A brief intervention of this nature may be more readily implemented as part of standard neonatal intensive care than broad-based, multi-component interventions. By intervening early, we aim to optimize developmental outcomes in these high risk infants.

Stress in mothers of preterm infants in Bangladesh: associations with family, child and maternal factors and children's neuro-development

BACKGROUND

The aim of this paper was to ascertain stress experienced by mothers of prospectively followed up preterm infants, and associations with family, child and maternal factors and children's neuro-development.

METHODS

Within a follow-up study of preterm infants<33 weeks gestational age at a Child Development Center in Dhaka Shishu Hospital, mothers were interviewed with the Self-Report Questionnaire (SRQ) at each visit. Association between SRQ scores and child, family and maternal variables at first and final visit and children's neuro-developmental outcomes was determined.

RESULTS

Low income mothers were more compliant (54%) compared with the defaulters (31%) (P=0.0001) among the 159 mothers enrolled. Of the 88 mothers who were followed up until a mean age of 22 months of their child, 29.3% were at high risk for psychiatric morbidity at first visit compared with 23.9% on their last visit. Use of abortifacients (P=0.026) and higher maternal age (P=0.040) were significantly associated with maternal stress at first visit; while at last follow-up, total number of visits had the most significant association (P=0.041). Twenty-five per cent and 19% of mothers were at risk for psychiatric morbidity in children developing normally and those with neuro-developmental impairments respectively.

CONCLUSIONS

Mothers at risk for psychiatric morbidity can be helped through follow-up support within public hospitals close to their homes, which is most availed by low income families. Neuro-developmental monitoring of high-risk infants closer to homes may be more feasible in resource poor countries than reliance on hospital visits, which increase stress. Biological markers of stress and coping strategies need further research.

Permissive hypercapnia and risk for brain injury and developmental impairment

OBJECTIVE

Permissive hypercapnia is a respiratory-care strategy that is used to reduce the risk for lung injury. The goal of this study was to evaluate whether permissive hypercapnia is associated with higher risk for intraventricular hemorrhage and early childhood behavioral and functional problems than normocapnia among very low birth weight infants.

METHODS

Very low birth weight infants from a statewide cohort were eligible for this study when they were born at <32 weeks' gestational age and survived at least 24 hours. Infants were classified as receiving a permissive hypercapnia, normocapnia, or unclassifiable respiratory strategy during the first 24 hours after birth according to an algorithm based on Pco(2) values and respiratory-treatment decisions that were abstracted from medical charts. Intraventricular hemorrhage diagnosis was also abstracted from the medical chart. Behavioral and functional outcomes were assessed by parent interview at 2 to 3 years. Logistic regression was used to evaluate the relationship between intraventricular hemorrhage and respiratory strategy; ordinary linear regression was used to evaluate differences in behavior and function scores between children by respiratory strategy.

RESULTS

Infants who received a permissive hypercapnia strategy were not more likely to have intraventricular hemorrhage than those with normocapnia. There were no differences in any of the behavioral or functional scores among children according to respiratory strategy. There was a significant interaction between care strategy and 1-minute Apgar score, indicating that infants with lower Apgar scores may be at higher risk for intraventricular hemorrhage with permissive hypercapnia.

CONCLUSIONS

This study suggests that permissive hypercapnia does not increase risk for brain injury and impairment among very low birth weight children. The interaction between respiratory strategy and Apgar score is a potential worrisome exception to this conclusion. Future research should further evaluate the effect of elevated Pco(2) levels among those who are sickest at birth.

Quality of life of caregivers of very low-birthweight infants

BACKGROUND

The health and developmental outcomes of very low-birthweight infants are unpredictable over the first year of life. This uncertainty may have meaningful consequences for parents' quality of life. The objective of this study was to explore the quality of life of caregivers of these infants.

