FSQ Work Score = Functional Status Questionnaire Work Subscale Score standardized from 0–100, 100= optimal work performance; Hamilton Depression Rating Scale Score ranges from 0–54, 0–13= no to mild symptoms and ≥14= moderate to severe symptoms; Hamilton Anxiety Rating Scale Score ranges from 0–56, 0–17= no to mild symptoms and ≥18= moderate to severe symptoms
