BACKGROUND INFO

											*Purpose*
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


QUESTIONNAIRE SET-UP:
the script presents 11 surveypages that cover the 5 subcategories 
(Language - 5 questions,

Occupation & Orientation - 3 questions, 
Physical Independence - 16 questions, 
Mobility - 3 questions) described by Ritchie & Ledesert (1991)

A total score (expressions.BAS_score) is calculated at the end.


EDITABLE CODE:
check under EDITABLE CODE 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.

The parameters you can change are:
