Predictors of work participation of young adults with mild intellectual disabilities

Individuals with intellectual disabilities (ID) are three to four times less often employed compared to their non-disabled peers. Evidence for factors associated with work participation of young adults with ID is limited. Furthermore, studies on predictors for sustainable work participation among young adults with ID is lacking altogether. Therefore, the aim of this study was to investigate which factors predict finding as well as maintaining employment of young adults with mild ID. We obtained data on 735 young adults with mild ID, aged 15–27 years, applying for a disability benefit. The follow-up period ranged from 1.25 to 2.75 years. Motivation, expectations regarding future work level and living situation predicted finding work as well as maintaining employment for at least 6 months. In this study, especially personal factors were influential in predicting work outcome and may be suitable factors to include in interventions.     

Facial emotion recognition in 4- to 8-year-olds with autism spectrum disorder: A developmental trajectory approach

The investigation of emotion recognition in autism spectrum disorder (ASD) has both theoretical and practical implications. However, although many studies have examined facial emotion recognition in ASD, some points remain unclear. We therefore studied facial emotion recognition in young children with ASD across a small age range, in order to determine (1) their ability to recognize emotion and (2) the developmental trajectory of this ability. Twenty-two children with ASD aged 4–8 years were compared with typically developing children matched on either chronological age or verbal mental age. We administered three facial emotion tasks: matching, identification, and labeling. Results showed that children with ASD and typically developing children had difficulty with labeling emotions, but not with matching or identifying them. Happiness was the easiest to recognize, and surprise the hardest. The children with ASD did not exhibit delayed onset in the development of facial emotion recognition. To conclude, emotion recognition difficulties in children with ASD primarily concern the recognition of negative emotions and the identification of surprise, as they do in TD groups. This should be taken into account in future research, as well as in the design of future intervention programs.     

Characteristics of international websites with information on developmental disabilities

The Internet often serves as a primary resource for individuals seeking health-related information, and a large and growing number of websites contain information related to developmental disabilities. This paper presents the results of an international evaluation of the characteristics and content of the top 10 ranked results (i.e., not including sponsored results – pay-per-click) returned when one of five terms related to developmental disabilities (i.e., ADHD, autism, down syndrome, learning disability, intellectual disability) was entered into one of six country specific Google online search engines (i.e., Australia (https://www.google.com.au), Canada (https://www.google.ca), Ireland (https://www.google.ie), New Zealand (https://www.google.co.nz), the United Kingdom (https://www.google.co.uk), and the United States (https://www.google.com)) on October 22, 2013. Collectively, we found that international consumers of websites related to developmental disabilities will encounter different websites with differing content and terminology, and should be critical consumers to ensure they locate the information they are seeking.     

A review of atomoxetine effects in young people with developmental disabilities

This review summarizes the pharmacokinetic characteristics, pharmacodynamic properties, common side effects, and clinical advantages and disadvantages associated with atomoxetine (ATX) treatment in typically developing children and adults with ADHD. Then the clinical research to date in developmental disabilities (DD), including autism spectrum disorders (ASD), is summarized and reviewed. Of the 11 relevant reports available, only two were placebo-controlled randomized clinical trials, and both focused on a single DD population (ASD). All trials but one indicated clinical improvement in ADHD symptoms with ATX, although it was difficult to judge the magnitude and validity of reported improvement in the absence of placebo controls. Effects of ATX on co-occurring behavioral and cognitive symptoms were much less consistent. Appetite decrease, nausea, and irritability were the most common adverse events reported among children with DD; clinicians should be aware that, as with stimulants, irritability appears to occur much more commonly in persons with DD than in typically developing individuals. Splitting the dose initially, starting below the recommended starting dose, and titrating slowly may prevent or ameliorate side effects. Patience is needed for the slow build-up of benefit.ConclusionsATX holds promise for managing ADHD symptoms in DD, but properly controlled, randomized clinical trials of atomoxetine in intellectual disability and ASD are sorely needed. Clinicians and researchers should be vigilant for the emergence of irritability with ATX treatment. Effects of ATX on cognition in DD are virtually unstudied.     

