Trait authenticity as an “enzyme” for personal resources and work engagement: A study among teachers within the framework of the job demands-resources model

Introduction. – Trait authenticity has been defined as a dispositional individual difference, and it refers to people’s experience of living in accordance with their true Self. Despite research conducted in working contexts has found that trait authenticity is related to people’s work engagement, it is not clear if this association may be mediated by other variables. Objective. – Framing trait authenticity within the job demands-resources model, we hypothesized that trait authenticity allows the release of human full potential in terms of personal resources that, in turn, promote work engagement, especially in highly challenging work settings, such as educational ones. Method. – We administered a self-report questionnaire composed of several measurement scales to 446 teachers working in kindergartens, primary schools, and middle schools. Results and conclusions. – A moderated mediation analysis revealed that trait authenticity can promote teachers’ emergence of personal resources, which in turn enhances their work engagement. The study highlights that the role of trait authenticity and personal resources on work engagement acquires a particular salience when teachers face high (vs. low) challenge job demands (i.e., workload), that is when this reservoir of potential is needed the most.
