Identifying Relevant Methods and Study Designs for Investigating Health Equity in Implementation Science
This section gives a brief overview of methods and study designs that were used or recommended for use by investigators that integrate a primary or secondary focus on health equity in implementation science. It is not an exhaustive list and is meant to be a resource for people new to this research area. Following McNulty and colleagues’ guidance in “Implementation Research Methodologies for Achieving Scientific Equity and Health Equity,”1 we categorized methods and study designs in Table 4 into three paradigms: 1) research using existing data to assess health inequity and related factors; 2) research including populations experiencing health inequities; and 3) research focusing on addressing health equity. Some study designs and methods may apply to all the three research paradigms; while others may be more relevant to a single paradigm than others.

Analytic epidemiologic methods | Regression analysis to assess the association between social determinants of health and outcomes from IS studies; includes regression model, mixed effects model, moderated regression, and mediation analysis | Assess factors associated with health disparities or mechanisms that can explain them | Morgan et al., 20184 |
Agent-based modeling | Building computational models to simulate the actions and interactions between entities (called “agents”) of a complex system | Assess the likely impact of specific implementation strategies on reducing disparities |

Shelton et al., 20228
Ramanadhan et al., 20219 Allen et al., 202110 |
Community-based participatory research (CBPR) | A collaborative approach that involves community partners in all phases of the research process, aiming to increase local relevance and reduce health disparities11; CBPR adopted a variety of research methods, such as intervention mapping, transcreation, and implementation mapping | Understand the health equity-related issues in the local context and identify strategies or interventions to address these issues | Tomayko et al., 201912 |
Intervention mapping | A planning framework that “provides a systematic process and detailed protocol for effective, step-by-step decision-making for intervention development, implementation, and evaluation”13 | Provide guidance on how and when to use evidence, theory, and community-based participation during the implementation process | Holcomb et al., 202114 |
Implementation mapping | A systematic process, by extending intervention mapping, for planning or selecting implementation strategies 15 | Same as above | Ibekwe et al., 202216 |
Study designs: Paradigms 2 and 3 | |||
Hybrid effectiveness-implementation trial | A study design that “takes a dual focus a priori in assessing clinical effectiveness and implementation”, including three hybrid types I-III17 | Assess effectiveness and the implementation process and outcomes of interventions that address health disparities | Smith et al., 201818 |
Pragmatic non-randomized trial | Quasi-experimental study designs that compare effects of interventions between non-randomized intervention group and control group | Compare effects of implementation programs or interventions that aim to address health disparity in the clinical setting | Cykert et al., 202019 |
Sequential multiple assignment randomized trial (SMART) | A randomized experimental design for building time-varying adaptive interventions20 | Compare combinations of interventions and implementation strategies for underserved populations | Johnson et al., 201821 |
Mixed methods design | A study design that combines quantitative and qualitative research methods22 | Assess barriers and facilitators to the implementation of EBI or adaptation of implementation programs in underserved populations | Shelton et al., 202123 |
