Influence of reporting effects on the association between maternal depression and child autism spectrum disorder behaviors

Reproducibility between preschool and school-age Social Responsiveness Scale forms in the Environmental influences on Child Health Outcomes program

Evidence suggests core autism trait consistency in older children, but development of these traits is variable in early childhood. The Social Responsiveness Scale (SRS) measures autism-related traits and broader autism phenotype, with two age-dependent forms in childhood (preschool, 2.5-4.5 years; school age, 4-18 years). Score consistency has been observed within forms, though reliability across forms has not been evaluated. Using data from the Environmental Influences on Child Health Outcomes (ECHO) program (n = 853), preschool, and school-age SRS scores were collected via maternal report when children were an average of 3.0 and 5.8 years, respectively. We compared reproducibility of SRS total scores (T-scores) and agreement above a clinically meaningful cutoff (T-scores ≥ 60) and examined predictors of discordance in cutoff scores across forms. Participant scores across forms were similar (mean difference: 3.3 points; standard deviation: 7), though preschool scores were on average lower than school-age scores. Most children (88%) were classified below the cutoff on both forms, and overall concordance was high (92%). However, discordance was higher in cohorts following younger siblings of autistic children (16%). Proportions of children with an autism diagnoses were also higher among those with discordant scores (27%) than among those with concordant scores (4%). Our findings indicate SRS scores are broadly reproducible across preschool and school-age forms, particularly for capturing broader, nonclinical traits, but also suggest that greater variability of autism-related traits in preschool-age children may reduce reliability with later school-age scores for those in the clinical range.

High Depressive Symptoms, Low Family Functioning, and Low Self-Efficacy in Mothers of Children With Autism Spectrum Disorder Compared to Two Control Groups

BACKGROUND

Parents of children with autism spectrum disorder (ASD) face unique challenges in raising their children, and they are at higher risk for depression compared to parents of children with typical development (TD) and other disabilities.

AIMS

(1) To compare prevalence of depressive symptoms among mothers of children with ASD (n = 101), Down syndrome (DS, n = 101), and TD (n = 43) and (2) to describe the relationships among depression, self-efficacy, and family functioning, and describe the mediating role of maternal child care self-efficacy between depressive symptoms and child behavior.

METHODS

In this cross-sectional study, mothers completed the Social Communication Questionnaire, Aberrant Behavior Checklist, Patient Health Questionnaire-9 (PHQ-9), Family Assessment Device General Functioning Scale, and Maternal Self-Efficacy Scale.

RESULTS

Mothers of children with ASD had significantly higher mean PHQ-9 scores (p < .001), higher proportion of positive depression screening (p < .001), and lower family functioning (p < .001). Better family functioning is associated with less depression, better self-efficacy, and less severe ASD symptoms and behaviors. Self-efficacy mediated the relationship between depression and child ASD symptoms, and problematic behavior.

CONCLUSIONS

The rates of reported history of depression and low family functioning in mothers of children with ASD are twice the rate in mothers of children with DS and TD. Maternal child care self-efficacy is protective against maternal depression, even in the presence of severe child problematic behaviors and ASD symptoms. Interventions that increase child care self-efficacy and family functioning may be helpful in addressing depression in mothers of children with ASD.

Measuring the association between behavioural services and outcomes in young children with autism spectrum disorder

BACKGROUND

Children with autism spectrum disorder (ASD) receive a wide range of services.

AIMS

To examine the association between behavioural services received by children with ASD between ages 2 and 5 years and outcomes during primary school years.

METHODS

A total of 414 preschool-aged children diagnosed with ASD were enrolled at five Canadian sites and were assessed within four months of diagnosis (T1), six months later (T2), 12 months later (T3), at school entry (T4), and then annually (T5-T8) to 11 years of age. The association between the receipt of behavioural services during T1 to T3 and T8 outcomes related to adaptive behaviour and behavioural problems was modelled using linear regressions adjusted for immigrant status, family income, child's age at diagnosis, site, sex assigned at birth, and baseline (T1) outcome.

