Treatment intensity is an aspect of communication intervention that has received limited empirical attention. In this article, we discuss key parameters of treatment intensity related to individuals with complex communication needs who use augmentative and alternative communication. We advocate for an examination of treatment intensity along with learner and intervention characteristics that may moderate or mediate treatment intensity. In addition, we discuss the influence that contextual fit/treatment acceptability may have on intervention success. We also discuss the challenges created by a number of interacting variables that make determining optimal dosage for groups of individuals difficult. Finally, treatment intensity is briefly discussed in terms of its possible influence on maintenance and generalization.

治疗强度是交流干预的一个方面，但在经验上受到的关注有限。在本文中，我们讨论了与使用辅助和替代交流的具有复杂交流需求的个人相关的治疗强度的关键参数。我们提倡检查治疗强度以及可能缓和或调节治疗强度的学习者和干预特征。此外，我们讨论了情境适合/治疗可接受性可能对干预成功的影响。我们还讨论了由许多相互作用的变量造成的挑战，这些变量使得确定个体群体的最佳剂量变得困难。最后，根据治疗强度对维持和泛化的可能影响，简要讨论了治疗强度。
