Administration Times ‘Core Only’ administration refers to records where the
participant was asked only the required GAIN items and none of the optional items.
‘Core + Optional’ (Full) administration refers to records where the participant was asked all required and optional GAIN items. This version includes recommended and treatment items for a broader clinical picture.
‘Total’ indicates the combination of both the records that used a core with the records that used the full.
Approximately 8% of cases could not be designated as a Full or a Core only administration.
Less than 1% were missing data on interview duration.

Valid N for Core and Optional Items
The number of cases available for analysis will vary depending upon whether the item of interest is a an optional or required (Core) item.
The following slides show the number and breakout characteristics of cases available when the item of interest is Optional or Core.– Optional items: Only those that opted to fill out a full version of the
GAIN will have valid answers to optional items, so optional items will have a lower number of valid responses.
– Required/Core items: Every record should have a valid answer for a required item, so core items will include all records in the SAMHSA/CSAT Data Set.
