<p>Autism spectrum disorder (ASD) is a pervasive developmental disorder that is characterised by deficits in social communication and restricted and repetitive behaviours, interests and activities. Recent developments in identification techniques mean that many children can be reliably diagnosed with ASD before the age of 2. Early identification creates the opportunity for early intervention. In fact, some research suggests that the earlier a child with ASD receives intervention, the greater the progress he or she is likely to make. Naturalistic developmental behavioural interventions are a relatively recent method of early intervention for children with ASD, which combine elements of previous intervention approaches (behavioural, naturalistic behavioural, and developmental/relationship-focused intervention). One such naturalistic developmental behavioural intervention is the early start Denver model (ESDM), which is designed for children with or at risk for ASD between the ages of 12 and 60 months (5 years). Research suggests that ESDM intervention may improve a range of child outcomes when delivered for at least 15 hours per week over at least 10 months. However, many families may not be able to access or afford such intensive intervention. Therefore, the two studies in this thesis evaluated the effectiveness of two ESDM delivery approaches that required relatively few hours of professional input per week. Specifically, low-intensity therapist delivered ESDM intervention, and ESDM parent training.  Study 1 used a multiple probe across participants design to evaluate the effectiveness of 3 hours per week of home-based ESDM therapy for 12 weeks for improving imitation, communication, and engagement for four young children with ASD. It also examined whether children showed increases in these outcomes with their mothers following the intervention. The results of this study suggest that, following the intervention, all four children increased their imitation skills and their engagement with the therapist. In addition three of the children had more functional utterances and one child increased his use of intentional vocalisations. These results were maintained four weeks after intervention and generalised to a lesser degree to each child’s mother. This suggests that low-intensity therapist delivered ESDM intervention may improve outcomes for children with ASD.  The results of Studies 1 and 2 suggest that both low-intensity therapist delivered ESDM intervention and ESDM parent training may be promising intervention approaches for young children with ASD. This is particularly encouraging as both approaches involved relatively few hours of professional input per week. In theory, this could increase the number of families who are able to access such intervention. More research is needed to identify the most effective low-intensity ESDM intervention method, or combination of methods.</p>

<p>Autism spectrum disorder (ASD) is a neurodevelopmental disorder defined by difficulties in social communication and the presence of restricted or repetitive behaviours or interests. There is evidence to suggest that early intervention (EI) can lead to improved outcomes for children with ASD. Inclusive preschool-based delivery of EI appears to satisfy current legal and best-practice recommendations around the delivery of EI for young children with ASD. It may also offer several potential benefits including cost-effectiveness, efficiency and opportunities for children with ASD to learn from their peers. The Early Start Denver Model (ESDM) is a promising naturalistic behavioural developmental intervention for young children with ASD aged between 12 and 60 months. The ESDM can be delivered to children in a group-based format and several studies have demonstrated its effectiveness when delivered for 15 to 25 hours per week in designated ESDM preschools with low child–teacher ratios. However, the preschools involved in these studies may not be representative of the typical preschool setting for many communities. Thus, more research is needed to determine the effectiveness of this intervention when delivered under conditions that more closely reflect the typical real-world preschool setting.  In the present thesis, two studies with multiple probe across participants designs, each involving three preschool children with ASD, examined the feasibility and effectiveness of the use of the ESDM in an inclusive preschool setting. Specifically, Study 1 evaluated the effectiveness of a modified version of ESDM therapy delivered by a certified therapist and Study 2 evaluated (a) the effectiveness of a brief ESDM coaching programme, and (b) the effectiveness of a modified version of ESDM therapy delivered by preschool teachers. For both studies, the intervention was delivered in regular community preschools and no major changes were made to the typical preschool environments or routines. Effectiveness was assessed by measuring improvements in child active participation, vocal/verbal communication and imitation, and, for Study 2, teachers’ fidelity of implementation of ESDM techniques. Teachers’ perceptions of the acceptability and effectiveness of the intervention were also assessed via a questionnaire and in-depth interviews.  In Study 1, an outside certified therapist delivered 3 hours per week of ESDM to three children with ASD over an 8- to 10-week period. Participants showed improvement in active participation, imitation and either intentional vocalisations or spontaneous functional utterances. These results were generally maintained at follow-up. For Study 2, a brief coaching programme was used to train three preschool teachers to use the ESDM with a child with ASD who attended the inclusive preschools where they worked. Teachers improved in their use of the ESDM strategies and children demonstrated improved levels of active participation but results for child imitation and communication were mixed. Teachers also found the intervention to be acceptable and effective. Together, the results from these studies provide preliminary support for the feasibility and effectiveness of the ESDM when delivered in real-world inclusive preschool settings. More research is needed to determine the most effective approach to delivering EI for ASD in an inclusive preschool setting. It may also be valuable to evaluate the extent to which gains made by children and teachers during intervention generalise to other people and/or settings.</p>

