The Chemical Use, Abuse, and Dependence Scale is best known for:

• A. Its utility in diagnosing depression
• B. Its utility in assessing substance abuse in mentally ill clients
• C. A method for predicting relapse
• D. A tool for measuring personality traits

Answer: (B)

This item is testing what the Chemical Use, Abuse, and Dependence Scale is used for in practice. This instrument is designed to assess substance-related problems specifically in people who have a mental illness. It helps clinicians gauge the extent of use, abuse, and dependence and to plan integrated treatment for clients with co-occurring disorders. It’s not a tool for diagnosing depression, predicting relapse, or measuring personality traits, which is why its best-known use is in evaluating substance abuse among mentally ill clients. In clinical settings, it supports screening and monitoring progress, guiding decisions about combined mental health and substance use interventions.
