A clinician-administered behavior rating scale measuring four types of aggressive behavior that will be assessed at all 9 visits. The subsets range on a scale from 0-4 with 0 indicating no aggression present. This scale tracks changes in level of aggression over time. The total weighted sum of the sections of the scale is recorded. Higher total scores indicate higher aggression levels.

A clinician-administered, 11 item scale that assesses manic symptoms at baseline and over time. Higher total scores indicate higher severity of manic symptoms. This scale is used to rate the severity of manic abnormality in the patient. Subsets of the scale range from 0-4 with 0 indicating no severity. This scale will be assessed at all visits.

A self-report scale assessing Borderline Personality severity that will be assessed at all visits.This scale is assessing severity and change in BPD symptoms. This is a 9-item scale measuring severity of different aspects of Borderline Personality Disorder, with each item rated on a 0-4 scale, 0=no symptoms, 4=severe symptoms. Total scores range from 0-36.

A self rated scale used to measure severity and change. The first 12 items of the scale are on a scale from 1-5, with 5 meaning that the item caused extreme distress, severe difficulties in relationships, and/or kept them from getting things done. The lowest rating (1) means it caused little or no problems. Items 13-15 (positive behaviors) are rated according to frequency. Completed at every visit.

A self-report assessment of impulsivity that will be assessed at baseline and visit 8. The BIS is composed of 30 items describing common impulsive or non-impulsive (for reverse scored items) behaviors and preferences. Items are scored on a 4-point scale: (Rarely/Never = 1, Occasionally = 2, Often = 3, Almost Always/Always = 4). These scores are summed to produce an overall impulsivity score ranging from 30 (not impulsive) to 120 (extremely impulsive).

An instrument that helps evaluate a broad range of psychological problems and symptoms of Borderline Personality Disorder psychopathology. This will be assessed at baseline and visit 8.The 115 items are rated by using a 5-step Likert scale (0=not at all, 4=very strong) and provide a global picture of borderline psychopathology. Global scores of borderline psychopathology are calculated by summing 12 items and range from 0-48. Higher scores indicate more severe symptoms of Borderline Personality Disorder.

A clinician-administered assessment of depression that will be assessed at all study visits (Visits 1-8). Higher total scores indicate higher levels of depression (up to 52), while a score of 0 would indicate no depressive symptoms.

A short-structured interview that assesses comorbid psychiatric disorders according to the DSM 5 criteria. This assessment will be done during the baseline visit.

Subjects will complete the SDS at all visits. The change in scores from baseline to study completion will be assessed. The scale itself assesses the level of disability from borderline personality disorder (or target disorder) with higher scores indicating a more debilitating disorder. Scores range from 0-30.

A self-report assessment of patient perceived quality of life that will be assessed at baseline and visit 8. Higher scores indicate a higher quality of life, whereas lower scores indicate a lower quality of life. Participants are asked to rate the importance of each domain on a 3-point scale ranging from 1=not important to 3=very important, and to rate how satisfied they are with that domain on a 6-point scale, ranging from -3=very dissatisfied to +3=very satisfied. In scoring, importance ratings are multiplied by satisfaction ratings to produce weighted satisfaction scores for each of the 16 domains. Weighted satisfaction scores are summed and divided by the number of domains that were rated as important or very important to produce a raw score, which is then converted to a t-score, which provides a proxy measurement for perceived quality of life. T-scores range from very low perceived quality of life (0-36) to high perceived quality of life (58-77).

A self-report scale measuring suicidality. Subjects will complete the scale at all visits. Subjects are asked about suicidal thoughts. If answers are no, rater can proceed to "suicidal behavior" section where subject is asked about any non-suicidal self injurious behavior. If yes, subject is asked about intensity of ideations. In the event of serious threat to themselves, the subject will be escorted to the emergency room. Total score indicates severity of suicidal ideation and behavior, with lower scores representing lower levels of suicidality and higher scores representing higher levels of suicidality. A score of 0 would reflect no suicidality present, whereas a maximum score of 5 would reflect active suicidal ideation with intent to act.
