This script implements a computerized version of the  Self-Injurious Thoughts and Behaviors Interview (SITBI)

SITBI is an interview-based measure to uniformly assess the presence, frequency, and characteristics of 
(a) suicidal ideation, (b) suicide plans,  (c) suicide gestures, (d) suicide attempts, and (e) NSSI.