METHODS

Primary caregivers of very low-birthweight infants, 12 to 18 months old, who had been cared for in an inner-city hospital were enrolled in the study. Primary caregivers of full-term infants of the same age served as a comparison group. During a telephone survey, participants answered questions about their quality of life, mental and physical health, living arrangements, and child's health.

RESULTS

Eighty-three caregivers of very low-birthweight infants and 84 caregivers of full-term infants were enrolled in the study. Demographic characteristics of the caregivers were similar between the groups. Forty-five percent of caregivers of very low-birthweight infants reported that their child had an ongoing medical problem compared with 23 percent of caregivers of full-term infants. Both groups of caregivers reported significant physical and mental health problems. Caregivers of very low-birthweight infants reported higher quality of life than did caregivers of full-term infants, but the difference did not reach statistical significance.

CONCLUSIONS

Although very low-birthweight infants had poorer health and required significantly more health care resources than full-term infants, caregivers' quality of life did not differ between the two groups. Caregivers of both groups of infants reported substantial mental and physical health problems but perceived good quality of life. These data will aid parents, physicians, and policy makers as they struggle to make decisions concerning care of high-risk, costly, very low-birthweight infants.

The association of prenatal cocaine use and childhood trauma with psychological symptoms over 6 years

The use of cocaine and other drugs during pregnancy may have serious public health consequences. The objective of this study was to determine if the use of cocaine prenatally identifies women for ongoing risk of psychological symptoms. Four hundred and two women (207 cocaine using [C], 195 non-cocaine using [NC]) were assessed for rates of clinically elevated psychological symptoms shortly after childbirth, 6.5 months and 1, 2, 4 and 6 years after using the Brief Symptom Inventory (BSI). Generalized estimating equation modeling (GEE) was used to compare psychological symptom severity, controlling for confounding factors including early childhood trauma. Results indicated that women identified as having used cocaine during pregnancy had clinically elevated psychological distress (OR = 1.76, 95%CI = 1.15-2.71, p = 0.01), psychoticism (OR = 1.97, 95%CI = 1.41-2.76, p = 0.001), interpersonal sensitivity (OR = 2.34; 95%CI = 1.65-3.34; p < 0.0001) and phobic anxiety (OR = 1.86; 95%CI = 1.24-2.79) across all assessments compared to NC women. Childhood emotional abuse was also independently associated with psychological distress. Women who use cocaine during pregnancy should be recognized as at very high risk of ongoing clinically elevated psychological symptoms and should receive early and regular assessments and intervention for mental health and substance use problems.

Maternal depression is associated with mother-infant interaction in preterm infants

AIM

The purpose of this study was to assess the prevalence and the background factors of maternal depressive symptoms and their relation to the quality of mother-infant interaction in a group of preterm infants and their mothers.

METHODS

The signs of maternal depression were evaluated in 125 mothers of very preterm infants (birth weight < or = 1500 g or < 32 gestational weeks) at 6 months of infant's corrected age using Edinburgh Postnatal Depression Scale (EPDS). The association between maternal depressive symptoms and the quality of mother-infant interaction as assessed by the parent child early relational assessment method (PCERA) method was studied at 6 and 12 months of corrected age in 32 preterm infants who were their mothers' firstborn infants and singletons.

RESULTS

The prevalence of depression assessed by EPDS in mothers of very preterm infants was 12.6%. Most interestingly, the number of postnatal signs of depression associated negatively with the quality of the maternal interaction behaviour with their preterm infants.

CONCLUSIONS

This study suggests that maternal depression may be a risk factor in the development of the mother-infant relationship between preterm infants and their mothers. Therefore, it would be important to identify signs of depression in mothers of preterm infants to offer early support.

