The 5-minute GAIN-Short Screener (GAIN-SS) is designed primarily for 3 things: First, it serves as a screener in general populations to quickly and accurately identify clients (also known as patients, respondents, or research participants) whom the full 1.5 to 2-hour GAIN-Initial would identify as having 1 or more behavioral health disorders (e.g., internalizing or externalizing psychiatric disorders, substance use disorders, or crime/violence problems), which would suggest the need for referral to some part of the behavioral health treatment system. It also rules out those who would not be identified as having behavioral health disorders. Second, it serves as an easy-to-use quality assurance tool across diverse field-assessment systems for staff with minimal training or direct supervision. Third, it serves as a periodic measure of change over time in behavioral health. It is designed for self- or staff administration with paper and pen, on a computer, or on the web. It can be easily converted to a scannable form or incorporated into existing instrument batteries or systems. Versions in different languages (such as Spanish) are also available.