Effectiveness of a modified rapid toilet training workshop for parents of children with developmental disabilities

Individuals with developmental disabilities often experience challenges in acquiring toileting skills, which highlights a need for effective toilet training strategies that can be readily disseminated to caregivers. The purpose of this multiple baseline study was to evaluate the effectiveness of a modified rapid toilet training workshop provided to the parents of six children with developmental disabilities. In the workshop, parents were taught to implement an instructional protocol that included increased fluid intake, positive reinforcement for correct toileting, scheduled toilet sittings, scheduled chair sittings to teach initiation, neutral redirection for accidents, and procedures to enhance maintenance and generalization. Following the workshop, parents implemented the toilet training protocol at home with their children for 5-8 days, with telephone support from a researcher. Results indicate that the workshop resulted in increased in-toilet urination and defecation and decreased accidents for the five children who completed the study. The results are discussed in relation to previous and future research and implications for practice.     

School-based social skills training for young people with autism spectrum disorders

ABSTRACT

Background: The Secret Agent Society (SAS) Program, an intervention to enhance social–emotional skills, was provided by schools for children with autism spectrum disorder (ASD). The program was assessed to determine if it improved social skills at school and home, and whether improvements were maintained.

Methods: Eighty-four students participated. Key outcomes were parent and teacher ratings of emotion regulation, social skills, and direct child social problem-solving measures. The standard school curriculum served as the control condition. Phase 1 was a two-group waitlist-control comparison of SAS versus the standard curriculum. Phase 2 was a follow up of all participants before and after the intervention and at 12-months post-intervention.

Results: Parent and child measures improved after the intervention but not in the waitlist condition. Improvements in parent, child, and teacher measures were apparent at 12 months.

Conclusions: The SAS Program warrants further research as a potential program for schools that serve children with ASD.     

Cognitive, behavior and intervention outcome in young children with autism

The relations between cognition and autism severity, head size and intervention outcome, were examined. Change in cognitive level with intervention was measured in children with autism and compared to children with developmental disabilities (DD). Eighty-one children (mean age 25.9 months) with autism (n = 44) and DD (n = 37) were assessed at pre- and post 1 year of intervention. Cognitive abilities and autism severity were measured by standardized tests. Three pre-intervention cognitive level groups: normal (IQ > 90), borderline (70 < IQ < 89) and impaired (50 < IQ < 69) were examined. The impaired group had more severe autism symptoms than the borderline and the normal cognitive groups. However, following intervention the groups did not differ in the change in core autism symptoms. IQ scores increased significantly more in the autism group than in the DD group. IQ improvements correlated significantly with reduction in autism symptoms and mostly in stereotyped behaviors.Conclusions: Cognitive ability in autism is associated with autism severity. Two distinct subtypes based on cognitive level are identified. However, baseline cognitive level cannot predict the progress rate in autism symptoms with intervention. Improvement of social–communicative behaviors and the intensive intervention are related to significant cognitive increments in autism.     

Constipation prevalence and perceptions: Comparison of children and adolescents with ASD and other developmental-behavioral disorders

BackgroundFew studies have compared youth constipation in autism spectrum disorder (ASD) to constipation in other developmental-behavioral (DB) disorders.MethodsChildren and caregivers presenting to a DB pediatrics and psychology clinic completed written questionnaires on constipation. Comparison groups were ASD vs without ASD and caregiver vs child responses. Binary logistic regression were conducted to compare categorical variables.ResultsCaregivers of 169 toilet trained children and 26 non-toilet trained children completed the survey; 30 % of the toilet trained and 62 % of the non-toilet trained children had ASD. 88 toilet trained children completed the survey. Based on caregiver response, toilet trained youth with ASD were more likely to have been constipated in the past and to currently or previously taken medication to manage constipation. In both the total toilet trained and non-toilet trained sample, more caregivers endorsed their child meeting Rome IV criteria for functional constipation than endorsed current constipation. 37 % of parent/child pairs disagreed on whether the child met the Rome IV criteria. Caregivers of toilet trained youth with ASD were more likely to endorse specific barriers and impairment due to managing constipation in comparison to caregivers of youth without ASD.ConclusionsChildren with ASD may be at a higher lifetime risk of constipation and of needing medication compared to children with other DB disorders. Providers should use thorough questions to identify constipation and gather information from both caregiver and child when possible. Clinicians should consider targeting behavioral treatment recommendations to perceived caregiver concerns.     

