SDEPR - Depression Module 
			
			
OVERVIEW

Information about the Graduate-Sibling Respondent's depression experience was
collected in the following manner:

        - In 2004, life-time experiences of depression have been asked to 
          Graduate-Sibling Respondents who were randomly selected to answer on
          alcohol consumption and depression experiences (ALCFLAG = 1).
     
        - The 2004 Graduate, Graduate-Spouse, Graduate-Sibling share 
          same depression module.  
        
        - These depression modules are replicates of 1992 Graduate depression 
          module.
