Emotion regulation in children and adolescents.

Abstract: Within the past two decades, an "affect revolution" [Fischer and Tangney, Self-conscious Emotions: The Psychology of Shame, Guilt, Embarrassment, and Pride 1995:3-22] in research has revolutionized the ways in which emotion processes have been conceptualized and subsequently studied This review discusses the literature on emotion regulation (ER) in childhood and adolescence by first summarizing the trajectory of emotional development from infancy through adolescence, followed by a discussion of the biological and environmental influences on ER, and then a review of the literature linking ER to psychosocial functioning The penultimate section offers practical suggestions for identifying ER difficulties in children and strategies for intervention efforts Potential areas for future research conclude the review

Early language and communication development of infants later diagnosed with autism spectrum disorder.

Abstract: It is well recognized that delayed ''first words'' is among the most common presenting symptoms of autistic spectrum disorders (ASD). However, data on earlier language and communication development in children with ASD are limited to retrospective reports from parents and from home videos. In this study, we prospectively collected parent report data on early communication and language development in 97 infant siblings of children with ASD and 49 low-risk controls. Parents completed the MacArthur Communicative Development InventoryYInfant Form at 12 and 18 months. Analysis compared 3 groups defined on the basis of diagnostic assessment at 24 months: (1) siblings with ASD (n = 15), (2) siblings not meeting diagnostic criteria for ASD (n = 82), and (3) low-risk controls, none of whom had ASD (n = 49). Children with ASD showed delays in early language and communication compared with non-ASD siblings and controls. At 12 months, the ASD group was reported to understand significantly fewer phrases and to produce fewer gestures. At 18 months, they showed delays in their understanding of phrases, comprehension and production of single words, and use of gestures. Siblings not diagnosed with ASD also used fewer play-related gestures at 18 months than low-risk controls, even when children with identified language delays were excluded. Overall, this prospective study confirms that delays in communication and language development are apparent early in life in children with ASD, and emphasizes that developmental surveillance should include monitoring for delays in gesture, which may be among the earliest signs of ASD.

The developmental challenges associated with autism arise from a unique constellation of features spanning social communication and language, and behavioral adaptation. The predominant features of autism-related developmental disorders (referred to collectively as the autistic spectrum of disorders; ASD) include qualitative impairments in both verbal and nonverbal communication. 1 In addition, receptive and expres-

Early intensive behavioral treatment: replication of the UCLA model in a community setting.

Abstract: Although previous studies have shown favorable results with early intensive behavioral treatment (EIBT) for children with autism, it remains important to replicate these findings, particularly in community settings. The authors conducted a 3-year prospective outcome study that compared 2 groups: (1) 21 children who received 35 to 40 hours per week of EIBT from a community agency that replicated Lovaas' model of EIBT and (2) 21 age- and IQ-matched children in special education classes at local public schools. A quasi-experimental design was used, with assignment to groups based on parental preference. Assessments were conducted by independent examiners for IQ (Bayley Scales of Infant Development or Wechsler Preschool and Primary Scales of Intelligence), language (Reynell Developmental Language Scales), nonverbal skill (Merrill-Palmer Scale of Mental Tests), and adaptive behavior (Vineland Adaptive Behavior Scales). Analyses of covariance, with baseline scores as covariates and Year 1-3 assessments as repeated measures, revealed that, with treatment, the EIBT group obtained significantly higher IQ (F = 5.21, p = .03) and adaptive behavior scores (F = 7.84, p = .01) than did the comparison group. No difference between groups was found in either language comprehension (F = 3.82, p = .06) or nonverbal skill. Six of the 21 EIBT children were fully included into regular education without assistance at Year 3, and 11 others were included with support; in contrast, only 1 comparison child was placed primarily in regular education. Although the study was limited by the nonrandom assignment to groups, it does provide evidence that EIBT can be successfully implemented in a community setting. J Dev Behav Pediatr 27:145Y155, 2006.

