DOI: 10.1016/j.janxdis.2021.102457
Abstract: Considered a transdiagnostic process spanning across emotional disorders, self-absorption reflects self-focused processing that is excessive, sustained, and inflexible. Working memory capacity is critical for self-regulation, inclusive of mitigating perseverative thinking. Providing the first known examination… read more here.
