Markkula A, Pyhälä-Neuvonen R, Stolt S. Interventions and their efficacy in supporting language development among preterm children aged 0-3 years - A systematic review. Early Hum Dev 2024; 195:106057. [PMID: 38901388 DOI: 10.1016/j.earlhumdev.2024.106057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 05/26/2024] [Accepted: 06/03/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND Preterm children have a higher risk for linguistic delays than full-term infants but are rarely provided with language intervention at an early age. Knowledge on early language interventions targeted to preterm children is scarce, and efficacy of the interventions is rarely reported. AIM This systematic review aims to identify interventions for preterm children aged 0-3 years with at least one language outcome. Efficacy of the interventions and quality of the study reports were evaluated. STUDY DESIGN The article search was carried out in six databases: EBSCOhost, Scopus, ERIC, LLBA, Ovid, and Web of Science. Effect sizes (Hedges' g) were calculated for language outcomes. Quality of the study reports was assessed using the levels of evidence system by the American Speech-Language-Hearing Association. RESULTS The 28 studies identified were divided into three groups: interventions at Neonatal Intensive Care Unit, interventions during the first year, and interventions during the second and/or third years. Most of the interventions focused on supporting child-care and general development. Of the interventions, 61 % were efficacious in supporting language development of preterm children. The most promising results regarding efficacy were interventions conducted during the second and/or third years (80 %). Quality of the reports varied from high/good (89 %) to low (11 %). CONCLUSION The 28 existing studies provide limited evidence of the efficacy of very early interventions promoting language development of preterm children. However, especially the results for interventions conducted during the second and/or third years show promise. More studies, particularly language-focused interventions with longer follow-ups, are needed.

Abstract
BACKGROUND Infants born preterm are at increased risk of cognitive and motor impairments compared with infants born at term. Early developmental interventions for preterm infants are targeted at the infant or the parent-infant relationship, or both, and may focus on different aspects of early development. They aim to improve developmental outcomes for these infants, but the long-term benefits remain unclear. This is an update of a Cochrane review first published in 2007 and updated in 2012 and 2015. OBJECTIVES Primary objective To assess the effect of early developmental interventions compared with standard care in prevention of motor or cognitive impairment for preterm infants in infancy (zero to < three years), preschool age (three to < five years), and school age (five to < 18 years). Secondary objective To assess the effect of early developmental interventions compared with standard care on motor or cognitive impairment for subgroups of preterm infants, including groups based on gestational age, birthweight, brain injury, timing or focus of intervention and study quality. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and trial registries in July 2023. We cross-referenced relevant literature, including identified trials and existing review articles. SELECTION CRITERIA Studies included randomised, quasi-randomised controlled trials (RCTs) or cluster-randomised trials of early developmental intervention programmes that began within the first 12 months of life for infants born before 37 weeks' gestational age (GA). Interventions could commence as an inpatient but had to include a post discharge component for inclusion in this review. Outcome measures were not prespecified, other than that they had to assess cognitive outcomes, motor outcomes or both. The control groups in the studies could receive standard care that would normally be provided. DATA COLLECTION AND ANALYSIS Data were extracted from the included studies regarding study and participant characteristics, timing and focus of interventions and cognitive and motor outcomes. Meta-analysis using RevMan was carried out to determine the effects of early developmental interventions at each age range: infancy (zero to < three years), preschool age (three to < five years) and school age (five to < 18 years) on cognitive and motor outcomes. Subgroup analyses focused on GA, birthweight, brain injury, time of commencement of the intervention, focus of the intervention and study quality. We used standard methodological procedures expected by Cochrane to collect data and evaluate bias. We used the GRADE approach to assess the certainty of evidence. MAIN RESULTS Forty-four studies met the inclusion criteria (5051 randomly assigned participants). There were 19 new studies identified in this update (600 participants) and a further 17 studies awaiting outcomes. Three previously included studies had new data. There was variability in the focus and intensity of the interventions, participant characteristics, and length of follow-up. All included studies were either single or multicentre trials and the number of participants varied from fewer than 20 to up to 915 in one study. The trials included in this review were mainly undertaken in middle- or high-income countries. The majority of studies commenced in the hospital, with fewer commencing once the infant was home. The focus of the intervention programmes for new included studies was increasingly targeted at both the infant and the parent-infant relationship. The intensity and dosages of interventions varied between studies, which is important when considering the applicability of any programme in a clinical setting. Meta-analysis demonstrated that early developmental intervention may improve cognitive outcomes in infancy (developmental quotient (DQ): standardised mean difference (SMD) 0.27 standard deviations (SDs), 95% confidence interval (CI) 0.15 to 0.40; P < 0.001; 25 studies; 3132 participants, low-certainty evidence), and improves cognitive outcomes at preschool age (intelligence quotient (IQ); SMD 0.39 SD, 95% CI 0.29 to 0.50; P < 0.001; 9 studies; 1524 participants, high-certainty evidence). However, early developmental intervention may not improve cognitive outcomes at school age (IQ: SMD 0.16 SD, 95% CI -0.06 to 0.38; P = 0.15; 6 studies; 1453 participants, low-certainty evidence). Heterogeneity between studies for cognitive outcomes in infancy and preschool age was moderate and at school age was substantial. Regarding motor function, meta-analysis of 23 studies showed that early developmental interventions may improve motor outcomes in infancy (motor scale DQ: SMD 0.12 SD, 95% CI 0.04 to 0.19; P = 0.003; 23 studies; 2737 participants, low-certainty evidence). At preschool age, the intervention probably did not improve motor outcomes (motor scale: SMD 0.08 SD, 95% CI -0.16 to 0.32; P = 0.53; 3 studies; 264 participants, moderate-certainty evidence). The evidence at school age for both continuous (motor scale: SMD -0.06 SD, 95% CI -0.31 to 0.18; P = 0.61; three studies; 265 participants, low-certainty evidence) and dichotomous outcome measures (low score on Movement Assessment Battery for Children (ABC) : RR 1.04, 95% CI 0.82 to 1.32; P = 0.74; 3 studies; 413 participants, low-certainty evidence) suggests that intervention may not improve motor outcome. The main source of bias was performance bias, where there was a lack of blinding of participants and personnel, which was unavoidable in this type of intervention study. Other biases in some studies included attrition bias where the outcome data were incomplete, and inadequate allocation concealment or selection bias. The GRADE assessment identified a lower certainty of evidence in the cognitive and motor outcomes at school age. Cognitive outcomes at preschool age demonstrated a high certainty due to more consistency and a larger treatment effect. AUTHORS' CONCLUSIONS Early developmental intervention programmes for preterm infants probably improve cognitive and motor outcomes during infancy (low-certainty evidence) while, at preschool age, intervention is shown to improve cognitive outcomes (high-certainty evidence). Considerable heterogeneity exists between studies due to variations in aspects of the intervention programmes, the population and outcome measures utilised. Further research is needed to determine which types of early developmental interventions are most effective in improving cognitive and motor outcomes, and in particular to discern whether there is a longer-term benefit from these programmes.