Using the DBC-P Hyperactivity Index to screen for ADHD in young people with autism and ADHD: A pilot study

This study aimed to (1) determine preliminary validity of the Developmental Behaviour Checklist-Hyperactivity Index (DBC-HI) as a screening measure of combined-type ADHD in autism and ADHD, and (2) compare emotional-behavioural disturbance using the DBC in autism, ADHD and autism + ADHD. Forty-nine age- and PIQ-matched young people [6–18 years; 12 autism, 13 ADHD, 12 autism + ADHD, 12 typically developing] were recruited. Parents completed the Conners-Revised Rating Scale and DBC. The DBC-HI displayed strong internal consistency and good external validity, reliably measuring combined-type ADHD. The DBC-HI distinguished autism from autism + ADHD with fair sensitivity and specificity. Individuals with autism + ADHD exhibited a more severe profile of emotional-behavioural disturbance than autism or ADHD alone. The DBC may be a useful ‘all-in-one’ screening tool to (1) identify comorbidity and (2) determine the severity of emotional-behavioural disturbance in autism and/or ADHD.     

Increasing physical activity in young adults with autism spectrum disorders

Although regular physical exercise is clearly beneficial, many people with autism spectrum disorders do not exercise regularly. The present study used a multiple-baseline-across-participants design with a reversal to demonstrate that a treatment package comprising goal-setting and reinforcement substantially increased walking by young adults with autism spectrum disorders while at school. During the initial baseline condition participants were given pedometers to wear. Once each participant's number of steps stabilized, she/he sets daily goals for minimum number of steps taken and received access to valued objects or activities (reinforcers) for meeting those goals. By the end of the first treatment condition each of five participants was successfully meeting his or her goal and walking at or above 10,000 steps each day. Walking decreased when a return to baseline was implemented, then increased when treatment was reinstated. Social validity assessment indicated that both the participants and their teacher found the intervention highly acceptable. These findings suggest that simple strategies based on goal setting and reinforcement merit further investigation as interventions for increasing exercise.     

Gaze patterns during scene processing in typical adults and adults with autism spectrum disorders

BackgroundLittle is known about how adults with autism spectrum disorder (ASD) process dynamic social scenes.MethodWe studied gaze behavior in 16 adults with ASD without intellectual impairment and 16 sex- and age-matched controls during passive scene processing.ResultsAdding more characters to a scene resulted in a drop in time spent looking at faces, and an increase in time spent looking at bodies (static trials) or off-person (dynamic trials) [Scene Type × AOI × Mode: F(2, 60) = 3.54, p = .04, η²_p = .11]. Unlike controls, adults with ASD showed only a small drop in the number of fixations made [Mode × Group: F(1, 30) = 11.30, p = .002, η²_p = .27] and no increase in the duration of face fixations [Mode × AOI × Group: F(2, 60) = 3.50, p = .04, η²_p = .11] when dynamic cues were added. Thus, particularly during dynamic trials, adults with ASD spent less time looking at faces and slightly more time looking off-person than did controls [Mode × AOI × Group: F(2, 60) = 3.10 p = .05, η²_p = .09]. Exhibiting more autistic traits and being less empathic were both associated with spending less time fixating on faces [.34 < |r| < .55, p < .05].ConclusionsThese results suggest that adults with ASD may be less sensitive to, or have more difficulty processing, dynamic cues—particularly those conveyed in faces. The findings demonstrate the importance of using dynamic displays in studies involving this clinical population.     

Predictors of Developmental Outcome in 4- to 6-Year-Olds With Developmental Disability

