Acceptance and Commitment Therapy (ACT) is a is an evidence-based third-wave behavioral treatment that rests upon the idea that people's problems may worsen when they try to control or eliminate feelings or thoughts. ACT, therefore, is not aimed at symptom removal. Instead, it is about helping clients live meaningfully. ACT work is about interacting differently with our experiences – gaining distance from thoughts and feelings and behaving consistently with what we care about. Brief introductions to the ACT model's underlying philosophical stance (functional contextualism) and theoretical roots (relational frame theory) will be given prior to covering the six core processes of the ACT model. The majority of the 3-hour webinar will be devoted to the ways is which ACT assessment and treatment is carried out with youth who present with issues such as anxiety, depression, attention problems, behavioral disturbances, and high functioning autism. Integration of philosophy, theory, and application will be used to guide a dialogue about case conceptualization. Behavioral principles will be relied upon to discuss what works for whom in which circumstances as techniques are introduced. Participants are encouraged to bring de-identified case information to inform this illustrative experience.
