Cross-cultural differences in the Parent Rated Social Responsiveness Scale (SRS)? Evaluation of the Finnish version among high-functioning school aged males with and without autism spectrum disorder

When importing screening questionnaires of ASD, it has been found that parental interpretation/reporting of autistic traits may be culturally influenced. In the current study, our aim was preliminary evaluation of the Finnish parent rated SRS in order to determine whether the measure would show promise as an aid in screening. The study sample consisted of high-functioning school aged male ASD outpatients of Oulu University Hospital (n = 44, age 11.4 ± 2.3) and age-matched controls (n = 44, age 11.8 ± 2.4 years). Internal consistency as well as convergent and discriminative validity was in line with previous research. However, the results indicated that the cut-off published in the SRS manual might be too high to be used in Finland. Our results emphasize the importance of determining the normative range and clinical cut-offs in various cultures when importing diagnostic screening questionnaires in order to avoid getting high percentages of false negatives in the screening phase, and thus risk leaving many children without adequate diagnostic evaluation and rehabilitation.     

Validation of Social Responsiveness Scale for Korean Preschool Children With Autism

ObjectiveThis cross-cultural study aims to examine the psychometric properties of the Social Responsiveness Scale (SRS) and to determine the best-estimate-cut-off scores for the diagnosis of autism spectrum disorder (ASD) in Korean preschool children. MethodsA total of 563 children was recruited from multiple sources, including Seoul National University Bundang Hospital. Participants were assessed by a multidisciplinary research team using multiple diagnostic tools based on DSM-5 diagnostic criteria. Discriminative validity was tested by comparing the difference in SRS scores between ASD and non-ASD groups. Convergent validity was tested by examining correlations between SRS scores with other diagnostic instruments. A receiver operation characteristic curve analysis was conducted to test the sensitivity and specificity of SRS and to determine the best-estimate-cut-off scores for screening ASD in Korean preschool children. ResultsThere were significant differences in the total SRS scores between the ASD (n=242) and non-ASD group (n=321) (p<0.01, 95% confidence interval [CI]: 14.08–17.24). The differences were significant even after adjusting for age. SRS scores were significantly correlated with other prescreening diagnostic tools for ASD. The best-estimate cut-off score to screen ASD was 55 (area under curve=0.88, sensitivity 78.1%, specificity 86.6%).ConclusionThe SRS is a valid and reliable instrument to screen and aid in the diagnosis of ASD in Korean preschool children. The adjusted cut-off scores, notably lower than in the original U.S. version, may yield a more accurate diagnosis by reflecting transcultural differences.     

Relationship of autistic traits between parents and children with and without autism spectrum disorder

BackgroundAlthough parents with a child with autism spectrum disorder (ASD) have usually been identified as having the “broader autism phenotype”, empirical research on the differences in autistic-like characteristics between parents with and without ASD children has yielded inconsistent results.MethodThis survey of the autistic traits of parents and children was conducted in 119 parents with ASD children and 108 parents with typically developing (TD) children. Parents’ autistic traits were quantified using the Autism-Spectrum Quotient and children’s autistic traits were quantified using the Autism Spectrum Quotient—Children’s Version.ResultsThe autistic traits of ASD children were significantly higher than those of the TD children; however, autistic traits were similar between parents in the two groups. Furthermore, the correlations of autistic traits between parents and children were only significant for the TD group and not for the ASD group.ConclusionsThe current findings indicate that the relationship of autistic traits between parents and children exists in the TD group, and that the Autism-Spectrum Quotient may be used for parents as a screening aid to identify children who should be further screened for autistic traits.     

When does the Autism Spectrum Screening Questionnaire (ASSQ) predict autism spectrum disorders in primary school-aged children?

The aims of this study were, firstly, to study the association between parents’ and teachers’ ratings for the Finnish version of the Autism Spectrum Screening Questionnaire (ASSQ), secondly, to find out whether the original cut-off scores of the ASSQ identify primary school-aged children with Asperger syndrome (AS) or autism by using the Finnish ASSQ, and thirdly, to evaluate the validity of the ASSQ. Parents and/or teachers of higher-functioning (full-scale intelligence quotient ≥ 50) 8-year-old total population school children (n = 4,408) and 7–12-year-old outpatients with AS/autism (n = 47) completed the Finnish version of the ASSQ. Agreement between informants was slight. In the whole total population, low positive correlation was found between parents’ and teachers’ ratings, while in the sample of high-scoring children the correlation turned out to be negative. A cut-off of 30 for parents’ and teacher's summed score and 22 for teachers’ single score is recommended. A valid cut-off for parents’ single score could not been estimated. The clinicians are reminded that the ASSQ is a screening instrument, not a diagnosing instrument. The importance of using both parents’ and teachers’ ratings for screening in clinical settings is underlined.     

