Substances and Choices Scale (SACS)

Substances and Choices Scale (SACS)

Introduction

Alcohol and other drug (AOD) problems are a significant health issue for young people around the world and routine use of an AOD screening and outcome measurement instruments are recommended in all kinds of youth services. The Substances and Choices Scale (SACS) is an AOD screening and outcome measurement instrument that is simple to use, acceptable to young people and works well (is reliable and valid).

The SACS is a one-page pencil and paper self-report questionnaire for young people aged 13-18 years. It takes about 5 minutes to complete and is free of charge. It can be completed alone or in association with the young person's health or social agency worker. It is structured in a similar format to the Strengths and Difficulties Questionnaire (SDQ) and the two instruments can be used together if a broader perspective on a young person's functioning is required. The SACS can assist in identifying young people at risk of AOD problems and guide future treatment or referral options. In addition it can measure outcome as young people progress through the treatment process.

The SACS has three sections.

  1. The first section records the number of occasions the young person has used a variety of substances in the last month.
  2. The second section measures both substance use related symptoms and substance related harm. Scoring this section yields the 'SACS difficulties score' from 0 to 20. This score can be used to screen or measure change through a treatment episode.
  3. The third section asks about tobacco use.

SACS Questionnaires

There are two SACS questionnaires and they differ slightly. During the development of the SACS, consultation revealed that some agencies and clinicians may be deterred from using the SACS because they didn’t want to expose young people to the names of potential illicit substances.

For this reason we created a community version of the SACS that lists a limited number of substances.

The clinical and community version of the SACS differ only in terms of the content of Section A. The SACS difficulties score (Section B) is the same in both versions thus the psychometric properties of each version are the same.

SACS Clinical Questionnaire

The SACS Clinical questionnaire prompts the young person about their use of a wide range of substances and provides spaces for them to record "other drug use":

We recommend use of the clinical version of the SACS. 

SACS Community Questionnaire

The SACS Community questionnaire prompts the young person about their use of alcohol and cannabis only, but has spaces for the young person to record "other drug use".

SACS Information sheets

If administering the SACS you should spend some time discussing the process with your clients. This usually includes discussing the reasons for completing the SACS, issues related to confidentiality and how information from the questionnaire will be interpreted and used to plan and monitor treatment.

SACS Young Person Information sheet

The information sheet can be attached to the SACS to assist with this, but it is not a substitute for provision of proper informed consent.

SACS Clinician guide

The SACS Clinician Guide provides information about how to score and interpret the SACS. 

The SACS as a brief intervention - SACS BI

Whāraurau has developed a brief intervention for use in primary care settings called the SACS ABC. General information about SACS ABC can be accessed on the Screening & Assessment webpage that has a number of resources and videos to support clinicians who have little or no experience in providing addiction interventions.


 

Brief interventions involve gathering information about a person's substance use, giving them the opportunity to reflect on their behaviour and providing them with feedback and advice about changing. Potential outcomes from a brief intervention include increasing a young person's awareness of risks, a change in behaviour leading to harm reduction or successfully engaging a young person into longer-term treatment.

Links to detailed guides to perform a brief intervention utilising the SACS are provided below.

The complete version is a fairly detailed introduction to the principles of AOD treatment (and the SACS Brief Intervention) for clinicians with limited AOD experience.

The abridged manual concentrates mainly on the SACS BI and is intended for clinicians with previous experience and training in AOD assessment and treatment.

The SACS Manual:
The SACS has been tested in 13-18 year-old males and females from a variety of ethnicities. It has very good reliability and validity, and can measure change over time. Young people report that it is easy to complete and not distressing. Clinicians like its ease of use and scoring. Two links below provide further information about its validity and reliability

Disclaimer
The Substances and Choices Scale (SACS) is available for use by researchers and not-for-profit health and social agencies that provide services to enhance the health and wellbeing of young people. It has been designed to be used by health workers who have an active and ongoing relationship with the recipient of the questionnaire. This is so that issues around confidentiality can be discussed, and so that appropriate mental health support can be accessed if required.
