DATA FILE INFORMATION
___________________________________________________________________________________________________________________
The default data stored in the data files are:
(1) Raw data file: 'PCL_C.iqdat'
date, time: date and time script was run with the current group/subjectnumber
subject, group, session: with the current subject/groupnumber/session id
build: the Inquisit build
q*_response: response given (in assigned values 1-5, no reverse coding required)
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: 'pcl_c_summary.iqdat' (Inquisit Lab: one data file per participant)
computer.platform: the platform the script was run on (win/mac/ios/android)
script.startdate: date script was run
script.starttime: time script was started
script.subjectid: assigned subject id number
script.groupid: assigned group id number
script.sessionid: assigned session id number
script.elapsedtime: time it took to run script (in ms); measured from onset to offset of script
script.completed: 0 = script was not completed (prematurely aborted);
1 = script was completed (all conditions run)
Scoring:for more info, see: https://www.ptsd.va.gov/professional/assessment/documents/PCL-5_Standard.pdf
expressions.totalSeverityScore: the sum of all individual questions (Range: 17 - 85)
a score of 44 is considered to be PTSD positive in general population
values.DSMIV_criteria: DSMIV_criteria = 1 (responses reached DSM IV criteria for PTSD)
=> positive criteriaB, positive criteriaC, positive criteriaD
DSMIV_criteria = 0 => the responses did not reach DSM IV criteria for PTSD
values.criteriaB: 1 (positive for DSM IV criteria B for PTSD):
At least one B-item was 'positively' rated (= 3 or above) (B-items: question 1-5)
0 = negative for DSM IV criteria B for PTSD
values.criteriaC: 1 (positive for DSM IV criteria C for PTSD):
At least three C-item were 'positively' rated (= 3 or above) (C-items: question 6-12)
0 = negative for DSM IV criteria C for PTSD
values.criteriaD: 1 (positive for DSM IV criteria D for PTSD):
At least two D-items were 'positively' rated (= 3 or above) (D-items: question 13-17)
0 = negative for DSM IV criteria D for PTSD
for each individual question (values.q1-values.q17), the raw response score (1-5) was binary coded as
1 = the response was 3 or above (participant chose at least 'moderately' for the individual question) => positive
0 = the response was 1 or 2 => negative
