One 9-minute session of TMS TBS delivered each morning, prior to commencement of their regularly scheduled daily therapy activities, for 5 days/week, for a total of four-weeks (20 sessions total).

On this computer task, participants are asked to respond to stimuli by either executing ("go" stimuli) or withholding a response ("no-go" stimuli). More "go" stimuli are presented than "no-go" stimuli to induce a prepotent response. Performance on the Go/No-Go task is measured by calculating the proportion of commission errors (i.e., false alarms, making a response to a "no-go" stimulus), omission errors (i.e., misses, failing to respond to a "go" stimulus), and the response times to "go" stimuli. Higher proportions of commission errors are indicative of an inability to inhibit a response, sometimes referred to as rapid-response impulsivity. (Donders, 1969)

On this computer task, participants are shown a balloon and told that each press of a button will increase the size of the balloon and reward them with a small, hypothetical monetary reward. However, after a variable number of pumps, the balloon will explode, causing them to lose all accumulated rewards on that trial. Participants can pump up the balloon as much as they want before moving onto the next trial. Performance on the BART is measured by calculating the average number of pumps on each balloon excluding balloons that exploded. A higher average number of pumps is associated with more impulsiveness. (BART; Lejuez et al., 2002)

On this 30-item questionnaire, participants use a 4-point Likert-type scale (1 = Rarely/Never, 4 = Almost Always/Always) to indicate how frequently statements like "I do things without thinking" and "I concentrate easily" apply to themselves. The BIS-11 total score is a summed score of all responses and can range from 30 to 120, with higher scores indicating higher levels of impulsiveness. There is also an option to calculate scores for three aspects of impulsiveness: attentional, motor, and nonplanning. These subscale scores are calculated by summing the number of associated items. The attentional impulsiveness subscale consists of 8 items, and total scores can range from 8 to 32; the other two subscale scores are 11 items each and scores can range from 11 to 44. (BIS-11; Patton et al., 1995)

On this 40-item questionnaire, participants are shown two choices, like "A. I prefer friends who are excitingly unpredictable or B. I prefer friends who are reliable and predictable," and asked to select the statement that most or best describes how they feel. One point is given for the more sensation-seeking choice. The SSS total score is the sum of all more sensation-seeking choices and can range from 0 to 40, with higher scores indicating more sensation-seeking. There is also an option to calculate scores for each of the four factors that make up sensation-seeking: [social and sexual] disinhibition, boredom susceptibility, thrill and adventure seeking, and experience seeking. Each of these scales is made up of 10 of the items and scores can range from 0 to 10. (SSS; Zuckerman et al., 1964)
