Positive Prevention PLUS is a school-based adolescent pregnancy prevention program that consists of eleven 45-minute lessons aimed at students in grades 9 through 12. It is delivered by trained classroom teachers during the normal school day in science, health, or physical education courses. The 11-unit curriculum includes lessons on the benefits of abstinence, assertive communication, refusal skills, accessing reproductive health services, condom negotiation, and condom use. Students practice communication about abstinence and risk reduction skills through scripted role play and other interactive activities.

In LaChausse (2016), the treatment was completed over a 3-week period where educators were expected to complete 11 lessons consecutively. Teachers completed a rigorous training schedule with program developers to ensure fidelity of implementation. First, teachers completed a 2-day training that consisted of an overview of the project and opportunities to practice teaching a lesson. Next, teachers completed an online training program to review key components and to observe each lesson being taught by a veteran teacher. About 1 week before implementation, teachers were also given a 1-day refresher to emphasize key lessons and address any concerns about program implementation.
The current version of the curriculum includes 13 sessions. The two additional lessons cover: STDs and Safe Surrender per California requirements.
Primary Evidence Base for Certification
LaChausse (2016) found that, relative to the control group, students in the treatment group were less likely to report having had:
Primary Evidence Base for Certification
The one study Blueprints has reviewed (Study 1) meets Blueprints evidentiary standards (specificity, evaluation quality, impact, dissemination readiness). The study was conducted by an independent evaluator.
Study 1
LaChausse (2016) conducted a cluster randomized control trial in which 21 schools (with 4,267 students) were randomly assigned to a treatment group that received the Positive Prevention Plus program (n = 11 schools) or a control group that received no sexuality-related classroom instruction or school-wide activities (n = 10). Student self-report data were collected at baseline and 6-months following program completion. Outcome measures included three behavioral measures related to sexual activity: (1) ever had sexual intercourse; (2) ever been pregnant or gotten someone pregnant; and (3) ever had sexual intercourse without using birth control in the past 3 months.

Subgroup differences in program effects by race, ethnicity, or gender (coded in binary terms as male/female) or program effects for a sample of a specific race, ethnic, or gender group.
Study 1 (LaChausse, 2016) did not test for subgroup effects defined by race, ethnicity, gender, sexual identity, economic disadvantage, geographic location, or birth origin.
Sample demographics including race, ethnicity, and gender for Blueprints-certified studies:
Of the students in Study 1, 36% were white, 18% were black, 8% were Asian, and 74% reported Hispanic ethnicity. More than half (54%) of the sample was female.
Two-Day trainings are highly recommended for school teachers, school nurses, and community agency staff intending to present the Positive Prevention PLUS to adolescents and young adults in a classroom or community setting. Training is conducted by Cardea Services Inc. of Oakland, CA. Trainings include familiarization with the curriculum, laws, trauma-informed instruction, gender-related issues, plus actual participant teach-backs.

All benefit-cost ratios are the most recent estimates published by The Washington State Institute for Public Policy for Blueprint programs implemented in Washington State. These ratios are based on a) meta-analysis estimates of effect size and b) monetized benefits and calculated costs for programs as delivered in the State of Washington. Caution is recommended in applying these estimates of the benefit-cost ratio to any other state or local area. They are provided as an illustration of the benefit-cost ratio found in one specific state. When feasible, local costs and monetized benefits should be used to calculate expected local benefit-cost ratios. The formula for this calculation can be found on the WSIPP website.
$3000 for a two-day training of up to 30 people (plus trainer travel expense), provided by Cardea Services.

Curriculum package: $279 each (+ tax and shipping), ordered online from www.positiveprevention.com
Student workbooks can be purchased in Spanish or English: $6 each (optional).
Each edition features engaging and easy-to-follow semi-scripted lessons and support materials. The curriculum will arrive shrink-wrapped and three-hole punched including lesson dividers and sample Student Workbook, ready to be placed into a three-ring binder.
No additional licensing fees.
For school teachers, also add in the cost of a substitute teacher for two days per teacher attendee (approx. $80-120 per day).
If Student Workbooks are not purchased, also add approx. 26 worksheets minimum per student.
Cardea Services typically arranges space with the school district for a district-only training or for an "open training" (to which others may be invited) at their site; procedures are similar for an agency-based training for its health educators.
Some clerical time is required to arrange training space, order materials, register attendees if the school district or community agency is hosting the training.
School or agency must provide the teacher/health educator with a computer and projector for the lesson slides.
It is recommended that the Activity Cards (masters provided) be run on cardstock (approx. 100 8-1/2" x 11" sheets of cardstock).
Parent notification letters are typically duplicated and mailed/distributed by school districts.
Recurring cost of $6 per Student workbook, unless school/agency chooses to duplicate student worksheets themselves.
In California, the law requires retraining of teachers with updated curriculum materials approx. every three years.
One lesson requires NaOH and phenolphthalein for a demonstration; additional materials recommended include sample birth control methods, latex gloves, masking tape or pins.
Schools typically train and equip a number of designated (science or health) teachers to implement the curriculum; community-based agencies will train and equip a smaller cadre of health educators to service school- or community-based teen populations.

