Sleep habits and sleep disturbance in elementary school-aged children.

Abstract: Relatively little is known about sleep habits, sleep disturbances, and the consequences of disordered sleep in school-aged children. This descriptive study examined a variety of common sleep behaviors in a group of 494 elementary school children, grades kindergarten through fourth, using a battery of sleep questionnaires that included parent, teacher, and self-report surveys. The prevalence of parent-defined sleep problems ranged from 3.7% (Sleep-Disordered Breathing) to 15.1% (Bedtime Resistance), with 37% of the overall sample described as having significant sleep problems in at least one sleep domain. Younger children were more likely than older children to have sleep problems noted by parents (particularly bedtime struggles and night wakings), as well as by teacher and self-report. Children tended to identify more sleep problems by self-report, particularly sleep-onset delay and night wakings, than did their parents. Overall, approximately 10% of the sample was identified by all three measures as having significant problems with daytime sleepiness. The results of this study emphasize the importance of screening for sleep disorders in this age group in the clinical setting. The need for consensus regarding the use of sleep screening instruments and the definition of "problem" sleep in school-aged children is also discussed.

Impact of recurrent and chronic pain on child and family daily functioning: a critical review of the literature.

Abstract: The author reviewed the current status of research on the impact of recurrent and chronic pain on everyday functioning of children and families and organized the research findings around the specific life contexts (e.g., school, peers) that may be affected by pain. Although findings demonstrate that many different aspects of child and family life are affected by pain, the prevalence and severity of children's functional limitations associated with pain remain unknown. Few treatment studies for pediatric recurrent and chronic pain have focused on enhancing children's functioning. It has been shown, however, that functional outcomes can be improved by cognitive-behavioral interventions. Recommendations for research on functional outcomes and implications for clinical practice are discussed.

Reciprocal social behavior in children with and without pervasive developmental disorders.

Abstract: An invariant feature of pervasive developmental disorders (PDDs) is a relative deficit in the capacity for reciprocal social behavior (RSB). The authors acquired teacher reports of RSB in 287 schoolchildren and parent reports of RSB in 158 child psychiatric patients using a new research instrument, the Social Reciprocity Scale. Total scores on this measure of RSB were continuously distributed in all groups of subjects; children with PDDs scored significantly higher for the degree of deficits in RSB than did clinical or nonclinical controls. Latent class analysis and factor analysis failed to demonstrate separate categories of deficiency for core autistic symptomatology and more general impairments in RSB, consistent with the notion of a "broader autism phenotype." Assessments of RSB on a continuous scale may be useful clinically for characterizing the behavior of children whose social deficits fall below the threshold for a full diagnosis of autism. They may also be useful in genetic-linkage studies of autistic spectrum disorders.

Behavioral adjustment in children with asthma: a meta-analysis.

Abstract: This study is a meta-analytic review of the behavioral adjustment of children and adolescents with asthma. Of 78 studies initially reviewed, 26 studies (encompassing 28 data sets), reflecting data on nearly 5,000 children with asthma (mean age = 8.4 years; 40% female), met criteria for inclusion. Effect size estimates were calculated across studies using standard methods. Separate effect sizes were calculated for internalizing and externalizing behavioral problems, degrees of asthma severity, and differences in control group used (i.e., sample controls or normative data). Results indicate that children with asthma have more behavioral difficulties than do healthy children, with the effect for internalizing behaviors being greater than that for externalizing behaviors (d(mn) = .73 vs .40). Increased asthma severity was associated with greater behavioral difficulties. Results did not differ by comparison group (healthy controls vs normative data). The findings suggest that patients with asthma, particularly children with severe asthma, should be considered at higher risk for behavioral difficulties that may necessitate psychosocial intervention.

Behavior problems and group-based parent education programs.