Contemporary parent-implemented early intervention programs for children with autism spectrum disorder usually incorporate a range of techniques with different theoretical underpinnings. While research suggests that parents often learn to implement interventions with an acceptable degree of overall fidelity, there is limited research into parent use of individual intervention techniques. This study included five mothers of young children with autism spectrum disorder who participated in a 12-week parent training program based on the Early Start Denver Model. Ten-minute play samples were coded for the mothers’ use of 18 specific Early Start Denver Model techniques before, during, and 1 month after the training program. The correlation between the mothers’ use of each Early Start Denver Model technique and their child’s level of engagement and expressive language was also calculated. Results suggest that all mothers increased the number of techniques that they were using from baseline to parent training. Some Early Start Denver Model techniques were moderately or strongly correlated with both child engagement and expressive language. There was considerable variation in outcomes across all mother–child dyads. These preliminary results have implications for how parents are trained/coached to implement interventions for young children with autism spectrum disorder. Lay abstract Parents of young children with autism are often taught to deliver interventions which involve several different types of strategies. Research suggests that parents can usually learn to deliver these interventions but not much is known about their use of each specific intervention strategy. This study included five mothers of young children with autism who participated in a 12-week parent training program based on the Early Start Denver Model. We measured their use of 18 different ESDM strategies before, during, and 1 month after the training program. We found that parents increased the number of strategies that they used during the training program. There were differences between mothers in terms of the ESDM strategies that they used the most during the training. We also found that some of the strategies were more closely related to children’s levels of engagement and language than others. This suggests that parent training should be adapted to suit each parent’s needs.

Telehealth training may benefit parents’ use of early intervention for children with autism spectrum disorder (ASD). This study is one of the few randomized trials to compare telehealth parent training in the Early Start Denver Model (P-ESDM) with a community treatment-as-usual, early intervention program. Parents were randomized to 12 weekly 1.5-hr videoconferencing sessions with website access to P-ESDM learning resources or to monthly 1.5-hr videoconferencing sessions with website access to alternative resources to support their intervention. Telehealth training facilitated higher parent fidelity gains and program satisfaction for more of the P-ESDM than the community group at the end of the 12-week training and at follow-up. Children’s social communication skills improved for both groups regardless of parent fidelity. Findings suggest the feasibility of telehealth training with improved parent intervention usage and satisfaction from the program. However, the impact of these effects on children’s development over time is yet to be understood.

The Early Start Denver Model is an evidence-based, comprehensive naturalistic developmental behavioral intervention. Randomized controlled studies indicate that long-term, high-intensity Early Start Denver Model in home-based settings can positively impact the clinical outcomes of young children with autism spectrum disorder. However, it is difficult to deliver high-intensity early intervention in an under-resourced country such as Taiwan. This study evaluated the effects of implementing the Early Start Denver Model with adaptations (including low intensity, shorter duration, and delivery in general hospitals by multidisciplinary professionals) within the Taiwanese public health system. A pre- and post-intervention study was conducted. Sixteen children with autism spectrum disorder (mean age of 33.5 months) received 6 months of one-on-one Early Start Denver Model intervention (approximately 8 h per week). The children showed significant post-intervention improvements in language and overall cognitive functioning and reduced symptom severity in communication and play. This study suggests that delivering the Early Start Denver Model in community-based hospitals may be an effective intervention, with a wider reach, for young children with autism spectrum disorder in Taiwan. The next steps in Taiwan are to incorporate a control group and assess the long-term effects of the adapted Taiwanese Early Start Denver Model program. Lay Abstract The Early Start Denver Model is a comprehensive naturalistic developmental behavioral intervention for young children with autism spectrum disorder. Rigorous studies indicate that long-term, high-intensity Early Start Denver Model in home-based settings can help young children with autism spectrum disorder have great progress in language, cognitive development, and adaptive skills and reduce overall symptom severity. In accordance with the current limitations in resourcing for early intervention in Taiwan, this study evaluated the effects of implementing the Early Start Denver Model in the Taiwanese public health system with some adaptations, including lower intensity, shorter duration, and delivery in general hospitals. A total of 16 children with autism spectrum disorder, aged between 25 and 46 months, received approximately 8 h per week one-on-one Early Start Denver Model intervention. After 6 months of intervention, the children showed great improvements in language and overall cognitive functioning and reduced symptom severity in communication and play. This study suggests that directly delivering the Early Start Denver Model in community-based hospitals may be an effective intervention, which can make more young children with autism spectrum disorder in Taiwan access the Early Start Denver Model service.
