tation) and Time 3 (post AAT program) mean scores div-ided by the standard deviation of the Time 3 scores for the entire cohort (Cooper, Hedges, & Valentine, 2009). The current study aims to examine the efficacy of an AAT program incorporating structured sessions with dogs followed by social worker delivered sessions (with no dogs) that specifically refer back to, and build upon, experiences gained in the first 3 weeks, in reducing PTSD symptomatology in children who have experienced sex-ual abuse. Treatment adherence and differences (if any) in efficacy based on gender and Indigenous status will also be examined. Extant evidence suggests that AAT can be effective in lessening/improving the symptoms of PTSD, particularly those of avoidance, dissociation, and arousal, associated with child sexual abuse. Accord-ingly, it is hypothesized that trauma symptoms will sig-nificantly decrease following participation in an AAT program (Time 2 symptoms >Time 3 symptoms). It is anticipated that the change in trauma symptoms observed between intake into therapy (Time 1) and pre-AAT (Time 2) compared to the change observed pre-AAT (Time 2) and post-AAT (Time 3) will be sig-nificantly greater between Time 2 and Time 3 than Time 1 and Time 2, indicating the efficacy of the treatment. As a measure of the acceptability and broader impact of the AAT program written feedback solicited from parents/ guardians at Time 3 will also be considered.
