Frequently Asked Questions (FAQ)

1. What is the difference between a substance abuse screening and an assessment?
A screening is a brief, preliminary step used to detect the potential for a substance use problem. Tools like the AUDIT or CAGE-AID are common screeners. If a screening is positive, a comprehensive assessment is then conducted. An assessment, like the ASI or one guided by ASAM Criteria, is a much more in-depth evaluation that diagnoses a substance use disorder, determines its severity, and informs a treatment plan.

2. Who can administer these substance abuse assessment tools?
This varies by the tool. Simple screening tools are often designed for use by a wide range of professionals, including primary care physicians, nurses, social workers, and school counselors. Comprehensive assessment tools like the SASSI or ASI require administration by trained and often licensed clinicians, such as psychologists, licensed professional counselors (LPCs), or certified addiction specialists, to ensure accurate interpretation.

3. Are substance abuse assessments confidential?
Yes. When conducted in a clinical setting by a healthcare provider, the results of a substance abuse assessment are protected health information (PHI) under laws like HIPAA in the United States. Information can only be shared with the patient's explicit consent, except in specific situations where there is a clear danger to the individual or others.

4. Can I take a substance abuse assessment online by myself?
While some websites offer self-assessment questionnaires, these are not a substitute for a professional evaluation. They can be a helpful first step to gain personal insight, but they cannot provide a formal diagnosis. A true assessment involves a conversation with a trained professional who can interpret the results in the context of your unique life circumstances to recommend the right level of care.
