The delivery format of an HIV prevention program that had been efficacious with youths at high risk was modified from seven relatively short sessions over a one- to two-month period to three longer sessions over a one- to two-week period. In contrast to youths in the seven-session program, no change in sexual behavior was observed among those in the redesigned program at three-month follow-up. However, change was apparent in the mediators of high-risk behavior over the same period.
一项对高危青少年有效的艾滋病预防项目，其交付形式从在一到两个月内进行七次相对较短的课程，改为在一到两周内进行三次较长的课程。与参加七节课程项目的青少年相比，在重新设计的项目中，三个月随访时未观察到性行为的变化。然而，在同一时期，高危行为的中介因素却出现了明显变化。