Developmental origins theory from prematurity to adult disease

Developmental Origins Theory has received little coverage in the nursing literature, even though it has received much attention in other sciences. The theory proposes that prenatal stress provokes adaptive changes in endocrine and metabolic processes that become permanently programmed and impact later adult health. This paper reviews the theory and describes the primary neuroendocrine mechanism of hypothalamic-pituitary-adrenal axis function. Supporting research evidence in preterm infant and adult samples is presented. Through knowledge of the theory and the long-term sequelae for preterm infants, nurses will have a different theoretical perspective and growing evidence to consider in their care for pregnant women and infants.

Psychosocial and behavioral factors related to the post-partum placements of infants born to cocaine-using women

OBJECTIVE

One objective was to determine if cocaine-using women who did not maintain infant custody (NMC) would report more psychological distress, domestic violence, negative coping skills, lower social support and more childhood trauma than cocaine-using women who maintained custody (MC) of their infant. A second objective was to evaluate the relative contribution of psychosocial factors to infant placement.

METHODS

Psychosocial profiles of MC women (n=144) were compared with NMC (n=66) cocaine-using women. Subjects were low income, urban, African-American women who delivered an infant at a county teaching hospital. The Brief Symptom Inventory (BSI), an assessment of coping strategies (COPE), Multidimensional Scale of Perceived Social Support (MSPSS), Conflict Tactics Scale (CTS) and Childhood Trauma Questionnaire (CTQ) were administered. The associations of infant placement status to demographic factors, drug use and psychosocial measures were evaluated.

RESULTS

The NMC group reported greater overall psychological distress, psychoticism, somatization, anxiety and hostility than the MC group. The NMC group had more childhood neglect and physical abuse and used more negative coping strategies than the MC group. Lack of prenatal care [OR=.83, CI (.75-.91), p<.0001], heavier prenatal cocaine use [OR=2.55, CI (1.13-4.34), p<.007], greater psychological distress [OR=2.21, CI (1.13-4.34), p<.02] and a childhood history of emotional neglect [OR=1.10, CI (1.02-1.19), p<.02] were associated with increased likelihood of loss of infant custody after control for other substance use and demographic variables.

CONCLUSIONS

NMC women have more negative psychological and behavioral functioning post-partum than MC women. Less prenatal care and greater cocaine use, psychological distress and maternal childhood emotional neglect are associated with the post-partum placement of infants born to cocaine-using women.

PRACTICE IMPLICATIONS

Results of this study indicate that poor, urban women who use cocaine prenatally display several measurable differences on psychosocial and behavioral risk factors based on child placement status. Among these risk factors heavier cocaine use, lack of prenatal care, more severe psychological symptoms and early childhood experiences of emotional neglect increase the likelihood of loss of infant custody. Routine, objective assessments of psychosocial and behavioral characteristics of women who use cocaine during pregnancy can aid Child Protective Service workers and clinicians by providing baseline data from which to tailor interventions and set improvement criteria for mother-child reunification.

Parents' mental health after the birth of an extremely preterm child: a comparison between bereaved and non-bereaved parents

OBJECTIVE

To assess the impact of extremely preterm birth (24-26 weeks of gestation) on the mental health of parents two to six years after delivery, and to examine potential differences in post-traumatic growth between parents whose newborn infant died and those whose child survived.

METHOD

A total of 54 parents who had lost their newborn and 38 parents whose preterm child survived were assessed by questionnaires with regard to depression and anxiety (HADS) and post-traumatic growth (PTGI).

RESULTS

Neither group of parents had clinically relevant levels of depression and anxiety. Mothers showed higher levels of anxiety than fathers. Bereaved parents with no other, living child reported higher levels of depression than bereaved parents with one or more children. Mothers reported higher post-traumatic growth compared to fathers. In particular, bereaved mothers experienced the value and quality of their close social relationships more positively compared to the non-bereaved parents.

CONCLUSION

In the long term, bereaved and non-bereaved parents cope reasonably well with an extremely preterm birth of a child. Post-traumatic growth appears to be positively related to bereavement, particularly in mothers.