Examination of the time between first evaluation and first autism spectrum diagnosis in a population-based sample.

Abstract: Early identification of young children with an autism spectrum disorder (ASD) can lead to earlier entry into intervention programs that support improved developmental outcomes. The purpose of the present study was to examine identification and diagnostic patterns of children with ASD who live in a large metropolitan area. One hundred fifteen 8-year-old children diagnosed with ASD were identified from a population-based surveillance system at the Centers for Disease Control and Prevention. Primary variables of interest included earliest age of evaluation and earliest age of diagnosis identified from surveillance records, type of initial ASD diagnosis, evaluation sources that documented first ASD diagnosis, characteristics of professionals assigning first ASD diagnosis, and diagnostic tools used to aid the diagnostic process. We found that children with ASD identified by the surveillance system were initially evaluated at a mean of 48 months but were not diagnosed with ASD until a mean age of 61 months. There were no differences in timing of diagnosis based on sex or racial/ethnic classification, although degree of impairment associated with ASD predicted mean age at first evaluation and mean age at first ASD diagnosis. Most children were identified at non-school sources, such as hospitals and clinics; 24% of the sample did not receive a documented ASD diagnosis until entering school. Most practitioners (70%) did not use a diagnostic instrument when assigning the first ASD diagnosis. Implications for early identification of ASD are discussed.

Autism spectrum disorders and attention-deficit/hyperactivity disorder in boys with the fragile X premutation.

Abstract: Fragile X syndrome (FXS) is caused by a full mutation expansion (>200 CGG repeats) in the FMR1 gene that results in a deficiency of the fragile X mental retardation protein. Although most individuals with the premutation (55-200 CGG repeats) are considered unaffected by FXS, recent case studies have documented children with the premutation who have cognitive deficits, behavioral problems, and/or autism spectrum disorders. The objective of this study was to compare the prevalence of autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD) symptoms in boys with the premutation who presented as probands, in brothers with the premutation who did not present as probands, and in normal brothers of premutation and/or full mutation carriers. Participants included 43 male children: 14 probands who presented to clinic, 13 nonprobands who were identified through cascade testing (routine genetic testing of family members after identification of a proband) and confirmed to have the premutation, and a control group of 16 male siblings of individuals with the fragile X premutation or full mutation who were negative for the FMR1 mutation. Participants came from 1 of 2 collaborative sites: University of California, Davis and La Trobe University in Australia. Parents completed the Conners' Global Index-Parent Version for assessing symptoms of ADHD and the Social Communication Questionnaire (SCQ) for identifying symptoms of ASD. Children who were in the ASD range on the SCQ (n = 13) underwent further evaluation with either the Autism Diagnostic Observation Schedule-Generic (n = 10) or the Autism Diagnostic Interview-Revised (n = 3). A final diagnosis of ASD included clinical assessment utilizing DSM-IV-TR criteria in addition to the standardized assessments. There was a higher rate of ASD in boys with the premutation presenting as probands (p < 0.001) or nonprobands (p < .04) compared with sibling controls without the premutation. In addition, probands had a significant increase in ADHD symptoms compared with controls (p < .0001). Of the probands, 93% had symptoms of ADHD and 79% had ASD. In the nonproband premutation group, 38% had symptoms of ADHD and 8% had ASD. Thirteen percent of sibling controls had symptoms of ADHD and none had ASD. IQ scores were similar in all 3 groups (p = .13), but the use of psychotropic medications was significantly higher in probands with the premutation compared with that in controls (p < .0001). Developmental problems have been observed in premutation carriers, particularly those who present clinically with behavioral difficulties. Although this study is based on a small sample size, it suggests that premutation carriers, even those who do not present clinically, may be at increased risk for an ASD and/or symptoms of ADHD. If the premutation is identified through cascade testing, then further assessment should be carried out for symptoms of ADHD, social deficits, or learning disabilities.

