A trajectory defined by threetime-ordered events was offered as a useful adjunct to building a development theory aboutantisocial behaviors. A sequence was defined with significant linkages between antisocialchildhood behavior and early arrest and between early arrest and chronic offending. The majorityof chronic offenders traveled through all three events in the sequence. Each event in the sequenceshared a common process of disrupted family process plus frequent family transitions andmarked social disadvantage. The findings support the hypothesis that the process that leads toantisocial behaviors at grade four may also maintain the entire sequence. The level of disruptedprocess at initiation and a time-based measure of involvement with deviant peers predicted whichindividuals moved forward in the sequence and which did not. The findings are consistent withthe idea that the majority of chronic offending juveniles follow a trajectory that can be explainedby a single theory.
