<p>Mindfulness and yoga, rooted in traditional practices, are used to treat generalized anxiety disorder either as stand-alone interventions or alongside psychotherapy. While these are related practices, few studies compare them in terms of the mechanisms of change or transdiagnostic processes they engage. Moreover, their application is often disconnected from the traditions they originate from, neglecting the coherence and context of their original systems. Anxiety disorder, focused on generalized anxiety disorder, was chosen to investigate these aspects through two research questions: 1. Does yoga utilize the same anxiety-related transdiagnostic processes as mindfulness does in the treatment of generalized anxiety disorder? 2. To what extent are yoga and mindfulness practices used in psychotherapy for generalized anxiety disorder in a way that is congruent with their tradition of origin? This narrative review identified a range of transdiagnostic processes that are related to mindfulness-based interventions, including affective, cognitive, behavioural, executive functions, and mindfulness-related processes. A more limited set of transdiagnostic processes has been connected to yoga interventions thus far, with mindfulness-related processes being the most documented. The integration of traditional teachings into the study of these mechanisms remains minimal (compassion, acceptance, etc.). This relevant research gap highlights the need to test models of change informed by Eastern psychodynamic frameworks. Revisiting existing research models to better align these interventions with their traditional origins could enhance their clinical utility, increasing coherence and improving their effectiveness in addressing specific disorders.</p>
