The UNITES project was commissioned (in 2022) by the Department of Children Equality Disability Integration and Youth (DCEDIY). The project involved two separate, but related stages, the aims of which were: (1) to profile and critically review home visiting provision in Ireland (Stage One); and (2) to elicit the insights, views and experiences of a wide range of stakeholders involved in managing, implementing, delivering or receiving home visiting programmes and services across the country with a view to identifying some proposed actions or ‘options’ that may provide key stepping stones toward a more standardised, effective and sustainable ‘model’ of home visiting service delivery in Ireland (Stage Two). This report presents the findings from Stage One of the UNITES project. The results of Stage Two are described in a second companion report (McGilloway et al., 2024). The aims of Stage One were to: (1) map/scope out home visiting service provision in Ireland; and (2) to critically examine relevant evidence of effectiveness and implementation produced in a national context. The specific objectives of this desk-based study (each of which corresponds to a separate section in this report) were to: 1. Profile, map and describe current home visiting provision across Ireland 2. Examine the development and nature of provision 3. Assess the evidence of impact/outcome achievement based on the academic literature and 4. Explore aspects of implementation.
