  • Clinical Global Impressions (CGI) - Disease Severity Score [ Time Frame: Baseline and Week 2, 4, 8, 16, 24, 38 and 50 ] [ Designated as safety issue: No ]
    The CGI rating scale is a 7-point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. A rating of 1 indicates to "normal, not at all ill" and a rating of 7 indicates "among the most extremely ill participants". Higher scores indicate worsening.
  • Extrapyramidal Symptoms Rating Scale (ESRS) Total Score [ Time Frame: Baseline and Week 2, 4, 8, 16, 24 and 50 ] [ Designated as safety issue: Yes ]
    The ESRS is used to assess four types of drug-induced movement disorders administered as a questionnaire. Score range from 0 to 6 (0 is absent and 6 is extremely severe).
  • Drug Attitude Inventory (DAI-10) [ Time Frame: Screening, and Week 8, 24 and 50 ] [ Designated as safety issue: Yes ]
    The DAI-10 is a 10-item questionnaire to assess 1) subjective experience of drug and 2) attitudes and beliefs toward neuroleptics which may influence compliance in schizophrenia participants. It is the binary scale assessing the participant's subjective response. A 'compliant' response is scored as +1; a dysphoric response is scored as -1. A positive sum of items indicates a positive subjective response (SR); a negative sum of scores indicates a negative SR (non-compliant). The final score is the grand total of the positive and negative points. Total score ranges from (-) 10 to (+) 10, higher score indicates positive SR (compliant) and lower score indicates negative SR (non-compliant).
  • Short Form-36 (SF-36) - Quality of Life [ Time Frame: Baseline and Week 50 ] [ Designated as safety issue: No ]
    The SF-36 is a survey of participant health. It consists of eight scaled scores, which are the weighted sums of the questions in their section. The eight sections are: vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. Each item is scored on a 0-100 range so that the lowest and highest possible scores are set at 0 and 100, respectively. All items are scored so that a high score defines a more favorable health state.
  • Personal and Social Performance (PSP) Scale Score [ Time Frame: Screening, and Week 8, 16, 24, 38 and 50 ] [ Designated as safety issue: No ]
    The PSP scale assesses the degree of a participant's dysfunction (ranging from i [absent] to vi [very severe) within 4 domains of behavior: socially useful activities, personal and social relationships, self-care, disturbing and aggressive behavior. The overall score ranges from 1 to 100. Based on the 4-domains there was one total score. Participants with a score of 71 to 100 had a mild degree of difficulty; from 31 to 70, varying degrees of disability; participants with scores of 30 or less function so poorly as to require intensive supervision.
  • Global Assessment of Functioning (GAF) Scale Score [ Time Frame: Screening, and Week 8, 16, 24, 38 and 50 ] [ Designated as safety issue: No ]
    The GAF scale is a 100-point tool rating overall psychological, social and occupational functioning of adults. The higher score range (91-100) refers to a superior functioning in a wide range of activities, and absence of symptoms. The lower score range (1-10) refers to persistent danger of severely hurting self or others; or persistent inability to maintain minimum personal hygiene; or serious suicidal act with clear expectation of death.
  • Clinical Global Impressions (CGI) - Disease Severity score [ Time Frame: Baseline up to Week 24 ] [ Designated as safety issue: No ]
    The CGI rating scale is a 7 point global assessment that measures the clinician's impression of the severity of illness exhibited by a participant. 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 participants". Higher scores indicate worsening.
  • Extrapyramidal Symptoms Rating Scale (ESRS) total score [ Time Frame: Baseline up to Week 24 ] [ Designated as safety issue: Yes ]
    The ESRS is used to assess four types of drug-induced movement disorders administered as a questionnaire. Score range from 0 to 6 (0 is absent and 6 is extremely severe).
  • Drug Attitude Inventory (DAI-10) [ Time Frame: Screening up to Week 24 ] [ Designated as safety issue: Yes ]

Switching From Oral Antipsychotics to Long-Acting Risperidone in Participants With Schizophrenia
An Open-Label Study of Oral Antipsychotics Replacement by Prolonged Release Risperidone (Risperdal Consta) in Schizophrenic Subjects With Bad Adhesion to the Treatment

The purpose of this study is to evaluate efficacy, safety and tolerance of long-acting risperidone when switching from oral antipsychotics in participants with schizophrenia (psychiatric disorder with symptoms of emotional instability, detachment from reality, often with delusions and hallucinations, and withdrawal into the self).

This is an open-label (all people know the identity of the intervention), multi-centric (conducted in more than one center) and non-comparative study of long-acting risperidone in participants with schizophrenia who have a previous history (in the last 12 months) of bad adherence to the oral antipsychotic treatment of first or second generation. The duration of this study will be 24 weeks and will include following visits: Screening, Baseline, Week 2, 4, 8, 12, 16, 20, 24, 38 and 50 (End visit or early withdrawal). All the eligible participants (after risperidone intolerance test during screening) will receive a dose of 25 milligram risperidone every two weeks by intramuscular injection (injection of a substance into a muscle). Efficacy and safety of the participants will primarily be evaluated by Positive and Negative Syndromes Scale and Extrapyramidal Symptom Rating Scale, respectively. Participants' safety will be monitored throughout the study.
