RESUMEN
BACKGROUND: Comorbid conditions are very common in children and adults with autism spectrum disorder (ASD) and can affect school performance, adaptive skills and peer relationships. Comorbid conditions place strain on the family as well as the individual with ASD. This project aimed to determine the affect of comorbid conditions over and above child and family characteristics. METHODS: The present authors examined 3,055 cases of children with ASD who had varying numbers of comorbid conditions (i.e., ADHD, depression, anxiety or behaviour problems). RESULTS: Multiple comorbid conditions did have a unique impact on difficulties accessing services. A greater number of comorbid conditions impacted daily activity participation, but not a family's receipt of mental health care or respite, work changes or number of weekly hours dedicated to caring for a child with ASD. CONCLUSIONS: Families, practitioners, paraprofessionals and educators of children with autism should address comorbid conditions to ensure both child and family well-being.

Many youth with autism spectrum disorder (ASD) experience co-occurring conditions, such as gastrointestinal (GI) problems and internalizing symptoms. However, the relationship among these co-occurring problems is not well-understood. We analyzed parent reports of GI problems and internalizing symptoms of 621 youth with ASD using path models in a structural equation modeling framework. The best-fitting model was a bidirectional model wherein internalizing symptoms, including withdrawn and anxious behavior, were correlated with GI problems, including constipation, diarrhea, nausea, and stomach pain. This study provides a better understanding of the relationship among co-occurring conditions in youth with ASD and should encourage clinicians to consider treatment of underlying internalizing symptoms or GI problems when providing services for individuals with ASD.

Up to 80% of children with autism spectrum disorder (ASD) experience sleep problems, which have been associated with more severe presentations of ASD symptoms. We examined the bidirectional link between sleep problems and specific ASD symptoms at two time points within 5 years in a well-characterized sample (659 children with ASD). Using cross-lagged panel analyses, we found evidence for a unidirectional link between baseline ASD symptoms (specifically repetitive behaviors, atypical behaviors, communication, and peer interactions) and future sleep problems, but did not find evidence of a bidirectional relationship. We did not find any longitudinal association between social reciprocity and sleep problems. It is important for providers and caregivers to understand and monitor the link between ASD symptoms and sleep problems.

BACKGROUND: Evaluation of children with autism spectrum disorder (ASD) includes caregiver-reported rating scales of symptom presentation. The extent to which a broad autism phenotype (BAP) in parents of children with ASD might impact their endorsement of autism symptoms in their children with and without ASD has not been well evaluated. AIMS: This study analyzed whether varying degrees of parental BAP were associated with reported autism symptoms in offspring with and without ASD. METHODS AND PROCEDURES: We used the Broad Autism Phenotype Questionnaire as a measure of BAP in parents and parent- and teacher-report on the Social Responsiveness Scale (SRS) to assess autism symptoms in children with ASD and their typically developing (TD) siblings (N = 5714). We assessed the relationship between parental BAP and parent-teacher discordance. We compared teacher reports of autism symptoms in children with varying degrees of BAP exposure. OUTCOMES AND RESULTS: Mothers with higher levels of BAP over-reported autism symptoms in their children (compared to teachers) than mothers with lower BAP. TD children from parents with greater BAP displayed more autism symptoms than children from households with less BAP. CONCLUSIONS AND IMPLICATIONS: BAP is associated with parent report of autism symptoms when compared to teacher report. For children with ASD, it is possible that differences in ratings reflect parent perception and not autism symptomatology; whereas, TD children from households with higher levels of BAP exposure showed more phenotypic autism symptom presentation on teacher-completed measures. Researchers and clinicians should consider BAP when interpreting caregiver and teacher reports.

Subclinical levels of autism traits are known as the Broad Autism Phenotype (BAP) and include a rigid personality, aloof personality, and pragmatic language difficulties. Genetic relatives of children with autism spectrum disorder (ASD), males, and those in math- or science-oriented careers may be more likely to exhibit BAP. This study examined the prevalence of BAP in young adults to assess the influence of genetic relationship to ASD, gender, and academic field. Online self-report data from 170 undergraduate college students included the Broad Autism Phenotype Questionnaire (BAPQ), information about genetic relationship to ASD, and demographic information. Results showed no relationship between BAP and level of shared ASD genes, gender, or academic major. However, 25.3% of our college-aged sample met BAP cutoffs, compared to previous estimates of only 5-9% of adult parents of neurotypical children and 14-23% of parents of children with ASD. These findings expand our understanding of subclinical autistic traits in young adults. This research highlights the need to investigate community-based samples of various age groups when estimating the prevalence of BAP to better-understand the extent to which these personality characteristics are present in the general population.

