Generalizability (G‐coefficients) and dependability (D‐coefficients) estimates of relative and absolute measurement reliability, respectively, for a multisite study design in which each subject is studied on one occasion at a site/scanner drawn randomly from the set of all available sites/scanners, and average within‐site (test–retest) intraclass correlations (ICCs), for maximum percent signal change in fMRI contrasts and regions of interest and for behavioral measures of emotion processing
