Phenomenological research has become increasingly popular in occupational therapy in recent years. However, phenomenological inquiry is one of the most philosophically and theoretically complex research traditions, many aspects of which remain poorly understood. This article is intended for individuals either interested in or about to conduct phenomenological research. It examines the conceptual foundations of phenomenology, particularly Heideggerian phenomenology, including an exploration of the concept of Being. A case example of how these concepts can be developed within an occupationally focused research project is presented. The article concludes with reflections on the value of phenomenological research in understanding complex, situated phenomena of interest to occupational therapists.
