Study goals
This study aims to quantify the actual effect size of the relationships between ego depletion and variables associated with consumer behavior, in order to consolidate and critically assess the robustness of the evidence available in the marketing literature.
Relevance / originality
Although ego depletion is a construct widely studied in psychology, no systematic quantitative synthesis focused on marketing and consumer behavior had yet been published in Portuguese, which underscores the originality and relevance of this work.
Methodology / approach
A meta-analytic review was conducted based on articles indexed in the Web of Science database. Initially, 1,001 manuscripts were identified, of which 89 met the inclusion criteria, resulting in 72 independent relationships and a total sample of 17,549 respondents.
Main results
Preliminary results indicate that ego depletion shows a significant, albeit small, association with variables such as education and age, while relationships with gender, professional performance, and organizational stability were not significant in the present sample.
Theoretical / methodological contributions
This work contributes by providing a first quantitative mapping of ego depletion in marketing and by paving the way for more comprehensive and refined future investigations.
Social / management contributions
The results offer insights for marketing strategies that take into account consumer vulnerability to decision fatigue, as well as highlight the importance of educational and organizational practices that minimize self-regulatory depletion.
