Multidisciplinary assessment and treatment of self-injurious behavior in autism spectrum disorder and intellectual disability: integration of psychological and biological theory and approach

Oral Health Care for Children and Youth With Developmental Disabilities: Clinical Report

Oral health is an essential component of overall health for all individuals. The oral health of children and youth with developmental disabilities (CYDD) involves unique characteristics and needs of which pediatricians and pediatric clinicians can be aware. Risk for oral disease in CYDD is multifactorial and includes underlying medical conditions, medications, and ability to participate in preventive oral health care and treatment, and lack of access to providers is common for this population despite being eligible for Medicaid. Pediatric clinicians are uniquely positioned to support the oral health needs of CYDD and their families through the medical home. This clinical report aims to inform pediatric clinicians about the unique oral health needs of CYDD. It provides guidance on assessing caries risk and periodontal status using structured screening instruments; understanding dental trauma, the role of diet and caries risk, trauma prevention, and malocclusion; and providing anticipatory guidance on oral hygiene that includes tooth brushing, use of fluoridated toothpaste, assessing community water fluoridation, advocating for a dental home by 1 year of age, and transition to adult dental care as part of adolescent health care. It also highlights special considerations for dental treatment rendered under sedation or general anesthesia that CYDD may need. Pediatric clinicians can help reduce risk of CYDD developing dental disease by understanding the unique needs of their patients and their barriers to accessing oral health care in their community, communicating with the child's dental home, and advocating for safe and accessible dental procedures.

Predictors of Aggression, Disruptive Behavior, and Anger Dysregulation in Youths with Autism Spectrum Disorder

Youth with autism spectrum disorder (ASD) often experience difficulties related to aggression, disruptive behavior, and regulation of emotions that precipitate these behaviors (i.e., anger). The extent to which aggression, disruptive behaviors, and anger dysregulation are correlated with distinct or overlapping factors has not yet been explored. The present study examined whether aspects of participant demographics, individual youth functioning, caregiver stress, and family warmth contributed to youth aggression, disruptive behavior, and anger dysregulation. Participants were caregivers of 511 youths with ASD. Analyses revealed that significant proportions of variance in aggression, disruptive behaviors, and anger dysregulation were accounted for by shared variables pertaining to demographics, the individual youth, and caregiver stress. Implications of treatment and future research are discussed.

Psychosocial interventions for suicidal and self-injurious-related behaviors among adolescents: a systematic review and meta-analysis of Chinese practices

Background

Suicidal and self-injurious-related behaviors (SSIRBs) are a serious public health challenge in China. However, a comprehensive systematic review of psychosocial interventions for SSIRBs among Chinese adolescents has not been performed. To fill this gap, this systematic review and meta-analysis aimed to examine psychosocial interventions for SSIRBs among Chinese adolescents.

Methods

Eight international (PubMed, EMBASE, Cochrane Library, ScienceDirect, Clinical Trial, CINAHL, PsycINFO, and Web of Science) and four Chinese (Wanfang, SinoMed, CEPS, and CNKI) databases were searched from inception to 31 January 2023. Data extraction and quality assessment were independently conducted by two groups of researchers. Qualitative synthesis and meta-analysis were both used.

Results

The initial search yielded 16,872 titles. Of the 649 full texts reviewed, 19 intervention articles focusing on SSIRBs met the inclusion criteria. Thirteen out of the 19 included studies involved cognitive-behavioral therapy (CBT). Seven non-suicidal self-injury (NSSI) studies assessing self-injurious behaviors were included (six short-term studies and three long-term studies). Compared with long-term interventions [-1.30 (95% CI: -1.84, -0.76)], short-term psychosocial interventions had a higher standardized mean difference (SMD) value [1.86 (95% CI: -2.72, -0.99)]. Meta-regression showed an inverse relationship between the treatment response and sample size (slope = 0.068, Z = 2.914, p = 0.004) and proportion of females (slope = 1.096, Z = 5.848, p < 0.001). Subgroup analyses showed that compared with the "less than 1 month" group [-0.494 (-0.783, -0.205)], in the "immediate postintervention" group, the pooled estimate was significantly lower [-2.800 (-4.050, -1.550), p < 0.001].

