Is it necessary to use Cronbach's alpha for a checklist?

#1
The checklist in question is the Life Events Checklist (LEC) and I am using 7 questions from the checklist. I re-coded the answers, to 0= no experienced and 1= experienced.
Is there another way to test the reliability of a checklist? I have not seen many articles reporting alpha for the LEC.

What do they usually do then?
