Effort-reward imbalance for learning is associated with fatigue in school children.

We examined relationships among fatigue, sleep quality, and effort-reward imbalance for learning in school children. We developed an effort-reward for learning scale in school students and examined its reliability and validity. Self-administered surveys, including the effort reward for leaning scale and fatigue scale, were completed by 1,023 elementary school students (grades 4-6) and 1,361 junior high school students (grades 7-9) at the end of 2006.
