Adolescent Twin Study
The MSUTR Adolescent Twin Study of Behavioral Adjustment and Development is a study of 206 same-sex male, 312 same-sex female, and 120 opposite-sex twins between the ages of 10 and 16 years old. The primary purpose of the study was to investigate genetic, environmental (e.g., teasing by peers, parent-adolescent relationships), and neurobiological (i.e., gonadal hormones) risk factors for disordered eating, antisocial behavior, mood, attention/hyperactivity problems, and temperament during early adolescence. In particular, this study aimed to understand whether these psychological characteristics are related to gonadal hormone levels during puberty, whether relationships amongst these factors are influenced by genes, and whether gene x environment interactions influence their development.
