This script implements the Behavioural Assessment Scale as described in:
Ritchie, K. & Ledesert, B. (1991). The Measurement of Incapacity in the Severly Demented Elderly: The
Validation of a Behavioural Assessment Scale. International Journal of Geriatric Psychiatry, 6, 217-226.
The Behavioural Assessment Scale assesses the intellectual functioning and adaptive behaviors in
patients suffering from severe dementia.
DATA FILE INFORMATION:
The default data stored in the data files are:
(1) Raw data file: 'BAS.iqdat'
date, time, subject: date and time script was run with the current 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: 'BAS_summary*.iqdat' (a separate file for each participant)
script.startdate: date script was run
script.starttime: time script was started
script.subjectid: subject id number
script.groupid: group id number
script.elapsedtime: time it took to run script (in ms)
computer.platform: the platform the script was run on
/completed: 0 = script was not completed (prematurely aborted); 1 = script was completed (all conditions run)
/checkboxscore: stores the scoresum of all items presented as checkboxes
/radiobuttonscore: calculates subtotal scoresum from radiobutton items
/BAS_total: calculates the totalscore based on all items
the script presents 11 surveypages that cover the 5 subcategories
(Language - 5 questions,
