Hi Peter, 1. 5= Yes, they have met DSM4 criteria for Alcohol Dependence at some point over their lifetime (not necessarily at time of SSAGA screen). 1= No, they have never met DSM4 criteria for Alcohol Dependence at any point over their lifetime. I will add the clarification to the data dictionary. 2. Note that the Alcohol Use 7 day retrospective data that the Total_Drinks_7days variable comes from was collected at the time of the MRI scanning visit. The SSAGA screen was done by phone close to the time of confirming study eligibility and consent, which could be weeks or months before the actual MRI scanning visit.

The data dictionary only says "Participant meets DSM4 criteria for DSM4 Alcohol Dependence", but I'm still wondering about two things: 1. It seems participants are scored as either "1" or "5". I'm assuming "5" means they do meet the criteria for dependence, and "1" means they do not, is this correct? 2. If true, the characteristics of this group of subjects look somewhat odd. More than a handful report having had 0 drinks in the last 7 days (from the "Total_Drinks_7days" measure). It seems unlikely that someone would not have drank anything recently but still meet the DSM-IV criteria for alcohol dependence. What could be the explanation for this? Missing data? Or does the SSAGA_Alc_D4_Dp_Dx include current or PAST history of dependence?
