    Primary Outcomes
    • The C-SSRS is a semi-structured interview designed to assess the severity and intensity of suicidal ideation, suicidal behavior, and non-suicidal self injurious behavior over a specified time period. The measurement of suicidal ideation is based on five "yes" or "no" questions with accompanying descriptions arranged in order of increasing severity.

    Secondary Outcomes
    • The MADRS is a clinician rated scale measuring depression severity, consisting of 10 items, each scored from 0 (normal) to 6 (severe), for a total possible score of 60; higher scores denote greater severity.

    • The CGI is a 3-item observer-rated scale that measures illness severity, global improvement or change and therapeutic response.

    • The CGI is a 3-item observer-rated scale that measures illness severity, global improvement or change and therapeutic response.

    • The CHRT-SR is a 12-item self-report measure that systematically assesses both suicidal thinking and associated thoughts that might indicate the propensity for suicidal acts.