Frequency of gastrointestinal symptoms in children with autistic spectrum disorders and association with family history of autoimmune disease.

Abstract: This is a cross-sectional study that compares lifetime prevalence of gastrointestinal (GI) symptoms in children with autistic spectrum disorders (ASDs) and children with typical development and with other developmental disabilities (DDs) and examines the association of GI symptoms with a family history of autoimmune disease. A structured interview was performed in 50 children with ASD and 2 control groups matched for age, sex, and ethnicity-50 with typical development and 50 with other DDs. Seventy-four percent were boys with a mean age of 7.6 years (SD, +/-3.6). A history of GI symptoms was elicited in 70% of children with ASD compared with 28% of children with typical development (p <.001) and 42% of children with DD (p =.03). Abnormal stool pattern was more common in children with ASD (18%) than controls (typical development: 4%, p =.039; DD: 2%, p =.021). Food selectivity was also higher in children with ASD (60%) compared with those with typical development (22%, p =.001) and DD (36%, p =.023). Family history of autoimmune disease was reported in 38% of the ASD group and 34% of controls and was not associated with a differential rate of GI symptoms. In the multivariate analysis, autism (adjusted odds ratio (OR), 3.8; 95% confidence interval (CI), 1.7-11.2) and food selectivity (adjusted OR, 4.1; 95% CI, 1.8-9.1) were associated with GI symptoms. Children with ASD have a higher rate of GI symptoms than children with either typical development or other DDs. In this study, there was no association between a family history of autoimmune disease and GI symptoms in children with ASD.

Self-efficacy, outcome expectations, and diabetes self-management in adolescents with type 1 diabetes

Abstract: The goal of this research was to develop and evaluate measures of adolescent diabetes management self-efficacy and outcome expectations that reflect developmentally relevant, situation-specific challenges to current diabetes regimens. Self-efficacy for diabetes management, expected outcomes of adherence, adherence to the diabetes regimen, and glycemic control were assessed in 168 adolescents (ages 10-16 years) with type 1 diabetes. Factor analyses indicated a single scale for self-efficacy and two distinct factors representing positive and negative outcome expectations. Reliability and predictive validity of the new scales were supported. In regression analyses, self-efficacy and the interaction of self-efficacy with expectations of positive outcomes were significantly associated with diabetes self-management adherence and glycemic control in older adolescents. The effect of self-efficacy was greatest when adolescents had stronger beliefs in the beneficial outcomes of adherence. These brief measures can be used to identify youths at risk of poor diabetes self-management. Interventions targeting self-efficacy may lead to improved diabetes self-management.

Screening for autism spectrum disorders with the social communication questionnaire.

Abstract: The Social Communication Questionnaire (SCQ) is a parent report screening measure for autism spectrum disorders (ASDs) based on the Autism Diagnostic Interview-Revised (ADI-R). To examine its validity in a young sample, the SCQ was given to parents of 151 children at a mean age of 5 years, before assessment in tertiary autism or preschool clinics. Overall sensitivity was .71, the same for both clinics, but specificity was better for the preschool clinic (.62) than for the autism clinic (.53) reflecting fewer false-positives in the former. The "hit rate" was 65% with 28% of the children with autism missed by the SCQ at a cutoff score of 15 (false-negatives) and 38% of the nonautistic misidentified as having an ASD (false-positives). Item validity analysis, contrary to what was previously published, indicated that only 15 or 46% of the items distinguished between children with and without ASD in this much younger sample. False-negatives were somewhat higher functioning. The SCQ would seem to be a useful tool for identifying young children in need of further assessment and assisting in routing them to the appropriate clinic, especially if used in conjunction with a screening by a community professional. There remain questions about the "best" cutoff score to use and whether a shorter version, based on the items that distinguished autistic from nonautistic, would be more reliable and valid with younger children. Furthermore, it may be that an adjusted score is required when parents omit items or with nonverbal children who cannot be scored on some of the items.

