Test-retest reliability of longitudinal task-based fMRI: Implications for developmental studies

Abstract: Great advances have been made in functional Magnetic Resonance Imaging (fMRI) studies, including the use of longitudinal design to more accurately identify changes in brain development across childhood and adolescence. While longitudinal fMRI studies are necessary for our understanding of typical and atypical patterns of brain development, the variability observed in fMRI blood-oxygen-level dependent (BOLD) signal and its test-retest reliability in developing populations remain a concern. Here we review the cu… Show more

“…ICCs ranging between 0.08 and 0.33, although most being at least above .1 (e.g., Ordaz, Foran, Velanova, & Luna, 2013). Compared to fMRI ICCs, these values are comparable for neural activity in subcortical brain regions (Braams et al, 2015;Herting, Gautam, Chen, Mezher, & Vetter, 2017;Schreuders et al, 2018) and highlight that patterns were more consistent at the group than the individual level. One interpretation of low test-retest reliability (such as the ICC) is that there is a poor consistency of functional connectivity.…”

“…One interpretation of low test–retest reliability (such as the ICC) is that there is a poor consistency of functional connectivity. However, for studies with relatively longer delays between time points and younger populations, a low ICC may also reflect development over time (Herting et al, ). To distinguish which of these effects contributes most to these ICC results, future studies should further examine the test–retest reliability of RS scans in developmental populations, preferably also including shorter durations between scans.…”

“…Low ICCs for fMRI data seem to be no exception. Although Bennett and Miller () computed an average ICC of 0.50 across multiple fMRI reliability studies, ICCs varied substantially across ROIs and contrasts examined in individual studies (see also Herting et al, , for similar findings in developmental samples). In addition, poor ICCs were found in several earlier studies focusing on face processing that examined fMRI reliability (e.g., Lipp et al, ; Van der Bulk et al, ).…”

“…In earlier studies, fMRI test-retest reliability was investigated using various tasks and experimental designs (Bennett & Miller, 2010;Herting, Gautam, Chen, Mezher, & Vetter, 2017). Bennett and Miller (2010) computed an average intraclass correlation coefficient (ICC) of 0.50 across 13 earlier fMRI reliability studies, but report substantial variation across studies, with ICCs ranging from 0.16 to 0.88.…”

“…Furthermore, there are logistical and computational challenges such as head motion, task compliance and performance accuracy, image registration and multiple comparisons corrections, and a lack of normative data, which could introduce bias into statistical estimates and therefore result in spurious conclusions. Advanced methodological and computational approaches have improved the reliability of taskbased fMRI developmental studies (Herting, Gautam, Chen, Mezher, & Vetter, 2017), and have improved data quality (Grayson & Fair, 2017).…”
