The results of this review indicate that the Picture Exchange Communication System (PECS) is widely used, but does not have a strong empirical base. Findings suggest that there may not be a single most effective communication system, but rather that a multimodal approach may be most appropriate. For example, PECS may be appropriate for manding and tacting but other approaches may be necessary for asking questions and developing social closeness. Additionally, considerations should be made for transitioning PECS users to more appropriate long-term communication interventions (that can accommodate larger vocabularies and more mature mediums for communication).
