Characterizing caregiver responses to restricted and repetitive behaviors in toddlers with autism spectrum disorder

Scoping review of behavioral coding measures used to evaluate parent responsiveness of children with autism or elevated risk of autism

LAY ABSTRACT

The topic of how parents react (e.g., how they talk and act) to their child with autism or elevated likelihood of autism, often called parent responsiveness, has been studied by researchers for over 50 years. Many methods for measuring behaviors around parent responsiveness have been created depending on what researchers were interested in discovering. For example, some include only the behaviors that the parent does/says in reacting to something the child does/says. Other systems look at all behaviors in a period of time between child and parent (e.g., who talked/acted first, how much the child or parent said/did). The purpose of this article was to provide a summary of how and what researchers looked at around parent responsiveness, describe the strengths and barriers of these approaches, and suggest a "best practices" method of looking at parent responsiveness. The model suggested could make it more possible to look across studies to compare study methods and results. The model could be used in the future by researchers, clinicians, and policymakers to provide more effective services to children and their families.

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.

Teachers' perceptions of Restricted and Repetitive Behaviours (RRBs) in children with ASD: Attributions, confidence and emotional response

BACKGROUND

Restricted and Repetitive Behaviours (RRBs) are some of the most difficult behaviours to manage in children with Autism Spectrum Disorders (ASD). Although RRBs frequently occur in educational settings, we know little about the way in which teachers understand these behaviours.

AIMS

The study aimed to explore the attributions, emotional response and feelings of confidence held by teachers working in different educational settings when faced with RRBs.

METHODS AND PROCEDURES

A single group survey design using behavioural vignettes was adopted in order to elicit teacher beliefs and ratings.

OUTCOMES AND RESULTS

Analysis indicated that there were differences in the attributions and confidence ratings held for different types of RRBs. Significant differences were also observed between teachers working in mainstream and specialist educational settings. Emotional response and confidence scores were often predictive of one another alongside factors related to teaching experience.

CONCLUSION AND IMPLICATIONS

The findings indicate that teachers from mainstream schools potentially hold less helpful beliefs in response to RRBs and therefore are a professional group who may benefit the most from additional support and training. Further research could consider conducting a qualitative exploration of why teachers hold certain beliefs about RRBs and/or sampling those who are less experienced in working with children with ASD.

Sensory Behaviors in Minimally Verbal Children With Autism Spectrum Disorder: How and When Do Caregivers Respond?

Sensory behaviors are widely reported in autism spectrum disorder (ASD). However, the impact of these behaviors on families remains largely unknown. This study explored how caregivers of minimally verbal children with ASD responded to their child's sensory behaviors. Using a mixed-methods approach, we examined two variables for each endorsed child behavior: (1) Did the caregiver respond/try to change the behavior? and (2) What response did they employ? Caregivers did not differ in the frequency of responses to hypo- or hyper-responsive behaviors but employed different responses. Caregivers responded to more social sensory behaviors and predominately changed their own behavior in response to their child's. Our findings demonstrate how extensively caregivers adapt to their child's behaviors and vary their response dependent on behavior exhibited.

Brief Report: Reduced Restricted and Repetitive Behaviors after Pivotal Response Treatment

Children with ASD show high frequency of restricted and repetitive behaviors (RRBs); however, higher-order RRBs, such as restricted interests, have remained largely resistant to treatment. This study evaluated change in severity of RRBs following a 16-weeks open trial of Pivotal Response Treatment (PRT). Participants included 15 children with ASD ages 4-7 years. RRBs, as measured by the repetitive behavioral scales-revised (RBS-R) and aberrant behaviors checklist, decreased significantly after treatment. These reductions remained significant after controlling for change in social communication skills. PRT shows promise in reducing RRBs; although PRT explicitly addresses pivotal social communication skills, there is a secondary and less direct effect on RRBs.

How Are Child Restricted and Repetitive Behaviors Associated with Caregiver Stress Over Time? A Parallel Process Multilevel Growth Model

The impact of raising a child with autism spectrum disorder (ASD) is frequently accompanied by elevated caregiver stress. Examining the variables that predict these elevated rates will help us understand how caregiver stress is impacted by and impacts child behaviors. This study explored how restricted and repetitive behaviors (RRBs) contributed concurrently and longitudinally to caregiver stress in a large sample of preschoolers with ASD using parallel process multilevel growth models. Results indicated that initial rates of and change in RRBs predicted fluctuations in caregiver stress over time. When caregivers reported increased child RRBs, this was mirrored by increases in caregiver stress. Our data support the importance of targeted treatments for RRBs as change in this domain may lead to improvements in caregiver wellbeing.
