Dr. Callaghan's research spans three primary domains: Interpersonal Behavior Therapy (IBT), Functional Analytic Psychotherapy (FAP), and the development of idiographic assessment tools like the Functional Idiographic Assessment Template (FIAT) system. His publications explore behavioral narratology, psychopathology assessment, and mindfulness-based interventions, often addressing how contextual-behavioral principles can refine therapeutic practices and diagnostic frameworks.

Recent scholarship highlights his integration of FAP with third-wave therapies, the psychometric validation of the FIAT-Q questionnaire, and applications of behavioral analysis to body image disturbance, diabetes self-management, and trauma recovery. Dr. Callaghan's methodological contributions include coding systems (e.g., FAPRS) and therapist skill assessment tools (FASIT), underscoring his commitment to advancing behavioral psychotherapy through empirical rigor.
