Predictors of Treatment Effectiveness for Youth with ASD and Comorbid Anxiety Disorders: It all Depends on the Family?

The study aimed to explore predictors of treatment effectiveness in a sample of 79 children with ASD who received cognitive behavioral therapy (CBT) for their anxiety disorders. Severity of anxiety disorders and anxiety symptoms were used to measure treatment effectiveness and was assessed pre-treatment, post-treatment, 3 months-, 1 and 2 years after CBT. Child characteristics and maternal anxiety did not predict treatment effect. Children with anxious fathers and children in ‘un-involved’ families had less anxiety symptoms at pre-treatment and displayed a less steep decline. Children from ‘authoritarian’ families showed higher pre-treatment anxiety levels but responded quite well to treatment. Findings stress the importance of parent (father) and family factors in the treatment of anxiety disorders in youth with ASD.     

Discriminant and Convergent Validity of the Anxiety Construct in Children with Autism Spectrum Disorders

Despite reports of high anxiety in children with autism spectrum disorders (ASD), there is controversy regarding differential diagnosis of ASD symptoms and anxiety symptoms. This study examined 88 children, aged 7–11 years, with ASD referred for concerns about anxiety. A multitrait-(social anxiety, separation anxiety, overall anxiety severity, and overall ASD severity), multimethod-(diagnostic interviews, parent-, and child-based measures) analysis was conducted. Results from structural equation modeling suggest statistical discrimination between anxiety and ASD severity and convergence among differing reports of two of the anxiety subdomains (separation anxiety and overall anxiety). These findings suggest that anxiety symptoms experienced by children with ASD are separate from ASD symptom severity and may instead reflect anxiety syndromes (e.g., separation anxiety) similar to those that occur in typically developing children.     

Traditional and Atypical Presentations of Anxiety in Youth with Autism Spectrum Disorder

We assessed anxiety consistent (i.e., “traditional”) and inconsistent (i.e., “atypical”) with diagnostic and statistical manual (DSM) definitions in autism spectrum disorder (ASD). Differential relationships between traditional anxiety, atypical anxiety, child characteristics, anxiety predictors and ASD-symptomology were explored. Fifty-nine participants (7–17 years, M_age = 10.48 years; IQ > 60) with ASD and parents completed semi-structured interviews, self- and parent-reports. Seventeen percent of youth presented with traditional anxiety, 15 % with atypical anxiety, and 31 % with both. Language ability, anxious cognitions and hypersensitivity predicted traditional anxiety, whereas traditional anxiety and ASD symptoms predicted atypical anxiety. Findings suggest youth with ASD express anxiety in ways similar and dissimilar to DSM definitions. Similarities support the presence of comorbid anxiety disorders in ASD. Whether dissimilarities are unique to ASD requires further examination.     

A Cost of Illness Study of Children with High-Functioning Autism Spectrum Disorders and Comorbid Anxiety Disorders as Compared to Clinically Anxious and Typically Developing Children

The study’s aim was to estimate the societal costs of children with high-functioning ASD and comorbid anxiety disorder(s) (ASD + AD-group; n = 73), and to compare these costs to children with anxiety disorders (AD-group; n = 34), and typically developing children (controls; n = 87). Mean total costs for the ASD + AD-group amounted €17,380 per year. Societal costs were estimated at almost 142 million euro per year. Costs in the ASD + AD-group were four times higher compared to the AD-group, and 27 times higher compared to controls. ASD-related costs were higher in the ASD + AD-group; anxiety-related costs did not differ between the ASD + AD- and AD-group; costs due to physical or other reasons did not differ across groups. The findings suggest that costs can be decreased if effective treatment options for treating anxiety in ASD are established, however, the remaining costs associated with ASD would still be large. A limitation of the study is that a group of children with ASD without anxiety disorders is lacking.     

Parents’ State and Trait Anxiety: Relationships with Anxiety Severity and Treatment Response in Adolescents with Autism Spectrum Disorders

Comorbid anxiety is common among children with Autism Spectrum Disorder (ASD), and parents of children with ASD are more likely to have anxiety disorders. This study investigated the relationship between parents’ state and trait anxiety and parent-reported internalizing and externalizing symptoms among adolescents (n = 30) with ASD, as well as the relationship of parents’ anxiety symptoms and adolescent treatment response in the context of a randomized controlled trial. Parental state anxiety correlated with severity of adolescent anxiety, and trait anxiety in parents correlated with parent-reported adolescent internalizing and externalizing symptoms. Also, parents of adolescent treatment responders experienced a decrease in their own trait anxiety. Findings highlight the importance of considering parental anxiety when targeting anxiety among youth with ASD.     

