Study Specific Coding (depreciated as of December 2019)

The NKI-RS data used to use the following coding convention to differentiate between data acquisition sessions from different studies:

Code (COINS) Code (NITRC/AWS) Description
Discoverysci DS Cross-Sectional Lifespan Connectomics Study
Long_child CLG Longitudinal Developmental Connectomics
Neurofeedbac NFB Real-Time Neurofeedback
LNG_ADULTFIT ALG Adult Longitudinal Study

Visit Codes

Code (COINS) Code (NITRC/AWS) Description
V1 1 The code for the first day of testing when we had two days of testing for our core battery
V2 2 The code for the second day of testing when we had two days of testing for our core battery
VA A The code for the one day of testing when we shifted from two days of data collection to one day for our core battery
VA_ALG A The code for the one day of testing (adult longitudinal fitness study), same as VA just with ALG because needed for data entry
V2REP 2R The participant has a baseline cross-sectional visit (V2) and then came back some period of time later and repeated (REP) the visit (V2) – we coded those visits (V2REP)
VA-REP AR The participant has a baseline cross-sectional visit (VA) and then came back some period of time later and repeated (REP) the visit (VA) – we coded those visits (VA-REP)
V4 4 Longitudinal Developmental Connectomics 12-15 month follow-up appointment
V5 5 Longitudinal Developmental Connectomics 24-30 month follow-up appointment

Note that in the real-time neurofeedback study, ‘R’ signifies a re-visit, while in the longitudinal developmental connectomics study, it represents a re-test.