Parent-Integrated Interventions to Improve Language Development in Children Born Very Preterm. CHILDREN (BASEL, SWITZERLAND) 2023; 10:953. [PMID: 37371185 DOI: 10.3390/children10060953] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Revised: 05/10/2023] [Accepted: 05/18/2023] [Indexed: 06/29/2023]
Abstract
Neurodevelopmental challenges in children born very preterm are common and not improving. This study tested the feasibility of using Evidence-based Practice to Improve Quality (EPIQ), a proven quality improvement technique that incorporates scientific evidence to target improving language abilities in very preterm populations in 10 Canadian neonatal follow-up programs. Feasibility was defined as at least 70% of sites completing four intervention cycles and 75% of cycles meeting targeted aims. Systematic reviews were reviewed and performed, an online quality improvement educational tool was developed, multidisciplinary teams that included parents were created and trained, and sites provided virtual support to implement and audit locally at least four intervention cycles of approximately 6 months in duration. Eight of ten sites implemented at least four intervention cycles. Of the 48 cycles completed, audits showed 41 (85%) met their aim. Though COVID-19 was a barrier, parent involvement, champions, and institutional support facilitated success. EPIQ is a feasible quality improvement methodology to implement family-integrated evidence-informed interventions to support language interventions in neonatal follow-up programs. Further studies are required to identify potential benefits of service outcomes, patients, and families and to evaluate sustainability.

Impact of Differing Language Background Exposures on Bayley-III Language Assessment in a National Cohort of Children Born Less than 29 Weeks' Gestation. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9071048. [PMID: 35884032 PMCID: PMC9316512 DOI: 10.3390/children9071048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 06/25/2022] [Accepted: 07/09/2022] [Indexed: 11/16/2022]
Abstract
Preterm infants are at risk for adverse neurodevelopmental outcomes, especially language delay. Preterm infants < 29 weeks’ gestational age, cared for in Canadian Neonatal Follow-Up Network affiliated hospitals, were assessed between 18 to 21 months corrected age using the Bayley-III. Bayley-III Language Composite Scores were compared using univariate and multivariate analyses for children in three primary language groups: English, French and other. 6146 children were included. The primary language at home was English, French or another language for 3708 children (60%), 1312 children (21%) and 1126 children (18%), respectively, and overall, 44% were exposed to two or more languages at home. Univariate analysis showed that primary language was associated with lower Bayley-III Language scores; however, multivariate analyses demonstrated that neither primary language nor language of administration were significantly associated with lower language scores when adjusted for gestational age, other developmental delays and sociodemographic factors, but multiple language exposure was. Sociodemographic and other factors are more important in determining language development than primary language at home. Further studies are needed to examine the association between exposure to multiple languages and lower Bayley-III language scores in preterm infants.

A Community-based Responsive Caregiving Program Improves Neurodevelopment in Two-year Old Children in a Middle-Income Country, Grenada, West Indies. PSYCHOSOCIAL INTERVENTION 2022; 31:97-107.

Abstract
Many young children in low- and middle-income countries (LMICs) are at risk of developmental delays. Early child development (ECD) interventions have been shown to improve outcomes, but few interventions have targeted culturally normative violence such as corporal punishment (CP). We partnered with an existing community-based ECD organization in the LMIC of Grenada to implement a parallel controlled-trial single-blind responsive caregiving intervention that educates parents about the developing brain and teaches alternatives to corporal punishment while building parental self-regulation skills and strengthening social-emotional connections between parent and child. Parents and primary caregivers with children under age two were eligible. Allocation to the intervention and waitlist control arms was unblinded and determined by recruitment into the program. Neurodevelopment was assessed by blinded testers when each child turned age two. Primary comparison consisted of neurodevelopmental scores between the intervention and waitlist control groups (Clinicaltrials.gov registration # NCT04697134). Secondary comparison consisted of changes in maternal mental health, home environment, and attitudes towards CP. Children in the intervention group (n = 153) had significantly higher scores than children in the control group (n = 151) on measures of cognition (p = .022), fine motor (p < .0001), gross motor (p = .015), and language development (p = .013). No difference in secondary outcomes, including CP, was detected.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18168670. [PMID: 34444418 PMCID: PMC8391928 DOI: 10.3390/ijerph18168670] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 08/10/2021] [Accepted: 08/14/2021] [Indexed: 11/29/2022]
Abstract
The study was conducted with 104 mothers (average age 32.5 years, SD 6.1) of preterm infants (very and moderately preterm but still healthy) to monitor the perceived maternal role competence from the time of hospitalisation to post-discharge, in order to define an intervention program to support mothers during this transition. A targeted Q-Sort tool (Maternal Competence Q-Sort in preterm birth) was applied at two different times as a self-observation tool for parenting competence in neonatology. A tendency towards dysregulation of the maternal role competence was detected, mainly in terms of low self-assessment and was found to worsen during post-discharge, particularly with regard to caregiving ability. This study suggests the importance of accompanying parenting competence in preterm birth conditions, not only during hospitalisation in the Neonatal Intensive Care Unit (NICU) but also following discharge in order to promote the development of premature infants. This paper reports in the last part a specific integrated psychoeducational intervention program (psychologist and nurses), which we defined precisely in light of the suggestions offered by the study data on perceived maternal competence created with the Q-sort.

