Treatment for Higher-Order Restricted Repetitive Behaviors (H-RRB) in Children with Autism Spectrum Disorder

A systematic review of emotion regulation in parent-mediated interventions for autism spectrum disorder

Autistic individuals are at elevated risk for difficulties with emotion regulation (ER) that emerge early in life and are associated with a range of internalizing and externalizing disorders. Existing interventions that support ER have focused on school-age autistic children and adolescents as well as adults. Proactive approaches to improving ER in early childhood are thus needed, as is understanding the approaches by which ER skills can be feasibly supported in this young population. This review summarizes how ER has been measured within parent-mediated interventions for children at or under the age of 6 years and the extent to which ER is measured concurrently with or distinctly from observable behaviors that have been referenced in existing literature as externalizing or challenging behavior. Using PsycInfo, EBSCOhost, and PubMed databases, we searched for peer-reviewed journal articles published through August 2021, that focused on the use of parent-mediated interventions targeting ER and/or challenging behavior. The systematic search resulted in 4,738 publications; following multi-stage screening, the search yielded 20 studies. Eighteen of 20 studies were designed to target challenging behavior using manualized curricula or behavior analytic methodologies and assessed child outcomes through validated caregiver rating scales and/or direct behavioral observation. One study measured changes in ER as secondary to the social communication skills that were targeted in the intervention. Only one study specifically supported ER skill development and measured changes in ER as the primary intervention outcome. Findings highlight the need for better assessment of ER outcomes within the context of parent-mediated interventions for toddlers and young autistic children.

Association Between Sensory Features and High-Order Repetitive and Restricted Behaviors and Interests Among Children With Autism Spectrum Disorder

IMPORTANCE

Children diagnosed with autism spectrum disorder (ASD) are often referred to occupational therapy practitioners so their sensory features and their repetitive and restricted behaviors and interests (RRBIs) can be addressed. RRBIs include an insistence on sameness, narrow interests, rigid routines, and rituals. However, there is a paucity of knowledge concerning the association between sensory features-across patterns, modalities, and contexts-and high-order RRBIs among children with ASD who are cognitively able.

OBJECTIVE

To examine the association between sensory features across sensory patterns, modalities, and contexts and high-order RRBIs in children with ASD.

DESIGN

Correlational clinical study based on parent questionnaire responses.

SETTING

General education system in Israel.

PARTICIPANTS

Parents of 39 cognitively able school-age children with ASD (ages 6-10 yr; 34 boys and 5 girls), recruited by means of convenience sampling.

OUTCOMES

High-order RRBIs were assessed with relevant subscales from the Repetitive Behavior Scale-Revised (RBS-R), and sensory features across patterns, modalities, and contexts were examined with the Sensory Experiences Questionnaire, Version 2.1. The study hypotheses were formulated before data were collected.

RESULTS

Significant correlations were observed between the high-order RRBIs of children with ASD and their sensory features across patterns, sensory modalities, and contexts. Fifty-one percent of the total RBS-R scores were predicted by sensory hyperresponsiveness, and an additional 11% were predicted by sensory-seeking behaviors.

CONCLUSIONS AND RELEVANCE

The hypotheses concerning the association between sensory features and high-order RRBIs were confirmed. The findings enhance occupational therapy practitioners' understanding of this association and may assist in the planning of more efficient interventions. What This Article Adds: The findings enhance clinical knowledge concerning the association between sensory features and high-order RRBIs and may lay a better foundation for occupational therapy interventions for children with ASD and their families.

Repetitive Restricted Behaviors in Autism Spectrum Disorder: From Mechanism to Development of Therapeutics

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by deficits in social communication, social interaction, and repetitive restricted behaviors (RRBs). It is usually detected in early childhood. RRBs are behavioral patterns characterized by repetition, inflexibility, invariance, inappropriateness, and frequent lack of obvious function or specific purpose. To date, the classification of RRBs is contentious. Understanding the potential mechanisms of RRBs in children with ASD, such as neural connectivity disorders and abnormal immune functions, will contribute to finding new therapeutic targets. Although behavioral intervention remains the most effective and safe strategy for RRBs treatment, some promising drugs and new treatment options (e.g., supplementary and cell therapy) have shown positive effects on RRBs in recent studies. In this review, we summarize the latest advances of RRBs from mechanistic to therapeutic approaches and propose potential future directions in research on RRBs.

Patterns of Special Education Eligibility and Age of First Autism Spectrum Disorder (ASD) Identification Among US Children with ASD

The study examined timing of autism spectrum disorder (ASD) identification in education versus health settings for 8-year-old children with ASD identified through records-based surveillance. The study also examined type of ASD symptoms noted within special education evaluations. Results indicated that children with records from only education sources had a median time to identification of ASD over a year later than children with records from health sources. Black children were more likely than White children to have records from only education sources. Restricted and repetitive behaviors were less frequently documented in educational evaluations resulting in developmental delay eligibility compared to specific ASD eligibility among children with ASD. Future research could explore strategies reduce age of identification in educational settings and increase equitable access to health evaluations.

