Detailed Description
The conceptual framework for the intervention and educational materials was based on the model of the Information-Motivation-and-Behavioral-Skills proposed by Fisher and Fisher, 2000. This model emphasizes that adequate information regarding risk sexual behavior, changing the motivational component and training in behavioral skills can influence initiation and maintenance of protective sexual behaviors.
The research group that was constituted by a pediatrician, a psychologist, and a sociologist, designed the educational materials. All the research team members have experience in educational interventions. The academic basis to develop the materials were two books titled: "You, your life, your dreams" developed by International Family Care (2007) and "Your future in freedom, for responsible sexuality and reproductive health" published by the Government of the Federal District and the Secretary of Education of the Federal District of Mexico City (2008). Investigators also took into account the statistics on the sexually transmitted diseases and adolescents' pregnancies of the World Health Organization, 2012 National Health and Nutrition survey, the National Register of AIDS cases, and information from the Planned Parenthood Federation of America.
Investigators designed teen-friendly educational materials, to do so, investigators used "avatars" from www.bitstrips.com, which are the comics for teenagers. Investigators created two central characters a teenage boy and a teenage girl who present the information in the form of dialogs and talk about their own and friend's experiences.
Two experts in the area of adolescents' sexual and reproductive health reviewed the educational materials; then, 20 adolescents between 14 and 15 years participated in three rounds of pilot testing. Both, the teenagers and their parents accepted to participate in this phase through verbal informed consent.
Investigators used the snowball sampling technique to choose the teenagers that took part in the pilot phase, which included ten boys and ten girls, with an average grade point of 8.5 (range 8.0-9.0). Their families were of different types (nuclear, single-parent, extended), and their parents had varying levels of education. Most adolescents (18) had not begun sexual activity, and only two reported being sexually active. Experts and teens were asked if the educational information was clear, understandable and if it used appropriate language for teens, or if it was contradictory, uncomfortable, or boredom. The teens were asked to evaluate whether they liked or not each educational session (using a scale of 1 to 3, where 1 = No, I do not like it, 2 = I like it more or less, 3 = I like it) and to explain why they disliked the educational information. The final version of the educational material was produced taking into account the comments and suggestions of experts and teens, which rated the information highly. Although most adolescents who participated in the pilot testing had not started their sexual life, they reported that the information was clear and interesting.
Description and evaluation of the intervention The study materials are available on the Internet web page (http://tu-ssexual.com), which can be accessed with the participant e-mail address and a centrally assigned password.
The intervention will include an introduction and four educational sessions and will last one month (one session per week) followed by a three-month follow-up. Teens will be allowed to access to a weekly session at any time and as often as he/she likes. However, the sessions will be consecutive, so teens cannot be able to access to the next session without finishing the previous one. Each session has the duration of one hour on average and ends with overview questions. Additionally, at the end of the each session teens will be asked ¿what they like and dislike about the session? And the answers will be recorded in the study database.
Furthermore, during the intervention and follow-up booster e-mail messages will be sent to the teens of the intervention group. "Booster messages" will emphasize main points of the educational sections and will be sending 2-3 per week from the second week of the intervention.
Information on the study variables will be obtained through the internet-based self-applied questionnaire and collected on three occasions: when the adolescents enters into the study (baseline), once the intervention is completed (at one month) and after three months of follow-up (fourth month).
