The Contextual and Individual Linguistic Diversity Questionnaire (CILD-Q) was developed to capture a previously under-studied aspect of multilingualism, contextual linguistic diversity (CLD), which includes active and passive exposure to languages via the sociolinguistic context. CLD considers the environment in which individuals use and perceive language and includes ambient linguistic information gained from environmental cues. The CILD-Q was originally developed from South African and UK samples and comprises three factors: Multilingualism in Context, Multilingualism in Practice, and Linguistic Diversity Promotion. The current study investigates the factor structure of the CILD-Q in the highly multilingual and multi-ethnic context of Singapore. After conducting both confirmatory and exploratory factor analyses, five items from the original questionnaire were removed and while three factors did emerge, they were somewhat different from the original ones. The factors found in this study are best labelled as Switching in Context, Switching in Practice, and Linguistic Diversity Promotion. We discuss possible reasons why the CILD-Q in its original form may not be as suitable in Singapore and why the updated factors provide a better fit, and explore the possibility that the widespread and uniform practice of multilingualism may contribute to low variability in CILD-Q responses.