Abstract
AIM Early therapy can improve developmental outcomes for preterm infants. However, preterm infants who are referred have low enrolment in early therapy services following neonatal intensive care unit (NICU) discharge. This manuscript aims to investigate the relationship between infant medical and sociodemographic factors and enrolment in early therapy services post-NICU discharge, when system-related barriers to access are minimised. METHODS This was a retrospective investigation of 89 families with infants born ≤32 weeks of gestation. Families were approached for enrolment into early therapy services following NICU discharge through Baby Bridge programming, which aims to improve access to therapy services following NICU discharge. RESULTS Seventy-three (82%) families enrolled in early therapy services, and 16 (18%) families declined. Parents were more likely to enrol in early therapy if they had public insurance (P = 0.01), a maternal psychiatric diagnosis (P = 0.02) or additional children under 18 years in the home (P = 0.01). No infant medical factors were related to enrolment. CONCLUSION Although enrolment rates were high, 18% of families refused therapy services, despite removing system-related barriers to access. Targeted interventions can be developed to increase enrolment in early therapy services among populations who are most likely to refuse therapy services after NICU discharge.

Abstract
Increased survival in the very preterm population results in a higher risk of developing neurodevelopmental and behavioral disabilities among survivors. We examined the outcomes of very preterm infants and parents after a preventive intervention program of four home visits by a specialized nurse, 5 days, 2 weeks, and 1 month after discharge, respectively, and at CA 2 months, followed by up to 12 times of group sessions between CA 3 and 6 months. Our multicenter randomized controlled trial assessed 138 preterm infants (gestational age ≤30 weeks or birth weight ≤1500 g) enrolled from the three participating hospitals. We randomly allocated the preterm babies to either the intervention or the control group. The primary outcome was the neurodevelopmental outcomes of Bayley-III scores at CA 10 and 24 months. At CA 10 months and 24 months, there were no significant differences between the intervention and control groups in the cognitive, motor, and language domains of Bayley-III scores. In addition, there were no significant differences in the mother’s depression scale, mother–child attachment, and the modified Infant and Toddler Social and Emotional Assessment.

Abstract
Interventions are needed to enhance early development and minimise long-term impairments for children born very preterm (VP, <32 weeks' gestation) and their families. Given the role of the environment on the developing brain, the potential for developmental interventions that modify the infant's hospital and home environments to improve outcomes is high. Although early developmental interventions vary widely in focus, timing, and mode of delivery, evidence generally supports the effectiveness of these programs to improve specific outcomes for children born VP and their families. However, little is known about mechanisms for effectiveness, cost- and long-term effectiveness, which programs might work better for whom, and how to provide early intervention services equitably. This information is critical to facilitate systematic integration of effective developmental interventions into clinical care for infants born very preterm and their families.

Abstract
OBJECTIVE To verify whether early intervention focused on the family improves the cognitive, motor, and language development of children born preterm and/or at social risk in the first 3 years of life. SOURCE OF DATA Meta-analysis of clinical trials published between 2008 and 2018, in the following databases: CINAHL, MEDLINE - PubMed, MEDLINE - BVS, LILACS - BVS, IBECS - BVS, PEDro and Cochrane Reviews. Experimental studies on early interventions focused on the family, whose target groups were children born preterm and/or at social risk, with assessment of cognitive and/or motor and/or language development up to 3 years were included. The studies were rated using the PEDro Scale. DATA SYNTHESIS Twelve studies were included from a total of 3378 articles. Early intervention focused on the family contributed to the development of the cognitive (Standardized Mean Difference - SMD=0.48, 95% CI: 0.34-0.61) and motor (SMD=0.76, 95% CI: 0.55-0.96) domains of preterm infants. Regarding cognitive development, performance improvement was observed at 12, 24 and 36 months, while in the motor domain, the effect was observed only at 12 months in preterm infants. There was no benefit of the intervention in the cognitive, motor, and language outcomes of children with the social risk factor associated to biological risk. CONCLUSION Early intervention focused on the family has a positive effect on the cognition of preterm infants. The effect on motor development was lower, possibly due to the emphasis on interventions in family-child interaction. The effect of interventions on the development of children at social risk and on the language domain was inconclusive, due to the scarcity of studies in the area.

Zimmerman E. Do Infants Born Very Premature and Who Have Very Low Birth Weight Catch Up With Their Full Term Peers in Their Language Abilities by Early School Age? JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2018; 61:53-65. [PMID: 29255846 DOI: 10.1044/2017_jslhr-l-16-0150] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2016] [Accepted: 08/03/2017] [Indexed: 06/07/2023]
Abstract
PURPOSE This study examined the extent to which children born preterm (< 37 weeks) and/or who have low birth weight (< 2,500 g) catch up with their full term peers in terms of their language abilities at early school age (≥ 5 to < 9 years). METHOD A systematic literature search identified empirical studies that fit the inclusion criteria. Data from the tests/questionnaires used for meta-analysis spanned the following language categories: total language score, expressive language, receptive language, pragmatics, phonological awareness, and grammar. The means (standard deviations) were extracted from the studies and were converted to mean difference and 95% confidence intervals to test for overall effect. RESULTS Sixteen studies met the inclusionary criteria, for a total of 2,739 participants, of which 1,224 were born full term and 1,515 were born preterm. It is important to note that the preterm cohort represented very preterm infants who have a very low birth weight. The meta-analysis found that preterm infants scored significantly worse on total language (p < .001), receptive language (p < .001), expressive language (p < .001), phonological awareness (p < .001), and grammar (p = .03) than their full term peers. However, preterm infants did not score significantly worse than their peers on their pragmatics (p = .19). CONCLUSIONS Children born VPT and who have VLBW perform worse than their peers on their total language, receptive language, expressive language, phonological awareness, and grammar abilities by early school age. This information is important for speech-language pathologists to consider as children born prematurely reach school age.