Validity of the Social Communication Questionnaire in Assessing Risk of Autism in Preschool Children with Developmental Problems

This study estimates the sensitivity and specificity of the social communication questionnaire (SCQ) for autistic spectrum disorders in preschool children at high risk for developmental problems referred to a tertiary centre and compares the predictions of the SCQ and the referrer. The SCQ was completed by 81 parents prior to multidisciplinary assessment and compared with the final diagnosis. The sensitivity and specificity were 93% and 58% for children aged 2–6, and 100 and 62% for children aged 3–5 years, with a cut-off score of 11. The SCQ performed better than referrers. Low-specificity means the SCQ is not suitable as a diagnostic tool but will assist clinicians and tertiary services in selecting children with developmental problems who require autism-specific assessment.     

Autism spectrum disorders in children with seizures in the first year of life - a population-based study

PURPOSE: To describe autistic spectrum disorders (ASDs) in a cohort of children with history of unprovoked seizures other than infantile spasms in the first year of life. METHODS: The source of data was computer records from all the three pediatric departments in Iceland. Children diagnosed 1982-2000 with unprovoked seizures with onset between 28 days and 12 months of age (N = 102) were invited to participate in a study. Children with known developmental disorders and those whose parents had concerns regarding their child's development or behavior were investigated for possible ASD. Parents were asked to complete the Social Communication Questionnaire and children scoring 10 points or higher were further examined with the Autism Diagnostic Interview-Revised and observational measures. RESULTS: Eighty-four children (82.4%), 28 boys and 56 girls, participated in the study and 36.9% (31/84) were investigated for possible ASD. Twenty-four (28.6%) had at least one neurodevelopmental disorder, 14.3% had mental retardation (MR), and six (7.1%) were diagnosed with ASD, all of whom also had MR and three of whom had congenital brain abnormalities. CONCLUSION: These results suggest that the estimated prevalence of ASD is higher in children with history of seizure in the first year of life than it is in the general population. There are indications that support the view that children with ASD and history of seizure in the first year of life have higher prevalence of congenital brain abnormalities and are more often female, than other children with ASD.     

Externalizing and tantrum behaviours in children with ASD and ADHD compared to children with ADHD

Objective: Compare rates of externalizing in children with autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD) symptoms to children with ADHD.

Method: Parents/caregivers of 85 children with ASD and/or ADHD were surveyed about their children's behaviours using the Autism Spectrum Disorders-Comorbidity for Children and the Autism Spectrum Disorders-Behaviour Problem for Children.

Results: Specific main effects analyses were then conducted. Children with ASD exhibited a higher number of externalizing (F(1,?83)?=?83.34, p?<?0.001) and tantrum behaviours (F(1,83)?=?781.86, p?<?0.001) than children without ASD.

Conclusions: ASD exacerbates the externalizing symptoms of ADHD during childhood. This study adds to the literature on the importance of assessing for a wide-range of possible behaviour problems in children presenting with ADHD symptomatology. The implications of these findings are discussed in the context of other research.     

The inclusion of fathers in investigations of autistic spectrum disorders

Recent reviews indicate an underrepresentation of fathers in empirical investigations of child development and psychopathology (Cassano et al., 2006, Phares et al., 2005). The purpose of the current study was to examine the nature of parental involvement in research on children with autistic spectrum disorders (ASD). Articles published over the last decade from journals with the highest impact factors in disciplines relevant to the study of ASD were reviewed, including areas of psychiatry, developmental psychopathology, and developmental disabilities. A total of 404 articles were included in the review and were coded to determine if parental inclusion and method of statistical analysis varied as a function of child age, journal type, year of publication, and parent gender. Results were consistent with findings from recent reviews and indicated that fathers are widely underrepresented in the literature on ASD, even more so than rates of inclusion in investigations of developmental and child clinical psychology. In contrast to findings from broad reviews of parental inclusion in studies of child psychopathology, fathers’ involvement was not higher in older versus younger age of child participant. Clinical implications and recommendations to improve inclusion rates of fathers in research on children with ASDs are discussed.     

