This article contributes to the current discussions calling for more reflexivity in Participatory Design (PD). We offer an account of our experiences with reflexivity from a study in which a social media supported collaboration model was designed by and for professionals working with the topic of workplace harassment. This article draws from the researchers' interdisciplinary frames as we locate reflexivity in the current PD discourses and in the experiences of our study. We introduce the concept of reflexive engagement, which we describe as an orientation to design and research that has the potential to influence design, extend conceptual discoveries, and afford a way to balance the research-design gap. We conclude by encouraging the PD community to embrace reflexivity as a way to address current practical and disciplinary challenges. While our focus in this article is on PD, we also see the potential of reflexive engagement for other user-centric or collaborative design approaches in Information and Communication Technologies (ICT).
