Data is planned to be collected in three waves: 2016-2017, 2018-2019, and 2020-2021, accordingly. Our goal is to reach about 800 twins plus family members in the Twin Family Study and about 2000 individuals plus peer raters in the Age Groups Study. We capture narrow-sense personality traits (HEXACO-PI-R and BFI-2), self-related concepts (e.g., RSES, EI4, ASKU, SWLS and HSWBS), motives, goals, and interests (UMS, AI and SIT), moral foundations und values (MFQ-21 and PVQ-57-RR) as well as religiousness (Z7). In addition, we ask for major life events that were experienced between the measurement occasions. The kick-off of the research project was in autumn 2015 at Bielefeld University. Between April 2017 and the end of 2018, SPeADy was affiliated with an additional university – the MSB Medical School Berlin. Because Christian Kandler was offered a full professorship at the University of Bremen, SPeADy is located there since January 2019.