Abstract
Infants born preterm are at high risk for the onset of cognitive dysfunctions at school age. The aim of this study was to investigate the association between early neurodevelopmental assessment and the risk of adverse cognitive outcome in extremely low birth weight children. We enrolled all newborns (January 2002 – April 2007) consecutively admitted to our Institution, with a birthweight < 1000 g. Exclusion criteria were genetic abnormalities, severe neurofunctional impairment, and/or neurosensory disabilities. Ninety-nine children were assessed at 1 year of corrected age using the Griffiths Mental Development Scales Revised. The same children were re-assessed at school age through the Wechsler Intelligence Scale for Children. Children with impaired Griffiths General Quotient (i.e., <1 SD) at 1 year of corrected age showed a significantly lower Full Scale Intelligence Quotient at 7 years of chronological age when compared to children who scored in the normal range at 1 year (p < 0.01). Considering the Griffiths Sub-quotients separately, a poor score in the Performance or in the Personal-Social Sub-quotients at 1 year was associated with significantly worse cognitive outcomes both in the Verbal and in the Performance Intelligence Quotients at 7 years (p < 0.01 and p < 0.05, respectively). A score <1 SD in the Locomotor or in the Eye and Hand Coordination Sub-quotients were specifically associated with poorer Performance or Verbal Intelligence Quotients, respectively (p < 0.05). Our findings suggest that a poor score on the Griffiths Scales at 1 year is associated with a higher risk of cognitive impairment at school age. Larger confirmation studies are needed.

Abstract
BACKGROUND Early childhood is a critical stage of development. Inequalities in experiences affect children's wellbeing and determine their development. Early years interventions focusing on children and their parents may help address inequalities during this critical period. Understanding the experiences and perceptions of parents receiving early years programmes and staff providing these may help service development and delivery. The objective of this study was to describe staff and parents' accounts of how early childhood programmes in different European country contexts improved child development. METHODS Five early years programmes were selected using pre-set criteria out of ten proposed ones. Twenty-five individual interviews and six focus groups were carried out with staff running interventions and with users, children and their families in different EU countries. Investigations of the studies were carried out using qualitative research methods. Data were collected by collaborating partner institutions included in the project. RESULTS Participants described programmes which aimed to provide activities to stimulate children's learning through structured play and which provided support and assistance for parents. In these, parents were actively involved in activities. Parents and staff referred to establishing long-term trust based relationships as a key element for programmes to improve parents' self-esteem and reduce their stress levels which in turn helped improve their children's development. CONCLUSIONS Programmes described by staff as being successful, delivered services tailored to parents and their children. Adapting to and understanding the families' circumstances and involving parents was seen by staff as important. Staff also described establishing trust based relationships as a key enabler in programme delivery; their perceptions were that parents should be empowered to develop their own capacities thus strengthening their abilities to assist in their children's learning, which had a positive effect on children.

Abstract
BACKGROUND Parental sensitivity is the interaction process by which parents (a) recognize cues from their infant, (b) interpret these cues adequately, (c) identify an appropriate response and (d) apply this response in an appropriate time frame. In the neonatal intensive care unit, parents of preterm infants often encounter factors hampering the establishment of their parental sensitivity. Parents report the need to be in proximity to and to participate in their preterm infant's care in order to develop their sensitivity to their newborn infant. To do so, the effectiveness of interventions promoting their parental sensitivity has been evaluated with randomized controlled trials. The purpose of this systematic review is to evaluate the effectiveness of early interventions promoting parental sensitivity of preterm infants' parents. METHODS/DESIGN A search will be done in the following databases: CINAHL, PubMed in addition to Medline, Embase, PsycInfo, Web of Science, Scopus and ProQuest. No restriction for the years of publication will be considered. Two experts will be conducting independently each step of the review. All studies of randomized controlled trials of early interventions, for parents of preterm infants, implemented in the neonatal intensive care unit before the infant has reached 37 weeks of corrected gestational age, will be considered eligible. Primary outcome is parental sensitivity. Depending on the availability and quality of data, a meta-analysis will be done. Alternatively, a qualitative synthesis of data is planned. The systematic review follows the PRISMA recommendations. Finally, risk of bias and quality of the evidence of included studies will be assessed. DISCUSSION To our knowledge, this will be the first systematic review to examine the effect of early interventions that promote parental sensitivity of parents of preterm infants in the neonatal intensive care unit. The results of this review will guide development of best practice guidelines and recommendations for further research and will have implications for neonatal clinical practice.

Effects of an intervention program on maternal and paternal parenting stress after preterm birth: A randomized trial. Early Hum Dev 2016; 103:17-25.

Abstract
BACKGROUND Preterm birth causes parenting stress and increases the risk of developmental disorders in children. Our objective was to assess the impact of an early psychological intervention, Triadic parent-infant Relationship Therapy (TRT), on parenting stress, parental mental health and preterm infant development in the motor, language, social, behavioral and emotional domains at a corrected age of 18months. METHODS Sixty-five families of preterm infants were randomly assigned to the intervention group (n=33) or the control group (n=32). Families of full-term children (n=24) were also recruited. Intervention focused on the triadic relationship and aimed to improve parenting stress by supporting parental mental health to promote infant development. The main outcome was assessed with the Parenting Stress Index Short Form (PSI-SF). RESULTS Highly significant differences at 18months were observed for the mother and father in overall PSI-SF scores, with 16.6, and 11.7 points, respectively, in favor of the intervention group. Children in the intervention group demonstrated higher full-scale developmental quotients than the preterm controls (an 8.7-point difference) along with lower scores on behavioral tests (a 5.8-point difference at 18months). At 18months, results for children in the intervention group showed no significant differences compared to the full-term group or were even better. CONCLUSIONS Our study provides sound evidence for the efficiency of the TRT program to reduce parenting stress and improve parental mental health for both parents, thus fostering the infant's overall development.

