Together with Nanna Vestergaard Ahrensberg, Jesper Asring Jessen Hansen,\u00a0Jakob Majlund Holm, and Simon Calmar Andersen, I have a new study out in JPART on Implementation and its support (link below). It’s called “Implementation Support: A Field Experiment on the Effects of Fidelity and Professional Responsibility Approaches”.<\/p>\n\n\n\n
Anyone who has worked with public policies or social interventions knows the familiar frustration: even the best-designed programs often fail to deliver the expected results once they meet real-world practice. Over the years, researchers and practitioners have identified a long list of barriers to implementation\u2014lack of time, competing priorities, limited buy-in, and organizational constraints, to name just a few.<\/p>\n\n\n\n
But one aspect has received surprisingly little attention: how implementation support itself is framed<\/strong>.<\/p>\n\n\n\n In a new article, \u201cImplementation Support: A Field Experiment on the Effects of Fidelity and Professional Responsibility Approaches,\u201d<\/em> we explore whether seemingly small differences in implementation support can shape behavior\u2014and ultimately outcomes\u2014in meaningful ways.<\/p>\n\n\n\n The starting point of the study is a simple distinction between two ideal-typical approaches to implementation support:<\/p>\n\n\n\n Both approaches are widely used in practice, often implicitly. Yet we know surprisingly little about their causal effects.<\/p>\n\n\n\n To address this gap, the study reports results from a large-scale, preregistered field experiment involving 250 Danish schools<\/strong> implementing the evidence-based reading intervention READit. The intervention consists of a bag of books and good advice for parents of children in grades 1 and 2 on how to read with their children. Also, READit provided access to an online ressource containing more e-books in several languages.<\/p>\n\n\n\n Schools were randomly assigned to receive implementation support framed either around fidelity or professional responsibility.<\/p>\n\n\n\n The results show that framing matters<\/strong>\u2014even when the differences are subtle.<\/p>\n\n\n\n At the family level, schools receiving a professional responsibility approach<\/strong> saw higher take-up of the program and, to some extent, greater use of the intervention. Importantly, this was not driven by formal requirements or incentives. Instead, a plausible mechanism appears to be increased encouragement from teachers<\/strong>, as reported by parents.<\/p>\n\n\n\n In other words, when teachers were given more discretion and responsibility, they seemed more inclined to actively promote the intervention to families.<\/p>\n\n\n\n At the same time, one finding may come as a surprise: teachers themselves reported higher appreciation for the fidelity approach<\/strong> in terms of the feasibility and appropriateness of the READit intervention. Clear guidelines and standardized expectations may simply make daily work easier\u2014especially in busy school environments where time and cognitive resources are scarce. <\/p>\n\n\n\n Taken together, these findings highlight a central trade-off in implementation support.<\/p>\n\n\n\n On the one hand, a fidelity approach can reduce uncertainty and ease teachers\u2019 workload in the short run. From an organizational perspective, this is attractive\u2014and may help explain why fidelity-oriented support is so common.<\/p>\n\n\n\n On the other hand, the professional responsibility approach appears to generate greater benefits for the target group<\/strong>. By activating teachers\u2019 sense of ownership and discretion, it seems to translate more effectively into behavioral change among families.<\/p>\n\n\n\n This suggests that implementation support is not just a technical add-on to policy design. It is a behavioral intervention in its own right<\/strong>, shaping how frontline professionals engage with both the program and its intended beneficiaries. Striking the right balance between approaches to implementation support in terms of timing, beliefs among professionals, and the needs and actions of target groups seems to be a fundamental challenge for leaders in the public sector.<\/p>\n\n\n\n The broader implication is that policymakers and organizations should think more carefully about the messages they send when rolling out interventions. Even minor changes in framing\u2014without additional resources or structural reforms\u2014can have detectable consequences.<\/p>\n\n\n\n Rather than asking only \u201cAre implementers following the program?\u201d<\/em>, we might also ask:<\/p>\n\n\n\n There is no one-size-fits-all answer. But if the goal is to maximize benefits for target groups, granting professionals meaningful discretion may be more powerful than we often assume.<\/p>\n\n\n\nTwo Ways of Supporting Implementation<\/h3>\n\n\n\n
