ABSTRACT
Difficulty managing intense negative affect lies at the heart of many clients’ struggles with adjustment and mental health problems, in many cases ultimately prompting them to seek intervention. Indeed, clients frequently request “coping tools” for managing anxiety, sadness, anger, guilt, and other unpleasant emotional experiences. Over the past two decades, the constructs of emotion regulation and distress tolerance—both of which are relevant to these concerns—have received much attention, and the development of these approaches has yielded an array of tools that clients can use to manage negative affect.
