What is the primary purpose of screening in the context of alcohol and drug use?

The primary purpose of screening in the context of alcohol and drug use is to evaluate psychological and physiological signs of substance use. Screening serves as an initial step in examining an individual’s possible substance use issues, helping to identify those who may benefit from further assessment or intervention. This process involves gathering information regarding the individual's substance use patterns, mental health status, and related factors. By assessing these elements, professionals can gain insights into the severity and nature of the individual's substance use, which is crucial for determining appropriate next steps in care or treatment.

The other options relate to different aspects of the treatment process but do not directly represent the fundamental purpose of screening. For instance, while treatment recommendations may follow an assessment, they are not the immediate focus of screening. Similarly, ongoing assessments during treatment and finalizing admissions pertain to distinct stages in the treatment process that occur after the initial screening phase. Thus, evaluating psychological and physiological signs is the essential function of screening in identifying those who may need further help with substance use.