Abstract: Behavior problems in children are an important social, educational, and health issue. The prevalence of these problems, their stability over time, their poor prognosis, and their costs to both individuals and the society, all point to the need for primary prevention and early effective interventions. A systematic review examined the effectiveness of group parent education programs that aimed to improve behavior problems in 3- to 10-year-old children. The phrase "parent education program" is used here to refer to group-based programs with a standardized format aimed at enhancing parenting skills. The term "behavior problems" is used to refer to children exhibiting externalizing problems such as temper tantrums, aggression, and noncompliance. It does not include children diagnosed as having attention-deficit hyperactivity disorder. This review focused explicitly on measures of child behavioral outcomes, which are only small, albeit important, outcomes of parent education programs. Reviews focusing on other clinically relevant outcomes are also needed, including parental well-being and attitudes towards parenting. Other reviews are also needed to collate evidence concerning the effectiveness of parent education programs with other age-groups, i.e., preschoolers and adolescents, and in improving other aspects of child well-being. The review included published studies only and as such may have been influenced by a "publication bias." Inclusion criteria comprised the use of a waiting list, a no-treatment or placebo control group, and at least one standardized measure assessing the child's behavior. Only studies published after 1970 that included at least one "group-based" parent education program were included. A total of 255 primary studies were identified, but only 16 of these and 2 follow-up studies met all of the specified inclusion criteria. Critical appraisal of these 16 studies revealed considerable heterogeneity in the interventions, the populations studied, and the outcome measures used. Nevertheless, these studies suggest that structured parent education programs can be effective in producing positive change in both parental perceptions and objective measures of children's behavior and that these changes are maintained over time. Because of the small number of controlled studies and their methodological variations, caution should be exercised before these findings are generalized broadly.

Disturbances of attachment in young children adopted from institutions.

Abstract: In this article, the author describes a discrepancy between popular media accounts of reactive attachment disorder (RAD) and its clinical and scientific description. The literature on serious disturbances of attachment in children adopted out of institutions is reviewed. The author concludes that children adopted from institutions are at dramatically increased risk for disturbances, although the majority of such children do not demonstrate problems. Both the duration of deprivation and the postinstitutional caregiving environment seem to be importantly related to outcome. Inhibited/withdrawn RAD is exceedingly uncommon in children adopted from institutions (at least after 1 or more years), but disinhibited/indiscriminate RAD is quite persistent. Long after children become attached to adoptive parents, a number of them continue to exhibit indiscriminate sociability. Three explanations for this divergence of recovery curves are considered. It is likely that future systematic studies will illuminate many areas that are unclear at this time. J Dev Behav Pediatr 21:230-236, 2000.

Effects of prenatal tobacco exposure on preschoolers' behavior.

Abstract: This is a longitudinal study of the relationship between prenatal tobacco exposure and the development of behavior problems in 672 children at the age of 3 years. Women from a prenatal clinic were interviewed about substance use at the end of each trimester of their pregnancy and at 3 years postpartum. Children were assessed at the age of 3 years with maternal ratings of behavior problems, activity, and attention. The prevalence of tobacco use was high in this cohort; 54.3% and 52.3% of the women smoked tobacco in the first and third trimesters of pregnancy, respectively. At 3 years postpartum, 61.6% of the women were smokers. There were significant effects of prenatal tobacco exposure on the children's behavior at age 3 years. Increases in scores on the Oppositional Behavior, Immaturity, Emotional Instability, Physical Aggression, and Activity scales and in the total score on the Toddler Behavior Checklist (TBC) were significantly associated with prenatal tobacco exposure. Smoking one pack of tobacco cigarettes per day during the third trimester of pregnancy was associated with an increase of 6 points in the total problem behavior score. Among the subscales of the TBC, tobacco exposure had the largest effect on oppositional behavior. Impulsivity and peer problems were associated with both prenatal and current tobacco exposure. Only current tobacco exposure predicted attention problems. Prenatal tobacco exposure had a significant negative effect on the development of behavior problems among preschoolers.

Family reinforcement of illness behavior: a comparison of adolescents with chronic fatigue syndrome, juvenile arthritis, and healthy controls.

Abstract: .Parental encouragement of illness behavior is hypothesized to correlate with psychosocial dysfunction in adolescents with chronic illness. To explore this hypothesis, adolescents aged 11 to 17 years with chronic fatigue syndrome (CFS) (n = 10), juvenile rheumatoid arthritis (JRA) (n = 16),

Thirty-six-month outcome of prenatal cocaine exposure for term or near-term infants: impact of early case management.

