Notes: The total sample size included 110 participants. However, six participants were excluded due to incidental findings (n = 2) and below-chance accuracy on the N-back task (n = 4), resulting in a final sample of 104 participants.
a
DERS questionnaire data were not completed for an additional n = 6 participants.
