Introduction to Treatment  
of Autism Spectrum Disorder (ASD)

of Autism Spectrum Disorder (ASD)

INTRODUCTION

INTRODUCTION
This book is intended to introduce readers who have some familiarity with autism 
spectrum disorder (ASD) and its core impairments to a group of interventions 
focused on social communication and social interaction. Because the diagnostic 
category for autism has undergone modification since the first edition of this text, 
this chapter describes these changes and briefly highlights some implications for 
these changes. The chapter then provides updates on national reviews of interventions considered to be established in support of the social communication and

social interaction of children with ASD.

CHANGES TO THE DSM-5
When the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision (DSM-IV-TR; American Psychiatric Association [APA], 2000) 
was updated to DSM-5 (APA, 2013), pervasive developmental disorder/autism, with 
its subthreshold diagnoses, changed to autism spectrum disorder. The diagnostic 
criteria also moved from three primary diagnostic categories to two: 1) social communication and social interaction and 2) restricted, repetitive, and stereotyped 
patterns of behavior. Expansion within each category also occurred. Table 1.1a summarizes differences between the earlier (DSM-IV-TR, APA, 2000) and the current 
characterization of ASD (DSM-5; APA, 2013). A particularly significant change is 
that language and cognition are now considered to be potential comorbid conditions and require a separate assessment to ensure deficits in these areas cannot be 
better explained by an intellectual disability (ID) or a global developmental delay.

Table 1.1b describes the severity levels now associated with each of the two primary

Several implications are discussed in the literature regarding the application 
of the new DSM-5 criteria. For example, Young and Rodi (2014) found only 57.1% of 
those with pervasive developmental disorders (PDDs) on the DSM-IV met the criteria for DSM-5, whereas 50%–75% maintained diagnoses in a review completed by 
Smith and colleagues (2015). In both studies, children with a diagnosis of PDD-not 
otherwise specified (PDD-NOS) and Asperger’s disorder were less likely to meet the 
DSM-5 criteria, specifically all three social communication and social interaction

the new criteria continue to receive the intervention services they require (Smith 
et al., 2015; Young & Rodi, 2014).
A study with 185 children under 5 years old indicated that children with autism 
on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, 
Text Revision (DSM-IV-TR; APA, 2000) were also diagnosed with ASD on the DSM-5, 
but children with previous PDD-NOS diagnoses had fewer comorbid and emotional 
behaviors and insufficient symptoms in the restricted repetitive patterns of behavior category to qualify for an ASD diagnosis (Christiansz et al., 2016). Another 
study (Zander & Bolte, 2015) of younger children between 20 and 47 months found 
that 12%–67% of the children who met the DSM-IV-TR criteria did not meet the

consistent diagnosis. Reports by the Centers for Disease Control and Prevention 
(Baio et al., 2018), however, indicate the number of children meeting the DSM-5 criteria for ASD as compared to the DSM-IV-TR criteria are fairly similar, with DSM-IV-
TR cases exceeding DSM-5 cases by less than 5% and with an 86% overlap between 
the two definitions. It remains unclear what the impact has been or will be to the 
prevalence of ASD diagnoses with the addition of social communication disorder 
(APA, 2013). Although this disorder is characterized by challenges in the social use 
of both verbal and nonverbal communication similar to ASD, there is no evidence of 
restricted and repetitive patterns of behaviors, interests, or activities. Whatever the 
ultimate impact is of the application of the DSM-5 on the diagnosis of ASD, children 
still require evidence-based interventions that address their social communication 
and social interaction impairments, as prevalence numbers continue to rise with 1

in 59 children receiving a diagnosis (Baio et al., 2018).
BACKGROUND ON INTERVENTION STRATEGIES

