As the number of behavior analysts practicing internationally grows, there is an increasing need for our field to navigate complex social and cultural differences while remaining in line with our fundamental philosophies and our professional and ethical guidelines. Across the United States and the world, differences abound in the acceptability of certain behaviors, the treatment of individuals with disabilities, the use of reinforcement and punishment, and the role of religious, educational, and governmental institutions. The expansion of our field into new markets and areas of practice has outpaced our ethics and compliance code, and many practitioners need to balance social validity and cultural sensitivity with professional guidelines. This panel discussion will bring together practitioners from around the world to share experiences in delivering behavioral services in an increasingly multicultural society. Topics to be addressed include the use of punishment, prioritizing treatment goals, selecting reinforcers, navigating religious and cultural beliefs, and legal and ethical compliance issues.
