The Coping Behaviors Index measures which of the following?

The Coping Behaviors Index specifically focuses on measuring relapse prevention mechanisms. This index is designed to assess the various strategies and behaviors that individuals utilize to manage stress and avoid relapse into substance use. By identifying these coping behaviors, counselors can better understand their clients' strengths and areas that may require further support or development.

In the context of substance use treatment, effective coping strategies are essential as they empower individuals to handle triggers, cravings, and high-risk situations that may lead to a return to substance use. By focusing on this aspect, the Coping Behaviors Index assists counselors in developing tailored interventions that enhance their clients' ability to maintain sobriety and improve their overall well-being.

The other options—employment opportunities, drug dependence severity, and intelligence quotient—do not align with the specific purpose of the Coping Behaviors Index, which distinctly targets the coping mechanisms relevant to relapse prevention. This makes the choice of measuring relapse prevention mechanisms a clear and suitable focus for the index.
