NCT01284959

Brief Summary

The main objective of this study was to assess subjective experiences related to secondary negative symptoms and cognitive performance in healthy volunteers in response to multiple doses of paliperidone ER and risperidone in a double-blind, placebo-controlled trial. Adverse events caused by these drugs were also evaluated.

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