Assessing Need for Social Support in Parents of Children with Autism and Down Syndrome

Parents of children with autism frequently turn to the service delivery system to access supports designed to help adapt to the challenges of having a child with a life-long impairment. Although studies have suggested various supports and coping strategies that are effective for adapting, few studies have examined parents’ own perceptions of needs, and whether parents felt their needs were being met. In the present study the Family Needs Questionnaire (FNQ; Waaland et al., 1993) was modified to address needs for children with developmental disorders. A sample of fifty-six parents of children with autism and a comparison group of thirty-two parents of children with Down syndrome completed the FNQ. The groups did not differ significantly on the number of important needs reported nor the number of important needs being met. However, the two groups differed in the types of supports they most frequently endorsed as Important or Unmet.     

Chaotic family environments and depressive symptoms in parents of autistic children: The protective role of optimism

BackgroundRaising an autistic child is associated with increased parenting stress and higher rates of depression for both mothers and fathers. While most research has focused on the challenges related to having an autistic child, such as higher rates of chaotic family environments, an emerging body of research has begun to examine the protective effects of optimism to reduce the negative impact on parent mental health.MethodA total of 133 mothers and 78 fathers of autistic children between the ages of 2–10 years participated in the study. Parents answered questionnaires related to their family functioning, dispositional optimism, and depressive symptoms.ResultsResults found a significant family chaotic environment X optimism X parent gender interaction. For mothers and fathers, higher levels of chaotic family environment were associated with increased depressive symptoms whereas increased levels of optimism were associated with lower levels of depressive symptoms. However, optimism was only protective for mothers and not for fathers.ConclusionsThe results highlight the need for the inclusion of optimism in parent-focused interventions.     

Rates of psychotropic medication use in children with ASD compared to presence and severity of problem behaviors

There is a scarcity of research on the relationship between presence of problem behaviors and psychotropic medication use in children with autism spectrum disorder (ASD). Participants in the current study were children and adolescents ages 3–17 years who were sorted into four groups: ASD on psychotropic medication (N = 100), ASD not on psychotropic medication (N = 147), typically developing on medication (N = 48), and typically developing not on medication (N = 168). A one-way multivariate analysis of covariance (MANCOVA) was conducted to determine the relationship between medication use and rates of internalizing and externalizing behaviors. Post hoc analyses revealed that children with ASD on psychotropic medication evinced significantly more externalizing behaviors than children with ASD not on medication. However, the two groups did not significantly differ on rates of internalizing behaviors. These results suggest that psychotropic medications may often be prescribed to manage externalizing behaviors. Implications of these findings are discussed in relation to the existing literature.     

Friendship interventions and measurements in children with ASD: A systematic review

BackgroundFriendships are vital to children's social well-being and overall development, and they can also serve as a protector factor from peer victimization and bullying. For children with ASD, friendship development can be an area of challenge. Friendship interventions may help children and adolescents with ASD in developing the skills for making and keeping friends.MethodThis systematic review examined friendship interventions for children and adolescents with autism spectrum disorder (ASD). It also explored measures of friendship skills in children with ASD. Twenty-seven studies met the inclusion criteria: (a) experimental intervention studies focused on improving friendships of individuals with ASD, (b) the measurement of friendship outcomes, and (c) strong or acceptable methodological ratings.ResultsFifteen unique interventions were tested across the 27 studies. Thirteen interventions included strategies specifically focused on improving (making and maintaining) friendships in the participants with ASD. Friendship interventions were primarily focused on behaviorally based social skills building and varied in implementation settings. Friendship measures included the use of parent reports, child and adolescent surveys and questionnaires, peer nominations, and sociometric ratings.ConclusionThe results highlighted the benefit of including targeted friendship-building strategies in social and friendship interventions and the value of multiple perspectives when measuring friendship. The findings of the study can influence how families and practitioners collaborate to support children and adolescents with ASD in the development and maintenance of their friendships.     

Parent-reported problematic sleep behaviors in children with comorbid autism spectrum disorder and attention-deficit/hyperactivity disorder

