followed by 12 weeks ENHANCE

No differences between in person and online mode, so 
analyzed as 1 group.

Change between groups significant for positive 
affect post treatment (p<0.01)and at follow-up 
(p<0.05). Change between groups significant for 
negative affect at post treatment only (p<0.01). 
Thus change in AB between groups significant post 
treatment.
