2. Background  The Global Appraisal of Individual Needs (GAIN) is a family of instruments ranging from screeners to full standardized biopsychosocial.  Over the past decade it has become one of the most commonly used standardized instruments in adolescent substance abuse treatment and research.  Its strengths include - mapping onto common standards for diagnosis, treatment, planning, placement, and performance monitoring; - clear training, feedback and certification standards to support workforce development and interpretation; - a large number of investigators conducting primary studies, methodological and secondary analyses with it; - a large pooled data facilitating comparisons across studies, sites and evidenced based practices; and the introduction (in 2008) of a new web based infrastructure to support use across multiple settings.

3. Purpose of this panel  The biggest single complaint about the GAIN is the time it takes to administer (90-120 minutes for a full GAIN) and the cost (both in terms of training and staff time to administer).  This provides an overview of the progressive approach to assessment we are trying to develop and then talk about three specific efforts we are working on to reduce the duration and cost of assessment. 1. Introduction of the GAIN Short Screener (GSS) 2. Developing a newer and more efficient version of the GAIN –Quick (GQ) 3. Developing a computer adaptive testing (CAT) version of the full GAIN

4. Progressive Assessment Approach  Screening to Identify Who Needs to Be Fully “Assessed” - Focus on brevity, simplicity for administration & scoring - Needs to be adequate for triage and referral  Quick Assessment for Targeted Referral - Assessment of who needs a feedback, brief intervention or referral for more specialized assessment or treatment - Needs to be adequate for brief intervention  Comprehensive Biopsychosocial - Used to identify common problems and how they are interrelated - Needs to be adequate for diagnosis, treatment planning and placement of common problems  Specialized Assessment - The bio-psycho-social may identify areas where additional assessment by a specialist (e.g., psychiatrist, school counselor) may be needed to rule out a diagnosis or develop a treatment plan or individual education plan  Program Level Assessment - For program management, evaluation, and planning

6. Overview of the GAIN-SS  A 3- to 5-minute screener  Used in general populations to identify or rule-out clients who will be identified as having a behavioral health disorders on the 60-120 min versions of the GAIN  Easy for use by staff with minimal training or direct supervision  Provides a measure of change  Designed for self- or staff-administration, with paper and pen, computer, or on the web  Translated by collaborators into several languages including French, Japanese, Portuguese, and Spanish so far

8. Recency Response Set  Recency of 20 problems rated as past month (3), 2-12 months ago (2), more than a year ago (1), never (0)  Combined by cumulative time period as: - Past month count (3s) to measure of change - Past year count (2s or 3s) to predict diagnosis - Lifetime count (1s, 2s or 3s) as a measure of peak severity.  Can be classified within time period low (0), moderate (1-2) or high (3)  Can also be used to classify remission as - Early (lifetime but not past month) - Sustained (lifetime but not past year)

12. Some important caveats…  Does not focus on low level problems (e.g., any use) to minimize false positives  Designed to have 90% sensitivity and is only self report, which means it does miss some and that clinicians should still be able to over ride on a case by case basis  Inclusion of lifetime measures provide checks against temporary phenomena (e.g., being in a controlled environment) and to drift when used to measure change (e.g., lifetime use should never go down)  Just a screener, not a full assessment

18. Rapidly Spreading  State or Provincial wide implementation in multiple states (ID, CT, LA, MI, MN, NH, NV, OR, SC, WA, WI) and provinces (BC, ON, QU) in one or more large systems (adolescent or adult addiction treatment, mental health, welfare, juvenile or criminal justice, Student or Employee Assistance Programs),  Used by SAP or EAP in Brazil, Canada, Japan, Mexico, United States and being translated for use in China.  Most have relied on paper and pencil administration or installed into their own information system – but then do not get reports.  There is a software template available, but its use still requires adaptation to one’s own system  Assessments.com is one of the one of the first commercial vendors to offer a web based version of the GAIN SS for both system and individual level user.
