Objectives

Narrative objectives1

The objective of this study is to develop a new standardized evaluation tool, the Japanese version of KaTid-Child (KaTid-C-J), for quantitatively assessing Time Processing Ability (TPA) across developmental stages, adapted to the cultural and social environment of Japan. Specifically, the aim is twofold: first, to design an original tool reflecting Japanese lifestyle and cultural characteristics; and second, to calculate standard TPA values for typically developing children aged 5 to 10 years. The Swedish KaTid-Child was referenced in the design of the original tool. The establishment of these standard values will serve as a foundational framework for comprehensively supporting the development of children's time concepts, facilitating problem-solving in time perception, time orientation, and time management, and promoting social participation.

Other related information

This cross-sectional observational study involves typically developing children aged 5 to 10 years. Participants will undergo a single assessment (with an approximate duration of 45 minutes) using the Japanese version of the KaTid-Child (KaTid-C-J) scale. The provision of new treatments or interventions is not a component of the present protocol. The assessment results will be used to calculate standard values for Time Processing Ability.