Abstract
OBJECTIVE To investigate the difference in quality of life (QOL) between small for gestational age (SGA) and appropriate for gestational age (AGA) infants during early childhood, and to investigate the factors influcing the QOL. METHODS The Infant and Toddler Quality of Life Questionnaire-47 (ITQOL-SF47) was used to investigate the QOL of 1 to 3-year-old children born SGA and AGA who visited the child health care division. QOL was compared between SGA (n=203) and AGA groups (n=130), between the catch-up (n=119) and no-catch-up subgroups (n=84) of children born SGA, and between the single healthcare (n=144) and multiple healthcare subgroups (n=59) of children born SGA. The generalized linear model was used to investigate the factors influencing the QOL. RESULTS The total ITQOL score of the SGA group was significantly lower than that of the AGA group (630±99 vs 716±84; P<0.05). In children born SGA, the no-catch-up subgroup had a significantly lower total ITQOL score than the catch-up subgroup (602±96 vs 649±97; P<0.05), and the single healthcare subgroup had a significantly lower total ITQOL score than the multiple healthcare subgroup (616±94 vs 657±107; P<0.05). The generalized linear model analysis showed that in children born SGA who had catch-up or multiple healthcare visits, who were female or living in the Chongqing urban area, or their mothers had a higher educational levels had higher total ITQOL score. CONCLUSIONS SGA infants have lower QOL than AGA infats during their early childhood. Proper promotion of catch-up growth and regular healthcare visits will contribute to the improvement of the QOL of SGA infants. The QOL of SGA infants is also influcenced by children's sex, residence and the degree of mothers' educational levels.

Abstract
BACKGROUND Infants born preterm are at increased risk of developing cognitive and motor impairment compared with infants born at term. Early developmental interventions have been provided in the clinical setting with the aim of improving overall functional outcomes for these infants. Long-term benefits of these programmes remain unclear. OBJECTIVES Primary objective To compare the effectiveness of early developmental intervention programmes provided post hospital discharge to prevent motor or cognitive impairment in preterm (< 37 weeks) infants versus standard medical follow-up of preterm infants at infancy (zero to < three years), preschool age (three to < five years), school age (five to < 18 years) and adulthood (≥ 18 years). Secondary objectives To perform subgroup analyses to determine the following.• Effects of gestational age, birth weight and brain injury (periventricular leukomalacia (PVL)/intraventricular haemorrhage (IVH)) on cognitive and motor outcomes when early intervention is compared with standard follow-up. ∘ Gestational age: < 28 weeks, 28 to < 32 weeks, 32 to < 37 weeks. ∘ Birth weight: < 1000 grams, 1000 to < 1500 grams, 1500 to < 2500 grams. ∘ Brain injury: absence or presence of grade III or grade IV IVH or cystic PVL (or both) or an abnormal ultrasound/magnetic resonance image (MRI) before initiation of the intervention.• Effects of interventions started during inpatient stay with a post-discharge component versus standard follow-up care.• Effects of interventions focused on the parent-infant relationship, infant development or both compared with standard follow-up care.To perform sensitivity analysis to identify the following.• Effects on motor and cognitive impairment when early developmental interventions are provided within high-quality randomised trials with low risk of bias for sequence generation, allocation concealment, blinding of outcome measures and selective reporting bias. SEARCH METHODS The search strategy of the Cochrane Neonatal Review Group was used to identify randomised and quasi-randomised controlled trials of early developmental interventions provided post hospital discharge. Two review authors independently searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE Advanced, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and EMBASE (1966 to August 2015). SELECTION CRITERIA Studies included had to be randomised or quasi-randomised controlled trials of early developmental intervention programmes that began within the first 12 months of life for infants born before 37 weeks' gestational age. Interventions could commence on an inpatient basis but had to include a post-discharge component for inclusion in this review. Outcome measures were not prespecified, other than that they had to assess cognitive outcomes, motor outcomes or both. Rates of cerebral palsy were documented. DATA COLLECTION AND ANALYSIS Two independent review authors extracted and entered data. Cognitive and motor outcomes were pooled by four age groups: infancy (zero to < three years), preschool age (three to < five years), school age (five to < 18 years) and adulthood (≥ 18 years). Meta-analysis using RevMan 5.1 was carried out to determine the effects of early developmental interventions at each age range. Subgroup analyses focused on gestational age, birth weight, brain injury, commencement of the intervention, focus of the intervention and study quality. MAIN RESULTS Twenty-five studies met the inclusion criteria (3615 randomly assigned participants). Only 12 of these studies were randomised controlled trials with appropriate allocation concealment. Variability was evident with regard to focus and intensity of the intervention, participant characteristics and length of follow-up. Meta-analysis led to the conclusion that intervention improved cognitive outcomes at infancy (developmental quotient (DQ): standardised mean difference (SMD) 0.32 standard deviations (SDs), 95% confidence interval (CI) 0.16 to 0.47; P value < 0.001; 16 studies; 2372 participants) and at preschool age (intelligence quotient (IQ); SMD 0.43 SDs, 95% CI 0.32 to 0.54; P value < 0.001; eight studies; 1436 participants). However, this effect was not sustained at school age (IQ: SMD 0.18 SDs, 95% CI -0.08 to 0.43; P value = 0.17; five studies; 1372 participants). Heterogeneity between studies for cognitive outcomes at infancy and at school age was significant. With regards to motor outcomes, meta-analysis of 12 studies showed a significant effect in favour of early developmental interventions at infancy only; however, this effect was small (motor scale DQ: SMD 0.10 SDs, 95% CI 0.01 to 0.19; P value = 0.03; 12 studies; 1895 participants). No effect was noted on the rate of cerebral palsy among survivors (risk ratio (RR) 0.82, 95% CI 0.52 to 1.27; seven studies; 985 participants). Little evidence showed a positive effect on motor outcomes in the long term, but only five included studies reported outcomes at preschool age (n = 3) or at school age (n = 2). AUTHORS' CONCLUSIONS Early intervention programmes for preterm infants have a positive influence on cognitive and motor outcomes during infancy, with cognitive benefits persisting into preschool age. A great deal of heterogeneity between studies was due to the variety of early developmental intervention programmes tested and to gestational ages of included preterm infants; thus, comparisons of intervention programmes were limited. Further research is needed to determine which early developmental interventions are most effective in improving cognitive and motor outcomes, and to discern the longer-term effects of these programmes.

