ATN 032 Index Network Cluster Identification [CRF 18] Dataset in Adolescent Safer Sex Social Network Intervention

Data from Index/Network Cluster Identification Form [CRF 18]
Study Description
A Phase II, one-arm, pre-/post-test experimental design evaluating the feasibility, acceptability, and preliminary effectiveness of a small-group, peer-network behavioral intervention among adolescent males and females and their friendship networks. Index friends recruited members of their social network to comprise small cohorts of 8 to 16 adolescents who received the group intervention at the same time. The intervention was delivered in six small-group sessions conducted over a three week (two sessions per week) or six week (one session per week) period. The intervention focused on reducing risky sexual behavior, such as the concurrent use of alcohol and marijuana during sex, and increasing condom use.

研究概况
本研究采用二期临床试验（Phase II）单臂前后测实验设计（pre-/post-test experimental design），评估针对青少年男女及其社交友谊网络开展的小型同伴网络行为干预方案的可行性、可接受性及初步有效性。核心招募者（Index friends）通过招募自身社交网络成员，组建8至16名青少年组成的小型队列，同一队列的青少年同步接受团体干预。
该干预方案共包含6次小型团体课程，可采用两种实施周期：3周方案（每周2次课程）或6周方案（每周1次课程）。干预聚焦于降低危险性行为发生率，例如性行为期间同时饮酒与吸食大麻的行为，并提高安全套使用比例。
本研究对象为16至19岁的HIV阴性拉丁裔青少年。