Conclusion

Our review systematically summarized the key characteristics and effectiveness of existing psychosocial interventions for SSIRBs among Chinese adolescents. Short-term psychosocial interventions for NSSI were significantly effective in reducing self-injurious behavior scores, especially in the immediate postintervention period. More favorable treatment responses could be observed in both male and small samples.

The Ethical Obligations, Barriers, and Solutions for Interprofessional Collaboration in the Treatment of Autistic Individuals

With an estimated 1 in 44 children having been diagnosed with autism and given the variety of types of service providers that treat autism, collaboration among these professionals is a necessary part of the overall treatment package for an autistic individual. However, like with any professional skill, competence in collaborating effectively must be developed, especially because behavior analysts have been criticized for being resistant to collaboration. Competence with collaboration may be developed through coursework, professional development opportunities, and supervision by someone who has demonstrated competence with collaboration. With the 2020 update to the Ethics Code for Behavior Analysts, the behavior analyst's role in collaborating with other professionals has been clarified by several expectations. Current literature also provides additional guidance on the potential barriers to collaboration as well as recommendations for how to support a collaborative team. In order to facilitate successful collaboration, it is also important to evaluate the effectiveness of the collaborative team and to take advantage of opportunities to learn about the methodologies and perspectives of the other professionals to ensure that the client's best interests are met.

The prevalence of self-harm and mental disorders among individuals with intellectual disabilities

OBJECTIVE

Mental health disorders are prevalent among individuals with intellectual disabilities (ID). However, there is a lack of research on the impact of concomitant autism spectrum disorders (ASD) or attention deficit hyperactivity disorder (ADHD) on the mental health within this population. We aimed to investigate the prevalence of mental health disorders and registered healthcare visits due to self-harm among individuals with ID.

METHOD

We used administrative data for all healthcare with at least one recorded diagnosis of mental health disorder or self-harm during 2007-2017 among people with a diagnosis of Down syndrome (DS; n = 1298) and with ID without DS (IDnonDS; n = 10,671) using the rest of the population in Stockholm Region (n = 2,048,488) for comparison.

RESULTS

The highest odds ratios for a mental health disorder were present in females with IDnonDS (9.01) followed by males with IDnonDS (8.50), compared to the general population. The ORs for self-harm among individuals with IDnonDS were high (8.00 for females and 6.60 for males). There were no registered cases of self-harm among individuals with DS. The prevalence of an anxiety or affective disorder was higher among individuals with ID including DS with concomitant ASD or ADHD. Neighbourhood socio-economic status was associated with a lower occurrence of mental health disorders and self-harm in wealthier areas for all outcomes and for all groups.

CONCLUSIONS

Self-harm and psychiatric comorbidities were common among individuals with ID without DS with an attenuated difference among those with concomitant ASD or ADHD, which calls for attention.

A review of the use of psychotropic medication to address challenging behaviour in neurodevelopmental disorders

Engagement in challenging behaviour (e.g., aggression, self-injury) is reported to occur in neurodevelopmental disorders such as intellectual disabilities (ID), autism spectrum disorder (ASD), and fragile X syndrome (FXS). Common interventions to address these behaviours include both behavioural and pharmacological approaches. Although psychotropic medications are commonly used to address challenging behaviour in ID, ASD, and FXS, demonstration of the effectiveness of treatment is limited. Furthermore, research examining interaction effects between psychotropic medication, challenging behaviour, and environmental events within specific neurodevelopmental disorders such as ID, ASD, and FXS is scarce. The purpose of this chapter is to provide an overview of challenging behaviour within ID, ASD, and FXS and of the effectiveness of psychotropic medication as an intervention for challenging behaviour within these neurodevelopmental disorders. Finally, research examining how psychotropic medication may impact the relationship between challenging behaviour and environmental events is reviewed.

Professionals' attitudes towards people with intellectual disabilities who self-harm: A literature review

BACKGROUND

National Institute for Health and Care Excellence (NICE, 2013) Guidance on Self-Harm states that professionals supporting people who self-harm should demonstrate compassion, respect and dignity. This literature review examines the evidence for professionals' attitudes towards people with intellectual disabilities who self-harm.

METHOD

Four databases (PsychInfo, IBSS, CINAHL and Medline) were systematically searched to find relevant research since 2000.

