Dr. Glenn Callaghan received his PhD from University of Nevada and is a Full Professor of Psychology at San Jose State University (SJSU) as well as an Adjunct Professor at Palo Alto University. He has taught graduate and undergraduate coursework in psychopathology, clinical theory and application, clinical practicum, and psychopharmacology. He is Training Director of the Clinical Psychology graduate program and director of the Center for Innovative Assessment and Treatment at SJSU. His research covers Functional Analytic Psychotherapy (FAP; an interpersonal behavior therapy), Acceptance and Commitment Therapy (ACT) as well as the combination of the two (FACT), and clinical problems related to depression, body image disturbance, and personality disorders. He also has written empirical and theoretical articles on crisis negotiations, direct to consumer marketing, and evidence based practice strategies in cognitive behavioral therapy.

Dr. Callaghan’s primary research program has focused on investigating and improving the mechanism of clinical change in FAP, where he has developed one of the assessment systems used in FAP (the Functional Idiographic Assessment Template, or FIAT and FIAT-Q, now translated in 4 languages) as well as the process coding measure frequently used in FAP research (the Functional Analytic Psychotherapy Rating Scale, or FAPRS). He has provided workshops to students and professional audiences across the United States and in Australia and Europe. He is the author of multiple peer-reviewed articles and book chapters and has co-authored 2 books. When he is outside of academics, he is an avid guitar player and loves to spend time with his wife and young children exploring the outdoors and having grand adventures.
