Program Objectives

The goal of Girl2Girl is to provide content on teen pregnancy prevention, STI, communication skills, and healthy and unhealthy relationships to cisgender girls between the ages of 14 to 18 who identify as lesbian, bisexual, or queer. 

Program Content

Girl2Girl content focuses on teen pregnancy prevention and is guided by the Information-Motivation-Behavioral model. Topics covered through scripted text messages include male and female condom use and access, types of birth control, healthy and unhealthy relationships, and prevention of unintended pregnancy and STI. Additional content includes topics and scenarios relevant to sexual decision making. The program’s content is tailored based on sexual experience and sexual identity. In addition to receiving program content, participants are paired with another participant (a Text Buddy) they can text for support throughout the program. 

Program Methods

The program is delivered through text messages.

Program Structure and Timeline

Girl2Girl is a 20-week teen pregnancy prevention program. During the first seven weeks of programming, participants receive four to 12 text messages per day. They then receive one message two or three days per week for the following 12 weeks. The final week of programming is the booster period, which is intended for review of content delivered during program delivery. Participants receive eight to 15 messages during the one-week booster period. All Text Buddy messages are run through a server to protect participants’ privacy.

Staffing

Staffing needed to implement the program includes staff to monitor the Text Buddy conversations, answer participant questions, and recruit and enroll participants.

Program Materials and Resources

Participants are required to have access to a text-capable phone. Unlimited text messaging plans are encouraged but not required.

Additional Needs for Implementation

None.

Fidelity

The developer will ensure when text messages are sent and their receipt by the intended recipient.

Staff Training

Formal staff training is not required to implement the program. Staff will monitor the Text Buddy conversations, answer participant questions, and recruit and enroll participants.

Technical Assistance and Ongoing Support

Girl2Girl is a texting intervention; typically, implementers do not need technical assistance or ongoing support during program implementation. However, implementers can contact Michele Ybarra at michele@innovativepublichealth.org if there is a need for technical assistance or ongoing support.

Allowable Adaptations

Adaptations are allowed in consultation with the developer. To discuss adaptations, contact Michele Ybarra at michele@innovativepublichealth.org.

The program was evaluated using a randomized controlled trial involving cisgender female youth ages 14–18 identifying as not exclusively heterosexual, who were recruited across the United States through Facebook and Instagram advertisements. Participants were randomly assigned to either a treatment group that received the 20-week Girl2Girl program or a control group that received similarly intense text messaging for the same length of time with content that was not focused on preventing teen pregnancy. Surveys were administered immediately after enrollment, which was right before the program started (baseline), and immediately after the 20-week program ended (5 months after study enrollment). The study found that at program end, teen girls participating in the program reported having used condoms while having sex significantly more often than the control group had in the past three months (effect size = 0.03) and reported significantly fewer sex acts without a condom in the past three months (effect size = -0.05). Those program effects held for the full sample and the subgroup that was sexually active at baseline (effect sizes = 0.05 and -0.29, respectively, for the subgroup on condom use during sex and having fewer sex acts without a condom). The study also found that at program end, teen girls participating in the program and those in the control group were not significantly different from each other in their reporting of abstaining from penile-vaginal sex in the past three months. Those null findings held for the full sample and the subgroup that was sexually active

Notes

Some study entries may include more than one citation because each citation examines a different follow-up period from the same study sample, or because each citation examines a different set of outcome measures on the same study sample. A blank cell indicates the study did not examine any outcome measures within the particular outcome domain or the findings for the outcome measures within that domain did not meet the review evidence standards.

Information on evidence of effectiveness is available only for studies that received a high or moderate rating. Read the description of the review process for more information on how these programs are identified.