FOR COMMUNICATION AND SOCIAL INTERACTION
Since 2000, thinking has evolved about which intervention approaches are most 
appropriate for supporting the social interaction and communication needs of children with ASD as well as children with social pragmatic disorders who may not 
meet the ASD diagnosis. Although traditional behavioral interventions are 
plentiful in the literature (e.g., Cooper et al., 2007) and tremendously influential in 
a variety of settings (Downs et al., 2007; Lafasakis & Sturmey, 2007; Taubman et al., 
2001), social-pragmatic developmental interventions continue to gain traction, 
including those that involve parent training, in part because they emphasize opportunities for people with ASD to establish positive social connections and generalize 
their skills in the natural environment. Interest in these approaches has also arisen 
in response to limitations identified in traditional behavioral approaches to ASD in 
terms of generalization of targeted behaviors, particularly those related to the social 
use of communication and language (Wetherby & Woods, 2006, 2008). This book 
focuses primarily on such approaches because of their special promise in addressing 
the social communication and social interaction challenges at the core of ASD and

have more recently been elaborated upon and modified to address the special challenges presented by ASD.
Several of the interventions described in this text capitalize on the value of 
integrating the best of behavioral and developmental approaches to achieve functional and relevant social and communicative outcomes for children, adolescents, 
and adults with ASD. For example, Prizant and Wetherby (1998), recognizing the

Introduction
to intervention, proposed contemporary behavioral interventions (i.e., middle 
ground interventions) to support the communication and social interaction needs 
of children with ASD. In particular, they described the value of giving children 
choices, sharing communication opportunities between the interventionist and the 
child, and using preferred activities and materials—strategies that characterize pivotal response training (Koegel, Koegel, Harrower, & Carter, 1999; Koegel, Koegel,

otal response training (Koegel, Koegel, Harrower, & Carter, 1999; Koegel, Koegel, 
Shoshan, & McNerney, 1999).
As intervention approaches have evolved, so too have comprehensive guidelines for best practices. In 2001, the National Research Council (NRC) offered a 
description of best practices for children with ASD through the early childhood 
years. A number of intervention guidelines emerged from a comprehensive review 
of the literature, including initiating treatment as soon as possible; ensuring active 
engagement during intensive instruction; using developmentally appropriate, 
goal-based, and systematically planned activities; implementing planned teaching 
opportunities throughout the day; and involving families and peers in the intervention to facilitate generalized skill learning. Many early intervention programs have 
used these best practices to design comprehensive educational programs for young

used these best practices to design comprehensive educational programs for young 
children with ASD.
As a follow-up to the NRC (2001) description, Iovannone and colleagues (2003) 
proposed six educational practices as appropriate and effective for school-age children with ASD: 1) providing individualized supports and services that matched a 
student’s profile as defined through the individualized education program (IEP) 
process; 2) offering systematic, carefully planned, and defined instructional procedures to achieve valid goals with a process for measuring outcomes; 3) creating a 
structured learning environment; 4) adding specialized curriculum content in the 
area of social engagement and recreation and leisure skills; 5) defining a functional 
approach to problem behaviors; and 6) engaging families in their student’s educational success. Challenges remained, however, in determining the most effective 
instructional procedures for children of varying ages, language abilities, and cognitive levels with diagnoses of autism and subthreshold diagnoses, such as Asperger

approaches were identified as making a significant contribution but requiring more 
research (NAC, 2009).
In 2015, the NAC published a second report, examining research from 2007 to 
2012, including any intervention research for those with ASD over 22 years of age 
(from 1987 to 2012), collapsing a couple of the behavioral packages under behavioral 
interventions and adding a couple of intervention categories. Their findings continued to support behaviorally based interventions, although limited research was 
found for adults over 22, with only 28 studies meeting the inclusion criteria, find-

with ASD. Notably, however, the 2015 NAC report added three interventions to the 
established category for individuals from birth to age 21: 1) language training (specifically language production using behavioral principles); 2) parent training; and 
3) a social skills package. The report’s chapter on behavioral interventions speaks 
to some of the more recent work in language production training. This second edition of Treatment of Autism Spectrum Disorder includes two new chapters that 
involve parent training, which adds to the three chapters from the first edition that 
already focus on the value of parent training, and this edition also features a new

already focus on the value of parent training, and this edition also features a new 
chapter on social skills training.
Table 1.2 lists the 14 interventions included in this book according to their level 
of evidence at the time of the most recent publication of the National Standards 
Project (NAC, 2015). Established treatments are those identified with sufficient evidence leading to positive outcomes. Emerging treatments are those with one or more 
studies yielding positive outcomes but requiring additional high-quality studies to 
show consistent results. Unestablished treatments are those with little evidence and 
that consequently require additional research. No treatments are those judged to be 
ineffective or harmful. Interventions described in this book fall primarily within the 
top two categories of evidence—established and emerging; only one intervention

