Registered outcomes 4
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Differences in change in frontal-striatal functional connectivity | Change between baseline and post-intervention (3 week) follow-up | Participants will complete MRI sessions on a 3T scanner located in the Center for Magnetic Resonance Research (CMRR) at the University of Minnesota. Participants will undergo resting-state MRI over a 12-minute scan in order to gather resting state functional connectivity (RSFC). Hierarchical linear models will examine differences in change in target engagement (frontal-striatal RSFC) between active and sham tDCS conditions. | ClinicalTrials.gov |
| Primary | Change in Trail Making Test (TMT) score | Change between baseline and post-intervention (3 week) follow-up; 1 and 2 months following intervention | The TMT is a neuropsychological test of visual attention and task switching. The test consists of two parts in which the participant is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. The test can provide information about visual search speed, scanning, speed of processing, mental flexibility and executive functioning. | ClinicalTrials.gov |
| Primary | Change in Stroop Color-Word Test (SCWT) score | Change between baseline and post-intervention (3 week) follow-up; 1 and 2 months following intervention | The SCWT is a neuropsychological test of the ability to inhibit cognitive interference which occurs when the processing of a stimulus feature affects the simultaneous processing of another attribute of the same stimulus. | ClinicalTrials.gov |
| Primary | Change in binge drinking days per week as measured using the Timeline Followback questionnaire | Change between baseline and post-intervention (3 week) follow-up; 1 and 2 months following intervention | The TLFB questionnaire measures substance use disorder severity. The questionnaire asks the participant about substance use in the past 30 days. The participant reports on a binary scale as to whether or not they have used a given substance. Binge drinking is defined as men consuming 5 or more drinks or women consuming 4 or more drinks in about 2 hours. | ClinicalTrials.gov |
