What researchers measure

Primary outcomes

  1. Cohen-Mansfield Agitation Inventory (CMAI) total score

    The CMAI is a reliable and validated, 29-item caregiver-rating questionnaire to assess agitated behavior in elderly patients. Each item is rated on a 7-point scale of frequency, from "never" (1) to "several times an hour" (7), with 1 being the "best" rating and 7 being the "worst" rating. The minimum possible CMAI total score is 29, and the maximum possible CMAI total score is 203.

    Time frame: Week 12

Secondary outcomes

  1. Clinical Global Impression-Severity (CGI-S) Score

    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)

    Time frame: Week 12
