The contingency management portion of this condition was adapted from Iguchi, Belding, Morrel, and Lamb (1997) and Petry et al. (2000), and used a fishbowl-drawing procedure for determining amount of reinforcement (Petry & Martin, 2002). Participants earned drawings from the fish bowl if they provided verification of completed network building assignments. Half of the slips in the fishbowl could be redeemed for services or merchandise. During the 12 weeks of study participation a maximum of 234 drawings could be earned. Patients in the NS+CM condition earned on average 56 draws and redeemed $250.00 worth of prizes.
