Practical Ethics for Effective Treatment of Autism Spectrum Disorder, Second Edition is for behavior analysts working directly with, or supervising those who work with, individuals with autism. The book addresses the principles and values that underlie the Behavior Analyst Certification Board’s® Professional and Ethical Compliance Code for Behavior Analysts and factors that affect ethical decision-making. In addition, the book addresses critical and under-discussed topics, including scope of competence, evidence-based practice in behavior analysis, how to collaborate with professionals within and outside one’s discipline, and how to design systems of ethical supervision and training customized to unique treatment settings. Across many of the topics, the authors also discuss errors students and professionals may make during analyses of ethical dilemmas and misapplications of ethical codes within their practice. New to this revision are chapters on Quality Control in ABA Service Delivery, Ethical Issues in ABA Business Management and Standardizing Decision-making in ABA Service Delivery.
