This study develops and validates a multiple intelligence test for emerging adults in the UK, addressing limitations of traditional intelligence tests. Drawing on Gardner's theory, the test assesses various domains including interpersonal, kinesthetic, musical, and naturalistic intelligences. Results from a diverse sample of 124 emerging adults show a robust factor structure aligned with Gardner's framework, demonstrating high reliability and concurrent validity with established measures. Discriminant validity analysis indicates effectiveness in distinguishing demographic factors. This study contributes to a more inclusive approach to intelligence assessment, recognizing the complexity of human cognition. Future research should validate the test across diverse populations, advancing our understanding of intelligence and enhancing assessment practices.
