ABSTRACT
Farrington (1978) found that there was significant continuity in aggressiveness over time in a sample of London males. Teacher-rated aggressiveness at age 8 predicted self-reported violence at age 18. The extensive reviews by Olweus (1979, 1980, 1984a) show that these results are not untypical. In 16 surveys covering periods of up to 21 years, the average stability coefficient (correlation) for male aggression was .68. Further, this average stability coefficient decreased linearly with the time interval, according to the following equation: https://www.w3.org/1998/Math/MathML"> y = .78 − .018 x https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203771693/e7b7124c-313e-4b8c-a90b-2a6d7ed0000f/content/math_1_B.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/>
