A Scoping Review on Perception-Based Definitions and Measurements of Corruption.

Studies on perceptions of corruption have grown in recent years but are still struggling with several conceptual and measurement issues. This scoping review provides an analysis of the peer-reviewed literature on perception-based corruption. From a total of 1,374 articles surveyed, 90 ultimately met inclusion criteria. We found two main quantifiable trends when exploring our sample: publications in high-impact journals were slow in addressing perception-based corruption, and perceptions of corruption are of interest not only to political science and sociology but to other disciplinary traditions. In more qualitative terms, we observe that the explicit or implicit definitions of "corruption" behind these studies tend to fall into two categories: corruption as a "Deviant Process" or as a "Deviant Outcome," while measurements can be typified in a two-dimensional scheme: "Sociotropic" vs. "Egocentric" and "Generic" vs. "Specific." Most measurement approaches surveyed tend to use a "deviant process" definition, whereas the measurement of corruption as a "deviant outcome" still lacks development. This might represent a challenge for future research focusing on the social understanding of corruption in various contexts (administrative, organizational, political, economic, legal, etc.).
