Toward greater involvement of youth with complex communication needs in the selection of augmentative and alternative communication devices.

The study aim was to examine the measurement properties of the Youth Evaluation of Products Scale for Augmentative and Alternative Communication (YEP-AAC) as a means to understand the product attitudes of youth toward their AAC devices. In study 1, four males and two females between the ages of 8 and 17 years (median age = 14 years) participated in face-to-face interviews. A researcher administered the YEP-AAC and then asked youths to explain the rationale for their item ratings.
