Outcome Measures
Primary Outcomes (1)
Assessment of Negative Symptoms and Neuroleptic Induced Deficit Syndromes by Objective Rating Scales
SANS(Scale for the Assessment of Negative Symptoms), NIDSS(Neuroleptic induced Deficit Syndrome Scale) In NIDSS, the average of number 1 to 5 is blunted affect, the average of number 16 to 20 is avolition, the average of number 6 to 15 is cognition, the average of all score is total. Minimum of NIDSS(avolition, blunted affect, cognition, total) is -3, maximum is +3.(subscale score and total) '+' is better outcome, '-' is worse outcome. Minimum of SANS-Global score for alogia and blunted affect is 0, Maximum of SANS-Global score for alogia and blunted affect is 5 The higher number is worse outcome. The zeros are measured and Calcuated value This outcome measure is reporting a change between baseline and 2hr after third medication.

Limitations and Caveats
The sample size was small, which presents higher risk of a type II error. The time of assessment after administering placebo or risperidone was noon to 2 PM, which may have contributed to the increased reports of sedation
