Sampling Frame and Participant Recruitment
CAMS recruited a volunteer sample of children and
adolescents between the ages of 7 and 17 years. Inclusion
and exclusion criteria are presented in Tables 1
and 2. A complete description of the clinical characteristics
of the sample can be found in Kendall and colleagues
[43].
With the exceptions noted below and in Table 2,
CAMS investigators sought to enroll a sample of
anxious youth representative of the full range of ethnic/
minority backgrounds and as similar as possible to those
seen in general clinical/hospital practice and community
clinical settings. Youth with a co-primary diagnosis
(defined as an ADIS CSR equal to that of at least one of
the target disorders) for which a different disorder-specific
treatment was indicated were not included (i.e.,
substance abuse disorder, eating disorder). However, to
enhance the generalizability of the results, youth with an
Axis I disorder(s) with an ADIS CSR less than that of
one of the target disorders, with the exception of those
disorders listed in Table 2, were included to ensure a
broadly representative sample of anxious youth. Given
that children with major depressive disorder (MDD)
respond to SSRIs and that standard CBT for anxiety disorders
does not specifically target symptoms of depression,
participants who met DSM-IV criteria for MDD
(at any ADIS CSR level) were excluded. This decision
was made to ensure a sample whose outcomes could be
most clearly interpreted as related to the anxiety disorders
of interest.
