“…Researchers that have reviewed the literature draw attention to the methodological flaws that characterize most empirical research in this area (e.g., Fuchs, Fuchs, Dulan, Roberts, & Fernstrom, 1992;Gresham & Kendell, 1987;Gutkin, 1993;Pryzwansky, 1986) and point out that few well-controlled studies have actually been conducted (Kratochwill & VanSomeren, 1985). Only a few group-design studies have been experimental in nature, and much of the single-case designs have involved only one or two subjects (Fuchs et al, 1992), bringing the external validity of these investigations into question. The limited database and methodological flaws further limit the level of confidence in the outcome literature on consultation.…”
