“…The Plan provided us with a standard-a ruler-against which the therapist's interventions could be compared to evaluate the goodness-of-fit of each intervention for each particular patient. Recently, researchers from other theoretical orientations have focused on developing their own instruments for including the variable of accuracy of interpretations (Crits-Christoph, Cooper, Crits-Christoph, Luborsky, Dahl, Popp, Mellon, & Mark, 1988); some have focused on the categories of interpretations (Piper, Azim, Joyce, & McCallum, 1991;Piper, Debbane, Bienvenu, de Carufel, & Garant, 1986;Piper, Debbane, de Carufel, & Bienvenu, 1987); some have investigated both (Fried, Crits-Christoph, & Luborsky, 1992;Crits-Christoph, Demorest, & Connolly, 1990;Horowitz, 1987;1991;Luborsky & Crits-Christoph, 1990;Luborsky, Crits-Christoph, & Mellon, 1986;Perry, 1989;Perry, Luborsky, Silberschatz, & Popp, 1989;Strupp & Binder, 1984).…”