RESULTS

Children who received behavioural services during at least one time period from T1 to T3 did not have significantly different outcomes at T8 than children who did not receive any behavioural services.

IMPLICATIONS

Pre-school use of behavioural services was not found to affect outcomes during later childhood. Numerous challenges accompany studies of the association between pre-school service use and later outcomes in a heterogeneous ASD sample. Recommendations for study design are provided.

The Contagion of Psychopathology across Different Psychiatric Disorders: A Comparative Theoretical Analysis

Psychopathology is often studied and treated from an individual-centered approach. However, studies have shown that psychological distress is often best understood from a contextual, environmental perspective. This paper explores the literature on emotional contagion and symptom transmission in psychopathology, i.e., the complex ways in which one person's psychological distress may yield symptoms among others in his/her close environment. We argue that emotions, cognitions, and behaviors often do not stay within the borders of the individual, but rather represent intricate dynamic experiences that are shared by individuals, as well as transmitted between them. While this claim was comprehensively studied in the context of some disorders (e.g., secondary traumatization and the "mimicking" of symptoms among those close to a trauma survivor), it was very scarcely examined in the context of others. We aim to bridge this gap in knowledge by examining the literature on symptom transmission across four distinct psychiatric disorders: PTSD, major depression, OCD, and psychosis. We first review the literature on emotional contagion in each disorder separately, and then we subsequently conduct a comparative analysis highlighting the shared and differential mechanisms underlying these processes in all four disorders. In this era of transdiagnostic conceptualizations of psychopathology, such an examination is timely, and it may carry important clinical implications.

What Happens After a Positive Primary Care Autism Screen Among Historically Underserved Families? Predictors of Evaluation and Autism Diagnosis

OBJECTIVE

Families, pediatric providers, and service systems would benefit from expanded knowledge regarding (1) who is most likely to receive a recommended diagnostic evaluation after a positive primary care-administered autism screen and (2) of those who screen positive, who is most likely to be diagnosed with autism?

METHOD

Participants included 309 predominantly low-income, racial/ethnic minority parents and their child, aged 15 to 27 months, who screened positive on the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F). Generalized estimating equations were used to fit models of predictors for each binary outcome: receiving a diagnostic evaluation and receiving an autism diagnosis on evaluation.

RESULTS

Significant predictors of diagnostic evaluation receipt included the parent being older or non-Hispanic and the child having private insurance, lower child communication functioning, or receiving Early Intervention services. Significant predictors of an autism diagnosis on evaluation included male child, lower child communication functioning, screening directly in the parent's preferred language, White/non-Hispanic parent, and no parent history of mood disorder.

CONCLUSION

Children with younger parents, Hispanic ethnicity, relatively higher communication skills, public insurance, and no Early Intervention services were less likely to receive recommended diagnostic care. Reduced likelihood of autism diagnosis after a positive screen in non-White/non-Hispanic subgroups supports previous research indicating issues with M-CHAT-R/F positive predictive power for racial/ethnic minorities. The use of telephonic interpreters to administer screens, as opposed to directly screening in families' preferred languages, may lead to identification of fewer true autism cases. Thus, multilingual clinical staff capacity may improve positive predictive power of autism screening.

"Best Things": Parents Describe Their Children with Autism Spectrum Disorder Over Time

This study examined parental perceptions of the character traits of children with autism from early childhood to age 11. Parents (n = 153) provided descriptions of the "best things" about their children on the Child Behavior Checklist (CBCL) at ages 3-4, 7-8, and 10-11 years. Descriptions were coded using the framework of the Values in Action Classification of Strengths, with additional traits added as needed. Parent-endorsed traits included love, kindness, happiness, and humor in children across all ages and traits such as perseverance as children entered school. Higher CBCL scores were associated with a lower likelihood of endorsement for Humanity traits. Results are congruent with a contemporary neurodiversity perspective that emphasizes strengths and resilience.

