The St. Louis Personality and Aging Network (SPAN) study initially focused on collecting information about personality and psychosocial measures but has since expanded to examine connections between personality and a multitude of measures of mental, cognitive, and physical health.
In 2016, the SPAN study expanded to investigate the children and grandchildren of our participants. This extension of the study is referred to as the St. Louis Personality & Intergenerational Network (SPIN) study. From our work with our original participants, we have found that certain personality, psychosocial, and biological factors affect health in later life. However, we suspect that these factors transcend generational boundaries to influence the health and well-being of subsequent generations. Therefore, in the SPIN study, we are attempting to determine how these variables are transmitted across generations. It is our hope that this research will shed light on how health disparities arise and are “inherited” by future generations, particularly the proliferation of racial health disparities.
