Development's tortoise and hare: Pubertal timing, pubertal tempo, and depressive symptoms in boys and girls. [PDF]

Developmental Psychology, 2010
Although the sequence of pubertal maturation remains consistent across most individuals, the timing and tempo of development fluctuate widely. While past research has largely focused on the sequelae of pubertal timing, a faster tempo of maturation might also present special challenges to children for acclimating to new biological and social milestones.

Pubertal timing predicts adult psychosexuality: Evidence from typically developing adults and adults with isolated GnRH deficiency.

Psychoneuroendocrinology, 2020
Evidence suggests that psychosexuality in humans is modulated by both organizational effects of prenatal and peripubertal sex steroid hormones, and by activational effects of circulating hormones in adulthood.

Pubertal timing and educational careers: a longitudinal study

Annals of Human Biology, 2004
Pubertal timing is related to several dimensions of adolescent development. No studies concern its associations with educational careers.To investigate whether pubertal timing predicts attained educational level and how school achievement, educational track and sociodemographic background in adolescence mediate this relationship.Survey data (1981, 1983,

Pubertal timing and self-harm: a prospective cohort analysis of males and females

Epidemiology and Psychiatric Sciences, 2020
Aims Early puberty is associated with an increased risk of self-harm in adolescent females but results for males are inconsistent. This may be due to the use of subjective measures of pubertal timing, which may be biased.