Trajectories of emotional and behavioral problems from childhood to early adult life

LAY ABSTRACT

Although mental health problems are common in autism, relatively little is known about their stability and the factors that influence their persistence or change over the life-course. To address this, we use data from the Special Needs and Autism Project (SNAP) cohort studied at three time-points from 12 to 23 years. Using the parent-reported Strengths and Difficulties Questionnaire (SDQ) domains of conduct, emotional, and ADHD symptoms, we evaluated the role of child, family, and contextual characteristics on these three trajectories. Symptoms decreased significantly over time for all three domains, but many participants still scored above the published disorder cutoffs. Individuals showed high levels of persistence. Higher initial adaptive function and language levels predicted a greater decline in conduct and ADHD symptoms. In contrast, higher language functioning was associated with higher levels of emotional symptoms, as was lower levels of autism symptom severity and higher parental education. Those with higher neighborhood deprivation had higher initial conduct problems but a steeper decline over time. Our findings highlight that it may be possible to accurately predict mental health trajectories over this time period, which could help parents and carers in planning and help professionals target resources more efficiently.

Association Between Meconium Acetaminophen and Childhood Neurocognitive Development in GESTE, a Canadian Cohort Study

Acetaminophen is the only over-the-counter pain reliever that is not contraindicated during pregnancy, but recent studies have questioned whether acetaminophen is safe for the fetus, particularly the developing brain. This prospective birth cohort study probed the previously observed association between in utero exposure to acetaminophen and neurodevelopment by using concentrations of acetaminophen measured in meconium, which more objectively captures exposure of the fetus than maternal report. Exposure, measured by liquid chromatography coupled with tandem mass spectrometry, was categorized into nondetection, low detection, and high detection levels. At age 6-8 years, children completed a set of subtests from the Wechsler Intelligence Scale for Children, 4th edition. Additionally, this study examined potential effect modification by child sex on the association between acetaminophen exposure and neurodevelopment. In fully adjusted models, in utero exposure to acetaminophen was not statistically significantly associated with decreased scores on any of the examined subtests in all children combined (n = 118). The effect of in utero acetaminophen exposure on the Coding subtest was marginally significantly different among boys and girls, with girls performing significantly better on the task with higher levels of acetaminophen compared with girls with undetectable levels of exposure (βgirls, low = 2.83 [0.97, 4.70], βgirls, high = 1.95 [-0.03, 3.93], βboys, low = .02 [-1.78, 1.81], βboys, high = -.39 [-2.09, 1.31], pinteraction = .06). Effect modification by child sex was not observed on other subtests. These results do not support prior reports of adverse neurodevelopmental effects of in utero exposure to acetaminophen.

Profiles of Social and Coping Resources in Families of Children with Autism Spectrum Disorder: Relations to Parent and Child Outcomes

This study described empirically derived profiles of parents' personal and social coping resources in a sample of 207 families of children diagnosed with autism spectrum disorder. Latent Profile Analysis identified four family profiles based on socieoeconomic risk, coping strategy utilization, family functioning, available social supports, and perceptions of family-centered support. During the time of children's transition to school, parents in the most disadvantaged group experienced the highest levels of parenting stress and depression, and their children had significantly lower adaptive behaviour scores and more parent-reported behavior problems than children in the other three groups. Results highlight the need for systematic surveillance of family risk factors so that supports can be provided to enhance both parental well-being and children's developmental health.