RESULTS

Four studies met the criteria. Attitudes of professionals supporting people with intellectual disabilities are contrasted with those of professionals in settings focused on supporting people without intellectual disabilities. Professionals supporting people with intellectual disabilities tended to display attitudes and attributions reflective of biobehavioural and psychosocial theories of self-harm, with a greater emphasis on relationships.

CONCLUSION

Much more research is needed which examines the attitudes of professionals supporting people with intellectual disabilities who self-harm.

Self-reported explanations for self-injury by people with intellectual disabilities: a systematic review of qualitative studies

Background

Emotional distress has received less attention as an explanatory factor for self-injury in people with intellectual disabilities, with research and practice primarily focusing on biobehavioural factors. This systematic review examines the self-reported explanations for self-injury by people with mild or moderate intellectual disabilities, and discusses how the findings contrast with those from self-reported studies of people within the general population who self-harm.

Methods

Five databases (PsychINFO, IBSS, CINAHL, Web of Science and Medline) were systematically searched to find qualitative, empirical research since 2000 about self-reported reasons for self-injury.

Results

Four studies were found which conducted research with people with intellectual disabilities. Three primary themes are discussed: relief from overwhelming emotions; trauma and loss; and difficulty in articulating emotions.

Conclusion

This review found a paucity of research asking people with intellectual disabilities about their own self-injury. However, the research available suggests that explanatory factors for self-injury typically reported in the general population should be considered for those with mild or moderate intellectual disabilities.

Brief Report: Suspected Cannabis-Induced Mania and Psychosis in Young Adult Males with Autism Spectrum Disorder

There is increasing interest in investigating cannabis for behavioral symptoms in individuals with autism spectrum disorder (ASD). The potential role of dysregulated cannabinoid signaling contributing to the pathophysiology of ASD is an area of active investigation. Results from retrospective and uncontrolled trials of cannabis in subjects with ASD have been published, reporting both potential benefits and adverse effects. Here, we describe the clinical course of three young adult males with ASD who developed mania or psychosis after the consistent use of cannabidiol and delta-9-tetrahydrocannabinol. Caution should be utilized with cannabis use in individuals with ASD until large-scale, replicated randomized controlled trials demonstrating efficacy, safety and tolerability have been published.

Understanding the experiences of self-injurious behavior in autism spectrum disorder: Implications for monitoring technology design

OBJECTIVE

Monitoring technology may assist in managing self-injurious behavior (SIB), a pervasive concern in autism spectrum disorder (ASD). Affiliated stakeholder perspectives should be considered to design effective and accepted SIB monitoring methods. We examined caregiver experiences to generate design guidance for SIB monitoring technology.

MATERIALS AND METHODS

Twenty-three educators and 16 parents of individuals with ASD and SIB completed interviews or focus groups to discuss needs related to monitoring SIB and associated technology use.

RESULTS

Qualitative content analysis of participant responses revealed 7 main themes associated with SIB and technology: triggers, emotional responses, SIB characteristics, management approaches, caregiver impact, child/student impact, and sensory/technology preferences.

DISCUSSION

The derived themes indicated areas of emphasis for design at the intersection of monitoring and SIB. Systems design at this intersection should consider the range of manifestations of and management approaches for SIB. It should also attend to interactions among children with SIB, their caregivers, and the technology. Design should prioritize the transferability of physical technology and behavioral data as well as the safety, durability, and sensory implications of technology.

CONCLUSIONS

The collected stakeholder perspectives provide preliminary groundwork for an SIB monitoring system responsive to needs as articulated by caregivers. Technology design based on this groundwork should follow an iterative process that meaningfully engages caregivers and individuals with SIB in naturalistic settings.

