Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Hamilton Anxiety Rating Scale (HAM-A) | Week 6 | The HAM-A Scale is a clinician-rated scale measuring both psychic anxiety (mental agitation and psychological distress) and somatic anxiety (physical complaints related to anxiety). It is comprised of 14 items that are rated on a 5-point scale ranging from 0 = not present to 4 = very severe, disabling symptoms. The HAM-A total score ranges from 0 to 56 with a higher score indicating increased severity of anxiety symptoms. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Global Impression Scale-Severity (CGI-S) | Week 6 | The CGI-S is a clinician-rated scale to assess a patient's overall mental health. The scale ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill patients) |
