Although the results of the above mentioned psychotherapy trials, as well as a number of pharmacological treatment trials, are promising (Cook et al., 2001; DeVeaugh-Geiss, Moroz, Biederman, & Cantwell, 1992; Geller et al., 2001; Liebowitz et al., 2002; March et al., 1998; Riddle et al., 2001), it is important to note that a relatively large number of patients do not respond to treatment in a clinically significant manner. For example, the treatment response rates in recent major drug trials ranged from 42 to 67% (Cook et al., 2001; DeVeaugh-Geiss et al., 1992; Geller et al., 2001; Liebowitz et al., 2002; Riddle et al., 2001), whereas the treatment response rate in the referenced psychotherapy trials ranged from 63 to 79%. As such, it is important to identify and test potential treatment approaches that may be suitable for treatment refractory pediatric OCD patients.