Rationale, Development, and Description of a Brief Family-Centered Service Provision Model for Addressing Children's Severe Behavior

For families with children with autism that engage in severe behavior, the American Academy of Pediatrics recommends that functional assessment and management of environmental variables contributing to severe behavior occur prior to the prescription of psychopharmacologic treatment. Despite the inclusion of this recommendation in guidance articles published in pediatric journals for more than a decade, access to such services may not be feasible, in particular for families living in rural and geographically isolated communities. Given that families often view pediatricians as their first line of professional guidance for addressing challenges surrounding child development, the inaccessibility of appropriate services for managing healthcare is a concern for many pediatricians. To address this issue, a brief family-centered service provision model was developed through a collaboration between healthcare providers at a university-based hospital and Applied Behavior Analysis program faculty of the affiliated university. The hospital served many families living in rural areas of the state; therefore, the model utilized research-based practices with evidence of ecological validity for providing function-based assessment and treatment services. Within this manuscript we present a description of the model and its current implementation at a university-based hospital. For a data-based evaluation of the clinic and model, we refer readers to https://osf.io/qx8ak.

Brief Report: Associations Between Self-injurious Behaviors and Abdominal Pain Among Individuals with ASD-Associated Disruptive Mutations

Self-injurious behaviors (SIB) are elevated in autism spectrum disorder (ASD) and related genetic disorders, but the genetic and biological mechanisms that contribute to SIB in ASD are poorly understood. This study examined rates and predictors of SIB in 112 individuals with disruptive mutations to ASD-risk genes. Current SIB were reported in 30% of participants and associated with poorer cognitive and adaptive skills. History of severe abdominal pain predicted higher rates of SIB and SIB severity after controlling for age and adaptive behavior; individuals with a history of severe abdominal pain were eight times more likely to exhibit SIB than those with no history. Future research is needed to examine associations between genetic risk, pain, and SIB in this population.

Associated Factors of Self-injury Among Adolescents with Autism Spectrum Disorder in a Community and Residential Treatment Setting

Self-injurious behavior (SIB) occurs in up to 50% of individuals with autism. As one of the most serious conditions in individuals with developmental disabilities, SIB affects the individual and his or her family in multiple contexts. A systematic analysis of factors most commonly associated with SIB could inform the development of individualized intervention strategies. The current study examined factors related to SIB in an analysis of client records of 145 children with autism in a comprehensive care center. Predictor variables included age, gender, the Adaptive Behavior Composite, sensory processing, aggression, stereotypies, irritability, adaptive skills, and medical conditions. Age, irritability, and the Adaptive Behavior Composite were found to significantly predict SIB.

Toward Actionable Practice Parameters for "Dual Diagnosis": Principles of Assessment and Management for Co-Occurring Psychiatric and Intellectual/Developmental Disability

PURPOSE OF REVIEW

Although treatment algorithms and parameters for best practice are readily available for all major syndromes of psychiatric impairment, the occurrence of psychiatric syndromes in individuals with intellectual and developmental disability (IDD) invokes serious contextual challenges for interpretation of symptoms, diagnosis, and optimization of treatment, both for clinicians and for the service sectors in which care and support of individuals with IDD are delivered. Recognizing that there exist very few definitive resources for best practice under the circumstance of this form of "dual diagnosis," the Missouri Department of Mental Health convened an expert panel to conduct a focused review and synthesis of the relevant scientific literature from which to develop guidance in the form of decision support to clinicians. This article summarizes the findings for three of the most common and impairing clusters of psychiatric symptoms that co-occur with IDD-aggression, depression, and addictions.

RECENT FINDINGS

Individuals with IDD are at high risk for the development of psychiatric symptoms (PS), which often manifest uniquely in IDD and for which evidence for effective intervention is steadily accruing. Interventions that are commonly implemented in the IDD service sector (e.g., functional communication training and positive behavioral support planning) are capable of mitigating severe behavioral impairment, yet rarely invoked when dual diagnosis patients are seen in the psychiatric service sector. Conversely, state-of-the-art interventions for traumatic stress, pharmacotherapy, and psychotherapy have proven capable of improving behavioral impairments in IDD but are typically restricted to the psychiatric service sector, where there exist significant barriers to access for patients with IDD, including limitations imposed by diagnostic eligibility and practitioner experience. Bridging these gaps in knowledge and clinical capacity across the respective IDD and PS service sectors should be of very high priority in strategizing the care and support of IDD patients with serious co-occurring psychiatric conditions.

