Presentation Transcript

### Chapter 19Methods Appendix

GAIN Coordinating Center (11/21/2012).

Normal, IL: Chestnut Health Systems. November 2012.

Available from www.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

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.

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.

Administration Times

SAMHSA 2011 GAIN Summary Analytic Data Set (n = 29,715)

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.

Summary of Psychometrics of Treatment

- Normative psychometric data and basic demographic information for GAIN scales and data sets (mean, N, standard deviation, Cronbach's alpha and intraclass correlations are available at http://www.gaincc.org/_data/files/Psychometrics_and_Publications/Resources/GAIN-I_Norms.xls
- This file is broken up into separate worksheets for all records, Adolescents (age 12-17), Young Adults (age 18-25), and Adults (age 18 and higher).
- Within each age category, demographics are presented first, followed by overall norms and ICC including across follow-up waves, then intake norms by each of the three main demographic categories of gender, race and age.

Accessing GAIN Data of Treatment

- Access to the de-identified pooled SAMHSA/CSAT data set is available through request.
- For more information regarding how to request data and what you will need please visit http://gaincc.org/analysis
- Summary of what is needed:
- Data Sharing Agreement (see DSA Decision Tree at http://www.gaincc.org/_data/files/Psychometrics_and_Publications/Analysis_Publication/DSA_Decision_Tree.pdf)
- A 1 - 3 page abstract (see Access training memo at http://www.gaincc.org/_data/files/Psychometrics_and_Publications/Analysis_Publication/Access.pdf)
