1. Chapter 19 Methods Appendix GAIN Coordinating Center (11/21/2012). Normal, IL: Chestnut Health Systems. November 2012. Available from www.gaincc.org/slideswww.gaincc.org/slides Created for: Substance Abuse and Mental Health Services Administration’s (SAMHSA) Center for Substance Abuse Treatment (CSAT) under contract number 270-2012-00001

2. 2 Methods Appendix  This section provides an overview of methodological issues including: –Administration times –Follow-up rates, –Months to last follow-ups, –Number of follow-ups, –Instrument fidelity.

3. 3 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.

5. 5 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.
