Which of the following is an indicator of successful MAT outcomes?

The hallmark of successful outcomes in Medication-Assisted Treatment (MAT) is often evaluated through various indicators, with one of the most significant being the reduction in substance use alongside improvements in a person's overall quality of life. Reducing substance use signifies that the MAT is effective in helping individuals manage their dependence or addiction, which is the primary goal of such treatment.

Moreover, improvements in quality of life encompass a broader range of factors, including psychological well-being, social functioning, and engagement in productive activities. These aspects are critical as they reflect not just the absence of substance use, but also a person's return to meaningful and fulfilling living. Hence, the combination of reduced substance use and enhanced quality of life collectively demonstrates that the treatment is achieving its intended effects, leading individuals towards recovery and improved life satisfaction.

In contrast, options related to increased drug use, shorter retention in treatment, or increased denial of substance use do not indicate positive outcomes and do not reflect the primary objectives of MAT.
