4. EPIDEMIOLOGY ETIOLOGY EFFICACY EFFECTIVENESS DISSEMINATION 1. Identify problem or disorder(s) and review information to determine its extent 2. With an emphasis on risk and protective factors, review relevant information- both from fields outside prevention and from existing preventive intervention research programs 3. Design, conduct, and analyze pilot studies and confirmatory and replication trials of the preventive intervention program 4. Design, conduct, and analyze large- scale field trials of the preventive intervention program 5. Facilitate large-scale implementation and ongoing evaluation of the preventive intervention program in the community. The preventive intervention research cycle. Preventive intervention research is represented in boxes three and four. Note that although information from many different fields in health research, represented in the first and second boxes, is necessary to the cycle depicted here, it is the review of the information, rather than the original studies, that is considered to be part of the preventive intervention research cycle. Likewise, for the fifth box, it is the facilitation by the investigator of the shift from research project to community service program with ongoing evaluation, rather than the service program itself, that is part of the preventive intervention research cycle. Although only one feedback loop is represented here, the exchange of knowledge among researchers and between researchers and community practitioners occurs throughout the cycle.

31. SDRG Entries are 3-year running averages of the prevalence of each of the specified acts. The violence index is defined as the percent committing any of the specified following five acts, with no missing data allowed: hit an instructor or supervisor; gotten into a serious fight in school or at work; taken part in a fight where a group of your friends were against another group; hurt somebody badly enough to need bandages or a doctor (assault with injury); used a knife or gun or some other thing (like a club) to get something from a person (robbery with a weapon). 95% confidence intervals for the violence index are all less than ± 2.5%; for assault, less than ± 2%; for robbery, less than ± 1.1%.
