Internal and external cue's can activate these associations and reactivate the emotions. This way emotional memory could explain how adverse experiences increase mental health vulnerabilities. By playing into emotional memory, memory-focused treatments can have transdiagnostic advantages.

Many factors have been proposed to explain transdiagnostic benefits of ImRes, such as changing aspects of the memory, changing underlying beliefs about the self, others or the world, and playing into previously unmet needs. However, no study has yet tested if and how ImRes relates to changes in emotional memory characteristics and mental well-being, in a non-clinical population that experienced an adverse event. The current study investigated this question, by administering a single session of ImRes, and triangulated group-level findings with qualitative individual reports of how participants experienced ImRes and the brought about changes
