OVERVIEW
___________________________________________________________________________________________________________________
from https://cesd-r.com/about-cesdr/:
"from The 20 items in CESDR scale measure symptoms of depression in nine different groups as defined
by the American Psychiatric Association Diagnostic and Statistical Manual, fifth edition.
These symptom groups are shown below, with their associated scale question numbers to the right.
Sadness(Dysphoria): Question numbers 2,4, 6
Loss of Interest(Anhedonia): Question numbers 8, 10
Appetite: Question numbers 1, 18
Sleep: Question numbers 5, 11, 19
Thinking / concentration: Question numbers 3, 20
Guilt(Worthlessness): Question numbers 9, 17
Tired(fatigue): Question numbers 7, 16
Movement(Agitation): Question numbers 12, 13
Suicidal ideation: Question numbers 14, 15"
The questions are scored on a scale from 0 (not at all) - 4 (almost every day for 2 weeks)

DURATION

the default set-up of the script takes appr. 2 minutes to complete

DATA FILE INFORMATION
___________________________________________________________________________________________________________________
The default data stored in the data files are:
(1) Raw data file: 'cesd_r.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)
Scale: 0 (not at all) - 4 (almost every day for 2 weeks)
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: 'cesd_r_summary.iqdat' (Inquisit Lab: one data file per participant)
inquisit.version: Inquisit version run
computer.platform: the platform the script was run on (win/mac/ios/android)
startDate: date script was run
startTime: time script was started
subjectid: assigned subject id number
groupid: assigned group id number
sessionid: assigned session id number
elapsedTime: time it took to run script (in ms); measured from onset to offset of script
completed: 0 = script was not completed (prematurely aborted);
1 = script was completed (all conditions run)

//Determining Categories:
NoClinicalSignificance: true (1): Participants scored less than 16 in expressions.CESD_R_totalscore1
false (0): otherwise
Subthreshhold_Depression: true (1)= Participant scored at least 16 in expressions.CESD_R_totalscore1
but had 'false' (0) (did not qualify for) in expressions.PossibleMajorDepressiveEpisode
false (0)= otherwise
OR: "fullfills Criteria for a possible Major Depressive Episode"
PossibleMajorDepressiveEpisode: true (1) = Participant selected the most severe response ('nearly every day for the last 2 weeks')
to all Dysphoria and Anhedonia questions
as well as selected the most severe response ('nearly every day for the last 2 weeks')
Or second severe response ('5-7 days last week') in at least 2 other DSM symptom groups
false (0) = otherwise
ProbablyMajorDepressiveEpisode: true (1): Participant selected the most severe response ('nearly every day for the last 2 weeks')
to all Dysphoria and Anhedonia questions
as well as selected the most severe response ('nearly every day for the last 2 weeks')
Or second severe response ('5-7 days last week') in at least 3 other DSM symptom groups
false (0) = otherwise
MajorDepressiveEpisode: true (1): Participant selected the most severe response ('nearly every day for the last 2 weeks')
to all Dysphoria and Anhedonia questions
as well as selected the most severe response ('nearly every day for the last 2 weeks')
in at least 4 other DSM symptom groups
false (0) = otherwise
CESD_R_totalscore1: sum of responses to all 20 questions (on scale 0-4); Range: 0 - 80)
CESD_R_totalscore2: sum of responses to all 20 questions (on scale: 0, 1, 2, 3, 3); Range 0 - 60
Note: this total score scores the last response option ('nearly every day for the last 2 weeks')
with a 3 to make the totalscore comparable to the original CESD score
Dysphoria: sum of q2,4,6 (on scale 0-4), Range: 0-12
Anhedonia: sum of q8,10 (on scale 0-4), Range: 0-8
Appetite: sum of q1,18 (on scale 0-4), Range: 0-8
Sleep: sum of q5,11,19 (on scale 0-4), Range: 0-12
Concentration: sum of q3,20 (on scale 0-4), Range: 0-8
Guilt: sum of q9,17 (on scale 0-4), Range: 0-8
Tired: sum of q7,16 (on scale 0-4), Range: 0-8
Movement: sum of q12,13 (on scale 0-4), Range: 0-8
SuicidalIdeation: sum of q14,15 (on scale 0-4), Range: 0-8
//raw scores to all 20 questions (on scale 0-4)