Abstract: Gestational cocaine use is associated with serious pregnancy complications having fetal and neonatal implications. However, many cocaine-abusing women deliver uneventfully at term. The purpose of this study was to assess the neurodevelopmental outcome for term or near-term infants after prenatal cocaine exposure and to determine whether that outcome would be modified by early, intensive family case management. Cocaine-exposed infants identified after delivery at an urban hospital were alternately assigned to receive case management (n = 70) or routine follow-up (n = 48). A matched, non-drug-exposed group of infants was identified for comparison (n = 41). Infants aged up to 36 months were serially evaluated in a multidisciplinary clinic with cognitive, psychomotor, and language testing. Group comparisons were performed using one-way analysis of variance. There were no statistical differences in mean cognitive, psychomotor, or language quotients between cocaine-exposed and non-drug-exposed infant groups aged up to 36 months. At 6 months of age, case-managed cocaine-exposed infants had a significantly higher mean Bayley Mental Developmental Index score than those who were routinely managed. However, no differences were present at subsequent assessments. Among cocaine-exposed infants who remained with their mothers at 36 months, verbal scores were significantly higher for case-managed compared with routine-managed infants. The negative effects of urban, low socioeconomic status may overshadow the impact of prenatal cocaine exposure on early childhood outcome for those infants born without prenatal complications.

Family experiences and factors associated with the diagnosis of fragile X syndrome.

Abstract: The authors interviewed 41 mothers of young boys with fragile X syndrome to determine the process by which they learned their child had fragile X syndrome. The average family had concerns about the child's development at 9 months of age. Developmental delay was determined at an average age of 24 months, and fragile X syndrome was diagnosed at a mean age of 35 months. Considerable variability was found in age of first concern, determination of delay, and diagnosis of fragile X syndrome. Three child variables (severity of delay, autistic behavior, temperament style) and four family variables (mother's age, mother's education, sibling status, social support) did not account for this variability, although birth year did (children born more recently were somewhat more likely to be identified earlier). Families often encountered physicians who initially discounted concerns or said that it was too early to determine whether a problem did indeed exist. Given current knowledge and practice, improving the early identification (under 3 years of age) of children with fragile X syndrome is likely to remain difficult if based solely on behavioral and clinical observations.

Medication management of stimulants in pediatric practice settings: a national perspective.

Abstract: Using a nationally representative sample of office-based physicians, the management practices of pediatricians, psychiatrists, and family practice physicians were investigated. The major aims were to determine (1) what types of services these physicians were providing to children who received stimulants, (2) what factors predicted receipt of stimulants, and (3) whether these practices were concordant or discordant with professional consensus on diagnosis and treatment of attention-deficit hyperactivity disorders (ADHD). Prescribing and management practice data from the 1995 National Ambulatory Medical Care Survey (NAMCS) were analyzed for children ages 0 to 17 years who were seen for psychiatric problems and received stimulant medication. Results indicated that 2 million visits by children were made in 1995 to psychiatrists, pediatricians, or family practitioners in which psychotropic medications were prescribed. In pediatric visits where stimulant medication was prescribed, mental health counseling was provided 47.3% of the time and psychotherapy 21.6%. Follow-up arrangements were made in 79.1% of the visits. Psychiatrists were significantly more likely to provide psychotherapy and to specify follow-up visits than were pediatricians, but less likely to provide other health counseling. Controlling for demographic and physician effects, the factors with the most significant effect on the probability of receiving stimulants were geographic region (living in the South), race (being white), receiving mental health counseling, not receiving psychotherapy, and having health insurance. Less than 50% of pediatric visits for psychiatric reasons involving stimulant medications included any form of psychosocial intervention. In 21% of these visits, no recommendations were made for follow-up care. These practices diverge from National Institutes of Health (NIH) consensus panel recommendations and association-issued practice parameters.

Neurobehavioral functioning of healthy preterm infants of varying gestational ages.

