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.

Famous quotes containing the words adolescent, twin and/or study:
“While the onset of puberty can vary by as much as six years, every adolescent wants to be right on the 50-yard line, right in the middle of the field. One is always too tall, too short, too thin, too fat, too hairy, too clear-skinned, too early, too late. Understandably, problems of self-image are rampant.”
—Joan Lipsitz (20th century)
“We live under continual threat of two equally fearful, but seemingly opposed, destinies: unremitting banality and inconceivable terror. It is fantasy, served out in large rations by the popular arts, which allows most people to cope with these twin specters.”
—Susan Sontag (b. 1933)
“The traveller who has gone to Italy to study the tactile values of Giotto, or the corruption of the Papacy, may return remembering nothing but the blue sky and the men and women who live under it.”
—E.M. (Edward Morgan)
