Therapist adherence to a manualized cognitive-behavioral anger management group treatment (AMT) was compared between therapy delivered via videoconference (VC) and the traditional in-person modality, using data from a large, randomized controlled trial comparing the effectiveness of AMT for veterans with combat-related posttraumatic stress disorder. Therapist adherence was rated for the presence or absence of process and content treatment elements. Secondary analyses were conducted using a repeated measures ANOVA. Overall adherence to the protocol was excellent (M = 96%, SD = 1%). Findings indicate that therapist adherence to AMT is similar across delivery modalities and VC is a viable service delivery strategy that does not compromise a therapist's ability to effectively structure sessions and manage patient care. © 2011 Wiley Periodicals, Inc.