Abstract: Little information is available regarding the behavioral repertoire of healthy, yet prematurely born, infants. To address this problem, the Assessment of Preterm Infants' Behavior (APIB) was used 10 to 14 days after birth in a cross-sectional comparison of 42 healthy newborn infants: 16 full-term infants (gestational age at birth [GA] = 40 weeks), 13 close to full-term infants (GA = 37 weeks), and 13 preterm infants (GA = 34 weeks). Groups differed on four background variables that were used as covariates in subsequent analyses. Significant group differences were found on 12 of 29 outcome variables, including measures of autonomic, motor, state, attention/interaction, and self-regulatory systems, as well as a measure of overall behavioral organization. Pairwise comparison showed that preterm and full-term infants differed on all 12 variables whereas preterm and close to full-term infants differed on 11 of the 12 variables. Furthermore, full-term and close to full-term infants differed on 4 of the 12 variables, including measures of the autonomic, motor, and state systems. Full-term and close to full-term infants were behaviorally more similar to one another than either group was to the preterm infants, yet there were important differences even between full-term and close to full-term infants.

The Role of Sensory Stimulation in Perinatal Development: Insights from Comparative Research for Care of the High-Risk Infant

Abstract: Studies of avian and mammalian species have highlighted the importance of normal patterns of perinatal sensory experience to early perceptual and behavioral capabilities, including recognition and preference for maternal olfactory, auditory, and visual information, the capability for prenatal and postnatal auditory learning, and sensitivity to temporal and spatial features of sensory stimulation. This animal-based research suggests that the effects that alterations of perinatal sensory stimulation may have on early perceptual and behavioral development likely depend on a number of related factors, including (a) the timing of the stimulation relative to the developmental stage of the organism, (b) the amount of stimulation provided or denied the young organism, and (c) the type of sensory stimulation presented. This article reviews research drawn from comparative developmental psychology and psychobiology on perinatal perceptual development and explores how it can inform research and practice concerned with the developmentally appropriate care of the high-risk infant.

Cortisol and social stressors in children with fragile X: a pilot study.

Abstract: Evidence of neuroendocrine dysfunction, behavioral features of social anxiety and avoidance, and neuroanatomical abnormalities suggest that abnormal hypothalamic-pituitary-adrenal (HPA) function may be a component of the fragile X (fra X) syndrome. In this preliminary study, salivary cortisol levels of males (n = 8, mean age = 13.5 yr) and females (n = 7, mean age = 13.9 yr) with the fra X full mutation were studied for 3 days. Day 1 was an experimental day, during which subjects experienced a Social Stressor task midmorning. Days 2 and 3 were routine days, during which the subjects were engaged in their typical activities. Saliva samples were collected before breakfast, lunch, dinner, and bedtime. On the experimental day, the prelunch sample collection occurred 30 and 90 minutes after the Social Stressor task. Compared with children's norms, the combined group of males and females with fra X had significantly higher cortisol levels in the prelunch and the prebedtime samples for the routine days. Comparisons between the two fra X groups for the experimental day revealed similar diurnal patterns for cortisol level. However, compared with females with fra X, males with fra X had significantly higher cortisol levels at two points during the day: 30 minutes after the social stressor and at bedtime. These preliminary data suggest that individuals with fra X have abnormal HPA function. Understanding the relations among HPA dysfunction, abnormalities in brain structure and/or function, and maladaptive behavior and cognition in fra X could inform the design of early interventions using pharmacological or environmental measures designed to normalize neuroendocrine function.

War trauma experience and behavioral screening of Bosnian refugee children resettled in Massachusetts.

Abstract: The authors assessed war violence exposure and behavioral symptoms in Bosnian refugee children in Massachusetts and the utility of behavioral screening of refugees during the Refugee Health Assessment (RHA), required of newly arrived refugees. The study was a survey of 31 Bosnian refugee children in 1996 at the International Clinic of Boston Medical Center, the state's largest contracted provider of the RHA. Subjects were also offered referrals to appropriate mental health services. Sixty-eight percent experienced long-term separation from a parent. Eighty-one percent were directly exposed to armed combat. Seventy-one percent experienced the death of a close friend or relative. Fifty-two percent experienced economic deprivation. Families reported behavioral symptoms for 77% of children. Only one family expressed interest in psychosocial services of any kind. Large numbers of Bosnian refugees are likely to have experienced traumatic war violence and are at risk of behavioral symptoms. The RHA affords opportunities to screen for behavioral problems but not to intervene. Primary care providers and other clinicians should be aware of likely recurrences of symptoms in high-risk children such as these.

Predictors of parental distress after congenital disabilities.

Abstract: This study investigated the relationship between child functional independence, family dynamics, psychosocial factors, and level of distress in parents of children with congenital disabilities. The Vineland Adaptive Behavior Scales, the Family Assessment Device (FAD), and the Brief Symptom Inventory (BSI) were administered to 60 parents of children with cerebral palsy, 34 parents of children with spina bifida, and 27 parents of children with limb deficiencies. Stepwise multiple regression analyses indicated that the Roles scale from the FAD and the presence of a significant new psychosocial stressor within the previous 6 months were statistically significant predictors of the level of parental distress as assessed by the BSI. Exploration of the extent to which families have adaptive distributions of responsibilities for dealing with domestic tasks, as well as with unrelated life stressors, may be helpful in identifying those parents of children with congenital disabilities who are at risk for distress.

Comparison of eating attitudes and behaviors among adolescent and young women with type 1 diabetes mellitus and phenylketonuria.

Abstract: The purpose of this study was to assess the eating attitudes and behaviors associated with two chronic diseases that have strong dietary treatment components: type 1 diabetes mellitus and phenylketonuria (PKU). Participants consisted of female campers and staff members who were attending one of two summer camps that specialize in the care of females with type 1 diabetes mellitus (N = 54) and PKU (N = 30). Eating attitudes and behaviors, psychological adjustment, and disease-specific knowledge were assessed using standardized and nonstandardized self-report questionnaires. There was no overall difference in the presence of disordered eating symptomatology between those with diabetes and those with PKU. However, differences in patterns of eating attitudes and behaviors were observed. The data suggest that living with chronic diseases which are treated with dietary management may adversely affect eating attitudes and behaviors and may increase susceptibility to the development of eating disturbances.

The behavior profile of children and adolescents with short stature.

Abstract: The relation between behavior profiles and short stature was assessed in 311 children and adolescents with various diagnoses. The mean Child Behavior Checklist (CBCL) and Youth Self-Report (YSR) profile of the entire group of children with growth deficiency significantly exceeded population norms on all scales and scores. However, there were no significant differences between five major diagnostic groups across CBCL scales. Neither age, gender, socioeconomic status, nor severity of short stature had any effect on the various CBCL and YSR scores. Correlations between parent (CBCL) and child (YSR) scores were significant, though only at a low to medium level. It was concluded that probably short stature per se, rather than a specific diagnosis, has an impact on behavioral adaptation.

Measuring difficult temperament the easy way.

Abstract: In this study, the authors introduce a new measure of infant temperament, the Pictorial Assessment of Temperament (PAT), and provide information about its psychometric qualities based on findings from a study of 132 mothers and infants. The PAT is a 10-item measure of "difficult" temperament that is quick and easy to use and avoids some of the inherent problems in existing paper-and-pencil measures of temperament (e.g., complexity of response choices, dependence on respondents' educational level and verbal skills). It has convergent validity with the Revised Infant Temperament Questionnaire and with observed behavior in a laboratory procedure, moderate reliability and stability over time, and moderate agreement between mothers' and fathers' reports. Predictive validity was demonstrated by significant associations with the children's later disruptive behavior, behavior problems, lack of sociability, and negativity in interactions with their mother. Parent characteristics (agreeableness, extraversion, neuroticism, sensitivity, depression) were not related to scores on the PAT, demonstrating its discriminant validity.

Neuroimaging: applications in disorders of early brain development.

