Brief Summary

Public health organizations in Denmark and most Organization for Economic Cooperation and Development (OECD) countries face an urgent demand for nursing staff. However, existing research does not yet offer a systematic understanding of how to attract talent to public healthcare organizations from the international labor markets. In this study, the researchers will collaborate with a network of Danish public healthcare service providers led by the implementation partner Copenhagen Capacity to implement a large-scale megastudy (n=110,000), aimed at recruiting nurses and nursing assistants from across the European Union to Denmark. The study takes an employer-driven recruitment approach, co-designing and implementing a national recruitment campaign that uses social media job platforms to identify and contact potential recruits with a direct, personal message coming from a national recruitment agency. The study aims to answer three research questions: Research Question 1: Does receiving a behaviorally informed recruitment message (relative to a message with no employer value proposition) motivate a prospective employee to engage? Research Question 2: Does receiving any recruitment message (relative to receiving no message) motivate a prospective employee to engage? Research Question 3: What factors - that could be emphasized as employer value propositions in a short message - would motivate a prospective employee to engage? Study participants will be randomly assigned to one of 10 treatment conditions in which they'll receive a recruitment message highlighting different employer value propositions or a simplified message including no employer value proposition, or to a control group that will receive no message. Researchers will analyze differences across groups in terms of engagement after receiving a recruitment message, which can involve accepting, declining, responding to the message, clicking on a link within the message, and in this link registering to a national database to receive regular newsletters featuring job advertisements.

Data Sharing

IPD Sharing
Will share

To avoid inadvertently disclosing participants' sensitive personal information, we cannot provide the full megastudy data publicly. However, we will provide a reduced dataset that includes the trial arm assignment, outcome variables, covariates, and an anonymized ID representing each individual. We restrict precise geographical information (e.g., replacing postal codes with broader regional descriptions) to ensure that no combination of variables can identify a group smaller than five individuals. This approach allows researchers to reproduce our main results without risking the potential de-anonymization of participants. De-identified data and materials will be made publicly available on Open Science Framework (OSF).
