The goal of this randomized trial is to learn if the Unstained intervention has a positive impact on the sexual health behaviors of sexually active youth between the ages of 14 and 22 years old who are at risk for or involved in the legal system. The primary research questions it aims to answer are:

• Three months after being offered the intervention, does Unstained impact youth's receipt of sexually transmitted infection testing in the past four months?
• Nine months after being offered the intervention, does Unstained impact youth's frequency of having vaginal and anal sex without condoms in the past four months?

Researchers will compare participants randomized to receive Unstained (treatment group) to participants randomized to receive a control condition that contains no sexual or reproductive health information (control group).

Participants randomized to the treatment group will be offered Unstained as a virtual, individual-based intervention delivered during three ~60 minute sessions over a 3-6 week period. Participants randomized to the control group will be offered a virtually delivered control condition.

This is an individual-level, randomized control trial to rigorously evaluate the impact of the Unstained intervention. Participant outcomes will be assessed using self-reported, individual-level data gathered using a structured questionnaire administered at three time points: baseline (enrollment); three months post-intervention (five months after baseline); and nine months post-intervention (eleven months after baseline).

Inclusion Criteria:

• United States resident
• Owns or has regular access to a personal device with internet access
• Comfortable reading, speaking, and writing in English
• Has had vaginal or anal sex in the past 3 months
• At risk for or involved in the legal system

Exclusion Criteria:

• Currently trying to start a pregnancy
• Currently in jail or being detained in a facility
• Enrolled in an ongoing PRG-run TPP study
• Identified as fraudulent
• Participating in another known OPA-funded research study

A dataset will be prepared at the conclusion of the study, which includes de-identified individual-level data on all study participants who contributed self-report data. Respondents will be represented only by a research ID number. Included in the dataset will be self-report data collected across all survey administrations (including demographic characteristics, sexual behaviors, and theoretical antecedents to those behaviors) and select information on program participation (e.g., which program components were completed). Basic data cleaning steps will be taken in order to ensure data are unidentifiable and to increase usability.

The individual participant dataset will become available twelve months after the study has concluded.
