Common method bias in research designs using self-report tools: literature overview and recommended remedies

One of the most discussed and controversial methodological and statistical issues that concerns empirical survey-based research is common method bias, which may occur when the data for the predictor and criterion variables come from the same person using the same response method. Uncontrolled method variance may produce biased estimates of the reliability and validity of the examined constructs and erroneous parametric estimates of the relationships between two constructs. The aim of the study is the literature overview on the concepts of common method bias and variance. The 143 articles that derived from the advanced search of relevant studies in four databases demonstrated the main thematic sections of the present study. Classical test theory was used to explain the sources of measurement errors and the effects of common method variance. Subsequently, the prevailing procedural and statistical remedies for controlling common method variance were described. The potential effects of common method variance on self-report research are complex and difficult to understand, but despite the debate about its nature and extent, researchers from psychology and social or organizational disciplines should take steps to minimize method bias. © 2022, National Documentation Centre.
