The Body Awareness Resource Network (BARN) is a system of interactive computer programs designed to provide adolescents with confidential, nonjudgmental health information, behavior change strategies, and sources of referral. These programs cover five adolescent health areas: alcohol and other drugs, human sexuality, smoking prevention and cessation, stress management, and body management. Made available for 5500 adolescents in Madison (Wisconsin) in October 1982, the system was evaluated in the spring of 1984 through questionnaires answered by 383 seventh, 392 ninth, and 253 eleventh graders. Results showed that the use of BARN was related to certain social and psychological characteristics and provided support for the motives in getting adolescents on the BARN system. Seventh graders reported heavy use of BARN (once a month), ninth graders less use, and eleventh graders less still. The BARN example provides encouragement for computer programmers and information campaigners interested in reaching children and adolescents through interactive computer programs. While the adolescents initially come to the programs for a wide variety of reasons, what keeps them on the system is that it meets their information needs. (Tables of findings are included.) (EL)
