Transdiagnostic formulations can inform intervention and academic training programs: Commentary on Caspi et al. (2026).

Caspi et al. (see record 2026-80066-001) present intergenerational and developmental evidence demonstrating that psychopathology is fundamentally transdiagnostic, reflecting a general liability for mental disorder (p). We extend their argument by emphasizing how transdiagnostic psychotherapy models and training frameworks can actualize this concept in clinical practice. Using dialectical behavior therapy as an exemplar, we illustrate how targeting shared mechanisms, such as emotion dysregulation, can reduce psychopathology across diagnoses and generations. Finally, we call for clinical training programs to adopt curricula centered on transdiagnostic science to align the next generation of clinicians with the empirical realities of p and developmental psychopathology.
