Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Clinical Global Impression- Improvement (CGI-I) | A positive clinical response will be determined by a rating of 1 or 2 (Very much/Much improved) on the Clinical Global Impression- Improvement (CGI-I) scale at the end of the blinded trial. | 8 Weeks | |
Secondary | Aberrant Behavior Checklist | Consists of 2 subscales; irritability (15 items) and hyperactivity/noncompliance (16 items). | 8 Weeks | |
Secondary | Self-Injury Trauma scale | Scores of 5 or greater were found to be indicative of borderline personality disorder. Part 1 is ranking based on the number of wounds 1=one would (common in a mild self-injurious behavior but rare in a severe case) 2=two or four wounds (common) and 3=five or more wounds (rare). Injury severity is scored on a subjective basis with labels such as "mild" "moderate" and "severe" accompanied by descriptions of the observed state of the anatomy. Part 3 is the Estimate of Current Risk. | 8 Weeks | |
Secondary | Modified Overt Aggression Scale | Four-part behavior rating scale used to evaluate and document the "frequency and severity" of aggressive episodes.[1] The rating scale is made up of four categories; verbal aggression, aggression against objects, aggression against self, and aggression against others | 8 Weeks |
