BACKGROUND INFO 	
___________________________________________________________________________________________________________________	
This script implements the Short Michigan Alcohol Screening Test (SMAST) with 13 YES/NO questions for a 
self-assessment of social and vocational issues related to heavy drinking as published in:

Crews, T.M., & Sher, K.J. (1992). Using adapted short MASTs for assessing parental
alcoholism: Reliability and validity. Alcoholism: Clinical and Experimental Research
16, 576-584.

Note: the items published in the article are specific to alcohol abuse of a parent; the items
used in this script refer to oneself instead and were taken from:

http://www.sh.lsuhsc.edu/fammed/outpatientmanual/Short%20MAST%2013.htm


The original MAST 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. (-> see script MAST.iqx)

The default data stored in the data files are:

(1) Raw data file: 'smast.iqdat' (a separate file for each participant)

The raw questionnaire data are saved under "SMAST.iqdat"
numeric scores are saved in values.q1-values.q23 in SMAST_summary.iqdat

date, time:						date and time script was run with the current group/subjectnumber 
subject, group, session:	  		 with the current subject/groupnumber/session id
build:							the Inquisit build 

q*_response:						response given (in assigned values)
									Scale:
									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)
								
								
(2) Summary data file: 'smast_summary*.iqdat' (a separate file for each participant)

computer.platform:			the platform the script was run on (win/mac/ios/android)
script.startdate:				date script was run
script.starttime:				time script was started
script.subjectid:				assigned subject id number
script.groupid:				assigned group id number
script.sessionid:				assigned session id number
script.elapsedtime:			time it took to run script (in ms); measured from onset to offset of script
script.completed:				0 = script was not completed (prematurely aborted); 
							1 = script was completed (all conditions run)