An overview of mortality and sequelae of preterm birth from infancy to adulthood

Survival rates have greatly improved in recent years for infants of borderline viability; however, these infants remain at risk of developing a wide array of complications, not only in the neonatal unit, but also in the long term. Morbidity is inversely related to gestational age; however, there is no gestational age, including term, that is wholly exempt. Neurodevelopmental disabilities and recurrent health problems take a toll in early childhood. Subsequently hidden disabilities such as school difficulties and behavioural problems become apparent and persist into adolescence. Reassuringly, however, most children born very preterm adjust remarkably well during their transition into adulthood. Because mortality rates have fallen, the focus for perinatal interventions is to develop strategies to reduce long-term morbidity, especially the prevention of brain injury and abnormal brain development. In addition, follow-up to middle age and beyond is warranted to identify the risks, especially for cardiovascular and metabolic disorders that are likely to be experienced by preterm survivors.

Parent preferences for motor development education in the neonatal intensive care unit

PURPOSE

The purpose of this pilot study was to determine parents' preferred method of receiving education on motor development of infants born preterm.

METHODS

This study was conducted through a pair of focus groups in which parents evaluated different educational formats and provided feedback on the clarity of the parent education intervention.

RESULTS

Parents reported that they would prefer to learn about their infant's motor development with a combination of observation, discussion, and written material. After the parent education intervention, parents of infants born preterm were able to describe the ways they would play with their infant and answered more questions correctly on a postintervention test.

CONCLUSIONS

Parents of infants who were born preterm would benefit from education using multiple approaches. The parent education intervention developed in this study is clear and well understood by parents. Further research is needed to evaluate the efficacy of this intervention.

Clinical data predict neurodevelopmental outcome better than head ultrasound in extremely low birth weight infants

OBJECTIVE

To determine the relative contribution of clinical data versus head ultrasound scanning (HUS) in predicting neurodevelopmental impairment (NDI) in extremely low birth weight infants.

STUDY DESIGN

A total of 2103 extremely low birth weight infants (<1000 g) admitted to a National Institute of Child Health and Human Development Neonatal Research Network center who underwent HUS within the first 28 days, a repeat one around 36 weeks' postmenstrual age, and neurodevelopmental assessment at 18 to 22 months corrected age were selected. Multivariate logistic regression models were developed with clinical or HUS variables. The primary outcome was the predictive abilities of the HUS performed before 28 days after birth and closer to 36 weeks postmenstrual age, either alone or in combination with "Early" and "Late" clinical variables.

RESULTS

Models with clinical variables alone predicted NDI better than models with only HUS variables at both 28 days and 36 weeks (both P < .001), and the addition of the HUS data did not improve prediction. NDI was absent in 30% and 28% of the infants with grade IV intracranial hemorrhage or periventricular leukomalacia, respectively, but was present in 39% of the infants with a normal HUS result.

CONCLUSIONS

Clinical models were better than HUS models in predicting neurodevelopment.

Randomised trial of a parenting intervention during neonatal intensive care

OBJECTIVE

To evaluate the influence of parenting intervention on maternal responsiveness and infant neurobehavioural development following a very premature birth.

DESIGN

Cluster-randomised controlled trial, with a crossover design and three-month washout period.

SETTING

Six neonatal intensive care units.

PATIENTS

Infants born <32 weeks' gestation.

INTERVENTION

The Parent Baby Interaction Programme (PBIP) is a supportive, educational intervention delivered by research nurses in the neonatal intensive care unit, with optional home follow-up for up to six weeks after discharge.

MAIN OUTCOME MEASURES

Parenting stress at 3 months adjusted age, as measured by the Parenting Stress Index (PSI). Other outcomes included the Neurobehavioural Assessment of the Preterm Infant (NAPI) and maternal interaction as assessed by the Nursing Child Assessment Teaching Scale (NCATS) and the responsivity subscale for Home Observation for Measurement of the Environment (HOME).

