The purpose of this article was to study the characteristics of apathy within primary and secondary school students and the differences between two groups in terms of apathy. In Study I, fifty questions selected from previous studies were administered to 569 primary school and 602 secondary school subjects. Through the statistical analyses, five similar subcategories were found for both primary and secondary school subjects. In Study II, an elaborated version of the questionnaire was constructed, using four items from each subcategory, and was administered to 1721 primary and 1396 secondary school subjects. A similar structure as found in Study I resulted, suggesting that the structure was reliable. Among the subcategories, primary school subjects scored high in “inadaptability to study” while the secondary school subjects scored high in “declination of motivation, and physical inadaptability”. Correlations between subcategories were higher for secondary school subjects than for primary school subjects, suggesting that apathy was becoming more general across the subcategories in elder subjects.
