Five subscales: physical functioning, self-esteem, sexual life, public distress, and work, with categories in each subscale scored 1 (no trouble or difficulty) to 5 (persistent trouble or difficulty). The rescaled IWQoL-Lite score is determined by the sum of scores on all 31 items and rescaling this sum to a 1 to 100 scoring with 0=the poorest and 100=the best quality of life.
  • Number of Participants With Suicidal Tendencies (Columbian-Suicide Severity Rating Scale, [C-SSRS], Mapped to C-CASA [Columbia Classification Algorithm For Suicide Assessment])

    • C-SSRS is a participant rated questionnaire to assess suicidal ideation, suicidal behavior, actual attempts (yes or no responses), and intensity of ideation (rated 1=low severity to 5=high severity). Yes/No responses are mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) categories: Completed suicide, suicide attempt, preparatory acts toward imminent suicidal behavior, suicidal ideation, and self-injurious behavior, or no suicidal intent. A participant could have a yes or no response in more than one category.
