The SWN-K is comprised of 20 questions, each of which is rated using a 6-point scale ranging from 1 (not at all) to 6 (very much). Possible scores range from 20 to 120, with higher scores implying higher subjective well-being.

The SWN-K total score is the sum of 5 subscores (4 questions each): physical functioning, social integration, mental functioning, self-control, and emotional regulation. The subscores are rated using a 6-point scale (the higher the grade, the better the response). Possible subscores range from 4 to 24.

Remission was defined as a SWN-K total score greater than or equal to 80. The reported population is participants who showed remission over, time from baseline to Month 12

For the CGI-SCH overall severity of illness, the score ranged from 1 (normal, not ill) to 7 (among the most severely ill). CGI-SCH score was divided into 3 classes: worsening (change score>0), stable (change score=0) and improved (change score<0). Change from baseline in CGI-SCH overall severity of illness in number of participants with CGI-SCH overall severity score improvement.

For the CGI-SCH (Clinical Global Impression-Schizophrenia severity of illness scale) overall severity of illness, the score ranged from 1 (normal, not ill) to 7 (among the most severely ill). Change from baseline in CGI-SCH score was divided into 3 classes: worsening (change score>0), stable (change score=0) and improved (change score<0).

The CDSS total score is the sum of 9 questions and ranges from 0 to 27. The higher the score, the more severe are the symptoms.

Relapse is defined as at least one increase of greater than or equal to 2 points on the CGI-SCH overall severity score during the treatment period or at least one hospitalization due to psychiatric disorders during the treatment period.

The Euro Quality of Life - 5 dimension index (EQ-5D) is the result of the application of a formula that essentially attaches values (also called weights) to each of the levels (no, some, or heavy problems) in each dimension (mobility, self-care, usual activities, pain/discomfort, anxiety/depression). These weights are issued from a representative sample of the general population. The total possible maximum value was 1 (healthy life) and the minimum value was 0 (death).

Stable State was defined as having the same status in occupational and residential status as at Baseline.

Workers and students are defined from the modified vocational status index excluding subjects "Retired" or "Unemployed, whether or not expected to work".
