Fidelity to cognitive behavioral therapy: Adherence to the CBT model will be assessed by an adapted form of the Revised Cognitive Therapy Scale (CTS-R; Milne et al., 2001). The group therapy version is comprised of seven items rated on a 0-6 likert scale, with rating of "3" or greater on each item indicating fully-competent practice compared to the average skilled clinician. Prior studies using the group therapy version of the CTS-R has found good to excellent interrater reliability (Lysaker et al., 2009). Furthermore, fidelity will be assessed using audio recordings of three random sessions per CBTw group and will be conducted by a blinded member of the study team trained in CBT fidelity by Dr. Kukla.