BackgroundSleep problems are frequent and well documented in children with Autism Spectrum Disorders (ASD), children with Attention Deficit/Hyperactivity Disorder (ADHD) and children with internalizing problems, however limited work has examined sleep problems in children presenting with comorbid ASD/ADHD. In healthy children, sleep problems negatively impact social, emotional, and academic functioning. The current study sought to examine diagnostic severity as predictors of sleep problems in children with comorbid ASD/ADHD. Additionally, the association between sleep and “real-life” functional domains (i.e., intellectual functioning, academic achievement, and executive functioning) were assessed.MethodSleep, internalizing difficulties, intellectual functioning, academic achievement and executive functioning were assessed in 85 children with who carried the dual diagnoses of ASD and ADHD.ResultsInternalizing difficulties, rather than ASD or ADHD symptom severity, was the most consistent predictor of problematic sleep behaviors (i.e., nightmares overtiredness, sleeping less than other children, trouble sleeping, and Total Problematic Sleep Behaviors) in this sample. Further, parent report of problematic sleep behaviors was significantly associated with functional domains after controlling for ASD, ADHD, and internalizing symptoms.ConclusionsResults suggest that internalizing symptoms are associated with problematic sleep behaviors in children with comorbid ASD/ADHD and may have implications for the “real-life” functioning among children with comorbid ASD/ADHD.     

Role of hedgehog protein family members in autistic children

BackgroundThe neurological basis for autism is still not fully understood, and the role of the interaction between hedgehog (hh) protein family members, Sonic hedgehog (Shh), Indian (Ihh), and Desert (Dhh) biological activities have not been previously undertaken in autism spectrum disorder (ASD).MethodsSerum levels of Shh, Ihh and Dhh were determined in the plasma of 57 Saudi patients, categorized as mild-moderate and severe as indicated by their Childhood Autism Rating Scale (CARS) and compared to 27 age- and gender-matched control samples.ResultsThe data indicated that autistic children had higher serum levels of Shh (P = 0.001), Ihh (P = 0.001) and lower level of Dhh (P = 0.003) than those of normal controls. Moreover, serum levels of Shh had significant positive correlations with Dhh (P < 0.002).ConclusionsThis study suggests that higher levels of Shh, Ihh and lower Dhh levels may play a role in the pathophysiology of autism.     

The prevalence of autistic spectrum disorder in children surveyed in a tertiary care epilepsy clinic

It is well documented that children with autistic spectrum disorder (ASD) have an increased prevalence of seizures; however, studies have not been done to evaluate the prevalence of ASD in children with epilepsy. This comorbidity is important to define as early diagnosis and intervention in some children with ASD has been shown to improve outcome. METHOD: Children with epilepsy seen in a tertiary care epilepsy clinic were evaluated using validated autism screening questionnaires (ASQ). In addition, questions about sleep-related disorders, behavior, seizure characteristics, antiepileptic agents, and body mass index (BMI) were requested. An attempt was then made to determine if there was a correlation between the factors identified and ASD. RESULTS: Of the 107 questionnaires returned, 97 ASQ's were properly completed and used in this study. Approximately 32% of children fit the ASQ criteria for having ASD. Most children had not been previously diagnosed. Worst behavior and daytime sleepiness was seen in those at greater risk (p < 0.01). Seizures also occurred earlier (approximately 2 years) in children at risk of having ASD. CONCLUSION: Though confirmatory diagnostic evaluations are needed, this questionnaire-based study suggests that children with epilepsy are at greater risk of having ASD, and illustrates the need for more clinical vigilance. Behavioral difficulties and daytime sleepiness identified in these children could potentially affect their ability to learn. It is of interest that the age of seizure onset identified in those at greater risk corresponds with the approximate age of regression identified in some children with ASD.     

Psychometric properties of the French Version of the Social Responsiveness Scale in autism spectrum disorder with or without attention deficit hyperactivity disorder

ObjectivesThe Social Responsiveness Scale (SRS) is an instrument that is commonly used to screen for Autism Spectrum Disorder (ASD). Attention Deficit Hyperactive Disorder (ADHD) frequently occurs with ASD and both disorders share some phenotypic similarities. In the present study, we aimed to determine the psychometric properties of the French version of the Social Responsiveness Scale (SRS) and its 5 subscales (social awareness, social cognition, social communication, social motivation, and autistic mannerisms) to discriminate between children with ADHD and those with ASD (differential diagnosis) and children with ADHD from those with a dual diagnosis of ADHD and ASD (comorbid diagnosis).MethodSRS total scores and the 5 subscores of the SRS were compared between 4 groups of children: ADHD (n = 32), ASD + ADHD (n = 30), ASD (n = 31) and typical neurodevelopment (TD; n = 30) children. The discriminant validity was estimated using the Area Under the ROC Curves (AUC).ResultsSRS Social cognition (AUC = 0.73) and Autistic mannerisms (AUC = 0.70) subscores were the most discriminating for differential diagnosis of ASD and ADHD. SRS total scores (AUC = 0.70), and Social communication (AUC = 0.66) and Autistic mannerisms (AUC = 0.75) subscores were the most discriminating for comorbid diagnosis of ASD among ADHD children.ConclusionThe SRS autistic mannerisms subscore was found to be clinically relevant for both differential diagnosis of ASD and ADHD and comorbid diagnoses of ASD among ADHD children but with a modest discriminant power.     

