BACKGROUND INFO

											*Purpose*
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)

											  *Task*
Questionnaire with 13 binary yes-no questions.



DATA FILE INFORMATION: 
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, group, subject:		date and time script was run with the current group/subjectnumber 
build:							the Inquisit build 

q*_response:					response given (in assigned values)								
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)

build:							Inquisit build
computer.platform:				the platform the script was run on
date, time, subject:			date and time script was run with the current subjectnumber 
script.elapsedtime:				time it took to run script (in ms)
completed:						0 = script was not completed (script aborted prematurely); 1 = script was completed (all conditions run)

Summarydata for each participant: file saves the scores for the subscales and totalscore as well as the 
number of missed items and the individual missed items (IF answering the questions is not required - by default it is)
(responses are reversed scored if appropriate)


SCORING
From the website: http://www.sh.lsuhsc.edu/fammed/outpatientmanual/Short%20MAST%2013.htm
"A "No" answer to question 1,4, and 5, and each "Yes" response to the other questions earn one point.
 Two points indicate a possible problem. Three points indicate a probable problem."

EDITABLE CODE:
check below for (relatively) easily editable parameters, stimuli, instructions etc. 
Keep in mind that you can use this script as a template and therefore always "mess" with the entire code to further customize your experiment.
