Outcome Measures

Primary Outcomes (8)

  • Beck Anxiety Inventory (BAI)

    BAI total scores range from 0 to 63; higher total scores indicate more severe anxiety symptoms. Scores are clinically categorized as 0-7 (minimal anxiety) 8-15 (mild anxiety), 16-25 (moderate anxiety), and 26-63 (severe anxiety). The BAI and HAM-A are mildly correlated. BAI will be treated as normally distributed allowing parametric statistical methods to be used. Baseline BAI will be obtained.

  • Beck Anxiety Inventory (BAI)

    BAI total scores range from 0 to 63; higher total scores indicate more severe anxiety symptoms. Scores are clinically categorized as 0-7 (minimal anxiety) 8-15 (mild anxiety), 16-25 (moderate anxiety), and 26-63 (severe anxiety). The BAI and HAM-A are mildly correlated. BAI will be treated as normally distributed allowing parametric statistical methods to be used. BAI will be obtained.

    Visit 8 (Week 10)

  • Hamilton Anxiety Rating Scale (HAM-A)

    HAM-A total scores range from 0 to 56. Scores are clinically categorized as 17 or less (mild anxiety), 18-24 (moderate anxiety), and 25-30 (severe anxiety). HAM-A will be treated as normally distributed allowing parametric statistical methods to be used. Baseline HAM-A will be obtained.

  • Heart Rate Variability (HRV)

    Heart Rate Variability (HRV) time domain measures estimate the statistical variability of interbeat intervals. HRV will be obtained using the First Beat Bodyguard 2. Subjects will have the device placed according to the manufacturer's instructions on the torso. HRV will be captured for 2 minutes in a seated position, then 2 minutes in a standing position, then 2 minutes in a seated position. HRV, and vagal efficiency will be calculated using this data. Subjects will be instructed not to consume caffeine, alcohol or nicotine containing products within 12 hours of HRV data collection. Subjects will be told not to take anti-cholinergic medications (ex: antihistamines), central nervous system depressants or central nervous system stimulant medications within 24 hours of HRV measurement. (Based on literature review, alcohol, caffeine and nicotine are excreted completely within 12 hours and the majority of medications listed are excreted within 24-48 hours.)

  • Vagal Efficiency (VE)

    Vagal efficiency (VE) mean (SD) in a sample having a history of maltreatment were 61.7(19.5) and in a sample without a history of maltreatment were 69.6 (25.5). VE will be treated as normally distributed allowing parametric statistical methods to be used. Vagal efficiency is measured by the slope of the linear regression between heart rate and HRV. It represents the change in heart rate per unit increase/decrease in HRV. Clinically it is theorized that it measures the ability of the parasympathetic nervous system to adapt to dynamic changes in sympathetic tone.
