VariableDescriptionNotes
2
ID (optional)
3
LifetimeDxPTSD or control - lifetime
For cases without structured clinical interview, provide diagnosis from self-report and indicate, PCL, PSS, or DTS and cutoff used in separate columns
4
LifetimeSxSeverityProvide severity score - lifetime
5
CurrentDxPTSD or control - current
6
CurrentSxSeverityProvide severity score - current
7
DxScaleProvide source for Dx and SxSeverity
8
ChildTraumaExposure
Quantify as 0=no childhood trauma, 1=one type of trauma (e.g. physical abuse only), 2=two or more types of trauma, NA= not assessed
if child trauma is not assessed, indicate NA for next 2 columns.
9
ChildTraumaScaleIndicate source such as CTQ, TLEQ, etc.
10
AgeofChildTraumaExposure
If available, indicate the age in years of child trauma exposure. If there are multiple exposures, indicate the age of FIRST exposure.
If child trauma data are available but age of exposure is unknown indicate "UNK". Leave blank if childtraumaexposure=0
11
AdultTraumaExposureProvide adult trauma exposure score (continuous)
12
AdultTraumaScaleIndicate source of adult trauma such as TLEQ, CES, etc.
13
AdultTrauma_Type
indicate the type of adult trauma exposure if known. If unknown, indicate "unknown". If there were multiple exposures, indicate "multiple"
We will organize responses into distinct types of trauma exposure categories (e.g., sexual assualt) once we have an idea of the range responses
14
TBIDid participant have a TBI? (1=yes, 0=no, NA=Not assessed)if TBI not assessed, indicate NA for next 3 columns. If TBI= 0, leave next 3 columns blank
15
NumTBINumber of TBIs sustained, or UNK if unknown
16
TBItype
Please indicate type of TBI, if known (1=blast, 2= impact, 3=penetrating, 4=accerlation/deceleration, 5=multiple, 6=unknown)
17
TBIseveritymild=1, moderate=2, severe=3, UNK
18
TBI_TimeSinceInjuryTime between TBI and scan, or UNK if unknownPlease use the following ranges: 0-2 months, 2-6 months, 6-18 months, 18 months-3 years, 3-10 years, >10 years
19
PsychotropicMedicationIndicate if participant was on psychotropic medication at the time of scan or NA if not assessedif psychotropic medication use was not assessed, skip next column
20
PsychotropicMed_TypeOptions are: antidep, antianx, antipsych, mood stabilizer, stimulants, none, UNK
21
AlcoholUseProvide score (0=none, 1=abuse, 2=dependence)
22
Alcohol scaleIndicate source
23
DepressionScoreProvide score (0=none, 1=current depression)
24
Depression_ScaleIndicate source
25
AgeAge in years at time of MRI scan
26
Sex1=male (M), 0=female (F)
27
Race
Indicate self-reported race (1) European (2) African (3) African American (4) Hispanic (5) Native American (6) East Asian (7) South Asian
28
SiteIDIf your sample was collected at multiple sites, list the siteID that differentiates which scan was collected whereMost samples will put NA here
29
ScannerManfIndicate scanner manufacturer
30
FieldStrengthIndicate field strength (1.5T, 3T, etc)
31
VoxelSizeIndicate voxel size of MRI acquisition
32
HippocampalSubfield_VLs_L
ENIGMA Hippocampal Subfield ROI volume averages - left hemisphere
33
HippocampalSubfield_VLs_R
ENIGMA Hippocampal Subfield ROI volume averages - right hemisphere
