BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements the revised Michigan Alcohol Screening Test (revMAST) with 22* YES/NO questions for a 
self-assessment of social and vocational issues related to heavy drinking:
http://www.ou.edu/cwtraining/assets/pdf/handouts/1009/revMAST.pdf

The original revMAST used 25 questions and a more elaborate scoring system. It was published by:
Selzer, M.L. (1971). The Michigan Alcoholism Screening Test: The quest for a new diagnostic instrument.
Am J Psychiatry, 127, 1653-1658.

*Note: by default, this script asks for additional information in regard to question 22 (-> textbox.q23)

subject, group, session:	  	with the current subject/groupnumber/session id
build:							the Inquisit build 

q*_response:					response given (in assigned values)
									Scale: 1 (yes = 'alcoholic response') - 0 (no)
									R = automatically reversed scored questions
									
q*_latency:					how much time (in ms) the participant spent on the surveypage with this particular 
								question (the last time this particular surveypage was visited)