Evaluating the Relationship between the Rate and Temporal Distribution of Self-Injurious Behavior

Self-injurious behavior (SIB) presents unique challenges as researchers have identified that some SIB may be resistant to treatment. The unit of analysis in this research is often the frequency of behavior with relatively little attention devoted to the analysis of inter-response time relations. We assessed whether changes in the rate of SIB were also associated with changes in the temporal distribution of this behavior in the presence and absence of systematically manipulated environmental variables. This study included three participants diagnosed with profound intellectual disabilities who engaged in SIB maintained by both negative and automatic reinforcement. For two of the participants, we used a multiple baseline design across participants to assess the effects of noncontingent access to preferred activities on both the rate and temporal distribution of SIB. For the third participant, we used a reversal design to assess the effects of a change in daily schedule (i.e., attending or not attending work) on the rate and temporal distribution of SIB. For all three participants, antecedent manipulations decreased the rate of SIB; however, operant contingency values (a measure of temporal distribution) did not change in a corresponding fashion. These data suggest that although antecedent manipulations may decrease the overall rate of the behavior, once SIB is emitted, additional instances are likely to occur close together in time.

Retinal burns from laser pointers: a risk in children with behavioural problems

OBJECTIVE

To explore self-inflicted retinal burns from laser pointers in children.

METHODS

Literature review of laser pointer retinal injuries in childhood and online survey of UK Consultant Ophthalmologists. A cohort of local children with self-inflicted injury is described. The matter is topical. We review progress in recent legislation and policy change in the UK.

RESULTS

Four of 77 case reports of laser burns in childhood analysed reported psychological or behavioural issues. Three of four children in our cohort had such issues. Delay in diagnosis occurred in two of our patients. Structural retinal damage persisted for over 12 months in all four children (seven eyes). Our survey of UK ophthalmologists found 159 cases of injury (85% male), 80% under 20 years of age. The majority of the laser pointers were purchased online. Many patients (36%) suffered moderate vision loss (6/18 to 6/60 Snellen), while 17% (at least 11 patients) suffered severe vision loss (<6/60 Snellen).

CONCLUSION

We highlight the risk of macular damage and vision loss from handheld lasers specifically in children with behavioural, learning or mental health issues. The diagnosis may be difficult or delayed in such children. In children with uncertain macular changes, ophthalmologists should explore the history for possible instances of exposure to handheld lasers pointers. Regulatory authorities and manufacturers of handheld lasers need to be aware of the risk to children. Furthermore, there is a need to better inform parents, carers and teachers of the risk of ocular self-injury from such lasers pointers.

Personal characteristics and outcomes of individuals with developmental disabilities who need support for self-injurious behaviour

BACKGROUND

For people with intellectual and developmental disabilities, self-injurious behaviour (SIB) can have serious negative effects on both health and quality of life. This descriptive analysis will provide information on the characteristics and outcomes of a subsample of individuals who are identified as needing some or extensive support for SIB in the National Core Indicators Adult Consumer Survey sample.

METHODS

The data for this analysis come from states that participated in the 2015-2016 data collection cycle of National Core Indicators Adult Consumer Survey which is a face-to-face survey of adults receiving services through state developmental disability agencies.

RESULTS

The characteristics and outcomes of individuals who need at least some support for SIB differ from those of individuals with intellectual and developmental disabilities who do not need support for SIB. Individuals with SIB support needs, for example, tend to live in more structured settings, have fewer relationships, less inclusion in their communities and poorer employment outcomes.

CONCLUSIONS

The exploratory descriptive analysis concludes with suggested recommendations for more standardised definitions of SIB in public systems, enhanced behaviour plan protocols and the need for additional research.

Frequency of pediatric traumatic cataract and simultaneous retinal detachment

PURPOSE

Traumatic cataract in children is a treatable cause of vision loss. In cases of simultaneous retinal detachment, the prognosis for visual recovery is often poor. The purpose of this study was to investigate risk factors for concurrent retinal detachment in patients with traumatic cataract.

METHODS

A retrospective review of patients diagnosed with traumatic cataract at Children's Hospital Colorado between 2005 and 2014 was conducted. Demographics, mechanism of injury, and incidence of retinal detachment were recorded. Logistic modeling with generalized estimating equations to account for correlation of eyes within patients was used to analyze associations between potential risk factors and retinal detachment.