Autism spectrum disorder screening and management practices among general pediatric providers.

Abstract: It is unclear to what extent general developmental/behavioral assessments are performed, if screening for autism spectrum disorders (ASDs) is being conducted, and what the barriers to providing such assessments are in routine pediatric practice. Therefore, this study examines (1) the factors influencing the use of general developmental and autism-specific screening tools in primary care pediatric practice, (2) the barriers to providing these assessments, and (3) pediatricians' beliefs regarding ASD prevalence. A cross-sectional survey was mailed in June 2004 to a 60% (n = 1119) random sample of Maryland and Delaware licensed pediatricians. In August 2004, a second mailing was sent to non-respondents. A total of 471 (42%) of the surveys were returned, and of those, 255 (54%) who practiced in general primary care were eligible. The sample was 47% male, 69% had more than 14 years' experience, 71% were in private practices, and 56% had fewer than 10 ASD patients. Most (82%) routinely screened for general developmental delays, but only 8% screened for ASD. The main reasons reported for not screening for ASD were lack of familiarity with tools (62%), referred to a specialist (47%), or not enough time (32%). Most specialist referrals (77%) were to a developmental pediatrician. Most pediatricians (71%) believed that ASD prevalence has increased, and nearly all attributed this to changes in diagnostic criteria and treatment. Service system limitations must be overcome to increase awareness and familiarity with screening tools, provide sufficient time and resources, improve screening, and enhance provider education.

Lessons from fragile X regarding neurobiology, autism, and neurodegeneration.

Abstract: The fragile X mental retardation 1 gene (FMR1) mutation causes two disorders: fragile X syndrome (FXS) in those with the full mutation and the fragile X-associated tremor/ataxia syndrome (FXTAS) in some older individuals with the premutation. FXS is caused by a deficiency of the FMR1 protein (FMRP) leading to dysregulation of many genes that create a phenotype with ADHD, anxiety, and autism. FXTAS is caused by the elevation of FMR1-mRNA to levels 2 to 8 times normal in the premutation. This causes an RNA gain of function toxicity leading to brain atrophy, white matter disease, neuronal and astrocytic inclusion formation, and subsequent ataxia, intention tremor, peripheral neuropathy, and cognitive decline. The neurobiology and pathophysiology of FXS and FXTAS are described in detail.

Parental perceptions and use of complementary and alternative medicine practices for children with autistic spectrum disorders in private practice.

Abstract: The prevalence of autistic spectrum disorder (ASD) in the United States is approximately 1 in 150 children. Many health care providers are unaware of parental beliefs and treatments, both medical and complementary, that parents use for their child with ASD. Understanding these beliefs and practices concerning diagnosis, cause, and utilization of medical and complementary care may help physicians provide better comprehensive care. Parents of children with ASD from 2 private practices-one in New York and one in New Jersey-were mailed a 6-page, self-administered survey. In addition to demographics and ASD type, the survey asked parents who diagnosed their child and if there was a perceived delay in that diagnosis; whether they believed there was any causal reason for their child's autism; what chronic symptoms, if any, their child experiences; and, if they had used any complementary and/or alternative therapies and at whose recommendation. Respondents included 77 of the 150 parents (51%) contacted. Most children were diagnosed by a neurologist and/or developmental pediatrician (54% and 47%, respectively). Average perceived delay in diagnosis was 18 months. Parents most frequently cited immunizations (54%), genetic predisposition (53%), and environmental exposure (38%) as a cause of their child's autism. Approximately half of children were reported as having at least one gastrointestinal, neurological, and/or allergic symptom; more than a third had immunological symptoms. Almost all parents (95%) indicated some use of complementary and alternative medicine (CAM) therapies, with most of the self-reported referrals generated from a physician or nurse (44%). Systemic complaints, parental beliefs, and use of CAM practices warrant open discussion by all health care professionals who provide care to this population.

