A Critical Review of Moderation Analysis in Tourism and Hospitality Research Toward Robust Guidelines

Purpose: This article proposes guidelines to (i) develop moderation hypotheses, (ii) assess moderators using the multigroup analysis (MGA) and interaction effect approaches, and (iii) interpret the results of moderation analysis in tourism and hospitality research. Design/methodology/approach: Through a review of 600 articles published in top tourism and hospitality journals from the year 2016 to 2020, and reviewing the literature related to moderation analysis, this study identifies key issues in different steps of moderation analysis and proposes robust guidelines to aid future research. Findings: The results of the systematic review uncovered some key issues in different steps of moderation analysis, such as hypothesis development, moderation assessment, and results interpretation. The findings emphasized the typical methodological misconceptions and improper practices for moderation analysis. Implications: Moderation analysis is of great significance to the advancement of theory, and its application has increased significantly in recent years. However, many studies appear to have a limited understanding of moderation analysis and follow questionable practices regarding (i) hypothesis development, (ii) moderation assessment, and (iii) results interpretation, thus leading to suspicious conclusions for theory advancement. By highlighting these methodological issues, this article provides robust guidelines for moderation analysis, which is of great theoretical and methodological significance to the academic research in tourism and hospitality. Originality/value: As one of the first study to provide robust guidelines for moderation analysis, based on a critical and systematic review of papers published in top tier journals in tourism and hospitality and the latest developments on moderation analysis in the wider literature, this article has important theoretical and methodological significance for the academic research in tourism and hospitality as well as general social science disciplines.
