Advantages and Challenges of a Home- and Clinic-Based Model of Behavioral Intervention for Individuals Diagnosed with Autism Spectrum Disorder

Tele-Assisted Behavioral Intervention for Families with Children with Autism Spectrum Disorders: A Randomized Control Trial

Background: Telehealth is useful for both autism spectrum disorder (ASD) diagnosis and treatment, but studies with a direct comparison between teletherapy and traditional in-person therapy are limited. Methods: This randomized control trial—ISRCTN (International Standard Randomised Controlled Trial Number) primary clinical trial registry ID ISRCTN15312724—was aimed at comparing the effect of a tele-assisted and in-person intervention based on a behavioral intervention protocol for families with children affected by ASDs. Forty-two parents with children with autism (30 months to 10 years old) were randomly assigned to 12 sessions of an applied behavioral analysis (ABA) intervention implemented in an individual and group setting, either with or without the inclusion of tele-assistance. Pre- and postintervention assessments were conducted using the Home Situation Questionnaire (HSQ-ASD) and the Parental Stress Index (PSI/SF). Results: Substantial improvements in the perception and management of children’s behavior by parents, as well as in the influence of a reduction in parent stress levels on said children’s behavior through the use of a tele-assisted intervention, were obtained. Conclusions: This randomized controlled trial demonstrates the evidence-based potential for telehealth to improve treatment of ASDs.

Effects of a low-intensity Early Start Denver Model-based intervention delivered in an inclusive preschool setting

The Early Start Denver Model (ESDM) is a promising early intervention for promoting improved social, cognitive, and communication outcomes for young children with autism spectrum disorder (ASD). However, most studies evaluating group-based delivery of this program have used 15-25 h per week of intervention in specialized ESDM preschools with low child-teacher ratios. Thus, the positive results from such studies might not be obtained when this intervention model is evaluated in more typical inclusive preschool settings. In this study, a low-intensity version of the ESDM was delivered to three young children with ASD in their regular inclusive preschool by a certified therapist who did not typically work at any of the preschools. The intervention procedures were implemented for 3 h per week over an 8- to 10-week period. Data were gathered on children's levels of participation, imitation, and communication from weekly 10-min video recordings. The effects of the intervention were evaluated using a multiple probe across participants design with 3 weekly follow-up probes, 3 weeks after the intervention ended. All participants showed improvement in active participation, imitation and either intentional vocalizations or spontaneous functional utterances. These results were generally maintained at follow-up. This low-intensity version of the ESDM would seem effective for use in real-world preschool environments.

Treatment of avoidant/restrictive food intake disorder for a teenager with typical development within the home setting

INTRODUCTION

Avoidant/restrictive food intake disorder (ARFID) can occur in children with typical development and persist past childhood. This significantly impacts most areas of children's lives, but may become more evident in teenage years, especially socially. There is an empirically supported treatment for ARFID with 40 years of research backing, this being behaviour-analytic feeding interventions. However, application to individuals over age 12 is lacking, and needs to be investigated for effectiveness. This is important as the addition of ARFID (formerly called feeding disorders) to the DSM-V has seen an increase in new treatments for ARFID by attempting to apply eating disorder treatments to this population including children. More research is needed to identify if already established behavioural intervention procedures are effective for ARFID in individuals with selectivity, without disabilities, older ages, and in settings outside of intensive specialised feeding hospital admissions in the United States.

METHOD

A 13-year-old female with ARFID and years of failed treatment attempts participated in her home in Australia. We conducted multiple stimulus without replacement preference assessments and used a changing criterion design with multiple baseline probes. Treatment consisted of demand fading, choice, differential attention, and contingent access. We did not use cognitive or family based treatment.

RESULTS

Consumption increased to 100%. Variety reached 61 foods across all food groups. She met 100% of goals and ate at a restaurant. Caregivers reported high satisfaction and social acceptability. Gains were maintained at 9 months.

CONCLUSION

This brief, behaviour-analytic in-home treatment was effective in increasing food group variety consumption.
