Age of the target audience at time of intervention is thought to be a critical variable influencing the effectiveness of adolescent sexual risk reduction interventions. Despite this postulated importance, to date, studies have not been designed to enable a direct comparison of outcomes according to age at the time of intervention delivery.
We examined outcomes of 598 youth who were sequentially involved in two randomized controlled trials of sexual risk prevention interventions, the first one delivered in grade 6 (Focus on Youth in the Caribbean [FOYC]) and the second one in grade 10 (Bahamian Focus on Older Youth [BFOOY]). Four groups were examined, including those who received (1) both treatment conditions, FOYC and BFOOY; (2) FOYC in grade 6 and the control condition in grade 10; (3) the control condition in grade 6 and BFOOY in grade 10; and (4) both control conditions. Intentions, perceptions, condom-use skills, and HIV-related knowledge were assessed over 60 months.
Data showed that those who received both interventions had the greatest increase in condom-use skills. Youth who received FOYC in grade 6 had greater scores in knowledge and intention.
These results suggest that youth receive the most protection with early and repeated exposure to interventions. These findings suggest that educators should consider implementing HIV prevention and risk reduction programs as a fixed component of education curriculum beginning in the preadolescent years and if possible also during the adolescent years.
干预时目标受众的年龄被认为是影响青少年性风险降低干预措施有效性的关键变量。尽管有这种假定的重要性,但迄今为止,尚未有研究旨在能够根据干预实施时的年龄对结果进行直接比较。
我们研究了598名青少年的结果,他们依次参与了两项性风险预防干预的随机对照试验,第一项在六年级进行(加勒比地区关注青少年[FOYC]),第二项在十年级进行(巴哈马关注大龄青少年[BFOOY])。研究了四组,包括那些接受(1)两种治疗条件,即FOYC和BFOOY的;(2)六年级接受FOYC且十年级接受对照条件的;(3)六年级接受对照条件且十年级接受BFOOY的;以及(4)两种对照条件的。在60个月内评估了意图、认知、 condom使用技能和与艾滋病毒相关的知识。
数据显示,接受两种干预的人在condom使用技能方面的提高最大。六年级接受FOYC的青少年在知识和意图方面得分更高。
这些结果表明,青少年通过早期和反复接触干预措施获得的保护最大。这些发现表明,教育工作者应考虑将艾滋病毒预防和风险降低计划作为教育课程的固定组成部分,从青春期前开始实施,如果可能的话,在青少年时期也实施。
