In a recent study \(^{1}, 380\) high risk adolescents involved in the juvenile justice system were recruited to test an app designed to increase mindfulness and reduce substance use. Participants were randomly and equally assigned to use the app (Rewire) or receive services as usual from the Department of Youth Services. Participants were assessed to determine a baseline for substance use at the beginning of the study, and were asked to complete follow up assessments after 1 and 3 months. Assessments consisted of online surveys asking about substance use, emotion regulation, family demographics, and mindfulness practices. Urine samples were collected at each interview to verify self-reported substance use. a. Describe the treatment group. b. Describe the control group (if there is one). c. Is this study blind, double-blind, or neither? Explain d. Is this best described as an experiment, a controlled experiment, or a placebo-controlled experiment?

Step by step solution

01

Identifying the Treatment Group

The treatment group consists of the adolescents who were assigned to use the app named Rewire. This app is designed to increase mindfulness and reduce substance use among the participants.

02

Identifying the Control Group

The control group in this study includes the participants who did not use the Rewire app but instead received standard services offered by the Department of Youth Services. These services serve as a baseline treatment to compare against the app usage.

03

Determining the Study Type

This study is neither blind nor double-blind. Typically, in a blind study, participants do not know whether they are receiving the experimental treatment or a placebo. In a double-blind study, neither the participants nor the administrators know who belongs to which group. Here, participants likely know if they are using an app or not, indicating that the study is not blind.

04

Classifying the Type of Experiment

This study is best described as a controlled experiment because it includes both a treatment group (using the Rewire app) and a control group (receiving services as usual). The study compares changes in substance use between these groups, following a specific intervention and control.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Controlled Experiment

A controlled experiment is a scientific investigation where one variable is changed at a time while all other variables are kept constant. This helps in establishing a cause-and-effect relationship. Here, the primary aim is to determine the impact of the Rewire app on mindfulness and substance use among adolescents in the juvenile justice system. The participants are split into two groups: the treatment group, who use the app, and the control group, who receive standard services. By comparing results from these groups, researchers can identify any significant effects caused by the app.

In our study, specific steps are taken to control variables, such as:

• Randomly assigning participants to either group, reducing selection bias.
• Conducting baseline and follow-up assessments to track changes over time.
• Using urine samples to verify the accuracy of self-reported data.

These controls help ensure that any changes in substance use are due to the intervention (Rewire app) and not other external factors.

Mindfulness

Mindfulness is a mental practice where individuals focus on being intensely aware of what they are sensing and feeling in the moment, without interpretation or judgment. Its purpose is to foster emotional regulation and improve overall mental health. The Rewire app in this study is aimed at helping adolescents develop mindfulness skills.

The implementation of mindfulness techniques can have several benefits for adolescents:

• Improved emotion regulation, helping them manage feelings that might otherwise lead to substance use.
• Enhanced concentration and focus, which can aid in making better life choices.
• Reduction in stress and anxiety levels, which may decrease the likelihood of turning to substances for relief.

By incorporating mindfulness into the app, the study aims to equip these young individuals with a tool that promotes healthier coping mechanisms.

Juvenile Justice System

The juvenile justice system is a set of agencies and processes established to handle minors who are accused of committing illegal acts. This system focuses on rehabilitation rather than punishment, emphasizing the guidance and support needed for a minor's development.

Key goals include:

• Preventing re-offense by offering counseling, education, and vocational training.
• Addressing underlying issues such as substance use or emotional challenges.
• Ensuring safe environments for children with structures that encourage reintegration into society.

In this study, the system plays a crucial role in providing the standard services that serve as the control in the experiment. These standard services offer a baseline to which the new intervention, the Rewire app, will be compared. The aim is to determine if the app can enhance the existing services in reducing substance use among high-risk adolescents.

Substance Use Reduction

Substance use reduction is a strategic approach to decrease or eliminate the consumption of drugs or alcohol. This is essential within high-risk populations like adolescents in the juvenile justice system who may have started using substances due to peer pressure, stress, or other environmental factors.

The reduction strategies often include:

• Counseling and therapy sessions to understand the root cause of substance use.
• Education on the hazards of substance abuse and the benefits of a sober life.
• Mentorship programs to offer support and positive role models.

The Rewire app is targeted at aiding these strategies by integrating mindfulness practices to offer adolescents an alternative coping mechanism. By comparing substance use in the app users with those receiving regular services, the study explores whether this innovative approach is effective in addressing substance use challenges in the target group.