Background: Children with intellectual disability are at risk for anxiety disorders involving intense physiological reactions and risky behavioral responses. Interventions have been identified in this field; however, assessment of underlying anxiety is limited and flawed.Method: We implemented a single-subject case study using differential reinforcement to treat dog phobia in a boy with intellectual disability. We recorded elopement and compliance with goals and measured physiological expressions of stress: galvanic skin response, heart rate variability, temperature, and latency to calm down.Results: After fifteen therapy sessions, the boy decreased elopement and noncompliance considerably and showed dramatic improvements in emotional self-regulation.Conclusions: Future research should examine the utility of including biosensing measures in clinical applications and the relationship between physiological measures of anxiety and traditional questionnaires. Children with intellectual disability at risk for anxiety disorders should be tracked longitudinally to examine the effect of interventions on social-emotional well-being and self-regulation.

Social interaction difficulties in children with autism spectrum disorder can be challenging, especially during adolescence. In addition, high rates of comorbid internalizing disorders in autism spectrum disorder can lead to social isolation. With limited social activity participation, social deficits and internalizing problems in autism spectrum disorder may be related to participation, exposure, and practice with friends. The purpose of this study was to evaluate the relations among friendship, activity participation, and internalizing problems. Participants included 129 children with autism spectrum disorder between the ages of 6 and 18 years. Measures of friendship, sport, hobby, and club participation, and internalizing problems were assessed. Results showed that activity participation was related to more friendships, even after controlling for intelligence quotient. This study sheds light on the impact of social engagement with peers in developing and maintaining friendships as well as managing internalizing problems.

Background: Many individuals with autism spectrum disorder (ASD) have co-occurring gastrointestinal (GI) symptoms, but the etiology is poorly understood. These GI symptoms often coincide with problem behaviors and internalizing symptoms, which reduces the quality of life for these individuals. Methods: This study examined the relationships among GI problems, problem behaviors, and internalizing symptoms in a sample of 340 children and adolescents with ASD who are patients at the University of Missouri Thompson Center for Autism & Neurodevelopmental Disorders. Results: The majority of patients experienced constipation (65%), about half experienced stomachaches or stomach pain (47.9%), and others experienced nausea (23.2%) or diarrhea (29.7%). Young children with aggressive problem behaviors were 11.2% more likely to have co-occurring nausea; whereas, older children showed more complex relationships between internalizing symptoms and GI symptoms. Older children with greater anxiety symptoms were 11% more likely to experience constipation, but 9% less likely to experience stomachaches. Older children with greater withdrawn behavior were 10.9% more likely to experience stomachaches, but 8.7% less likely to experience constipation. Older children with greater somatic complaints were 11.4% more likely to experience nausea and 11.5% more likely to experience stomachaches. Conclusions: Results suggest that the presentation of externalizing problem behavior and internalizing symptoms associated with GI problems differs between young children and older children with ASD. Therefore, behavior may have different relationships with GI symptoms at different ages, which may have implications for the treatment of and clinical approach to GI disturbances in ASD.
RESUMEN
The chronicity of sleep disturbance and its relation to co-occurring symptoms in children with autism spectrum disorder (ASD) are not well understood. The current study examined longitudinal relations among sleep and co-occurring symptoms in a large well-characterized sample of 437 children with ASD assessed at baseline and follow-up (M = 3.8 years later). Twenty-three percent experienced worsening sleep problems over time, while 31.5% showed improvement. Path analysis indicated that sleep problems at baseline predicted later development of ADHD symptoms in younger children and somatic complaints in older children. For younger children, sensory over-responsivity predicted future sleep problems. Findings suggest that sensory over-reactivity may contribute to sleep problems in some children with ASD, and that sleep problems may result in poor daytime functioning.

Background: Many individuals with autism spectrum disorder (ASD) have significant gastrointestinal (GI) symptoms, but their etiology is currently unknown. Dietary interventions are common in children and adolescents with ASD, including diets with increased omega-3 fatty acids or diets free of gluten and/or casein, which may also impact GI symptoms and nutrition. However, little is known about the relationship between nutritional intake and GI symptomatology in ASD. The objective of this study was to assess the relationships between GI symptoms, omega-3 intake, micronutrients, and macronutrients in children with ASD. Methods: A total of 120 children diagnosed with ASD participated in this multisite study. A food frequency questionnaire was completed by the patient's caretaker. The USDA Food Composition Database was utilized to provide nutritional data for the food items consumed by each participant. GI symptomatology was assessed using a validated questionnaire on pediatric gastrointestinal symptoms. Results: There were no significant associations between GI symptoms and the amount of omega-3 fatty acids and/or other micro- and macronutrients contained in the diet. Conclusions: This study suggests that dietary variations do not appear to drive GI symptoms, nor do GI symptoms drive dietary variations in those with ASD, although causation cannot be determined with this observational assessment. Furthermore, there may be other factors associated with lower GI tract symptoms in ASD, such as increased stress response.