Objective Studies on the early trajectories of developmental disability (DD) are limited. This study aimed to evaluate the diagnostic stability and developmental trajectories of autism spectrum disorder (ASD) and intellectual disability (ID), and to determine baseline clinical characteristics that affect future diagnosis. Methods We analyzed 192 children who were referred for possible DD through retrospective chart review. Clinical diagnosis was assessed once at baseline, aged 2–4, and at follow-up, aged 4–6. The participants’ developmental profiles were measured by Psychoeducational Profile-Revised (PEP-R), Vineland Social Maturity Scale (VSMS), Beery-Buktenica Developmental Test of Visual Motor Integration (VMI), and Childhood Autism Rating Scale (CARS). Results On comparing the diagnostic change, 5% of children were no longer diagnosed as ASD, and 13% of children were no longer diagnosed as ID at follow-up. Trajectories of developmental profiles were compared between children with and without ID at follow-up, and significant time-by-group interaction were observed in PEP-R (p<0.001), VSMS (p<0.001), and VMI (p=0.003) scores, indicating that children without ID at follow-up showed significant improvement over time compared to children with ID. ASD diagnosis (p<0.001) and CARS score (p=0.007) at baseline were significantly associated with ASD at follow-up, while VSMS score (p=0.004) and VMI score (p=0.019) at baseline were significantly associated with ID at follow-up. Conclusion A subset of children lost their diagnosis at follow-up, and such diagnostic change was significantly more common in ID compared to ASD. Baseline autism symptomatology was related to ASD at follow-up, and baseline adaptive and visuo-motor function was related to ID at follow-up.     

Personal factors and perceived barriers to participation in leisure activities for young and adults with developmental disabilities

Participation in leisure activities has been identified as a factor that favors inclusion in the community and it also contributes to a better quality of life. This study analyzed the influence of certain personal characteristics and environmental factors in the participation in leisure activities of youngsters and adults with developmental disabilities. A cross-sectional design was used with a convenience sample of 237 people, aged 17-65, living in the community. The participants completed the Spanish version of the Leisure Assessment Inventory, and information about the personal and disability-related factors was obtained through a questionnaire. Multiple regression analyses were conducted to determine the personal factors, disability-related factors, and perceived barriers to leisure participation. The results show that participation in leisure activities is determined more by personal factors and perceived barriers than by disability-related factors.     

A longitudinal study of schizophrenia- and affective spectrum disorders in individuals diagnosed with a developmental language disorder as children

The prevalence and types of schizophrenia- and affective spectrum disorders were studied in 469 individuals with a developmental language disorder (DLD), assessed in the same clinic during a period of 10 years, and 2,345 controls from the general population. All participants were screened through the nationwide Danish Psychiatric Central Register (DPCR). The mean length of follow-up was 34.7 years, and the mean age at follow-up 35.8 years. The results show an excess of schizophrenia spectrum disorders (F20-F29) within participants with DLD when compared with controls from the overall population (6.4% vs. 1.8%; P < 0.0001). For schizophrenia (F20.x) the respective figures were 3.8% versus 1.1%; P = 0.0001. The variable degree of expressive language disorder was significantly associated with a schizophrenia spectrum disorder diagnosis in the DPCR. There was no significant increase in affective spectrum disorders (F30-F39) in the DLD case group (3.4% vs. 2.0%; P = 0.05). Our results provide additional support to the notion that DLD is a marker of increased vulnerability to the development of schizophrenia spectrum disorders.     

A comparison of patterns of sensory processing in children with and without developmental disabilities

This study compared the patterns of sensory processing among children with autism spectrum disorder (ASD), attention deficit and hyperactivity disorder (ADHD), and children without disabilities. Parents reported on the frequency of sensory processing issues by completing the Chinese Sensory Profile (CSP). Children with disabilities (ASD or ADHD) exhibited significantly more sensory processing issues than children without disabilities. The results of GLM and discriminant analyses showed that the CSP effectively differentiated between children with and without developmental disabilities. But it failed to identify major differences in sensory processing issues between children with either ASD or ADHD. Sensory processing issues could be one of many criteria that characterize and differentiate the features of children with different developmental disabilities. Although no significant gender differences in sensory processing issues appeared, age was a significant cofounding factor in evaluating sensory processing. Children without disabilities showed some small decreases in sensory processing issues as they aged from 6 to 12 years old. Children with ASD showed some decrease in sensory processing issues over the span of their childhood, while children with ADHD showed a significant increase in auditory processing issues as well as small increases in many aspects of sensory processing.     

