Using longitudinal data from a sample of 369 Finnish adolescents, the authors examined whether problems in social functioning in young adulthood were interrelated and accumulated, and analyzed processes that may lead to cumulative problems. The log-linear modeling showed that an unstable career line of men at age 26 was related to poor social relations, a poor financial standing, drinking problems, and criminal arrests; for both sexes, drinking problems and criminal arrests were interrelated. At a personal level, the authors analyzed male patterns of problems in social functioning and pathways resulting in patterns of social functioning. The pathway leading to an unstable career, criminal arrests, and drinking problems among men included aggressiveness at age 8 and problems in school adjustment and in the family at age 14.
