Follow Up

SATSA was started with a survey in 1984, and eight additional waves were conducted in 1987, 1990, 1993, 2004, 2007, 2010, 2012 and 2014. The questionnaire was initially sent to all twins from the Swedish Twin Registry who were separated at an early age and raised apart. There was also a control sample of twins who were raised together.

From 1986 to 2014, there were ten waves of an in-person testing (IPT) component for pairs who were over 50 years of age and had both responded to the initial questionnaire.
