Experimental: Risperidone
Subjects weighing less than 20 kilogram (kg) received risperidone 0.25 milligram per day (mg/day) up to Day 4. On Day 4, dose was titrated in increments of 0.25 mg/day (up to a daily dose of 1.0 mg) at the regular study visit thereafter till Week 8. Subjects weighing greater than or equal to (>=) 20 kg received risperidone 0.5 mg/day up to Day 4. On Day 4, dose was titrated in increments of 0.5 mg per day (up to a daily dose of 2.5 mg) at the regular visit thereafter till Week 8.
The maximum daily dose for subjects weighing >= 45 kg was 3.0 mg.
For subjects weighing >=45 kg, the maximum daily dose was 3.0 mg.

Measure Description |
Time Frame |
|---|---|---|
|
The change from baseline in the Aberrant Behavior Checklist-Japanese Version (ABC-J) Irritability Subscale scores
Time Frame: Baseline, Week 8
|
The ABC-J Irritability subscale consists of 15 items.
Each item scores range from 0 to 3: 0 = No problem, 1 = Mild aberrant behavior, 2 = Moderate aberrant behavior, and 3 = Severe aberrant behavior.
Higher scores represent worse condition.

|
The changes from baseline in the subscale scores of Aberrant Behavior Checklist-Japanese Version (ABC-J) at each evaluation of the double-blind phase
Time Frame: Baseline, Week 2, Week 4, Week 6
|
The ABC-J consists of 58 items divided into 5 subscales: Irritability, Lethargy and Social withdrawal, Stereotypic behavior, Hyperactivity/Noncompliance, and Inappropriate speech.
Each item scores range from 0 to 3: 0 = No problem, 1 = Mild aberrant behavior, 2 = Moderate aberrant behavior, and 3 = Severe aberrant behavior.
Higher scores represent worse condition.

The changes from baseline in scores of the Clinical Global Impression - Severity (CGI-S) at each evaluation time point of the double-blind phase
Time Frame: Baseline, Week 1, Week 2, Week 3, Week 4, Week 6, Week 8
|
The CGI-S rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a patient.
A rating of 1 is equivalent to "Normal, not at all ill" and a rating of 7 is equivalent to "Among the most extremely ill patients".
Higher scores indicate worsening.

The changes from baseline in scores of the Children's Global Assessment Scale (C-GAS) at each evaluation time point of the double-blind phase and open-label-phase
Time Frame: Baseline, Week 4, Week 8
|
The C-GAS rates the patient's general psychological and social functioning on scores ranging from 1 through 100.
Lower scores (range 1-10) mean that the patient needs constant supervision; higher scores (range 91-100) mean that the patient has a superior functioning in all areas.
