Brief Summary
The purpose of this study is to evaluate the efficacy and safety of long acting injectable microspheres of risperidone in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self), schizophreniform or schizoaffective disorders (disorders in which there is a loss of ego boundaries or a gross impairment in reality testing with delusions or prominent hallucinations).

Outcome Measures
Primary Outcomes (1)
Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Score at Week 26
The PANSS is a 30-item scale designed to assess various symptoms of schizophrenia including delusions, grandiosity, blunted affect, poor attention, and poor impulse control. The 30 symptoms are rated on a 7-point scale that ranges from 1 (absent) to 7 (extreme psychopathology). The PANSS total score consists of the sum of all 30 PANSS items and ranges from 30 to 210, higher scores indicate worsening. Change at Week 26 score is calculated as Baseline score minus Week 26 score.

Study Arms (1)
Risperidone
EXPERIMENTALRisperidone 25 milligram (mg) will be given as intramuscular injection for every 2 weeks up to 6 months. Participants with persistent symptoms and/or requiring higher doses of antipsychotics will be administered higher doses of risperidone. Doses will be adjusted as per Investigator's discretion.
Interventions
Risperidone 25 milligram (mg) will be given as intramuscular injection for every 2 weeks up to 6 months. Participants with persistent symptoms and/or requiring higher doses of antipsychotics will be administered higher doses of risperidone. Doses will be adjusted as per Investigator's discretion.
Eligibility Criteria
You may qualify if:
- Symptomatically stable participants defined as a) participants with treatment on outpatient and inpatient basis for at least 4 weeks before entering the study, and b) Positive and Negative Syndrome Scale (PANSS) Positive Subscale Score less than or equal to (\<= ) 3 (1-7), including conceptual disorganization, suspicion, hallucinatory conduct and delirium (state of violent mental agitation)
- Participants under antipsychotic treatment with extrapyramidal symptoms, persistent negative symptoms or lack of adherence defined as irregular administration of medication in the last 2 weeks
- Participants who have given their informed consent in writing, or at least, by their family member or personal representative
You may not qualify if:
- Participants taking first antipsychotic treatment in his/her life
- Pregnant or nursing women
- History of neuroleptic malignant syndrome (potentially fatal syndrome associated primarily with the use of antipsychotic drugs and clinical features include diffuse muscle rigidity, tremor, high fever) or current symptoms of tardive dyskinesia (a neurological disorder characterized by involuntary movements of the face and jaw)
- Participants with known intolerance or lack of response to risperidone

Limitations and Caveats
The planned sample size was not reached and a high dropout rate of participants was observed. Due to the high number of protocol violations, analysis was performed as intention-to-treat instead of per protocol as was planned.
