About this study

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Any engagement with recruitment message

    A binary indicator defined at the individual level, where 1 indicates that the individual, up to 4 weeks after receiving the message, accepted or declined the recruitment message, and/or wrote a text response to the recruitment message, and/or clicked on the link within the message.

    Measured: Up to 4 weeks after reception of recruitment message

Secondary outcomes (3)
  1. Positive engagement with recruitment message

    A binary indicator defined at the individual level, where 1 indicates that the individual, up to 4 weeks after receiving the message, accepted the recruitment message, and/or wrote a text response to the recruitment message, and/or clicked on the link within the message. Otherwise, the variable equals 0.

    Measured: Up to 4 weeks after reception of recruitment message

  2. Click on the landing page

    A binary indicator at the individual level, where 1 indicates that the individual clicked the link to access the recruitment landing page up to 4 weeks after receiving the recruitment message. Otherwise, the variable equals 0.

    Measured: Up to 4 weeks after reception of recruitment message

  3. Registration to the national database

    A binary indicator at the individual level, where 1 indicates that the individual submitted their email address to sign up to the national database up to 12 weeks after receiving the recruitment message (or having been expected to receive the recruitment message had they not been assigned to the control group).

    In the event that a study participant registers to the national database prior to having received a recruitment message (or for the control group, prior to the date they would have received the recruitment message), and in all other cases, the variable equals zero.

    Measured: Up to 12 weeks after after receiving the recruitment message (or having been expected to receive the recruitment message had they not been assigned to the control group)

Individual data sharing
Yes: 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).

Questions about this trial

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?
