Note: Participants from Kendall et al. (1997) included 94 participants who completed the initial randomized clinical trial as well as 24 additional participants who were in the intent-to-treat sample. Participants from Kendall et al. (2004), also referred to as the 7.4 year follow-up time point, were recruited from the sample of treatment completers from Kendall et al. (1997). For the most recent 7 to 19 year follow-up (i.e., Benjamin et al., 2013), participants were recruited from the entire Kendall et al. (1997) intent-to-treat sample as well as participants from Kendall et al. (2008) who (a) had been randomized to receive individual CBT and (b) were over 18 years of age at the time of recruitment for the 7 to 19 year follow-up. This resulted in an N at the 7 to 19 year follow-up of 66.