Health-related quality of life in pediatric patients with irritable bowel syndrome: a comparative analysis.

Abstract: The primary aim of the study was to investigate the generic health-related quality of life (HRQOL) of pediatric patients meeting Rome II criteria for irritable bowel syndrome (IBS) in comparison to healthy children. The secondary aim was to compare pediatric patients with IBS to pediatric patients with Rome II criteria diagnosed functional abdominal pain (FAP) and patients with diagnosed organic gastrointestinal (GI) disorders. The study also investigated the associations between GI symptoms with generic HRQOL and evaluated group differences in school days missed and days sick in bed and needing care. HRQOL was measured with the PedsQLtrade mark 4.0 Generic Core Scales (Physical, Emotional, Social, and School Functioning). The PedsQLtrade mark was administered in outpatient pediatric gastroenterology clinics in California, Texas, and New Jersey. A total of 287 families (280 child self-report, 286 parent proxy-report) with children diagnosed with IBS (n = 123), FAP (n = 82), or organic GI disorders (n = 82) participated. Pediatric patients with IBS demonstrated significantly lower Physical, Emotional, Social, and School Functioning in comparison to healthy children, and comparable HRQOL to patients with FAP and organic GI diagnoses. GI symptoms were significantly associated with generic HRQOL. Patients with IBS demonstrated a significantly greater number of days missed from school, days sick in bed/too ill to play, and days needing someone to care for them than healthy children, but significantly fewer days than patients with FAP and organic GI disorders. Pediatric patients with IBS demonstrated impaired HRQOL in dimensions measuring Physical, Emotional, Social, and School Functioning. These findings suggest the need for targeted interventions to address these dimensions of impaired HRQOL.

Consequences and risks of <1000-g birth weight for neuropsychological skills, achievement, and adaptive functioning.

Abstract: A cohort of 219 children with extremely low birth weight (<1000 g, extremely low birth weight [ELBW]) born from 1992 to 1995 was followed to mean age 8 years to evaluate outcomes and identify risk factors. We compared 204 of these children with 176 term-born normal birth weight (NBW) controls on neuropsychological skills, academic achievement, and adaptive behavior. The ELBW group had worse outcomes than the NBW on all measures. Within the ELBW group, lower scores on NEPSY tests of executive function and memory were related to <750 g birth weight, B (SE) = -0.93 (0.36), p =.010; cranial ultrasound abnormality, B = -1.03 (0.22), p =.002; postnatal steroid therapy, B = -1.00 (0.33), p =.003; and necrotizing enterocolitis, B = -2.26 (0.75), p =.008. A lower score on the Test of Motor Proficiency was related to chronic lung disease, B = -7.33 (1.98), p <.001. Neuropsychological skills mediated the effects of neonatal risk on achievement and adaptive functioning. The findings document the neuropsychological consequences of ELBW at school age in a recently born cohort and identify risks for adverse outcomes.

Early screening for autism spectrum disorders: update on the modified checklist for autism in toddlers and other measures.

Abstract: Early intervention for autism spectrum disorders necessitates early detection. This need has led to widespread agreement across disciplines that screening is critical in very young children. Two screening issues are highlighted in this review. Level of screening refers to the type of sample: Level I is defined as an unselected sample, and Level II consists of selected children already identified as being at risk for a developmental disorder. Breadth or scope of screening refers to the range of difficulties the screening tool attempts to identify: broad screening instruments identify multiple range of developmental difficulties, whereas disorder-specific tools focus on a single disorder or class of disorders. Broad developmental instruments reviewed include the Parents' Evaluation of Developmental Status and the Ages and Stages Questionnaires; autism-specific tools reviewed include the Checklist for Autism in Toddlers, the Modified Checklist for Autism in Toddlers (M-CHAT), the Pervasive Developmental Disorders Screening Test, Second Edition, and the Screening Tool for Autism in Two-year-olds. The development of the M-CHAT, a Level I and Level II screening instrument, is described, and current research and clinical use of the M-CHAT are reviewed, including description of the structured follow-up interview which reduces the false-positive rate of the parent-report M-CHAT.