Psychopathology in parents of children with autism spectrum disorder: A systematic review and meta-analysis of prevalence

Parents of children with autism spectrum disorder appear to experience high levels of psychological distress, yet little is known about the prevalence of psychological disorders in this population. The aim of this systematic review and meta-analysis was to estimate the proportion of these parents who experience clinically significant psychopathology. Articles reporting proportions of psychological disorders in a sample of parents of children with autism spectrum disorder were located. The initial search returned 25,988 articles. Thirty-one studies with a total sample of 9208 parents were included in the final review. The median meta-analytic proportions were 31% (95% confidence interval = [24%, 38%]) for depressive disorders, 33% (95% confidence interval = [20%, 48%]) for anxiety disorders, 10% (95% confidence interval = [1%, 41%]) for obsessive-compulsive disorder, 4% (95% confidence interval = [0%, 22%]) for personality disorders, 2% (95% confidence interval = [1%, 4%]) for alcohol and substance use disorders and 1% (95% confidence interval = [0%, 5%]) for schizophrenia spectrum disorders. Significant heterogeneity was detected in these categories. Further research is needed to gain more insight into variables that may moderate parental psychopathology. This review and meta-analysis is the first to provide prevalence estimates of psychological disorders in parents of children with autism spectrum disorder.

Maternal Impression Management in the Assessment of Childhood Depressive Symptomatology

BACKGROUND

Self-report instruments are commonly used to assess for childhood depressive symptoms. Historically, clinicians have relied heavily on parent-reports due to concerns about childrens' cognitive abilities to understand diagnostic questions. However, parents may also be unreliable reporters due to a lack of understanding of their child's symptomatology, overshadowing by their own problems, and tendencies to promote themselves more favourably in order to achieve desired assessment goals. One such variable that can lead to unreliable reporting is impression management, which is a goal-directed response in which an individual (e.g. mother or father) attempts to represent themselves, or their child, in a socially desirable way to the observer.

AIMS

This study examined the relationship between mothers who engage in impression management, as measured by the Parenting Stress Index-Short Form defensive responding subscale, and parent-/child-self-reports of depressive symptomatology in 106 mother-child dyads.

METHODS

106 clinic-referred children (mean child age = 10.06 years, range 7-16 years) were administered the Child Depression Inventory, and mothers (mean mother age = 40.80 years, range 27-57 years) were administered the Child-Behavior Checklist, Parenting Stress Index-Short Form, and Symptom Checklist-90-Revised.

RESULTS

As predicted, mothers who engaged in impression management under-reported their child's symptomatology on the anxious/depressed and withdrawn subscales of the Child Behavior Checklist. Moreover, the relationship between maternal-reported child depressive symptoms and child-reported depressive symptoms was moderated by impression management.

CONCLUSIONS

These results suggest that children may be more reliable reporters of their own depressive symptomatology when mothers are highly defensive or stressed.

Child, Maternal and Demographic Factors Influencing Caregiver-Reported Autistic Trait Symptomatology in Toddlers

Current research on children's autistic traits in the general population relies predominantly on caregiver-report, yet the extent to which individual, caregiver or demographic characteristics are associated with informants' ratings has not been sufficiently explored. In this study, caregivers of 396 Singaporean two-year-olds from a birth cohort study completed the Quantitative Checklist for Autism in Toddlers. Children's gender, cognitive functioning and birth order, maternal age, and ethnic group membership were not significant predictors of caregiver-reported autistic traits. Poorer child language development and higher maternal depressive symptoms significantly predicted more social-communicative autistic traits, while lower maternal education predicted more behavioural autistic traits. Children's language and informants' educational level and depressive symptomatology may need to be considered in caregiver-reports of autistic traits.

Criterion Validity of the Child's Challenging Behavior Scale, Version 2 (CCBS-2)

OBJECTIVE

The Child's Challenging Behavior Scale, Version 2 (CCBS-2), measures maternal rating of a child's challenging behaviors that compromise maternal mental health. The CCBS-2, the Child Behavior Checklist (CBCL), and the Strengths and Difficulties Questionnaire (SDQ) were compared in a sample of typically developing young Australian children.

METHOD

Criterion validity was investigated by correlating the CCBS-2 with "gold standard" measures (CBCL and SDQ subscales). Data were collected in a cross-sectional survey of mothers (N = 336) of children ages 3-9 yr.

