Microstructural integrity of the uncinate fasciculus(UF) moderates the association between MASQ total and ERQ reappraisal scores. At relatively low UF microstructural integrity, the correlation between MASQ total and ERQ reappraisal scores was not significant (b = −1.238, p = .44). At intermediate (b = −4.55, p < .001) and relatively high UF microstructural integrity (b = −7.86, p < .001), there were significant negative correlations between MASQ total and ERQ reappraisal scores. Low, intermediate, and high UF values were defined as ≤ −1 SD, −1 SD <and < +1 SD, and ≥ +1 SD, respectively.
