The present study aims to test and rigorously evaluate the effectiveness of a computer-assisted motivational interviewing (CAMI) intervention that has already been shown to be successful with young women by reducing the risk of rapid subsequent birth among adolescent mothers, and applying this intervention to young men.
The purpose of the intervention is to increase condom use, increase female partner use of moderately or highly effective contraception, and increase completion of a reproductive health visit and STI/HIV testing.
The primary hypothesis is that the CAMI-TPP (CAMI aimed at Teen Pregnancy Prevention) intervention will increase the proportion of participants who do not engage in risky sex, report condom use at last intercourse as well as partner use of contraception compared to those in the Fitness group. It is also predicted that young men who receive the CAMI-TPP will report higher completion of a reproductive health service visit with sexually transmitted infection (STI) testing over the course of study participation compared to those in the CAMI-Fitness (CAMI aimed at healthy diet, physical activity and tobacco avoidance) group.
Most teen pregnancies (82%) in the United States are unintended. Actively engaging young men in preventing teen pregnancy is a necessary and central component to effecting change. Young men, aged 15-19 and 20-24 years, father most of the children born to teen mothers. Few interventions have been designed specifically or shown to be effective for young men in reducing teen pregnancy.
Counseling and feedback based on Motivational Interviewing (MI) principles demonstrated greater success than standard, didactic advice in several domains of behavior change. The effectiveness of this type of counseling to alter young men's sexual and contraceptive behaviors has not been rigorously evaluated.
Participants will be randomly chosen (like flipping a coin) to take part in one of the two MI projects, and you will get coaching and use an app for that project to improve your health. One project is on teen pregnancy prevention and the other is on healthy eating, physical activity, and avoiding cigarettes. Participants will use an app via phone to do the project, answer survey questions, keep track of health, and learn more about healthy behaviors.
Three hundred young men, ages 15 to 24 years, will be randomized to one of two intervention arms, a modified CAMI aimed at Teen Pregnancy Prevention (CAMI-TPP) or a CAMI aimed at healthy diet, physical activity and tobacco avoidance (CAMI-Fitness). The two interventions are identical in length and timing but vary in the target behavior focus (pregnancy prevention versus fitness).

Participants will be randomized through a permuted random blocks assignment procedure with block stratification (by age group). Strings of varying length (2, 4, 6, 8, for example), with equal allocations T and C (randomly ordered) within a string, are combined to produce a single, long string of T and C combinations (e.g. TTCCTCTTCCC, etc.). Because the long string is made up of blocks of T and C strings with equal allocations of Ts and Cs, the observed percentage of the sample in the treatment condition will always be very close to 0.5, and the true P(T) for all observations will be 0.5. Randomization will be conducted via an algorithm on the online portal at the time of enrollment in order for the project coordinator to assign the participant to an intervention arm.