The progression of severe behavior disorder in young children with intellectual and developmental disabilities

Behavior disorders, such as self-injurious, stereotypic, and aggressive behavior are common among individuals with intellectual or developmental disabilities. While we have learned much about those behaviors over the past few decades, longitudinal research that looks at developmental trajectory has been rare. This study was designed to examine the trajectory of these three forms of severe behavior disorders over a one year time period. The behaviors were measured on two dimensions: frequency of occurrence and severity. Participants were 160 infants and toddlers at risk for developmental delays in Lima, Peru. Using structural equation modeling, we found that the frequency of self-injury and stereotypic behavior and the severity of aggressive behavior remained stable over the 12-month period. Uni-directional structural models fit the data best for self-injurious and aggressive behavior (with frequency being a leading indicator of future severity of self-injury and severity being a leading indicator of future frequency for aggression). For stereotypic behavior, a cross-lagged autoregressive model fit the data best, with both dimensions of frequency and severity involved as leading indicators of each other. These models did not vary significantly across diagnostic groups, suggesting that toddlers exhibiting behavior disorders may be assisted with interventions that target the specific frequencies or severities of behaviors, regardless of diagnostic category.     

A multisite trial of atomoxetine and parent training in children with autism spectrum disorders: Rationale and design challenges

Several randomized controlled trials (RCTs) involving children with autism spectrum disorder (ASD) have examined effectiveness of mono-therapies for problem behavior. However, results have not been as encouraging as in typically developing children. For example, when prescribed stimulants, children with ASD and hyperactivity/inattentiveness, show only moderately reduced symptoms, with frequent side effects. Therefore, alternative treatments or combinations of treatments are needed. The Children's Hyperactivity and Autism Research Treatment Study (CHARTS) is a randomized clinical trial comparing the individual and combined effects of atomoxetine and parent training to treat hyperactivity, inattentiveness, and noncompliance in children with ASD. Design challenges included the overall study design, targeting of different outcomes by different treatments, and data analysis. This article details options for addressing a number of these methodological issues in the context of conducting a large multicenter RCT with an ASD population.     

Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in adult psychiatry. A 20-year register study

Abstract

Nylander L, Holmqvist M, Gustafson L, Gillberg C. Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in adult psychiatry. A 20-year register study. Nord J Psychiatry 2012;Early Online:1–7 Objective: Attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) are increasingly recognized in adults. This study aimed to assess trends in diagnostic practice, diagnostic delay and comorbidity regarding ADHD and ASD in adult psychiatric patients. Methods: Individuals with diagnosed ADHD or ASD were identified in an adult psychiatry register comprising 56,462 patients. Results: ADHD was diagnosed in up to 2.7% and ASD in 1.3% of the patients. Most cases were diagnosed within 2 years of first contact with adult psychiatry, but some patients were treated for 10 years or more before being diagnosed with ADHD or ASD. Seventy per cent of ADHD and 56% of ASD patients were treated as outpatients only. Other psychiatric diagnoses were registered in about 60%. Affective disorders were common in patients with ADHD. Psychoses and intellectual disability were more common in ASD patients. Psychoactive substance use-related disorders were considerably more common in those with ADHD. Concomitant ADHD and ASD were seldom diagnosed in this clinical material. Conclusion: ADHD and ASD were probably much underdiagnosed in the studied group of psychiatric patients. Other psychiatric diagnoses were common, but not ADHD with concomitant ASD.     

Effortful control in typically developing boys and in boys with ADHD or autism spectrum disorder

Despite increased interest in the role of effortful control (EC) in developmental disorders, few studies have focused on EC in autism spectrum disorders (ASD) and no study so far has directly compared children with ASD and children with ADHD. A first aim of this study was to investigate whether typically developing (TD) boys, boys with ADHD and boys with ASD can be differentiated based on EC levels. A second aim was to evaluate the relationship between EC and symptoms of ADHD and ASD. We assessed EC in 27 TD boys, 27 boys with ADHD and 27 boys with ASD (age 10-15) using different EC questionnaires. Clinical groups scored lower than the TD group on all EC total scales, but could only be differentiated from each other by means of self-reported persistence, impulsivity and activation control. Our data suggest that although EC is useful in differentiating TD boys from clinical groups, it is less efficient in distinguishing ADHD from ASD. Also, results suggest that EC plays a role in the manifestation of symptoms of both ADHD and ASD and that high levels of EC enable children to function more adequate in daily situations.
