The Cookpad home-cooking survey was included as a module within the Gallup World Poll in 2022. Since 2005, the World Poll has regularly surveyed people in more than 160 countries using mixed methods of telephone and face-to-face interviewing. In a typical year, the poll results represent more than 95% of the world’s population aged 15 and older, using randomly selected, nationally representative samples.
The questionnaire was translated into the major conversational languages of each country. The translation process started with an English, French or Spanish version, depending on the region. One of two translation methods may have been used. First, two independent translations were completed. An independent third party, with some knowledge of survey research methods, adjudicated the differences. A professional translator translated the final version back into the source language. Second, a translator translated into the target language. An independent third party with knowledge of survey methods reviewed and revised the translation as necessary.
Core Gallup World Poll question translations remain consistent over time. Any new question items were translated according to the Gallup World Poll’s quality procedures. Interviewers were instructed to follow the interview script and were not allowed to deviate from the translated language.
