Research Methods Used in Evidence-Based Design: An Analysis of Five Years of Research Articles From the HERD Journal

Abstract

Objective: This study aims to analyze research methodologies from 157 research articles published in this journal in the last five years (2016–2020). Background: Health environments research is comprised of research covering many topics and from various disciplines worldwide. No systematic study exists to uncover themes in evidence-based design (EBD) research concerning the types of research published, people engaged in research, and the research methods employed. Understanding the nature of health environment research performed can help researchers, practitioners, and students situate their work within an EBD research structure. Methods: Case study research was used to analyze 157 articles published in the Health Environments Research & Design Journal devoted to EBD and research. Secondary data were extracted to capture research methods from health environments studies and then analyzed to identify themes. The design and outcome categories were structured around and the Center for Health Design’s (CHD) Knowledge Repository with origins to Ulrich et al.’s Evidence-Based Design Framework. Results: Findings are reported on categories commonly found in empirical research articles: (i) key words, (ii) disciplines from authors, (iii) settings studied, (iv) populations studied or sampled, (v) research approach and study design, (vi) research strategies, (vii) data collection methods, (viii) data analysis procedures, (ix) design categories and variables, and (x) outcome categories and variables. Conclusions: The analyses highlighted the research methods most frequently used in health environments research. Findings revealed several inconsistencies across articles on key words and the framing of research methodologies. Results suggest that there should be a consistent and overarching research taxonomy with a set of acceptable terms for effective literature searches.