RESULTS

A total of 62 total eyes with traumatic cataract were included: 52 patients presented with unilateral cataract; 5 presented with bilateral cataracts. Mean patient age was 8.4 ± 4.1 years (range, 0-16 years), and 83% of patients were male. A total of 9 eyes (14.5%) had comorbid retinal detachment. Traumatic cataracts caused by self-injurious hitting were more likely to present with simultaneous retinal detachment than those caused by other mechanisms of injury (OR = 24.0; 95% CI, 3.8-153.3; P = 0.0010).

CONCLUSIONS

Patients with traumatic cataract who display self-injurious behavior are at higher risk for concurrent retinal detachment. These patients can often only be examined under sedation. Ophthalmologists should counsel families of high-risk patients and consider involving retinal specialists in surgical planning.

Self-injurious behaviors in children with autism spectrum disorder enrolled in the Study to Explore Early Development

We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical instruments, and birth certificates. We employed a log-binomial regression to assess these associations. Although most associations were quite similar for currently and ever exhibiting self-injurious behaviors, a few differences were noted. We documented previously unreported associations of current self-injurious behaviors with maternal age and cesarean delivery, and ever self-injurious behaviors with maternal age, child sex, gestational age, and maternal race. We also confirmed previously reported associations with adaptive skills, somatic conditions (sleep, gastrointestinal, and sensory abnormalities), and other behavioral problems. These findings are informative for clinical practice and future research.

Brief Report: Self-Injurious Behaviors in Preschool Children with Autism Spectrum Disorder Compared to Other Developmental Delays and Disorders

We compared the prevalence of self-injurious behaviors (SIB) in preschoolers aged 30-68 months with autism spectrum disorder (ASD) (n = 691) versus other developmental delays and disorders (DD) (n = 977) accounting for sociodemographic, cognitive, and medical factors. SIB prevalence was higher in ASD versus all DD [adjusted odds-ratio (aOR) 2.13 (95% confidence interval (95% CI) 1.53, 2.97)]. In subgroup analyses, SIB prevalence was higher in ASD versus DD without ASD symptoms [aOR 4.42 (95% CI 2.66, 7.33)], but was similar between ASD and DD with ASD symptoms [aOR 1.09 (95% CI 0.68, 1.77)]. We confirmed higher prevalence of SIB in ASD versus DD, independent of confounders. In children with DD, SIB prevalence increased with more ASD symptoms. These findings are informative to clinicians, researchers, and policymakers.

Recognizing the Problem of Suicidality in Autism Spectrum Disorder

Until recently, suicidality in autism spectrum disorder (ASD) was rarely discussed. A cluster of recent articles, including an article by Culpin et al.¹ in this issue, has highlighted not only that suicidal thoughts and suicide attempts can occur in adolescents and young adults with ASD, but also that suicidality is likely more common in ASD than in the general population. Retrospectively, the lack of focus on suicidality in ASD seems surprising when self-injurious behavior has long been a focus of attention in ASD.² The emerging studies indicate that the increased risk of self-injurious behavior in younger and less cognitively able children with ASD^3,4 is matched by an increased risk of suicidality in those at a more advanced developmental level.

Self-Injurious Behavior in Children With Developmental Disabilities: A Systematic Review of Behavioral Intervention Literature

We reviewed single-case research studies examining the effects of behavioral interventions for self-injurious behavior (SIB) in young children with autism and developmental disabilities. Systematic searches of electronic databases, journals, and reference lists identified 46 studies (66 participants younger than the age of 12) meeting inclusion criteria. Studies were examined based on (a) participant demographics, (b) topography and function of SIB, (c) type of functional behavior assessment (FBA), (d) intervention procedures and outcomes, and (e) experimental design and measurement. Intervention strategies were categorized as antecedent manipulations, teaching behavior, consequence-based procedures, and/or extinction procedures. Positive outcomes were reported for 78% of participants in the reviewed studies and 88% of the participants were diagnosed with autism. Results suggest the effectiveness of behavioral interventions to decrease SIB for young children with disabilities; however, the frequent use of packaged interventions without component analysis limits the conclusiveness of any treatment recommendation. Suggestions for future research are discussed.

