| Abstract: | Adolescents with complex communication needs require interventions based on community communication skills for effective communication within the expanding scope of their lives. This study aimed to compare two augmentative and alternative communication (AAC) interventions by using script for their effectiveness in helping four adolescents with complex communication needs to express themselves in the community. The devices used in the study were a location-based and a category-based high-tech AAC device used in an alternative treatment design. The two intervention methods were alternated during the intervention phase of the study to determine the more effective one. The effect size was calculated using an improvement rate difference (IRD) analysis. Then, the more effective method was applied instead of the less effective one in the replication phase, within the setting where the less effective method had previously been employed, to assess its effectiveness. and effective AAC communication methods were employed within the community during the generalization phase. As a result of the interventions, all four participants showed increased accuracy of expression in the local community compared with the baseline, and the location-based tool showed greater treatment effects than the category-based tool. Additionally, the location-based device also showed generalization effects in the local community. The findings confirmed the efficacy of the two different AAC tools to improve the accuracy of expression among adolescents with complex communication needs, facilitating their integration into the community. |
