The current study compared and assessed the effectiveness of the Minnesota model in reducing psychological symptoms of anxiety and depression among two groups: individuals with clinically diagnosed addiction only ( n = 29) and individuals with clinically diagnosed anxiety/depression in the absence of addiction ( n = 25). Anxiety and depression were measured using the Generalised Anxiety Disorder 7 and the Patient Health Questionnaire 9, respectively. Two one-way analyses of covariance found no significant differences in post-intervention anxiety and depression scores when comparing the addiction group and the anxiety/depression group ( F (1, 51) = 0.075, p = 0.786 and F (1, 51) = 0.302, p = 0.585, respectively). Reliable change index calculations also indicated that both the addiction group and the anxiety/depression group exhibited clinically significant reductions in anxiety and depression following treatment. These findings are considered in light of key methodological limitations, and the theoretical and therapeutic implications are discussed.
