Outcome Measures

Primary Outcomes (2)

  • Change in Percent of Heavy Drinking Days Per Week as Assessed by the Timeline Followback (TFLB)

    The TLFB interview, using a calendar, asks participants to report the prior week's frequency of alcohol use on each day of the week.

    Baseline to Week 8

  • Change in TBI Symptoms as Assessed by the Neurobehavioral Symptom Inventory (NSI)

    Participants indicate the extent to which each of the 22 symptoms has disturbed them in the previous 2 weeks on a 5-item scale (0-none to 4-severe). The NSI total score is the sum of severity ratings of the symptoms. The scores are summed to yield a total score ranging from 0 to 88, where the higher the point value, the greater (more severe) the symptoms

    Baseline to Week 8

Other Outcomes (1)
