One year later, ten ofthese subjects had scores greater than 16 (the non depressed-depressed group), and 87 had scores less than 16 (the non depressed-nondepressed group).

For the remainder ofthe analysis, subjects with CES-D scores greater than 16 both at the time of the first study and one year later were clas sified as having persistent depression (N = 11).