Autism and family home movies: a comprehensive review.

Abstract: In this article, we focus on the early development of autism studied through family home movies. We review all investigations published in English that met specific methodological standards, including the use of comparison samples, coding blind to group membership, and adequate levels of interrater reliability. After discussing in detail the pros and cons of the home-movie methodology, we review the results of all empirical studies conducted to date. We then present a summary of the features found consistently across studies that differentiate autism from typical development and mental retardation in the first 2 years of life. How family home movies can contribute to our understanding of the regression phenomenon is also addressed. Finally, the results are interpreted from both a theoretical and clinical point of view.

Parent and teacher rating scales in the evaluation of attention-deficit hyperactivity disorder: contribution to diagnosis and differential diagnosis in clinically referred children.

Abstract: .This study evaluated diagnostic utility of parent and teacher ratings in the attention-deficit hyperactivity disorder (ADHD) assessment and differential diagnosis of a clinical sample of children referred for suspected ADHD. Participants were 184 5- to 12-year-old children for whom the foll

Early medical history of children with autism spectrum disorders.

Abstract: Previous studies have suggested that children with autism spectrum disorders (ASD) may have different medical histories than nonspectrum children in several areas: their reactions to vaccinations, number of ear infections, chronic gastrointestinal problems, and use of antibiotics. Furthermore, some studies have found associations between regressive autism and gastrointestinal (GI) symptoms. The present study analyzes the medical records from birth to the age of 2 years of 99 children (24 typically developing; 75 with ASD, of whom 29 had parent-reported regression). Data were coded in the following areas: frequency and purpose of pediatrician visits, frequency and type of illnesses and medications, type and chronicity of GI complaints, date of vaccinations, growth data, and whether the pediatrician noted behaviors indicative of an ASD before the age of 2 years. Children with ASD were found to have significantly more ear infections than the typically developing children as well as to use significantly more antibiotics. Typically developing children had significantly more illness-related fevers. There was a nonsignificant trend toward the ASD group having more chronic gastrointestinal problems. There were no significant differences between the groups for the age of vaccination or for number of pediatrician visits. Finally, pediatricians noted symptoms of onset of possible autism, including language delay, for 44 of the 75 children with ASD and 2 of the 24 typical children. Results are discussed in terms of needs for future research.

Predictors of stress in parents of children with fetal alcohol spectrum disorders

Abstract: This study examined child characteristics and family factors as predictors of stress in the biological or adoptive parents of 6- to 12-year-old children with fetal alcohol spectrum disorders (FASDs). Impaired executive functioning, poorer adaptive functioning, externalizing and internalizing behavior problems, and adoptive parent status all made significant and independent contributions to the prediction of higher levels of child domain stress, as reported by parents on the Parenting Stress Index. Biological parent status and fewer family resources were associated with higher levels of parent domain stress. Teacher ratings of the child"s executive functioning impairments and externalizing and internalizing behavior problems also were associated with parent reports of child domain stress. Findings highlight the need to provide support not only to children with FASDs, but to their caregivers as well.

Elimination diets in autism spectrum disorders: any wheat amidst the chaff?