RESULTS

112 infants were recruited in the intervention phases and 121 in the control phases. Mean standardised NAPI scores at 35 weeks did not differ between the PBIP and control groups. Both groups had low but similar NCATS caregiver scores before discharge (36.6 in the PBIP group and 37.4 in control, adjusted mean difference -0.7, 95% CI -2.7 to 1.4). At three months, adjusted age mean PSI scores for the PBIP group were 71.9 compared with 67.1 for controls (adjusted mean difference 3.8, 95% CI -4.7 to 12.4). NCATS scores and HOME responsivity scores were similarly distributed between the groups.

CONCLUSION

This early, nurse-delivered, parent-focused interaction programme intervention had no measurable effects on short-term infant neurobehavioural function, mother-child interaction or parenting stresses.

Parenting very low birth weight children at school age: maternal stress and coping

OBJECTIVE

To compare severity and determinants of stress and coping in mothers of 8-year-old very low birth weight (VLBW) and term children varying in medical and developmental risk.

STUDY DESIGN

Three groups of mothers/infants were prospectively compared in a longitudinal study from birth to 8 years (110 high-risk VLBW, 80 low-risk VLBW, and 112 term). Maternal psychological distress, coping, parenting/marital stress, child health, and family impact were measured in the children at age 8 years.

RESULTS

Mothers of VLBW children differed from term mothers, reporting less consensus with partners, more concern for their children's health, less parent-child conflict, and fewer years of education attained. Mothers of high-risk VLBW children experienced the greatest family and personal strains and used less denial and disengagement coping. The groups exhibited no differences in the sense of parenting competence, divorce rate, parenting/marital satisfaction, family cohesion, and psychological distress symptoms. Multiple birth, low socioeconomic status, and lower child IQ added to maternal stress.

CONCLUSIONS

VLBW birth has long-term negative and positive impacts on maternal/family outcomes related to the infant's medical risk.

Parental experiences during the first period at the neonatal unit after two developmental care interventions

AIM

Developmental care has gained increased attention in the individualized care for preterm infants. This study was designed to explore the effect of a basic form of developmental care and the more extended Newborn Individualized Developmental Care and Assessment Program (NIDCAP) on parental stress, confidence and perceived nursing support.

METHODS

Two consecutive randomized controlled trials (RCT's) comparing (1) standard care versus basic developmental care (standardized nests and incubator covers) (n = 133) and (2) basic developmental care versus NIDCAP, including behavioural observations (n = 150). Parents of infants born <32 weeks gestational age (GA) received questionnaires after the first week of admission in the neonatal unit and on average these 2 weeks after the birth of their infant.

RESULTS

No significant differences were found in confidence, perceived nursing support or parental stress. The difference in parental stress between mother and father was less in the NIDCAP intervention group (p = .03), although not significant.

CONCLUSION

Both basic developmental care and NIDCAP had little effect on parental experiences during the first period at the neonatal unit. As a result of increased paternal stress, the NIDCAP intervention tended to decrease the difference in parental stress levels of fathers and mothers, possibly because of the increased involvement of father during the NIDCAP intervention.

The conceptual structure of transition to motherhood in the neonatal intensive care unit

AIM

This paper is a report of a concept analysis of transition to motherhood for mothers with infants in a neonatal intensive care unit.

BACKGROUND

Mothers with infants in a neonatal intensive care unit have more difficulty in their transition to motherhood compared with mothers of healthy infants. The concept of transition to motherhood in the neonatal intensive care unit is not well-understood in nursing, often being confused with mothers' psychological responses in the neonatal intensive care unit.

METHODS

The concept analysis combined Rodgers' evolutionary method with Schwartz-Barcott & Kim's Hybrid method. Thirty-eight studies were reviewed and a purposive sample of 10 Korean mothers with infants in a neonatal intensive care unit was interviewed.

