In April 1989, the National Institute on Drug Abuse (NIDA) convened a meeting of 17 Acquired Immune Deficiency Syndrome (AIDS) education and training experts to discuss AIDS and substance abuse training and to examine NIDA-initiated training efforts. Participants were asked to develop specific recommendations for NIDA regarding its role in providing comprehensive and systematic AIDS training to substance abuse counselors and outreach workers. Chapter I of this report sketches the format of the NIDA meeting. Chapter II gives historical context to the discussions that took place at the meeting, describing the evolution of NIDA's National Training System from its inception in the early 1970s to its dismantling in 1981. Chapter III summarizes the conference discussions and recommendations of the participants in the four areas of inquiry for the workshop: (1) developing an AIDS training plan; (2) developing an AIDS curriculum; (3) developing a system for delivering AIDS training; and (4) developing AIDS trainers. For each topic, the chapter reviews the status of knowledge and practice, identifies gaps and needs, suggests approaches for evaluation, and offers recommendations for improvement. Chapter IV notes the three major themes that surfaced during the meeting: (1) the need to professionalize the chemical dependency work force; (2) federal-state partnerships; and (3) the maturing of the training leadership. The chapter also discusses NIDA's AIDS activities in such areas as training development, supervision, sensitivity to youth and minorities, and cooperation with state efforts. A list of meeting participants, including their addresses and telephone numbers, is appended. (NB)