Abstract
Abstract
OBJECTIVE. We conducted a meta-analysis to examine the association between early intervention and mental or neuromusculoskeletal and movement-related functions of children born low birthweight (LBW) or preterm.
METHOD. The meta-analysis included 16 studies that yielded 97 effects. Q and I2 values were used to determine heterogeneity. Publication bias was evaluated using Egger’s regression intercept test and a funnel plot.
RESULTS. The association between early intervention and either mental or neuromusculoskeletal and movement-related functions yielded a significant but small effect size (d = .219, p < .0001). Heterogeneity was statistically insignificant.
CONCLUSION. Participation in early intervention programs addressing mental or neuromusculoskeletal and movement-related functions in children born LBW or preterm results in significant improvements in these areas.

Abstract
OBJECTIVE to evaluate neonatal sepsis as a risk factor for abnormal neuromotor and cognitive development in very low birth weight preterm infants at 12 months of corrected age. METHODS this was a prospective cohort study that followed the neuromotor and cognitive development of 194 very low birth weight preterm infants discharged from a public neonatal intensive care unit. The Bayley Scale of Infant Development (second edition) at 12 months of corrected age was used. The outcomes were the results of the clinical/neurological evaluation and the scores of the psychomotor development index (PDI) and mental development index (MDI) of the Bayley Scale of Infant Development II. The association between neonatal sepsis and neuromotor development and between neonatal sepsis and cognitive development was verified by logistic regression analysis. RESULTS mean birth weight was 1,119g (SD: 247) and mean gestational age was 29 weeks and 6 days (SD: 2). Approximately 44.3%(n=86) of the infants had neonatal sepsis and 40.7% (n=79) had abnormal neuromotor development and/or abnormal psychomotor development index (PDI < 85) at 12 months of corrected age. On the mental scale, 76 (39.1%) children presented abnormal cognitive development (MDI<85). Children with neonatal sepsis were 2.5 times more likely to develop changes in neuromotor development (OR: 2.50; CI: 1.23-5.10). There was no association between neonatal sepsis and cognitive development impairment. CONCLUSION neonatal sepsis was an independent risk factor for neuromotor development impairment at 12 months of corrected age, but not for mental development impairment.

Abstract
Empirical studies have documented a variety of social abnormalities in infancy that indicate risk for later social and behavioral difficulties. There is very little research illustrating the presence of such behavioral vulnerabilities with frequent repeated measures, and the feasibility of designing interventions for improving social engagement in infants under one year of age. In the context of a multiple baseline research design, three young infants, ages 4, 7, and 9 months referred for concerns about social engagement were assessed for affect, social interest, eye contact avoidance, and response to name. Additionally, the feasibility of implementing an intervention to target social behaviors was examined. Results demonstrated that: (1) consistently low or erratic levels of social behavior were evident throughout the baseline assessment period; (2) these patterns could be improved with a brief intervention (a modified Pivotal Response Treatment) showing an immediate increase and stability of social engagement; and (3) social engagement remained at a stable and high level at follow-up. The results are discussed in terms of implications of early assessment and intervention for clinical populations, including infants with Autism Spectrum Disorder.

Abstract
BACKGROUND Preterm infants are at greater risk for neurodevelopmental disabilities than full term infants. Interventions supporting parents to improve the quality of the infant's environment should improve developmental outcomes for preterm infants. Many interventions that involve parents do not measure parental change, nor is it clear which intervention components are associated with improved parental outcomes. The aim of this review was to categorize the key components of early intervention programs and determine the direct effects of components on parents, as well as their preterm infants. METHODS MEDLINE, EMBASE, CINAHL, ERIC, and Cochrane Database of Systematic Reviews were searched between 1990 and December 2011. Eligible randomized controlled trials (RCTs) included an early intervention for preterm infants, involved parents, and had a community component. Of 2465 titles and abstracts identified, 254 full text articles were screened, and 18 met inclusion criteria. Eleven of these studies reported maternal outcomes of stress, anxiety, depressive symptoms, self-efficacy, and sensitivity/responsiveness in interactions with the infant. Meta-analyses using a random effects model were conducted with these 11 studies. RESULTS Interventions employed multiple components categorized as (a) psychosocial support, (b) parent education, and/or (c) therapeutic developmental interventions targeting the infant. All interventions used some form of parenting education. The reporting quality of most trials was adequate, and the risk of bias was low based on the Cochrane Collaboration tool. Meta-analyses demonstrated limited effects of interventions on maternal stress (Z = 0.40, p = 0.69) and sensitivity/responsiveness (Z = 1.84, p = 0.07). There were positive pooled effects of interventions on maternal anxiety (Z = 2.54, p = 0.01), depressive symptoms (Z = 4.04, p <.0001), and self-efficacy (Z = 2.05, p = 0.04). CONCLUSIONS Positive and clinically meaningful effects of early interventions were seen in some psychosocial aspects of mothers of preterm infants. This review was limited by the heterogeneity of outcome measures and inadequate reporting of statistics. IMPLICATIONS OF KEY FINDINGS: Interventions for preterm infants and their mothers should consider including psychosocial support for mothers. If the intervention involves mothers, outcomes for both mothers and preterm infants should be measured to better understand the mechanisms for change.

