This study investigated characteristics of daily life activity experiences and their relations to stress in early adolescence. A sample of 134 8th graders carried electronic watches programmed to signal 7 times a day for a week at random times and reported their daily life activity experiences when signaled. Boys spent 33% of their waking hours in schoolwork, 46% in leisure, and 21% in maintenance activities. Girls spent 32% in schoolwork, 43% in leisure, and the other 25% in maintenance. Both boys and girls experienced more positive affect, cognitive, and motivation during leisure, whereas more negative psychological states during schoolwork. The major stress was schoolwork-related. The stress was significantly related to objective and subjective experiences of daily life activity.
