Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Positive and Negative Symptoms Scale, Excitatory Subscale (PANSS-EC) Score (Time Frame: 3 Weeks)
Time Frame: baseline and 3 weeks
|
PANSS-EC score change was to be measured by calculating the difference between baseline score and 3 week's score.
The PANSS-EC consists of 5 items (Poor IMpulse Control, Tension, Hostility, Uncooperativeness, and Excitement), each with associated descriptors.
Each descriptor is rated on a 7 point scale from 1 = (absence of any symptom) to 7 = (extremely severe symptoms).

Measure Description |
Time Frame |
|---|---|---|
|
Change From Baseline in Clinical Global Impression, Severity Scale (CGI-S) and in Absolute Clinical Global Impression, Improvement Scale (CGI-I) (Performed 4 Times/ 3 Weeks)
Time Frame: baseline and 3 weeks
|
The CGI change was to be measured by calculating the difference between baseline score and 3 week's score.
CGI-S Score of 1 = no illness to score of 7 = extremely ill.
CGI-I Score of 1 =very much improved since the initiation of treatment to 7=very much worse since the initiation of treatment

|
Change From Baseline in Overt Aggression Scale (OAS) (Performed 6 Times/ 3 Weeks)
Time Frame: baseline and 3 weeks
|
The Overt Agression Scale (OAS) change was to be measured by calculating the difference between baseline score and 3 week's score.
Score between 1 and 16 verbal aggression (OAS 1, score 1-4), physical aggression against objects (OAS 2, score 5-8), physical aggression against self (OAS 3, score 9-11) and physical aggression against other people (OAS 4, score 12-16).

baseline and 3 weeks
|
|
Change From Baseline in Total Positive and Negative Symptoms Scale (PANSS Score) (Performed 5 Times/ 3 Weeks)
Time Frame: baseline and 3 weeks
|
PANSS score change was to be measured by calculating the difference between baseline score and 3 week's score.
The PANSS consists of 7 positive and 11 negative items each with associated descriptors.
Each descriptor is rated on a 7 point scale from 1=(absence of any symptom) to 7=(extremely severe symptoms).