RESULTS

Correlations with the CBCL externalizing subscales demonstrated moderate (ρ = .46) to strong (ρ = .66) correlations. Correlations with the SDQ externalizing behaviors subscales were moderate (ρ = .35) to strong (ρ = .60).

CONCLUSION

The criterion validity established in this study strengthens the psychometric properties that support ongoing development of the CCBS-2 as an efficient tool that may identify children in need of further evaluation.

Validation of eye-tracking measures of social attention as a potential biomarker for autism clinical trials

Social communication impairments are a core feature of autism spectrum disorder (ASD), and this class of symptoms is a target for treatments for the disorder. Measures of social attention, assessed via eye-gaze tracking (EGT), have been proposed as an early efficacy biomarker for clinical trials targeting social communication skills. EGT measures have been shown to differentiate children with ASD from typical children; however, there is less known about their relationships with social communication outcome measures that are typically used in ASD clinical trials. In the present study, an EGT task involving viewing a videotape of an actor making bids for a child's attention was evaluated in 25 children with ASD aged 24-72 months. Children's attention to the actor during the dyadic bid condition measured via EGT was found to be strongly associated with five well-validated caregiver-reported outcome measures that are commonly used to assess social communication in clinical trials. These results highlight the convergent validity of EGT measures of social attention in relation to caregiver-reported clinical measures. EGT holds promise as a non-invasive, quantitative, and objective biomarker that is associated with social communication abilities in children with ASD.

LAY SUMMARY

Eye-gaze tracking (EGT), an automated tool that tracks eye-gaze patterns, might help measure outcomes in clinical trials investigating interventions to treat autism spectrum disorders. In this study, an EGT task was evaluated in children with ASD, who watched a video with an actor talking directly to them. Patterns of eye-gaze were associated with caregiver-reported measures of social communication that are used in clinical trials. We show EGT may be a promising objective tool measuring outcomes.

Specificity, contexts, and reference groups matter when assessing autistic traits

Many of the personality and behavioral traits (e.g., social imperviousness, directness in conversation, lack of imagination, affinity for solitude, difficulty displaying emotions) that are known to be sensitive to context (with whom?) and reference group (according to whom?) also appear in questionnaire-based assessments of autistic traits. Therefore, two experiments investigated the effects of specifying contexts and reference groups when assessing autistic traits in autistic and non-autistic participants. Experiment 1 (124 autistic and 124 non-autistic participants) demonstrated that context matters when assessing autistic traits (F(1,244) = 267.5, p < .001, η²_p = .523). When the context of the Broad Autism Phenotype Questionnaire was specified as the participants’ out-group (e.g., “I like being around non-autistic people” or “I like being around autistic people”), both autistic and non-autistic participants self-reported having more autistic traits; when the context was specified as the participants’ in-group, participants reported having fewer autistic traits. Experiment 2 (82 autistic and 82 non-autistic participants) demonstrated that reference group matters when assessing autistic traits (F(2,160) = 94.38, p < .001, η²_p = .541). When the reference group on the Social Responsiveness Scale was specified as the participants’ out-group (e.g., “According to non-autistic people, I have unusual eye contact”), autistic participants reported having more autistic traits; when the reference group was their in-group, autistic participants reported having fewer autistic traits. Non-autistic participants appeared insensitive to reference group on the Social Responsiveness Scale. Exploratory analyses suggested that when neither the context nor the reference group is specified (for assessing autistic traits on the Autism-Spectrum Quotient), both autistic and non-autistic participants use the majority (“non-autistic people”) as the implied context and reference group.

