“…Thus, we provide a deeper understanding of the psychological sources of PSM (van Witteloostuijn, Esteve, and Boyne 2017) and offer a complementary perspective on the existing theoretical PSM framework. Second, by focusing on two specific forms of OCB, we provide a firmer understanding of the relationship between PSM and citizenship behaviors (Bozeman and Su 2015;Ritz, Vandenabeele, and Vogel 2021;Schott, Steen, and Van Kleef 2019) and complement the literature on OCB in the context of public administration (Bentein et al 2021;de Geus et al 2020). Third, by examining the links between regulatory orientations, PSM, and OCB with a three-wave design, we not only shed light on how self-regulation processes may be related to individuals' propensity to serve the public interest but also provide important insights into whether and how individual-level predictors shape public service motivation to promote OCB.…”