A pilot study of combining social skills training and parenting training for children with autism spectrum disorders and their parents in Japan

The purpose of this study is to investigate the effects of a program containing a combination of social skills training (SST) and parenting training (PT) for the enrichment of social interaction skills and reduction of parenting stress for children with high-functioning autism spectrum disorder (HFASD) and their parents in Japan. Twenty-two patients with HFASD from second to fourth grade and their parents were assigned to a training group (TG) or treatment as usual (TAU) and compared. The children with HFASD and their parents who were assigned to the TG participated in the manualized program for over a period of five to six months. Subjects provided demographic and medical information and completed teacher and parent-rating scales for social competence (Social Responsiveness Scale-2: SRS-2) and parent-rating of parenting stress (Parental Stress Index: PSI) and mental health (General Health Questionnaire-28: GHQ-28). The participants exhibited some improvements pre-, middle-, and post-treatment, particularly regarding the GHQ, PSI and SRS-2, as reported by parents. However, the social skills improvement reported by teachers was not significant. At the three-month follow-up, parent-rated GHQ and PSI maintained improvement, and SRS-2 achieved the greatest improvement from the baseline rating. Although some findings indicate that a program combination of SST and PT might be useful for enhancing social skills and improving parental stress and mental health, some subscales did not show a sufficient effect. Future research should consider program contents and provide longitudinal follow-up data to test the durability of the treatment.     

Autism spectrum disorder symptoms in children with ADHD: A community-based study

This study examined the prevalence of autism spectrum disorder (ASD) symptoms in a community-based sample of children with attention-deficit/hyperactivity disorder (ADHD) and non-ADHD controls. We also examined the relationship between ASD symptoms and ADHD subtype, ADHD symptom severity and child gender. Participants were 6–10-year-old children (164 ADHD; 198 non-ADHD control) attending 43 schools in Melbourne, Australia, who were participating in the Children's Attention Project. ADHD was assessed in two stages using the parent and teacher Conners’ 3 ADHD index and the Diagnostic Interview Schedule for Children IV (DISC-IV). ASD symptoms were identified using the Social Communication Questionnaire (SCQ). Unadjusted and adjusted linear and logistic regression examined continuous and categorical outcomes, respectively. Children with ADHD had more ASD symptoms than non-ADHD controls (adjusted mean difference = 4.0, 95% confidence interval (CI) 2.8; 5.3, p < 0.001, effect size = 0.7). Boys with ADHD had greater ASD symptom severity than girls with ADHD (adjusted mean difference = 2.9, 95% CI 0.8; 5.2, p = 0.01, effect size = 0.4). Greater ADHD symptom severity was associated with greater ASD symptom severity (regression co-efficient = 1.6, 95% CI 1.2; 2.0, p < 0.001). No differences were observed by ADHD subtype. Greater hyperactive/impulsive symptoms were associated with greater ASD symptoms (regression coefficient = 1.0; 95% CI 0.0; 2.0, p = 0.04) however, this finding attenuated in adjusted analyses (p = 0.45). ASD symptoms are common in children with ADHD. It is important for clinicians to assess for ASD symptoms to ensure appropriate intervention.     

Preschool predictors of school-age academic achievement in autism spectrum disorder

Abstract

Objective: Characterization of academic functioning in children with autism spectrum disorder (ASD), particularly predictors of achievement, may have important implications for intervention. The current study aimed to characterize achievement profiles, confirm associations between academic ability and concurrent intellectual and social skills, and explore preschool predictors of school-age academic achievement in a sample of children with ASD. Method: Children with ASD (n = 26) were evaluated at the approximate ages of two, four, and ten. Multiple regression was used to predict school-age academic achievement in reading and mathematics from both concurrent (i.e. school-age) and preschool variables. Results: Children with ASD demonstrated a weakness in reading comprehension relative to word reading. There was a smaller difference between mathematics skills; math reasoning was lower than numerical operations, but this did not quite reach trend level significance. Concurrent IQ and social skills were associated with school-age academic achievement across domains. Preschool verbal abilities significantly predicted school-age reading comprehension, above and beyond concurrent IQ, and early motor functioning predicted later math skills. Conclusions: Specific developmental features of early ASD predict specific aspects of school-age achievement. Early intervention targeting language and motor skills may improve later achievement in this population.
