At Altered High we use the SACS questionnaire (Substances and Choices Scale) as a way to measure progress for young people going through the service (outcome measurement). It can also be used to identify potential problems (screening). More information about the SACS is available at www.sacsinfo.com.
The SACS questionnaire can be used as a starting point for doing a Brief Intervention. This is a short bit of treatment that can be effective in minimising harm and enhancing the chances of a young person engaging in longer term treatment. The SACS Brief Intervention is a step by step guide to doing a brief intervention using the SACS. It is also on the SACS website here.
Altered High has made a video which demonstrates a clinician doing the SACS Brief Intervention with a young person. You can watch it on YouTube here.
