• Transdiagnostic treatments may optimize mental health services at this time. • The Unified Protocol (UP) is a promising transdiagnostic treatment for this context. • Adaptations of the UP for telehealth delivery are discussed. • Considerations specific to COVID-19 are reviewed. The COVID-19 pandemic has necessitated an abrupt transition to remote delivery of psychology services at a time when patients and practicing clinicians are experiencing an increase in life stressors (e.g., job loss, social isolation, need to adapt to telehealth practice), which can exacerbate mental health concerns and contribute to clinician burnout. Because the COVID-19 pandemic is affecting diverse individuals in myriad ways, these circumstances can elicit a wide range of emotions and emotional responses. Thus, treatment during this time must be able to address heterogeneous presenting problems while placing minimal burden on clinicians who are adjusting to continuously changing circumstances. Transdiagnostic, emotion-focused, cognitive behavioral treatments (CBT), such as the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP), may be particularly well suited to address the challenges faced by practicing psychologists, and their patients, in the current COVID-19 pandemic. This paper discusses the applicability and adaptability of transdiagnostic treatments to telehealth, focusing primarily on the UP in the context of the COVID-19 pandemic. Further, while many CBT skills (e.g., mindfulness) can be easily translated to tele-delivery, other skills, such as exposure, can be more difficult to implement remotely, especially in the midst of a pandemic. Thus, this paper also provides practical suggestions for clinicians with regard to implementing the UP remotely. [ABSTRACT FROM AUTHOR]
