1b Fundamentals program:  Students received a list of 9 
behaviours that are typical for happy people and worked 
on at least 3 of these each day:
1c Activities program: Assignments were given to help 
students think about their personal happiness and the 
kinds of situations and activities that made them happy 
to develop a list of  \t least 10 items on a) what 
usually made them happy, b) they would do almost everry 
day and c) they normally did not take the time to do. 
Students then practiced at least 3 of these activities

erase initial differences between treatment and 
control groups and made using covariance.
