This presentation is an introduction to case conceptualization for sleep problems, walking through the process from assessment to intervention with research and clinical examples throughout. We will start with a brief education on sleep science, how common sleep problems are, and why sleep is important to address. Next, we will look at sleep through a behavior analytic lens, including defining behavioral quietude and how it can be taught. From there, we will introduce practical tools for assessing sleep problems and prioritizing what to address first. This includes a detailed walkthrough of the Sleep Assessment and Treatment Tool (SATT) and examples from the research where it was used to guide effective treatment. We will then explore common interventions used for specific sleep problems. Throughout, the focus is on using what we learn about each case to choose the least restrictive approach to support better sleep.