FINDINGS

Three critical attributes of transition to motherhood in the neonatal intensive care unit were identified: (1) time-dependent process, (2) psycho-emotional swirling and (3) hovering around the edge of mothering. These are caused by the antecedents (1) unexpected outcome of pregnancy, (2) awareness of the situation and (3) mother-infant separation. The consequences were: (1) delayed motherhood and (2) developing a sense of meaning concerning family and life. Additionally, five influencing factors to be alleviated were identified: (1) negative meaning attribution, (2) uncertainty, (3) social prejudice, (4) lack of opportunities to make contact with the infant and (5) the neonatal intensive care unit environment.

CONCLUSIONS

This concept analysis should help nurses to understand the process of becoming a mother in a neonatal intensive care unit and plan appropriate interventions for mothers with special needs.

Infants admitted to a neonatal intensive care unit: parental psychological status at 9 months

AIM

This paper reports on the 9-month follow-up of parents who had an infant admitted to neonatal intensive care unit (NICU) compared to parents of full-term health infants. The psychological status of the parent groups is compared and factors associated with status change are examined.

METHODS

Prospective longitudinal study of random sample of 447 parents (mother and father with an infant admitted to the NICU and 189 parents (mother and father) with term infant not requiring NICU admission. Parents' depression and anxiety symptoms were assessed at infant birth and 9 months later.

RESULTS

The increased levels of depression and anxiety symptoms evident in NICU parents after their infant's birth were no longer apparent by 9 months. Higher initial symptom severity and perceived quality of the couple relationship were most commonly associated with improvement. Other factors related to symptoms change were number of baby hospitalizations for fathers and being in the NICU, age and living with the infant's father or mother.

CONCLUSION

For the majority of parents having an infant admitted to the NICU does not result in ongoing psychological distress.

Feeding outcomes of extremely premature infants after neonatal care

Feeding is a primary concern for families of extremely preterm (EP) infants following discharge from neonatal care. An increasing number of EP children are being referred for treatment of feeding problems, including eating only a few types of food or very small portions, difficulty transitioning to textured foods, and refusing food. These issues have the potential for significant consequences for the children's growth and development as well as their family's well-being. An understanding of the kinds of feeding problems faced by families of EP infants can help nurses guide families to be ready for and respond to these issues. In this article, the evidence for and the nature of feeding problems in EP children after discharge from neonatal care are examined.

Measuring Japanese mothers' perception of child abuse: development of a Japanese version of the child abuse blame scale--physical abuse (CABS-PA-J)

BACKGROUND

The Child Abuse Blame Scale - Physical Abuse (CABS-PA) was translated into Japanese and its subscale items modified by the authors according to the Japanese cultural context. The aim of the current study was to investigate the appropriateness, reliability, and clinical applicability of the CABS-PA Japanese version (CABS-PA-J). Modifications were made to enable the determination of child abuse recognition in a Japanese cultural setting and early clinical intervention in child abuse cases.

METHODS

The CABS-PA text was translated into Japanese, then back translated. The appropriateness of scale item translations was verified based on e-mail discussions with the original CABS-PA author. Exploratory and confirmatory factor analyses were performed to examine the validity of CABS-PA-J responses and to confirm the validity of factor structure. Criterion-related validity was also confirmed. The Japanese scale was used to examine the characteristic differences between mothers of premature infants (< 1500 g) and those of other infants (>or= 1500 g).

RESULTS

Exploratory and confirmatory factor analyses found the factor structure to be similar between the original scale and the translated CABS-PA-J, suggesting adequate factor validity. There was a statistically significant correlation between social support from a spouse or third party and the abuse score on a subscale, partially demonstrating criterion-referenced validity. Similarities and differences were found in the stress reactions of the mothers of premature infants (< 1500 g) and those of other infants (>or= 1500 g).

CONCLUSION

CABS-PA-J was shown to be appropriate and reliable. It is an effective tool for determining the recognition of child abuse among Japanese mothers.
