I concur with Eric....one of your first stops should be the Roman Catholic
religion.
Although dreadful, a large majority of the stereotypes you tend to hear about Italians, are true, that's the harsh reality of it all. (btw I am as guinea as they get)
I am assuming you are looking for the reality of it all to assist you with what topics to focus on and research, and not a sociology lesson on the perils of stereotyping? (because you
can figure out the cultural needs based on the stereotypes

).
What you
will need with Italians is patience, tolerance, and vigillance.

Expect to see all the
children, the next door neighbor the cousins, parents, nephews and nieces to visit at one time. Expect to take have to
take care of the
entire family unit along with the patient. Expect
mother's doting on their sons and vice versa. Expect to catch somebody sneaking
Pasta Fagioli in for Uncle Aldo
to eat with his
clear liquid diet before his bowel surgery. Don't forget 88 yr. old Aunt Theresa who has been in bed for two weeks with a Foley Catheter trying to get out of bed, to the commode because she just can't pee in that bedpan.
Another harsh truth is a large percentage of the men are helpless with zero pain tolerance and the
females are codependent. Italian males
tend to be abrasive and stoic translation: they are scared of the unknown. There is also the men who are total submissive to Mamma or their wife....usually just to Mamma. Think food, family, rituals, religion, and pride and you'll do just fine...Hope this helps.
