TABLE 2—(Continued) Study Magiati & Howlin (2003) Schwartz et al. (1998) Tincani (2004) PECS acquisition, (b) frequency of spontaneous requests initiated by participants, (c) method and function of <strong>the</strong> participants’ communication, and (d) number of pictures and spoken words used by <strong>the</strong> participants following introduction of PECS. In addition, participants’ behavior outcomes were measured in three studies, Anderson (2002), Charlop- Christy et al. (2002), and Magiati and Howlin (2003). The behavior outcomes examined included frequency of problem behaviors participants engaged in and <strong>the</strong> incidence of frustration showed by participants.

The summary includes a description of <strong>the</strong> influence of <strong>the</strong> PECS training on functional communication outcomes as reported in each study. In addition, it contains information about <strong>the</strong> degree to which change in communication status was demonstrated as a direct result of <strong>the</strong> PECS training. As illustrated, Natural Intervention Setting Intervention Agent <strong>the</strong>re was little variation across <strong>the</strong> 13 studies regarding <strong>the</strong> specificity of documenting appropriate implementation of PECS. For purposes of <strong>the</strong> syn<strong>the</strong>sis, studies that lacked data demonstrating implementers’ mastery of <strong>the</strong> PECS skills were categorized as having Low Specificity (N 0; 0 %). Studies that provided evidence of implementers’ mastery of PECS skills but did not report any treatment-fidelity procedures were categorized as having Moderate Specificity (N 9; 69%). Finally, studies that provided data regarding implementers’ skill mastery and <strong>the</strong> treatment fidelity procedures used were classified as High Specificity studies (N 4; 31%). The studies with High Specificity provided <strong>the</strong> strongest evidence that change in communication outcomes were a direct consequence of <strong>the</strong> PECS training.

TABLE 3 Major Findings Study Communication Consequences O<strong>the</strong>r Consequences Adkins & Axelrod (2002) Anderson (2002) The use of PECS produced a better acquisition rate, more spontaneous usage, and a higher generalization rate than <strong>the</strong> use of sign language for <strong>the</strong> child with PDD. PECS was a more effective method for <strong>the</strong> child with PDD, and it generalized under different conditions. PECS was <strong>the</strong> preferred response method used by <strong>the</strong> child. The child began to imitate some sounds and onesyllable words For <strong>the</strong> majority of <strong>the</strong> children, rates of acquisition in <strong>the</strong> PECS condition were uniformly faster than rates of acquisition in <strong>the</strong> sign language condition. All of <strong>the</strong> children mastered more items in <strong>the</strong> PECS condition than in <strong>the</strong> sign language condition. All <strong>the</strong> children demonstrated response generalization in <strong>the</strong> PECS condition; four out of <strong>the</strong> six children demonstrated skill generalization in <strong>the</strong> sign language condition. Three of <strong>the</strong> children appeared to behaviorally prefer PECS; <strong>the</strong> o<strong>the</strong>r three children appeared to behaviorally prefer sign language. All <strong>the</strong> children initiated with PECS more often than with sign language when both modalities were available. The three children who appeared to prefer sign language initiated <strong>the</strong> greatest number of sign trials during <strong>the</strong> free choices without PECS probes. The child appeared to be able to achieve correspondence to <strong>the</strong> presented object. Five of <strong>the</strong> six children demonstrated more eye contact in <strong>the</strong> sign language condition than in <strong>the</strong> PECS condition. Several children began vocalizing during treatment in both <strong>the</strong> sign language and PECS conditions. However, <strong>the</strong> three children who vocalized during correct responding did so significantly more often in <strong>the</strong> sign language condition than in <strong>the</strong> PECS condition. Tantrum and avoidance behaviors decreased for all <strong>the</strong> children in both PECS and sign language conditions. Three of <strong>the</strong> six participants demonstrated significant increases in positive affect in <strong>the</strong> sign language condition, while only one significant increase was found in <strong>the</strong> PECS condition. Two children demonstrated more self-stimulation in <strong>the</strong> sign language condition, while two children engaged in significantly more selfstimulated in <strong>the</strong> PECS condition.
