BACKGROUND INFO

											*Purpose*
This script implements the Insomnia Severity Index (ISI) to assess Insomnia as described in:

Bastien, C.H., Vallières A., & Morin, C.M. (2001). Validation of the Insomnia Severity Index as a clinical outcome 
measure for insomnia research. Sleep Medicine, 2, 297-307.


										  *OVERVIEW*
This script offers the 7 questions of the Insomnia Severity Index on a single surveypage.
A demographic surveypage at the beginning (by default: not run) as well as a feedback page at the end (by default: run)
are optional and controlled via Editable Parameters.


DATA FILE INFORMATION: 
The default data stored in the data files are:

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

date, time, subject:			date and time script was run with the current subjectnumber 
build:							version of Inquisit
xxxx.response:					response to a particular question (here in numbers)
xxxx.latency:					latency of clicking "next" the last time the page was visited


(2) Summary data file: 'InsomniaSeverityIndex_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)

trialcode: 						the name and number of the currently recorded trial
									(Note: not all trials that are run might record data) 
xxxx.response:					response to a particular question (here: demographics)
/ISI_totalscore:				the participant's total ISI score


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.

The parameters you can change are:

/skipdemographics:							false = script does collect demographic data 
											true = script does NOT collect demographic data (default)
/skipfeedback:								false = script does provide feedback to participants (default)
											true = script does NOT provide feedback to participants
											Note: to customize feedback go to EDITABLE CODE -> Editable Stimuli