Abstract: The use of complementary or alternative treatment approaches in children with autism spectrum disorders (ASDs) is increasing, and the most popular of such approaches are diets that eliminate either gluten or casein, or both. The popularity of these diets indicates a need for more rigorous research into their efficacy. Owing to significant methodological flaws, the currently available data are inadequate to guide treatment recommendations. The purpose of this review is to examine the available trials of gluten/casein diets in children with ASDs regarding the strength of their findings and also concerning points that may be useful in the design of future studies. Seven trials of these diets in ASD are critically reviewed; 6 of these were uncontrolled trials and 1 used a single-blind design. All reported efficacy in reducing some autism symptoms, and 2 groups of investigators also reported improvement in nonverbal cognition. Design flaws in all of the studies weaken the confidence that can be placed in their findings. Careful double-blind, placebo-controlled studies are needed to evaluate whether actual benefit undergirds the diets' popularity and to provide better guidance to clinicians and caregivers. The literature currently available suggests that diets eliminating both gluten and casein (rather than either alone) should be studied first and that outcome measures should include assessments of nonverbal cognition.

Social Behavior Problems in Boys with Duchenne Muscular Dystrophy

Abstract: Duchenne muscular dystrophy (DMD) is a chronic, progressive pediatric disease that affects both muscle and brain. The objectives of the study were to examine parent reported behavior in children with DMD, investigate the influence of chronic illness, intellectual ability and etiology on behavior, and determine whether a specific behavioral profile is associated with DMD. Parental ratings of boys with DMD (n = 181) on the Child Behavior Checklist behavior scales were examined and compared to reported findings of children with other chronic illnesses, unaffected siblings of boys with DMD (n = 86), and children with cerebral palsy (CP) (n = 42). Increased ratings of general behavior problems were reported, and neither physical progression nor intellectual level contributed to behavioral ratings. Among the children with DMD, the Social Problem behavior scale had the greatest number of "clinically significant" ratings (34%). Between-group comparisons showed significantly more boys with DMD were rated as having social behavior problems than either the sibling or CP comparison groups. In addition to the increase in reported behavioral problems likely related to the effects of chronic illness, boys with DMD may be at heightened risk for specific social behavior problems. The specificity of the findings of the behavior profile in DMD may be partially due to the lack of dystrophin isoforms in the central nervous system, and not solely a reactive response to the illness.

Caring for migrant and refugee children: challenges associated with mental health care in pediatrics.

Abstract: This article reviews aspects of the mental health care of migrant and refugee children. It highlights the challenges of access to care for these children and of considering the role of pediatricians in their mental health care. It also looks at the sources of differences in presentation of mental health issues of migrant youth when compared with dominant culture youth, examining the contributions of culture, context, and the families' own views. Models of care will be described that have tried to elicit a better understanding of the difficulties migrant and refugee children may encounter. Some avenues through which we may expand our current psychiatric models of care will also be addressed. These avenues include the use of interpreters and cultural brokers, addressing the debate around ethnic matching between therapists and patients, promoting a sensitivity to otherness and mediation, and looking at the importance of time issues.

The influence of temperament on weight gain in early infancy

Abstract: Difficult temperament has been associated with fast weight gain and slow weight gain, although the latter mostly in referred subjects studies in late infancy. The current study set out to investigate early weight gain in relation to all domains of temperament in a community-screened sample. Weight gain from birth to 8 weeks was assessed in 75 infants recruited from local health care clinics who had demonstrated slow, average, or fast weight gain. Mothers completed a temperament questionnaire and a 2-day diary recording infant behaviors (sleeping, feeding, fussing, and crying). Weight gain from birth to 8 weeks was significantly related to infant temperament. The temperament dimension fear (acceptance or rejection of new objects or persons) was related to slow weight gain and the temperament dimension distress to limitations (negative emotionality and the infant's reaction to frustrating situations) was related to fast weight gain. The regression model explained 59% of the variance, with the temperament dimensions explaining 11%. Diary data showed that infants who scored high on fear tended to cry a lot, while infants with high scores on distress to limitations tended to sleep less and cry and fuss more. The results emphasize that different temperament domains influence slow and fast weight gain. In addition, the data suggest that infant temperament plays a part in physical development in early infancy.

Iron deficiency in infancy and mother-child interaction at 5 years.

