Committee Members' Signatures: Beverly White, PsyD, Chairperson Robert A DiTomasso, PhD, ABPP Jesus Salas, PsyD Robert A DiTomasso, PhD, ABPP, Chair, Department of Psychology PANIC TREATMENT iii Acknowledgements I would like to thank my committee that helped me through this journey: Dr. Brad Rosenfield, Dr. Robert DiTomasso, and Dr. Jesus Salas. Their feedback and guidance was instrumental in the success of this study. I would also like to thank Dr. Scott Glassman for his assistance with understanding and successfully completing the data analysis. This study relied heavily on the excellent work of Dr. Michelle Craske and Dr. David Barlow for developing the cognitive-behavioral treatment for panic disorder on which this study was largely based. They were also gracious enough to allow the use of their materials in this study. Dr. Brad Rosenfield in collaboration with Dr. J. Russell Ramsey, created the intervention protocol used in this study. If not for them, this would not have been possible. The assistance of Dr. Wendy Wild in ensuring protocol adherence is also greatly appreciated. Thanks to the staff and supervisors at WellSpan Health, including Dr. Allen Miller, Dr. Katrina Bakke-Friedland, and Dr. Michael Eshleman, for the support they provided. I would like to give special thanks to Gabriel Smith for her endless support and assistance throughout this journey. Finally, I would not be here today if not for the efforts and support of my parents, Jeffrey Daniels and Ann Daniels. PANIC TREATMENT iv Abstract Panic attacks, the key symptom of panic disorder and an associated feature of various anxiety disorders, are extremely distressing events that can negatively impact an individual’s mental health, physical health, and quality of life. This study validated a brief treatment for panic attacks, designed to reduce the frequency of panic attacks after the first session, in an outpatient clinical population. One participant was recruited to participate in this single case experimental ABA design with follow-up, where a reversal was not expected, due to the maintenance of positive effects. The treatment included both cognitive and behavioral techniques. The results were analyzed using simulation modeling analysis, as well as visual analysis. This treatment produced clinically significant effects by reducing the frequency and severity of panic attacks, reducing symptoms of anxiety and panic, decreasing the frequency of cognitive distortions, and increasing the level of functioning. Additionally, these gains were maintained at a 3- month follow-up. It is hoped that this intervention can help clinicians treat panic disorder and improve their effectiveness and efficiency by reducing the time needed to significantly decrease panic attacks. It is also hoped that this intervention might be expanded for use with other panic-related anxiety disorders. Finally, it is possible that this study will encourage efforts toward briefer treatments for other disorders.
