What does the Substance Dependence Severity Scale (SDSS) assess?

The Substance Dependence Severity Scale (SDSS) is specifically designed to evaluate the severity of substance dependence, which includes alcohol and other drugs. This scale allows practitioners to quantify the degree of an individual’s dependence on substances by examining various aspects such as patterns of use, behavioral issues, and the implications of dependence on the individual's life.

Option A is correct because the SDSS focuses on assessing the severity of dependence, particularly relating to alcohol and other substances. This assessment helps in understanding the intensity and impact of the dependence, which is crucial for determining the appropriate treatment plan.

The other options do not accurately reflect the main purpose of the SDSS. While the scale may indirectly touch on aspects of mental health and social behavior, its primary goal is not to analyze the effects of alcohol on mental health or to investigate social drinking habits. Additionally, legal consequences are not a focus of the SDSS; rather, the scale is concerned with measuring dependence severity rather than the legal implications of substance use. Thus, the emphasis is firmly on substance dependence rather than broader social or legal contexts.