Abstract
BACKGROUND Infants born preterm are at increased risk of developing cognitive and motor impairments compared with infants born at term. Early developmental interventions have been used in the clinical setting with the aim of improving the overall functional outcome for these infants. However, the long-term benefit of these programmes remains unclear. OBJECTIVES To review the effectiveness of early developmental intervention post-discharge from hospital for preterm (< 37 weeks) infants on motor or cognitive development. SEARCH METHODS The Cochrane Neonatal Review group search strategy was used to identify randomised and quasi-randomised controlled trials of early developmental interventions post hospital discharge. Two review authors independently searched the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE Advanced, CINAHL, PsycINFO and EMBASE (1966 through to October 2012). SELECTION CRITERIA Studies included had to be randomised or quasi-randomised controlled trials of early developmental intervention programmes that began within the first 12 months of life for infants born at < 37 weeks with no major congenital abnormalities. Intervention could commence as an inpatient; however, a post-discharge component was necessary to be included in this review. The outcome measures were not pre-specified other than that they had to assess cognitive ability, motor ability or both. The rates of cerebral palsy were also documented. DATA COLLECTION AND ANALYSIS Data were extracted and entered by two independent review authors. Cognitive and motor outcomes were pooled in four age groups - infancy (zero to < three years), pre-school age (three to < five years), school age (five to 17 years) and adulthood (≥ 18 years). Meta-analysis was carried out using RevMan 5.1 to determine the effects of early developmental intervention at each age range. Subgroup analysis was carried out in relation to gestational age, birthweight, brain injury, commencement of intervention and focus of intervention. MAIN RESULTS Twenty-one studies met the inclusion criteria (3133 randomised patients). Only 10 of these studies were RCTs with appropriate allocation concealment. There was variability with regard to the focus and intensity of the intervention, subject characteristics and in length of follow-up. Meta-analysis concluded that intervention improved cognitive outcomes at infant age (developmental quotient (DQ): standardised mean difference (SMD) 0.31 standard deviations (SD); 95% confidence interval (CI) 0.13 to 0.50; P < 0.001; 13 studies; 2147 patients), and pre-school age (intelligence quotient (IQ); SMD 0.45 SD; 95% CI 0.34 to 0.57; P < 0.001; six studies; 1276 patients). However, this effect was not sustained at school age (IQ: SMD 0.25 SD; 95% CI -0.10 to 0.61; P = 0.16; five studies; 1242 patients). There was significant heterogeneity between studies for cognitive outcomes at infant and school ages. In regards to motor outcomes, meta-analysis of 10 studies showed a significant effect in favour of early developmental interventions; however, the effect was small (motor scale developmental quotient (DQ): SMD 0.10 SD; 95% CI 0.00 to 0.19; P = 0.04; 10 studies; 1745 patients). There was no effect on the rate of cerebral palsy in survivors; risk ratio (RR) 0.89; 95% CI 0.55 to 1.44; five studies; 737 patients). There was little evidence for a positive effect on motor outcomes in the long term, with only five of the included studies reporting outcomes at pre-school or school age. AUTHORS' CONCLUSIONS Early intervention programmes for preterm infants have a positive influence on cognitive and motor outcomes during infancy, with the cognitive benefits persisting into pre-school age. There is a great deal of heterogeneity between studies due to the variety of early developmental intervention programmes trialled and gestational ages of the preterm infants included, which limits the comparisons of intervention programmes. Further research is needed to determine which early developmental interventions are the most effective at improving cognitive and motor outcomes, and on the longer-term effects of these programmes.

Abstract
BACKGROUND We have previously reported improved caregiver mental health and infant behavior at 2 years following a home-based preventive care program for very preterm infants and their caregivers. This study aimed to determine the longer-term effectiveness of the program by reviewing caregivers and children at preschool age. METHODS One hundred twenty very preterm infants (<30 weeks' gestation) were randomly allocated to intervention (n = 61) or control (n = 59) groups. The intervention included 9 home visits over the first year of life targeting infant development, parent mental health, and the parent-infant relationship. The control group received standard care. At 4 years' corrected age, child cognitive, behavioral, and motor functioning and caregiver mental health were assessed. RESULTS At age 4 years, 105 (89%) children were reviewed. There was little evidence of differences in cognitive or motor functioning between groups. The intervention group had lower scores for child internalizing behaviors than the control group (mean difference -5.3, 95% confidence interval [CI] -9.6 to -0.9, P = .02). Caregivers in the intervention group had fewer anxiety symptoms (mean difference -1.8, 95% CI -3.3 to -0.4, P = .01) and were less likely to exhibit "at-risk" anxiety (odds ratio 0.3, 95% CI 0.1 to 0.7, P = .01) than those in the control group. CONCLUSIONS This home-based preventive care program for very preterm infants has selective long-term benefits, including less caregiver anxiety and reduced preschooler internalizing behaviors.

Abstract
Premature birth has been associated with a number of adverse maternal psychological outcomes that include depression, anxiety, and trauma as well as adverse effects on maternal coping ability and parenting style. Infants and children who were premature are more likely to have poorer cognitive and developmental functioning and, thus, may be harder to parent. In response to these findings, there have been a number of educational and behavioral interventions developed that target maternal psychological functioning, parenting and aspects of the parent-infant relationship. Since the last comprehensive review of this topic in 2002, there have been a significant number of developments in the quality of the studies conducted and the theoretical models that address the experience of parents of premature infants. In the current review, eighteen new interventions were identified and grouped into four categories based on treatment length and the target of the intervention. Findings suggest a trend towards early, brief interventions that are theoretically based, specifically target parent trauma, and utilize cognitive behavioral techniques. Although it is difficult to generalize study findings, conclusions from the review suggest that targeted interventions may have positive effects on both maternal and infant outcomes.

Abstract
This article provides an integrative review of the effectiveness of and possible developmental mechanisms associated with preventive interventions for preterm children. An analysis of randomized clinical trials carried out within the last 15 years was framed within a contemporary developmental model emphasizing the role of parental adjustments to preterm children's characteristics. Evidence suggested positive outcomes could be understood in terms of improvements in developmental pathways associated with parental sensitive-responsiveness and child participation in intensive intervention-oriented child care. Implications for the critical role of the Medical Home model for preventive interventions for preterm children were discussed.

