This script implements the revised Michigan Alcohol Screening Test (MAST) with 22* YES/NO questions for a
self-assessment of social and vocational issues related to heavy drinking:
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.
*Note: by default, this script asks for additional information in regard to question 22 (-> textbox.q23)
Questionnaire with 22 binary yes-no questions.
DATA FILE INFORMATION:
The default data stored in the data files are:
(1) Raw data file: 'revMAST22.iqdat' (a separate file for each participant)
The raw questionnaire data are saved under "revMAST22.iqdat"
numeric scores are saved in values.q1-values.q23 in revMAST22_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: 'revMAST22_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)
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.
