as well as connections with more distant acquaintances 
and strangers, and (d) 1 mudule focusing on program 
reflection, person–activity fit, and habit development.
Each module follows a three-part format with (a) a 
didactic learning component, (b) an activity to put the 
principle into practice, and (c) companion writing 
activities

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.