Abstract
OBJECTIVE This study tested the efficacy of a brief intervention (Cues program) with mothers of very low birth weight (VLBW <1500 g) infants. The primary hypothesis was that mothers in the Cues program would report lower levels of anxiety compared with mothers in the control group. Secondary hypotheses examined whether Cues mothers would report less stress, depression, and role restriction, and exhibit more sensitive interactive behavior, than control group mothers. METHODS A total of 121 mothers of VLBW infants were randomly assigned to either the experimental (Cues) intervention or an attention control (Care) condition. The Cues program combined training to reduce anxiety and enhance sensitivity. The control group received general information about infant care. Both programs were initiated during the neonatal intensive care unit stay. Maternal anxiety, stress, depression, and demographic variables were evaluated at baseline, prior to randomization. Postintervention outcomes were assessed during a home visit when the infant was ∼6 to 8 weeks of corrected age. RESULTS Although mothers in the Cues group demonstrated greater knowledge of the content of the experimental intervention than mothers in the Care group, the groups did not differ in levels of anxiety, depression, and symptoms of posttraumatic stress. They were similar in their reports of parental role restrictions and stress related to the infant's appearance and behavior. Cues and Care group mothers were equally sensitive in interaction with their infants. CONCLUSION Nonspecific attention was as effective as an early skill-based intervention in reducing maternal anxiety and enhancing sensitive behavior in mothers of VLBW infants.

Abstract
There is a scarcity of empirically validated treatments for infants and toddlers under age 3 years with autism spectrum disorders (ASD), as well as a scarcity of empirical investigation into successful intervention characteristics for this population. Yet early screening efforts are focused on identifying autism risk in children under age 3 years. In order to build ASD interventions for infants and toddlers upon a foundation of evidence-based characteristics, the current paper presents the results of a systematic literature search and effect size analysis of efficacious interventions for infants and toddlers with other developmental disorders: those who were born prematurely, have developmental impairments, or are at high risk for developmental impairments due to the presence of a biological or familial condition associated with developmental impairments. A review of 32 controlled, high-quality experimental studies revealed that the most efficacious interventions routinely used a combination of four specific intervention procedures, including (1) parent involvement in intervention, including ongoing parent coaching that focused both on parental responsivity and sensitivity to child cues and on teaching families to provide the infant interventions, (2) individualization to each infant's developmental profile, (3) focusing on a broad rather than a narrow range of learning targets, and (4) temporal characteristics involving beginning as early as the risk is detected and providing greater intensity and duration of the intervention. These four characteristics of efficacious interventions for infants and toddlers with other developmental challenges likely represent a solid foundation from which researchers and clinicians can build efficacious interventions for infants and toddlers at risk for or affected by ASD.

Abstract
OBJECTIVE: The study aimed to assess bronchopulmonary dysplasia (BPD) as a predisposing factor for alteration in the psychomotor development index (PDI) in premature infants and verify the incidence of neuromotor alterations at 6 months corrected age. METHOD: This was a prospective cohort study that followed the neuromotor development of 152 very low birth weight premature infants, with psychomotor development index as the outcome. The study used the Bayley Scale of Infant Development at 6 months corrected age, and neurological examination. RESULTS: Incidence of BPD was 13.2% (n=20). Logistic regression analysis showed an association between BPD and altered psychomotor development index (OR 3.98; 95%CI: 1.04-15.1) after adjusting for confounding variables. Neurological examination was altered in 67.1% of the 152 infants. CONCLUSION: Bronchopulmonary dysplasia acted as an independent predisposing factor for alteration in the psychomotor development index in premature infants at 6 months corrected age.

Abstract
The performance of very low birth weight preterm infants, in terms of cognition and expressive language, was analyzed and compared with that of term infants with the Protocol for Expressive Language and Cognition Development Observation (PELCDO). The study involved 12 very low birth weight preterm infants and 20 term infants, all of whom were evaluated monthly. Sessions were videotaped, and data were analyzed according to this specific protocol. Our results suggest that cognition and expressive language develop significantly later in very low birth weight preterm infants than in the term. We found positive correlations for cognitive and expressive language development, the delay becoming more evident after 6 months of age, persisting through the sensorimotor period, and continuing into the beginning of preoperational period, indicating the importance of follow-up evaluation, defining the true needs of such infants and identifying the ideal moment for speech-language intervention.

Abstract
OBJECTIVE To explore whether health promotion efforts targeted at preschool-age children can improve health across the life span and improve future economic returns to society. METHODS We selected 4 health topics to review-tobacco exposure, unintentional injury, obesity, and mental health-because they are clinically and epidemiologically significant, and represent the complex nature of health problems in this early period of life. The peer-reviewed literature was searched to assess the level of evidence for short- and long-term health impacts of health promotion and disease prevention interventions for children from before birth to age 5. This review sought to document the monetary burden of poor child health, the cost implications of preventing and treating child health problems, and the net benefit of the interventions. RESULTS The evidence is compelling that these 4 topics-tobacco exposure, unintentional injury, obesity, and mental health-constitute a significant burden on the health of children and are the early antecedents of significant health problems across the life span. The evidence for the cost consequences of these problems is strong, although more uneven than the epidemiological data. The available evidence for the effectiveness of interventions in this age group was strongest in the case of preventing tobacco exposure and injuries, was limited to smaller-scale clinical interventions in the case of mental health, and was least available for efforts to prevent obesity among preschoolers. CONCLUSIONS Currently available research justifies the implementation of health interventions in the prenatal to preschool period-especially to reduce tobacco exposure and prevent injuries. There is an urgent need for carefully targeted, rigorous research to examine the longitudinal causal relationships and provide stronger economic data to help policy makers make the case that the entire society will benefit from wise investment in improving the health of preschool-age children and their families.

Abstract
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.

Abstract
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.

Abstract
Very-low-birth-weight infants are at much higher risk for cognitive and language delays but the nature of such deficits is not clearly understood. Given increasing rates of prematurity and infants born very-low-birth-weight, examination of mechanisms that underlie poorer developmental outcome is essential. We investigated language and cognitive abilities in very-low and normal birth-weight infants to determine whether performance differences were due to poorer global cognitive performance or to deficits in specific processing abilities. Thirty-two very-low and 32 normal birth-weight infants received visual and auditory-visual habituation recognition-memory tasks, and standardized language and cognitive assessments. Very-low-birth-weight infants performed more poorly on visual and auditory-visual habituation tasks and scored lower than controls on cognitive and language measures. These findings suggest that differences in language abilities in very-low-birth-weight children may be part of a global deficit that impacts many areas of cognitive functioning rather than a specific impairment in rapid auditory processing.
