Study start date: March 1, 2025Actual date on which the first participant was enrolled.

The study is exploring a new digital tool called the Probation/Parole and Reentry Coach Application (PARCA). This tool is designed to assist individuals who are on probation or parole as they transition back into the community. By using techniques like motivational interviewing and cognitive behavioral strategies, the application aims to help these individuals identify and tackle personal issues, set and achieve goals, and successfully complete their supervision terms. The importance of this study lies in its potential to improve the outcomes for people on probation or parole, making their reentry process smoother and more effective. Participants in the study will engage with the PARCA application, which guides them through identifying their personal challenges and setting achievable goals. The application also tracks progress and rewards accomplishments, encouraging continued effort towards their objectives. Probation or parole officers will have access to this information to better support and supervise the participants. The study will measure how effectively PARCA helps in improving supervision outcomes by examining the progress made towards goals and overall reentry success. This approach could offer significant benefits by providing structured support and motivation for individuals during a critical time in their lives.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
50 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are placed into groups randomly, like flipping a coin. This ensures that the study is fair and unbiased, making the results more reliable. By assigning participants by chance, researchers can better compare treatments without external influences.

Other Ways to Assign Participants
Non-randomized allocation: Participants are assigned based on specific factors, such as their medical condition or a doctor's decision.
None (Single-arm trial): If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
In this study, all participants receive the same treatment. This approach is often used to evaluate the effects of a single intervention without comparing it to another.

Other Ways to Assign Treatments
Parallel assignment: Participants are split into separate groups, each receiving a different treatment.
Cross-over assignment: Participants switch between treatments during the study.
Factorial assignment: Participants receive different combinations of treatments.
Sequential assignment: Participants receive treatments one after another in a specific order, possibly based on individual responses.
Other assignment: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Double-blind: Neither participants nor researchers know which treatment is given.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Treatment Groups
Study Objectives
2 intervention groups 

are designated in this study

This study does not include a placebo group 

Treatment Groups
Group I
Experimental
Officers and clients are using the application of PARCA which is on their phone and a web-based application. PARCA is a tool to detail goals and progress towards goals
Group II
No Intervention
Officers and clients are not using any new procedures or tools; they are using standard care.
Study Objectives
Primary Objectives

This represents the number of days that the individual starts treatment based on the day that they started supervision. This can be measured in the supervision records. This is an event in the record system like an electronic health record.
Secondary Objectives

This represents the number of times the individual participated in treatment during a 90 day window. This can be measured from supervision records.
