Methodological coherence

Health Management Glossary

Research Methods

Definition. Methodological coherence is the degree to which the elements of a study, namely its research question, prior theory, philosophical stance, design, data, analysis and claims, are consistent with one another, so that each element is justified by the one before it and no claim goes beyond what the design can deliver.

Explanation

Coherence is a property of the relations between the parts of a study, not of any single part, so a study can be rigorous at every step and still be incoherent as a whole. The literature uses several overlapping labels with different emphases: methodological fit stresses the match between design and the maturity of prior theory (Edmondson & McManus, 2007), methodological congruence the match between methodology and philosophical perspective, and internal coherence the alignment of ontology, epistemology, axiology, methodology and methods (Palermo et al., 2021). In qualitative research, Morse et al. (2002) named methodological coherence the first strategy for verifying a study.

Typical incoherences include choosing a method before the question is clear, using quality criteria that contradict the study’s own paradigm, and drawing causal or policy claims from exploratory or cross-sectional designs. The statistical fit of a model is not the methodological fit of a study: good fit indices in structural equation modelling say nothing about whether the design suits its question and claims (Coherence in Research: An Introduction (101)).
