In multinational surveys, mixed-mode administration modes (i.e., combining online and by paper-andpencil administration) are increasingly used. To date, no studies have investigated whether measurement equivalence exists between online data collection and data collection using the conventional paper-andpencil method in organizational surveys which include a large number of countries. This paper examined the measurement equivalence of a truly global organizational survey across online and paper-and-pencil survey administrations. Data from an organizational survey in 16 countries (N=52,461) across the globe were used to assess the measurement equivalence of an organizational climate measure within

each country in which the survey was administered. The empirical data provided strong indications which support the measurement equivalence of the multi-item survey instrument across online and paper-and-pencil surveys in virtually all countries in which the survey was conducted. These findings suggest that merging data obtained through online and paper-and-pencil data administration in a particular country is legitimate as no evidence was found for differential effects across both modes of data collection.
