Formal research

The KIT project is a longitudinal study of children in Taiwan that follows their development from birth to eight years of age. The implementation of the project consists of four phases. Two cohorts of children participated at the start of Phase I: (1) 3-month-old infant cohort (or KIT-M3): children aged 3 months, 6 months, or 12 months; (2) 36-month-old child cohort (or KIT-M36): children aged 3 or 4 years. In addition to face-to-face individual test and observation, measures were taken on many facets of their development, such as health, cognition, language, as well as social-emotional development, physical/motor development, and family/child care experiences.

In Phase II, the project kept collecting the data of the study children. Also, the research team self-developed an instrument exclusively for children aged 6 to 8 to evaluate their development, family/school environments, and family/school experiences. Data collection will continue in Phase III and Phase IV. At the end of Phase IV, the data of two cohorts of child participants from their birth to eight years of age will be completely collected.