Diary Reports of Concerns in Mothers of Infant Siblings of Children with Autism Across the First Year of Life

We examined the home-based concerns reported by mothers of infant siblings of children with autism across the first year of life. At all three ages measured, mothers of high-risk infants were significantly more likely than mothers of low-risk infants to report language, social communication, and restricted and repetitive behavior concerns but were not more likely to report general, medically based concerns. At 6 and 9 months of age, maternal concerns were poorly related to infant or family variables. At 12 months of age, there were moderate correlations between maternal concerns and infant behavior, and concerns were associated with the proband's autism symptoms and mothers' concurrent depressive symptoms. These findings highlight the need to examine high-risk infants' development in the family context.

Systematic review of tools to measure outcomes for young children with autism spectrum disorder

BACKGROUND

The needs of children with autism spectrum disorder (ASD) are complex and this is reflected in the number and diversity of outcomes assessed and measurement tools used to collect evidence about children's progress. Relevant outcomes include improvement in core ASD impairments, such as communication, social awareness, sensory sensitivities and repetitiveness; skills such as social functioning and play; participation outcomes such as social inclusion; and parent and family impact.

OBJECTIVES

To examine the measurement properties of tools used to measure progress and outcomes in children with ASD up to the age of 6 years. To identify outcome areas regarded as important by people with ASD and parents.

METHODS

The MeASURe (Measurement in Autism Spectrum disorder Under Review) research collaboration included ASD experts and review methodologists. We undertook systematic review of tools used in ASD early intervention and observational studies from 1992 to 2013; systematic review, using the COSMIN checklist (Consensus-based Standards for the selection of health Measurement Instruments) of papers addressing the measurement properties of identified tools in children with ASD; and synthesis of evidence and gaps. The review design and process was informed throughout by consultation with stakeholders including parents, young people with ASD, clinicians and researchers.

RESULTS

The conceptual framework developed for the review was drawn from the International Classification of Functioning, Disability and Health, including the domains 'Impairments', 'Activity Level Indicators', 'Participation', and 'Family Measures'. In review 1, 10,154 papers were sifted - 3091 by full text - and data extracted from 184; in total, 131 tools were identified, excluding observational coding, study-specific measures and those not in English. In review 2, 2665 papers were sifted and data concerning measurement properties of 57 (43%) tools were extracted from 128 papers. Evidence for the measurement properties of the reviewed tools was combined with information about their accessibility and presentation. Twelve tools were identified as having the strongest supporting evidence, the majority measuring autism characteristics and problem behaviour. The patchy evidence and limited scope of outcomes measured mean these tools do not constitute a 'recommended battery' for use. In particular, there is little evidence that the identified tools would be good at detecting change in intervention studies. The obvious gaps in available outcome measurement include well-being and participation outcomes for children, and family quality-of-life outcomes, domains particularly valued by our informants (young people with ASD and parents).

CONCLUSIONS

This is the first systematic review of the quality and appropriateness of tools designed to monitor progress and outcomes of young children with ASD. Although it was not possible to recommend fully robust tools at this stage, the review consolidates what is known about the field and will act as a benchmark for future developments. With input from parents and other stakeholders, recommendations are made about priority targets for research.

FUTURE WORK

Priorities include development of a tool to measure child quality of life in ASD, and validation of a potential primary outcome tool for trials of early social communication intervention.

Do children with gender dysphoria have intense/obsessional interests?

This study examined whether children clinically referred for gender dysphoria (GD) show increased symptoms of autism spectrum disorder (ASD). Circumscribed preoccupations or intense interests were considered as overlapping symptoms expressed in GD and ASD. In gender-referred children (n = 534; 82.2% male) and their siblings (n = 419; 57.5% male), we examined Items 9 and 66 on the Child Behavior Checklist, which measure obsessions and compulsions, respectively. Non-GD clinic-referred (n = 1,201; 48.5% male) and nonreferred (n = 1,201; 48.5% male) children were also examined. Gender-referred children were elevated compared to all other groups for Item 9, and compared to siblings and nonreferred children for Item 66. A gender-related theme was significantly more common for gender-referred boys than male siblings on Item 9 only. A gender-related theme was not significantly more common for gender-referred girls compared to their female siblings on either item. The findings for Item 9 support the idea that children with GD show an elevation in obsessional interests. For gender-referred boys in particular, gender-related themes constituted more than half of the examples provided by their mothers. Intense/obsessional interests in children with GD may be one of the factors underlying the purported link between GD and ASD.