Television, Video Game and Social Media Use Among Children with ASD and Typically Developing Siblings

This study examined the nature of television, video game, and social media use in children (ages 8–18) with autism spectrum disorders (ASD, n = 202) compared to typically developing siblings (TD, n = 179), and relative to other activities. Parents completed measures assessing children’s screen-based and other extracurricular activities. Children with ASD spent approximately 62 % more time watching television and playing video games than in all non-screen activities combined. Compared with TD siblings, children with ASD spent more hours per day playing video games (2.4 vs. 1.6 for boys, and 1.8 vs. 0.8 for girls), and had higher levels of problematic video game use. In contrast, children with ASD spent little time using social media or socially interactive video games.     

The Prevalence and Psychopathological Correlates of Sibling Bullying in Children with and without Autism Spectrum Disorder

Using data from a prospective population based study, the prevalence and psychopathological correlates of sibling bullying in children with and without autism spectrum disorder (ASD) were estimated. There were 475 children with ASD and 13,702 children without ASD aged 11 years. Children with ASD were more likely to be bullied by their siblings compared to those without ASD. They were also more likely than those without ASD to both bully and be bullied by their siblings, which was associated with lower prosocial skills as well as more internalizing and externalizing problems compared to those not involved in any sibling bullying. Interventions to improve social and emotional outcomes in children with ASD should focus on both the affected and the unaffected sibling.     

The psychophysiological impact of childhood autism spectrum disorder on siblings

ObjectiveThe negative impact of caring for a child with autism spectrum disorder (ASD) on parents’ psychophysiological functioning has been widely evidenced. However, siblings, who also face emotional, social and physical challenges associated with having a brother/sister with ASD, have been less widely studied. This study examined the psychophysiological impact of childhood ASD on siblings.MethodsA sample of 25 siblings of children with ASD (and their mothers) and a control group of 20 siblings of neuro-typical children (and their mothers) completed questionnaires assessing: (a) demographic and lifestyle information, (b) family characteristics, (c) child behaviour problems, (d) social support and (e) depressive symptomology. Saliva samples were collected at several time points on two consecutive days, and estimates of the cortisol awakening response (CAR), diurnal cortisol slope and mean diurnal cortisol output were derived.ResultsTotal depressive symptoms were higher in siblings of children with ASD compared with controls. Group differences with respect to depressive symptomology were driven more by emotional than functional problems. With respect to physiological functioning, groups were comparable on all cortisol indices. In siblings of children with ASD, social support, especially from parents and close friends, predicted total depressive symptoms, as did the behaviour problems of their brother/sister with ASD.ConclusionSiblings of children with ASD experience greater emotional problems and overall depressive symptoms compared with a control group. Interventions that enhance social support, as well as helping siblings better understand the behaviour problems of their brother/sister with ASD, might be effective for alleviating depressive symptoms.     

Developmental and mental health risks among siblings of patients with autism spectrum disorder: a nationwide study

Studies have suggested that unaffected siblings of patients with autism spectrum disorder (ASD) have some other neurodevelopmental abnormalities. However, the risks of mental and developmental disorders have rarely been investigated among unaffected siblings. Using Taiwan’s National Health Insurance Research Database, 1304 unaffected siblings born between 1980 and 2010 with ASD probands and 13,040 age-/sex-/family structure-matched controls were included in our study and followed up from 1996 or birth to the end of 2011. Developmental delay, language delay, developmental coordination disorder, attention-deficit hyperactivity disorder (ADHD), anxiety disorders, disruptive behavior disorders, unipolar disorder, and bipolar disorder were identified during the follow-up period. Unaffected siblings were more likely to develop any developmental delay, developmental speech or language disorder, developmental coordination disorder, intelligence disability, ADHD, anxiety disorders, unipolar depression, and disruptive behavior disorders compared with the control group. Brothers of patients with ASD had a higher risk of neurodevelopmental abnormalities, ADHD, anxiety disorders, and disruptive behavior disorders; sisters were prone to having neurodevelopmental abnormalities, ADHD, anxiety disorders, unipolar depression, and disruptive behavior disorders. Unaffected siblings of patients with ASD were prone to developing any developmental or mental disorder later in life. Clinicians and public health officials should pay more attention to the developmental condition and mental health of unaffected siblings of patients with ASD.

