Pubertal maturation and the development of behavioural and emotional problems in early adolescence

Development of problem behaviour in early adolescence was predicted from ch ange in pubertal stage and timing of pubertal development. Parent-reported (Child Behavior Checklist) and self-reported (Youth Self-Report) problem be haviour, pubertal stage and life events were assessed twice from a communit y sample of nearly 1300 Dutch children, aged 10-12 years at T1 and 12-14 ye ars at T2. Pubertal change was a significant predictor of development in mo st parent-reported problems. Once initial differences in problems had been accounted for, the slower the progress in pubertal development, the higher the problem score at T2. Development of self-reported problems was independ ent of pubertal change, Pubertal timing predicted development of two parent -reported and three self-reported problem scales. Of the parent-reported pr oblems, early maturation was associated with a decrease in boys' social pro blems and attention problems. Late maturing increased girls' social problem s. Of the self-reported problems, early maturation was associated with an i ncrease in girls' withdrawn and delinquent behaviour. Late maturing increas ed boys' attention problems. We conclude that pubertal development has smal l but significant effects on the development of problem behaviour in early adolescence.
