Autism spectrum disorder (ASD) is a relatively new diagnostic label which reflects the variability and differentiation of symptomatology among children and youth commonly described as having autistic disorder, high-functioning autism (HFA), and Asperger's syndrome. Current best practices have emerged from decades of evidence-based research, research-to-practice translation of empirically supported procedures, and consensus-driven recommendations from multiple disciplines. As a result, practitioners have many educational and intervention choices for children and youth with ASD - what is critical is that these options are informed by empirical outcomes that have been replicated in experimental trials (group and single-case) and disseminated to professionals and researchers alike. Children and Youth with Autism Spectrum Disorder (ASD) is a state-of-the-art volume of 15 chapters across four thematic sections that reflect the current convention of viewing autism along a continuum of presenting symptoms. Skillfully edited by James K. Luiselli, sections cover diagnosis, assessment, and measurement; evidence-based practices; health and development; and additional topics such as mindful caregiving and support, CBT, and behavioral family intervention. Compiling the most up-to-date advances in approaches toward diagnosis, education, treatment, and program development, Children and Youth with Autism Spectrum Disorder (ASD) will be a valuable resource for professionals and trainees in the ASD field including psychologists, educators, therapists, behavior analysts, and similar practitioners. It is also appropriate for academic researchers and courses devoted to clinical psychology, special education, developmental disabilities, and special topics.
