In cognitive-behavioral therapy (CBT) for child and adolescent anxiety disorders, negatively evaluated thoughts and emotions are viewed as problematic responses to be managed via control-oriented strategies such as distraction, systematic desensitization, self-instruction, or cognitive restructuring. Within this framework, anxiety is conceptualized as “the problem,” and symptom reduction is a standard index of treatment success. Acceptance- and mindfulness-based therapies such as acceptance and commitment therapy (ACT; Hayes, Strosahl, & Wilson, 1999) differ from standard CBT primarily in their treatment of private events (e.g., thoughts, emotions, physical-bodily sensations, memories).
