    -then all the patients undertook the primary measures again
  • then the intervention group did the 10 week CBT
  • all the patients again did the primary measures.
  • lastly the control group did the 10 week CBT.
17
Q

results of Williams et al

A

using Becks depression inventory,
intervention group went from 28 to 10 from initial test to after all treatments.
meanwhile the control group went from 28 to 20.5 after just their CBT.

CBM was 7 40 minute sessions completed daily for a week.

19

10 weeks with homework