Abstract: Five-year-old Costa Rican children, who had either chronic, severe iron deficiency or good iron status in infancy, were observed with their mothers during a structured interaction task in a laboratory setting and everyday interactions in their home. Child affect and behavior as well as the quality of mother-child interaction of the formerly chronic iron-deficient children (n = 40) were compared to those with good iron status in infancy (n = 102). Children who had chronic iron deficiency in infancy were more likely to display lower levels of physical activity, positive affect, and verbalization during the structured task at 5 years, despite iron therapy that corrected their iron deficiency anemia in infancy. Mother-child reciprocity during the structured task (e.g., eye contact, shared positive affect, turn taking) was more likely to be lower in the chronic iron deficiency group compared to the good iron group. Mothers of children in the chronic iron deficiency group showed less responsivity in both settings. These results show that children with chronic, severe iron deficiency in infancy continue at behavioral disadvantage relative to their peers at school entry. Sustained differences in mother-child interaction might contribute to the long-lasting behavioral and developmental alterations reported in children with chronic, severe iron deficiency in infancy.

Pretend play as a resource for children : Implications for pediatricians and health professionals

Abstract: Pretend play relates to many areas of adaptive functioning in child development including creativity, coping, and emotion regulation. Though pretend play interventions have been employed in medical settings for decades, there are few empirical studies of such interventions in the literature. A review of literature involving pretend play in medical settings indicates that pretend play interventions are effective in inpatient and outpatient settings for preventing and reducing anxiety and distress. Pretend play also has effects on pain, externalizing behavior, and adaptation to chronic illness. Such effects have been demonstrated in the short term; however they have not been shown to be stable in the long term, indicating that intermittent refresher sessions may be necessary. The sparse empirical literature regarding pretend play in medical settings spans a large number of journals and years, and conclusions are limited by methodological issues including measurement, treatment fidelity, research design, statistical procedures, and potential confounding variables. Despite these limitations, existing evidence suggests that play is a helpful intervention and that future research that addresses these limitations is warranted.

Characteristics of school-age children with autism.

Abstract: The objectives of this study were to provide a national profile of children with autism, to describe the impact of autism on school functioning, and to describe the utilization of services among children with autism. We performed a cross-sectional descriptive analysis of 9583 children (grades K-8) from the 2001 National Household Education Survey Before and After School Survey. We used parent-reported information to determine the prevalence of autism, and children with autism were compared to children without autism on sociodemographic measures and several measures of school functioning and utilization of services. The prevalence of autism in this sample was 66 per 10,000. Children with autism were proportionately represented in all communities and all regions of the country. While children with autism were equally likely to attend public schools compared to children without autism, they were significantly more likely to have learning difficulties and to carry multiple diagnoses, including attention deficit disorder and learning disability. Most of these children received services for their disability through the school district. In conclusion, data from this survey yielded a prevalence estimate of autism similar to other recent studies. Children with autism have performance and behavior problems that persist despite the availability of services to the majority of children. The important needs of these children warrant further attention.

Suffering in silence: why a developmental psychopathology perspective on selective mutism is needed.

Abstract: A developmental psychopathology perspective is offered in an effort to organize the existing literature regarding the etiology of selective mutism (SM), a relatively rare disorder in which a child consistently fails to speak in 1 or more social settings (e.g., school) despite speaking normally in other settings (e.g., home). Following a brief description of the history, prevalence, and course of the disorder, multiple pathways to the development of SM are discussed, with a focus on the various genetic, temperamental, psychological, and social/environmental systems that may be important in conceptualizing this unusual childhood disorder. The authors propose that SM develops due to a series of complex interactions among the various systems reviewed (e.g., a strong genetic loading for anxiety interacts with an existing communication disorder, resulting in heightened sensitivity to verbal interactions and mutism in some settings). Suggestions are provided for future longitudinal, twin/adoption, molecular genetic, and neuroimaging studies that would be particularly helpful in testing the pathways perspective on SM.
