Psychosocial concomitants of biological maturation in preadolescence
Abstract:
The authors studied 8 sets of healthy twins, ranging in physical maturity from prepubertal to late pubertal, and their parents to assess psychological changes in early adolescence. Interview and questionnaire data suggested that self-doubt, avoidance of responsiblity, resentment of parents, and anxiety about social relationships peaked in early puberty; emotional upset peaked in early puberty to mid-puberty. The results support a hypothesis of phase-specific psychosocial regression correlated with the biological onset of puberty. Children in all pubertal stages were shifting their interests away from parents and toward peers.
