This study reports on stability and change in emotional and behavioral problems in young adults over a 2-year time span. A sample of 528 18- to 22-year-olds from the general population was assessed using the Young Adult Self-Report (YASR) on two occasions. Stability coefficients for the total problem score of the YASR were 0.63 for males and 0.75 for females. Forty-nine percent of the subjects who were initially classified as deviant were still deviant at follow-up. Of all YASR syndromes, the highest stability was for the Anxious/Depressed scale.