Introduction
training, which is an established intervention. Also, three interventions are included 
that relate specifically to parent training (i.e., Early Denver Start Model [Chapter 5], 
®
Early Social Interaction Project [Chapter 11], and The SCERTS Model [Chapter 14]) 
that were not specifically named in the 2015 NAC National Standards Project report. 
With the National Standards Project as a guide for evidence-based practice with 
children and youth affected by ASD, this text is timely because it emphasizes key 
established and emerging interventions used to facilitate the communication and 
social interaction of individuals with ASD and highlights those interventions with

parents playing a key role.

PURPOSE OF THE BOOK
This book describes and critically analyzes specific treatment approaches used to 
address the communication and social interaction challenges of children, adolescents, and adults with ASD. Although these challenges are of specific interest to 
speech-language pathologists, providers across disciplines have a stake in using 
evidence-based intervention to respond to these core areas of impairment for 
individuals with ASD. Approaches selected for inclusion have empirical evidence 
of efficacy or effectiveness established through systematic reviews or at least two 
peer-reviewed articles that indicate the approaches are well-established, probably 
efficacious or promising emerging interventions (e.g., Chambless et al., 1998; Chor-

to access the video clips).
Readers will learn that the interventions emphasize somewhat different prin-

instances of randomized control trials do exist (e.g., joint attention training using 
the JASPER model).
Table 1.3 provides a summary to facilitate the reader’s understanding of the 
similarities and differences among the interventions in terms of basic principles, 
techniques, teaching methods, treatment targets, and ages for which evidence has 
been established. This table also identifies the evidence rating provided by the 
National Autism Center (2015). In addition, to make the treatments accessible to 
the reader and to facilitate their comparison, the table’s descriptions were standardized using a template adapted from that used in McCauley and Fey (2006) in which 
critical features of each treatment are highlighted. Treatments are also illustrated 
by a short video example, which can be accessed on the Brookes Download Hub (see

development in children, adolescents, and adults with ASD; therefore, there is 
not one best approach for all individuals. Instead, there are profiles of individuals 
affected by ASD who are likely to benefit most from each intervention guided by 
the evidence. Early, intensive, and structured intervention as well as a collaborative 
approach to working in home, educational, and community settings appear to be 
critical features of effective intervention. Further, this book emphasizes the impor-

tance of addressing the core deficits of social interaction and social communication.

HOW TREATMENTS ARE DESCRIBED

HOW TREATMENTS ARE DESCRIBED
Authors prepared their intervention chapters, Chapters 4–17, using a template, with 
sections indicated by the headings provided in Table 1.4. Each chapter begins with a 
brief introduction summarizing the treatment approach and defining the subgroups 
of individuals with ASD for whom the treatment is designed. The chapter also 
includes the age, developmental level, language level, and service delivery model the 
treatment entails, including its basic focus and methods. In the description of the 
subgroups for whom the intervention is appropriate, the authors consider not only

The next section in each chapter includes the theoretical basis for the treatment 
approach. Here the authors discuss four main components. The first component is 
a theoretical explanation or rationale for the treatment. The second component 
includes underlying assumptions regarding the nature of the communication and 
social interaction impairment being addressed by the treatment. The third compo-

social functioning).
The theoretical basis is followed by a summary of research providing an empirical basis for the treatment. In this section, the authors summarize and interpret 
studies providing evidence that supports the use of the treatment. Authors have 
prepared a level of evidence table in which they present the major research designs 
used to examine the intervention and the outcomes reported for both group and 
single-subject research. Where possible, effect sizes are reported as originally pub-

