Quasi-Experimental Designs

We can lead you in creating and conducting quasi-experimental designs.

One of Philliber’s key strengths is in determining valid comparison populations and appropriate strategies for analysis of these groups. Philliber has performed nationally recognized randomized control trials as well as numerous quasi-experimental designs. These include comparison studies, longitudinal comparison designs, and comparisons to publicly available data. We are familiar with propensity scoring methods for the creation of well-matched comparison groups in non-randomized designs.

A few select recent or key quasi-experimental evaluations include:

AmeriCorps Legal Advocates of Massachusetts

Philliber initially had a brief contract with the AmeriCorps Legal Advocates of MA (ALA-MA) to design an outcome and impact (quasi-experimental) evaluation plan which follows the AmeriCorps guidelines for documenting evidence. ALA-MA uses recently graduated attorneys to provide brief service and full representation for low income individuals and families facing eviction. In 2019, Philliber received an additional contract to implement the evaluation approved by the Corporation for National and Community Service that administers AmeriCorps.

Carrera in Schools (Carrera Social Innovation Fund), Children’s Aid Society/ True North Fund

Children’s Aid Society used a four-year grant from the True North Fund, a partnership of the Edna McConnell Clark Foundation and the Social Innovation Fund, to strengthen and test the effectiveness of the CAS-Carrera in-school program model. This model was one of only nine awarded funds. Philliber used a quasi-experimental design to evaluate the program from 2011 through 2015.

Maine Family Planning, Anonymous funder and the Family Planning Association of Maine

The Maine Family Planning project documented the implementation of primary care services in a family planning clinic in rural Maine and subsequent changes in patient and clinic-level variables as the clinic moved toward certification as a patient-centered medical home. The evaluation was a quasi-experimental design using two family planning clinics with no primary care that served as comparisons to family planning clinics with primary care. The research drew on both quantitative and qualitative data from a patient surveys, staff and administrator interviews, and clinic financial reports, as well as extensive gleaning of clinical and billing data directly from the electronic medical record system. A related case study on the process of transforming a family planning clinic into a level three patient centered medical home was completed in summer 2016.

Practice Makes Perfect, The Heckscher Foundation for Children, Practice Makes Perfect

Practice Makes Perfect is a multi-site summer learning loss prevention program in public schools in New York City. The evaluation used a quasi-experimental design, drawing on de-identified comparison data from well-matched schools. Data sources included surveys of students, teachers, parents, and principals; teacher observations; standardized testing data; and school year academic data from the New York City Department of Education.

Teen Outreach Program, Planned Parenthood of South Florida and the Treasure Coast/Children’s Trust Fund

Teen Outreach Program is a nation-wide model adolescent teen pregnancy prevention program focusing on the prevention of course failure, school suspension, school drop-out, and teen pregnancy. Philliber used a quasi-experimental design to evaluate the program in two Miami schools from 2012 through 2015.

Up2Us Coaches Across America, Up 2 Us Sports

U2UC trains AmeriCorps volunteers to implement sports-based youth development practices at a community-based organization. The coaches use these practices to engage youth in sports and mentoring activities designed to increase physical fitness and high impact attributes such as self-awareness, situational awareness, and social confidence, among others. The evaluation was a quasi-experimental, mixed methods outcomes evaluation that compared a sample of program students with a well-matched comparison group on target outcomes. A process evaluation supported the outcomes evaluation by examining the success of the strategies used to deliver the program, such as training, recruitment, and program delivery. The evaluation was conducted in New Orleans and Chicago.
