The 34th wave of the main interview was underway when Hurricane Katrina struck the Gulf Coast on August 29, 2005 causing devastation along the coast of Louisiana, Mississippi and Alabama. With a special supplement from the National Science Foundation, the Department of Homeland Security (PI Stafford, No. 0649543), and the National Institute on Drug Abuse (PI Galea No. 017642), 555 PSID families living in these three states at that time received a 20-minute module assessing their exposures and experiences with Hurricane Katrina as part of the 2007 main interview.   As described in the Documentation and Questionnaire for PSID 2007 Hurricane Katrina Supplement, the module contains data characterizing (a) exposure to the hurricane, including personal and property damage to one’s home, property, business, (b) evacuation experiences, (c) reactions to the event and to the rescue/recovery efforts (d) mental health, including substance use, dependence, and abuse, depression, PTSD, service utilization (e) social supports and social networks general functioning after the hurricane. These data can be used under restricted contract in conjunction with the main PSID data to develop analytic models to study how pre-existing socioeconomic characteristics and functioning prior to Katrina may affect the impact of Katrina, and return to baseline functioning.
