BACKGROUND INFO

											*Purpose*
This script implements a computerized version of the Scale of Suicide Ideation (SSI) as described in:

Beck, AT, Kovacs, M. & Weissman, A. (1979). Assessment of Suicidal Intention: The Scale for Suicide Ideation.
Journal of Consulting and Clinical Psychology, 47, 43-352.

											  *Task*
The SSI is a 19-item instrument to assess suicidal intentions. Each question has 3 answer choices.
Clinician fills out the survey based on a semi-structured interview.


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

(1) Raw data file: 'SSI.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 the participant spent on the surveypage with this particular question (in ms)
									(the last time this particular surveypage was visited)


(2) Summary data file: 'SSI_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)
/SSI_total:						sum of all response scores (0-38: the answer choice suggesting the least suicide intentions is scored as 0)


QUESTIONNAIRE SET-UP
* 19 questions with 3 answer choices each (the answer choice suggesting the least suicide intentions
is scored as 0); question 13 has 4 answer choices (but 2 are weighted the same)
* a SSI_total score is determined based on the sum of all individual scores