Genomics of schizophrenia: time to consider the gut microbiome?

Research into the genomics of schizophrenia promises much, but so far is resplendent with failures to replicate, and has yielded little of therapeutic potential. Within our bodies resides a dynamic population of gut microbes forming a symbiotic superorganism comprising a myriad of bacteria of approximately 10(14) cells, containing 100 times the number of genes of the human genome and weighing approximately the same as the human brain. Recent preclinical investigations indicate that these microbes majorly impact on cognitive function and fundamental behavior patterns, such as social interaction and stress management. We are pivotally dependent on the neuroactive substances produced by such bacteria. The biological diversity of this ecosystem is established in the initial months of life and is highly impacted upon by environmental factors. To date, this vast quantity of DNA has been largely ignored in schizophrenia research. Perhaps it is time to reconsider this omission.

High incidence of sleep problems in children with developmental disorders: results of a questionnaire survey in a Japanese elementary school

OBJECTIVE

The aim of the present school-based questionnaire was to analyze the sleep problems of children with developmental disorders, such as pervasive developmental disorder and attention deficit hyperactivity disorder.

METHODS

The sleep problems of 43 children with developmental disorders were compared with those of 372 healthy children (control group). All children attended one public elementary school in Kurume, Japan; thus, the study avoided the potential bias associated with hospital-based surveys (i.e. a high prevalence of sleep disturbance) and provided a more complete picture of the children's academic performance and family situation compared with a control group under identical conditions. Children's sleep problems were measured with the Japanese version of the Children's Sleep Habits Questionnaire (CSHQ).

RESULTS

Children with developmental disorders had significantly higher total CSHQ scores, as well as mean scores on the parasomnias and sleep breathing subscales, than children in the control group. The total CSHQ score, bedtime resistance, sleep onset delay, and daytime sleepiness worsened with increasing age in children with developmental disorders; in contrast, these parameters were unchanged or became better with age in the control group. In children with developmental disorders, there was a significant association between a higher total CSHQ score and lower academic performance, but no such association was found in the control group. For both groups, children's sleep problems affected their parents' quality of sleep. There were no significant differences in physical, lifestyle, and sleep environmental factors, or in sleep/wake patterns, between the two groups.

CONCLUSIONS

Children with developmental disorders have poor sleep quality, which may affect academic performance. It is important for physicians to be aware of age-related differences in sleep problems in children with developmental disorders. Further studies are needed to identify the association between sleep quality and school behavioral performance.

Parenting stress in Chinese mothers of children with autism spectrum disorders

OBJECTIVE

Elevated parenting stress has been observed among mothers of children with autism spectrum disorders (ASDs) in western countries, but little is known about mothers of Han Chinese children. The aim of the current study was to further the knowledge about stress experienced by Chinese mothers of children with ASD by examining maternal parenting stress in Heilongjiang province of China.

METHODS

In this cross-sectional study, data about participants' demographic characteristics, parenting stress, anxiety, depression, child's behavioral problems, coping strategies, and social support were collected though a questionnaire survey. The participants included 150 families with ASD children, who were consecutively admitted to the clinics of the Children Development and Behavior Research Center in Harbin Medical University, Heilongjiang Disabled Persons Federation, and Mudanjiang Child Welfare Home.

RESULTS

The participants reported elevated parenting stress. Mothers' parenting stress was associated with levels of depression and anxiety, and child's behavioral symptoms. Child's behavioral symptoms, maternal anxiety, maternal depressive symptoms, and lack of governmental financial support were associated with overall parenting stress.

CONCLUSIONS

Government support may play an important role in reducing parenting stress in this population.
