2019 Collaborative Science of Home Visiting

The Home Visiting Applied Research Collaborative (HARC) is pleased to announce its fourth annual Collaborative Science of Home Visiting meeting on Wednesday, January 30th, 2019 at the Grand Hyatt Washington. The meeting will be held from 8am-2pm, immediately preceding the National Home Visiting Summit.

The HARC Meeting is an interactive opportunity for HARC members to learn about innovative methods to promote precision home visiting.

The meeting agenda includes panel presentations by HARC members who use innovative research methods to study precision home visiting, as well as three concurrent workshops (see below) led by experts in the field on key concepts related to precision home visiting. Prior to the meeting, attendees will be sent suggested pre-readings and thought exercises related to their selected workshop. Attendees will come away with actionable steps to implement in their own work in the immediate future. The three workshops are:

  1. Preparing for Rapid Cycle and Adaptive Designs
    • Participants will learn about the prerequisite conditions needed to create rapid cycle and adaptive research designs. For example, participants will discuss the features of outcome variables suited to rapid cycle evaluation.
  1. Engaging Families and Key Stakeholders
    • Innovative research methods benefit from and rely on collaboration with families and other key stakeholders. Participants will learn about the continuum of family and stakeholder engagement and will consider ways to move their own research farther along this continuum.
  1. Developing Coherent and Precise Interventions
    • Programs are more likely to reach their goals when guided by a precise, coherent model that clearly defines the paths from active ingredients to outcomes. These models facilitate testing what works for whom in what contexts. Participants will learn how to develop, refine, and improve testing of a coherent and precise model.


To indicate your interest in attending the HARC Meeting, please fill out this intent form by September 30th, 2018. There is no registration fee, but spots are limited. Your registration will be confirmed by October 15th, 2018. You will select your training workshop when your registration is confirmed.


The call for abstracts is open from August 10th, 2018 to September 30th, 2018.

As part of the HARC Meeting, we are seeking abstracts for 15-minute research presentations to serve as catalysts for new ideas and discussion.

HARC aims to promote the use of innovative research methods to achieve precision home visiting —identifying the ingredients of home visiting that work best for specific families under certain circumstances. This approach has four key hallmarks:

  1. Focus on active ingredients, rather than complex models: Most home visiting models combine many ingredients to achieve diverse outcomes. These ingredients might or might not have a strong evidence base. HARC focuses on ingredients that, if found effective, can be adopted across relevant models to hasten the scale up of what works.
  2. Broad-based partnerships: Each stakeholder group brings a unique and vital perspective to home visiting. HARC brings together scientists, practitioners, community, and policy makers to partner in defining and testing specific ingredients to strengthen and broaden impacts.
  3. Explicit definitions and measurement: Understanding what specific ingredients work, for whom, requires explicit definition and measurement of ingredients, outcomes, mediators, and possible moderators of impacts. HARC’s approach embodies specificity in definition and measurement.
  4. Efficiency in testing ingredients: Many new research designs, such as adaptive trials and rapid cycle techniques, can accelerate our learning of what works, for whom.

HARC seeks abstract submissions that describe how current home visiting research is aligned with one or more of the above hallmarks of innovation toward precision home visiting. For instance, an abstract could describe how a research study is being designed to test active ingredients of an intervention. Abstracts do not necessarily have to be about completed research—we welcome any research-in-progress that aligns, or is being designed to align, with these hallmarks. We also encourage abstracts that will stimulate discussion and can create an interactive atmosphere.

HARC staff will offer technical assistance sessions to help presenters prepare their presentations to align with meeting content and themes. Presenters will also be reimbursed for one night’s hotel stay at the Grand Hyatt Washington.

Abstracts will be reviewed based on the following criteria:

  • Alignment with the hallmarks of precision home visiting
  • Potential of the presentation to contribute to advancing precision home visiting

Abstracts should be emailed to by September 30th, 2018 at 11:59pm EST. They should include the following information:

  • Presenter name, title, affiliation, email address, phone number
  • Names of any coauthors
  • Abstract text (500 words)

Please contact the HARC Coordinators at with any questions.

The Eighth National Summit on Quality in Home Visiting Program will be held on January 30th-February 1st, 2019. Registration for the Summit is separate from registration for the HARC Meeting, although organizers of both meetings are working together to align meeting content.
