• Positive psychology interventions (PPIs) in the work context aim to enhance the experience of work for individuals and improve wellbeing through developing psychological resources. This chapter reviews four types of positive interventions: gratitude, mindfulness, positive reflection, and positive reappraisal, and discusses their effectiveness based on past research. We then discuss several key considerations for implementing positive psychology interventions in the workplace, considering when and for whom they are beneficial. Finally, we conclude with our reflections on what future research and the practical application of positive psychology interventions in the workplace should strive for.