Self-Injury in Autism Spectrum Disorder and Intellectual Disability: Exploring the Role of Reactivity to Pain and Sensory Input

This paper provides information about the prevalence and topography of self-injurious behavior in children and adults with autism spectrum disorder and intellectual disability. Dominant models regarding the etiology of self-injury in this population are reviewed, with a focus on the role of reactivity to pain and sensory input. Neuroimaging studies are presented and suggestions are offered for future research.

Brief Report: Prevalence of Self-injurious Behaviors among Children with Autism Spectrum Disorder-A Population-Based Study

Self-injurious behaviors (SIB) have been reported in more than 30 % of children with an autism spectrum disorder (ASD) in clinic-based studies. This study estimated the prevalence of SIB in a large population-based sample of children with ASD in the United States. A total of 8065 children who met the surveillance case definition for ASD in the Autism and Developmental Disabilities Monitoring (ADDM) Network during the 2000, 2006, and 2008 surveillance years were included. The presence of SIB was reported from available health and/or educational records by an expert clinician in ADDM Network. SIB prevalence averaged 27.7 % across all sites and surveillance years, with some variation between sites. Clinicians should inquire about SIB during assessments of children with ASD.

Factors Associated with Self-Injurious Behaviors in Children with Autism Spectrum Disorder: Findings from Two Large National Samples

In this study, we explored potential associations among self-injurious behaviors (SIB) and a diverse group of protective and risk factors in children with autism spectrum disorder from two databases: Autism and Developmental Disabilities Monitoring (ADDM) Network and the Autism Speaks-Autism Treatment Network (AS-ATN). The presence of SIB was determined from children's records in ADDM and a parent questionnaire in AS-ATN. We used multiple imputation to account for missing data and a non-linear mixed model with site as a random effect to test for associations. Despite differences between the two databases, similar associations were found; SIB were associated with developmental, behavioral, and somatic factors. Implications of these findings are discussed in relation to possible etiology, future longitudinal studies, and clinical practice.

Predictors of emergency department use by adolescents and adults with autism spectrum disorder: a prospective cohort study

OBJECTIVES

To determine predictors of emergency department (ED) visits in a cohort of adolescents and adults with autism spectrum disorder (ASD).

DESIGN

Prospective cohort study.

SETTING

Community-based study from Ontario, Canada.

PARTICIPANTS

Parents reported on their adult sons and daughters with ASD living in the community (n=284).

MAIN OUTCOME MEASURES

ED visits for any reason, ED visits for medical reasons and ED visits for psychiatric reasons over 1 year.

RESULTS

Among individuals with ASD, those with ED visits for any reason were reported to have greater family distress at baseline (p<0.01), a history of visiting the ED during the year prior (p<0.01) and experienced two or more negative life events at baseline (p<0.05) as compared with those who did not visit the ED. Unique predictors of medical versus psychiatric ED visits emerged. Low neighbourhood income (p<0.01) and living in a rural neighbourhood (p<0.05) were associated with medical but not psychiatric ED visits, whereas a history of aggression (p<0.05) as well as being from an immigrant family (p<0.05) predicted psychiatric but not medical emergencies.

CONCLUSIONS

A combination of individual and contextual variables may be important for targeting preventative community-based supports for individuals with ASD and their families. In particular, attention should be paid to how caregiver supports, integrative crisis planning and community-based services may assist in preventing or minimising ED use for this vulnerable population.

Brief Report: Further Examination of Self-Injurious Behaviors in Children and Adolescents with Autism Spectrum Disorders

Self-injurious behaviors (SIB) are problematic for many children with autism spectrum disorders (ASD). Existing models to explain factors contributing to SIB fail to account for a large proportion of variance in SIB. This study attempted to explain a greater proportion of variance in SIB by addressing methodological/theoretical limitations in previous research using a sample of 2341 youth with ASD. The model comprised of predictors identified by the prior study continued to explain only a small proportion of variance in the SIB score (R (2) = .13). Revisions to the model failed to substantially improve model fit. Results suggest that psychological, cognitive, and behavioral factors alone do not adequately explain common measures of SIB and highlight the need for further research.

Cataract secondary to self-inflicted blunt trauma in children with autism spectrum disorder

We report 3 cases of bilateral cataract secondary to self-inflicted blunt eye trauma in children with autism spectrum disorder (ASD). All 3 children hit their foreheads, orbits, or globes repeatedly for long periods of time and developed cataracts. Clinicians must be aware of this phenomenon to diagnose ocular pathology early and to provide adequate education, counseling, and services to affected patients and their families and to put appropriate postoperative care mechanisms in place to prevent permanent ocular damage.

