Compassion is generally defined as a desire and willingness to alleviate the suffering of others. Though there is no doubt that applied and clinical behavior analysis were founded with such intentions, compassionate behavior has not historically been explicitly analyzed or taught in behavior analytic practice. Though the word “compassion” does not often appear in traditional behavior analytic literature, it is now being employed more regularly in formal contexts and has even found its way into the most recent BACB code of ethics. As scientific practitioners, it is important that behavior analysts establish an agreed upon functional and actionable definition of compassion so that they can effectively plan for, engage in, and train others to engage in, compassionate practices. Behavior analysts have both the technology and the heart to spread compassion far and wide. This panel will discuss the functional conceptual definitions of compassionate behavior so that we can learn to identify it and understand that the topography will vary across individuals, groups, cultures, and contexts. The panel will also address how to plan for and respond with compassion to harmful behaviors. Perhaps most crucially, the panel will discuss compassion’s close relationship with self-compassion, ways to practice self-compassion and strategies aimed at avoiding compassion fatigue.