     

A Survey of Out-of-Pocket Expenditures for Children with Autism Spectrum Disorder in Israel

We describe a survey of children with ASD aged 4–10 years. The main dependent variables were out-of-pocket expenditures for health services and hours of therapy. Multivariable logistic regression models were used in order to find independent predictors for service utilization. Parents of 178 of the children (87 %) agreed to participate. The average annual out-of-pocket cost was $8,288, with a median of $4,473 and a range of $0-89,754. Higher severity of ASD and a parent with an academic degree were associated with higher expenditure. Having at least one older sibling, siblings without developmental disorders, regular education setting, lower parent education and low income were associated with lower expenditure.     

The Sex Ratio of Full and Half Siblings of People Diagnosed with an Autism Spectrum Disorder: A Danish Nationwide Register Study

In the extreme male brain theory of autism sex steroid hormones are hypothesized to influence brain development and to mediate sex differences in developmental psychopathology. Within this scope we examined the sex ratio (proportion of males) in siblings of individuals diagnosed with autism spectrum disorders (ASD). We did a nationwide, register based cohort study of the sex ratio in 17,380 siblings of the 10,297 patients diagnosed with ASD at age 17 years and younger and registered in the nationwide Danish Psychiatric Central Register between 1994 and 2012. Among the 17,380 siblings 8,828 were males and 8,552 females. This yields a sex ratio of 0.508, which is not different from the Danish live birth sex ratio of 0.513 during the relevant years (P = 0.18). Overall, our findings provide no support for the hypothesis that there are relatively more males among the siblings of people with ASD. Accordingly, our results do not give support to the extreme male brain theory of autism.     

Psychiatric Comorbidity and Functioning in a Clinically Referred Population of Adults with Autism Spectrum Disorders: A Comparative Study

To systematically examine the patterns of psychiatric comorbidity and functioning in clinically referred adults with autism spectrum disorders (ASD). Psychiatrically referred adults with and without ASD were compared on measures assessing for psychiatric comorbidity and psychosocial functioning. Sixty-three adults with ASD participated in the study (mean age: 29 ± 11 years). Adults with ASD in their lifetime suffered from a higher burden of psychiatric disorders (6 ± 3.4 vs. 3.5 ± 2.7; p < 0.001) including major depressive disorder and multiple anxiety disorders, and were functionally more impaired with a significant proportion having received both counseling and pharmacotherapy. Adults with ASD have high levels of psychiatric comorbidity and dysfunction comparable to a clinically referred population of adults without ASD.     

Social Anxiety in Parents of High-Functioning Children with Autism and Asperger Syndrome

We evaluated social anxiety (SA) symptoms in parents of children with autism spectrum disorders (ASDs; N = 131) and community parents (N = 597) using the Social Phobia and Anxiety Inventory (SPAI). SA was significantly more common in ASD than control mothers (15.6 vs. 6.7 %) and more equal between the ASD and control fathers (3.3 vs. 4.8 %). The ASD mothers scored significantly higher than control mothers on all SPAI scales. ASD fathers scored significantly higher than control fathers on the somatic, cognitive, avoidance and agoraphobic symptoms of SA. It is of clinical import to support ASD parents’ well-being as their psychiatric features may contribute greatly to their children’s emotional development and the well-being of the whole family.     

Psychopathology in Children and Adolescents with ASD Without Mental Retardation

This study analyzes subclinical psychopathology in children and adolescents with autism spectrum disorders (ASD) without mental retardation with no comorbid disorder, assessed by an extensive general psychopathology interview. The K-SADS-PL was administered to a group of 25 patients with ASD (mean age = 12.80 ± 2.86 years) and 25 healthy controls (mean age 12.52 ± 2.86 years). Significant differences were found between patients with ASD and controls for the domains of: depressive disorder, anxiety separation disorder, agoraphobia and specific phobias, obsessive compulsive disorder (OCD), and attention deficit hyperactivity disorder (ADHD). In patients without a comorbid disorder, we found a profile of subclinical disturbances that suggest high risk for comorbid psychiatric conditions derived from the presence of subthreshold symptomatology.     

Being on Your Own or Feeling Lonely? Loneliness and Other Social Variables in Youths with Autism Spectrum Disorders

A cross-sectional study was conducted to examine loneliness and its correlates in children (7 to 11 years) and adolescents (12 to 18 years) with autism spectrum disorders (ASD, n?=?73) and control groups of clinically referred (ADHD, n?=?76) and non-clinical (n?=?106) youths. Youths completed questionnaires on loneliness and desire for social interaction, while parents and teachers filled out scales on other aspects of children’s social functioning. Results indicated that only at an adolescent age, the ASD group reported higher levels of loneliness than the control groups. Further, the ASD group generally expressed relatively low levels of desire for social interaction, although these youths displayed a similar increase in the wish to belong during adolescence as participants in the control groups. Finally, the ASD group exhibited lower levels of social competence and social skills and higher levels of social problems and social anxiety than the control groups, and in all groups these social variables correlated in a theoretically meaningful with loneliness.     

