N2 - In their comments on the authors' article (M. Siemer & J. Joormann, 2003), R. C. Serlin, B. E. Wampold, and J. R. Levin (2003) and P. Crits-Christoph, X. Tu, and R. Gallop (2003) took issue with the authors' suggestion to evaluate therapy studies with nested providers with a fixed model approach. In this reply, the authors comment on Serlin et al.'s critique by showing that their arguments do not apply, are based on misconceptions about the purpose and nature of statistical inference, or are based on flawed reasoning. The authors also comment on Crits-Christoph et al.'s critique by showing that the proposed approach is very similar to, but less inclusive than, their own suggestion.