Abstract: Neuroimaging techniques have established new connections between etiological factors and disorders of early brain development. Neuroimaging has also strengthened the link between patterns of selective vulnerability in the developing brain and clinical syndromes, especially cerebral palsy. Both computed tomography (CT) and magnetic resonance imaging (MRI) identify early developmental malformations, including neural tube defects, callosal dysgenesis, neuronal migration disorders, posterior fossa malformations, and hydrocephalus. Periventricular white matter damage, most commonly seen in premature infants, is best visualized by cranial ultrasonography in the neonatal period and on MRI later in childhood. In term infants and children with genetic metabolic diseases, various applications of nuclear magnetic resonance, including MRI, have important diagnostic roles. The utility of diffusion-weighted imaging, MR spectroscopy, and functional MRI to further understanding of brain injury, biochemistry, and function is under active investigation. In summary, selecting the appropriate neuroimaging technique can improve diagnosis and management of childhood neurodevelopmental disorders.

Neuropsychological functioning in patients with asymptomatic congenital cytomegalovirus infection.

Abstract: Congenital cytomegalovirus (CMV) infection has an affinity for the central nervous system and has been implicated in a variety of neurological impairments. Analysis of cognitive functioning in children with asymptomatic congenital CMV infection, however, has revealed no general intellectual deficits. The present study was designed to explore neuropsychological test performance in these children, compared with healthy control subjects, providing data from more sensitive measures of neurocognitive functioning. The sample consisted of 109 children diagnosed with asymptomatic congenital CMV infection and 173 control subjects who were compared on tests measuring various aspects of perceptual and motor functioning, memory, problem solving, and traditional intelligence measures. Young (41NDASH6 yr) control patients performed significantly better on the Full-Scale but not the Verbal or Performance intelligence quotient (IQ) measures than patients with asymptomatic congenital CMV infection, without accompanying consistent neuropsychological performance differences. However, no IQ or neuropsychological differences were found between groups of older children. The present study adds to the existing literature finding no reliable, lasting differences in IQ scores and adds to our knowledge by finding no reliable, lasting differences in neuropsychological test performance.

Maternal child-rearing behaviors and correlates in rural minority areas of Yunnan, China.

Abstract: An epidemiological survey of maternal child-rearing behaviors was conducted in the rural minority areas of Yunnan, China. An interview of 2019 rural mothers of Hani, Yi, Hui, Miao, and Han and 544 urban mothers with children younger than 7 years of age showed that 51.7% of these rural mothers placed their infants in swaddling clothes. In the rural sample, exclusive breastfeeding occurred at frequency rates of 76.7% and 34.2% during 3 and 6 months postpartum, respectively. Maternal training and playing behaviors were reported less frequently, whereas physical punishment for children's misbehavior was more commonly found in the child-rearing behavior of rural mothers. Maternal child-rearing behaviors differed significantly among ethnic groups as well as between urban and rural areas. Maternal child-rearing behaviors were significantly associated with maternal education level, family type, family income, maternal age at delivery, and number of children in the family. Children's gender had no significant association with maternal child-rearing behaviors.

Hypothyroxinemia of prematurity and infant neurodevelopment: a pilot study.

Abstract: To assess whether hypothyroxinemia has specific effects on neurodevelopment in premature infants, thyroid hormone levels were determined at 2 weeks of life and 40 weeks postconceptional age (PCA), and infants were evaluated at 3 months corrected age using the Bayley Scales of Infant Development and Early Infancy Temperament Questionnaire. Additional attention scales were derived from the factor analysis of relevant Bayley items. Fifteen infants born between 30 and 35 weeks and 21 full-term infants were studied. Results indicated no group differences on the Bayley or derived attention scales, whereas the temperament questionnaire revealed lower sensory thresholds and greater reactivity in the preterm group. The preterm group had normal thyroxine (T4) levels at 2 weeks of age, which declined by 40 weeks PCA for both free T4 (p < .01 for reference value and p < .0001 for gestational age-adjusted value) and total T4 (p < .05 for age-adjusted value). Correlations revealed that higher 40-week PCA free T4 levels were associated with better attentiveness ratings (p < .01 for reference and p < .0001 for gestational-age values) and sustained attention (p < .05) and higher 40-week total T4 with better motor skills (p < .05 for gestational-age value). These findings signify that a mild degree of hypothyroxinemia is evident in preterm infants without neurological risk and predicts subsequently poorer cognitive and motor abilities.