Irritability and Problem Behavior in Autism Spectrum Disorder: A Practice Pathway for Pediatric Primary Care

OBJECTIVE

Pediatric primary care providers (PCPs) caring for patients with autism spectrum disorder (ASD) often encounter irritability (vocal or motoric outbursts expressive of anger, frustration, or distress) and problem behavior (directed acts of aggression toward other people, self, or property). The Autism Intervention Research Network on Physical Health and Autism Speaks Autism Treatment Network charged a multidisciplinary workgroup with developing a practice pathway to assist PCPs in the evaluation and treatment of irritability and problem behavior (I/PB).

METHODS

The workgroup reviewed the literature on the evaluation and treatment of contributory factors for I/PB in ASD. The workgroup then achieved consensus on the content and sequence of each step in the pathway.

RESULTS

The practice pathway is designed to help the PCP generate individualized treatment plans based on contributing factors identified in each patient. These factors may include medical conditions, which the PCP is in a key position to address; functional communication challenges that can be addressed at school or at home; psychosocial stressors that may be ameliorated; inadvertent reinforcement of I/PB; and co-occurring psychiatric conditions that can be treated. The pathway provides guidance on psychotropic medication use, when indicated, within an individualized treatment plan. In addition to guidance on assessment, referral, and initial treatment, the pathway includes monitoring of treatment response and periodic reassessment.

CONCLUSIONS

The pediatric PCP caring for the patient with ASD is in a unique position to help generate an individualized treatment plan that targets factors contributing to I/PB and to implement this plan in collaboration with parents, schools, and other providers.

Pain in Intellectually Disabled Children: Towards Evidence-Based Pharmacotherapy?

This critical opinion article deals with the challenges of finding the most effective pharmacotherapeutic options for the management of pain in intellectually disabled children and provides recommendations for clinical practice and research. Intellectual disability can be caused by a wide variety of underlying diseases and may be associated with congenital anomalies such as cardiac defects, small-bowel obstructions or limb abnormalities as well as with comorbidities such as scoliosis, gastro-esophageal reflux disease, spasticity, and epilepsy. These conditions themselves or any necessary surgical interventions are sources of pain. Epilepsy often requires chronic pharmacological treatment with antiepileptic drugs. These antiepileptic drugs can potentially cause drug-drug interactions with analgesic drugs. It is unfortunate that children with intellectual disabilities often cannot communicate pain to caregivers. Although these children are at high risk of experiencing pain, researchers nevertheless often have to exclude them from trials on pain management because of ethical considerations. We therefore make a plea for prescribers, researchers, patient organizations, pharmaceutical companies, and policy makers to study evidence-based, safe and effective pharmacotherapy in these children through properly designed studies. In the meantime, parents and clinicians must resort to validated pain assessment tools such as the revised FLACC scale.

Autism as a disorder of biological and behavioral rhythms: toward new therapeutic perspectives

There is a growing interest in the role of biological and behavioral rhythms in typical and atypical development. Recent studies in cognitive and developmental psychology have highlighted the importance of rhythmicity and synchrony of motor, emotional, and interpersonal rhythms in early development of social communication. The synchronization of rhythms allows tuning and adaptation to the external environment. The role of melatonin in the ontogenetic establishment of circadian rhythms and the synchronization of the circadian clocks network suggests that this hormone might be also involved in the synchrony of motor, emotional, and interpersonal rhythms. Autism provides a challenging model of physiological and behavioral rhythm disturbances and their possible effects on the development of social communication impairments and repetitive behaviors and interests. This article situates autism as a disorder of biological and behavioral rhythms and reviews the recent literature on the role of rhythmicity and synchrony of rhythms in child development. Finally, the hypothesis is developed that an integrated approach focusing on biological, motor, emotional, and interpersonal rhythms may open interesting therapeutic perspectives for children with autism. More specifically, promising avenues are discussed for potential therapeutic benefits in autism spectrum disorder of melatonin combined with developmental behavioral interventions that emphasize synchrony, such as the Early Start Denver Model.