Brief Report: Replication of the Five-Factor Structure of the Autism Impact Measure (AIM) in an Independent Sample

The Autism Impact Measure is a caregiver-reported, behaviorally based measure designed to assess both frequency and functional impact of core ASD symptoms in children. This study used confirmatory factor analysis to determine if the factor structure of the AIM (Repetitive Behavior, Communication, Atypical Behavior, Social Reciprocity, and Peer Interaction), previously reported by Mazurek et al. (Journal of Autism and Developmental Disorders 50: 2307-2319, 2020), was supported in a large (n = 611), independent sample. The sample was diverse in age (2-16 years) and IQ (M = 76.6, SD = 22.7), but was composed of approximately 80% males. There were some nuanced differences between this study and Mazurek et al. (Journal of Autism and Developmental Disorders 50: 2307-2319, 2020), but findings generally provided further evidence supporting the psychometric properties of the AIM.

Examination of the Effectiveness and Acceptability of a Play-Based Sibling Intervention for Children with Autism: A Single-Case Research Design

Complementary and reciprocal interactions are a defining feature of sibling relationships for young children. However, the social and communication difficulties of children with autism spectrum disorder (ASD) can make reciprocal play more difficult and play between siblings can be less rewarding. Sibling play can serve an important role in intervention and family cohesiveness, but there is no consistent method for involving siblings in intervention benefitting the sibling dyad. This study evaluated a novel treatment package including training siblings on play strategies to increase positive sibling play in combination with a sibling support group to offer social support for the neurotypical sibling (NT). The effects of the treatment package on NT sibling play and fidelity of implementation of naturalistic play strategies was examined using a concurrent multiple-baseline design across six dyads, five of whom completed the intervention. After behavior skills training, all NT siblings increased the number of strategies they used, and increased the frequency of initiations towards their sibling with ASD. In addition, the percentage of reciprocal play between siblings increased. Generalization probes and follow-up probes demonstrated above-baseline levels of performance across most dyads, indicating that the skills learned generalized across other toys and were maintained over time. Only three of the sibling support group sessions were completed due to the COVID-19 pandemic. Although the effectiveness of the sibling support group cannot be determined, social validity questionnaires suggest siblings and parents valued and liked the support group.

Behavioral Affect in Children with Autism Spectrum Disorder during School Closures Due to the COVID-19 Pandemic in Japan: A Case-Controlled Study

Children with autism spectrum disorder (ASD) could experience more stress due to the changes consequent to school closures because of the coronavirus disease 2019 (COVID-19) pandemic. This study investigated differences in behavioral affect between children with ASD and typically developing children (TD). We conducted an online survey with mothers. The data of 84 children with ASD and 361 TD children aged 6 to 18 years were analyzed. Children with ASD were more frustrated due to the changes in their schedule and engaged more in restricted and repetitive behavior. Children with ASD had different types of behavioral affect compared to TD.

TrASDition Training: An online parental training for transition-age youth with autism spectrum disorder

Transition to the adult age represents a rather challenging period of life for youth with Autism Spectrum Disorder (ASD) and for their families. Given the actual lack of integrated healthcare systems for autistic young-adults, enhancing parental skills could represent a feasible program to improve skills preparatory for transition in adult life. The online approach, providing easy access to services which otherwise would burden a daily family organization, already strenuous for a family with an autistic person, can represent an innovative way of delivering intervention. Therefore, we developed an online psychoeducational parental training, named TrASDition Training, with a 6 months duration, addressed to parents of autistic youth with and without Intellectual Disability during the transition age. The aim of this study was to longitudinally evaluate the impact of the online parental training on the adaptive functioning, on the repetitive and problematic behaviors of ASD youth (n = 23) and on parental stress. After 6 months of Training, we found a significant improvement in adaptive functioning of ASD participants and a reduction of parental stress.

Joseph S. Coaching via Telehealth: Caregiver-Mediated Interventions for Young Children on the Waitlist for an Autism Diagnosis Using Single-Case Design

Years can elapse between parental suspicion of a developmental delay and a diagnostic assessment, ultimately delaying access to medically necessary, autism-specific intervention. Using a single-case, concurrent multiple baseline design, autism spectrum disorder symptomology (i.e., higher-order restrictive and repetitive behaviors and interests; higher-order RRBIs) was targeted in toddlers (21-35 months) waiting for a diagnostic appointment. Caregivers were coached via telehealth to mediate early intervention to decrease interfering, inflexible higher-order RRBIs during play using four evidence-based applied behavior analytic strategies: modeling, prompting, differential reinforcement of appropriate behaviors, and response interruption and redirection. Six mother-child dyads were recruited from pediatrician offices and early intervention service districts in the United States. All families were considered under-served, under-resourced, or living in rural locations. A visual analysis of the data combined with Tau-U revealed a strong basic effect between the intervention package and parent strategy use and child flexible and inflexible behavior. Findings were consistent across participants with one exception demonstrating a moderate effect for flexible behaviors yet a strong effect for inflexible behaviors. Standardized mean difference was beyond zero for all participants. Implications for science and practice include support for early intervention of higher-order RRBIs for young children with and at risk for ASD.

