Panic attacks (PAs) are prevalent and highly comorbid with various physical and psychological disorders. Cognitive-behavioral therapy (CBT) is a well-established psychosocial intervention. Internet-delivered CBT (ICBT) presents a promising avenue to overcome barriers and provide evidence-based support to those in need. The current scoping review aimed to systematically map the existing literature and identify knowledge gaps regarding the impact of ICBT on outcome measures for individuals experiencing PAs. The PRISMA guidelines for scoping reviews were used. A total of 3,044 records were retrieved, and 18 studies from 2013 to 2023 were ultimately included in the analysis. ICBT demonstrated effectiveness as a psychosocial intervention for improving panic symptoms and anxiety in individuals with PAs. However, the impact of ICBT on quality of life (QOL) remains inconclusive. All studies included in this review focused on assessing the severity of panic symptoms, with limited emphasis on measuring QOL. This scoping review holds significant implications for research and practice. However, further addressing the research needs identified in this review will enhance our understanding and improve treatment outcomes for PAs.
