Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Yale Brown Obsessive Compulsive Scale (YBOCS) | The primary outcome measure will be the change from baseline using the Yale Brown Obsessive Compulsive Scale (YBOCS). The YBOCS is a 10-item scale that assesses OCD symptoms during the last seven days. The first five items comprise the urge/thought subscale and items 6-10 comprise the behavior subscale. | Baseline to Week 2 | |
Primary | NIMH Symptom Severity Scale (for TTM or Skin Picking) | The primary efficacy measure will be the change in hair pulling or skin picking frequency and urges to pull hair or pick skin for the past week as indicated by change in total score. The entire study lasts 10 weeks. Every two weeks subjects will take the NIMH-TSS. The change in scores from baseline to after 10 weeks will be assessed. The scale itself assesses severity of trichotillomania symptoms. The NIMH-TSS score ranges from 0 to 20, with 0 being no symptoms and 20 being the most severe. | Baseline to Week 2 | |
Primary | The Hoarding Rating Scale (HRS) | The Hoarding Rating Scale is a brief, clinician rated 5-item scale This tool includes 5 questions about clutter, difficulty discarding, excessive acquisition, and the resulting distress and impairment caused by hoarding. Initial studies suggest that a score of 14 or higher on the HRS indicates a probable hoarding problem/Hoarding Disorder diagnosis. | Baseline to Week 2 | |
Primary | Yale Global Tic Severity Scale (YGTSS) | The Yale Global Tic Severity Scale is a semi-structured clinical interview and currently the gold standard for assessing the severity of tics in children and adults. The YGTSS enables evaluations of number, frequency, intensity, complexity, and interference of motor and phonic tics, covering the past week. Each domain is scored on a 6-point scale (range 0-5) with a separate rating for "overall impairment" regarding the subject's daily life and activities (4). Five sum scores can be created: the total motor tic score (range 0-25), the total phonic tic score (range 0-25), the total tic score (TTS; sum of the total motor tic score plus the total phonic tic score), the overall impairment rating (one item; range 0-50), and the global severity score (GSS; sum of the TTS plus the overall impairment rating, range 0-100). Higher scores reflect worse severity and worse impairment. | Baseline to Week 2 | |
Secondary | Clinical Global Impressions- Improvement Scale (CGI-I) | The entire study for the subject will last 8 weeks. Every week the subject will complete the CGI. The change in scores from baseline to after 8 weeks will be assessed. The scale itself assesses overall disorder severity on a scale from 1 to 7 with 1 being "not at all" and 7 being "among the most severe cases" | Baseline to Week 2 | |
Secondary | Hamilton Depression Rating Scale (HAM-D) | A clinician-administered assessment of depression that will be assessed at all study visits. Higher total scores indicate higher levels of depression, while a score of 0 would indicate no depressive symptoms. | Baseline to Week 2 | |
Secondary | Hamilton Anxiety Rating Scale (HAM-A) | A clinician-administered assessment of anxiety that will be assessed at all study visits. Changes in scores from baseline to final visit will be assessed. Higher scores indicate higher levels of anxiety, with 0 being no symptoms of anxiety. | Baseline to Week 2 | |
Secondary | Sheehan Disability Scale (SDS) | 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 target disorder with higher scores indicating a more debilitating disorder. | Baseline to Week 2 | |
Secondary | Quality of Life Inventory (QOLI) | A self-report assessment of patient perceived quality of life that will be assessed at baseline and week 8. Higher scores indicate a higher quality of life, whereas lower scores indicate a lower quality of life. | Baseline to Week 2 |
