Changes in cognitive task performance, quality of life, anxiety, functional abilities and self-reported executive dysfunction as a function of stimulation condition.

Flanker interference scores, simple reaction time scores, and delay discounting are coded such that lower scores equate with better performance. GAD-7 = Generalized Anxiety Disorder scale, 7-item version; BDEFS=Berkeley Deficits in Executive Function Scale. For cognitive tests, baseline performance is estimated from performance on the cognitive task during the lead-in period averaged together with each pre-stimulation baseline score; for self-reported outcomes, baseline performance is estimated based on self-reported symptoms during the lead-in period only.
