The Sub-Saharan Africa region has been more severely affected by AIDS than any other part of the world. The United Nations reported that 26.6 million adults and children are infected with the HIV virus in this region, which has about 10% of the world's population but two thirds of the worldwide total of infected people. The overall rate of infection among adults in Sub-Saharan Africa is 7.5%-8.5%, compared with 1.1% worldwide. AIDS has surpassed malaria as the leading cause of death in Africa and it kills many times more Africans than war. Experts relate the severity of the African AIDS epidemic to the region's poverty. The annual domestic and international expenditure on HIV/AIDS program in Nigeria has been estimated at over $US 400 million, most of which are donated by international and local bilateral government and non-governmental organizations. For most of these expenditures, the evaluation criteria for measuring effectiveness are enshrined in annual percentage changes among adults and children with advanced HIV infection receiving antiretroviral therapy; among women and men who returned for their test results after receiving HIV test; among adults aged 15-49 who reported the use of condom during their last intercourse, or among men reporting the use of condom the last time they had anal sex with a male partner. There are, however, very minimal evaluation reports of the hundreds of education, information, and services developed and implemented by various entities within the social societies in the country to change attitude, behavior or enhance knowledge of Nigerian communities about the disease. This study, therefore, developed a primary purpose to demonstrate that properly planned and carefully executed awareness training programs could, possibly, provide positive effects on the knowledge, attitude, and behavior of young college students regarding HIV/AIDS. A secondary purpose assembled, through literature research, a body of evidence-based knowledge and expenditures on HIV/AIDS that will foster greater awareness among health care providers and other authorities in Nigeria about the importance of evaluation in the arsenals of tools to combat the spread of the disease. Although the three null hypotheses of the study that participation in a HIV/AIDS awareness training program will not improve the attitude, knowledge and behavior of participants after participation in the program were statistically vindicated, the study provided enough evidence-based information to alert government and non-governmental stake holders that the international flow of funds for HIV/AIDS will not continue indefinitely. The three null hypotheses of the study that participation in HIV/AIDS awareness training program will not improve the attitude, knowledge and behavior of participants after participation in the program were statistically accepted. There were, however, percentage changes in participants' pre- and post- intervention knowledge, attitude and behavior data demonstrating that the training did have some positive effects on participants. Recommendations were made about the importance of program evaluations to assess effectiveness, and avoid replicating ineffective programs. Pitfalls to avoid when conducting this type of evaluation especially as an external evaluator were also highlighted.
