Integrating Mindfulness and Acceptance Into Traditional Cognitive Behavioral Therapy During the COVID-19 Pandemic: A Case Study of an Adult Man With Generalized Anxiety Disorder.

Generalized Anxiety Disorder (GAD) can be chronic and impairing, highlighting the need for effective treatments. Although Cognitive Behavior Therapy (CBT) is an effective treatment for GAD, a number of patients continue to report GAD symptoms treatment. Integrating evidenced-based treatment components into CBT treatments, such as mindfulness- and acceptance-based treatment components found in Acceptance and Commitment Therapy (ACT), may help improve the efficacy of treatment. Emerging interventions and research suggest that the cognitive restructuring aspect of CBT and acceptance stance of ACT (e.g., cognitive defusion) can be implemented into treatment concurrently from a stance of increasing a patient's coping skills repertoire and psychological flexibility. This systemic case analysis examined the efficacy and clinical utility of integrating ACT into a manualized CBT treatment for GAD. Furthermore, this study examined treatment efficacy and therapeutic alliance as the treatment rapidly and unexpectedly transitioned from in-person to telehealth due to the COVID-19 pandemic. Pre- to post-treatment and time-series analyses showed significant decreases in anxiety symptoms, worry, depressive symptoms, and emotion dysregulation. Although there was an initial increase in depressive and anxiety symptoms, worry, and emotion dysregulation following the switch from in-person to telehealth services, these quickly subsided and resumed a downward trend. The therapeutic relationship did not deteriorate during the transition to telehealth. This case study provides evidence of feasibility and efficacy of an integrated CBT/ACT approach in treating GAD. It also suggests that despite some temporary increase in symptoms, therapeutic alliance and treatment efficacy were not impacted by the switch to telehealth.