Some districts and agencies may request participation in a Training of Trainers (TOT) to build capacity within their own organization to (re)train teachers and health educators. This may be negotiated with Cardea Services on a case-by-case basis.
In this example, a high school implements the Positive Prevention PLUS program in ninth grade required courses, either health or science. Four teachers deliver the program to 250 students. The expenses listed below do not include taxes and shipping of materials.
| Initial two-day training | $3,000.00 |
| Trainer travel | $1,500.00 |
| Substitute teachers for 2 training days @ $200/teacher | $800.00 |
| Curriculum package @ $279/teacher | $1,116.00 |
| Student workbooks @ $6/student | $1,500.00 |
| Total One Year Cost | $7,916.00 |
With 250 students served by Positive Prevention PLUS, the Year 1 cost per student is $31.66.
Positive Prevention PLUS, as a sexual health education and teen pregnancy prevention program designed to be delivered in schools, can be funded with prevention and health promotion dollars focused on high-risk adolescents, as well as education funds.
To the extent that existing health education and pregnancy prevention programs are not evidence-based, a local school district or community agency can consider re-directing teaching time and funds into Positive Prevention PLUS to get better outcomes.
Local school districts may support Positive Prevention PLUS with school district funding. In addition, state and local health departments as well as city youth development offices may offer grants supporting sex education and pregnancy prevention.

The program draws on social cognitive theory, which posits that behavior change occurs through several constructs, including observational learning, behavioral capability, outcome expectations, and self-efficacy.

Evaluation Methodology
Design:
Recruitment: High schools across six districts in Southern California with data indicating high adolescent birth rates and a lack of comprehensive sexuality education or adolescent pregnancy prevention programming were approached to participate. Criteria for selection into the study included whether schools were able to implement an adolescent pregnancy prevention program, maintain the treatment and control contrast, and provide access to eligible students. Twenty-two schools were assessed for eligibility and one school was dropped for not meeting inclusion criteria. A total of 7,042 students were assessed for eligibility and provided the opportunity to consent to participate. After excluding one school that was not eligible for participation, 4,267 parental consents were obtained and randomization into treatment and control occurred.
Assignment: A total of 21 schools (with 4,267 students) were randomly assigned to condition, with 11 schools (n= 2,483 students) in the treatment group and 10 (n = 1,784) in the control group. Students in the control group classrooms received the standard health, science or physical education curriculum. Schools and teachers in the control group were asked to refrain from providing any sexuality-related classroom instruction or school-wide adolescent pregnancy or STD prevention-focused activities, though they were allowed to discuss human reproduction if relevant to their curriculum (for example, in a biology course).
Attrition: No attrition occurred at the school-level. There were 3,554 participants that completed the baseline survey for an overall baseline attrition rate of 17%. At 6-months follow-up, 3,490 students completed a survey (for an overall attrition rate of 18%).
Sample:
The overall population of the sample was not reported, though demographics were reported by condition. Of the students in the treatment group, 34% were white, 18% were black, 8% were Asian, and 74% reported Hispanic ethnicity. Meanwhile, 38% of students in the control group were white, 18% were black, 9% were Asian, and 73% reported Hispanic ethnicity. More than half the overall sample was female, while 52% of students in the treatment group and 56% in the control group were female.
Measures:
Outcomes were assessed using a student, self-report yes/no question to the following items:
Analysis:
The analysis used multi-levels models with robust standard errors, random effects at the school level, and baseline covariates for gender and Hispanic or not. While outcomes were assessed at baseline (see Table 1), it is not clear whether these baseline outcomes were included as covariates. The Benjamini-Hochberg adjustment was made for the three outcomes assessed.
Intent-to-Treat: All available data of students were analyzed based on the condition to which they were initially assigned which is in line with intent-to-treat protocol. Additional analyses used multiple imputation to include all data.
Outcomes
Implementation Fidelity: Teachers completed 95% of the lesson activities scheduled to be delivered. Ninety-one percent of the students attended all of the offered lessons. Seventy-three percent of the lessons received a high-quality rating, however no explanation or quantitative data was provided for how this rating was assessed. In terms of diffusion, only 14% of the participants in the control group reported learning about adolescent pregnancy prevention-related topics, whereas treatment group students reported learning 60% of the adolescent pregnancy prevention-related health topics.
Baseline Equivalence: Tests used the analytic sample, but not the randomized sample. After adjustment for clustering, the tests showed no significant differences on any of the nine baseline measures (Table 1).
Differential Attrition: The attrition rate differed across conditions by approximately 8% at baseline and 8% at the 6-month follow-up, with a higher attrition rate in the control group. Tests found no significant differences between the intervention and control groups in the proportion of dropouts who were female, were Hispanic, ever had sex, ever had been pregnant, and had not used birth control. In addition, per Table 1, equivalence for the analytic sample was established with no statistically significant differences in demographics or outcomes detected between the control and treatment groups at baseline.
Posttest: At posttest, the study found significant impacts on the participants' likelihood to engage in sexual intercourse and to engage in sexual intercourse without birth control. Relative to the control group, participants in the treatment group were approximately 4 percentage points less likely to have had sex at 6-month follow-up. In addition, participants in the treatment group were approximately 2 percentage points less likely than students in the control group to have had sex without birth control at 6-month follow-up. There were no significant differences between groups in getting pregnant/having gotten someone pregnant at 6-month follow-up.
However, sensitivity tests found that use of multiple imputation reduced all the program effects to non-significance and use of logical imputation (i.e., using answers to some questions to impute answer to others) reduced the program effect on use of birth control to non-significance.
Long-Term: , Not conducted.
Registry
The clinical trial registry for the study can be found at Clinical.Trials.gov (see https://clinicaltrials.gov/ct2/show/NCT02540278?term=LaChausse&rank=1). As the primary outcomes, the registry lists had sex (ever and last 6 months), been pregnant or gotten someone pregnant (ever and last 6 months), and sex without birth control (last 3 months). These outcomes and the other registry details correspond to those used in the study.