Neuroglobin Protects Rats from Sepsis-Associated Encephalopathy via a PI3K/Akt/Bax-Dependent Mechanism

The pathogenesis of autism spectrum disorders (ASD) is not completely understood, but there is evidence of associations with altered immune responses. The aim of this study was to determine the serum levels of various cytokines in children with ASD and in healthy controls, in order to determine their role in ASD and its diagnostic subgroups. Sixty-five ASD patients were enrolled from an epidemiological survey in Norway, of which 30 were diagnosed with childhood autism, 16 with Asperger syndrome, 12 with atypical autism, 1 with Rett syndrome, and 6 with another ASD diagnosis. The serum levels of 12 cytokines were measured in all of the patients and in 30 healthy children. The cytokine levels did not differ significantly between the ASD group and the healthy controls. However, the interleukin-8 (IL-8) level was significantly higher (6.82 vs 4.58 pg/ml, p?=?0.017) while that of IL-10 was significantly lower (2.24 vs 6.49 pg/ml, p?=?0.009) in patients with childhood autism than in controls. Furthermore, the IL-8 level was significantly higher in childhood autism than in Asperger syndrome (6.82 vs 4.05 pg/ml, p?=?0.013). Our study shows that the cytokine profile of children diagnosed with ASD, regardless of the subdiagnosis, does not differ from healthy controls. However, differentiation into different diagnostic subgroups reveals significantly different levels of IL-8 and IL-10. This indicates that different mechanisms may underlie the different ASD subdiagnoses. Future research into the pathophysiological mechanisms of ASD should pay more attention to the different subdiagnoses of ASD.     

Participation in extracurricular activities for children with and without siblings with autism spectrum disorder

Objective: To compare the number, frequency, enjoyment and performance in extracurricular activities of siblings of children with autism spectrum disorders (ASD) to their typically developing (TD) peers, and to identify differences between actual and desired participation. Methods: A case-control study with 30 siblings of children with ASD and 30 siblings of TD children was conducted using the Paediatric Interest Profiles and a questionnaire. Results: Siblings of children with ASD participated in fewer extracurricular activities than those with TD siblings. ASD symptoms were significantly associated with the sibling participating in fewer extracurricular activities. Children with TD siblings had higher enjoyment scores in relaxation activities than children with siblings with ASD. Conclusion: While results were mainly positive, some differences indicated that having a sibling with ASD may impact participation in extracurricular activities. Assessments of participation barriers, as well as support to minimise participation restrictions among siblings of children with ASD are required.     

Parental reports on the use of treatments and therapies for children with autism spectrum disorders

Parents of children with autism spectrum disorders (ASD; N = 479) reported via web-based survey what pharmacological (drug), diet, and behavioral/educational/alternative therapies they had tried and were using now in the treatment of their children with ASD. Depending on type of ASD, children had tried, on average, between seven and nine therapies and were now using between four and six. Children with Asperger's syndrome had tried significantly more drug treatments than had those with autism or PDD-NOS, while those in these latter two groups had tried more behavioral/educational/alternative therapies. Adolescents had a higher prevalence of drug-treatment use compared with those in middle childhood, who, in turn, had a higher frequency of use relative to those in early childhood. For most behavioral/educational/alternative treatments, more children in early and middle childhood had tried them compared with adolescents. Likewise, children in both early and middle childhood were currently using a higher number of behavioral/educational/alternative treatments than were those in the adolescent group. Findings are discussed relative to both the extant literature on treatment use among ASD families and how parents choose among the plethora of available therapies.     

Refractive Status and Amblyopia Risk Factors in Chinese Children with Autism Spectrum Disorder

Amblyopia risk factors in children with autism spectrum disorders (ASD) are usually hard to detect in early childhood due to poor cooperation and has not been reported in the Chinese population. We screened 168 Chinese children with ASD, aged between 3 and 8 years, and 264 age-matched neurotypical children with Spot photoscreener and basic ophthalmologic examinations. Children with ASD were found to have normal refractive status but significantly higher incidence of strabismus (16.1%), compared with control children (1.5%) (p?<?0.01). Most of the cases of strabismus found in children with ASD were classified as esodeviation. Strabismus in children with ASD should be considered more seriously as an amblyopia risk factor by ophthalmologists and other healthcare professionals.
