All4You2! is a program to prevent HIV, other STD and pregnancy among students ages 14–18 in alternative education settings. The primary goal of the program is to reduce the risk of pregnancy and/or STD, including HIV, by reducing the number of students who have unprotected sexual intercourse (either by increasing use of effective birth control and/or condom use or reducing the frequency of sexual intercourse). The program also aims to change key determinants related to sexual risk taking, such as attitudes, beliefs and perceived norms. This approved adaptation of All4You! consists of 15 skills-based classroom lessons, and does not include a service-learning component.

All4You2! is a program to prevent HIV, other STD and pregnancy among students ages 14–18 in alternative education settings.



The primary goal of All4You2! is to reduce the risk of HIV, other STD and pregnancy by reducing the number of students who have unprotected sexual intercourse (either by increasing condom use and use of other protection or reducing sexual intercourse). The program also aims to change key determinants related to sexual risk taking, such as attitudes, beliefs, and perceived norms.

All4You2! is delivered using a variety of interactive strategies such as stories, brainstorming, games, small-group work, advice columns, roleplays and videos.

As a result of participating in All4You2! students will acquire:

  • Functional knowledge regarding STDs, including behaviors that increase risk and behaviors to prevent them
  • Understanding of the influence of multiple partners on STI transmission and the physical and emotional consequences of sexual activity
  • Negotiation and refusal skills
  • Skills for identifying and handling risky situations, establishing healthy relationships and ending relationships in healthy ways
  • Contraception and condom use skills
  • Strategies for overcoming barriers to preventing HIV, other STI and pregnancy
  • Knowledge of resources for HIV/STI and pregnancy testing and treatment


Populations Served & Setting

All4You2! is primarily for youth ages 14 to 18 in alternative school settings. The program could be used in a community setting if retention of youth can be maintained over the 15 sessions.

Length of Program

The program consists of 15 50-minute lessons to be taught from 1 to 3 times a week.


Program Elements

The All4You2! Basic Set includes the teacher’s guide in a 3-ring binder that includes an informative introduction, full set of teacher instructions, teacher background materials, and appendixes with additional background information; student workbooks and required pamphlets (STD Facts for Teens and Birth Control Facts for Teens) for one classroom of 30 students; and a DVD on STD.

Student workbooks are required for every student. Additional classroom workbook sets of 5 and 30 are available.

An optional LGBTQ Supplement helps teachers build a supportive environment for LBGTQ students. It includes a lesson that can be taught before implementing the intervention as well as suggestions for acceptable adaptations to make program activities more inclusive of LGBTQ youth.

An enhanced set of materials is also available that includes supplemental materials to augment student learning, including DVDs, pamphlets and posters. The enhanced set includes the LGBTQ Supplement.

ETR also provides free downloads of pre- and post-tests and Adaptation Tools.


Staffing Requirements

This curriculum can be used by either classroom teachers or community-based educators. Individuals implementing All4You2! should be knowledgeable about the content, be comfortable discussing the material and answering sensitive questions about sexual risk taking, and have experience using interactive teaching strategies such as roleplaying. Ideally, all educators implementing the program should be trained on its contents and teaching strategies.

Peer leaders are also used to facilitate some of the activities.


Parent/Guardian Notification

It is essential to inform parents and guardians regarding the nature and scheduling of this or any sexual health education program. Prior to implementation of the curriculum, families should receive written notice describing the goals of All4You2! and the nature of the content to be covered. Parents also should be given an opportunity to view the curriculum and related materials if they wish. The vast majority of parents want their children to receive appropriate instruction and be given the information and skills they need to protect their sexual health, but parents/guardians also must be allowed the chance to opt out or exclude their children from participating in the program, if they wish.

Evidence Summary

Research Design

The initial All4You2! study was implemented during 2006-2009, with data collection follow-up extending 18 months after the last enrollment in the study. The evaluation featured a randomized trial involving 47 classrooms (765 young people) in alternative school settings (specifically continuation schools) located in urban areas with diverse populations in Northern California. Classrooms were randomly assigned to one of four conditions: (1) HIV/STI/pregnancy prevention curriculum only, (2) service learning only, (3) HIV/STI/pregnancy prevention curriculum plus service learning, or (4) an attention control curriculum.

Participants included both males and females (53% male) who were an average age of 16.2 years. The majority of young people in the study reported being Hispanic/Latino (37.9%) or African American (22.3%).

Data Gathering

To assess the effectiveness of the intervention, paper-pencil self-report surveys were collected from students three times during the study period: baseline, plus two follow up surveys at 6 and 18 months after baseline.


In general, youth receiving All4You2! HIV/STI and pregnancy prevention curriculum were less likely to have vaginal intercourse without a condom [odds ratio (OR) = 0.58, p=.04]; these effects diminished by final follow up. The program also significantly reduced students' exposure to risky situations and had other effects that were marginally significant (Coyle et al., 2013).

Six months after the baseline survey:

  • Students taking part in All4You2! were less likely to have intercourse without a condom in the previous 3 months than were students in the control group; these effects diminished by the 18-month follow up.
  • Students receiving All4You2! also reported having sexual intercourse fewer times than youth in the control condition, though the difference did not reach statistical significance (p = .09).
  • Students receiving All4You2! reported higher levels of refusal self efficacy than youth in the control group, but these differences were only marginally significant (p = .06).

Eighteen months after the baseline survey:

  • Students receiving All4You2! were less likely to place themselves in risky situations (p = .03) than were youth in the control condition.
  • Students receiving All4You2! reported having sexual intercourse fewer times than youth in the control condition, though the difference did not reach statistical significance (p = .07).

Pre/Post Tests

Classroom teachers can use pre/post tests to examine whether short-term knowledge learning objectives have been met. A simple pretest-posttest assessment design can be used to measure pre-instruction levels and post-instruction changes in student learning.

Your ability to detect student change using this survey may vary and can be affected by numerous factors (e.g., number and content of lessons students receive, student scores at pretest, student motivation and interest in topic and survey, etc.) Improvement on the All4You!2 Knowledge Survey between pretest and posttest can be viewed as supportive, but not definitive, evidence of the curriculum's impact on short-term knowledge learning objectives. A well-designed evaluation study (e.g., using a strong experimental design with a well-matched comparison group and adequate sample size) with more extensive measurement would be needed to provide stronger evidence of curriculum impact.
