On the other hand buy acivir pills 200mg on line hiv infection symptoms signs, an appropriate knowledge base increases personal resources and promotes the confidence and comfort to impart knowledge buy discount acivir pills 200 mg hiv infection of cns. Similarly, by providing sufficient knowledge on the subject, unrealistic or negative expectations regarding the results and benefits obtained by implementing the program are corrected. Risk and protective factors are important not only to prevent or reduce drug use, but also to improve and increase personal potential. Explicitly pointing this information out, contributes to the perception of other benefits or results along with those concerning drug use. Teachers are sometimes reluctant to implement the program, because they consider the idea that a program, in a few sessions, can act against the phenomenon of drug use naive. Although it is also important to clarify that both research and the influence of risk and protective factors is a matter of probabilities. Likewise, the provision of adequate knowledge of the program fundamentals generates a greater understanding of the key concepts and components. This contributes, in turn, to decreased deviation from the original protocol and facilitates its implementation. Finally, in the application of evidence-based programs, it is essential that teachers applying the session generate a high level of interaction, guide the class towards the session objectives and create an atmosphere of safety and feedback. To be properly employed, the interactive methodology requires a suitable skill set and a certain degree of comfort. In conclusion, ensuring that teachers have the adequate knowledge and skills and feel comfortable applying the drug prevention programs requires a certain type of training. Principal features of training that optimize the fidelity of the programs There are very few studies that analyze the actual impact that training has on the performance of teachers and/or the results of students. The few studies that have assessed teacher training have focused primarily on analyzing whether some training strategies or components are more efficacious than others. In these studies, when strategies have produced positive effects, these have occurred mainly in the degree of knowledge acquired by teachers and, to a lesser extent, in the attitudes held towards preventive approaches (Dusenbury, et al. With regard to the features of the teacher training, studies indicate that it should include direct training on the application of sessions, employing videos and role-playing and be followed up with booster sessions. Furthermore, training is best appreciated when it is done by the program designers, offered to motivated teachers and lays out concrete and detailed instructions. Nevertheless, it has been found that after live training, in comparison with video training, there is a greater likelihood of applying role-playing programs and techniques (Basen-Enquist et al. However, it is argued that more extensive training is associated with greater fidelity (Fors and Doster, 1985; Smylie, 1988; Perry et al. The first programs developed to prevent drug use were based on: a) the transmission of information and the use of fear. Resistance skills-based programs focus on countering the influence on adolescents by: a) the leisure and entertainment industry. Personal skills improvement programs emphasize components such as: a) resistance skills training against the offer of drugs. Based on their implementation methodology, school-based programs can be classified into: a) interactive and non-interactive programs. In reference to the activities, strategies or components that that constitute the efficacious elements of a school-based program, research highlights that: a) their preventive potential depends on the methodology with which they are applied. However, when transmitting information, it should be borne in mind that the information: a) be subjective and moralistic. Among the elements that efficacious school-based programs include, specialized literature highlights: a) informative talks given by former drug users. The implementation of a program in the school setting is enhanced by: a) the inclusion of visits to nightlife venues. The assessment phase that consists of both describing the problem and identifying strategies to address it is called: a) process assessment. Evaluating the extent to which a school-based program has been implemented with fidelity to the planned design is known as an assessment of: a) the efficiency of the program. The field journals filled in by teachers are an example of an indicator that we can employ in the evaluation of: a) results. The evaluation of outcomes may include judgments about: a) the efficacy, efficiency and effectiveness of the program. Impact assessment differs from the assessment of results: a) in assessing the percentage of the target population that receives the program.