discussion of time demands, training, or expertise required by clinicians wishing to use the intervention and any materials or equipment needed for treatment 
implementation.
Practical requirements are followed by a description of the key components of 
the intervention approach. The goal for this section is to ensure the reader has a 
strong, preliminary understanding of the procedures. Authors provide information 
about the nature of the goals addressed by the intervention, how multiple goals are 
addressed over time (e.g., sequentially, simultaneously, cyclically), a procedural or 
operational description of activities within which the goals are addressed, and the 
nature of involvement of participants beyond the clinician and child (e.g., peers, sib-

single-subject research. Where possible, effect sizes are reported as originally published or computed for the chapter when means and standard deviations were given.
To support practitioners’ use of the described interventions in their specific 
settings, in the next section of each chapter, authors outline some practical requirements for implementing the treatment. This section of each chapter includes a 
discussion of time demands, training, or expertise required by clinicians wishing to use the intervention and any materials or equipment needed for treatment

Introduction
Chapter 3 highlights the language and communication strengths and challenges 
most often seen in children with ASD, as these have implications for intervention. 
Early communication challenges are discussed, including intentional communication, gesture use, word learning, and the use of unconventional verbal behavior. The 
chapter emphasizes those challenges that specifically impact language development, 
social communication, and social interaction, such as impairments in joint attention, 
play, and theory of mind. This chapter is designed to help the reader understand 
what researchers know about the syntactic, semantic, phonological, and pragmatic

interaction challenges as well as the possible strategies that can help address them.

what researchers know about the syntactic, semantic, phonological, and pragmatic 
development of children with ASD and what the implications are for intervention.
In addition to these changes in the content included in this second edition, a 
companion resource, Case Studies for the Treatment of Autism Spectrum Disorder (Prelock & McCauley, 2021), is offered as an optional supplementary resource. 
Through 14 individual cases, readers are introduced to hypothetical but instructive scenarios posing the kinds of clinical problems that face clinicians who wish 
to devise comprehensive services for clients with ASD. Although there is particular 
focus on social communication and social interaction difficulties, the multitude of 
co-occurring problems that so often complicate the decision making required for 
effective management in ASD are incorporated to provide a real-world flavor. Alongside decisions recommended by experts, the casebook includes decision-making 
exercises that can enrich readers’ understanding of social communication and social

"Would make an excellent text for a course in treatment of ASD, as well as a great resource for practitioners searching to find the most appropriate treatments for a wide range of individuals with ASD."

—Rhea Paul, Ph.D., CCC-SLP, HASHA, Professor and Chair Department of Communication Disorders, Sacred Heart University

"No single book can possibly capture all one needs to know for supporting learners with autism, but this volume is an excellent foundation for the journey."

Mareile Koenig, Ph.D., CCC-SLP, BCBA, Professor and SLP Graduate Program Coordinator, Communication Sciences and Disorders, West Chester University

To work effectively with individuals who have autism spectrum disorder (ASD), SLPs and other practitioners need in-depth knowledge on choosing and implementing interventions for communication and social challenges. This bestselling textbook gives professionals the foundation they need to evaluate and compare today's widely used interventions—and determine which ones will promote the best outcomes for the people they serve.

Readers will get a thorough introduction to 14 evidence-based interventions, complete with key details on each intervention's theoretical and empirical basis, components, practical requirements, applications for both children and adults, and considerations for children from diverse cultural and linguistic backgrounds. Twelve video clips (available for streaming) illustrate the interventions in action, and in-text learning activities prepare SLPs and other practitioners to make sound decisions in scenarios they're likely to encounter in the field.

- New chapter on language and communication strengths and challenges often seen in children with ASD

- New chapter on assessment for treatment planning and progress monitoring

WHAT'S NEW:

- Videos to demonstrate the newly added interventions

- New in-depth profiles of the Early Start Denver Model, The SCERTS $ ^{\circledR} $ Model,and Social Skills Interventions

- Updates to reflect the DSM-5

- More information on inclusive practices

- More on working with children from culturally and linguistically diverse backgrounds

COMPANION CASEBOOK AVAILABLE: Available on its own or as a bundle with the textbook, Case Studies for the Treatment of Autism Spectrum Disorder walks readers through 14 realistic cases and helps them hone their decision-making skills.

- A sample syllabus that demonstrates how faculty can integrate this book into a course
