Those working within the field of applied behavior analysis (ABA) encounter potential ethical dilemmas on a daily basis. While some challenges can be anticipated and appropriately addressed before they become unmanageable, oftentimes behavior analysts are confronted with unforeseen and novel situations that require immediate, yet careful attention. It is impossible to anticipate and plan for every eventuality. A Workbook of Ethical Case Scenarios in Applied Behavior Analysis, Second Edition, presents more than 120 real-world case scenarios commonly faced by individuals practicing ABA. The examples range in difficulty and severity to address the unique challenges and needs of those teaching, practicing, or learning ABA through ethics-focused coursework or preparing for the Behavior Analyst Certification Board® (BACB®) certification exam. In addition to case scenarios, the workbook provides detailed questions to facilitate discussion and critical thinking, offers suggestions related to the navigation of ethically precarious situations, and includes recommendations of ethics codes to consider in relation to each presented scenario.
