This study investigated the effects of animal-assisted therapy (A-AT)
on self-reported depression in a college population. Forty-four partic
ipants were selected on the basis of scores on the Beck Depression Inv
entory (BDI). They then were assigned to one of three groups: A-AT in
conjunction with psychotherapy (directive group), A-AT only (nondirect
ive group), and control. Standardized regressed BDI posttest scores we
re used as dependent variables in one-way analysis of variance with tr
eatment as the independent variable. Results revealed significant diff
erences among groups, F(2, 41) = 3.69, p < .05. Duncan's Multiple Rang
es Test indicated that standardized regressed BDI posttest scores diff
ered significantly between nondirective (M = 5.67) and control groups
(M = 10.18).
