As an example, PED-t has been proven to carry out comparably to CBT in enhancing psychosocial outcomes and lowering binge consuming, making it a viable various when CBT isn’t possible.
Some modern approaches, such because the Id Intervention Program (IIP) and repetitive transcranial magnetic stimulation (rTMS), have additionally been explored, though with blended outcomes. Notably, IIP has demonstrated a rise in optimistic self-schemas, although additional analysis is required to determine its long-term efficacy.
Whereas CBT stays the gold commonplace, different strategies, together with guided self-help (GSH) and transcranial Direct Present Stimulation (tDCS), provide promising alternate options, significantly when CBT isn’t possible or enough by itself.
