Which of the following is the first of the 12 Core Functions of addiction treatment?

The first of the 12 Core Functions of addiction treatment is screening. This function is essential as it involves the initial process of evaluating an individual to determine if they have a substance use disorder and to identify their need for further assessment or treatment. Screening typically includes the use of standardized tools and questionnaires designed to gather information about the individual's substance use, behaviors, and any related issues.

Screening is a critical first step because it sets the stage for further evaluation and intervention. By accurately identifying those who may benefit from additional assessment and support, professionals can ensure that individuals receive the most appropriate level of care. This early identification is vital in the treatment process, as it helps to connect individuals with the necessary resources and services to embark on their recovery journey.

In terms of the other functions listed, while intake, assessment, and treatment planning are all essential components of the overall addiction treatment process, they follow screening in the sequence of actions taken when a client first seeks help. Each function builds on the previous ones, but screening is where the process begins, making it foundational in the treatment of addiction.
