Key components of early intervention programs for preterm infants and their parents: a systematic review and meta-analysis.

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.

Sensory processing and ADHD in children with fetal alcohol spectrum disorder.

BACKGROUND: Sensory processing problems are prevalent in children who have fetal alcohol spectrum disorder. It is unclear to what degree these problems are distinct from attention deficits as measured during the diagnostic process in these children. PURPOSE: To understand sensory processing in these children, which may assist with early identification and intervention. METHOD: The relationship between attention and sensory processing was studied in a retrospective sample of 26 Canadian children diagnosed with fetal alcohol spectrum disorder. FINDINGS: A very low correlation (r = .02) between Short Sensory Profile scores and the attention deficit hyperactivity index of the Conners' Parent Rating Scales was found for the five- to ten-year-old children. Sensory processing problems were found in 81% of the children, similar to other studies of children with fetal alcohol spectrum disorder. IMPLICATIONS: These findings can guide modifications of the environments, tasks, and approaches to children with fetal alcohol spectrum disorder.
