Note. Chi-squared tests compare count-based demographic variables between sites and independent-samples t-tests compare means between sites for continuous variables of interest. Race: AA = African American, AI/AN = American Indian/Alaska Native, MR = More than one Race, U = Unknown/Not Reported. Reported values for depressive (DEP) and posttraumatic stress (PTS) symptoms are based on Trauma Symptom Checklist for Children (TSCC) raw scores. The Trauma History Profile (THP) data reflects raw scores. Default mode network connectivity for each of the Yeo-7 or 17 atlas parcellations is specified by year (i.e., Time 1, 2, or 3). MT = Medial Temporal Subsystem, Core = Core Subsystem, dmPFC = dorsal medial prefrontal cortex subsystem.
