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.
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)
* 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
