Pre-Post Efficacy
Time Frame: Screen and 4 weeks (immediate treatment); Baseline and 4 weeks (waitlist treatment)
|
The magnitude of the pre-post effect across 4 weeks of treatment, as measured by the Hamilton Rating Scale for Depression-17 (HAMD-17).
The HAMD-17 measures depression severity, and has a minimum value of 0 and a maximum value of 52 units on a scale, where higher scores indicate more severe depression.
