Many common work situations are conducive to the experience of performance anxiety. However, knowledge of performance anxiety in the workplace is still limited. None of the definitions in the literature seems to represent this complex phenomenon well. This article therefore attempts a first conceptualization of performance anxiety in the workplace based on the current literature. More precisely, an analysis of different definitions and scales dealing with performance anxiety in various domains has been carried out. The proposed conceptualization is composed of four dimensions: somatic, cognitive, behavioral and affective manifestations. This operationalizable conceptualization will allow the authors to continue their work in developing a measurement scale.
