Observational Study in Patients With Schizophrenia Treated With Long-Acting Risperidone Injection (RISPERDAL CONSTA)

The CGI-S is a 7-point scale ranging from 1 to 7 (normal, not at all ill to among the most severely ill patients), which measures disease severity in psychiatric patients. The scale is completed by physician.

The CGI-C is a 7-point scale ranging from 1 to 7 (very much improved to very much worse), which is used to rate the change in the patient's illness compared to baseline. The scale assesses the patient's improvement over time. The scale is completed by physician.

GAF is completed by the physician. GAF is a single item rating of the patient's psychological, social, and occupational functioning on a hypothetical continuum of mental health-illness. Respondents are asked to rate the subject's lowest level of functioning in the last week. GAF scores range from 0 to 100. (0 = Inadequate information, 1 = Persistent danger of severely hurting self or others and 100 = Superior functioning in a wide range of activities).

The PSP Scale is completed by the physician. PSP is a rating of a patient's level of functioning during the past month in 4 areas: (a) socially useful activities (including work and study); (b) personal and social relationships; (c) self-care; and (d) disturbing and aggressive behaviors. Scores range from 1 to 100. (1= Lack of autonomy in basic functioning and 100 = Excellent functioning in all 4 main areas).

The Strauss-Carpenter LOF is completed by the physician. It consists of 9 items that can be grouped into 4 subscales: symptoms (absence of symptoms and recent hospitalizations), social contacts (frequency and quality of social contacts), work (quantity and quality of useful work), and function (ability to meet basic needs, fullness of life, and overall level of function). Each item is rated on a scale of 0 (worst functioning) to 4 (best functioning).

Patients completed the SF-36. The survey includes 36 items and evaluates health status in the past 4 weeks, in 8 different areas, which can be broadly summarized as physical health (physical functioning [PF], role-physical [RP], bodily pain [BP] and general health [GH]) and mental health (vitality [VT], social functioning [SF], role-emotional [RE], and mental health [MH]). In addition, the SF-36 evaluates health status in 2 broadly-defined areas, mental health and physical health. Higher scores represent better health status.

Patients are asked a single question to evaluate patient satisfaction with their current Anti psychotic medication. The question is, "The way I feel about my current antipsychotic is:" and used a 7-point response scale from 1 to 7 (extremely dissatisfied to extremely satisfy).

Healthcare resource utilization including dates of hospitalizations (inpatient), emergency room (ER) visits, and outpatient visits, consultations with specialists and general practitioners. Relapse rates (from psychiatric hospitalizations, suicidal behavior or homicidal behavior) are also captured as resource utilization.