The Impact of COVID-19 on the Adaptive Functioning, Behavioral Problems, and Repetitive Behaviors of Italian Children with Autism Spectrum Disorder: An Observational Study

Children with autism spectrum disorder (ASD) and their families have represented a fragile population on which the extreme circumstances of the COVID-19 outbreak may have doubly impaired. Interruption of therapeutical interventions delivered in-person and routine disruption constituted some of the main challenges they had to face. This study investigated the impact of the COVID-19 lockdown on adaptive functioning, behavioral problems, and repetitive behaviors of children with ASD. In a sample of 85 Italian ASD children (mean age 7 years old; 68 males, 17 females), through a comparison with a baseline evaluation performed during the months preceding COVID-19, we evaluated whether after the compulsory home confinement any improvement or worsening was reported by parents of ASD individuals using standardized instruments (Adaptive Behavior Assessment System (Second Edition), Achenbach Child Behavior Checklist, Repetitive Behavior Scale-Revised). No significant worsening in the adaptive functioning, problematic, and repetitive behaviors emerged after the compulsory home confinement. Within the schooler children, clinical stability was found in reference to both adaptive skills and behavioral aspects, whereas within preschoolers, a significant improvement in adaptive skills emerged and was related to the subsistence of web-delivered intervention, parental work continuance, and online support during the lockdown.

Psychological treatment strategies for challenging behaviours in neurodevelopmental disorders: what lies beyond a purely behavioural approach?

PURPOSE OF REVIEW

Challenging behaviour shown by individuals with neurodevelopmental disorders (NDDs) has a major negative impact. There is robust evidence for the efficacy of treatments based on applied behaviour analysis. However, such approaches are limited in important ways - providing only part of the whole solution. We reviewed the literature to provide an overview of recent progress in psychological treatments for challenging behaviour and how these advance the field beyond a purely behavioural approach.

RECENT FINDING

We identified 1029 articles via a systematic search and screened for those implementing a psychological intervention with individuals with NDD (or caregivers) and measuring the potential impact on challenging behaviour. Of the 69 included studies published since 2018, more than 50% implemented a purely behavioural intervention. Other studies could generally be categorized as implementing parent training, meditation, skill training or technology-assisted interventions.

SUMMARY

Greater consideration of the interplay between behavioural and nonbehavioural intervention components; systematic approaches to personalization when going beyond the behavioural model; mental health and broad social communication needs; and models that include cognitive and emotional pathways to challenging behaviour; is needed to advance the field. Furthermore, technology should not be overlooked as an important potential facilitator of intervention efforts.

Interventions for Repetitive Behavior in Young Children with Autism: A Survey of Behavioral Practices

Children with autism spectrum disorder (ASD) display social-communication deficits and present with rigid and repetitive patterns of behavior and/or interests (RRBIs). Compared to interventions for social-communication skills, less attention has been given to RRBIs, especially with regard to interventions for young children. We surveyed 128 behavior analysts who implemented interventions for young children with ASD on their use of 16 practices and one assessment for the treatment of RRBIs. The majority of our sample perceived the practices to be effective in producing sustainable behavior change. Behavior analysts generally responded in the same way to items about reinforcement-based practices, punishment-based practices, and a group of commonly packaged antecedent and consequence-based package components. Implications and future directions are discussed.

A case study of suicidality presenting as a restricted interest in autism Spectrum disorder

BACKGROUND

Suicidality has been under-researched in autism spectrum disorders (ASD). Most studies have linked increased suicidality in ASD to psychiatric comorbidities such as depression. Here we investigated, from a neuropsychological and clinical standpoint, the relationship between core ASD symptoms, i.e., restricted behaviors and social and communication impairments, and the suicidal behaviors in an adult male individual with ASD, with no psychiatric comorbidities.

CASE PRESENTATION

We report the case of a 21-year-old male with ASD who attempted suicide twice, in the absence of other psychiatric diagnoses. His behavior and communication skills were rigid. His suicidality was characterized by a rigid, detailed, and pervasive thinking pattern, akin to restricted interests. Consistently, from a neuropsychological standpoint, we found below-average planning and attention skills, and mind-reading skills were rigid and lacked spontaneity.

CONCLUSIONS

Our case-study suggests that specific clinical and neuropsychological dimensions might be related to suicidal behaviors in ASD. Clinically, the repetitive and rigid suicide-oriented thinking of our patient was not part of a depressive episode. Instead, it followed a purely logical, inflexible, and pervasive reasoning pattern focused on a topic that fascinated him - i.e., suicide --, akin to restricted behaviors. From a neuropsychological standpoint, restrictive suicide-oriented thinking in our patient seems to be related to attention and executive anomalies that have been linked to repetitive and restricted behaviors in ASD. New tools need to be developed to assess persistent suicidal thoughts in this population, as they might be related to intrinsic features of ASD.
