Outcome Measures

Primary Outcomes (1)

  • Change from baseline in Montgomery Asperger Depression Scale (MADRS) score at the end of treatment (week 8)

    The MADRS is a clinician-rated scale to assess depressive symptomatology during the preceding week. Participants are rated on 10 items (feelings of sadness, lassitude, pessimism, inner tension, suicidality, reduced sleep or appetite, difficulty concentrating, and lack of interest) each on a 7-point scale from 0 (no symptoms) to 6 (symptoms of maximum severity). The total score ranges from 0 to 60 with a higher score indicating more depression. A negative change score indicates improvement.

    Baseline and week 8

Secondary Outcomes (9)

  • Change from baseline in Hamilton Depression Scale (HAMD-17) at week 1, 2, 4, 6, 8

    Baseline, week 1, 2, 4 ,6 and 8

  • Change from baseline in Hamilton Anxiety Inventory (HAMA) scores at week 1, 2, 4, 6, 8

  • Change from baseline in MADRS score at week 1, 2, 4, 6
