English to Polish Social Sciences Psychology Psychiatry

Hello,
I was wondering whether somebody could provide me with the translation of the term high expressed emotion (EE) in Polish. I'm translating an article about psychiatry from ENG into PL.

Here's the sentence:

"Leff and colleagues (1985) and Falloon and colleagues (1985) demonstrated the efficacy of modifying high expressed emotion (EE),"

Thanking you all in advance.
