Welcome to the SPAN Lab!

Directed by Professors Ryan Bogdan, Patrick Hill, and Thomas Oltmanns at Washington University in St. Louis

The primary study being conducted in the SPAN lab is the St. Louis Personality & Aging Network (SPAN) study.  This study was launched in April of 2007 and it is being conducted by a multidisciplinary team of investigators who have substantial experience in personality, aging, and epidemiological studies.  It is a prospective, longitudinal study of the stability and impact of personality in later life.  The study examines connections among personality traits, physical and subjective health, social adjustment, and biological markers of immune system functioning in a sample of participants approaching the challenges of later life.  A primary goal of the SPAN study is to identify the extent to which personality and personality problems influence the ability to adapt successfully to important life transitions.

  1. i loved taking the lab tests, learned a lot about my self, the people who tested me were great

  2. Span has made me realize that despite age, I have value. Since starting Span, I have attended college where my emphasis is on Psych and English Writing. (Honors). I have been remote counseling several youths rescued from sex trafficking all of which have been diagnosed with C-PTSD. Amongst their issues are BPD, DID, and one diagnosed as a Clinical Lycanthrope. Ethics and legal requirements prevent me from disclosing more. This contact has produced a drive in me to do more, so I started a drive called OurHomeStead School Farm. More data can be seen in our web OurHomeStead.Farm
