At ages 12, 14, 15, and 16, youths rated how well their parents monitored them by how well their parents knew where they went after school, who their friends were, how they spent their money, where they went at night, and how they spent their free time. Ratings were 1=the parents “do not know”, 2=“know a little”, and 3=“know a lot.” At ages 12, 14, and 15, parents’ monitoring ratings were made for parents as a unit. At age 16 ratings were made for each parent separately, and then were averaged together. Internal consistency ranged from .74 to .99, depending on the year, except at age 12, in which it was .42. Parental monitoring was averaged within time frame.
